Fix Recommendation

The ISSO will ensure that all WebSphere MQ started tasks are properly defined.

Review WebSphere MQ started tasks and ensure the following items are in effect:

Note: ssid is the queue manager name (a.k.a., subsystem identifier).
ssidMSTR is the name of a queue manager STC.
ssidCHIN is the name of a distributed queuing (a.k.a., channel initiator) STC.

Each WebSphere MQ started task is associated with a unique logonid.

Each WebSphere MQ STC logonid has the attributes of STC, MUSASS, and NOSMC.

Example:

SET LID
INSERT ssid.MSTR NAME(MQseries, STC) STC MUSASS NO-SMC

INSERT ssid.CHIN NAME(MQseries, STC) STC MUSASS NO-SMC

Check Contents

Refer to the following reports produced by the ACF2 Data Collection:

- ACF2CMDS.RPT(LOGONIDS).
- ACF2CMDS.RPT(ATTSTC).

Note: ssid is the queue manager name (a.k.a., subsystem identifier).

Provide a list of all WebSphere MQ Subsystem IDs (Queue managers) and Release levels.

ssidMSTR is the name of a queue manager STC.
ssidCHIN is the name of a distributed queuing (a.k.a., channel initiator) STC.

Review WebSphere MQ started tasks and verify the following items are in effect. If they are, this is not a finding.

Each ssidMSTR and ssidCHIN started task is associated with a unique logonid.
Each ssidMSTR and ssidCHIN STC logonid has the following attributes defined.

STC
MUSASS
NOSMC

Repeat these steps for each queue manager ssid.
