warning: greenhorn = me.
I am getting the following error message in my log file whenever I run my
Java app which makes connections to an Oracle DB:
SQLException: Io exception: Connection refused
(DESCRIPTION=(ERR=1153)(VSNNUM=169869568)(ERROR_STACK=(ERROR=(CODE=1153)(EMFI=4)
(ARGS='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.###.###)(PORT=1521)))
(CONNECT_DATA=(CID=(PROGRAM=)(HOST=__jdbc__)(USER=))null))'))(ERROR=(CODE=303)(EMFI=1))))
I am sure the HOST is correct. I have also tried using the server name.
Using google fu, I've found references to needing to use a driver called classes12.jar Although I'm not quite sure what to do with it (I've place it in different locations of the app directory but it didn't do anything)
Let me know what other information I can share to help me solve my problem.
Background info, we've recently changed from using a single node to load balancing 2 nodes. That is when the problem started (and when I inherited this application).
I should also warn that this is my first programming/DB assignment coming from a hardware backround. I miss the warm comforts of my switches and routers....
Thank you in advance.
