User IDs used by the channel initiator
This collection of topics describes the user IDs used and checked for receiving channels and for client MQI requests issued over server-connection channels. Information is provided for TCP/IP and for LU6.2
You can use the PUTAUT parameter of the receiving channel definition to determine the type of security checking used. To get consistent security checking throughout your IBM® MQ network, you can use the ONLYMCA and ALTMCA options.
You can use the DISPLAY CHSTATUS command to determine the user identifier used by the MCA.
