Poor performance - network time / RFCs etc.

Former Member — Mon, 09 Feb 2009 16:07:29 GMT

Hi SAP Colleagues

I am trying to improve performance on our ECC / Portals system for remote users and when tracing on the backend ECC6 systems, I can see a lot of lost time around the activity RFC/coms activity. Specifically, I can see that around 3.5 minutes was 'lost' between the following components. I am trying to find a technical explanation so that I may address any specific area which could help me diagnose. For example, does (or indeed could) this point to a problem with RFCs or with the network? If that is the case, does anyone have a useful nect step (e.g. delete old RFCs)...

Any assistance would be gratefully received.

Regards

Des

Hi There,

You can give a go with following options:

1. Select low speed connection option in SAP gui while login to SAP system.

2. Make use of appropriate application server.

Hope this helps.

Hi Des,

We have similar problem in our setup, ABAP trace shows lots of time spent on Client OLE_FLUSH_CALL. Did managed to resolve this issue in your system.

It would be gr8 if you can share your thoughts.

Hi ,

We have a similar issue when accessing Interactive forms from the portal through an ABAP webdynpro. The trace that was run identified OLE_FLUSH_CALL and SESSION_MANAGER as taking the maximum amount of time when trying to display any data from the webdypro in portal.

When trying to Debug this, I did not find that the webdynpro was directly calling OLE_FLUSH_CALL. However OLE_FLUSH_CALL was in fact called from a standard program RSTPDAMAIN.

Could anyone shed some light on how we can check where OLE_FLUSH_CALL is actually getting called from as the call stack does not actually lead back to the webdynpro at all.

Kindly go thru below sap notes

Note 1178342 - COMMUNICATION_FAILURE is caught in OLE_FLUSH_CALL

Note 1525520 - STM: performance optimization in loan master data

Note 1241984 - Exception GUI_NO_MODE_AVAILABLE for RFC, destination SAPGUI

Hi,

all notes are already implemented. Nevertheless we still use seconds with OLE_FLUSH_CALL... Any ides what else we could analyse?

THere is a known issue with OLE_FLUSH_CALL performance in SAPGUI 720.

This has been solved with 730 SP01.

Could you try to adress your performance issues <by upgrading the SAPGUI to latest avail ?

Hi Aidan,

I've already updated my SAP GUI to 7.30 SP2 but issue with OLE_FLUSH_CALL still exists.

It happened in webdynpro application of Solution Manager. OLE_FLUSH_CALL net time (%) is over 90 in ST12 trace analisys.

Hello guys,

did you find a solution for this? I also encountered this issue in SAP CRM 7.

Thanks and kind regards

This problem can being due the Progress indicator enabled rolling in remote connection. Normally assigning to user the parameter SIN = 0 it minimizes this behavior do not issuing the progress indicator by network.
