1 z/osmf User Experience - z/osmf in a Sysplex Doug Henry U S Bank Doug.Henry@usbank.com (262) August 8, 2012 Session Number 11837

2 USBank Environment 6 Sysplexes Running z/os V1R13 4 Z196 s and 2 Z10 s 4 Test and 2 Production SYSPLEXS DR site is the same 6 SYSPLEXS on 3 Z10 s DR site is continuously mirrored for both DASD and TAPE We do a DR test every quarter (4 per year) 2

3 USBank and z/osmf First ordered z/osmf with z/os V1R12 Incident Log We already had Operlog, Logrec log stream, automatic dump dataset allocation, Sysplex DAE, and System REXX That left us with getting CIM and CEA running With z/os V1R13 we converted from Repository Mode to SAF Mode 3

4 Choices for z/osmf in a Sysplex z/osmf is designed to only run on one system in the sysplex at any point in time Option 1 Create additional z/osmf instances (I found this hard to follow) Option 2 Use Jython script to dynamically change WAS/OEM variables and start z/osmf on any system in the sysplex Naturally we picked Option 2 4

5 z/osmf in a Sysplex - Setup 1. Set up a dynamic VIPA 2. Prepare a shared zfs environment 3. Switching /etc and /var to the shared zfs 4. Dynamically update WAS/OEM for sysplex name and host name 5. Moving IBM WAS/OEM for z/osmf to another system in the same sysplex 6. Cloning z/osmf to another Sysplex CEATOOL Managing Incident Log 5

7 Prepare a shared zfs environment Create new sysplex level z/fs s In the following list you can see all required paths that must be changed for a shared zfs environment: 1. All files and subdirectories for IBM WebSphere Application Server OEM Edition for z/os in /var/zwebsphereoem 2. All files and subdirectories for IBM WebSphere Application Server OEM Edition for z/os in /etc/zwebsphereoem 3. All files and subdirectories for z/osmf in /var/zosmf/ 4. All files and subdirectories for z/osmf configuration files in /var/zosmf/data 5. All files and subdirectories for z/osmf in /etc/zosmf 7

9 9 Switching /etc and /var

10 Switching /etc and /var Overview In a sysplex /etc and /var are defined with symbolic links as : /etc -> $SYSNAME/etc /var -> $SYSNAME/var Define new symbolic links related to the SYSPLEX /etc/zwebsphereoem -> $SYSSYMA/&SYSPLEX/etc/zWebSphereOEM /var/zwebsphereoem -> $SYSSYMA/&SYSPLEX/var/zWebSphereOEM /etc/zosmf -> $SYSSYMA/&SYSPLEX/etc/zosmf /var/zosmf -> $SYSSYMA/&SYSPLEX/var/zosmf 10

19 A short overview of Jython that my script uses [ ] Brackets are x AD and x BD : introduce a block of code (1 or more statements) used with if, elif, else.. Indentations have meaning # is used for comment line indicator == is a equal comparison a = b is a basic assignment If x == 1: y = 2 z = 3 elif x == 2: y = 3 z = 4 else: y = 5 z = 6 19

25 25 Moving z/osmf to another system in sysplex

26 Moving IBM Z/OSMF to another system in the same sysplex Stop z/osmf on the current system P BBN7ACRS When it is down then issue the start command to the system that you want z/osmf to run on S BBN7ACR,JOBNAME=BBNS001,ENV=BBNBASE.BBNNODE.BBNS001 26

27 Cloning z/osmf to another Sysplex Method 1 27

28 Cloning z/osmf to another Sysplex We use FDRDSF to create flat files We also terse the WASOEM Config file because it so big Then use Tso Transmit / Receive to move files to another sysplex 28

37 Cloning z/osmf to another Sysplex Method 2 37

38 Cloning z/osmf to another Sysplex Approach: Cloning WAS/OEM Config and z/osmf sizudata to a volume that belongs to an IPL Set. Advantages : When you IPL you will have environment ready for z/osmf No manual steps after build set is ready Disadvantage : You will use more disk space for multiple copies (about 1100 Cylinders per IPL set) 38

39 Cloning z/osmf to another Sysplex We have build set of volumes on Tech and 3 IPL Sets per Sysplex Apply Maintenance to the build set Then clone from the build set to one of the IPL Sets IPL Tech system from IPL set we copied to. 39

40 Cloning z/osmf to another Sysplex Bring up z/osmf to let WASOEM be updated with maintenance Shutdown z/osmf Run service for z/osmf /usr/lpp/zosmf/v1r13/bin/izusetup.sh -file /etc/zosmf/izuconfig1.cfg service Copy WASOEM.CONFIG1and SIZUDATA back to build volumes Now future cloning will be ready to IPL without and further work 40

43 Reasons for z/osmf Site Wide Our Network Sysprogs want Configuration Assistant Incident Log Futures like Software Deployment, etc 43

44 44 CEATOOL Manage Incidents

45 CEATOOL (OA38812, UA65835) Delete multiple incidents at a time that satisfy criteria Delete the diagnostic data that is associated with the incidents that will be deleted. That is: error log, error log summary, operations log, the entry for the dump in the sysplex dump directory and optionally, the SVC dump dataset. The utility deletes only inactive incidents that are not associated with a problem number or tracking ID. 45

46 CEATOOL ceatool -vd,retpd=14,deletedump=no,preview=yes -v Activates verbose mode, which issues additional diagnostic messages -d Deletes inactive incidents that satisfy the specified criteria retpd=numberofdays Deletedump=yes/no Preview=yes/no 46
