There is a hlq.CDBAPARM(MIGRATOR) parameter called TOLRMSGS. This parameter will enable a YES or NO flag which will either allow or disallow the generation of the messages.
TOLRMSGS indicates whether to create the RCMTOLR data set and populate it during analysis. If Y, the RCMTOLR data set is created and populated during analysis. Messages are written about each object that is not yet supported by CA RC/Migrator in the subsystem. This is the default.
If N, the RCMTOLR data set is not created.
The parameter can be found in the header of the MIGRATOR parmlib member and appears like this:
TOLRMSGS (YES) /* TURN TOLERATION MESSAGES ON
/* OR OFF. SPECIFY NO TO NOT
/* GENERATE THE MESSAGES/DATASET.
This parm can also be added to the MIGRATOR member via the EP(Edit Parmlib Members) function on the main menu.
When editing the MIGRATOR member using EP you will see "Generate toleration msgs?....> Y (Y/N)" as an option to set.
