Requirements for Starting Applications

Before you start applications, some requirements must be met.

User Profile Requirements

The CICS region started task used to run the TIBCO EMS Client for z/OS (CICS) must have a unique userid assigned by the RACF STARTED class or the ICHRIN03 started procedure table. The userid assigned must have a valid z/OS Unix security context, or OMVS segment, in both the userid profile and group profile. Alternatively, the BPX.DEFAULT.USER FACILITY class profile, or equivalent if RACF is not used, can provide the appropriate z/OS Unix security context. Before attempting to run TIBCO EMS Client for z/OS (CICS), you must have your z/OS security administrator verify proper setup.

Note: It is good practice that you do not establish resource limits within the OMVS segment of the userid. Instead, the values specified in BPXPRMxx must be used where possible. Additionally, you must avoid using UID 0 (superuser) in the OMVS segment of the userid assigned to the CICS region started task.

Case Sensitivity

TIBCO messaging applications are case sensitive. Any application program that uses TIBCO EMS Client for z/OS (CICS) API calls must use the correct case when specifying the API call.
