How to determine SAP system is up and running

How to ensure the SAP system running status and common issue that the system was not responding

When there is a situation where the users complain that they're unable to login into the SAP GUI.

As Basis administrator, the first step on diagnosing the problem is to check whether the SAP system is running and ensure the disk space is not full. Common issue of system not responding was due to the "oraarch" disk space is full and hang the system.

The sample system shown is running in HP-UX

Steps:

Ensure the SAP system and database is up and running

1) Login to the OS command and execute: ps -ef | grep gwrd*. If the system is not running you would not see any of the details of the <SID>adm.

2) Execute: ps -ef | grep ora*. Again if the system is not running you would not see any of the details of the <SID>adm.

Ensure there are enough hard disk space for the system

1) The common issue of system not responding was due to the "oraarch" folder was full

2) If the folder was full, backup and remove the files and the system should back to normal.

 * always perform backup of the files in the oraarch folder before deleting it, as it will be use for Oracle recovery process. If the files were deleted you would not be able to perform restore to the last recovery point.
