This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
In our aplication we are recieving the following closed connection exception randomly.
java.sql.SQLException: Closed Connection
And this exception is thrown from different class. But when the same screen is accessed again then these exceptions arent thrown. This happens wehn the application uis loaded with more users.
We are using weblogic 7.0 and database Oracle 9i. JDK1.4 and JDBC version 220.127.116.11.0
Is this because of a connection breakage between the appl server and db server? Though when thse above error occurs, i could connect to database from sql plus.
I see an option in weblogic to test Reserved/Released connection; if we enable this option, will it have any adverse effect in the application performance > I believe this will validate the connection everytime the client request for a new conenction from the weblogic pool.
Please throw some light.
