SAP Connector Factory - performance tuning in VA

Is anyone aware of SAP guidance or notes on how to tune the SAP connector SAPFactory properties, especially where a Portal makes RFC calls across multiple ABAP-based backends?  For example SAP Note 1021921 shows this property is important when closing backend BI RFC sessions as they are not terminated by the DSM.
Visual Administrator
Services -> Connector Container
Runtime -> Connectors -> Connector 1.0 -> sap.com/com.sapportals.connectors.sap -> SAPFactory
Managed Connection Factory -> Connection Definition
Connection Lifetime
Cleanup Thread
Max Connections
Max Time to wait for Connection
In our environment we have CRM, BI and ECC backends.  Thanks!

  • SAP Business Objects Performance Tuning Guides

    Hello everyone,
    I'm currently looking for Performance Tuning guides for the hardware/software. In particular, parameters for the hardware. I'm having a hard time finding any kind of guides on the server side of Business Objects. So I'm wondering if anybody knows of some that are available on the internet or SAP site?
    I've found very few in the software department. However, I'm looking more for the hardware portion of Business Objects. Basically the goal is to get the server as optimal as possible (As far as memory, parameters, CPU, etc) is concerned so we know it can't be a hardware issue. It's kind of narrowing down the potential problems we can have later on down the road so that's why this is very important right now.
    Any help with this will be greatly appreciated. Thanks in advance. -Victor

  • SAP Web services performance tuning in terms of concurrent users?

    Hello,
    we in our organisation are planning to build a web portal which can connect to our sap environment and perform various tasks.
    Hence to find out the performance capabilities we exposed some web services from SAP end and did a load test on the same.
    The test results were not promising, with only 25 concurrent users the response time was as high as 12 seconds.
    Now we need to fine tune the SAP web service module to get the max performance.
    Can anybody point us in the right direction?

  • SAP Netweaver Performance Tuning

    Guys,
    I am good in SAP J2EE Engine Performance Tuning. I would like to learn SAP ABAP Based Server Performance tuning end to end. Please recommend me some links/docs to start with the performance tuning for different OS like HP-UX/AIX & for Databases : Oracle/MaxDB etc.
    Thank you in advance.
    Cheers, Karthick

    Hi Karthick, for example for SAP with Oracle on AIX -->
    white paper -->
    http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP100377
    But SAP with Oracle tuning are usually not very much dependent on the platform, of course there are differences but they are not much.
    Personally, I bought the SAP Performance Optimization Guide -->
    http://www.sap-press.com/products/SAP-Performance-Optimization-Guide-(5th-Edition).html?
    and SAP Database Administration with Oracle

    or how can I view the performance of the integration process ? or exactly how performance tuning is done.
    pls help,
    Best regards,

    Hi,
    SAP Note:
    Symptom
    Performance bottlenecks when executing integration processes.
    Other terms
    ccBPM
    BPE
    Performance
    Integration Processes
    Solution
    This note refers to all notes that are concerned with improving the performance of the ccBPM runtime.
    This note will be continually updated as improvements are made.
    Also read the document "Checklist: Making Correct Use of Integration Processes" in the SAP Library documentation, on SAP Service Marketplace, and in SDN; it contains information about performance issues to bear in mind when you model integration processes.
    Refer to the appended notes and maintain the default code changes by using SNOTE, or by importing the relevant service packs. Note that some performance improvements cannot be implemented by using SNOTE and are instead only available in service packs.

  • SAP CRM Performance tuning

    From where can I get information or documents how to do performance tuning in SAP CRM?

    Hi, Performance Tuning a SAP system is unique in every environment, also there are many area's in SAP to tune even area's outside SAP, eg... your Operating System/Network/Client Machines/Virtual Landscape/Cloud.
    I recommend that you engage in a performance testing execise which will identify what area of your SAP Landscape needs tuning, first you need to identify the bottleneck before you can tune it.
    The way the question was posed is exactly the same as wanting to fix a car but you have no idea which part of the car to fix...

  • In sap bi performance tuning option is considered in cube not in ods, why?

    details about
    indexes,partitions,aggregates,compression,roll up
    how these are helping to increase system performance
    why ods is not suitable?

    Hi,
    Generally we do performance tuning on the cubes as most of the reportings are done on the cubes hpowever in case of DSO also we can increase the performance by creating indexes of deactivating SID generation flag if there is no reporting on the DSO.
    Following 2 links will show you different aspects of performance tuning :-

    You may create aggregates on the cube if some of  IO are being used in the query very frequently to enhance the performce of query execution.

    Hi All,
    Just thought of sharing this info on SDN...
    A new book on SAP BW Performance Tuning is available...
    http://www.erpguides.com/books/bwperformance.htm
    Shreekant W Shiralkar & Bharat Patel have authored a book on SAP BW Performance Tuning. The book is based on their real life experiences on improving the system performance using various features/techniques/ideas.
    I am aware that the The book covers many how-to procedures with screen shots for helping the reader to implement the performance improvement and benefit immediately. It would be interesting to read this book as a compilation of practical experiences on performance tuning .

    Hi,
    Read Data warehousing books written by Ralph Kimball or Bill Inmon in order to familiarize yourself with the basic concepts of data warehousing. This is the foundation of the entire thing.
    Follow the SAP training materials on BW Data Warehousing, BW Reporting and BW Modeling. There are several books that can help you a lot when getting started. check this link
    [http://www.amazon.com/SAP-BW-Book-List/lm/RRWM7R55RBEXQ/ref=cm_lmt_srch_f_2_rsrsrs2/103-7157721-8001426]

  • SAP Performance tuning

    What measures shall we take if it is needed to performance tune the SAP Server. It is getting too slow. It will be helpful if someone can send me some link about SAP Performance tuning, not ABAP performance tuning.
    Regards,
    Subhasish

    The SAP Servers can be slow because of many reasons:
    1. The Table Consistency: The tables should be consistent. A consistency check should be done regulalrly.Better would be using DB13 so that it can be scheduled in appropriate days.
    2. One major reason that I have found in recent times is the amount of authorizations that might be available to the users of the sytem. If all the users have a high volume of authorization objects in their user master buffer, then the response time becomes sluggish.This is true for most of the dev boxes that allow almost any amount of authorization for users and have a low RAM size.
    3. Also you might be intrested to check your network consistency. If you are accessing your servers from home with a wireless connection of 16kbps, you might want to configure your logon pad for such a crappy connection.
    Most of the BASIS performance tuning tasks such as ST04, STAT, ST02 and DB12 should be carried out too just to investigate furthur.
    Hope these were a few helpful tips.
    Peace be with everybody
