Watching MQ Traffic with OpenSSO Express

If you are using the new OpenSSO Express build 4.5 and want to watch as session updates, additions, or deletions are recorded to the amsessiondb.log when session failover is enabled, you must set the AMSESSIONDB_ARGS attribute with a value of "-v" in the amsfo.conf file. Then you can grep for MQ traffic with the following:

tail -f amsessiondb.log > a
grep WRITE a | wc; grep DELETE a | wc; wc a

Here is an example of what the log file that records writes looks like:

Starting...  true
   /usr/jdk/instances/jdk1.5.0/jre/bin/java -Xms128m -Xmx512m -classpath /opt/opensso/instance1/sfo/jmq/mq/lib/imq.jar:/opt/opensso/instance1/sfo/jmq/mq/lib/jms.jar:/opt/opensso/instance1/sfo/ext/je.jar:/opt/opensso/instance1/sfo/locale:/opt/opensso/instance1/sfo/lib/am_sessiondb.jar:. com.sun.identity.ha.jmqdb.client.FAMHaDB
