Prstat -J cmd takes more time if there are around 800 processes & 300 user

Hi experts,
We used command 'prstat -J -n 1,100 -z global 1 1' to obtain the project statistics.
One of my customer who have around 800 processes with around 300 users facing problem on his machine whenver the above prstat command executed. As per his comments 'prstat' consuming high CPU and it taking much time to execute.
He has using machine with following configuraton:
SunOS <machine name> 5.10 Generic_120011-14 sun4u sparc SUNW,Sun-Fire-V490
Is any one has face similar issue? Is it related to any OS patch?
Let me know any information regarding this.
Thanks,
Paresh

The folks at NotebookCheck do the kind of benchmarks you reference. You can see their results at:
http://www.notebookcheck.net/Lenovo-ThinkPad-W550s-Workstation-Review.137989.0.html
The tests I ran were just to help me decide which laptop to use since I now have both.
I do use ATTO as well as CrystalDiskMark for disk/SSD read and write testing. Of course both go off the map when you enable RAPID in the Lenovo with the Samsung 850 Pro installed. RAPID does actually speed up work processing...not just wow the I/O test software.
I was getting about 550/450 MB/s read/write with both laptops before I enabled RAPID. With RAPID I get 3345 read and 1833 write with the Lenovo.
Too bad RAPID does not work with all Samsung SSD storage devices.

'BAPI_GOODSMVT_CREATE' takes more time for creating material document

Hi Experts,
I m using 'BAPI_GOODSMVT_CREATE' in my custom report, it takes more time for creating Material documents.
Please let me know if there is any option to overcome this issue.
Thanks in advance

Hi,
please check if some of following OSS notes are not valid for your problem:
[Note 838036 - AFS: Performance issues during GR with ref. to PO|https://service.sap.com/sap/support/notes/838036]
[Note 391142 - Performance: Goods receipt for inbound delivery|https://service.sap.com/sap/support/notes/391142]
[Note 1414418 - Goods receipt for customer returns: Various corrections|https://service.sap.com/sap/support/notes/1414418]
The other idea is not to commit each call, but executing commit of packages e.g. after 1000 BAPI calls.
But otherwise, I am afraid you can not do a lot about performance of standard BAPI. Maybe there is some customer enhancement which is taking too long inside the BAPI, but this has to be analysed by you. To analyse performance, just execute your program via tr. SE30.

'BAPI_GOODSMVT_CREATE' takes more time for creating material document for the 1st time

Hi Experts,
I am doing goods movement using BAPI_GOODSMVT_CREATE in my custom code.
Then there is some functional configuration such that, material documents and TR and TO are getting created.
Now I need to get TO and TR numbers from LTAK table passing material documnt number and year, which I got from above used BAPI.
The problem I am facing is very strange.
Only for the 1st time, I am not finding TR and TO values in LTAK table. And subsequent runs I get entries in LTAK in there is a wait time of 5 seconds after bapi call.
I have found 'BAPI_GOODSMVT_CREATE' takes more time for creating material document with similar issue, but no solution or explanation.
Note 838036 says something similar, but it seems obsolete.
Kindly share your expertise and opinions.
Thanks,
Anil

you got three large NOs .... all three recommendations are wrong!
The SE16 test is going in the right direction ... but what was filled. Nobody knows!!!!
Select options:
Did you ever try to trace the SE16? The generic statement has for every field an in-condition!
Without the information what was actually filled, nobody can say something there
are at least 2**n combinations possible!
Use ST05 for SE16 and check actual statement plus explain!

How to stop the sap crm search in the middle if it takes more time

Hi,
We are in SAP CRM 7.0 EHP1.
In webui, if we search for any customer, product, contact, transactions and the volume of results list is more, system takes more time to diplay it in results list and till that time wheel spins. If user decides to stop the search, the only option they have is logoff or F5 which will take to new session.
But I came to know in EHP1, options are there to stop the search manually and proceed with other transactions/search in the same session.If any one knows this, pl share the details.

Setting ECHO ON takes more time?

Hi all,
Recently, we had to run a huge file with INSERTs in production database. But before that when the same file was run in testing database, we set the ECHO on in SQL*PLUS and it took more time, I mean, the difference was huge, in fact. I wish to know if setting ECHO to ON takes more time than setting ECHO to OFF. Does this have an effect on time it takes to make the INSERTs.
Regards,
...

Yingkuan,
Thanks for the reply. In fact, I know the function what ECHO does. Now suppose I have 121,000 lines of INSERT statements in a file called "inserts.sql" and I am going to execute it in SQL*PLUS to a remote server, the server being 9.2.0.8.0. Will there be a time difference in completing the scripts if I set the ECHO to ON and if I set the ECHO to OFF. Consider the following scenario:
Scenario 1
========
SQL> SET ECHO ON;
SQL> @inserts.sql;
Elapsed: 02:00:00.00
Scenario 2
========
SQL> SET ECHO OFF;
SQL> @inserts.sql;
Elapsed: 01:00:00.00
Please note the "Elapsed" time between the 2 scenarios. Will the ECHO setting impact the elapsed time? I think this setting will not cause the file to take long time to complete as it is just a client side setting. Please clarify.
Regards,
...

Publishing EJBs takes more time in Oracle Weblogic 10.3 workshop

Hi,
We recently migrated from Weblogic 9.2 to Oracle Weblogic 10.3 workshop.
I have a ejb project which has more than 30 ejb's(both entity and session ejbs).
The problem is: whenever I modify the code inside a method and save, it builds the project automatically. After that when I try to publish the module, it takes around 5 - 10 minutes for publishing.
Points to note are : The ejb I am modifying has reference to other (10 - 20) ejbs. Hence it takes more time for even for single ejb change.
however, when i modify an ejb which has no reference to ejb, takes less time to publish.
My question is : is there a way to reduce the publishing time in this scenario.
Thanks in advance!

Mink,
If the calculation script ,which you are using is the same which performed better before and data being processes is same ( i mean data might not have exceptionally grown more).Then, there must be other reasons like server side OS , processor or memory issues.Consult sys admin .Atleast you ll be sure that there is nothing wrong with systems.
To fine tune the calc , i think , you can minimise fix statements . But,thats not the current issue though

Oracle coherence first read/write operation take more time

I'm currently testing with oracle coherence Java and C++ version and from both versions for writing to any local or distributed or near cache first read/write operation take more time compared to next consecutive read/write operation. Is this because of boost operations happening inside actual HashMap or serialization or memory mapped implementation. What are the techniques which we can use to improve the performance with this first read/write operation?
Currently I'm doing a single read/write operation after fetching the NamedCache Instance. Please let me know whether there's any other boosting coherence cache techniques available.

In which case, why bother using Coherence? You're not really gaining anything, are you?
What I'm trying to explain is that you're probably not going to get that "micro-second" level performance on a fully configured Coherence cluster, running across multiple machines, going via proxies for c++ clients. Coherence is designed to be a scalable, fault-tolerant, distributed caching/processing system. It's not really designed for real-time, guaranteed, nano-second/micro-second level processing. There are much better product stacks out there for that type of processing if that is your ultimate goal, IMHO.
As you say, just writing to a small, local Map (or array, List, Set, etc.) in a local JVM is always going to be very fast - literally as fast as the processor running in the machine. But that's not really the focus of a product like Coherence. It isn't trying to "out gun" what you can achieve on one machine doing simple processing; Coherence is designed for scalability rather than outright performance. Of course, the use of local caches (including Coherence's near caching or replicated caching), can get you back some of the performance you've "lost" in a distributed system, but it's all relative.
If you wander over to a few of the CUG presentations and attend a few CUG meetings, one of the first things the support guys will tell you is "benchmark on a proper cluster" and not "on a localised development machine". Why? Because the difference in scalability and performance will be huge. I'm not really trying to deter you from Coherence, but I don't think it's going to meet you requirements when fully configured in a cluster of "1 Micro seconds for 100000 data collection" on a continuous basis.
Just my two cents.
Cheers,
Steve
NB. I don't work for Oracle, so maybe they have a different opinion. :)

Af:commandNavigationItem takes more time to perform action on screen

For my project there is a dynamic implementation of af:commandNavigationItem and the actions also will be binded during runtime.
This code was working fine with the JDeveloper 11.1.1.0.2 (OWS 10.3.0) Version, but after migrating the code to JDeveloper 11.1.1.2.0 (OWS 10.3.2), it shows hourglass for a longer time (which was unusual) and then it perform the operation.
I ran the project in Debug mode and I found it takes more time to come to the breakpoint.
It writes the below information in console
<UnifiedDialogTag><setVisible> property "visible" setter is using a no-op implementation. Used in extreme cases when the property value, beyond the default value, results in unwanted behavior.
Experts: Please through some light to proceed with this issue as I am looking some lead information from where I have to look into the issue.

Hi,
can you file a bug or provide a testcase ?

MRP job takes more time (Duration / Sec)

Hello PP Guru’s,
I have below situation in production environment,
MRP job for plant – A (Takes more time – 14.650)
MRP job for plant – B (Takes less time – 4.512)
When I compare the variant / attributes with plant A and B, I observe only difference in attribute is scheduling (2 - Lead Time Scheduling and Capacity Planning) for plant A.
For plant B scheduling (1- Determination of Basic Dates for Planned) it was updated.
So in my observation this scheduling is playing a major role for MRB job which takes more time in plant – A.
I am in process of changing the variant attribute for plant – A from scheduling 2 to scheduling 1.
I wanted to know from experts whether if I change any impact / problem will happen in future for plant A or not.
Please let me know what all the hidden impacts are there if I change the scheduling in variant attribute.
I look forward to your valuable input to reduce time for my MRP related job.
Regards,
Kumar S

Hi Kumar,
You have no need to change the inhouse production time you just need to update the Lot size dependent inhouse production time in work scheduling view of material master. That you can do by scheduling the routing/recipe.
Transactions CA97 or CA97N can be used to update the in-house production time with the information from the routing.
If business don't want to have the capacity planning for planned orders then you change the scheduling from 2 to 1 basic date scheduling.
Expert Caetano already answer you query
The reports listed below can be used to compare the MRP past executions regarding the runtime:
RMMDMONI: This report compares the runtime of the MRP execution and also provides the total of planning elements (planned orders, purchase requisitions, etc) changed, created or deleted. It also shows which planning parameters where used and how much time MRP spent on each step (database read, BOM explosion, MRP calculation, scheduling, BAdIs, etc). With this information is possible to observe the relation of runtime and number of elements changed/created/deleted and also to see on which step MRP is taking more time.
RMMDPERF: This report shows the "material hit list", that means, which materials had the highest runtime during the MRP execution and also on which step MRP is taking more time. Knowing which materials have the highest runtime, allow you to isolate the problem and reproduce it on MD03, where it is possible to run an ABAP or SQL trace for a more detailed analysis.
