The IXGCNF=system parameter specifies one or more IXGCNFxx parmlib members to be used when system logger starts or is restarted on the initializing system within the sysplex.

The IXGCNFxx parmlib members contain statements that can be used to control the following functions:

1. Identify the tracing options when system logger initializes.
2. Specify the logger monitoring intervals for warning and action messages.
3. Specify the ZAI statement attributes for the z/OS® Advanced Workload Analysis Reporter (IBM zAware) log stream client socket communication and log data buffering details in order to send log stream data to the IBM zAware server.

Syntax IXGCNF=aa specifies a single member and syntax IXGCNF=(aa,bb,...) identifies groups of system logger initialization statements across several IXGCNFxx members. When multiple IXGCNFxx members are concatenated, the individual system logger options are merged with the last parmlib member option taking precedence.

If any errors are encountered for the specified IXGCNFxx parmlib members, logger will issue an error message and then attempt to process remaining parameters for syntax. For a SET IXGCNF command, parameter updates are not done. At IPL, default values are substituted for all parameters. For example, assume a shared IXGCNFxx parmlib includes the MONITOR LSPRIMARY,CONSUMPTIONALERT(value) specification. Also assume one release is at z/OS v1r13 and the other is at z/OS v2r1, The shared IXGCNFxx parmlib member will be honored on the z/OS v2r1 release. However, the z/OS v1r13 release processing will issue an unrecognized keyword type error message, and use the system defaults for all the IXGCNFxx options.

The DISPLAY LOGGER,IXGCNF[,options] command displays the merged information.
