Hello,
Below is my setup for executing a background thread with its own
EOObjectStoreCoordinator and its own EOEdtingContext. Note that I'm
using ERXEC to create the EOEditingContext, and have the below
properties set. Also note that I don't do lock or unlock as I
understand that ERXEC does this for you. Is this correct? Is it ok
to use this in a thread? The reason I ask is that I can kick off the
thread and not touch my app in any other way, and more often than not
the calculations will hang after about 15 minutes as if its
deadlocked. However I haven't been able to repeat the error with lock
logging on yet. Could it have something to do with the Session timing
out during processing? Or is there something else I don't have quite
right?
er.extensions.ERXApplication.useEditingContextUnlocker=true
er.extensions.ERXEC.defaultAutomaticLockUnlock=true
er.extensions.ERXEC.useSharedEditingContext=false
er.extensions.ERXEC.defaultCoalesceAutoLocks=true
er.extensions.ERXEnterpriseObject.applyRestrictingQualifierOnInsert=true
er.extensions.ERXEnterpriseObject.updateInverseRelationships=true
public static void updateResults() {
//Do lots of loops
while (...) {
resultsObjectStore = new EOObjectStoreCoordinator();
resultsEC = ERXEC.newEditingContext(resultsObjectStore);
//Do lots of processing.
resultsEC.saveChanges();
//Free up the memory, nothing will be reused in next loop anyway.
resultsEC.dispose();
resultsObjectStore.dispose();
resultsObjectStore = new EOObjectStoreCoordinator();
resultsEC = ERXEC.newEditingContext(resultsObjectStore);
}
}
public static void updateResultsThread() {
t = new Thread("updateResults") {
public void run() {
updateResults();
}
};
t.start();
}
Thanks!
Jeff
