J2EE troubleshooting tips : how to start searching through the log files

When the jcontrol fails before it reaches ‘starting processes’ check first the bootstrap logs.

Bootstrap logs are located in \usr\sap\<SID>\<instance>\work

In these logs you find log-information on the beginning of the startup process of the J2EE engine.

Most important ones are:

dev_bootstrap

dev_dispatcher

dev_server

When the jcontrol fails shortly after start with ‘some processes running’ check first the dispatcher logs.

Dispatcher logs are located in \usr\sap\<SID>\<instance>\ j2ee\cluster\dispatcher\log

Specially check the latest defaulTrace.<x>.trc

When the jcontrol fails some after start with ‘some processes running’ check first the server logs.

Server logs are located in \usr\sap\<SID>\<instance>\ j2ee\cluster\server0\log

Specially check the latest defaulTrace.<x>.trc

  • Hi Premsukh,

    Even though the idea for the blog is good the content is very limited, Also a blog should reflect your particular opinion about a subject otherwise is just a technical document.

    I think you should expand on the subject and add your experiences troubleshooting Java instances.

    Regards, JP
