Event Management Best Practices › Maintenance Considerations

Maintenance Considerations

Event Management r11 is installed into the following different executable code locations:

• The traditional CNSMLOAD and CNSMPLD load libraries.
• Two separate zFS files mounted read-only or read-write as follows:
  • Read-only file that contains the executables, scripts, HTML, and Java class files.
  • Read-write mounted file that contains the system specific information such as Event Management log files for that system.

When a new service pack becomes available, to perform maintenance without disrupting the running system

1. Create a copy of the production read-only zFS mounted read-write on a service directory.

   Note: Ensure the SMP/E environment uses DDDEFs for the service mount point; otherwise the programs will be linked into the wrong libraries. This holds true for the non-zFS DDDEFs as well.

2. Once the DDDEFs are correct, run the pre-maintenance script (EMPREMT) to save your customizations. APPLY maintenance as usual.
3. Run the post-maintenance script (EMPOSTMT) to restore the customizations.
4. Once the EMPOSTMT script has completed, you should be able to:
   • Shut down the running product
   • Swap zFS files
   • Update your BPXPRMxx member to use the new zFS file for the next IPL
