Performance Problems after Database Upgrade to 10.1.0.5

Has anyone else encountered Discoverer Query performance suffering drastically once upgraded their database from 10.1.0.4 to 10.1.0.5? It is almost 5 times as slow.

ask your DBA to analyze the schema (gather statistics) for the concerned schema. This should eliminate one possibility

Perfomance Issue after Database Upgrade in 11i

Hi All,
We upgraded database from 9.2.0.5 to 10.2.0.4, the system was running fine. One month after upgrade we changed the compatibility from 9.2.0 to 10.2.0 for compatibilty and optimizers. Since then perfomance is poor for self service and PTO carry over is taking more then 10 hours, earlier which completes in 1:15 min to 1:30 min. I logged a SR and following with Oracle Support.
Are there any _"Best Practices"_ to be followed after database upgrade from 9i to 10g in 11.5.10.2.
All the database parameters has been set as recommeded by metalink note:216205.1

Thnaks in Advance for help.

Are there any _"Best Practices"_ to be followed after database upgrade from 9i to 10g in 11.5.10.2.
All the database parameters has been set as recommended by metalink note:216205.1
The best practice is to adjust initialization parameters as per the note referenced above.
In addition, review the following note carefully:

DataSource problems after BW upgrade

DataSource problems after BW upgrade
Upgrade from
SAP NetWeaver 2004s: SAP_BW 700 0012 SAPKW70012
to
SAP EHP 1 for SAP NetWeaver 7.0: SAP_BW 701 0007 SAPKW70107
BW system: PI_BASIS 7.01 SP 6
ECC/source system: PI_BASIS 2005_1_700 SP 11
Problem exists throughout, both with generic and standard DataSources.
Here is one specific example:
Generic DataSource ZXXXXXXXX
InfoPackage "ZXXXXXXXX(ZXXXXXXXX)" does not run. Error:
DataSource ZXXXXXXXX(SOURCESYS) must be activated
Message no. RSDS179
Then followed these steps:
1. Replicate Metadata from source system
2. Report RSDS_DATASOURCE_ACTIVATE_ALL from SE38 for source system SOURCESYS and DataSource ZXXXXXXXX
Errors returned:
Inconsistent user object ZXXXXXXXX SOURCESYS for PSA /BIC/B000XXXX
Error saving DataSource ZXXXXXXXX SOURCESYS
DataSource ZXXXXXXXX (SOURCESYS) could not be activated
When I try to choose "Manage" from the context menu for the DataSource, I see an error:
Invalid DataStore object name /BIC/B000XXXX: Reason: No valid entry in table RSTS
Message no. RSM1294
The following notes have not helped:

https://service.sap.com/sap/support/notes/1056060
And no other SDN threads seem to give fruitful suggestions.
Any ideas?

Hi,
Just to help the folks out here.
In my case,
Inspite of going through several valid NOTES & program, my issue didnt resolve (you reply was pretty accurate - but dint help me :-)).
I have resolved the issue by adjusting the PSA table for the same.
Procedure:
Take the psa name --> go to table rstsods --> find the ODSNAME_TECH name for the relevant psa --> se38 t.code --> enter ODSNAME_TECH and click on 'adjust & activate database table' (make sure you have selected 'save data' radio button.
Just in case anyone who come across this problem, can do the above steps.

Interactive report performance problem over database link - Oracle Gateway

Hello all;
This is regarding a thread Interactive report performance problem over database link that was posted by Samo.
The issue that I am facing is when I use Oracle function like (apex_item.check_box) the query slow down by 45 seconds.
query like this: (due to sensitivity issue, I can not disclose real table name)
SELECT apex_item.checkbox(1,b.col3)
, a.col1
, a.col2
FROM table_one a
, table_two b
WHERE a.col3 = 12345
AND a.col4 = 100
AND b.col5 = a.col5
table_one and table_two are remote tables (non-oracle) which are connected using Oracle Gateway.
Now if I run above queries without apex_item.checkbox function the query return or response is less than a second but if I have apex_item.checkbox then the query run more than 30 seconds. I have resolved the issues by creating a collection but it’s not a good practice.
I would like to get ideas from people how to resolve or speed-up the query?
Any idea how to use sub-factoring for the above scenario? Or others method (creating view or materialized view are not an option).
Thank you.
Shaun S.

Hi Shaun
Okay, I have a million questions (could you tell me if both tables are from the same remote source, it looks like they're possibly not?), but let's just try some things first.
By now you should understand the idea of what I termed 'sub-factoring' in a previous post. This is to do with using the WITH blah AS (SELECT... syntax. Now in most circumstances this 'materialises' the results of the inner select statement. This means that we 'get' the results then do something with them afterwards. It's a handy trick when dealing with remote sites as sometimes you want the remote database to do the work. The reason that I ask you to use the MATERIALIZE hint for testing is just to force this, in 99.99% of cases this can be removed later. Using the WITH statement is also handled differently to inline view like SELECT * FROM (SELECT... but the same result can be mimicked with a NO_MERGE hint.
Looking at your case I would be interested to see what the explain plan and results would be for something like the following two statements (sorry - you're going have to check them, it's late!)
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two),
sourceqry AS
(SELECT b.col3 x
       , a.col1 y
       , a.col2 z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5)
SELECT apex_item.checkbox(1,x), y , z
FROM sourceqry
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two)
SELECT apex_item.checkbox(1,x), y , z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5If the remote tables are at the same site, then you should have the same results. If they aren't you should get the same results but different to the original query.
We aren't being told the real cardinality of the inners select here so the explain plan is distorted (this is normal for queries on remote and especially non-oracle sites). This hinders tuning normally but I don't think this is your problem at all. How many distinct values do you normally get of the column aliased 'x' and how many rows are normally returned in total? Also how are you testing response times, in APEX, SQL Developer, Toad SQLplus etc?
Sorry for all the questions but it helps to answer the question, if I can.
Cheers

Performance Issues after an Upgrade

Hello!
We are experiencing performance issues after we upgraded to a new version of Hyperion (11.1.2.1). At this point, I am not too sure about the actual causes for this degrade in performance but I am trying to narrow down the causes and need your inputs. Please help me with your ideas.
1) What could be the causes/factors for the performance to degrade after an upgrade?
2) Does the performance of a script depend on the user credentials i.e. who is launching the script? Whether it’s the super admin of the application/application owner or an application specific admin?
3) Does the performance of the scripts depend on the place you are launching it from? For example - will the performance differ if it’s launched from MaxL Vs EAS?
Please let me know your thoughts on this.
Thanks,
- Krrish

There are a number of bugs 12600557, 12675485, 12669814, 12698488 logged in for 11.1.2.1 - If you use Internet Explorer 8 and have data forms designed to use a large number of sparse dimension members in rows or columns, you may experience performance degradation when opening the data forms.
This has been fixed in Oracle Hyperion Planning, Fusion Edition Release 11.1.2.1 Patch Set Update (PSU): 11.1.2.1.101 which is available on My Oracle Support as Patch 12666861.

I installed iOS 5.0.1 on my Iphone 3GS. I never can not write in my calendar. Anyone else having this problem after their upgrade?

I was going to suggest - Settings>General>Reset>Reset all settings, but if you are restoring to factory settings, that should restore the settings back to factory defaults. But if you are restoring from a backup, after restoring to factory settings, try resetting all of the settings and see if that fixes it.
It might be something in your backup.

i have a mac, would like to upgrade to mountain lion from mac os x, anybody experienced any problems after this upgrade, thanks

Check that your computer is compatible with Mountain Lion.
To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
iMac (Mid 2007 or newer) model number 7,1 or higher
MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
MacBook Air (Late 2008 or newer) model number 2,1 or higher
Mac mini (Early 2009 or newer) model number 3,1 or higher
Mac Pro (Early 2008 or newer) model number 3,1 or higher
Xserve (Early 2009) model number 3,1 or higher
Your Mac needs:
OS X v10.6.8 or OS X Lion already installed
2 GB or more of memory (More is better - 4 GB minimum seems to be the consensus)
8 GB or more of available space
If you can/do upgrade, I recommend you make a copy of the installer and move it out of your Applications folder. The installer self-destructs. The copy will keep you from having to download the installer again. You can make a bootable DVD/USB stick to install using this free program.
Bootable Drive DVD or USB Flash Drive – Lion Diskmaker
Our 2 computers haven't experienced any significant problems, even though others have. I find it much better than 10.7 Lion, which I used for a week before reverting to 10.6.8
Mavericks is supposed to be released this fall, so you may want to wait.

Performance Problem After upgrade to oracle 10g

Hi
I have upgrade one of my datawarehouse database from oracle 9.2.0.8 to oracle 10.2.0.4 running on solaris 9
After the upgrade jobs which were running in the database is taking hell lot of time.
The jobs are accessing the views which is used to get the monthly report data from the database.
what could be the solution and where to start from to get the RCA to resolve this performance issue
Please let me know if you require any other information
database is currently running in the automatic shared memory management mode ie SGA_MAX and SGA_TARGET parameters are defined for that

There are a lot of differences between 10g and 9i in this regard, among these are:
- There is a default job that gathers statistics every night which is not there in 9i. You might have totally different statistics as in 9i due to that job, depending on how and if at all you used to collect statistics in 9i
- The 10g DBMS_STATS package collects histograms on some columns by default (parameter METHOD_OPT=>'FOR ALL COLUMNS SIZE AUTO' default in 10g whereas 'FOR ALL COLUMNS SIZE 1' in 9i) which can have a significant effect on the execution plans
- The 10g optimizer has CPU costing enabled by default which can make significant changes to your execution plans due to different costing of table scans and order of predicate evaluation. In addition it uses NOWORKLOAD system statistics if system statistics have not been gathered explicitly
- 10g checks the min and max values stored for columns in the data dictionary. If your predicates are way off compared to these values then 10g begins to adjust the calculated selectivity of the predicate which can again significantly affect your execution plans
- 10g introduces the "Cost Based Query Transformation (CBQT)" feature which means that rather than applying heuristic transformation rules transformations are costed and potentially discarded whereas 9i applies transformations unconditionally whenever possible

Performance problem after upgrade from Web version to Basic version

A couple days I ago I 'upgraded' my SQL Azure database from the Web service tier to Basic. Since doing that the performance on many of my queries as dropped noticeably. I've made no schema changes, and the amount of data in my database has changed very
little since the upgrade. Has anyone had this same problem?
Randy Minder

Randy,
See this blog about how to upgrade to the new tiers and some advice on finding the right fit.
http://azure.microsoft.com/en-us/documentation/articles/sql-database-upgrade-new-service-tiers/
Basic is not equivalent to Web in the new Editions tiers. While you do 'upgrade' to editions, granting you access to new features and the tiers themselves, you can now choose an experience which has less performance than you had previous in Web/Business.
Try upgrading your server to a new tier based on the advice in the article above. If you read the article below:
https://msdn.microsoft.com/en-us/library/azure/dn369873.aspx
You can see that standard is actually targeting at many of the production use cases of Web, where Basic is targeting developers who were using Web, before, to test out their applications. Basic isn't intended for scenarios with multiple concurrent users.
Hopefully that helped. If you have any other questions, feel free to reply.

Chris

3D performance problems after upgrading memory

I recently purchased an additional 2GB of memory to try and extend the life of my aging computer. I installed the memory yesterday and Windows seems to recognize it (reporting now 3.3GB) but when I dropped into WoW (pretty much the only game I have) the 3D performance was down from the usual 60FPS @ 1600x1080 to a bleak 20 (at best) and the CPU utilization went to about 80% on both cores (with ~20% kernel usages). Basically WoW was being software 3D rendered!!!
I went through the usual reinstall drivers, reboot, etc... and couldn't find a fix. I powered down, pulled out 2 of the memory sticks, booted up, and dropped into WoW - it ran at the full 60FPS and CPU utilization was very low (i.e. back to GPU Hardware 3D rendering). I powered down again, swapped the 2 sticks for the other 2 sticks, booted up, and dropped into WoW - again it ran 100% fine. So I powered down, put all four sticks in, booted back up, and when I dropped into WoW it was running in the software 3D rendering mode (20FPS at best and High CPU/Kernel usage).
I've tried the /PAE option in boot.ini - no joy. I've tried /MAXMEM = to 3300, 3072, 3000, and even 2048 - no joy in any of those cases. Has anyone seen anything like this before? Or have suggestions to fix (other than going to Win7-64)?
All info in signature is up to date.
Thanks in advance for any help!

PAE or Physical Memory Extension will not do anything as Microsoft has castrated this feature to such an extend that it has nothing to do with memory addressing anymore when in comes to Windows XP:
http://en.wikipedia.org/wiki/Physical_Address_Extension#Microsoft_Windows
Quote
Windows XP Service Pack 2 and later, by default, on processors with the no-execute (NX) or execute-disable (XD) feature, runs in PAE mode in order to allow NX. The NX (or XD) bit resides in bit 63 of the page table entry and, without PAE, page table entries only have 32 bits; therefore PAE mode is required if the NX feature is to be exploited. However, desktop versions of Windows (Windows XP, Windows Vista) limit physical address space to 4 GiB for driver compatibility reasons.
The feature is already automatically enabled. But since is original function (Address Extension) does no longer exist when it comes to the desktop versions of Windows XP, it won't really do anything you would ever notice.
About the /MAXMEM Switch: In Windows 32bit operating systems, every process is limited to 2GB of memory. The point of the switch is to allow certain applications (or their run-time process) to occupy a higher amount of system memory than 2GB. However, the culprit here is that only those applications are able to utilize this ability that have been programmed (or compiled) accordingly. A special flag (large memory aware) has to be implemented. Otherwise, these application will be restricted to 2GB even though the /MAXMEM Switch has been set to extend the 2GB limit to 3GB. Most 32bit applications come without the "large memory aware" flag and that is why usually, settings the switch won't change anything.
In any case, it is unlikely that /PAE (even if it would not be castrated) and /MAXMEM would have an impact on your actual issue because I doubt that it has much to do with either memory adressing or the memory limit of an indiviual Windows process.

the 3D performance was down from the usual 60FPS @ 1600x1080 to a bleak 20 (at best) and the CPU utilization went to about 80% on both cores (with ~20% kernel usages).
There are a couple of hardware based explanations to consider here. Let's start with the most obvious one:
1. 975X Memory Controller
The main reason that the system chooses to automatically set the Memory Speed to DDR2-667 even though DDR2-800 modules are installed, is that by design the memory controller of the Intel 975X Chipset does not natively support DDR2-800 modules, but
>>Intel® 975X Express Chipset Datasheet - For the Intel® 82975X Memory Controller Hub (MCH)<< [Page 20]
This means, that from the point of view of the memory controller, operating the memory @DDR2-800 actually means overclocking it (with all potential side effects).
Basically, if your initial problem disappears as soon as you reduce the memory speed to DDR2-667, the design limitation of the memory controller may explain your findings.
2. Different memory modules
If I read your signature correctly, you are actually mixing two different kits/models of RAM (CM2X1024-6400C4DHX and CM2X1024-6400C4). This can work of course, but in practice it not necessarely does under all circumstances.
This list (-> http://ramlist.i4memory.com/ddr2/) indicates that there are at least 14 different module types/revisions of Corsair DDR2-800 / CL4 modules that utilize a wide range of different memory chips (Elpida, ProMos, Micron, Infinion, Powerchip, Qimonda, Samsung, Infinion etc.). Even though the superficial specifications for these chips appear to be pretty similar (DDR2-800 / CL5 / CL4), this does not necessarely mean that the modules will respond to the same operating conditions in the same way. There may be small difference in sub-timings/sub-latencies and/or the general responsiveness of the ICs which may affect the operating behaviour of the memory controller (which by the way also includes the PCI-Express interface which your video card is hooked up to).
And again: If running the system @DDR2-667 solves your issue, the possible explanation is that higher clock speeds may amplify (or trigger) potential performance problems that could have to do with the use of non-identical memory modules.
Furthermore: It is also possible that the memory controller's design limitations and the potential compatibility problems that may be attributed to mixing different modules types may reinforce each other in terms of reduced system performance.
3. The BIOS may have an impact as well
There has been known issue with the use of certain video cards in conjunction with 4GB of system memory on this mainboard:
https://forum-en.msi.com/index.php?topic=107301.0
https://forum-en.msi.com/index.php?topic=105955.0
https://forum-en.msi.com/index.php?topic=99818.msg798951#msg798951
What may have come out as graphics/display corruption in earlier BIOS Releases may come out as reduced system performance when using the latest BIOS Release. Of course, this is hard to prove, but I thought I'd mention it anyway. May I ask what amount of video memory your card has onboard?
Fortunately, there is a BIOS version that you could consider to try in this matter. It is not only the last BIOS Release that could be used in order to avoid the corruption issue, but it is (in my oppionion) the best BIOS Version that was ever released for the 975X Platinum PUE Mainboard: W7246IMS.716 [v7.1b6]. I have been using this mainboard for almost two years and have tested almost every BIOS Release that ever came out and I always went back to v7.1b6 as "ground zero".
It will properly support your E6600 (so you don't have to worry about that) and as far as I remember, there are no known compatibility issues with other components. So maybe, you want to give this a shot.
The bottom line is that in a worst case scenario, the problem you describe could be caused by all of the above things at the same time. You cannot really do anything about the 975X Chipset Specifications and the only way to rule out explanation #2 is to test modules that are actually identical (same model number, revision and memory chips). A test of the 7.1b6 BIOS Release is something you should consider. It may be the only way to test the BIOS Hypothesis.
This post turned out to be longer than I intended, but then again, I am well-rested after a good sleep and the wake-up coffee is kicking in pretty good.

Performance problems after installing XP Service Pack 3

Hello,
After upgrading my client XP-machine to Service Pack 3, I have serious performance issues working with ApEx. Firstly, establishing the connection to the ApEx Workspace and then logging in both are very slow. Navigating through the workspace works fine, however when I then open any page for editing and/or try to run it, again it is very slow. As we work with PL/sql Embedded gateway I have changed the parameter SHARED_SERVERS to 10, but this did not make any difference. Remotely connecting to this server in other ways such as ping, connecting to xmlpserver, mapping network drives and connecting to the database all work fine.
My collegues also working witk Service Pack 3 have no performance issues. However when I performed a rollback of the XP Service Pack 3, the performance issue was gone!
Does anyone know of any issues similar to this problem?
Regards,
Ben van Dort

This issue is probably related to an update of InternetExplorer by Service Pack 3. Working with Firefox instead of IE gives no performance problems whatsoever.
Version of IE after Service Pack 3: 6.0.2900.5512.xpsp_sp3_gdr.080814-1236CO

Performance problems after EHP4

Hello,
We have a small problem.
After installing EHP4 for ERP and EHP1 for Netweaver 7 on AIX Oracle installation, an increase in dialog response time is reported.
We upgraded last September 2009, and from then and to now, we have gone from an average of 800ms to 1200ms in dialog response time.
When we analyze transactions, there is no specific transaction that is the cause, it looks more like an allover trend, that the system in general has become slower.
When we look at fx. Earlywatch reports, it is quit obvious, that the u201Cproblemsu201D started just after implementing the EHP.
We are attacking this on several fronts, and I am looking on the sap basis part.
I was not a part of the upgrade team, so what I am looking into, is weather maybe some notes has been forgotten or something else. I am especially interested in notes and steps that should have been performed on Oracle, in connection with the EHP upgrade.
Is there anybody in here that have experienced similar problems, after applying EHPs?
Best Regards,
Kenneth
Edited by: Kenneth Nielsen on Jan 22, 2010 9:45 AM

Hi Kenneth,
In which area that you are having much interval in total rsponse time? If it is looking under DB time may be cause with Oracle bug fixes..check your all Oracle patches(mainly related to performance).
And explore the DB version and patch list that presently you had.

DB Performance Issues after 10g Upgrade in EBS Instance

We have upgraded our Database from 9i to 10g as first part of EBS 11.5.9 to 11.5.10.2 upgrade. Currently our production is running on 11.5.9 apps with 10g DB.
Facing performance problems now. one of the them is, one Valueset query not using funcion based index while fired from the front end. but the same query when collected from SQL trace tkprofed file and executed from SQL Plus, it uses all proper indexes. We are not getting the cause of this.
Had anyone faced same kind of issues before. please suggest.

we often notice massive performance problems with PrPro CS5 here.
e.g. last week we were shooting with a Sony NEX-VG10. (MediaInfo:)
Format: AVC
Format profile: [email protected]
Format settings, CABAC: Yes
Format settings, ReFrames: 2 frames
Format settings, GOP: M=2, N=13
Bit rate: 16.0 Mbps
Width: 1 920 pixels
Height: 1 080 pixels
Display aspect ratio: 16:9
Frame rate: 25 fps
After linking footage into PrPro plaback stutters.
PrPro is very often not responsive to the keyboard at all.
Sometimes PrPro needs some seconds before playback starts.
This way editing is a pain...
No fx in timeline, only one or two clips. Same behaviour if I play a clip in the source window.
Project and sequence settings are correct. Playback quality set to 1/4.
These problems occure in several projects with footage from different cameras.
PrPro works ok with this (PAL/SD-)footage for example - MediaInfo:
Format: DV
Commercial name: DVCPRO
Width: 720 pixels
Height: 576 pixels
Display aspect ratio: 16:9
About the computer:
Dell Precision WorkStation T5500
24 GB RAM
2 processors w/ 8 cores together: Intel Xeon CPU E5620 @ 2.40GHz
System: 250 GB (SSD)
Media: 2 TB (this is one normal internal hard drive, no raid)
NVIDIA Quadro 4000 (driver version 297.03)
connected to internet (is a must in this company)
connected to intranet, server (is a must in this company, too)
optimized for performance
windows firewall active
AVIRA Porfessional
What would PrPro force to work with HD footage?
Add an RAID? internal/external?
Upgrade to CS6?
Edncode footage to another codec before linking it into PrPro? (which codec? encode with AME?)
Buy a new processor? (i7? which one?)
Buy any Hardware pieces?
TIA for your guidiance and best regards.

Take a look at the Dell T7400 currently at rank # 568, 'Base2008PT1' on Benchmark Results. It is somewhat similar to your own system, but has more memory, a better video card and some raid0 arrays. Nevertheless, it is around 3.4 times slower than a fast system. My guess is that your system is even slower.
The material you try to edit is very demanding and requires a beefy computer. Even though there is nothing wrong with the dual Xeon E5620's, their clock speed works against you (I have the same CPU's in a file server, but that is far less demanding than editing), as does the amount of memory in the system. You can be helped with more disks, but don't expect miraculous performance improvements. But all little things help.
The alternative is a complete new system, but that can be pricey. Even if you build it yourself, see Planning & Building a NLE system it can be costly. It gives you very fast performance as demonstrated on the Reflections page and you should not get such a system from Dell or HP, unless you have unlimited funds.
