SUMA |
Description. Dumps information about subscription resources.
Sample Output.
Node 2: Suma: c_subscriberPool size: 260 free: 258 Node 2: Suma: c_tablePool size: 130 free: 128 Node 2: Suma: c_subscriptionPool size: 130 free: 128 Node 2: Suma: c_syncPool size: 2 free: 2 Node 2: Suma: c_dataBufferPool size: 1009 free: 1005 Node 2: Suma: c_metaSubscribers count: 0 Node 2: Suma: c_removeDataSubscribers count: 0
Additional Information.
When subscriberPool ... free becomes and
stays very low relative to subscriberPool ...
size, it is often a good idea to increase the
value of the
MaxNoOfTables
configuration parameter
(subscriberPool = 2 *
MaxNoOfTables). However, there could also
be a problem with API nodes not releasing resources
correctly when they are shut down. DUMP
8004 provides a way to monitor these values.
