And a one, and a two… All together now! Enhanced Preventive Service Planning Tool BY KEVIN PETERS Have you ever been frustrated trying to determine not the recommended service, but the service needed to run a function within z/OS, particularly those which cross several components? Has the effort of determining whether you have service installed on your systems given you a headache? Well, the Enhanced Preventive Service Planning Tool (EPSPT) has been upgraded to help you with this problem! Overview of the EPSPT To make it easier for you to identify the maintenance that you need to order and install, IBM provides EPSPT, which was announced at SHARE 2004. The tool is located on the Web at: techsupport. services.ibm.com/390/psp_main.html. EPSPT provides you with an easy way to obtain service recommendations from a number of z/OS and z/OS related preventive service planning subsets — base z/OS components, CICS Transaction Server, DB2, IMS, MQSeries ® , WebSpere Application Server and IBM System z products. EPSPT also helps you quickly determine which of the service recommendations have already been applied or installed on a particular target zone in your system. The new stuff! In most subsets, the majority of service recommendations come from a single component with a few cross product dependencies. In some cases, however, IBM provides a function that spans multiple components. Some historic examples of cross component functions are “Sysplex DataSharing” and “YE2000”. The latest examples for which IBM has created functional service recommendation lists are the zSeries Application Assist Processor (zAAP) and IBM Health Checker for z/OS checks. We have also created an intra-component list for Global Resource Serialization Star. Note that these service recommendation lists are not in RETAIN ® . However, IBM is investigating whether to provide them through other service tools, such as ServiceLink. 48 February 2006 z/OS HOT TOPICS Newsletter, Issue 14 You can obtain the service recommendations for function lists through the EPSPT graphical user interface, as follows: 1. Select Find Bucket Extract Files. 2. Select By Category. 3. Select Function under Step 1 — Select Type. 4. Make selections for Steps 2 – 4. 5. Press Add to cart. 6. Click the item in cart link. 7. Select the bucket and press Download now to extract the file from the cart. As with previously supplied extract files, you can process the downloaded extract file with the EPSPT Host Tool to determine which service needs to be applied or installed. Other enhancements Previously, the extract files for RETAIN based PSP subsets only contained information from the service recommendation section. The new EPSPT information has been made more comprehensive. Now, all APARs and PTFs contained in each subset (and any extensions) are included in extract files. This is particularly beneficial for device related subsets that contain APARs and PTFs in the General Information section. Additionally, as of 12/07/2005, IBM TechSupport has merged the ability of researching PSP subsets and acquiring extract files; it is located on the Web at: http://www14.software.ibm.com/webapp/ set2/psp/srchBroker. In the near future, the support of EPSPT will be transitioned from the earlier mentioned site to this one. Notice that the search capability from the earlier site is located on the bottom of the new page.

Storage made easy Answers that won’t drive you nuts BY EDWARD BAKER AND SEAN MCMILLEN z/OS system programmers, z/OS storage administrators and independent software vendors are asking IBM some typical questions about storage. Let’s take a look: Dear IBM, I use tape mount management (TMM) heavily in my shop. This is in order to minimize the number of tape mounts and maximize the usage of my tape resources during tape mounts. I have noticed that these tape mount management data sets are not eligible for the fast subsequent migration (FSM) function. Is there anything that one can do to allow these data sets to be candidates for fast subsequent migration? Thanks, Mr. Tapemount Dear Mr. Tapemount, You are in luck; beginning in z/OS R7 we have implemented changes to fast subsequent migration that can solve your common dilemma. As you’re aware, fast subsequent migration is a function that allows data sets that have been recalled from migration level 2 (ML2) tape to be reconnected to the initial place of origin on that ML2 tape. This is only possible if the data set was not modified since being recalled. In a tape mount management (TMM) environment, data sets are normally assigned to a management class or storage group that does not require backup. You were most likely encountering this problem because no valid backup copy typically exists for data sets in a TMM environment. In z/OS V1R7, DFSMShsm, with assistance from other z/OS DFSMS components, developed a more rigorous FSM design that allows TMM-type data to be reconnected. In fact, even data sets without a valid backup copy are now eligible for fast subsequent migration as long as the data set remains unaltered since the recall. Let us know how this enhancement works for you! Thanks, IBMer To DFSMShsm Development, I utilize your HMIGRATE command daily. Typically, it’s when I am about to leave work and I want to migrate all my L0 volume data sets that I used that day. I migrate most of my data sets to ML1 DASD, or even sometimes ML2 tape. When I found out that I could use partially qualified data set names on the command with the use of filters (also known as wildcards) I was ecstatic. This allowed me to accomplish all migrations with a single command. Because I don’t reuse every single data set created every day, I often find that I get an annoying error message. The error message appears for every data set that meets the filter criteria that is already migrated. Is there a way to turn off notification of all these error messages? I really like using the HMIGRATE with wildcards (*). Thank you, Mrs. Migrate Dear Mrs. Migrate, We understand your request, and we have an answer for it beginning in DFSMShsm V1R7. We will no longer issue the ARC1224I message for data sets already migrated to ML1 when you use the HMIGRATE command with partially qualified data set names and filters. Additionally, you will no longer see the ARC1282I error message when the data set already resides on an ML2 tape volume. This eliminates the multitude of error messages that you receive during your migration processing. By the way, we also implemented the bypassing of error messages whether or not you specify the ML2 parameter on your HMIGRATE command. Try it out and let us know what you think. Thanks, HSM Development To IBM, We have recently invested in your latest high capacity tape media, the IBM TotalStorage® 3592 Tape Cartridges. I find it just phenomenal that you can put 300 GB of uncompressed data on a single tape these days. I remember back when the 3480s came out in 1984 and the capacity was 200 MB of data. Back in those days that was a whole lot of data (ha-ha!). Anyway, we have found that DFSMShsm has not been filling our larger tapes to their full capacity. We see this primarily when we place hundreds of thousands February 2006 z/OS HOT TOPICS Newsletter, Issue 14 49
