When you defined your Multi-User Facility (called MUF) in version 14.0, 15.0 or 15.1, you may have defined the SIMPLIFY_MODE value in the DBSYSID/DBSIDPR module to use YES (to enable Simplify mode) or NO (to disable Simplify features). You can see the current setting in the MUF startup, in the DB00905I message. For example, you might see this:
DB00905I - DIRECTORY (CXX) VERSION 15.0 (+14.0) LEVEL 1 DB SIMPLIFY YES SYSPLEX PLEXC1
If you want to test the MUF functionality using the other mode, or if you need to change this setting on a permanent basis, the process is very simple.
In order to make this change of Simplify Mode, you first need to reassemble your DBSIDPR module using the new value, then, with the MUF down, you would run a DBUTLTY job on the same LPAR as the MUF using this input:
//SYSIN DD *
CXXMAINT OPTION=ALTER,OPTION2=MATCHSID
/*
This function will alter the CXX to match what is in the DBSIDPR module. You should see two DB00905I messages in the DBUTLTY job - one showing the setting before the change, and then another showing the new value. It might look like this:
DB00905I - DIRECTORY (CXX) VERSION 15.0 (+14.0) LEVEL 1 DB SIMPLIFY YES SYSPLEX PLEXC1
DB00101I - STARTED JOB-DBUTSIMP NUMBER-54361 CXX=MY15MUF
DB00905I - DIRECTORY (CXX) VERSION 15.0 (+14.0) LEVEL 1 DB SIMPLIFY NO
When you start the MUF, you can verify that your SIMPLIFY_MODE value has been changed by viewing the DB00905I message there.
