oacore / forms stdout eating up your CPU and I/O? It’s a bug!!

We’re going live ina few weeks and and my performance tests showed me a distrubing trend. The oacore processes would consume about 40% CPU between them and were churning out 8 GB’s of stdout files for each managed servers in a few hours.

Opening an SR gave me a method to create a filter that would filterout these message but I had to use the EBS scritps to start and stop these managed servers then. And I liked the WL control console 🙂

After a bit of further digging, I chanced upon Oracle Doc ID 1981206.1, which points to bug 18345006.

JBO DEBUG LOGGING ON WITHOUT -D FLAG, NOTICE LEVEL AND PROD MODE=TRUE

After applying the patch jbo messages are no longer being thrown into teh std out, and the CPU and I/O are very normal now
