AMQ9777: Channel was blocked



The inbound channel 'CHANNEL.SVRCONN' was blocked from address ''

because the active values of the channel matched a record configured with

USERSRC(NOACCESS). The active values of the channel were 'CLNTUSER('.


Contact the systems administrator, who should examine the channel

authentication records to ensure that the correct settings have been

configured. The ALTER QMGR CHLAUTH switch is used to control whether channel

authentication records are used. The command DISPLAY CHLAUTH can be used to

query the channel authentication records.

what mq client version do you use?
