Check console messages.

Reboot and keep important system log files.

Check hardware components.

Analye with diagnosis tools.

!scalation procedure" call hardware support.

Check main log files.

Analye with diagnostic tools.

#tart up$shut down log files.

Check operating system log files.

Identify other problems (startup$shutdown, disks and operating

systems, database, operational R$%, performance).

Startup and shutdown problems (R/3 and application servers)

&. Check processes or ser'ices at operating system le'el.

. Check whether database is up.

%. Check connection with database (i.e., tnsping, R%trans d).

*. Check whether file systems are full.+. Check for network problems in the ser'er network.. Check backup log for problems after backup.

-.Check for problems after system crash.. Check for problems with P/C file ser'er.
