Category 1 transactions
Category 1 transactions are never associated with a terminal. They are for CICS® internal use only, and must not be started from a user terminal. CICS checks that the region user ID has the authority to attach these transactions.
If the region user ID is not authorized to access all of the category
1 transactions, CICS issues
message DFHXS1113 and fails to initialize. For category 1
transactions, specify the following settings:
- To CICS
- RESSEC(NO) and CMDSEC(NO) on the transaction resource definition.
- To RACF®
- UACC(NONE) and AUDIT(FAILURES) in the corresponding transaction profiles. AUDIT(FAILURES) is the default value. The access list must contain only user IDs (or groups containing user IDs) that can be specified as CICS region user IDs.
RDEFINE GCICSTRN CICSCAT1 UACC(NONE)
ADDMEM(CSKP CSPQ CDBD . . . . . . . . CXRE CSNE)
NOTIFY(security_admin_userid)
OWNER(userid or groupid)
PERMIT CICSCAT1 CLASS(GCICSTRN) ID(cat1grp1,...,cat1grpz) ACCESS(READ)By defining these transactions to RACF with UACC(NONE) and an access list, you prevent any terminal user initiating these transactions (accidentally or otherwise). It is important, because starting these transactions at a terminal has unpredictable results. The sample CLIST DFH$CAT1 helps you define the category 1 profiles to RACF. The sample CLIST is in library CICSTS53.CICS.SDFHSAMP.
The table lists the category 1 transactions supported in CICS Transaction Server for z/OS®,
Version 5 Release 3:
- The transactions that have operator interfaces are marked by an asterisk (*). The other transactions have no operator interface.
- Transactions CGRP, CSSY, and CSTP are transaction names that are used by some CICS tasks.
- Transaction CPLT might run under a different user ID if the PLTPIUSR system initialization parameter is specified. For more information, see Post-initialization processing.
