The IXCMOD macro allows an active cross-system coupling facility (XCF) member to change its status-checking interval. The member must have status monitoring established.

A typical use of IXCMOD is for the caller to change its interval in response to a change in the system's environment, such as a change in the failure detection interval. See z/OS MVS Programming: Sysplex Services Guide for further information.

When a member changes its status-checking interval through IXCMOD, XCF notifies other active members of the group through their group user-routines.
