Advanced tuning for Native HA CRR
Advanced settings for tuning timings and intervals. There should be no need to use these settings unless the defaults are known not to match your system's requirements.
The basic options for configuring Native HA CRR are handled using the
QueueManager API, which the IBM® MQ Operator
uses to configure the underlying queue manager INI files for you. There are some more advanced
options that are only configurable using an INI file, under the NativeHARecoveryGroup stanza of
the qm.ini file . See also Example: Supplying MQSC and INI files for more information on
how to configure an INI file.
ShortRetryTimer- Specifies the interval to wait between attempts to connect to a Recovery group in the short retry phase. Specified in milliseconds, defaults to 2500 (2.5 seconds).
ShortRetryCount- Specifies the number of attempts to make a connection to the Recovery group during the short retry phase.
LongRetryTimer- Specifies the interval to wait between attempts to connect to a Recovery group in the long retry
phase. The long retry phase continues indefinitely until connection is made, or until the
configuration is changed to comment out or remove the
ReplicationAddress. Specified in milliseconds, defaults to 60000 (60 seconds). RetryReporting- Set to
PhaseorAllto specify whether each retry attempt is reported, or just the phase (long or short). If not specified, defaults toPhase. StatusInterval- Specifies the longest time interval that the Recovery group will wait before sending a Recovery log status. Specified in milliseconds, defaults to 10000 (10 seconds).
StatusCommitThreshold- Specifies the maximum number of bytes that the Recovery group commits before sending a Recovery
log status. Specified in bytes and defaults to 0, which means that
StatusIntervalalone is used to determine when Recovery log status is sent.
