COUNTERS SYNCHRONIZE

Synchronize each of the node-specific, in-memory caches of channel counters with the cluster-wide database.

Syntax

COUNTERS SYNCHRONIZE

Command Qualifiers Defaults
/TIMEOUT=seconds /TIMEOUT=120

Parameters

None.

Description

To synchronize each of the node-specific, in-memory cache of channel counters with the cluster-wide database, issue a COUNTERS SYNCHRONIZE command. The command will not return control back to you until either all the caches have been synchronized or a "timeout" period has elapsed. Should the timeout period elapse, then control will be returned to you. However, the synchronization process will continue in the background. Use the /TIMEOUT qualifier to adjust the timeout period which has a default value of 120 seconds.

Note that SYSLCK privilege is required to use this command.

Note that the COUNTERS SYNCHRONIZE command signals each PMDF counters synchronization process in the cluster to perform the synchronization---there should be one such process on each node running PMDF. Note that on each node, the synchronization can only be performed if the PMDF counters synchronization process is running on that node.

Assuming that the PMDF counters synchronization process is running on each node, then for each node the node-specific, in-memory cache will be created, if it does not already exist. If the cluster-wide, on-disk database does not exist, it will be created. The in-memory cache values will be used to update the on-disk database, and then the on-disk database values for stored messages, recipients, and volume will be set by scanning the PMDF queue cache database.


Command Qualifiers

/TIMEOUT=seconds

By default, QM will wait upwards of 120 seconds for the node-specific caches to be synchronized. Should the synchronizations not be completed before the specified time period, QM will return control to you prompting you for another command. The synchronization process will, however, continue in the background.
