We recently upgraded BIRT from 2.3.2 to 4.4.2 using the WebViewerExample from birt-runtime-osgi-4_4_2. Though we can upgrade to higher versions of BIRT, it is not an option to upgrade to any lower versions than 4.4.2.
We have as our setup:
JBoss 3.x
Java 8
Postgres as our database
Most of our reports work fine with the upgrade. Two reports had issues with Bidi.java, but were fixed when we downgraded the com.ibm.icu* jar in WEB-INF/lib and WEB-INF/platform/plugin to a lower version.
But one report is having issues and I am running out of hair to tear out. Before the upgrade, we had the connection pool set to 15. After the upgrade, it was throwing a JDBCException, but when we increased the connection pool to 16, the report ran fine. However, if two people run the same report at the same time, it throws an error. We have not changed anything on the JBoss side and because we have a lot of customers who run reports at the same time, increasing the connection pool is not a sustainable solution. My question is, how did BIRT 4.4.2 change from 2.3.2 in its utilization of the connection pool? And how can I change it back to how 2.3.2 was using it?
Some things we have already tried (please see log below):
-Increasing the timeout to 60,000 ms
-Putting our postgres driver jar (postgresql-9.3-1104.jdbc41.jar) inside WEB-INF/lib or WEB-INF/platform/plugins/org.eclipse.birt.report.data.oda.jdbc_4.4.2.v201410272105/drivers or both
-There is nothing wrong with the hostname/port number for JNDI connection as other reports use the same and is connecting with no issues
Here are some lines from the BIRT logs that may be helpful (set to FINEST):
