Severe performance issues in production database
Hi Experts,
we have configured RMAN in our production database recently using some 3 party tool COMMVAULT.
Problem is just 47 GB database taking around 6 hrs of time to complted the bakcup job. Please let me know what could be the reason.
Further to this issues i found out some of few things, our application vendor commissioned this database server and it seems that they done some changes in TIMEZONE settings.
when i query against some of few dictionary tables for example dba_schedular_jobs i am getting the following error.
ORA-01882: timezone region %s not found
when ever i connect the database , the connection itself is very slow and suffering severe performance issues in my production database.
You help would be much appreciated.
Regards,
Salai
Hi,
also let us know if you use asm or local file system for datafiles.
Your backup strategy will also be helpful:
Do you make compressed backups?
Full or incremental?
To where do you backup the database? To the local filesystem, SAN Volume, Offsite Storage, Tape storage?
Is there any other jobs running while the RMAN job is running?
Please post the stats that you have gathered over the time period when the backup is running.
Thanks.

Oracle Apps Database severe Performance Issue
Hi Gurus,
This is regarding a severe performance issue running in our Production E-Business Suite Instance.
its an R12.1.3 setup installed with 11.2.0.1 Database. All the servers are Solaris Sparc 64 (Solaris 10)
Let me brief you about the instance first:
2 Node Application
- Main Application Server hosting web/forms/concurrent/admin servers
- iSupplier server hosting web services (placed in DMZ, used by external suppliers via Internet)
1 Node Database Server
Database Server Specs
Memory: 144G phys mem 20G total swap
- CPUs (8Px4cores, 2Px2cores)
- I/O - fiber channel hard disk (hitachi SAN Storage) - 7 DATA_TOPs (7 drives with RAID 5) - current DB size 1.6 TB
- at peak load, around 1000 concurrent forms session and 2000 web sessions.
We have been facing some serious performance issues and we raised an SR with Oracle Support.
The Support analyzed a bunch of AWR Reports we provided them and they asked us to increase the DB_CACHE from its current usage of 27G to 40G
So, we changed SGA_TARGET from 35G to 50G and PGA was increased from 35G to 40G as v$pgastat was also suggesting some lack of memory.
We made these changes last night.
Today morning we observed the following:
1. after start of office hours, we checked in the home page of EM DB Console that ADDM was showing reduced impact due to lack of SGA memory which seemed to be a good sign. Earlier it was around 25% which was now at 12%.
However, negative aspects were:
1. lot of swapping was reported by the System Administrators on the DB Server
2. High CPU Usage
3. EM DB Console showed a lot of "Concurrency Wait Class" events ...throughout the day lot of blocking sessions were reported which were making other sessions to wait.
in the AWR Report, following foreground reports were listed:

This is showing "library cache lock" events as the main culprit apart from the usual suspect, the CPU.
I am attaching the AWR Report. Please let me know if i should revert back the memory changes or is there anything else i could do.
Please help us resolving it because the performance is going worst.

Performance Issue Tracking In Database Level.
Hi All,
I am sorry, actually i dont know whether this is the right question to ask in this forum. Below is my question.
We are working on Oracle 10g and are supposed to moved to 11G. My question is which text book will be best one for getting knowledge regarding database performance issue in broad level and monitoring and resolving the issues. Please suggest.
Edited by: 930254 on Aug 22, 2012 7:56 AMTroubleshooting oracle performance ( Apres) is one book I found very useful along with the Oracle documentation (http://www.oracle.com/pls/db112/to_toc?pathname=server.112/e10822/toc.htm).
btw, please mark the thread as 'answered', if you feel you got your question answered. This will save the time of others who search for open questions to answer.

ERP Sales Order : Performance issues with Product Proposal
Hi
we are working on CRM 2007 solution and are facing serious performance issues with the ERP Sales Order functionality provided in the ICWC of this version.
In our development we are adding items in the ERP cart as soon as the user clicks on the 'New Sales Order' button of the sales order sreen. We get the items by very simple and optimized call to the ERP system and then add these entities in the Item Cart (Item collection ...in simple sense).
For adding 10 items the application takes 10 seconds and this is too much for adding just 10 items.
Can you please provide any Notes/alternative solution to resolve this issue.
Regards

Performance issue after upgrading database 9i (9.2.0.5.0) to 10g (10.2.5.0)
Hi,
recently we have upraded our database from 9.2.0.5.0 to 10.2.5.0. After the upgrading of the database some of our SQL-statements, who gather data and fill it in an empty tabless,
shows a really bad performance in the new database version. We already have checked the explain plan it remains the same in both versions (full table scans on the corresponding tables)
E.g. a query running in the 9i database needs 17 minutes for completion in the 10g version it needs 15 hours.
We have checked the running session and have seen that the read of database blocks of the corresponding tables needs immense more time in the 10g version.
Are there any oracle parameter, hidden features we can adjust in 10g in order to get the same performance as in 9i?
thanks in advance

Performance Issues on Oracle Database Lite 10.3.0.3
Hello,
we have a big problem with one of our customers. He uses Oracle Database Lite in the standalone version. There are about 600 clients running a project with about 20 Publication Items. The customer works in the logistics field, so the Main time where nearly all clients want to sync and get their tours is from 02 AM to 05 AM, so that is the time with the most traffic.
Everything went well before last week. Suddenly the compose cycle needs (at least between that hours) about ten times longer than before. Normally we had about 40 - 80 seconds, now we have about 300 - 500 average with max values from over 1200 seconds.
Therefore we have a lot of conflicts and Disconnects on the clients. It is sometimes that bad, that nearly no client can sync successfully.
We checked our Selects in the publication Items, all are very fast and look good in the explain plan, so that shouldnt be the problem.
The installation is nearly in the Default state as oracle does when you install Oracle Lite. Are there any standard settings we can change? Does anyone had the same problem already?
The Machine is a Windows Server 2003 with an Intel Xeon CPU E7-4820 and 4 GB of RAM.
Of course our customer gets a lot of trouble because of that and we have to improve and fix that as fast as we can.
Any recommendation or opinions are very welcome.
If I have to give more Info about somewhat please feel free to ask, I will give it as fast as possible.
Thanks in advance
HolgerHey,
many thanks for your proposals. The MGP runs every minute like the default settings are, because our application is a time sensitive. The data have to be very fast on the clients in the nights and thex are only a few minutes before available. I think the parameters are important in environemnts where the mgps runs only after a few minutes?
Let me summarize the situation since my las post:
We have days (nights) where everything goes quite well. Mainly that is thrusday and friday. But on the other hand, there are days where everything really is a mess.
The mgp caycles increase and when you look to mobile manager you see 70 clients syncing very very slowly (about 300 - 600 seconds) for just a little bit of data. Then we get the disonnects and the messages in the err.log.
What do you think, is this somehow network related, or ist this a logical problem in the Mobile Server itself?
Like postes earlier, there are 500 clients syncing against a standalone mobile server.
We just couldnt figure out, why the mgp times somehow and sometimes increase that much, that there are these problems.
First we thought, that they sync newly over wireless (GPRS or Edge) and that syncing is that slowly, that everything goes down, but arent sure. Is this possible because of the architecture of the Mobile Server? That a very slow network can slow down the mgps and that does timeouts and all the other stuff?
How many clients can a Standalone Mobile Server normally serve at same time without performance problems. What do you thin about the hardware I wrote? Is it powerful enough? -
BOE Publications performance issue in source database.
Hello all,
I have a set of BO Publications, that run nightly. The source documents are Crystal Reports that runs on Sybase stored procedures. On days when the publication runs for over 20 dynamic recepients, the tempdb in Sybase, set at 1.5GB is filling to over the threshold value and is creating warnings in the database logs. When large datasets are processed by the Crystal Reports, the tempdb tablespace fills up and the publications are failing. This tempdb issue does not occur if the Crystal Reports are run in stand-alone mode.
We monitored the Sybase system while the publications are running, and we can see that separate process ids are created in Sybase for each dynamic recepient, one after another, indicating that report instances are not run in parallel for all dynamic recepient.
Could someone with a better understanding of the BOBJ publications, post comments to help me understand how BOBJ schedules the Crystal Reports ( in parallel or series ) and why the tempdb tables in the database are filled up?
The publications are all set to 'One database fetch per recipient' in the Advanced tab, to prevent the tempdb table from filling too quickly and failing the reports.
RaviCan you run the same query on Physical SQL Server DB and let us know the outcome ?
Thanks, -
Multiple severe performance issues under Windows
I own a Macbook Pro, and have used it happily for around a year. However, the hard drive was too small (no idea why I decided to go for the 80), and my music library kept growing. At the same time, I needed a Windows machine for various other purposes, so I bought a Dell with Vista. I successfully transferred all of my music over to it, and downloaded iTunes. It installed fine, and all of my music showed up, and plays.
Here are the problems. Compared to OS X, iTunes on Windows *****. Unbelievably. It's incredibly sluggish (even basic things like scrolling through your library - smooth as silk on the Mac, but choppy on Windows. Resizing the window doesn't work well, either), and it has to have at least a few major memory leaks.
I'll give you some specifics.
Acting "Sluggish"
- Scrolling through my library (with either the scroll wheel of the mouse or the scrollbar on the right) is very choppy. This is not the case with any other application on my computer - scrolling through a list of entries is smooth and works well.
- Resizing the window frequently doesn't work. I'll grab the corner, and move the mouse over to another area. The mouse will be on a different part of the screen, but the iTunes window will not have resized at all. If I move the mouse, the window then resizes to where the mouse last was. In other words, if I want to resize the window, I have to grab the corner, drag to another size that I think I want, and then move the mouse a little to get it to go. This animation is also very choppy.
- Coverflow is very slow and moves at a very low framerate, fullscreen or otherwise.
- Oftentimes, the first keystroke (or two) will be completely ignored. So, for example, I'll hit Ctrl+L to get to the currently playing song, and have to press it 2 or 3 times in order for it to have any effect.
Memory Issues
- When I start iTunes (in the smallest window possible), it takes around 56 MB of memory, not playing anything. Once I start to play a song, it jumps a little, but ultimately doesn't change that much (now it's at 60 MB instead). I resized the window to be on most of the screen, and it's now at 66. Scrolling through my library on List View, while slow and choppy, doesn't take up any significant amount of memory. However, as soon as I change to either the "grouped with artwork" option or coverflow, bad things start happening.
- Grouped with Artwork: At the beginning, iTunes is taking up 70 MB of memory. Every time I hit Page Down, another 3-4 MB of memory is added. This memory is never released. So now, having scrolled down from the top a little, iTunes is now sitting at twice what it was at the beginning, or 145 MB. It's now taking up more memory than Firefox.
- Coverflow: Starting out at 145 MB from the earlier view, switching to coverflow immediately makes the memory jump to 170 MB. When I scroll through the albums, the memory then jumps anywhere from 40 - 50 MB. After a bit of clicking, iTunes is now taking up 1,106 MB of memory.
I minimize iTunes, and 1 MB of memory is freed. iTunes is now at 1,105 MB.
Moving out of CoverFlow view does a good job at cutting some memory use, but it's still at 540 MB. And at this point, I'm back to where I started (in terms of what iTune's doing: list mode, small window, not playing), only at 9 times the memory use. As far as I know, there's no way to reclaim that memory.
Various Issues
- iTunes will frequently disregard the first or even second keystroke, as mentioned above.
- This scenario is a little harder to describe, but I'll do my best. iTunes is the foremost application. The focus is on song panel (the main part), so that pressing the Up and Down arrow keys cause the "currently selected" blue background thing behind a song to move up or down, enter plays the currently selected song, etc. I Alt-Tab to another application, and then Alt-Tab back. It looks like I'm in the same situation as before (the currently selected song is blue, instead of grey), but the up and down keystrokes do nothing. I'm apparently in a different section of iTunes. Pressing Tab brings me to the left panel of iTunes - the Music / Movies / Podcasts / Ringtones / etc. part, but the up and down keys don't do anything there either. Tabbing again takes me to the search field, and that works. And tabbing once more brings me back to where I should have been as soon as I Alt-Tabbed back to iTunes.
- A variant situation: focus is as described at the beginning, and I Alt-Tab out and back into iTunes. Again, the up and down keys don't work, but then if I press Shift + Tab (to go to the previous field), it starts working again.
This issue is much more of a pain than it sounds. If I'm in iTunes, and I'm chatting online, for example, I might need to switch out quickly to type a line in, and then switch back, but the workflow has been completely disrupted because I can't navigate with the keyboard anymore.
- When editing a song title in iTunes, I select it first, and then press F2. This causes the title to become a "rename" field, which works mostly fine. With one exception. Generally, in these fields, you edit the title to your heart's desire, and then press Enter to signify that you are done. However, in iTunes, if I have a song title "blowin' in the wind", and I want to capitalize it, I'll hit F2, and then move the cursor over to the beginning of the title (in other words, to right before the "b"). My goal is to delete the lowercase b, and replace it with an uppercase B. So I press Delete, and then type B. However, as soon as I press the Delete key, iTunes deletes the character, and then closes the rename field. It's as though I pressed Delete and then Enter. If I then type B, I'm taken the first song starting with a B, which is not what I want at all.
- iTunes doesn't work with Vista's window preview (Aero interface, Alt+Tab or hovering over the program in the tray at the bottom) when it's minimized.
- When I have iTunes on in the background, and plug in an iPod, it all works fine, except for when I bring the window up. For whatever reason, iTunes doesn't repaint the window right at all. It's a horrific mixture of whatever songs were in the list view before and the iPod options.
I'm sure I have more issues, but those are the ones that come to the top of my head. Note that I have none of these problems in iTunes on the Mac.

Windows is the lowest performing host for GroupWise, so that is a part
of what you are hitting.
How are you monitoring memory usage? I've found that the vCenter tools
aren't a good indicator of that, where as the Windows tools are better
in that respect. The biggy is that you don't want much paging to disk.
How much do you have assigned to this VM?, how many cores? And are
these ESX box(es) over committed on those two?
Those settings on their own don't really mean a whole lot. What we need
to see is what is actually being used, and if you are running out of
them, then upping those specific numbers can help. The best way is to
watch the POA web interface for the relevant settings.

Generic Extractor on cdpos & CDHDR - severe performance issues in productio
Hello friends,
Can you take a look at my code? I have used a view in cdhdr table for extractor.code executes okay in dev and QA, but had to cancel job after running 48 hours. Any help is appreciated. This is my code in CMOD...

ENDIF.
REFRESH itab_cdpos.
CLEAR: itab_cdpos, itab_pct_data.
ENDLOOP.Pabloj,
Thanks for the attachment... I did look into this, but not able to write FM properly.
Can you correct my FM?

Performance issue showing read by other session Event
Hi All,
we are having a severe performance issue in my database when we are running batch jobs.
This was a new database(11.2.0.2) and we are testing the performance by running some batch jobs. These batch jobs included some inserts and updates.
I am seeing read by other session in top 5 timed events and cache buffers chains in Latch Miss Sources section.
Please help me to solve this out.

Performance issues with Homesharing?
I have a Time Capsule as the base station for my wireless network, then 2 Airport Express setup to extend the network around the house, an iMac i7 as the main iTunes Library and couple of iPads, and a couple of Apple TVs. Everything has the latest software, but I have several performance issues with Home sharing. I've done several tests making sure nothing is taking additional bandwidth, so here are the list of issues:
1) With nothing else running, trying playing a movie via home sharing in an iPad 2 which is located on my iMac, it stops and I have to keep pressing the play button over and over again. I typically see that the iPad tries to download part of the movie first and then starts playing so that it deals with the bandwidth, but in many cases it doesn't.
2) When trying to play any iTunes content (movies, music, photos, etc) from my Apple TV I can see my computer library, but when I go in on any of the menus, it says there's no content. I have to reboot the Apple TV and then problem fixed. I's just annoying that I have to reboot.
3) When watching a Netflix movie on my iPad and with Airplay I send the sound to some speakers via Airplay through an Airport Express. At time I lose the connection to the speakers.
I've complained about Wifi's instability, but here I tried to keep everything with Apples products to avoid any compatibility issues and stay within N wireless technology, which I understood it was much more stable.
Has anyone some suggestions?Hi,
you should analyze the db after you have loaded the tables.
Do you use sequences to generate PKs? Do you have a lot of indexex and/or triggers on the tables?
If yes:
make sure your sequence caches (alter sequence s cache 10000)
Drop all unneeded indexes while loading and disable trigger if possible.
How big is your Redo Log Buffer? When loading a large amount of data it may be an option to enlarge this buffer.
Do you have more then one DBWR Process? Writing parallel can speed up things when a checkpoint is needed.
Is it possible using a direct load? Or do you already direct load?

Hi,
Has anyone had any issues with performance when updating the planning buffer using the Exit FM? What are the things to prepare for about performance issues in production system? Please recommend.
Thanks
RTHi Rob
In the case of performances problems you should check the statistics in BPS_STAT0 for possible long database selection on data
About this topic you can try to implement the SAP note 729362
