Hi,
When ABAP system gets down suddenly what are the logs files to check to find the root cause of the system shutdown and what is first thing to check in the system?Kindly,let me know the things as I'm new to SAP BASIS.Help me regarding this.
Thanks & Regards,
Sandeeep
Sandeep,
See if Work processes are running or not from task manager if it is windows or ps -ef in unix.
Check if database is up and running or not.
Then 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_w0,1,2 to see what happened in WP log.
Thanks,
Digesh Joshi

Hi,
The system can go down for various reasons, few are quoted below I can immediately think of.
-
OS level
check all SAP and DB file systems/ disk drives are available and visible.
Check the file systems are not full especially the oracle archive logs, datafile, sapdata.
Check the dev_*, files and take a backup of these files as they would become *.old files after an attempt to startup SAP.
Check the process of SAP are running dw* or disp+work
If you are not able to connect through sapgui - check through the cmd prompt or os prompt the dpmon if some work process in SAP are running or in stopped status.
Check if the R3trans -d connect is succesful, if not then db connectivity is an issue.
*check OS system logs, event viewer(system & application) if there is any significant ones.
check if your cpu, memory usage is not abnormal and not reaching 100% levels.
check if you are able to ping the host and if the network connectivity between server and user location is not the problem.
-
DB Level
Check the db service is running or the process is running (pmon, ora*)
check the db alert logs for any problems there such as any corruption, recovery.
check the db connectivity using basic tests.(sql connect)
-
SAP Level
Check all application servers are running and it might be if one app server is down.
