Thursday, September 20, 2007. OC4J ping timeout issues. We recently went with a Jdev. Application Server 10.1.3. While the deployment went fine, a few days after the deployment we started noticing oc. 4j ping timeout issues in the opmn. Log After the OC. 4J ping timeout OC. 4J tries to restart itself. We checked the max heap size - the max heap size looks good. There is not much activity on the server so we feel the default ping timeout of 20 seconds should be sufficient. I don't. It can be a JDK.

Monday, November 27, 2006. Recover database until cancel and online redo's. On a noarchivelog mode database, recover database until cancel will still prompt for archive logs.

When prompted if the appropriate online redolog is entered the Incomplete recovery will succeed. Wednesday, November 22, 2006. The PowerC...
