I am connecting to Oracle 10g RAC using JDBC in Tomcat 6.0.20.
It works around 50% of the time. When it doesnt work it shows this error message:
IO exception: The Network Adapter could not establish the connection.

Here is my JDBC String:
The above Description parameters I use in my tnsnames.ora and can successfully connect to the Oracle RAC using SQL Plus with no issues. I can also successfully ping to the IP addresses with no issues.
I also played around with the JDBC string and added (FAILOVER=ON) but still have same issues.

Please advise.
