IBM MQ9 channel creation with name SYSYTEM.DEF.SVRCONN

Question

I am getting the below error while trying to create channel with name SYSTEM.DEF.SVRCONN in IBM MQ9.

DEFINE CHANNEL (system.def.svrconn) CHLTYPE (SVRCONN)
     8 : DEFINE CHANNEL (system.def.svrconn) CHLTYPE (SVRCONN)
AMQ8150E: IBM MQ object already exists.

Any help will be appreciated....

Answer 1

The error means what it says. By default the channel SYSTEM.DEF.SVRCONN exists on all IBM MQ queue managers. The purpose of this specific channel is to provide the default properties to use when new SVRCONN channels are defined.

Despite many examples showing this channel name, it should not be used and is disabled by a default CHLAUTH rule.
