JMQI stanza of the client configuration file

Use the JMQI stanza to specify configuration parameters for the Java Message Queuing Interface (JMQI) used by the IBM® MQ classes for Java and IBM MQ classes for JMS.

Note: The description of each attribute of this stanza indicates which IBM MQ clients can read that attribute. For a summary table for all IBM MQ MQI client configuration file stanzas, see Which IBM MQ attributes can be read by each client.

The following attribute can be included in the JMQI stanza:

useMQCSPauthentication = NO|YES

Controls whether IBM MQ classes for Java and IBM MQ classes for JMS applications should use Compatibility mode or MQCSP authentication mode when authenticating with a queue manager.

This attribute can be read by IBM MQ classes for Java, and IBM MQ classes for JMS clients.

This attribute can have the following values:

NO: Use compatibility mode when authenticating with a queue manager. This is the default value in versions earlier than IBM MQ 9.2.1.
YES: Use MQCSP authentication mode when authenticating with a queue manager. This is the default value from IBM MQ 9.2.1.

There are several other ways to set the authentication mode that take precedence over the value of the useMQCSPauthentication attribute. For more information about Compatibility mode and MQCSP authentication mode, see Connection authentication with the Java client.
