Usage notes for RESET QMGR
You can use this command to request that the queue manager starts writing to a new log extent, making the previous log extent available for backup. See Updating a backup queue manager. Alternatively, you can use this command to request that the queue manager ends the current statistics collection period and writes the collected statistics. You can also use this command to forcibly remove a publish/subscribe hierarchical connection for which this queue manager is nominated as either the parent or the child in the hierarchical connection.
- The queue manager might refuse a request to advance the recovery log, if advancing the recovery log would cause the queue manager to become short of space in the active log.
- You are unlikely to use RESET QMGR TYPE(PUBSUB) other than in
exceptional circumstances. Typically the child queue manager uses
ALTER QMGR PARENT(' ') to remove the hierarchical connection.
When you need to disconnect from a child or parent queue manager with which the queue manager has become unable to communicate, you must issue the RESET QMGR TYPE (PUBSUB) command from a queue manager. When using this command, the remote queue manager is not informed of the canceled connection. It might, therefore, be necessary to issue the ALTER QMGR PARENT(' ') command at the remote queue manager. If the child queue manager is not manually disconnected, it is forcibly disconnected and the parent status is set to REFUSED.
If you are resetting the parent relationship, issue the ALTER QMGR PARENT(' ') command, otherwise the queue manager attempts to re-establish the connection when the publish/subscribe capability of the queue manager is later enabled.
Parameter descriptions for RESET QMGR
- TYPE
-
- ADVANCELOG
- Requests that the queue manager starts writing to a new log extent, making the previous log extent available for backup. See Updating a backup queue manager. This command is accepted only if the queue manager is configured to use linear logging.
- STATISTICS
- Requests that the queue manager ends the current statistics collection period and writes the collected statistics.
- PUBSUB
- Requests that the queue manager cancels the indicated publish/subscribe
hierarchical connection. This value requires that one of the CHILD
or PARENT attributes is specified:
- CHILD
- The name of the child queue manager for which the hierarchical connection is to be forcibly canceled. This attribute is used only with TYPE(PUBSUB). It cannot be used together with PARENT.
- PARENT
- The name of a parent queue manager for which the hierarchical connection is to be forcibly canceled. This attribute is used only with TYPE(PUBSUB). It cannot be used together with CHILD.
- CMDSCOPE
- This parameter applies to z/OS only and specifies how the command is executed when the queue manager
is a member of a queue-sharing group. CMDSCOPE must be blank, or the local queue manager, if QSGDISP is set to GROUP.
- ' '
- The command is executed on the queue manager on which it was entered. This value is the default value.
- qmgr-name
- The command is executed on the queue manager you specify, providing
the queue manager is active within the queue-sharing group.
You can specify a queue manager name other than the queue manager on which it was entered, only if you are using a shared queue environment and if the command server is enabled.
- *
- The command is executed on the local queue manager and is also passed to every active queue manager in the queue-sharing group. The effect of setting this value is the same as entering the command on every queue manager in the queue-sharing group.
