Enabling multi-tenancy mode

Edit online

Enable multi-tenancy mode in the enhanced 3270 user interface.

About this task

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

Use the following procedure to enable multi-tenancy 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_MT_ENABLE to Y.
      2. Run $PARSE.
    • Using Configuration Manager:
      1. Add parameter KOB_MT_ENABLE set to Y to the RTEDEF(KOB$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 Multi-Tenancy Mode
