DB2 and Minerva Pool
I am having a problem with DB2 Version 7. I've run this same application against Informix and Oracle and it works just fine. Here is the problem:
This is an EJB application. The session bean runs a method that processes 200 inserts into a table in DB2. The method retrieves a pool connection and attempts to make the 200 inserts. The results are unpredictable in that I may get 50 inserts done or 150 done before I get the error shown at the bottom of this message. The error seems to be happening everytime the program hits a conPool.commit() statement and I'm using a connection from Minerva.
If I switch to a straight connection, bypassing the pool, everything works as expected. That is, no errors in the commit statement.
Any ideas????
