Performance issue when put weblogic in Windows service

I am running a performance test on our application which sits on top of bea weblogic server 7.0sp2, I found out when I run the server as windows service, performance is much worse than I run it in command prompt. any thoughts ?
btw, I am running W2K SP4 server, 4G MEM, 4 CPUSs

It's hard to tell without more information, but my first suggestion
would be to double-check that the same parameters/config are being used
in both cases.
Any idea what part of your app is taking more time?

Performance issues while accessing the Confirm/Goods Services' transaction

Hello
We are using SRM 4.0 , through Enterprise Portal 7.0.
Many of our users are crippled by Performance issues when accessing the Confirm/Goods Services tab( Transaction bbpcf02).
The system simply clocks and would never show the screen.
This problem occurs for some users all the time, and some users for some time.
It's not related to the User's machine as others are able to access it fast using the same machine.
It is also not dependent on the data size (i.e.no . of confirmations created by the user).
We would like to know why only some users are suffering more pronouncedly, and why is this transaction generally slower than all others.
Any directions for finding the Probable cause will be highly rewarded.
Thanks
Kedar

Hi Kedar,
Please go through the following OSS Notes:
Note 610805 - Performance problems in goods receipt
Note 885409 - BBPCF02: The search for confirmation and roles is slow
Note 1258830 - BBPCF02: Display/Process confirmation response time is slow
Thanks,

Performance Issues when editing large PDFs

We are using Adobe 9 and X Professional and are experiencing performance issues when attempting to edit large PDF files. (Windows 7 OS). When editing PDFs that are 200+ pages, we are seeing pregnated pauses (that feel like lockups), slow open times and slow to print issues.
Are there any tips or tricks with regard to working with these large documents that would improve performance?

You said "edit." If you are talking about actual editing, that should be done in the original and a new PDF created. Acrobat is not a very good editing tool and should only be used for minor, critical edits.
If you are talking about simply using the PDF, a lot depends on the structure of the PDF. If it is full of graphics, it will be slow. You can improve this performance by using the PDF Optimize to reduce graphic resolution and such. You may very likely have a bloated PDF that is causing the problem and optimizing the structure should help.
Be sure to work on a copy.

Performance issue when a Direct I/O option is selected

Hello Experts,
One of my customers has a performance issue when a Direct I/O option is selected. Reports that there was increase in memory usage when Direct I/O storage option is selected when compared to Buffered I/O option.
There are two applications on the server of type BSO. When using Buffered I/O, experienced a high level of Read and Write I/O's. Using Direct I/O reduces the Read and Write I/O's, but dramatically increases memory usage.
Other Information -
a) Environment Details
HSS - 9.3.1.0.45, AAS - 9.3.1.0.0.135, Essbase - 9.3.1.2.00 (64-bit)
OS: Microsoft Windows x64 (64-bit) 2003 R2
b) What is the memory usage when Buffered I/O and Direct I/O is used? How about running calculations, database restructures, and database queries? Do these processes take much time for execution?
Application 1: Buffered 700MB, Direct 5GB
Application 2: Buffered 600MB to 1.5GB, Direct 2GB
Calculation times may increase from 15 minutes to 4 hours. Same with restructure.
c) What is the current Database Data cache; Data file cache and Index cache values?
Application 1: Buffered (Index 80MB, Data 400MB), Direct (Index 120MB; Data File 4GB, Data 480MB).
Application 2: Buffered (Index 100MB, Data 300MB), Direct (Index 700MB, Data File 1.5GB, Data 300MB)
d) What is the total size of the ess0000x.pag files and ess0000x.ind files?
Application 1: Page File 20GB, Index 1.7GB.
Application 2: Page 3GB, index 700MB.
Any suggestions on how to improve the performance when Direct I/O is selected? Any performance documents relating to above scenario would be of great help.
Thanks in advance.

Sudhir

Sudhir,
Do you work at a help desk or are you a consultant? you ask such a varied range of questions I think the former. If you do work at a help desk, don't you have a next level support that could help you? If you are a consultant, I suggest getting together with another consultant that actually knows more. You might also want to close some of your questions,. You have 24 open and perhaps give points to those that helped you.

Performance issues when creating a Report / Query in Discoverer

Hi forum,
Hope you are can help, it involves a performance issues when creating a Report / Query.
I have a Discoverer Report that currently takes less than 5 seconds to run. After I add a condition to bring back Batch Status that = Posted we cancelled the query after reaching 20 minutes as this is way too long. If I remove the condition the query time goes back to less than 5 seconds.
Please see attached the SQL Inspector Plan:

Is there anything i can do in Discoverer Desktop / Administration to avoid this problem.
Many thanks,
Lance

Hi Rod,
I've tried the condition (Batch Status||'' = 'Posted') as you suggested, but the qeury time is still over 20 mins. To test i changed it to (Batch Status||'' = 'Unposted') and the query was returned within seconds again.
Ive been doing some more digging and have found the database view that is linked to the Journal Batches folder. See below.
I think the problem is with the column using DECODE. When querying the column in TOAD the value of P is returned. But in discoverer the condition is done on the value Posted. Im not too sure how DECODE works, but think this could be the causing some sort of issue with Full Table Scans. How do we get around this?

Oracle Retail 13 - Performance issues when open, save, approving worksheets

Hi Guys,
Recently we started facing performance issues when we started working with Oracle Retail 13 worksheets from within the java GUI at clients desktops.
We run Oracle Retail 13.1 powered by Oracle Database 11g R1 and AS 10g in latest release.
Issues:
- Opening, saving, approving worksheets with approx 9 thousands of items takes up to 15 minutes.
- Time for smaller worksheets is also around 10 minutes just to open a worksheet
- Also just to open multiple worksheets takes "ages" up to 10-15 minuts
Questions:
- Is it expected performance for such worksheets?
- What is your experience with Oracle Retail 13 in terms of performance while working with worksheets - how much time does it normally take to open edit save a worksheet?
- What are the average expected times for such operations?
Any feedback and hints would be much appreciated.
Cheers!!

Hi,
I guess you mean Order/Buyer worksheets?
This is not normal, should be quicker, matter of seconds to at most a minute.
Database side tuning is where I would look for clues.
And the obvious question: remember any changes to anything that may have caused the issue? Are the table and index statistics freshly gathered?
Best regards, Erik Ykema

Weblogic Server does not show managed server started when I used the Windows service to start it.

I created a windows service to start a managed server and the services was created successfully and stated. WHen I go to the Weblogic Server Admn console, the server is still showing shutdown. Whenm I try to start it, it returns with error that the the service is not able to start. Has anyone ran into anything similar. I am running on Windows Server 2008R2 and running Weblogic Server 10.3.6 and Fusion Middleware 11.1.6.

Hi,
For starting managed server as windows service there is no need of nodemanager .
Please follow the steps given in the below doc:

Hi shubhu,
I just analyzed your partial Thread Dump data, the problem is that the ajax4jsf framework ResponseWriterContentHandler triggers internally a new instance of the DocumentBuilderFactory; every time; triggering heavy IO contention because of Class loader / JAR file search operations.
Too many of these IO operations under heavy load will create excessive contention and severe performance degradation; regardless of the OS you are running your JVM on.
Please review the link below and see if this is related to your problem.. This is a known issue in JBOSS JIRA when using RichFaces / ajaxJSF.

How to get around a performance issue when dealing with a lot of data

Hello All,
This is an academic question really, I'm not sure what I'm going to do with my issue, but I have some options. I was wondering if anyone would like to throw in their two cents on what they would do.
I have a report, the users want to see all agreements and all conditions related to the updating of rebates and the affected invoices. From a technical perspective ENT6038-KONV-KONP-KONA-KNA1. THese are the tables I have to hit. The problem is that when they retroactively update rebate conditions they can hit thousands of invoices, which blossoms out to thousands of conditions...you see the problem. I simply have too much data to grab, it times out.
I've tried everything around the code. If you have a better way to get price conditions and agreement numbers off of thousands of invoices, please let me know what that is.
I have a couple of options.
1) Use shared memory to preload the data for the report. This would work, but I'm not going to know what data is needed to be loaded until report run time. They put in a date. I simply can't preload everything. I don't like this option much.
2) Write a function module to do this work. When the user clicks on the button to get this particular data, it will launch the FM in background and e-mail them the results. As you know, the background job won't time out. So far this is my favored option.
Any other ideas?
Oh...nope, BI is not an option, we don't have it. I know, I'm not happy about it. We do have a data warehouse, but the prospect of working with that group makes me whince.

My two cents - firstly totally agree with Derick that its probably a good idea to go back to the business and justify their requirement in regards to reporting and "whether any user can meaningfully process all those results in an aggregate". But having dealt with customers across industries over a long period of time, it would probably be bit fanciful to expect them to change their requirements too much as in my experience neither do they understand (too much) technology nor they want to hear about technical limitations for a system etc. They want what they want if possible yesterday!
So, about dealing with performance issues within ABAP, I'm sure you must be already using efficient programming techniques like using Hash internal tables with Unique Keys, accessing rows of the table using Field-Symbols and all that but what I was going to suggest to you is probably look at using [Extracts|http://help.sap.com/saphelp_nw04/helpdata/en/9f/db9ed135c111d1829f0000e829fbfe/content.htm]. I've had to deal with this couple of times in the past when dealing with massive amount of data and I found it to be very efficient in regards to performance. A good point to remember when using Extracts that, I quote from SAP Help, "The size of an extract dataset is, in principle, unlimited. Extracts larger than 500KB are stored in operating system files. The practical size of an extract is up to 2GB, as long as there is enough space in the filesystem."
Hope this helps,
Cheers,
Sougata.

Performance Issue in NetworkInterface.getNetworkInterface in windows JRE 7

NetworkInterface.getNetworkInterface() call takes 10 times more time when run in Windows JRE 7. The same call runs much faster in JRE 6.
Sample Program,
I wrote a small program which just fetches the network interfaces using java.net.NetworkInterface.getNetworkInterfaces() as below,
------------------------------------ Program Start ------------------------------------
import java.net.*;
import java.util.*;
public class PerfNetTest {
public static void main(String args[]) throws Exception {
     long startTime = System.currentTimeMillis();
     Enumeration niEnum = NetworkInterface.getNetworkInterfaces();
     long endTime = System.currentTimeMillis();
     System.out.println ( "Total Time Taken For One Call: " + (endTime-startTime));
     startTime = System.currentTimeMillis();
     for (int i = 0; i < 10; i++) {
          niEnum = NetworkInterface.getNetworkInterfaces();
     endTime = System.currentTimeMillis();
     System.out.println ( "Total Time Taken For Ten Call: " + (endTime-startTime));
------------------------------------ Program End ------------------------------------
Compiled the above code in Java 6 and ran the above program in JRE 6 and JRE 7. JRE 7 takes approximately 10 times more time than JRE 6. This leads to a huge performance issue in our project.
I ran it 5 times in each JRE versions and below are the test results,
When run in JRE 6
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 18
Total Time Taken For Ten Call: 81
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 17
Total Time Taken For Ten Call: 80
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 19
Total Time Taken For Ten Call: 80
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 18
Total Time Taken For Ten Call: 79
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 18
Total Time Taken For Ten Call: 80
When run in JRE 7
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 98
Total Time Taken For Ten Call: 891
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 100
Total Time Taken For Ten Call: 869
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 98
Total Time Taken For Ten Call: 859
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 99
Total Time Taken For Ten Call: 871
c:\test\net>java PerfNetTest
Total Time Taken For One Call: 99
Total Time Taken For Ten Call: 888
Is there any other way to optimize the performance in JRE 7 internally, Can the above issue considered as a bug with Windows JRE 7? Can I go and submit a bug for this?

I have simplified the program to point out the exact issue. In the actual usage we need to know immediately or whenever there is an ip change, it might be because of the change in ip to same nic card or when connected to a network via any of the nic card (wifi enabled, etc).
Overall it is particularly important to as we used to get the NetworkInterfaces for every features. As a result of this, 60 feature which gets executed roughly around .5 milliseconds in java6, now consumes almost 6-10 seconds in java 7.
Also in our client server application, where client queries for NetworkInterfaces and further sends a requests to the server where we have to support at least 100 transaction per seconds(TPS for complete client-server throughput), with 100's of client systems querying for its own NetworkInterface is consuming time and certainly reduces the overall throughput.
Currently I am more inclined to cache it and refresh in a separate thread internally, but certainly I wanted to avoid it because the throughput will be less for the first request and especially when it works perfectly fine with java6.

How to Improve performance issue when we are using BRM LDB

HI All,
I am facing a performanc eissue when i am retriving the data from BKPF and respective BSEG table....I see that for fiscal period there are around 60lakhs records. and to populate the data value from the table to final internal table its taking so much of time.
when i tried to make use of the BRM LDB with the SAP Query/Quickviewer, its the same issue.
Please suggest me how to improve the performance issue.
Thanks in advance

IOS - Performance issues when touching screen

Hello,
I am having perfomance issues when the use keep moving one finger on the screen.
I am testing with :
- flash builder 4.7 beta 2
- air 3.5 (beta too I guess)
- iPhone 3GS running on iOS 6.0.1 (also tested on an iPad3, and even though it's less horrible, the impact is still huge compared to what you could expect).
- gpu mode
- always published as an addhoc release build (best)
Test 1-A) :
- Have a completely empty project, add a fps counter (with mouseEnabled and children false).
- run a while each frame so you force the fps under 60 (if not you won't see it going down from let's say theoric 100 to theoric 70 since fps max is 60).
like this for example :
                                        protected function framingMouseTest(e : Event) : void {
                       var t : int = getTimer();
                       while (getTimer()-t<30) {}//this will keep flash busy
Notice that when you keep your finger on the screen and move it you loose approximately 7ms per frame. (for example from 26 to 22fps or from 48 to 36 fps, depending on the time waited in your while).
Test 1-B) do the same with even stage mouseEnabled false (and you could even set it + mouseChildren off recursively from stage) : same result (-7ms). Why ? Since it is all off it shouldn't take more than 1 ms no ?
Test 1-C) add Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT; Same result (found some threads saying it would help but not that much...)
Test 1-D) Multitouch.mapTouchToMouse = false;          It is a bit better but still around 5ms (didnt write down this one)
Test 1-D) Multitouch.mapTouchToMouse = false; Multitouch.inputMode = MultitouchInputMode.NONE;          It is a bit better but still around 4ms (didnt write down this one) And you have now nothing left to remove I think.
Now the horrible part :
Test 2-A)
Add some clips and subclips to your scene, containing bitmaps, results may vary depending on how much (let's say 30, I don't have the exact count on subcontainers), etc. but what's important is the difference between no finger and 1 finger moving on screen.
On normal conditions (keep some mouseEnabled for the clips you need interaction add those a listener, lets say 10 total, default values for the rest) you can get about 40ms per frame down ! (for example from 36 to 14 fps) just by touching the screen.
Test 2-B) Recursively set everything to mouseEnabled and children false after everything is added, you still get about 30ms down because of the finger, whereas it shouldn't test above the main container which already has mouseChildren false.
Test 2-C) Multitouch.mapTouchToMouse = false; Multitouch.inputMode = MultitouchInputMode.NONE; you still get about 20ms down !!! whereas you're in a mode when touch and mouseEvents shouldn't even exist.
I am really confused. My conclusions are :
Performance are really impacted whatever you do when a user touch the screen + it will get worse the more clips/depth you have. Even if everything is made to disable this.
I think anyone could test this with pretty much any app done with AIR on iOS, as long as the framerate is already <max (<60 for example), touch and move your finger and tell me what happens regarding framerate.
What I would love :
1) tell me what I am missing if you think this is due to some mistake on my part, if not :
2) better perfomance when containers have mouseChildren false. It seems obvious it still takes longer to process.
3) a mode where the touch/mouse is REALLY disabled including stage etc. It is quite obvious air does takes longer to handle touch as the scene gets more complex, even if you disable it all (seems to work only 20%...)
4) a mode where the touch/mouse is REALLY disabled, on anything but the stage. Because you might want to handle everythin just from stage coordinates, if your project allows you to, like mine. Unfortunately right now it wouldn't give you enough performance boost (well, a bit but still maybe +20ms).
PS : you don't even need to add mouselistener or touchlisteners (tested both), but if you do, it is worse.
Compared to this, I am finding rendering performance pretty decent - even though it's tough for a game on a 3GS- as long as you do it properly.

Could you open a bug report on this at bugbase.adobe.com? Please include any sample code or applications so we can quickly reproduce the problem. If you'd like to keep this private, feel free to send them to me directly ([email protected]). Also, please note in the bug if this is new behavior with the latest AIR sdk or if you've seen this in past versions too. Once added, let me know the bug number and I'll follow up internally. I've alerted the iOS team to expect this bug.
Thanks,
Chris

Weblogic as windows service

I started weblogic domain as windows service as it described in http://docs.oracle.com/cd/E21764_01/web.1111/e13708/winservice.htm#i1186180.
After that i login to administrative console and i see, that DMS application deployed state in failed. In log i see, that weblogic does not see needed classes. Also I can't deploy my enterprise application for the same reason.
If I start weblogic domain as script, than all start successfully and I can deploy any application well.
What classpath is absent in windows script?

The installSvc script calls just commEnv to set the classpath
call "%WL_HOME%\common\bin\commEnv.cmd"What you can try to do is call the setDomainEnv.cmd file instead (this also calls commEnv).
Usually with fusion middleware components extra classpath entry are added in the setDomainEnv script.
The setDomainEnv script is located in the <middleware-home>\user_projects\domains\domain-name\bin directory.

11.2.0.0 upgrade- performance issue when commits

We have upgraded our data warehouse system from 10.2.0.4 for 11.2.0.2. After upgrade ETL system has performance issue. Extraction is fine because we compared the explain plans before and after upgrade. However, loading is taking very long. In loading there is a commit after every 1000 records, that why its slow. Even when we import data with commit=y option its very slow. Is there any know issue on this?
Any help pl?
Thanks

We are solaris 10. ETL job on 10.2.0.3 was taking 2 hours and now its taking 11 hours.
I beleive commit is a issue because
1. Source query (Extraction) has same explain plan.
2. Source database is still on 10.2.0.3
3. Servers and network is same for 10g and 11g.
4. I already experienced COMMIT=y performance issue in import.
Thanks

Different thread/memory limits when running Java via Windows Service?

My company is developing a Java application that employs a "black-box" interface, which generates several memory-intensive threads. When we run the application via a batch file, the threads seem to run in parallel on a quad-core server. However, when we install the application as a Windows Service on the same server, it appears that we hit a hard limit of 35 threads, and the process pegs out one of the server's CPU's at 100%. Does anyone know why we don't see the parallelism when we run it as a Windows Service? Does anyone know if Windows imposes different memory or thread restrictions on services, as opposed to normal desktop applications?
