Business Process Performance Tuning

Hi Pals,
I would like to request your help and inputs regarding tuning performance of Business process for my scenario.
I have created a synchronous Process with 3 message mapping transformation steps. ( inbetween Sync Receive and Sync Send steps). So its pretty simple process.
I am able to execute only 3500 processes per hour.
The SAP Netweaver Server m/c configuration is 2 dual core processors with 12 GB RAM.
Business process - Without buffering with multiple queues (content specific).
IE Logging - No sync logging, logging level - 0 ( so logging turned off )
I have tried out all the configurations mentioned in below weblogs, but with very less improvement in my case.
Performance Tuning Checks in SAP Exchange Infrastructure(XI): Part-III
Performance Tuning Checks in SAP Exchange Infrastructure(XI): Part-II
Performance Tuning Checks in SAP Exchange Infrastructure
I think something else is choking the execution, as the CPU or memory usage is not more than 10-20%.
Please pour in your inputs.
Thank you!
Best Regards,
Saravanan N

Thank you very much Bhavesh!
In my BPM, all the steps are set for "No New Transaction". So as to avoid any performance issue. But there is no improvement.
Even I have deleted all the work-items from Trxn: SWWL before the test.
From ST03N, for each process instance executed, four function modules takes the maximum time.
Function Module--No. of Calls--
Execution Time/RFC Call
TRFC_QIN_DEST_SHIP-- 1--
995 milliseconds
TRFC_QIN_ACTIVATE--1--
1077 milliseconds
ARFC_DEST_SHIP--2--
280 milliseconds
ARFC_RUN_NOWAIT--2--
402 milliseconds

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

Hi Prabha,
Aggregate Definition :
An aggregate is a materialized, aggregated view of the data in an InfoCube. In an aggregate, the dataset of an InfoCube is saved redundantly and persistently in a consolidated form on the database.
Use
Aggregates allow quick access to InfoCube data during reporting. Similar to database indexes, they serve to improve performance.
An aggregate is made up of the characteristics and navigation attributes that belong to an InfoCube. Characteristics that are not used in the aggregate are compressed.
Each component of an aggregate has to be assigned to a selection type. A selection type indicates the degree of detail to which the data in the underlying InfoCube is aggregated. You can choose one of the following selection types:
All characteristic values ("*"): The data is grouped by all values of the
characteristic or navigation attributes .
Hierarchy level (H): The data is grouped by the hierarchy level node. You can
also store values on the hierarchy levels of an external hierarchy .
Fixed value (F): The data is filtered by a single value .
For each InfoCube, you can set whether the aggregates of the InfoCube are compressed automatically when it is filled with data or after the roll up of data packages (requests).
1. You are in the Data Warehousing Workbench in the Modeling functional
area. In the InfoProvider tree, navigate to the required InfoCube.
2. In the context menu of the InfoCube, choose Manage.
3. In the lower part of the screen, select the Roll Up tab page.
4. Under the Aggregates group header, set the corresponding indicator in
the Compress After Roll Up field.
Standard Aggregation : This means how the key figure is going to be summarized normally for a specific set of characteristics .
Eg : Quantity across all the purchase items for a purchase Order
Exceptional Aggregation : You define how the aggregation should happen basing on a particular characteristic ( Usually time characteristic ) .
Eg : head count ( No of Employees ) in a organisation ..--> this should not be summarized on a daily basis..instead this should give a final value at the end of the month .
Aggregation is basically for keyfigures .
take a look at this doc, you will find all your answer:

Question1: how we will see the based on aggreagate what querys are running
I think "aggreegate maintance screen ---proposal -
query proposal" i am right ,if it is worng pls correct me?
Answer 1:
There are two tools that are used to analyze which aggregate is suitable for which navigation step.
You optimize the start screen of a query with the query Monitor (transaction RSRT) if you execute the function Execute + Debug.
With the trace tool (transaction RSRTRACE) you can draw several navigation steps, and process them again using the function DB Debugging (exact path: Transaction RSRTRACE > Goto > User Logs or All Logs > double-click on the log you want > DB Debugging).
Refer The OSS note 99010
Question 2: When i am creating a aggregate what charteristics we choose i mean based on report/some thing else?
Answer 2:
By refering the Statistical data and comparing the Proposed Aggregates we can create the aggregates.
The above RSRT and RSTRACE will be more useful tools to plan an Aggregate.

Reg: Process Chain, query performance tuning steps

Hi All,
I come across a question like, There is a process chain of 20 processes.out of which 5 processes are completed at the 6th step error occured and it cannot be rectified. I should start the chain again from the 7th step.If i go to a prticular step i can do that particular step, How can i start the entair chain again from step 7.i know that i need to use a function module but i dont know the name of FM. Please somebody help me out.
Please let me know the steps involved in query performance tuning and aggregate tuning.
Thanks & Regards
Omkar.K

Hi,
Process Chain
Method 1 (when it fails in a step/request)
/people/siegfried.szameitat/blog/2006/02/26/restarting-processchains
How is it possible to restart a process chain at a failed step/request?
Sometimes, it doesn't help to just set a request to green status in order to run the process chain from that step on to the end.
You need to set the failed request/step to green in the database as well as you need to raise the event that will force the process chain to run to the end from the next request/step on.
Therefore you need to open the messages of a failed step by right clicking on it and selecting 'display messages'.
In the opened popup click on the tab 'Chain'.
In a parallel session goto transaction se16 for table rspcprocesslog and display the entries with the following selections:
1. copy the variant from the popup to the variante of table rspcprocesslog
2. copy the instance from the popup to the instance of table rspcprocesslog
3. copy the start date from the popup to the batchdate of table rspcprocesslog
Press F8 to display the entries of table rspcprocesslog.
Now open another session and goto transaction se37. Enter RSPC_PROCESS_FINISH as the name of the function module and run the fm in test mode.
Now copy the entries of table rspcprocesslog to the input parameters of the function module like described as follows:
1. rspcprocesslog-log_id -> i_logid
2. rspcprocesslog-type -> i_type
3. rspcprocesslog-variante -> i_variant
4. rspcprocesslog-instance -> i_instance
5. enter 'G' for parameter i_state (sets the status to green).
Now press F8 to run the fm.
Now the actual process will be set to green and the following process in the chain will be started and the chain can run to the end.
Of course you can also set the state of a specific step in the chain to any other possible value like 'R' = ended with errors, 'F' = finished, 'X' = cancelled ....
Check out the value help on field rspcprocesslog-state in transaction se16 for the possible values.
Query performance tuning
General tips
Using aggregates and compression.
Using less and complex cell definitions if possible.
1. Avoid using too many nav. attr
2. Avoid RKF and CKF
3. Many chars in row.
By using T-codes ST03 or ST03N
Go to transaction ST03 > switch to expert mode > from left side menu > and there in system load history and distribution for a particual day > check query execution time.
/people/andreas.vogel/blog/2007/04/08/statistical-records-part-4-how-to-read-st03n-datasets-from-db-in-nw2004
/people/andreas.vogel/blog/2007/03/16/how-to-read-st03n-datasets-from-db
Try table rsddstats to get the statistics
Using cache memoery will decrease the loading time of the report.
Run reporting agent at night and sending results to email.This will ensure use of OLAP cache. So later report execution will retrieve the result faster from the OLAP cache.
Also try
1. Use different parameters in ST03 to see the two important parameters aggregation ratio and records transferred to F/E to DB selected.
2. Use the program SAP_INFOCUBE_DESIGNS (Performance of BW infocubes) to see the aggregation ratio for the cube. If the cube does not appear in the list of this report, try to run RSRV checks on the cube and aggregates.
Go to SE38 > Run the program SAP_INFOCUBE_DESIGNS
It will shown dimension Vs Fact tables Size in percent.If you mean speed of queries on a cube as performance metric of cube,measure query runtime.
3. --- sign is the valuation of the aggregate. You can say -3 is the valuation of the aggregate design and usage. ++ means that its compression is good and access is also more (in effect, performance is good). If you check its compression ratio, it must be good. -- means the compression ratio is not so good and access is also not so good (performance is not so good).The more is the positives...more is useful the aggregate and more it satisfies the number of queries. The greater the number of minus signs, the worse the evaluation of the aggregate. The larger the number of plus signs, the better the evaluation of the aggregate.
if "-----" then it means it just an overhead. Aggregate can potentially be deleted and "+++++" means Aggregate is potentially very useful.

http://help.sap.com/saphelp_nw70/helpdata/en/60/f0fb411e255f24e10000000a1550b0/frameset.htm
4. Run your query in RSRT and run the query in the debug mode. Select "Display Aggregates Found" and "Do not use cache" in the debug mode. This will tell you if it hit any aggregates while running. If it does not show any aggregates, you might want to redesign your aggregates for the query.
Also your query performance can depend upon criteria and since you have given selection only on one infoprovider...just check if you are selecting huge amount of data in the report
Check for the query read mode in RSRT.(whether its A,X or H)..advisable read mode is X.
5. In BI 7 statistics need to be activated for ST03 and BI admin cockpit to work.
By implementing BW Statistics Business Content - you need to install, feed data and through ready made reports which for analysis.

You can go to T-Code DB20 which gives you all the performance related information like
Partitions
Databases
Schemas
Buffer Pools
Tablespaces etc
use tool RSDDK_CHECK_AGGREGATE in se38 to check for the corrupt aggregates
If aggregates contain incorrect data, you must regenerate them.

Performance tuning of BPEL processes in SOA Suite 11g

Hi,
We are working with a customer for performance tuning of SOA Suite 11g, one of the areas is to tune the BPEL processes. I am new to this and started out with stress testing Hello World process using SOAPUI tool. I would like help with the below topics -
1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
2. Do we need to run stress tests for every BPEL process deployed?
2. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?
Thanks in advance!
Sritama

1. How do I interpret the statistics collected during stress testing? Do we have any benchmark set that can indicate that the performance is ok.
You need
pay attention to:
java heap usage vs java heap capacity
java eden usage vs java eden capacity
JDBC pool initial connections vs JDBC pool capacity connections
if you are using linux: top
if you are using aix: topas
2. Do we need to run stress tests for every BPEL process deployed?
yes, you need test each BPEL. You can use "Jmeter" tool.
Download Jmeter from here: Apache JMeter - Apache JMeter&trade;
Other tools:
jstat
jstack
jps -v
Enterprise Manager
WebLogic Console
VisualVM
JRockit Mission Control
3. Is there any performance tuning strategy documentation available? Or can anybody share his/her experiences to guide me?

Hi,
Think abt all BI is made up of an dhow to tune them..
Some hints:
1 Performance tuning for data loads : ( number range buffering, parallel loading..pseudo delta..chnging technical properties of tables if rec >100,000...IDOC clogging...etc)
2) Performnce tuing for Queries Aggregate...Cube modelling, OLAP cache....efficient multiprovider queries.etc.)
MEntion about transactiona whoich you will require for these things..such as RSRV..RSRTRACE..STO3n..ST05..etc...

GUID and business process and performance

The single object dialog is not the only business process which has to be solved. Much more important are the nextfollowing mass activities of each business process. Therefore it seems to be much more efficent to store data not with a GUID but with a logical key to improve the performance of access during those mass processes instead of collecting all data spread over a extra large file (secondary index is helpfull, but must pick it out too) .
- Are there any possibilities available to influence the data filing to logical aspects of the process.
- Are there any time comparisons made between logical filing and GUID filing in mass processes.
- Are there any tips when to use, when to avoid GUIDs for filing

Hi,
Both business publisher and process repository are available in CD2 of BPA Suite complete (for windows OS).
Important step before installing the business process repository is that you must have installed the database. Or else you must have installed BPA with OracleLite or XE database. At the time Business process repository installation you need to choose the database option 1 if Oracle enterprise data base is installed, else you may choose option 2 which says you already have BPA installed with database.

Business Process Management - End-to-End Analysis and Performance KPI's

Hello,
I am from WB and were looking to expand our footprint with Business Process Monitoring.
For critical business processes (order to cash, release to accounting, procure to pay; create shopping cart, etc.) how can be map and determine for the business units the expected run times as well as capturing / reporting historical trend analysis; looking at from a company business process level and not an SAP transaction level.
We were disappointed that we were unable to find this detailed functionality in SolMan (dashboards, metrics, customizable reports, etc.) that could tell us how long a WB business process takes to execute form start to finish.
Does anyone have any info as to if NetWeaver BPM can capture and trend the complete A-Z run times of a Business Process?
Iu2019m I missing something here?! I would think something this basic would automatically be a part of SolMan BPM Monitoringu2026
Appreciate all and any feedback.

Performance tuning in PL/SQL code

Hi,
I am working on already existing PL/SQL code which is written by someone else on validation and conversion of data from a temporary table to base table. It usually has 3.5 million rows. and the procedure takes arount 2.5 - 3 hrs to complete.
Can I enhance the PL/SQL code for better performance ? or, is this OK to take so long to process these many rows?
Thanks!
Yogini

Can I enhance the PL/SQL code for better performance ? Probably you can enhance it.
or, is this OK to take so long to process these many rows? It should take a few minutes, not several hours.
But please provide some more details like your database version etc.
I suggest to TRACE the session that executes the PL/SQL code, with WAIT events, so you'll see where and on what time is spent, you'll identify your 'problem statements very quickly' (after you or your DBA have TKPROF'ed the trace file).
SQL> alter session set events '10046 trace name context forever, level 12';
SQL> execute your PL/SQL code here
SQL> exitWill give you a .trc file in your udump directory on the server.

Also this informative thread can give you more ideas:

as well as doing a search on 10046 at AskTom, http://asktom.oracle.com will give you more examples.

Performance tuning in EP6 SP14

Please point me to some good clear documentation related to performance tuning. Better yet, please tell me some things you have done in your EP6 portal to improve performance.
Any help is greatly appreciated.

Hi
In general we have experienced that NW04 is faster than earlier versions.
One of the big questions is if the response time is SERVER time (used for processing on the J2EE server), NETWORK time (latency and many roundtrips), CLIENT time (rendering, virus-scanning etc) or a combination.
1) Is the capacity on the server ok? CPU utilization and queue lenght high? Memory swapping?
2) A quick optimazation server-side is logging: Plese verify that that log and trace levels are ERROR /FATAL or NONE on J2EE and also avoid logging on IIS and IIS proxy is used
3) Using a HTTP trace you can see if the NW portal for some reason generetes more roundtrips (more GETS) that the old portal for the same content - what is the network latency? Try to do a "ping <server>" from a client pc and see the time (latency) - if it is below 20 ms the network should do a big difference.
4) On the client try to call the portal with anti-virus de-activated if the delta/difference in response times are HUGE your client could be to old? (don't underestimate the client). Maybee the compression should be set different to avoid compres (server) and uncompres (client) - this is a tradeoff with network latency however.
Also client-side caching (in browser) is important.
These are just QUICK point to consider - tuning is complex

Performance Tuning in IR

Hello All,
We have created some reports using Interactive Reporting Studio. The volume of data in that Oracle database are huge and in some tables of the relational database are having above 3-4 crores rows individually. We have created the .oce connection file using the 'Oracle Net' option. Oracle client ver is 10g. We earlier created pivot, chart and report in those .bqy files but had to delete those where-ever possible to decrease the processing time for getting those report generated.
But deleting those from the file and retaining just the result section (the bare minimum part of the file) even not yet helped us out solving the performance issue fully. Still now, in some reports, system gives error message 'Out of Memory' at the time of processing those reports. The memory of the client PCs,wherefrom the reports are being generated are 1 - 1.5 GB. For some reports, even it takes 1-2 hours for saving the results after process. In some cases, the PCs gets hanged at the time of processing. When we extract the query of those reports in sql and run them in TOAD/SQL PLUS, they take not so much time like IR.
Would you please help us out in the aforesaid issue ASAP? Please share your views/tips/suggestions etc in respect of performance tuning for IR. All reply would be highly appreciated.
Regards,
Raj

SQL + & Toad are tools that send SQL and spool results; IR is a tool that sends a request to the database to run SQL and then fiddles with the results before the user is even told data has been received. You need to minimize the time spent by IR manipulating results into objects the user isn't even asking for.
When a request is made to the database, Hyperion will wait until all of the results have been received. Once ALL of the results have been received, then IR will make multiple passes to apply sorts, filters and computed items existing in the results section. For some unknown reason, those three steps are performed more inefficiently then they would be performed in a table section. Only after all of the computed items have been calculated, all filters applied and all sorts sorted, then IR will start to calculate any reports, charts and pivots. After all that is done, the report stops processing and the data has been "returned"
To increase performance, you need to fine tune your IR Services and your BQY docs. Replicate your DAS on your server - it can only transfer 2g before it dies, restarts and your requested document hangs. You can replicated the DAS multiple times and should do so to make sure there are enough resources available for any concurrent users to make necessary requests and have data delivered to them.
To tune your bqy documents...
1) Your Results section MUST be free of any sorts, filters, or computed items. Create a staging table and put any sorts or local filters there. Move as many of your computed items to your database request line and ask the database to make the calculation (either directly or through stored procedures) so you are not at the mercy of the client machine. Any computed items that cannot be moved to the request line, need to be put on your new staging table.
2) Ask the users to choose filters. Programmatically build dynamic filters based on what the user is looking for. The goal is to cast a net only as big as the user needs so you are not bringing back unnecessary data. Otherwise, you will bring your server and client machines to a grinding halt.
3) Halt any report pagination. Built your reports from their own tables and put a dummy filter on the table that forces 0 rows in the table until the report is invoked. Hyperion will paginate every report BEFORE it even tells the user it has results so this will prevent the user from waiting an hour while 1000s of pages are paginated across multiple reports
4) Halt any object rendering until request. Same as above - create a system programmically for the user to tell the bqy what they want so they are not waiting forever for a pivot and 2 reports to compile and paginate when they want just a chart.
5) Saved compressed documents
6) Unless this document can be run as a job, there should be NO results stored with the document but if you do save results with the document, store the calculations too so you at least don't have to wait for them to pass again.
7) Remove all duplicate images and keep the image file size small.
Hope this helps!
PS: I forgot to mention - aside from results sections, in documents where the results are NOT saved, additional table sections take up very, very, very small bits of file size and, as long as there are not excessively larger images the same is true for Reports, Pivots and Charts. Additionally, the impact of file size only matters when the user is requesting the document. The file size is never an issue when the user is processing the report because it has already been delivered to them and cached (in workspace and in the web client)
