ENQMAJORNAME Statement

ENQMAJORNAME Statement

The ENQMAJORNAME statement specifies the major name for ENQ macros that PowerExchange issues to lock PowerExchange data sets and resources.
z/OS

No
ENQMAJORNAME={
major_name
|
DETAIL
}
For the
major_name
variable, enter the major name for ENQ macros that PowerExchange issues to lock PowerExchange data sets and resources, such as the PowerExchange message logs, capture registrations, and DB2 bulk load operations. Default is DETAIL.
  • By default, the scope of ENQ macros that PowerExchange issues is SYSTEM, which means PowerExchange locks data sets within a single system. To change the scope of the ENQ macros that PowerExchange issues to SYSTEMS, specify Y for the ENQSYSTEMS statement.
  • For data set locks, PowerExchange uses the data set name as the minor name in the ENQ macros.
  • For resource locks, PowerExchange uses minor names related to the resource.
    The following table lists the minor names that PowerExchange uses to protect resources:
