what all checks will you perform when sap is down

Answer Posted / deepak balhara

Basically we have the following 4 types of check

1. Hardware check
2. R/3 check (with application servers)
3. OS check
4. Database check

1. Hardware check
Check console messages
Check hardware components
Check main log files
Start up/shut down log files
Check the disk space

2. R/3 check (with application servers)
Check for problems with PDC file server.
Check processes or services at operating system level
Check connection with database
Check the buffer size and disk capacity

3. OS check
Check the event viewer

4. Database check
Check database specific error log file
Check database error numbers
Check database alerts.

If you are using P550 and P570 from IBM, please restart the
application server without restarting the database server...
