I don't consider this a bug. Doing a commitChanges() does not discard all objects from the DataContext after the commit -- after all, you might need them again. There are methods to discard (invalidate) objects from the DataContext if you wish, or you can create a new DataContext and allow the previous one to be garbage collected.
/dev/mrg -----Original Message----- From: Paul Ponec (JIRA) [mailto:[EMAIL PROTECTED] Sent: Thursday, August 03, 2006 6:05 AM To: [email protected] Subject: [JIRA] Created: (CAY-620) DataObject memory management DataObject memory management ---------------------------- Key: CAY-620 URL: http://issues.apache.org/cayenne/browse/CAY-620 Project: Cayenne Type: Bug Components: Cayenne Core Library Versions: 2.0 [STABLE] Environment: Oracle Application server was launched with -Xmx30m. Oracle DB version: Oracle Database 10g Enterprise Edition Release 10.1.0.4.2 - Production With the Partitioning, OLAP and Data Mining options OS: Windows XP or Linux Fedora Reporter: Paul Ponec Priority: Minor Hi, I am reusing my instance of DataObject after calling context.commitChanges(). In the case my application throws OutOfMemoryError exception after 30000 inserts approximately on Oracle DB but I am expecting all resources will be released after the commit. The commit is preformed for each new data object in my plain code: public void run() { int MAX_LIMIT = 200*1000 ; DataContext context = DataContext.createDataContext(); for (int i=0; i<=MAX_LIMIT; i++) { User user = (User) context.createAndRegisterNewObject(User.class); user.setAttrib1("1"); user.setAttrib2("2"); user.setAttrib3("3"); context.commitChanges(); } } Note: - No stack trace is available - It seems, a Derby DB works correctly on the same code. I have found a solution for the bug: Create new data context after commit by sample: context = DataContext.createDataContext(); Regards Paul -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/cayenne/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
