[Design of JBoss Profiler] - Re: OutOfMemory Exception Generating reports

by jesper.pedersen

This is the only forum currently, so feel free to post here. Sounds like an interesting use-case :) Yes, you use the 'load' command with the top-level directory (the one with the timestamp name) as input. What is the size of the directory you are trying to load ? It sounds there is a lot of data. I would like a copy of the data (if possible), since I havn't worked with very big profiles yet (only up to ~200MB). Therefore there are probably stuff that can be optimized in the client in order to reduce memory requirements during report generation. TIA !

Ok I understand now. The obvious first question is why is it merging scopes? You did this change. Merging the scopes is broken since any deployer that wants to "play with" the metadata will be using the wrong scope, i.e. the wrong metadata. Especially the mutable scope!

[Design of JBoss Profiler] - OutOfMemory Exception Generating reports

by andy.miller＠jboss.com

There wasn't a separate user forum, so I'm posting here. If I'm mistaken, just point me at the right place, and I'll post there. After using the file store to do a longer running capture, I'm trying to use the client, but I keep getting an OutOfMemory exception. There are 160 directories in the capture, and I have used as large as a 3828MB heap, but to no avail. Is there something I'm doing wrong? I assume that with the client you use the load command, and give the top level directory. Is that wrong? Should I run against all the individual directories one at a time? Thanks for any help.

[Design of the JBoss EJB Container] - Re: NPE in JDBCStoreManager

by alex.loubyansky＠jboss.com

"scott.stark(a)jboss.org" wrote : It looks like the EjbModule is starting the pm before the entity container has been started. Why don't we start the pm from the EntityContainer.startService? It's dictated by the current logic behind the (CMP) persistence manager start: - first every persistence manager in the EJB module performs its initStoreManager(); - then after all of them initialized, they can be started which includes resolution of CMR and foreign keys (which is the reason why they are started in this way). So, calling start on one of the PMs won't actually start the PM. Only when the last PM in the EJB module receives the start call they get started. So, if the PM.start() were in EntityContainer.startService() then after return from EntityContainer.startService(), the container's PM might not had been started and the container would not be usable.
