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.

The Eric S. Emrick Blog. Thursday, April 27, 2006. The Oracle Certification Process. Years of Oracle work to date - I had reached an Oracle summit. At that time the OCP title was not nearly as pervasive as it is today. In hindsight, I suppose my enthusiasm was not entirely unjustified. Let’s roll time forward nine years to 2006. I have not. Professionally, on my resume, I suppose the answer is yes. Realistically, the answer is, no way! 1 Want to learn. 2 Be passionate about the topic. Absolutely. But...

The Eric S. Emrick Blog. Thursday, August 31, 2006. Ever see something so inefficient it evokes images of grape stomping to produce wine? I have, in Oracle 10g no less. A colleague of mine brought me a situation the other day that made me do a double-take, no triple-take, on a 10046 trace.
