| What r the steps to get an existing V7 broker to point to SAN for HA CMP. I know I do an mqsiaddinstance on the second but all instructions say to create the first broker. Mine is already there. |

you need to move the relevant work directory on to san.
I would expect that to be all under /var/mqsi
see /var/mqsi/components/<brokername>...
Have fun

You stop the broker, move to san and mount the san at the same point so that the path has not changed...

| Or just move the relevant parts of the file system (registry and components) and symlink them (like the HA support pac for WMB does). |

Hi,
I think you should study support pack "IC91: High Availability for WebSphere Message Broker on Distributed Platforms" to find out what is required for HA configuration before you do your changes to existing environment.

The IC91 Support Pack is really only applicable to brokers with a version less than 7.0.0.0.
If you have scripts to create, provision and deploy objects to your existing broker it should be fairly simple to drop the broker and re-create it as a multi-instance one.
This is always assuming that you have configured the underlying Queue Manager into the HA environment.

I use IC91 with broker 7 (as I don't want a mixture of types of HA setup and also I may upgrade brokers in place).
Works fine (leaving out the config manager and DB2 of course).
This script below can be used to move & symlink your non-SAN directories to SAN. Use at own risk of course.
| Code: |
#!/bin/ksh
#
# This script fixes an MQSI broker so that it can once again run in an HA
# cluster, following a mqsirestorebroker (which resets the HA symbolic links)
# set the name of the broker and MQ HA data mount point in this script
if [ `id -u` -ne 0 ]
then
echo "Must be running as root"
exit 1
fi
BROKER=<brokername>
DATAPATH=/MQHA/<brokername>/data
curdir=`pwd`
cd /var/mqsi/components
echo "Moving components/$BROKER directory back to $DATAPATH"
if [ ! -d $DATAPATH/components ]
then
mkdir $DATAPATH/components
fi
cp -Rp $BROKER $DATAPATH/components
rm -fr $BROKER
ln -fs $DATAPATH/components/$BROKER $BROKER
cd /var/mqsi/registry
echo "Moving registry/$BROKER directory back to $DATAPATH"
if [ ! -d $DATAPATH/registry ]
then
mkdir $DATAPATH/registry
fi
cp -Rp $BROKER $DATAPATH/registry
rm -fr $BROKER
ln -fs $DATAPATH/registry/$BROKER $BROKER
cd $curdir
echo "ended - check the outcome"
exit 0

| The confirmation that IC91 is still an option was a valuable post. Thanks you also for the script. I have also put up a WMB Requirement to add any and all of this to the Infocenter including the lab thinking about adding a simular -e parm to the mqsichangebroker. There is one now but it is nothing like the -e on the other commands. Thanks everyone who posted, back on course. |
