At their booth at TechEd 07 in Las Vegas, IBM demoed updated transactions for Basis and other SAP experts to view the underlying  hardware performance of a virtualized environment, as well as the totally cool transfer of a live running SAP system and database from one node to another, without user session interruption.  The system was running in Walldorf, and the control/display was in Nevada, USA!


ST06/OS06 is the local  operating system monitor, where you view the CPU, memory and other metrics  collected by an SAP software agent (saposcol) on an immediate or short history  period.  One of my mandates in visiting TechEd this year was to get ideas for better  solutions to the collection, storage and use of this data in both long term  capacity planning scenarios as well as immediate escalation issues.   See my ST10 blogfor an example of where we need this capability.


The problem with the  “old” ST06 is that it uses granular system resources that don’t exist any longer  in a virtualized environment, so if I see 90% CPU usage that might not be a bad  thing.


The screens we saw were for SAP 7.0,  so my next challenge will be how to connect our older systems via agents to a  newer system (maybe Solution Manager 4.0) to provide this information  before we upgrade.

SDN forum:


I found one SDN forum Virtualization on AIX 5.3 and above with SAP on the topic of OS metrics in virtualized environments.



OS07N ST06N OS06N, all lead to the same target.
Details are described in the SAP note 994025.
Agents to monitor older SAP versions are available down to 4.6 D kernel based systems. 
The central display needs to run on an 7.0 based system [correction: central display can run on systems 6.20, 6.40 or 7.0 based, as described in Note

Screen shots and research into our systems:

The newest SAP installation we are running is Solution Manager 4.0, so I used this to try to find the transactions as shown.  Alas, while we have a 7.00 system, we are not up to the patch levels required in the Basis, kernel and agent versions.  We are on PL 10, and need to be on PL26!?

However, there are notable differences from our 6.20/6.40 systems.  The most obvious is the change from flat screen displays to ALV grids.  Less useful is that we are missing some of the column titles, and one appears to be in German (“stunde”).  Time to patch!
