z/OS®z/OS commands that operate on IRLM

You can use several z/OS commands to modify and monitor the IRLM connection.

MODIFY irlmproc,SET,PVT=nnn

Sets the maximum amount of private virtual (PVT) storage that this IRLM can use for lock control structures.

MODIFY irlmproc,SET,DEADLOCK=nnnn

Sets the time for the local deadlock detection cycle.

MODIFY irlmproc,SET,LTE=nnnn

Sets the number of LOCK HASH entries that this IRLM can use on the next connect to the XCF LOCK structure. Use this command only for data sharing.

MODIFY irlmproc,SET,TIMEOUT=nnnn,subsystem-name

Sets the timeout value for the specified Db2 subsystem. Display the subsystem-name by using MODIFY irlmproc,STATUS.

MODIFY irlmproc,SET,TRACE=nnn

Sets the maximum number of trace buffers that are used for this IRLM.

MODIFY irlmproc,STATUS,irlmnm

Displays the status of a specific IRLM.

MODIFY irlmproc,STATUS,ALLD

Displays the status of all subsystems known to this IRLM in the data sharing group.

MODIFY irlmproc,STATUS,ALLI

Displays the status of all IRLMs known to this IRLM in the data sharing group.

MODIFY irlmproc,STATUS,MAINT

Displays the maintenance levels of IRLM load module CSECTs for the specified IRLM instance.

MODIFY irlmproc,STATUS,STOR

Displays the current and high-water allocation for private virtual (PVT) storage, as well as storage that is above the 2-GB bar.

MODIFY irlmproc,STATUS,TRACE

Displays information about trace types of IRLM subcomponents.

Each IMS and Db2 subsystem must use a separate instance of IRLM.
