BCV5 TMFAST AND EFFICIENTDB2 DATA MIGRATIONSCorporations maintain large amounts of data in DB2 databases, and it is normal to fi nd several DB2subsystems for production, test and development. Refreshing testbeds from production systems isa vital part of the development, testing and quality assurance life cycle. Obtaining relevant test datarequires copying from one DB2 subsystem to another. The window of opportunity for copying ormigrating DB2 data is constantly decreasing as the demands from 24x7 operations are increasing.Limited resources and shrinking batch windows make data delivery to QA diffi cult.CV5 quickly and effi ciently copies, refreshes andB replicates DB2 objects. BCV5 copies DB2 databasesor tables within the same or different DB2 systems. Whenmeasured against conventional copying methods, BCV5saves around 90% on elapsed copy time and resourcesconsumed (SSU, SRU). For one customer a ten-hourunload/load process was reduced to slightly over one hour.A BCV5 copy task integrates both the physical datamovement and the DDL related requirements. It copiesDB2 data, i.e. databases or tables with or without auxiliaryobjects – indexes, views, triggers, procs and runstats.BCV5 automatically handles the OBID translation and theRBA adaptation. Copy jobs are completed in minutesrather than hours. DBAs are no longer forced to wait forweekend time slots and are able to run copying jobs onregular weekday shifts. Test data on demand is a dreamcome true for QA, development and test staff. BCV5offers relief where the need is greatest. It signifi cantly cutsdown runtime and cost. It reduces CPU consumption by90%+ and shortens the preparation lead time requiredby the staff.Automation Reduces Manual Effort and Keystroke ErrorsBCV5 is a completely automated expert system. Theintegrated ISPF interface allows the copy process to beeasily defi ned. Specifying the select/exclude patternsidentifi es the objects to be copied and the appropriateprocessing options. BCV5’s powerful renames maskfacility makes adhering to naming conventions during thetarget DB2 system a simple and error free task. A BCV5copy process executes either under the control of theproduct or an in-house scheduler. Once the copy processis started there is nothing else to do. BCV5 automaticallygenerates the DDL for the selected objects/databases using the specifi ed target names. It executesthe DDL in the target DB2 environment, tailors the respectiveJCL and generates the required statements forthe copy utility. What if the target objects already exist?BCV5 still automates everything. It is an expert systemwith a comprehensive check facility that ensures that thetarget DB2 objects match the source objects. Structuraldifferences are detected and successful completion of thecopy process is guaranteed.Flexible Selection of Image CopiesBCV5 permits copying directly from tablespacesor a set of image copies. Its fl exibleselection facility allows choosing theimage copy (set) to copy from. Using thelatest, a specifi c generation or dated imagecopy is easy and straight forward. Itidentifi es the right image copy datasetsand pulls them into the copy process.1 | 5 © UBS Hainer distributed in the US and Canada by ESAi - Enterprise Systems Associates, Inc.Contact ESAI Contact at: 1-866-464-3724 ESAi at 1-866-GO-4-ESAi or sales@ESAIGroup.comor

BCV5 – FAST AND EFFICIENT DB2 DATA MIGRATIONSBenefits• Automates DB2 Cloning/Migrating/Refreshing• Saves 90% CPU resources and run time• Eliminates manual efforts freeing up technical staff• Reduces overtime work and manual intervention• Integrates seamlessly into IT environments• Eliminates RUNSTATS, Rebuild Index, etc.• Reduces DASD space required for direct copyingRUNSTATS Cost Time and MoneyDB2‘s optimizer needs valid RUNSTATS data to fi ndeffi cient access paths. The RUNSTATS utility is known asa long running CPU hog. BCV5 eliminates costly RUN-STATS executions. Its copy statistics feature extracts thecurrent RUNSTATS from the source environment and loadsthem into the target in seconds. It is no longer necessaryto wait for hours while RUNSTATS fi nishes running.Why is BCV5 so fast?BCV5 copies the data at the page level using a proprietaryhigh performance copy utilty. While the UNLOAD/LOADprocess slowly extracts single rows one at a time, BCV5copies the complete page over to thetarget and replaces the DB2-internalOBIDs with the respective target values.BCV5 also uses parallelism as a performanceenhancement technique. Itoperates in a multi-thread mode andcopies ten to eighteen tablespaces ortablespace partitions in parallel. Thisalone makes it up to ten times fasterthan DSN1COPY. One other performanceenhancement feature involvescopying indexspaces. Copying indexspacesis much faster than rebuildingthem.How can BCV5 save 90% CPU Time?Row-wise processing consumes many more CPU cyclesthan VSAM copying. Clients report that only one-fi fth toone-tenth of the service units used by Unload/Load arerequired to run BCV5. Add to these savings those resultingfrom avoiding index rebuilds and runstats executions.LOADs demand heavy DB2 subsystem resources. Theload job’s CPU consumption is reported in the job listing,but the very high service units used by DB2 is no normallytallied. The immense amount of data, that corporationsneed to maintain, demands the use of effi cient tools. It isnot longer feasible to waste time and service units needlessly.There is an added bonus for users with really largetables. BCV5 does not require storage for unloaded data.BVC5 copies data directly from the source pageset to thetarget pageset.Making the Copy Process EasyA fast and effi cient cloning tool is only part of the solution.The BCV5 user interface is intuitive and easily meetsthe needs of both experienced effi ciency-minded expertsand the less technical application level users. Those whoprefer the PC environment can use BCV5’s graphical workstation.Detailed online help is always one click away.Who needs BCV5?Cost savings are obviously appreciated by those whohave budget responsibility. Avoiding an expensive andonerous hardware upgrade can reduce the negativeimpact to an IT budget. The IBM andthird party software upgrade fees associatedwith getting a bigger machineoften dwarf the hardware cost. Applicationdevelopment teams, QA groups,technical support staff, auditors and,of course, end users need the data toget their jobs done.

BCV5 – FAST AND EFFICIENT DB2 DATA MIGRATIONS» BCV5 allows us to copy much moredata than we ever could have copiedwith our old LOAD based processes.This is great improvement for ourQA environments. «Features• Checks and/or generates DDL• Automates tasks for: OBID, RBA, LRSN, Grants, etc.• Flexible space allocation• Offers intuitive ISPF interface for easy management• Provides a batch interface to create large numbersof copies• Offers optional components for data reduction,data masking, and DDL structure analysisamount of weekend and off-shift time usually requiredfor the copy and refresh process. This allows more qualitywork to get completed during regular shift hours. Shopsrunning with reduced or less experienced staff are amongBCV5’s most vocal supporters. Getting the job done is,after all, the true mission of IT. When data is not available,the job does not get accomplished and the wholeorganization pays the price.A Quick View of BCV5BCV5 provides fast, effi cient and manageable copying ofDB2 data. It automatically generates and executes jobsto: • extract object defi nitions from the DB2 catalog ofthe source system, • transfer the defi nitions to the targetsystem, rename the objects as specifi ed and apply themin the target DB2 system (CREATE, or DROP and CREATE),• compare the source defi nitions with existing targetobjects for compatibility, • copy pagesets from source totarget DB2, • make target objects ready and start them.The product provides two user interfaces with identicalfunctions. One is based on ISPF and the other on a workstationGUI.To defi ne a copy task, select andd efi n e : • the DB2 subsystems, sourceand target which are identical if copyingwithin a single subsystem, • theobjects: databases or tables to becopied, • the renaming rules to thecopy objects, • whether the indexesare to be copied, • whether the relatedRUNSTATS should be transferred tothe target system catalog, • whetherother related objects (GRANTS,BINDS, VIEWS) should also be transferred,• whether the source objects should be put in"read only" mode during the copy, • whether BCV5 shouldbe used to avoid impacting the source objects. Once atask is defi ned it may be executed at any time underBCV5’s control or under the shop’s scheduler or manuallyon a stage by stage basis.User creates a copy task using ISPF or Workstation or Batch InterfaceSource DB2Extract meta data from DB2 CatalogSet objects ’read only’ optionoptionallyCopy Pagesets or ImagecopiesBCV5 – Task Definition and ExecutionTarget DB2Check, amend,add DDLMake objects readyand execute objectsBCV5 Workflow3 | 5 © UBS Hainer distributed in the US and Canada by ESAi - Enterprise Systems Associates, Inc.Contact ESAI Contact at: 1-866-464-3724 ESAi at 1-866-GO-4-ESAi or sales@ESAIGroup.comor

BCV5 – FAST AND EFFICIENT DB2 DATA MIGRATIONS» With BCV5 we have been able toreduce our batch processing cycleby 2 1/2 hours and are meeting ourSLA commitment for the reportingdatabase for the first time ever. «Optional ComponentsBCV6 – Consistent copying without impacting dataavailability. When data must come from tables thatrequire 24x7 enterprise availability there is an issue forIT. Users need to query and update the tables withoutinterruption. Stopping the source objects is not a viableoption. Without stopping the source objects, it can bevery diffi cult to copy tables while preserving consistencybetween tables and indexes and between different tables.BCV5 minimizes the copy time, but cannot avoid theimpact of changes made to objects while they are beingcopied. The good news is that DB2 stores informationabout all these table changes in its log. BCV5 is anautomated solution that uses the information in the logto bring the copied tablespace to a consistent state.Data Replication – Copy only a subset of your data.Why copy an entire table when a smaller and moremanageable subset will get the job done? Depending onthe test plan a full table copy may not be necessary. Ifa particular test scenario only requires customers froma certain zip code, for example, why copy an entiretable with thousands or millions of unwanted rows? Astables grow in size there is not always enough free spaceto hold multiple copies of test data. At times it is preferableto specify copy criteria for skipping rows prior to copyingor replicating them.required. Replacing the name and other sensitive informationwith random data is a typical requirement. Often itis essential to replace fi elds according to specifi c patternsso that the original data relationships can be maintainedfor parallel and integration testing.Archive Data – Archive DB2 data once and populatedifferent environments. Need to provide DB2 data fromlast week, last month or last year? Want an automatic andeffi cient procedure to recreate everything, DDL and datain record time? BCV5 Icebox (IB) takes fast snapshots ondemand or periodically, and restores the objects or databaseswhere/when needed using names specifi ed. Issuesof compatibility or completeness no longer cause concern.IB packages the DB2 Version x imagecopy and later restoresit to any other DB2 target version required. Upgradeto a newer version of DB2 knowing that former imagecopies will be still available for future needs.Data Management – Mask sensitive DB2 data at thesource. Organizations normally need to copy sensitive datafrom a production system to a testing or QA environment.In order to adhere to data privacy regulations and corporatesecurity, a signifi cant amount of extra processing is often4 | 5 © UBS Hainer distributed in the US and Canada by ESAi - Enterprise Systems Associates, Inc.Contact ESAI Contact at: 1-866-464-3724 ESAi at 1-866-GO-4-ESAi or sales@ESAIGroup.comor
