IXLUSYNC processing requires that all active connections reach a sync point before proceeding. The performance of IXLUSYNC depends on the environment, the number of connections to the structure, and the processing required to reach the sync point. Also, depending on the protocols of connections during IXLUSYNC, the services provided by those connections may be temporarily unavailable.

IXLUSYNC processing might involve referencing or updating the CFRM active policy to reflect the operation that has been requested. When invoking this macro, be aware of the I/O to the CFRM couple data set that might be generated.
