The following features were added (or fixed) in the January 6th, 2022 build:

• 50089: Compatibility updates for 4.6 controllers

Upgrading to 4.5 is only recommended from the March 5th 2019 build of 4.3 (or newer) - upgrading from any other build or release will require manually recreating all WRKCSE, WRKCSEDTA and WRKCSECRDL entries. Use the following command to display the build date:

DSPDTAARA DTAARA(QZRDHASM/BUILD)

All the controllers and source LPARs in a cluster must be at the same version (i.e. 4.5). We strongly recommend that they also all be at the same build date. The version and build date is stored in data area QZRDHASM/BUILD.

The 4.5 controllers will support non-cluster source LPARs running at 4.3, 4.4 or 4.5, which facilitates upgrading source LPARs in stages.

1. Upgrade the controllers to the 3/5/2019 (or newer) build of 4.3
2. Ensure no SWCSE commands are in process.
3. End the toolkit subsystem:

   
   ENDSBS QZRDFSR *IMMED

4. Generate a text file with all of the WRKCSE / WRKCSEDTA information:

   
   QZRDHASM/DMPINF ENV(*ALL) EXTDLOGS(*NO)

5. Save the DDD information:

   
   MKDIR '/tmp/ddd43backups'
   QZRDHASM/SAVDDD PATH('/tmp/ddd43backups')

6. On each controller, issue the restore command:

   
   RSTLIB SAVLIB(QZRDHASM) DEV(*SAVF) SAVF(QGPL/QZRDHASM45) MBROPT(*ALL) ALWOBJDIF(*COMPATIBLE) OMITOBJ((QZRDHASM/*ALL *DTAQ))

7. Update to the most recent Secure Java jar file:
   Download it from here: https://sourceforge.net/projects/jsch/files/jsch.jar/0.1.55/jsch-0.1.55.jar/download
   Place it on all controllers in /QIBM/Qzrdhasm/ssh/
   Then update the links:

   RMVLNK OBJLNK('/QIBM/Qzrdhasm/jsch.jar') 
   ADDLNK NEWLNK('/QIBM/Qzrdhasm/ssh/jsch.jar') OBJ('/QIBM/Qzrdhasm/ssh/jsch-0.1.55.jar') 

8. On one controlling partition, migrate the existing DDD to the new format:

   
   CALL QZRDHASM/QZRDIAMIGW

9. On each controlling partition issue the setup command:

   
   SETUPFSR NODEROLE(*CTL)

10. Update job scheduler entries to call CLEANLOGS instead of CLNICSMLOG.
