A system administrator is monitoring the Activity Logs in WebSphere Message Broker Explorer and
notices the following error:

Which component caused the error?

A system administrator tries to start a second broker in a AIX LPAR, but the broker can not be
started. The system administrator reviews the local error log (syslog) and finds the error BIP2228E.
The abend file mentions Function:semctl(). What should the system administrator do to start the
second server?

A team of developers are testing their message flows for their performance. During testing, the team
finds that one of their DataFlowEngine processes associated with an execution group EG3 containing
10 different message flows is growing continuously in its memory usage. The team reports the
incident to their system administrator. What is the right thing for the system administrator to do?

A system administrator was notified that all the message flows deployed to one of the execution
groups EG1 running on their production broker BRK1 are getting slower and slower to process
messages over a period of time. The system administrator wants to ensure that no user traces are
enabled on this execution group. Which command should the system administrator run to check
this?

There are two developers (D1 and D2) who belong to security group G1. The developers are sharing
broker BRK1 with two execution groups (EG1 and EG2) in the development environment. Each
developer can deploy a BAR file in both execution groups. A system administrator is asked to enable
the administration security on the broker so that each developer can access only one execution
group and no new execution group can be created by either developer.
Which commands does the system administrator have to run?
