JDBC & orcacl performance issue..

I know this is not the right place to post this memo but some of you are very nice and have deep knowledge of what i am going to ask....
I have a java programme which call a stored procedure using oracle callable
( OracleCallableStatement ) slowConn.prepareCall( "{ call my_stored_proc(?,?) }");
which takes about less than a second..
Now, if i run this in a loop, in other words if this get calls multiple times, my cpu go crazy... almost 99% with 50 calls to this stored procedure if ran ||.
I checked about caching it. I did cached it but still my cpu consumption is same.
Any help is great. My connections are hopfully being closed or being opened as required..
Thanks in advance..

I don't have an answer, but profiling the jdbc connection in jamon may give you an idea what method is slow. It works with oracle, is free and requires no code changes.

Thanks in advance..Hello,
Are you opening and closing the connection in the for loop??
It is better to use a single connection and call the procedure multiple times.
I hopes this helps you..

Performance issues in Proxy-XI-Jdbc scenario

Hello,
I have developed a proxy to JDBC synchronous scenario.
My scenario works like this.
*i run an abap program which calls a client proxy,
the proxy fetches the data from database table and returns the data in the ABAP program.(select query)
there are serious performance issues when we are running the report
it is taking around 2-5 minutes and at times multiple users are logged in , it takes around 5-20 minutes.
it seems that most of the time is consumed in the data fetching.
please help me to find some solution so that we can fine tune the performance on the PI side.
Are there any options on JDBC CC which can help us in making the queries faster
thanks
kannu.

Kanu16 ,
Issue seems to be at r/3 end..
1. Make sur ethat report program is using select query in proper fashion .
2. avoid using nested loops.
3. Hope not much validations are being done on selected data .
Abaper can help you optimizing this .
By debugging you can find out the exact reason behind.
Regards ,

Performance Issue in 8_1_7

After upgrading from 8.1.6 to 8.1.7 both database and JDBC drivers I am facing a significant performance issues in AQ. getQueue() method takes arounf 2 minutes in 8.1.7 whereas it was taking just 19 seconds in 8.1.6. Can someone throw light on this. Thanks !!

I got in this thread by searching for getQueue() performance topic. Producing stats for aq$_queues does work, and it improves performance by 50% when there are large number of queues. I think it can be further improved by looking into other tables used by getQueue(). Could you explain how's the sql statement issued by getQueue() look like ? The reason I'm asking this is based on the obersavtion we have after applying the stats of aq$_queues: Under one instance there are two users having queues, the 1st user has 4 queues, the 2nd users 400 queues; the getQueue() of 1st user is almost twice faster than that of the 2nd user.

Oracle 9i reading BLOB performance issues

Windows XP Pro SP2
JDK 1.5.0_05
Oracle 9i
Oracle Thin Driver for JDK 1.4 v.10.2.0.1.0
DBCP v.1.2.1
Spring v1.2.7 (I am using the JDBC template for convenience)
I have run into serious performance issues reading BLOBs from Oracle using oracle's JDBC thin driver. I am not sure if it a constraint/mis-configuration with oracle or a JDBC problem.
I am hoping that someone has some experience accessing multi-MB BLOBs under heavy volume.
We are considering using Oracle 8 or 9 as a document repository. It will end up storing hundreds of thousands of PDFs that can be as large as 30 MBs. We don't have access to Oracle 10.
TESTS
I am running tests against Oracle 8 and 9 to simulate single and multi-threaded document access. Out goal is to get a sense of KBps throughput and BLOB data access contention.
DATA
There is a single test table with 100 rows. Each row has a PK id and a BLOB field. The blobs range in size from a few dozen KB to 12MB. They represent a valid sample of production data. The total data size is approx. 121 MBs.
Single Threaded Test
The test selects a single blob object at a time and then reads the contents of the blob's binary input stream in 2 KB chunks. At the end of the test, it will have accessed all 100 blobs and streamed all 121 MBs. The test harness is JUnit.
8i Results: On 8i it starts and terminates successfully on a steady and reliable basis. The throughput hovers around 4.8 MBps.
9i Results: Similar reliability to 8i. The throughput is about 30% better.
Multi-Threaded Test
The multi-threaded test uses the same "blob reader" functionality used in the single threaded test. However, it spawns 8 threads each running a separate "blob reader".
8i Results: The tests successfully complete on a reliable basis. The aggregate throughput of all 8 threads is a bit more than 4.8 MBps.
9i Results: Erratic. The tests were highly erratic on 9i. Threads would intermittently lock when accessing a BLOB's output stream. Sometimes they lock accessing data from the same row, othertimes it is distinct rows. The number and the timing of the thread "locks" is indeterminate. When the test completed successfully the aggregate throughput of the 8 threads was approx. 5.4 MBps.
I would be more than happy to post code or the data model if that would help.

Hi Murphy16,
Try investigate where are the principal issues in your RAC system.
Check:
* Expensive SQL's;
* Sorts in disks;
* Wait Events;
* Interconnect hardware issues;
* Applications doing unnecessary manual LOCKs (SQL);
* If SGA is adequatly sized (take care to not use of SWAP space "DISK");
* Backup's and unnecessary jobs running at business time (Realocate this jobs and backups to night window or a less intensive work hour at database);
* Rebuild indexes and identify tables that must be reorganized (fragmentation);
* Verify another software consuming resources on your server;
Please give us more info about your environment. The steps above are general, but you can use to guide u in basic performance issues.

XI performance issue

Hello ,
I am facing one XI performance issue. We are using PI 7.1 SP 7 on AIX 5.3 and Oracle 10.2.0.4
I have testing a simple file to file scenario, every 0.09 second, PI pull one 1kb size file from AIX file system and process, PI works fine, the item in Queue I see in SMQ2 is normally 10 - 20.
But someone has implemented their own Scenario, it ECC 6 send iDoc to PI, PI process and send to SQL Server 2000 by JDBC adapter, it also use Acknowledgment. They uses complicated mapping, normally takes up to 10 seconds. The performance is bad, items in Queue is about 1000+.
I really don't understand what is the problem.

Can i using RMI to solve performance issue

I have two database which in USA and CHINA, and a web application which located on USA, if the application connect to USA DB it is ok, i think no performance issue, but if connet to china DB, i sure that has even throgh VPN. So can i using RIM technology to solving the issue? Or using another solution. Thanks

So can i using RIM technology to solving the issue?It sounds like your problem is with Network latency.
I assume your web application connects to the database directly through JDBC and you're proposing to add a middle layer of RMI. Doing this will not reduce network latency - however if you're clever about how you serialize your resultsets, you can reduce the amount of network traffic and improve performance.
Have a look at this thread about compressing RMI data:
http://forum.java.sun.com/thread.jspa?threadID=606187&tstart=0
Note that compressing the data will add processing overhead at both ends.
Also remember to override the readObject/writeObject methods in the objects you're serializing.

30EA3- 2.*: Weird performance issues for editing objects

Hi,
I noticed weird performance issues for editing objects: when right-clicking on them in the navigator tree and selecting Edit, you get the old progress dialog "Connected to database XXX". This stays on screen a lot longer than it ever did (last sequence I edited over 30 seconds!).
Cancelling displays a "Error retrieving schemas" dialog, but then opens the Edit dialog correctly. No further side effects noticed, so I think sqldev is adding useless overhead here.
If confirmed, can this be bugged and/or fixed by production?
Thanks,
K.

Yes, I mean in context of other hangs reported. This one is a nasty performance issue, but IMO the others are real show stoppers.
Atomic steps are easy; any* Edit (object) action inside the context menu of the navigator or the Edit button of the object viewer.
I took a lot of dumps (every second or so) and came to these findings:

PrepareLogin Performance Issue

Hi Experts,
Can you please help me know what are the things I should consider
because I have performance issue
when my application is executing "preparelogin.do" it is taking about 30 minutes:
https://myserver:50001/myappb2b/user/preparelogin.do?secure=ON
I have the followng config.xml:
<action path="/preparelogin" type="com.sap.isa.user.action.PrepareLoginBaseAction">
     <forward name="success" path="/login.do"/>
     <forward name="failure" path="/logon/login.jsp"/>
     <forward name="darklogin" path="/login.do"/>
     <forward name="umelogin" path="/base/empty.jsp"/>
</action>
<action path="/login" type="com.sap.isa.user.action.LoginBaseAction">
     <forward name="success" path="/toModule.do?prefix=&page=/postLogin.do"/>
     <forward name="failure" path="/logon/login.jsp"/>
     <forward name="pwchange" path="/logon/pwchange.jsp"/>
     <forward name="failureUME" path="/base/error_ume.jsp"/>
</action>

<action path="/toModule" type="org.apache.struts.actions.SwitchAction"/>

<action path="/postLogin" forward="/b2b/postlogin.do"/>
<action path="/b2b/postlogin" type="com.sap.isa.isacore.action.b2b.PostLoginAction">
<forward name="success" path="/b2b/campaignfromMIG.do"/>
</action>
Can you please give me idea what may be the possible cause of login performance when it executes PrepareLoginBaseAction? Or are there configurations I need to look at?
My application uses LDAP authentication then goes to SAP UME authentication.
Thank you very much in advance.

Check some of my notes here:
[http://wiki.colar.net/sap_crm5_0_isa_trex_performance_settings]
In particular check the JDBC connection(this cause issue very similar to yours) and gateway connection sections, those can cause serious issues like this, this default settings use to be seriously too low, until recent releases.
A problem in production is harder to debug / trace, but if you can, do the single activity trace as somebody suggested.
Another option is to increase the logging, that will give you infos on how long each RFC / action class take and should allow you to locate what's slow.
When the logs are on, they are huge and it's hard to find the relevant data, so i have a small script here, that helps finding the interesting stuff (after turning on logging, you run the script and it will print out interesting lines found in the logs).
See: [http://wiki.colar.net/isa_action_rfc_tracer] ... you can use that script, or alternatively use tail/grep to do the same thing (if on *nix)
Note: edit the script, set the correct SID for your system and set showRFC to true.
compile it (javac) and run it (java)

Report Performance Issue - Activity

Hi gurus,
I'm developing an Activity report using Transactional database (Online real time object).
the purpose of the report is to list down all contacts related activities and activities NOT related to Contact by activity owner (user id).
In order to fullfill that requirment I've created 2 report
1) All Activities related to Contact -- Report A
pull in Acitivity ID , Activity Type, Status, Contact ID
2) All Activities not related to Contact UNION All Activities related to Contact (Base report) -- Report B
to get the list of activities not related to contact i'm using Advanced filter based on result of another request which is I think is the part that slow down the query.
<Activity ID not equal to any Activity ID in Report B>
Anyone encountered performance issue due to the advanced filter in analytic before?
any input is really appriciated
Thanks in advanced,
Fina

Fina,
Union is always the last option. If you can get all record in one report, do not use union.
since all records, which you are targeting, are in the activity subject area, it is not nessecery to combine reports. add a column with the following logic
if contact id is null (or = 'Unspecified') then owner name else contact name
Hopefully, this is helping.

Report performance Issue in BI Answers

Hi All,
We have a performance issues with reports. Report is running more than 10 mins. we took query from the session log and ran it in database, at that time it took not more than 2 mins. We have verified proper indexes on the where clause columns.
Could any once suggest to improve the performance in BI answers?
Thanks in advance,

I hope you dont have many case statements and complex calculations that you do in the Answers.
Next thing you need to monitor is how many rows of data that you are trying to retrieve from the query. If the volume is huge then it takes time to do the formatting on the Answers as you are going to dump huge volumes of data. Database(like teradata) returns initially like 1-2000 records if you hit show all records then even db is gonna fair amount of time if you are dumping many records
hope it helps
thanks

BW BCS cube(0bcs_vc10 ) Report huge performance issue

Ravi,
I already did that, it is not helping me much for the performance. Reports are taking 15 t0 20 minutes. I wanted any body in this forum have the same issue how
they resolved it.
Regards,
Chris

Interested by performance issue ? Read this ! If you can explain, you're a master Jedi !

This is the question we will try to answer...
What si the bottle neck (hardware) of Adobe Premiere Pro CS6
I used PPBM5 as a benchmark testing template.
All the data and log as been collected using performance counter
First of all, describe my computer...
Operating System
Microsoft Windows 8 Pro 64-bit
CPU
Intel Xeon E5 2687W @ 3.10GHz
Sandy Bridge-EP/EX 32nm Technology
RAM
Corsair Dominator Platinum 64.0 GB DDR3
Motherboard
EVGA Corporation Classified SR-X
Graphics
PNY Nvidia Quadro 6000
EVGA Nvidia GTX 680 // Yes, I created bench stats for both card
Hard Drives
16.0GB Romex RAMDISK (RAID)
556GB LSI MegaRAID 9260-8i SATA3 6GB/s 5 disks with Fastpath Chip Installed (RAID 0)
I have other RAID installed, but not relevant for the present post...
PSU
Cosair 1000 Watts
After many days of tests, I wanna share my results with community and comment them.
CPU Introduction
I tested my cpu and pushed it at maximum speed to understand where is the limit, can I reach this limit and I've logged precisely all result in graph (See pictures 1).
Intro : I tested my E5-XEON 2687W (8 Cores Hyperthread - 16 threads) to know if programs can use the maximum of it. I used Prime 95 to get the result. // I know this seem to be ordinary, but you will understand soon...
The result : Yes, I can get 100% of my CPU with 1 program using 20 threads in parallel. The CPU gives everything it can !
Comment : I put 3 IO (cpu, disk, ram) on the graph of my computer during the test...
(picture 1)
Disk Introduction
I tested my disk and pushed it at maximum speed to understand where is the limit and I've logged precisely all result in graph (See pictures 2).
Intro : I tested my RAID 0 556GB (LSI MegaRAID 9260-8i SATA3 6GB/s 5 disks with Fastpath Chip Installed) to know if I can reach the maximum % disk usage (0% idle Time)
The result : As you can see in picture 2, yes, I can get the max of my drive at ~ 1.2 Gb/sec read/write steady !
Comment : I put 3 IO (cpu, disk, ram) on the graph of my computer during the test to see the impact of transfering many Go of data during ~10 sec...
(picture 2)
Now, I know my limits ! It's time to enter deeper in the subject !
PPBM5 (H.264) Result
I rendered the sequence (H.264) using Adobe Media Encoder.
The result :
My CPU is not used at 100%, the turn around 50%
My Disk is totally idle !
All the process usage are idle except process of (Adobe Media Encoder)
The transfert rate seem to be a wave (up and down). Probably caused by (Encrypt time.... write.... Encrypt time.... write...) // It's ok, ~5Mb/sec during transfert rate !
CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
RAM, more than enough ! 39 Go RAM free after the test ! // Excellent
~65 thread opened by Adobe Media Encoder (Good, thread is the sign that program try to using many cores !)
GPU Load on card seem to be a wave also ! (up and down) ~40% usage of GPU during the process of encoding.
GPU Ram get 1.2Go of RAM (But with GTX 680, no problem and Quadro 6000 with 6 GB RAM, no problem !)
Comment/Question : CPU is free (50%), disks are free (99%), GPU is free (60%), RAM is free (62%), my computer is not pushed at limit during the encoding process. Why ???? Is there some time delay in the encoding process ?
Other : Quadro 6000 & GTX 680 gives the same result !
(picture 3)
PPBM5 (Disk Test) Result (RAID LSI)
I rendered the sequence (Disk Test) using Adobe Media Encoder on my RAID 0 LSI disk.
The result :
My CPU is not used at 100%
My Disk wave and wave again, but far far from the limit !
All the process usage are idle except process of (Adobe Media Encoder)
The transfert rate wave and wave again (up and down). Probably caused by (Buffering time.... write.... Buffering time.... write...) // It's ok, ~375Mb/sec peak during transfert rate ! Easy !
CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
RAM, more than enough ! 40.5 Go RAM free after the test ! // Excellent
~48 thread opened by Adobe Media Encoder (Good, thread is the sign that program try to using many cores !)
GPU Load on card = 0 (This kind of encoding is GPU irrelevant)
GPU Ram get 400Mb of RAM (No usage for encoding)
Comment/Question : CPU is free (65%), disks are free (60%), GPU is free (100%), RAM is free (63%), my computer is not pushed at limit during the encoding process. Why ???? Is there some time delay in the encoding process ?
(picture 4)
PPBM5 (Disk Test) Result (Direct in RAMDrive)
I rendered the same sequence (Disk Test) using Adobe Media Encoder directly in my RamDrive
Comment/Question : Look at the transfert rate under (picture 5). It's exactly the same speed than with my RAID 0 LSI controller. Impossible ! Look in the same picture the transfert rate I can reach with the ramdrive (> 3.0 Gb/sec steady) and I don't go under 30% of disk usage. CPU is idle (70%), Disk is idle (100%), GPU is idle (100%) and RAM is free (63%). // This kind of results let me REALLY confused. It's smell bug and big problem with hardware and IO usage in CS6 !
(picture 5)
PPBM5 (MPEG-DVD) Result
I rendered the sequence (MPEG-DVD) using Adobe Media Encoder.
The result :
My CPU is not used at 100%
My Disk is totally idle !
All the process usage are idle except process of (Adobe Media Encoder)
The transfert rate wave and wave again (up and down). Probably caused by (Encoding time.... write.... Encoding time.... write...) // It's ok, ~2Mb/sec during transfert rate ! Real Joke !
CPU Power management give 100% of clock to CPU during the encoding process (it's ok, the clock is stable during process).
RAM, more than enough ! 40 Go RAM free after the test ! // Excellent
~80 thread opened by Adobe Media Encoder (Lot of thread, but it's ok in multi-thread apps!)
GPU Load on card = 100 (This use the maximum of my GPU)
GPU Ram get 1Gb of RAM
Comment/Question : CPU is free (70%), disks are free (98%), GPU is loaded (MAX), RAM is free (63%), my computer is pushed at limit during the encoding process for GPU only. Now, for this kind of encoding, the speed limit is affected by the slower IO (Video Card GPU)
Other : Quadro 6000 is slower than GTX 680 for this kind of encoding (~20 s slower than GTX).
(picture 6)
Encoding single clip FULL HD AVCHD to H.264 Result (Premiere Pro CS6)
You can look the result in the picture.
Comment/Question : CPU is free (55%), disks are free (99%), GPU is free (90%), RAM is free (65%), my computer is not pushed at limit during the encoding process. Why ???? Adobe Premiere seem to have some bug with thread management. My hardware is idle ! I understand AVCHD can be very difficult to decode, but where is the waste ? My computer want, but the software not !
(picture 7)
Render composition using 3D Raytracer in After Effects CS6
You can look the result in the picture.
Comment : GPU seems to be the bottle neck when using After Effects. CPU is free (99%), Disks are free (98%), Memory is free (60%) and it depend of the setting and type of project.
Other : Quadro 6000 & GTX 680 gives the same result in time for rendering the composition.

Conclusion
There is nothing you can do (I thing) with CS6 to get better performance actually. GTX 680 is the best (Consumer grade card) and the Quadro 6000 is the best (Profressional card). Both of card give really similar result (I will probably return my GTX 680 since I not really get any better performance). I not used Tesla card with my Quadro, but actually, both, Premiere Pro & After Effects doesn't use multi GPU. I tried to used both card together (GTX & Quadro), but After Effects gives priority to the slower card (In this case, the GTX 680)
Premiere Pro, I'm speechless ! Premiere Pro is not able to get max performance of my computer. Not just 10% or 20%, but average 60%. I'm a programmor, multi-threadling apps are difficult to manage and I can understand Adobe's programmor. But actually, if anybody have comment about this post, tricks or any kind of solution, you can comment this post. It's seem to be a bug...
Thank you.

Patrick,
I can't explain everything, but let me give you some background as I understand it.
The first issue is that CS6 has a far less efficient internal buffering or caching system than CS5/5.5. That is why the MPEG encoding in CS6 is roughly 2-3 times slower than the same test with CS5. There is some 'under-the-hood' processing going on that causes this significant performance loss.
The second issue is that AME does not handle regular memory and inter-process memory very well. I have described this here: Latest News
As to your test results, there are some other noteworthy things to mention. 3D Ray tracing in AE is not very good in using all CUDA cores. In fact it is lousy, it only uses very few cores and the threading is pretty bad and does not use the video card's capabilities effectively. Whether that is a driver issue with nVidia or an Adobe issue, I don't know, but whichever way you turn it, the end result is disappointing.
The overhead AME carries in our tests is something we are looking into and the next test will only use direct export and no longer the AME queue, to avoid some of the problems you saw. That entails other problems for us, since we lose the capability to check encoding logs, but a solution is in the works.
You see very low GPU usage during the H.264 test, since there are only very few accelerated parts in the timeline, in contrast to the MPEG2-DVD test, where there is rescaling going on and that is CUDA accelerated. The disk I/O test suffers from the problems mentioned above and is the reason that my own Disk I/O results are only 33 seconds with the current test, but when I extend the duration of that timeline to 3 hours, the direct export method gives me 22 seconds, although the amount of data to be written, 37,092 MB has increased threefold. An effective write speed of 1,686 MB/s.
There are a number of performance issues with CS6 that Adobe is aware of, but whether they can be solved and in what time, I haven't the faintest idea.

Performance Issue for BI system

Hello,
We are facing performance issues for BI System. Its a preproductive system and its performance is degrading badly everyday. I was checking system came to know program buffer hit ratio is increaasing everyday due to high Swaps. So asked to change the parameter abap/buffersize which was 300Mb to 500Mb. But still no major improvement is found in the system.
There is 16GB Ram available and Server is HP-UX and with Netweaver2004s with Oracle 10.2.0.4.0 installed in it.
The Main problem is while running a report or creating a query is taking way too long time.
Kindly help me.

Hello SIva,
Thanks for your reply but i have checked ST02 and ST03 and also SM50 and its normal
we are having 9 dialog processes, 3 Background , 2 Update and 1 spool.
No one is using the system currently but in ST02 i can see the swaps are in red.
