Your SAP System hang? Here some list you have to check:
1.Can you access your SAP?
- If yes, check SM21 for problem log
- check SM13 for update deactivated
- check SM50/SM51 for workprocess full
- check DB02 for some full table/tablespaces if you don’t activate autoextend.
2. If you can’t access SAP,
- check for filesystem full (usually archiver full), check it from your operating system
- check CPU/memory usage
- check for listener service, up or not
UNIX Only:
– check whether there are two listener services running or not, kill one if any.
