ChinitAdapters (MQLONG)

This is the number of adapter subtasks to use to process WebSphere MQ calls. The value must be between 0 and 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 a small number of channels, you do not have to decrease the value of this parameter from the default value. You are recommended to use the following values: for a test system, 8 (default); for a production system, 20. Ideally, you should have 20 adapters, which gives greater parallelism of WebSphere MQ calls. This is particularly 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.
