Sun Cluster Data Service for WebSphere MQ Guide for Solaris OS

Configuration Requirements

The requirements in this section apply to Sun Cluster HA for WebSphere MQ only. You must meet these requirements before you proceed with your Sun Cluster HA for WebSphere MQ installation and configuration.

Caution – Caution –

Your data service configuration might not be supported if you do not adhere to these requirements.

Example 3 Manual attempt to start the WebSphere MQ Manager by mistake.

# strmqm qmgr1
# Request to run </usr/bin/strmqm qmgr1> within SC3.0 has been refused

This solution is required only if you require a Global File System for the WebSphere MQ instance. Example 4 details the steps that you must take to achieve this.

Example 4 Create a symbolic link for strmqm and endmqm to check-start

# cd /opt/mqm/bin
# mv strmqm strmqm_sc3
# mv endmqm endmqm_sc3
# ln -s /opt/SUNWscmqs/mgr/bin/check-start strmqm
# ln -s /opt/SUNWscmqs/mgr/bin/check-start endmqm

Edit the /opt/SUNWscmqs/mgr/etc/config file and change the following entries for START_COMMAND and STOP_COMMAND. In this example we have chosen to add a suffix to the command names with _sc3. You can choose another name.

# cat /opt/SUNWscmqs/mgr/etc/config
