Monitoring SAP work processes via OS command

Have you ever experience the condition where all SAP dialog work processes are in used? Then we can just do nothing except to restart the SAP system 🙂

I found an interesting tool, binary executed, provided by SAP, that can manage the above condition.It’s called dpmon.

With dpmon, we can still monitor the SAP work processes in OS level environment. No need to logon to SAPGUI.
Just logon at the OS level as user <sid>adm and go to SAP profile directory.

These are examples using Solaris and windows environment.

On Windows:
E:
cd E:\usr\sap\CRD\sys\profile
dpmon pf=CRD_DVEBMGS01_JKTGRHXSAPC1

On Solaris:
cd /sapmnt/EXX/profile
dpmon pf=EXX_DVEBMGS01_sapprod

Dpmon has several functionalities the same as transaction SM50 via SAPGUI.

With dpmon we can stop workprocess, kill workprocess, or enable restart flag.

There’s an online video of e-learning, explaining on this dpmon tool:

Q&A About SAP Spool

Q: How do I restart the spool work process without restarting the SAP application?
A: You can use the transaction SM50. Choose the spool work process then select “proces → cancel without core”.
If you selected “restart after error → yes”, workprocess will be restarted and you will see the the error colon will get a red status.

Q: Can I switch other work processes to spool work processes without restarting the instance?
A: No. The internal structure of spool work processes is different from, for example, dialog work processes. Therefore, if you want to change the number of spool work processes, you must do this in the context of SAP profile maintenance (transaction RZ10) and then restart the instance.
