I suggest you call Alfresco Support.
They will almost certainly ask for more information like stack dumps and performance monitoring results.
Why did you think you needed to reindex lucene? And did it make a difference?

From what you posted db.pool.max=275 may be worth increasing this a bit. Depends upon your load.
And is your oracle database running O.K. have you gathered the stats recently?

Hi MrRogers,

The database is running OK, Oracle ADDM is not showing any warnings or errors.
Also we tried to rebuild the Alfresco indexes in the database, this didn't make any difference.

We editted some more config settings which show Alfgresco is faster:

export CATALINA_OPTS="-Xms8G -Xmx8G -XX:MaxPermSize=512M -XXermSize=512M -server -XX:NewRatio=2 -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing -XX:+CMSParallelRemarkEnabled -XX:+UseParNewGC -Xss1m -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=5123 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/opt/alfresco/tomcat/logs -Djava.awt.headless=true -XX:+CMSClassUnloadingEnabled -XX:+CMSParallelRemarkEnabled -XX:CMSInitiatingOccupancyFraction=80 -XX:ReservedCodeCacheSize=256M"

Can you give your humble opinion about these settings?

Thanks in advance,

Regards,

Vincent

I still suggest you contact alfresco support.

So how much faster has the application gone with the removal of Max New Size?

In general I think the current advice is to leave the JVM alone without changing properties. If you have a memory problem then you really need to run a profiler to identify exactly what the problem is.
