ENQSYSTEMS Statement

ENQSYSTEMS Statement

The ENQSYSTEMS statement controls whether PowerExchange uses a scope of SYSTEM or SYSTEMS for ENQ macros that it issues to lock PowerExchange data sets and resources.
z/OS
ENQMAJORNAME
No
ENQSYSTEMS={
N
|Y}
  • N
    .
    PowerExchange uses a scope of SYSTEM on ENQ macros, which provides protection on the system on which the ENQ is issued.
  • Y.
    PowerExchange uses a scope of SYSTEMS on ENQ macros. To provide multisystems protection with these enqueues, you must use GRS or a similar product to propagate them to other systems.
    If you specify Y for the ENQSYSTEMS statement and you propagate enqueues to other z/OS systems that all use the same major name, you might experience contention for some PowerExchange resources.
Default is N.
By default, PowerExchange uses a major name of DETAIL. To change the major name, use the ENQMAJORNAME statement.
