Performance BPM

Hi gurus,
We have created an integration scenario with 3 services. We've created an ABAP and JAVA Dynpros in order to consume them. Everything runs OK and the entire runtime is 10 seconds.
We've generated a BPM to orchestrate it's execution (this BPM will bethe one which executes the three of them). In order to consuming this BPM we've created an ABAP and JAVA Dynpros. Everything runs OK and the entire runtime is 35 seconds.
Does anyone knows the meaning of this difference on the performance time?
We are the only one working on this machine.
The BPM is simple:
Start-BAPI1-BAPI2-BAPI3-End
Kind Regards

HI,
Yes i agree with Ahmad,try to avoid BPM. If you want use BPM then use the New transaction in transformation step.see the below links

How do I get itunes to show BPM for all songs?

how do I get itunes to show BPM for all songs?

McChris,
The BPM field can be viewed, but it is almost always empty unless you have taken steps to populate it.
You can use a 3rd party tool to perform BPM detection and add it to your iTunes database:

IDOC to PI to MDM

Hi,
We have scenario like IDOC to MDM
where we are sending 10000(records) IDOCS to MDM. so please let me know design concerns for this w.r.t performance, BPM and mappings and also best practices .
Questions like :
1. what is the best way to receive all these 10000 IDOCS from SAP at a time and send it to MDM.
2. What is best practises to send these IDOCS from SAP to PI.
2. Does any chance to effect PI server crashes while we process 10000 IDOCs at a time? Pls. include all best practices for this scenario?
3.What mappings should I use here? Is this multi mapping required while handling IDOC to MDM graphical mapping? Then how?
We are using SAP standard IDOC(HRMD_A) and PI is 7.0
Thanks,
Shankar

Hi,
1. what is the best way to receive all these 10000 IDOCS from SAP at a time and send it to MDM.
Not advisable to trigger 10,000 Idocs at the same time.
2. What is best practises to send these IDOCS from SAP to PI.
Might be sending batches of 300-500 IDocs will be a good idea.
2. Does any chance to effect PI server crashes while we process 10000 IDOCs at a time? Pls. include all best practices for this scenario?
Well, it completely depends on your server configuration and hardware. But as I mentioned earlier, it's not advisable to trigger that many IDocs at one-go.
3.What mappings should I use here? Is this multi mapping required while handling IDOC to MDM graphical mapping? Then how?
It depends whether there is any requirement of using Multi-Mapping. If there is no special requirement, and you just have to pass the messages through PI, then use simple graphical mapping.

How do I get itunes to show what I last played?

Itunes used to show a date when I last played a song. This was very useful for audio books but since one of the updates it is no longer visible. Is it possible to switch it on?

Oracle BPM 11.1.1.5 Performance issues

Hi,
I have 2 Node Cluster of Oracle SOA 11.1.1.5 installed. Have a separate cluster for SOA/BPM, BAM, OSB, WSM. Here are the OS and Java versions
Java Vendor: HP
Java Version: 1.6.0.14
OS: HP-UX
OS Version: B.11.31
Running into an issue where Oracle BPM is performing very slow the task forms takes forever to come up and performing any actions takes too long to proceed som time it keeps timing out. I have over 100 SOA Process running plus some BPM Process but BMP Workspace application is running too slow as have customized tasks forms. But the same works a bit better in other instance which is non-clustered. Any idea what can be done on the server level to get around the performance issues. So far have modified Audit Levels and reduced soa-infra bpm log have the following settings in setDomainEnv.sh for USER_MEM_ARGS=-Xms2000m -Xmx6000m -XX:PermSize=1000m
But not help. Any idea what else to look into to get around these bpm performance issues. Here is what I have in setSOADomainEnv.sh

After changing JVM settigns for soa cluster it's a bit better but still slow so wondering what other tweaks can be done on the JVM side. Here is what is for the SOA Cluster
USER_MEM_ARGS="-server -Xms12928m -Xmx12928m -XX:PermSize=3072m -Xmn3232m -XX:+SXTElimination -XX:+UseParallelGC -XX:+UseParNewGC -XX:+ExplicitGCInvokesConcurrent -XX:-TraceClassLoading -XX:-TraceClassUnloading"
We are running multiple instances on the same boxes and the total RAM on the machine is 95 GB on each box which is being shared across 4 cluster environments. For now other 3 cluster environments have the SOA Cluster JVM setting as
USER_MEM_ARGS="-server -Xms4096m -Xmx4096m -XX:PermSize=1024m -Xmn1152m -XX:+SXTElimination -XX:+UseParallelGC -XX:+UseParNewGC -XX:+ExplicitGCInvokesConcurrent -XX:-TraceClassLoading -XX:-TraceClassUnloading"
Any help on what else I can tweak or set in JVM to get a better performance.
Thanks

Performance tuning in objects involving Integration process (BPM)

Hi,
We are facing a performance problem in one of our objects having integration process. The messages are getting processed sequentially instead of parallel processing within the integration process. As a result, the messages are getting queued up in the queue waiting for processing. Thus by the time all messages get processed, the time taken would have been alarmingly high. There is no correlation involved in the int process. My questions are
1. Is there any performance related best practices/checklist/config steps available for BPM related implementation. If so, please furnish/provide the links if any.
2. If it is not related to BPM , but related to tuning up of the queues, please provide the guidelines for queue tune up.
3. How to ensure that the messages are processed in-parallel within BPM ?
Regards
Ganesh

Hi,
Am not sure whether this would help you. By any chance did u use For Each instead of Par For Each.
Cos, when u use For each in an container step, all messages would be processed sequentially.
Do let me know if it helps you!

Performance of jdbc mapping lookup vs BPM Process

Hello fellow consultants,
I have project on AEX upcoming and now I`m deciding the strategy.
I have to implement few processes for which I will use BPM. But inside these processes I have few jdbc calls for logging to the oracle db.
Regarding the performance - what is better approach?
make these jdbc calls as a jdbc lookup in mapping
perform it as a regular part of bpm process
Thank you for suggestions
VB

Hi VB,
I have a different opinion than Fouad although I can understand his point, but for me, lookUps are rarely good and well implemented and it should be used in a very specific, required and critical scenarios. This is because this lookUp connection is not manageable, out of monitoring stuff and I don't think in the mapping step is the correct moment to open a JDBC connection with partner all of sudden.
My Idea is more for the point number 2, where you have everything well explicit step by step, opening the connection being manageable, with monitoring even though it may bring one or two steps more to your BPM but I'm more concerned at this moment to follow the best practice of integration and thinking in Performance I don't think there will be a gain that would justify the JDBC Lookup.

Diego

BPM - Process Performance Indicators and Process Monitoring

Hi,
In SAP BPM, is there any way to get some reports or dashboard with key PPI (Process Performance Indicators). What we are really interested in is to know how many times a month a process or a specific task of a process has been run, how many time it took to complete the task, was the task completed on time, where are we in the process right now, etc?
We have just started to look into SAP BPM, but my first impression is that it is more a modeling tool along with some taks coordinations. I feel like it's missing the key analytics to really drive innovation in our processes.
Probably that I'm wrong and I've missed something. Please let me know if there is a way to do that, if there are any workarounds or if there are any SAP partners that offer a solution that we could use along with SAP BPM.
Thanks a lot!
Martin

Thanks for your feedback.
We want to implement a SAP BPM scenario in a finance process for the VAT Tax reporting. So basically, our accountant needs to run some SAP transactions along with some manual outside steps. Then the supervisor will perform some checks and finally the tax manager needs to approve it.
There is some interactions with SAP but only for a small part of the process. What we want to achieve is to be able to see the key performance indicator for our process. But at the moment this is not delivered with SAP BPM. I've heard that this may come in the next release end of 2009, but in the meanwhile I'm wondering if other people have been able to implement some customization in Net Weaver or have found other alternatives to be able to monitor their process adequately.
Thanks
Martin

Performing simulation in BPM Composer

Hi Guys,
Any one having idea of how to perform simulation in BPM Composer?
Thanks in advance.

You're right, I restarted the server again and again...
I have just opened the sr in metalink, it has been confirmed as a bug. Unfortunately there's no way to workaround. What I can do now is waiting for the solution.

BPM Performance monitoring

Hi experts,
I would like to monitorize the performance of my BPMs. I want to know how much each BPM last. This information it's available in SXMB_MONI -> PE, there I can know that by watching to begining and end of each singular process. 1.-How can I achieve to watch this information for many processes? (RTWB??) I'm sending tests of 10, 100 and 1000 process so its not nice going to SXMB_MONI -> PE for each one.
By the way I'm having performance problems when sending a lot of them. 2.-Do you know if theres is any way of improve the performance? (like having a Queue of processes or similar)
Regards
Gonzalo

Goncalo,
This is what i did when i had to do a BPM perf analysis..just pasting my notes here...
1) go to moni, set your filters to find your complete roundtrip for the message..go to your outbound column, click on PE, Calculate the time difference between the first and the last entry..
Repeat this for several of the msgs to get a mean time..once you have a time..then you can start breaking down this into why and where its taking time...then analyze the bpm.
Check if any one particular step ..has the time it takes ..going up, check specifically the transformations..are they taking too much time..
Log into your xi server..run transactin ST03N, there switch to expert mode..filter in your time for the msgs...remember the user doing all this is always wf-batch..., Here you can analyze the load created by the bpe engine..
let me know if you need more info..

** Queue Performance in BPM scenarios

Hi friends,
How about the Queue performance when processing lot of messages at the same time ? For example, if 100 files are picked up and processed by BPM (at the same time), all files processed by the queue XBQO$PE_<Task> Ex: XBQO$PE_WS90000041and the result are delivered thru transaction queues ex: XBTOY0_<4 digit queue> .
My doubt is a) Will this slow performance when processing lot of files like 200,300 b) Is it required to increase any queue parameter ?
Kindly clarify, friends.
Kind Regards,
Jeg P.

Hey,
refer to the link for the performance issues.
/people/swen.conrad/blog/2006/12/22/xi-ccbpm-performance-under-perform-or-out-perform
If you think the performance is slow then you can go for multiple Queues.
refer to this link for the configuration of multiple Queues.

SAP XI BPM Performance and statistics

Hello all,
I am currently working on an integration using the BPM process within XI. During our initial testing, we noticed that, when it comes to the BPM process, XI takes too long to process a message. The actual size of the payload is really small and there is not much to the BPM process.
For example, I create one BPM process that takes a message and splits the message into separate documents for each target application and pass it on to another BPM process. The second process takes the message and changes its format to what is expected by the receiving application. It calls the target system and waits for a response.
Sender     Recv'r     Begin       End        End - Begin
SAPPRG     Split     11:29:46 11:31:01 74.810089
Split     Route     11:35:11 11:35:17 6.312764
Split     Route     11:35:28 11:35:40 12.021294
Route     DW     11:35:49 11:35:59 10.71562
Route     MPR     11:35:50 11:36:00 9.579952
DW     Route     11:35:59 11:35:59 0.50343
MPR     Route     11:35:59 11:36:00 0.485403
     Total                0:06:14 1.907142533
We also noticed some gaps b/w a message been send and receive steps within XI. I would like to know if there is any statistics on XI performance when it comes to processing messages within the BPM process and/or some documentation on how to improve performance using BPM.
Please, advise
Thanks..

Hi,
Checklist to use BPM-
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/3bf550d4-0201-0010-b2ae-8569d193124e
Also refer this Performance tuning guide-
https://websmp106.sap-ag.de/~sapidb/011000358700000592892005E.PDF
If you are using Correlation etc, then try to use Local Correlation. SO that you can avoid the scope of the correlation to the entire process. By default it will be for entire process. Even you can make use Block step and try to group related steps and give the scope of the steps for the block.
Hope this helps,

How to Achieve Performance Tuning In BPM Studio

Please Tell me how to achieve performance Tuning in BPm Project . let me know do have any documentation for this .
Thanks in Advance .

*5. Group Automatic Activities in a Single Transactional Boundary*
When you have several automatic activities in a sequence, recognize this as a potential performance improvement opportunity. The default behavior of Oracle BPM is during each Automatic activity's execution:
1. Initiate the transaction
2. Read the work item instance's variable information from the Engine's database
3. Execute the logic in the Automatic activity
4. If no system exception occurs, commit the transaction and write the instance variable information back to the Engine's database
Many times you'll instead want to speed execution when there are several Automatic activities in a sequence. If three Automatic activities are in a sequence, then the four items listed above will occur three times. By grouping these into a single transactional boundary, instead of 12 steps you would have:
1. Initiate the transaction
2. Read the work item instance's variable information from the Engine's database
3. Execute the logic in the first Automatic activity
4. Execute the logic in the second Automatic activity
5. Execute the logic in the third Automatic activity
6. If no system exception occurs, commit the transaction and write the instance variable information back to the Engine's database
This grouping of Automatic activities into a single transactional boundary can be done in one of these three ways:
1. Create a Group around the sequence of Automatic activities (lasso the three activities) -> right mouse click inside the dotted line -> click "Create a Group with Selection" -> click "Runtime" in the upper left corner -> click the checkbox "Is Atomic".
2. Instead of placing the Automatic actiivities in the process, add them in a Procedure and then call the Procedure from a new Automatic activity in the process.
3. In Oracle BPM 10g you can enable "Greedy" execution for the process by right mouse clicking the process's name in the Project Navigator tab -> click "Properties" -> click the "Advanced" tab -> click the "Enable Greedy Execution" radio button.

Question on BPM performance

Hi all
We have two source systems and data will be correlated based on filenames. Scenario is working fine when I test with small amount of file. But as per my interface specification, there might be quite big file (around 25mb) file come in a day. This instance BPM is showing as processing ( clock) symbol even though two files have been received. I noticed that, message is being processed at transformation step for long time. Can any one suggest me how do I handle this case. Can we increase queue size in BPE. All settings are fine in IE admin.
Thanks

Hi Yadagiri,
Your BPM is stuking in the transformation step in it, so increasing the queue size in BPE engine will not help.
Since you have to process large data through your scenario and you are using transformation step in your BPM, so in your mapping,that you are using in transformation step, you need to take care of mappping performance. Your java code in UDF, if any, must be efficient enough. There should not any statement in it that has impact on performance.
