Restrictions and variations for MQCNO_* values in IBM MQ classes for Java
Certain MQCNO_* values are not supported.
- Automatic client reconnect is not supported by the IBM MQ classes for Java™. Whatever value MQCNO_RECONNECT_* you set, the connection continues to behave as if you set MQCNO_RECONNECT_DISABLED.
- MQCNO_FASTPATH is ignored on queue managers that do not support MQCNO_FASTPATH. It is also ignored by client connections.
