Okay, I've figured out how to set this up across servers, but I'm still seeing the exception. Doesn't seem to cause any problems but I haven't met a stack trace I like.
I'm a little unsure exactly why you need to make the choice between using the remote synchronizer and using setFetchTimestamp(System.getCurrentTimeInMillis()) on EC creation. Isn't the end effect really the same? The DB cache gets the freshest data in both cases, no? Thanks. -Mike From: [email protected] [mailto:[email protected]] On Behalf Of Michael Gargano Sent: Monday, December 12, 2011 4:50 PM To: WebObjects webobjects-dev Subject: ERXObjectStoreCoordinatorPool exception Hi again, I just configured the ERXObjectStoreCoordinatorPool have 4 coordinators using the ERJGroupSyncronizer. I have 2 application servers running 2 apps each. The apps on each box talk to each other and both servers share one DB. Server A Server B --------------------------- --------------------------- myApp myApp taskRunnerApp taskRunnerApp \ / DB Server Everything seems to be running okay, but now that I've turned on the coordinator pool I see this strange exception. ERROR er.extensions.eof.ERXObjectStoreCoordinatorSynchronizer - java.lang.NullPointerException NullPointerException at er.extensions.eof.ERXEOAccessUtilities.databaseContextForEntityNamed(ERXEOAccessUtilities.java:1011) at er.extensions.eof.ERXObjectStoreCoordinatorSynchronizer$ProcessChangesQueue._process(ERXObjectStoreCoordinatorSynchronizer.java:490) at er.extensions.eof.ERXObjectStoreCoordinatorSynchronizer$ProcessChangesQueue.process(ERXObjectStoreCoordinatorSynchronizer.java:521) at er.extensions.eof.ERXObjectStoreCoordinatorSynchronizer$ProcessChangesQueue.run(ERXObjectStoreCoordinatorSynchronizer.java:598) ... skipped 1 stack elements Anything to be concerned about? I also set both apps to use the same group name, so I assume that means that it's syncing the EOF stacks across both apps. Is there a way to do this across servers as well, and is that even a good idea? Thanks. -Mike
