Hi

Fist of all check the work Directory for error Logs.

Arrange the work directory by last changed date.
Then you will get the latest logs for Error.

dev_disp related to dispatcher
dev_server0 is related to server0 for java.

also check dev_jcontrol and dev_jcom,

For detailed trouble shooting of Java Systems,
You can go to the
Directoty, /usr/sao/<SID>/j2ee/cluster/server0/logs

There you can check the default Trace logs..

For Further more logs,
goto System Folder inside of Logs..

Any security related issues is there, u can get the exact
reason from there itself.

main source where failure occurs.check whether DISP+WP is
active if it is active then SAP system is up and if DISP+WP
is inactive then it means the SAP system is down.
