Fields

IRLM Proc: The MVS jobname associated with the IRLM address space.
IRLM Subsys: The IRLM MVS subsystem name.
Cross Memory: OMEGAMON® XE for Db2 PE displays YES if IRLM is using cross memory services to communicate with the attached subsystems. NO is displayed if IRLM is using common storage (CSA/ECSA) for all locking requests. You can override this option at IRLM startup using the PC= parameter
Identifier: The IRLM identifier specified at startup.
Deadlock Time: The length of a local deadlock detection cycle, which is the number of seconds that will elapse before the IRLM will check for deadlocks on a single Db2 subsystem.
Deadlock Cycle: The number of local deadlock detection cycles that will elapse before the IRLM will perform a global deadlock check on all subsystems that are using that IRLM.
Maximum ECSA: The maximum amount of CSA/ECSA that IRLM can use if IRLMPC = NO. (See the Cross Memory field.)
Current Used ECSA: The amount of CSA/ECSA that IRLM is currently using.
High Water Mark ECSA: The largest amount of CSA/ECSA that IRLM has used since startup.
Current Percentage ECSA: The percentage of Maximum ECSA that IRLM is currently using.
Subsystems Sharing IRLM: The number of subsystems using the IRLM.
IRLM Internal Trace: The status of the internal trace (extremely high overhead). ON if the trace is turned on. OFF if the trace is turned off. This option is specified at IRLM startup using the ITRACE parameter.

Data sharing options:

XCF Group Name: The name of the cross-system coupling facility (XCF) group in which this IRLM belongs. This option is specified at IRLM startup using the GROUP= parameter.
Max Users: The maximum number of systems in the data sharing group. This option is specified at IRLM startup using the MAXUSRS= parameter. It is used to determine the size of each hash entry in the global lock structure.
