IXGINVNT: Managing the LOGR policy

The IXGINVNT service allows your application program to manage and update the LOGR policy dynamically. You can also use the IXCMIAPU utility to manage the LOGR policy (see z/OS MVS Setting Up a Sysplex). The reason and return codes for both the IXGINVNT service and the IXCMIAPU utility are documented with the reference information on the IXGINVNT service in z/OS MVS Programming: Assembler Services Reference IAR-XCT.

For guidance on specifying information in the LOGR couple data set using IXGINVNT or IXCMIAPU, see the system logger chapter of z/OS MVS Setting Up a Sysplex.

Using IXGINVNT, your application program can:

Define and update log streams definitions using REQUEST=DEFINE or REQUEST=UPDATE with TYPE=LOGSTREAM.
Define a coupling facility structure associated with a log stream using REQUEST=DEFINE with TYPE=STRUCTURE.
Delete log stream and coupling facility structure definitions using REQUEST=DELETE.
