This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
I've developed a "batch process" which uses three different databases(two sql servers and one oracle). The application uses two different connection pools ; one for sql server and another one for oracle. The remaining sql server I've to connect using Data Source Name(DSN) defined in the data source. I am using sun's odbc-jdbc bridge mechanism/tool/driver to get connection and I am not using connection pool. Whenever need connection, the application will pass the dsn, user and password, and a new connection will be created. the application creates and uses 3 connections per minute in an average.
I am getting this error after sometimes 609th, 1222th, or 1069th connections for the same database. As soon the application gets this error, the JVM is killed.
PLEASE HELP ME and if you need more info. pl. let me know
