Hello,
I have a problem with a glassfish cluster. The environment is:
Load balancer
Apache 2.2 Proxy (on host A)
Glassfish 3.1.2.2 (on host A)
Apache 2.2 Proxy (on host B)
Glassfish 3.1.2.2 (on host B)
Apex 4.2.2 (on host C)
Oracle 11.2.0.3 (on host C)
Using Oracle's Apex Sample File Upload and Download Code, I fairly often get an Apex "Please select a file to upload." error. The problem seems to be occuring on one node only. In the glassfish access logs, I see a successful POST. I see nothing in the Glassfish server logs. If I use ngrep to look at the Glassfish to database traffic on port 1521 from host B to host C, I see an ORA-01403 "no data found".
If I watch the directory /generated/jsp/apex I can see the file to be uploaded temporarily appear and then go away.
How can I enable more debug logging in Glassfish to track down this issue?
Thanks!
