Chapter1Product OverviewThis chapter provides an introduction to Unicenter®CA-QuickFetch® Runtime Performance Optimizer (Unicenter®CA-QuickFetch®) and describes how it reduces the DASD I/Oassociated with program loading.What Unicenter CA-QuickFetch DoesUnicenter CA-QuickFetch is designed to improve theperformance of your z/OS (and OS/390) operating system.Unicenter CA-QuickFetch eliminates a large amount of the I/Othat is associated with program loading. Program loading occurswhen an application or program requires that a load module bebrought into the processor storage. The load modules reside onDirect Access Storage Device (DASD) volumes in partitioneddata sets (PDSs), which are also called libraries.Program Management is the component of z/OS that isresponsible for locating modules and loading them from aDASD volume into virtual storage. IBM also refers to thiscomponent as Contents Supervision. When an applicationrequires that a load module be brought into processor storage, itissues a macro (LOAD, LINK, XCTL, or ATTACH) that requeststhe module.Product Overview 1–1

What Unicenter CA-QuickFetch DoesThe following steps describe how Program Managementresolves a program load request:1. Program Management first searches for the module in theJob Pack Area (JPA). The JPA is in the private address spaceof the user that requested the load module.2. If the module is not in the JPA, Program Management theninitiates a directory search against the JOB/STEP/TASKlibraries to find the location of the module.3. If Program Management does not find the module in theJOB/STEP/TASK libraries, it searches the Link Pack Area(LPA). The LPA resides in both the common service area(CSA) and the extended CSA (ECSA).4. Finally, if the module is not in the LPA, ProgramManagement issues a directory search against the LNKLSTlibraries to find the location of the module.If Program Management locates the requested module in theJPA or the LPA, it does not need to load the module from DASD.If it locates the module in the JOB/STEP/TASK or LNKLSTlibraries, Program Management issues a fetch request to read theload module and prepare it for execution. If ProgramManagement cannot find the requested load module, theprogram load fails.This method of loading modules is inefficient if z/OS mustrepeatedly load the same modules from DASD. You can createcloned copies of frequently accessed libraries to try to reduceDASD I/O. However, the clone libraries also reside on DASDvolumes; therefore they do not reduce the amount of DASD I/Othat is required to load modules. They just spread the I/O outacross several volumes and paths. Additionally, clone librariesrequire extra time and attention for maintenance. This can be acostly solution, often requiring the purchase of additional DASDvolumes and other I/O hardware resources, such as controllersand channels.1–2 Getting Started

What Unicenter CA-QuickFetch DoesPlacing modules in the LPA can help reduce the I/O problemsomewhat; however, it can only maintain reentrant loadmodules. In addition, if you increase the size of the LPA to holdthe load modules, you reduce the amount of virtual storage thatis available for other processing. Storing modules in the JPA canhelp users who repeatedly request a small set of load modules.However, this only partially alleviates the problem because ofthe strict rules for sharing and reusing modules in the JPA. Inaddition, if other users access the same load modules, themodules have to be repeatedly read from DASD, because oneuser cannot access the JPA of another user.Many system-related programs, such as compilers, sortprograms, and TSO command processors are repeatedly loadedfrom DASD. Often, Program Management has to search severalDASD volumes to locate these programs. Also, mostapplications require the execution of several load modules.Program Management must search for each load moduleindividually. If Program Management must read several of theload modules from DASD, there will be considerable delays.Product Overview 1–3

What Unicenter CA-QuickFetch DoesProgram Loading Without Unicenter CA-QuickFetchThe following illustration shows the amount of I/O that isassociated with fetching load modules from DASD. WithoutUnicenter CA-QuickFetch, program loading requires a largeamount of DASD I/O.1–4 Getting Started

What Unicenter CA-QuickFetch DoesProgram Loading With Unicenter CA-QuickFetchUnicenter CA-QuickFetch eliminates much of the DASD I/Oassociated with program loading. It automatically determineswhat libraries to manage, determines the most frequentlyrequested load modules from these libraries, and maintainscopies of the modules in its own virtual storage area. Whenz/OS receives a request to load one of these modules, UnicenterCA-QuickFetch intercepts the request and satisfies it by movingthe load module from its virtual storage area to the addressspace of the requestor. This “virtual-to-virtual” transfer of loadmodules is faster and more efficient than loading a module fromDASD.As illustrated below, Unicenter CA-QuickFetch significantlyreduces or eliminates the DASD I/O that is associated withprogram loading. With Unicenter CA-QuickFetch, in-storageprogram loads replace most of the DASD I/O.ControllerProduct Overview 1–5

Unicenter CA-QuickFetch and z/OS TerminologyUnicenter CA-QuickFetch and z/OS TerminologyTo understand how Unicenter CA-QuickFetch works, youshould be familiar with certain Unicenter CA-QuickFetch andz/OS terminology.TermBLDLLNKLST libraryPrivate LibraryProgram FetchExplanationOn z/OS systems, a Build List (BLDL) macro instructioninitiates PDS directory searches to determine the location of arequested load module. If the directory search for a module issuccessful, the BLDL macro instruction returns the directoryentry of the module. Program fetch uses this information todetermine the location of the module on DASD.A partitioned data set (or a concatenation of a partitioned dataset) that everyone on the system may use. LNKLST librariescontain operating system programs, compilers, TSO commandprocessors, and other programs that many users would access.When the operating system initializes, the LNKLST is definedas the default location for these programs. Specifically, theLNKLST is the default location for the non-resident programload modules.Any PDS that is not part of the LNKLST concatenation.Unicenter CA-QuickFetch also considers any LNKLST libraryaccessed outside of the LNKLST concatenation (for instance, aJOB/STEP/TASK concatenation) to be a private library. Privatelibraries may contain load modules or non-load modules. Theycontain members that individual users create, edit, move, copy,and delete.The service that the z/OS Program Management uses to load amodule from DASD. The input to program fetch includes theoutput of a BLDL request (which contains the location of themodule on DASD).1–6 Getting Started

Because UnicenterCA-QuickFetch increases the efficiency of your system, itprolongs the time that your system is useful, allowing you todefer hardware upgrades. It also saves money because it allowsyour users to be more productive, obtaining better responsetime. Unicenter CA-QuickFetch provides the following benefitsto your z/OS system:■■■■■■Decreased I/O to DASD with libraries. This allows you toallocate your I/O resources to other system functions, suchas paging and data base access, which might be impairingthe performance of your system.Reduced I/O to critical system libraries.Decreased busy time for certain channels, control units,head-of-strings, and DASD volumes.Reduced program loading from your hardware cache. Thisallows you to devote the hardware cache to other types ofI/O.Reduced virtual storage constraints. This occurs when youremove the program load modules from the Link Pack Area(LPA), and manage them with Unicenter CA-QuickFetchand another Computer Associates product, Unicenter®CA-PMO Runtime Performance Optimizer (Unicenter®CA-PMO).Increased knowledge of program loading activity on yoursystem. Unicenter CA-QuickFetch provides you with onlinestatistics about fetch activity at the system, library, andmodule level.Product Overview 1–7

What Are the Advantages of Using Unicenter CA-QuickFetch?What Are the Advantages of Using UnicenterCA-QuickFetch?You can install Unicenter CA-QuickFetch quickly and easily. Itrequires no IPL or system modifications, and it calls for little orno operator training. In addition, it offers several advantagesover other methods of reducing DASD I/O due to program fetchactivity:■■■■■■Unicenter CA-QuickFetch works automatically with allcomponents of z/OS that generate fetch activity, not just asingle subsystem such as IMS. It works with all types ofprograms (reentrant, reusable, and nonreusable) to managestandard load libraries.Unicenter CA-QuickFetch automatically decides whatlibraries to manage so you spend no time tuning.Unicenter CA-QuickFetch automatically detects updatesafter module link-edits and purges the old versions of themodules from the virtual storage area. This allows newcopies of updated modules to be loaded into the UnicenterCA-QuickFetch storage areas.Unicenter CA-QuickFetch provides an AMASPZAPreplacement program that automatically communicates zapupdates to Unicenter CA-QuickFetch. UnicenterCA-QuickFetch can then purge the old versions of thezapped modules, and load the new versions when needed.You can run Unicenter CA-QuickFetch in multiple addressspaces. This eliminates the problem of having criticalapplications with different loading frequencies competingfor storage.Unicenter CA-QuickFetch supports clone libraries so you donot have to keep multiple copies of load modules in theUnicenter CA-QuickFetch virtual storage area.1–8 Getting Started

What Are the Features of Unicenter CA-QuickFetch?■■Unicenter CA-QuickFetch provides complete, reliable,automatic update detection. You can discontinue use of theLibrary Lookaside (LLA) for managing load modules.Unlike Library Lookaside, Unicenter CA-QuickFetch doesnot allocate a library with DISP=SHR the entire time that itis being managed. This allows for utilities, such as a librarycompress, to be performed without removing the libraryfrom management.What Are the Features of UnicenterCA-QuickFetch?Unicenter CA-QuickFetch offers the following features that helpreduce the amount of DASD I/O that is normally associatedwith program loading.The Unicenter CA-QuickFetch Virtual Storage AreaUnicenter CA-QuickFetch maintains its own virtual storage area.This area normally occupies one address space; however, youcan run multiple Unicenter CA-QuickFetch address spaces ifyou want to. For details on doing this, see Multiple AddressSpaces in this chapter.By default, Unicenter CA-QuickFetch manages all LNKLSTlibraries. In addition, it automatically determines which privatelibraries it should manage based on their loading activity. It thenuses a fetch activity list (see The Fetch Activity List in thischapter) to determine which modules from these libraries areaccessed most frequently. It can recognize modules with thesame name that are in different libraries. It maintains a copy ofthese modules in its virtual storage area. UnicenterCA-QuickFetch resolves requests for these modules bytransferring the modules from its own virtual storage to thevirtual storage of the program requestor.Product Overview 1–9

What Are the Features of Unicenter CA-QuickFetch?Automatic Library ManagementUnicenter CA-QuickFetch automatically determines whatlibraries to manage, so you do not have to spend timemaintaining a list of libraries. As soon as one module in a libraryhas enough activity to benefit from Unicenter CA-QuickFetch,Unicenter CA-QuickFetch begins managing the library. You canspecify particular libraries that Unicenter CA-QuickFetch may ormay not process, but this is optional.Protecting and Excluding MembersUnicenter CA-QuickFetch allows you to protect modules in thevirtual storage area. It also allows you to exclude members ofmanaged libraries from Unicenter CA-QuickFetch management.When you protect a module, Unicenter CA-QuickFetch will notdelete the module from the virtual storage area to make roomfor a module with heavier fetch activity. This is helpful if anapplication requires a large module but the module is notrequested often enough to remain loaded in the virtual storagearea. Loading the module repeatedly from DASD requiresconsiderable I/O. However, if the module remains loaded in thevirtual storage area, Unicenter CA-QuickFetch can load themodule more quickly when it is requested.You also can exclude members of a library that UnicenterCA-QuickFetch manages. When you exclude a module frommanagement, Unicenter CA-QuickFetch does not attempt toresolve fetch requests for that module.Product Overview 1–13

What Are the Features of Unicenter CA-QuickFetch?Support for Clone LibrariesUnicenter CA-QuickFetch efficiently manages clone libraries bymaintaining only one copy, in virtual storage, of modulesbelonging to clone libraries. After loading a module from a userspecifiedclone library into its virtual storage area, UnicenterCA-QuickFetch uses that copy of the module to satisfy fetchrequests for any modules with the same name from any userspecifiedclone library.Immediate Page-in for ModulesUnicenter CA-QuickFetch offers an immediate page-in feature forresolving fetch requests for modules that are larger than 8 KB.This is particularly beneficial for systems with limited centralstorage. When Unicenter CA-QuickFetch transfers a module, thepages containing the Unicenter CA-QuickFetch copy of themodule must be brought into central storage, unless they arealready there. Rather than waiting to access each page of themodule sequentially while transferring the module, UnicenterCA-QuickFetch uses the z/OS page service facilities toimmediately bring all pages of the module into central storage.Internal Monitoring of Virtual Storage UsageInternally, Unicenter CA-QuickFetch is constantly monitoringhow its virtual storage is being used to determine therequirements for loading modules into the virtual storage area.For each address space, Unicenter CA-QuickFetch checks theuser-specified maximum amount of virtual storage that isavailable and also checks to see how much virtual storage is inuse.1–14 Getting Started

What Are the Features of Unicenter CA-QuickFetch?If Unicenter CA-QuickFetch has ample storage, it continues toload modules as usual. However, if it determines that there isnot enough virtual storage in an address space, UnicenterCA-QuickFetch adjusts the requirements for loading modules inthat address space. If there is not enough virtual storage,Unicenter CA-QuickFetch requires that a module have morefetch requests before it is loaded. When the demand for storagelessens, Unicenter CA-QuickFetch lowers the requirements forloading modules.Unicenter CA-QuickFetch similarly monitors paging statistics(that is, current Unreferenced Interval Counter (UIC) values) onyour system and adjusts its initial loading criteria accordingly.When paging is high, more fetches are required to load amodule.A Monitor for Displaying Fetch StatisticsUnicenter CA-QuickFetch provides a monitor called QFMON,which allows you to see the information for fetch activity onyour system. QFMON consists of several different displays. Youcan execute QFMON under TSO, Advantage CA-Roscoe®Interactive Environment (Advantage CA-Roscoe®), or as abatch job. QFMON informs you of how often UnicenterCA-QuickFetch is resolving fetch requests, how much virtualstorage is being used, the size of the fetch activity list, whichlibraries Unicenter CA-QuickFetch is managing, performanceand cost savings during the peak and current intervals, and soon. There are separate displays for each UnicenterCA-QuickFetch address space. You can use the information onthe QFMON displays to determine how to tune UnicenterCA-QuickFetch to best meet the needs of your site.Note: Monitor statistics are only available while UnicenterCA-QuickFetch is active, since storage used to hold the statisticaldata is freed at Unicenter CA-QuickFetch termination.Product Overview 1–15

Installing Unicenter CA-QuickFetchInstalling Unicenter CA-QuickFetchComplete the steps on the following pages to install UnicenterCA-QuickFetch on your operating system.Step 1: Copy the QF.CNTL Library from the TapeThe installation tape contains a library named QF.CNTL. Thislibrary contains all of the JCL members that you will need toinstall Unicenter CA-QuickFetch. To copy QF.CNTL from thedistribution tape, create and submit an IEBCOPY job like the oneshown below://name JOB job statement//STEP1 EXEC PGM=IEBCOPY//SYSPRINT DD SYSOUT=A//SYSUT1 DD DSN=QF.CNTL,DISP=OLD,// UNIT=TAPE,VOL=SER=QFS260//SYSUT2 DD DSN=QF.CNTL,DISP=(NEW,CATLG),// UNIT=uuuu,VOL=SER=xxxxxx,// DCB=(RECFM=FB,LRECL=80,BLKSIZE=6160),// SPACE=(TRK,(6,2,10))//SYSUT3 DD UNIT=SYSDA,SPACE=(TRK,(10,10))//SYSUT4 DD UNIT=SYSDA,SPACE=(TRK,(10,10))//SYSIN DD *COPY INDD=SYSUT1,OUTDD=SYSUT2//Once you have copied the QF.CNTL library, you should save itsmembers for future Unicenter CA-QuickFetch maintenance.Note: You can use the exact JCL that is shown above. However,you have to supply your own job statement on the first line ofcode, where the words job statement are shown in italics. Youalso have to supply the appropriate unit information for uuuu,and volume information for xxxxxx.Before you proceed to the next step, examine the Readme file ofthe QF.CNTL data set. This Readme contains pending updatesto Unicenter CA-QuickFetch documentation, installation tips,and so on.3–2 Getting Started

Installing Unicenter CA-QuickFetchStep 3: Install the ManualsUnicenter CA-QuickFetch manuals are provided in the AdobePortable Document Format (PDF).You can view and print the PDF files using the Adobe AcrobatReader software. The Acrobat Reader, available for mostplatforms, is freely and easily available from www.adobe.com.When downloading the Reader, check the “with Search” option,which lets you perform searches across multiple books if asearch index (.pdx file) is provided.Note: To obtain a hardcopy of the manuals, print the PDF files.Installing and Printing the Manuals in PDF FormatThe PDF files are packaged on the tape as a compressed archivefile with a TGZ file extension. In addition to the PDF files, the.TGZ file contains a .PDX file and associated subdirectories forcross-book searching capabilities.To install and print the PDF files, follow this procedure:1. Use the PDFCOPY member found in QF.CNTL to unloadthe Unicenter CA-QuickFetch PDF data. The job copies theQF.TGZ file from the distribution tape.2. Move the compressed archive file to a platform thatsupports the Adobe Acrobat Reader.Use a binary file transfer program and download thecompressed archive file to the target platform. Retain the.TGZ file extension when downloading.3–4 Getting Started

Installing Unicenter CA-QuickFetch3. Restore the PDF files and directory structure.Uncompress the archive file on the target platform.On Windows 9x: Use a Windows decompression utility.Note: If using WinZip, use Version 7.0 or above.On Windows NT and 2000: Use a decompression utility:■■If using WinZip, use WinZip Version 7.0 or above.If using gzip, enter the following at a command prompt:gzip -d archivename.tgzpax -r -f archivename.tarNote: gzip is a non-standard utility freely and easilyavailable fromhttp://www.gnu.org/software/gzip/gzip.html. Thepax (Portable Archive Interchange) utility is standard.Save the restored files to the drive and directory of yourchoice.On UNIX (including z/OS USS and Linux), use one of thefollowing sets of commands:■gzip –d archivename.tgzpax –r –f archivename.tarNote: gzip is a non-standard utility freely and easilyavailable fromhttp://www.gnu.org/software/gzip/gzip.html. Thepax (Portable Archive Interchange) utility is standard.■uncompress archivename.tar.ztar xvf archivename.tarMove the files to the drive and directory of your choice.4. Start Acrobat Reader to view or print the PDF files.Installation 3–5

Installing Unicenter CA-QuickFetchStep 4: Remove Load Modules from LLA Management (Optional)Since LLA uses the Virtual Lookaside Facility (VLF) to managefrequently requested load modules in a data space, you shouldavoid using Library Lookaside (LLA) to manage any modulesthat Unicenter CA-QuickFetch is managing. Once LLA transfersa module to the VLF data space, Unicenter CA-QuickFetch doesnot receive fetch requests for that module.You can use one of two methods to remove load modules fromthe management of LLA:1. Remove the CLASS control statement that defines LLA toVLF from the COFVLFxx parmlib member. Look for thefollowing CLASS control statement:CLASS NAME(CSVLLA)EMAJ(LLA)VLF processes the COFVLFxx member at startup; therefore,this member resides in the parmlib that you specified on the//IEFPARM DD statement in the VLF startup procedure.2. If LLA is the only z/OS component that uses VLF, you candisable VLF using the following command:P VLFIf other z/OS components (such as TSO/E for CLISTS) useVLF, you cannot disable VLF.You can continue to use LLA to manage your library directories.If you do, you will see the following message shortly afterstartup:CSV231E LIBRARY LOOKASIDE IS NOT USING VLF. LLACANNOT DEFINE ITS VLF CLASS.RC=xxxxxxxx,RS=xxxxxxxx.You also can use the Unicenter CA-PMO product to manageyour library directories and reduce the DASD I/O caused bydirectory searches. Unicenter CA-PMO automatically detectssame-system and cross-system update activity and refreshes itsin-storage directories. LLA requires you to issue the refreshoperator command for an update to take effect.3–6 Getting Started

Installing Unicenter CA-QuickFetchIf you use Unicenter CA-PMO with Unicenter CA-QuickFetch,the Unicenter CA-PMO cross-system component willcommunicate zap updates detected by the UnicenterCA-QuickFetch AMASPZAP replacement program to UnicenterCA-QuickFetch address spaces running on other systems inyour complex.For more information about using LLA or Unicenter CA-PMO tomanage your library directories, see Using LLA to Manage YourLibrary Directories in the chapter “Tuning for Optimum SystemPerformance” in the Unicenter CA-QuickFetch SystemsProgrammer Guide.Step 5: Install the AMASPZAP Replacement Program (Optional)Unicenter CA-QuickFetch provides an AMASPZAP replacementprogram that communicates zap updates to UnicenterCA-QuickFetch. This program links to the IBM AMASPZAPprogram to perform the zap update, then reads the control cardsfrom the SYSIN ddname to determine which modules have beenupdated.The AMASPZAP replacement program communicates theupdates to all Unicenter CA-QuickFetch address spaces runningon the system. If you run the Unicenter CA-PMO product, itscross-system component will communicate the zap updates toUnicenter CA-QuickFetch address spaces on all systems in yourcomplex.When Unicenter CA-QuickFetch determines that a module hasbeen updated, it purges the old version of the module, andallows the new version to be loaded when it is needed.The fact that the Unicenter CA-QuickFetch AMASPZAPreplacement program is installed is invisible to users. Users thatperform zap updates should continue to execute theAMASPZAP program, since Unicenter CA-QuickFetch names itsversion of the program AMASPZAP and you rename the IBMversion.Installation 3–7

Installing Unicenter CA-QuickFetchTo install the AMASPZAP replacement program, follow thisprocedure for a non SMP/E installation of UnicenterCA-QuickFetch:1. Edit the JCL in member QFSSPZAP, follow the directions inthe member, and then submit the job for execution.2. Rename the IBM AMASPZAP program to the name youspecified in the QFSSPZAP job.If, at any time, you change the name of the IBM AMASPZAPprogram from the name you specified in the QFSSPZAP job,you must rerun the job with the new name.3. Copy the QFSSPZAP load module from your UnicenterCA-QuickFetch load library to the same LNKLST librarycontaining the IBM AMASPZAP program. Name the copiedmodule AMASPZAP.4. If you have aliases for the IBM AMASPZAP program, makethem aliases for the Unicenter CA-QuickFetch replacementversion by editing JCL member ALSSPZAP. Follow thedirections in the member, and then submit the job forexecution.To install the AMASPZAP replacement program, follow thisprocedure for an SMP/E installation of UnicenterCA-QuickFetch:1. Install Unicenter CA-QuickFetch into the LNKLIST if it isnot currently a LNKLST library. The UnicenterCA-QuickFetch load library must be located afterSYS1.MIGLIB, where the IBM AMASPZAP resides.2. Receive and apply USERMOD UMQFZAP to the UnicenterCA-QuickFetch CSI. Member SMPUMOD1 in the QF.CNTLlibrary may be used for this. This USERMOD adds theAMASPZAP alias for QFSSPZAP.3. Receive and apply the USERMOD to rename AMASPZAP tothe IBM CSI. The QF.CNTL member SMPUMOD2 contains asample for this. Change the USERMOD name to fit yourIBM CSI standards. If the operating system (OS) release levelis upgraded, all that is required is to re-apply thisUSERMOD.3–8 Getting Started

Installing Unicenter CA-QuickFetch4. If you are not going to rename AMASPZAP to the defaultname of MVSSPZAP, you must apply the USERMODcontained in QF.CNTL member SMPUMOD3.Note: You cannot put the Unicenter CA-QuickFetchAMASPZAP replacement program into LPA since it is notreentrant. You may leave the IBM AMASPZAP program in LPA;however, all aliases for AMASPZAP must be moved to theLNKLST library with the Unicenter CA-QuickFetch replacementprogram.Step 6: Specify ParametersThe QFPARMS member of QF.CNTL, which you copied fromthe installation tape, contains a list of the UnicenterCA-QuickFetch parameters and their default values. You canedit the default values to meet the needs of your site.As an alternative to using the QFPARMS member, you canspecify your Unicenter CA-QuickFetch parameters in anymember of your system PARMLIB, or in any sequential data setwhere LRECL has a value of 80 and the BLKSIZE has a valuethat is a multiple of 80. If you are going to use a different dataset for your parameters, keep in mind that the UnicenterCA-QuickFetch start-up procedure (explained later in thischapter) assumes that your parameters are in the QFPARMSmember of QF.CNTL.Note: Your parameter data set, whether it is QFPARMS oranother data set, can be shared by the same release of UnicenterCA-QuickFetch running on different systems.The parameters that you need to specify during installation areexplained on the next few pages. The names of parameters andtheir values are shown in uppercase. Terms shown in lower ormixed case represent variables for which you must specify avalue.Installation 3–9

Installing Unicenter CA-QuickFetchFor now, run only one Unicenter CA-QuickFetch address space.Also, use the supplied default values for the virtual storageavailable (MSLIMIT), the size ranges for the modules thatUnicenter CA-QuickFetch manages (MODLIMIT), and the sizeof the fetch activity list (MLSIZE). You will change these valueswhen you tune Unicenter CA-QuickFetch. For more information,see the Unicenter CA-QuickFetch Systems Programmer Guide.Parameter SyntaxFollow the general rules, shown below, for creating parameterentries.Each parameter entry consists of one or more parameters and anappropriate value for each. Parameter entries begin in column 1and can continue through column 71.ColumnContents1-4 One of the following:5 A blank.■■■A four-character SMF system ID indicates thatthis statement is valid for a particular system.Blanks indicate that this statement applies to allsystems.An asterisk (*) in column 1 indicates that thestatement is to be treated as a comment.3–10 Getting Started

Installing Unicenter CA-QuickFetchColumnContents6-71 One or more parameters and their values. For eachline in the data set, start the parameter statementsin column 6. Construct the parameter entry in thefollowing way:■■■■■Separate each parameter and its value with anequals sign (=); that is, parameter=value.If an entry contains more than one parameter,separate them from each other with a comma.If a parameter has options that do not take avalue, separate the option with a comma.Do not use blank spaces. UnicenterCA-QuickFetch stops reading a statement whenit encounters a blank space. Any informationfollowing the blank is treated as a comment.Make sure that each line contains a completeparameter statement. Do not continue aparameter entry from one line to the next. Ifyou have to start a parameter entry on a newline, always begin in column 6.72 A blank. Each parameter statement must end with ablank space.A few sample parameter statements are shown below. The firsttwo statements apply to particular systems; the rest apply to allsystems.CPU1 EXCPCOST=1.25CPU2 EXCPCOST=1.50INCLPRVT=CIC.PROD.LOADLIBMSLIMIT=750ID=AINCLPRVT=PRODLIB.LOADNUMINEL=30ID=BINCLPRVT=RESLIB.LOADNUMADDED=300INCLAUTO=USRVK11.*Installation 3–11

Installing Unicenter CA-QuickFetchParameters to Specify at Installation TimeFor a detailed explanation of the Unicenter CA-QuickFetchparameters, see the chapter “Using Parameters” in the UnicenterCA-QuickFetch Systems Programmer Guide. There are sevendifferent groups of parameters that you should specify whenyou install Unicenter CA-QuickFetch. You can specify theparameters in any order.1. The first set of parameters is for EXCP costs. Specify thefollowing parameters:EXCPCOST=monetary costMONEYSYM=monetary symbol2. By default, Unicenter CA-QuickFetch runs in an activemode. You will normally want to use this default:MODE=ACTIVEHowever, if you want Unicenter CA-QuickFetch to run in apassive mode, specify the parameter like this:MODE=PASSIVE3. The next set of parameters address the compatibility ofUnicenter CA-QuickFetch with other products. If you useAdvantage CA-Roscoe, JES3, or AllFusion CA-Panexec®,specify the appropriate values for one or more of theparameters listed below. For more information aboutcompatibility among these products, as well as informationabout BrightStor CA-PDSMAN® PDS LibraryManagement (BrightStor CA-PDSMAN®) and eTrustCA-ACF2® Security for z/OS and OS/390 (eTrustCA-ACF2®), see the chapter “Compatibility with OtherProducts” in the Unicenter CA-QuickFetch SystemsProgrammer Guide.PANEXEC=co-exist optionUSERSVC=SVC numberROSCOE=co-exist optionJES3ALLC=allocation option4. By default, Unicenter CA-QuickFetch automatically decideswhat private libraries to manage. If you wish, you canrestrict the Unicenter CA-QuickFetch management ofprivate libraries by specifying the INCLAUTO orEXCLAUTO parameters.3–12 Getting Started

Installing Unicenter CA-QuickFetchThe EXCLAUTO parameter prohibits UnicenterCA-QuickFetch from managing certain libraries:EXCLAUTO=data set name,VOL=volserThe INCLAUTO parameter defines a set of private librariesthat Unicenter CA-QuickFetch can manage automatically:INCLAUTO=data set name,VOL=volserIf you allow libraries with zap updates (including thosedone with SMP/E) to be eligible for management, make surethat you have installed the Unicenter CA-QuickFetchAMASPZAP replacement program (see Step 5: Install theAMASPZAP Replacement Program in this chapter). If suchlibraries are used on multiple systems in your complex, usethe cross-system component of the Unicenter CA-PMOproduct to communicate these updates to UnicenterCA-QuickFetch address spaces on other systems.Note: Specify either INCLAUTO or EXCLAUTO, not bothof them.5. If you have a severe paging problem on your system, youmay want to prevent Unicenter CA-QuickFetch fromautomatically selecting any private libraries formanagement. If this is the case, specify:EXCLAUTO=*If you specify EXCLAUTO=*, you must specify what privatelibraries Unicenter CA-QuickFetch will manage withINCLPRVT parameter statements:INCLPRVT=data set nameIn the future, if you want Unicenter CA-QuickFetch tomanage additional libraries, see the UnicenterCA-QuickFetch Q7 display. This display provides a list ofineligible libraries that you can make eligible formanagement using the INCLPRVT parameter or command.6. If you used the INCLPRVT parameter to specify privatelibraries that you want Unicenter CA-QuickFetch to manage,you can select for management, exclude from management,or both, particular members of those libraries. Use thefollowing parameters:SMEM=(selected members)Installation 3–13

Installing Unicenter CA-QuickFetchEMEM=(excluded members)7. Specify a user SVC number where Unicenter CA-QuickFetchcan place its user SVC routine if any of the following aretrue:— Unicenter CA-QuickFetch is coexisting with AllFusionCA-Panexec or eTrust CA-ACF2.— You have installed the Unicenter CA-QuickFetchAMASPZAP replacement program.— You have Extended Debugging Controller® (XDC/SE®,Copyright © 2000, Cole Software, LLC) running on yoursystem.Specify the parameter like this:USERSVC=SVC numberNote: Specify a user SVC if you are running multipleUnicenter CA-QuickFetch address spaces, but run only oneaddress space at this point.Step 7: License Unicenter CA-QuickFetch For Your SiteAuthorization for use of Unicenter CA-QuickFetch is performedthrough the Computer Associates License Management Program(LMP) facility of the CAIRIM component. CAIRIM is installed asa part of CCS for z/OS and OS/390.You must install CAIRIM, activate LMP, and code LMPstatements. For more information, see Specifying the LMP Codein the chapter “Preparing for Installation” and the CCS for z/OSand OS/390 documentation.Step 8: Install the QFMON ISPF PanelTo use the QFMON split-screen mode under ISPF, copy memberQFSPANEL from the QF.CNTL data set to one of the panellibraries concatenated to your ISPPLIB ddname.3–14 Getting Started

Installing Unicenter CA-QuickFetchStep 9: Edit and Copy the Startup ProcedureFollow these steps to edit and copy the UnicenterCA-QuickFetch startup procedure:1. Edit the startup procedure in the PROCQF member ofQF.CNTL. Follow the instructions within that member. Asample version of the PROCQF member is shown below://QFETCH PROC//*//* QF.CNTL(PROCQF)//* SAMPLE QUICK-FETCH STARTUP JCL.//*//* BEFORE USING -//* (1) CALCULATE THE REGION SIZE REQUIRED FOR QUICK-FETCH//* VIRTUAL STORAGE NEEDED = MSLIMIT + (20% MSLIMIT) + 250K//* SUPPLY THIS VIRTUAL STORAGE VALUE FOR THE REGION//* SIZE ON THE QFETCH EXEC STATEMENT.//* (2) SUPPLY THE QUICK-FETCH LOAD MODULE LIBRARY//* DSN FOR THE STEPLIB DD STATEMENT.//* (3) TAILOR THE QFPARM DD TO SUIT YOUR NEEDS.//* (SEE THE QUICK-FETCH SYSTEMS PROGRAMMER GUIDE).//* (4) COPY THIS PROC TO THE APPROPRIATE PROCLIB//* AS NEWNAME QFETCH.//*//QFETCH EXEC PGM=QFETCH,REGION=NNNNK,TIME=1440//STEPLIB DD DSN=CAI.QF.LOADLIB,DISP=SHR//QFSPARM DD DSN=QF.CNTL(QFPARMS),DISP=SHR//SYSUDUMP DD SYSOUT=A2. After editing the PROCQF member, copy it to the PROCLIBlibrary of your system. Use the name QFETCH forsimplicity. However, you can select any valid procedurename.3. Once you have copied the startup procedure, start and tuneUnicenter CA-QuickFetch. For details, see the UnicenterCA-QuickFetch Systems Programmer Guide.Step 10: Set Up the Advantage CA-Roscoe Interface (Optional)To allow Advantage CA-Roscoe users to use QFMON, followthe instructions in the QF.CNTL member INSTROSC.Installation 3–15

Going on From HereGoing on From HereIf you completed the instructions in this chapter, you haveinstalled and test-started Unicenter CA-QuickFetch.Take time to become familiar with Unicenter CA-QuickFetchand the QFMON displays. See the chapter “Monitoring FetchActivity with QFMON” in the Unicenter CA-QuickFetch SystemsProgrammer Guide. If you have allowed even a few of yourcritical libraries to be eligible for Unicenter CA-QuickFetchmanagement, you should see a significant improvement insystem performance. To ensure that Unicenter CA-QuickFetch isoptimizing program loading on your system, however, you willneed to make some tuning adjustments. Make these adjustmentsas soon as possible after you have installed UnicenterCA-QuickFetch.After you are familiar with Unicenter CA-QuickFetch, continueon to the chapter “Tuning for Optimum System Performance” inthe Unicenter CA-QuickFetch Systems Programmer Guide. Thischapter provides the information that you need to tuneUnicenter CA-QuickFetch to achieve optimum systemperformance. You will make adjustments such as selectingadditional libraries and modules for Unicenter CA-QuickFetchmanagement, determining the appropriate size for your fetchactivity list, and providing Unicenter CA-QuickFetch withenough virtual storage.In addition, that chapter also addresses special tuning concernssuch as handling competing applications, protecting andexcluding modules, minimizing paging problems, runningmultiple address spaces, and using LLA to manage your librarydirectories while Unicenter CA-QuickFetch is managing themodules.Installation 3–17
