ChinitAdapters (MQLONG)

This is the number of adapter subtasks to use to process IBM MQ calls. The value must be 0 - 9999, with a default value of 8.

The ratio of adapters to dispatchers (the ChinitDispatchers attribute) should be about 8 to 5. However, if you have only few channels, we do not have to decrease the value of this parameter from the default value. We can use the following values: for a test system, 8 (default); for a production system, 20. Ideally, we should have 20 adapters, which gives greater parallelism of IBM MQ calls. This is important for persistent messages. Fewer adapters might be better for nonpersistent messages.

This attribute is supported on z/OS only.

To determine the value of this attribute, use the MQIA_CHINIT_ADAPTERS selector with the MQINQ call.
