Issue/Introduction

This article explains how the USERID that is used to start the Datacom STC be defined to RACF external security.

Resolution

The Datacom Multi-User  (MUF) USERID needs to be defined to RACF the same as done for any other started task, by using the RACF STARTED class.

In order for external security to work correctly in the Datacom MUF , the USERID cannot be defined with the TRUSTED or PRIVILEGED attributes.

If the started task USERID is DBMUF1, the definition could look like this:

RDEFINE STARTED DBMUF1.** DATA('DBMUF1 STC ID') DEFAULTUACC(NONE) UACC(NONE) -
   STDATA(USER(=MEMBER) GROUP(STCGROUP) TRUSTED(NO) PRIVILEGED(NO))

Then refresh the STARTED class:
SETROPTS RACLIST(STARTED) REFRESH

Note: The MUF USERID does not require an OMVS segment.

Additional Information

For more information on the RDEFINE command, refer to the IBM documentation ( Security Server RACF Command Language Reference).
