APAR status
Closed as program error.
Error description
If an Integration Server is deployed with an MQ node flow having similar MQ Client connection settings as an SSL configured MQ node but 'use SSL' property unchecked, then the SSL configured MQ node may also attempt a non SSL MQ connection. This can cause MQ Connection failure with MQRC 2393 and broker syslog file getting logged with a BIP2677E error message. BIP2677E: ( BKR10.default ) Failed to make a client connection to queue manager ''QMGR_SSL'' using hostname ''localhost'' on port '1224': MQCC=2; MQRC=2393.
