2025 (07E9) (RC2025): MQRC_MAX_CONNS_LIMIT_REACHED
Explanation
The MQCONN or MQCONNX call was rejected because the maximum number of concurrent connections has been exceeded.
- On z/OS®, the connection limits are 32767 for both TSO and Batch.
- On Multiplatforms, this reason code can also occur on the MQOPEN call.
- When using Java applications, the connection
manager might define a limit to the number of concurrent connections. Note: The application using IBM® MQ might have delegated the management of connections to a framework or connection pool, for example, a Java EE application server, an application framework such as Spring, an IBM Container (for IBM Cloud® (formerly Bluemix®)), or a combination of these. For more information, see IBM MQ classes for JMS object pooling.
Completion code
MQCC_FAILED
Programmer response
Either increase the size of the appropriate parameter value, or reduce the number of concurrent connections.
