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.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of IBM App Connect Enterprise V11.0 and IBM
    Integration Bus V10.0 using the MQ nodes with SSL.
    
    
    Platforms affected:
    z/OS, MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    If a message flow containing an MQ node with the 'use SSL'
    property unchecked is deployed to an integration server, and
    that non-SSL MQ node has similar MQ client connection properties
    as an SSL configured MQ node deployed in another message flow,
    then the SSL configured MQ node may also attempt a non-SSL MQ
    connection. This can cause an MQ connection failure with
    MQRC=2393 (MQRC_SSL_INITIALIZATION_ERROR) and error BIP2677E
    written to the system log.
    
    BIP2677E: ( BKR10.default ) Failed to make a client connection
    to queue manager ''QMGR_SSL'' using hostname ''localhost'' on
    port '1224': MQCC=2; MQRC=2393.
