Solution Manager too Slow

[Former Member]

Dear All,

We are running SAP Solution Manager 7.01 on Oracle 11g in AIX.

This central Solution Manager system is connected to more than 150 satellite systems.

The response of the system is too slow while we take transactions like solman_workcenter, RZ20 etc.

Is this because the system needs to fetch/collect infromation from all these 150 satellites before preseting the screen.

Solman is running with 10 CPU, 50 GB RAM and 82 GB swap.

The portal pages in the transactions takes more time to load.

Could you please help me to pin point the bottle neck in the system.

Regards,

Kiran

Hi,

Basically with 150 systems you may experience network capacity issue.

It does not matter if the system is the Solution Manager or any other SAP system. The analysis start from inspecting the overall time distribution by using the /nSTAD, then depending on the outcome check persistency, remote communication and locking with ST05 .

If in STAD there are huge wait times then definitely the network capacity should be inspected with OS-level monitoring tools, same for the CPU, memory and disk.

Regarding the java side views, it is very important to inspect the java side performance using the JDSR statistics in NetWeaver Web Administrator. There you would see the java side resource consumption to localize a potential memory consumption or CPU related issue. It is very important to clarify if the bottleneck is not the Garbage collection in java - if that is the case, the heap size parameters need to be tuned.

Hi ,

does the page: http://server:port/logon/logonServlet also need a long time to load?

How is your setup? Cluster? Any load (3rd-party) balancing solution in between the browser and the server? Some rule configured for /irj/portal on the load balancer / proxy?

Hi,

We donot have any third party tools or rules set.

Currently the analysis from ST03 shows high average processing time (18,288 ms) for AUTOABAP.

There are slight swaping in SAP buffers.

The system is running with 50GB RAM and 80GB swap configured.

We have around 140 system connected via CCMS agents to this solution manager system for monitoring.

While taking solman workcentre or RZ21 transaction, the system is very slow with java pages.

There are no error in LAN and filesystem.

What all can be checked for high avg.processing time.

Hi Kiran,

We has same issue with our Solman system, after tuning oracle 11G recommended parameters, we are good.

Refer to the - Note 1431798 - Oracle 11.2.0: Database Parameter Settings.

Do you have update stats job for SOLMAN scheduled in DB13?

Hi Kiran,

There are many approaches to analyze this situation.

Look at the OS for histories of CPU, I/O, and memory Utilization.

Check the SAP profile parameters, especially ST02.

Analyze the abap and database runtimes in ST03.

Portal pages indeed take much longer time to load than ABAP screens.

Also look at the database for hit ratios.
