Well, if you delegate to your own wrapper of the client you could change the backing client dynamically. When a configuration change is needed you could increment a pool version, configure it as a new pool (e.g. "default_5"), and then atomically change the backing client to a newly instantiated one. This would give you the appearance of changing the pool's configuration. This would also be non-blocking since any current work in the older pool gets to still use that instance until it finishes the code client block and the next request is made from your application uses the updated version.
I haven't tried this, so be warned. :-) -Ben ----- Original Message ---- From: Shlomi Marco <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Cc: [email protected] Sent: Wednesday, January 2, 2008 5:13:01 AM Subject: Re-initing an initialized pool (Java-api) (Problem w/first post...second try) Hey all. I'm trying to change pool setting in "mid-air" (application already init and running for a while, now it needs parameters readjustment, without restarting the VM) >From the look at the code, once pool.initialize() has been called, you cannot >issue another pool.initialize(), Is there a cleaver way to re-init the pool instance (it's a singleton) without modding the client api? (whalin's API) Edit: Just noticed the shutdown()... Edit 2: I'm not sure if it is a bug or by design, but: stopMaintThread() stops, well, the main thread: if ( maintThread != null && maintThread.isRunning() ) maintThread.stopThread(); Now, in startMainThread(), there isn't a case where mainThread isn't null, but is initialized and stopped: if ( maintThread != null ) { if ( maintThread.isRunning() ) { log.error( "main thread already running" ); } else { maintThread.start(); } } else { maintThread = new MaintThread( this ); maintThread.setInterval( this.maintSleep ); maintThread.start(); } } So, calling shutdown() and then calling pool.initialize() again, result in a IllegaleStateException. Am I doing something wrong? is this NOT the way to re-init a pool? or, is it just a bug? ____________________________________________________________________________________ Never miss a thing.
