System Logger

We recommend that a DASDONLY log stream be defined for each CA Vtape Subsystem to hold internal logger data. An overview of the security requirements for setting up an IBM system logger log stream follows.

Before setting up policies for your installation with the IXCMIAPU Administrative Data Utility program, you must be authorized to use IXCMIAPU.

To define the CA Vtape Log Stream for each system, customize and run the IBM IXCMIAPU utility. Sample JCL is in member IXCMIAPU of the CA Vtape CCUUJCL data set.

We recommend that you set the IXCMIAPU HLQ parameter to the CA Vtape DSN prefix. If a different HLQ value is selected for the Log Stream, the CA Vtape security profile must be given CREATE access authority to the new HLQ. Other security-related steps may be required if the System Logger was never customized in your system.

Note: For more information about these steps and requirements, see the IBM guide z/OS MVS Assembler Services Guide. The following is a brief summary of these steps:

• IBM recommends that the System Logger address space (IXGLOGR) be assigned privileged security status to avoid giving the logger specific access rights to each Log Stream defined in the system.
• The LOGR policy information describes the characteristics of each log stream and coupling facility structure that will be used when there are active connections to the log stream.
• The CFRM policy contains the definition of all coupling facility structures used by system logger, if applicable.
• The users of the IXCMIAPU utility require authorization to the resources accessed by the utility. Define the appropriate authorizations before users try to add, update, delete, or extract a report from the LOGR policy.
• The LOGR couple data set must be activated and available before you add log streams and structure definitions to it.
