Enabling single-sysplex mode

Edit online

Enable single-sysplex mode as the operational mode used in the OMEGAMON® enhanced 3270 user interface.

Before you begin

Review the following requirements and limitations:
  • In each sysplex member LPAR where OMEGAMON tasks are run, there must be at least one Data Retrieval Agent (DRA) agent configured and running.
  • If your site is running CICSplexes that are defined to span across multiple sysplexes, data attributes for certain OMEGAMON AI for CICS capabilities might be incorrect (for example, Service Level Analysis and CICSplex overview information).

For more information, see Monitoring a single sysplex.

About this task

To operate the OMEGAMON enhanced 3270 user interface in single-sysplex mode, you must enable the feature using the KOB_TOM_MODE parameter. By setting the KOB_TOM_MODE parameter to SYSPLEX, the MODE parameter is changed from the default value of CUA to SYSPLEX in the job step of the started task JCL for the enhanced 3270 user interface, which is shown in the following example:
//*logon
//E3270UI EXEC PGM=KOBGATW0,
//          REGION=&RGN,TIME=&TIM,MEMLIMIT=&MEMLIM,
//          PARM=('MODE=&MODE,APPL=&APPL,FOLD=&FOLD,UMAX=&UMAX',
//          'TIMEOUT=&TIMEOUT',
//          'MULTI=N',
//          'PROD=&PROD,FSCR=&FSCR,0M=&0M')
After you start or restart the address space, the following message in the JES system log indicates that single-sysplex mode is enabled:
OMV020I e3270UI is running in SYSPLEX Mode

Use the following procedure to enable single-sysplex mode in the enhanced 3270 user interface.

Procedure

  1. Perform the following steps using either of the following methods:
    • Using PARMGEN:
      1. Set parameter KOB_TOM_MODE to SYSPLEX.
      2. Run $PARSE.
    • Using Configuration Manager:
      1. Add parameter KOB_TOM_MODE set to SYSPLEX to the RTEDEF(KOB$PARM) or RTEDEF(KOB$lpar) member. (Create the member if it is not present.)
      2. Run the GENERATE action.
  2. Refresh your PROCLIB entries.
  3. Start or restart the address space. When the enhanced 3270 user interface address space is up, verify that the following message appears in the JES system log: 
    OMV020I  e3270UI is running in SYSPLEX Mode

What to do next

Log on to the OMEGAMON enhanced 3270 user interface, running in single-sysplex mode.
