Air Cleaner User Manual

You can specify a queue manager name, other than the queue
manager on which the command was entered, only if you are
using a queue-sharing group environment and if the command
server is enabled.
MODE(QUIESCE)
Stops any new update activity on the MQSeries subsystem for a specified
period of time, and brings all existing users to a point of consistency after
a commit. When the specified period of time expires, archiving of the
current active log takes place.
The period of time specified is the maximum time that MQSeries has to
attempt a full subsystem quiesce.
If MODE(QUIESCE) is issued without the TIME parameter, the value in
the QUIESCE parameter of the CSQ6ARVP macro is used as the quiesce
time period.
TIME(nnn)
Overrides the quiesce time period specified by the QUIESCE parameter of
the CSQ6ARVP macro.
nnn is the time, in seconds, in the range 001 through 999.
To specify the TIME parameter, you must also specify MODE(QUIESCE).
If you specify the TIME parameter, you must specify an appropriate period
of time for the quiesce period. If you make the period too short or too
long, one of the following problems might occur:
v The quiesce might not be complete
v MQSeries lock contention might develop
v A timeout might interrupt the quiesce
WAIT
Specifies whether MQSeries is to wait until the quiesce process has
finished before returning to the issuer of the ARCHIVE LOG command, or
not.
To specify the WAIT parameter, you must also specify MODE(QUIESCE).
NO Specifies that control is returned to the issuer when the quiesce
process starts. This makes the quiesce process asynchronous to the
issuer; you can issue further MQSeries commands when the
ARCHIVE LOG command returns control to you. This is the
default.
YES Specifies that control is returned to the issuer when the quiesce
process finishes. This makes the quiesce process synchronous to the
issuer; further MQSeries commands are not processed until the
ARCHIVE LOG command finishes.
Usage notes
1. You cannot issue an ARCHIVE LOG command while a previous ARCHIVE
LOG command is in progress.
2. You cannot issue an ARCHIVE LOG command when the active log data set is
the last available active log data set, because it would use all the available
active log data set space, and MQSeries would halt all processing until an
off-load had been completed.
