Sysplex Considerations

Keep in mind the following when using CA MIC in a sysplex:

• Users of CA Remote Console who use CA MIC to collect messages from external systems on local CA Remote Console sessions should specify SYSPLEX=NO on the RCSINIT statement to prevent duplicate messages from being displayed at the local RCS session.
• After implementing SYSPLEX, you may see duplicate messages from external systems on local consoles. To prevent this, change the MSCOPE parameter on the local console to 'local-system-id', or '*'.

  For example, if D C,* shows that MSCOPE=*ALL, and this console is receiving duplicate messages, then enter the following z/OS command:

  VARY console,MSCOPE=*
  

• We recommend you use CONSOLE NAMES on the CA MIC LINK and COLLECT commands, rather than CONSOLE IDs. In a SYSPLEX, the CONSOLE IDs (on each system) may change, depending on the startup order of the systems in the SYSPLEX, while CONSOLE NAMES remain constant.
• The GCMINIT REPLYLIMIT=(0000,9999) statement limits WTOR reply ID values in a CA MIC complex. If a GCMINIT REPLYLIMIT statement is found during startup in a sysplex environment, then the statement is ignored. Additionally, the REPLYLIMIT keyword is not shown in the D GCM INIT display.
