CSQX036E CSQXSUPR Unable to open SYSTEM.BROKER.ADMIN.STREAM
When implementing pubsub an attempt to open the above stream fails with security error MQCC=2 MQRC=2035
Accepted answer
The queue manager has not been authorized to this object. The failing security check is for UPDATE authority against the system topic xxxx.PUBLISH.SYSTEM.BROKER.ADMIN.STREAM in class MXTOPIC
Add the appropriate TOPIC security (depending on the security product used). A cycle of the MQ subsystems would put these changes into effect.
Note that the InfoCenter documents the necessary accesses required for the CHIN subsystem when using pubsub.
