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.
Regards,
Chris

Explain plan looks different in steps 19 to 28. I am not sure why 10g have more steps

Hi
I have no experience in 8i. I do know 10g does costing different from 8i. So I think the other plan might got elliminated.
Normally when I see differences. I just collect statistics on the tables and the indexes and remove the hints. Hints are not good . This has helped me to solve few problems.

Performance issue after Upgrade from 4.7 to ECC 6.0 with a select query

Hi All,
There is a Performance issue after Upgrade from 4.7 to ECC 6.0 with a select query in a report painter.
This query is working fine when executed in 4.7 system where as it is running for more time in ECC6.0.
Select query is on the table COSP.
SELECT (FIELD_LIST)
        INTO CORRESPONDING FIELDS OF TABLE I_COSP PACKAGE SIZE 1000
        FROM COSP CLIENT SPECIFIED
        WHERE GJAHR IN SELR_GJAHR
          AND KSTAR IN SELR_KSTAR
          AND LEDNR EQ '00'
          AND OBJNR IN SELR_OBJNR
          AND PERBL IN SELR_PERBL
          AND VERSN IN SELR_VERSN
          AND WRTTP IN SELR_WRTTP
          AND MANDT IN MANDTTAB
        GROUP BY (GROUP_LIST).
   LOOP AT I_COSP      .
     COSP                           = I_COSP      .
     PERFORM PCOSP       USING I_COSP-_COUNTER.
     CLEAR: $RWTAB, COSP                          .
     CLEAR CCR1S                         .
   ENDLOOP.
ENDSELECT.
I have checked with the table indexes, they were same as in 4.7 system.
What can be the reson for the difference in execution time. How can this be reduced without adjusting the select query.
Thanks in advance for the responses.
Regards,
Dedeepya.

Hi,
ohhhhh....... lots of problems in select query......this is not the way you should write it.
Some generic comments:
1. never use SELECT
                   endselect.
   SELECT
into table
   for all entries in table
where.
   use perform statment after this selection.
2. Do not use into corresponding fields. use exact structure type.
3. use proper sequence of fields in the where condition so that it helps table go according to indexes.
    e.g in your case
          sequence should be
LEDNR
OBJNR
GJAHR
WRTTP
VERSN
KSTAR
HRKFT
VRGNG
VBUND
PARGB
BEKNZ
TWAER
PERBL
sequence should be same as defined in table.
Always keep select query as simple as possible and perform all other calculations etc. afterwords.
I hope it helps.

Pranaya

Performance problems after Update from 7.6.00.37 to 7.6.03.15

Hi,
after the Update from 7.6.00.37 to 7.6.03.15 in our live system we noticed a lot of performance problems. We have tested the new version before on our test system, but there don't noticed effects like this.
We have 2 identical systems (Opteron 64 bit, openSuse 10.2) with log shipping between them. We updated first the standby system, switched from online to standby (with copy of cold log) and started the new server as online system. After that we run a complete backup (runtime: 1 hour) for starting a new backup history and for activating autolog. Then
With the update we changed USE_OPEN_DIRECT to YES, but the performance of the system was very slow afterwards. After the backup it remains at a high load average (> 10, previous system had about 2-4), with nearly 100% of CPU usage for the db kernel process.
Next day we switched USE_OPEN_DIRECT back to NO. The system first runs better, but periodically rises up to a load average of 6 and slow down the performance of various applications (somebody says about 10 times slower). Here we also noticed a high usage (now 200-300%) of the db kernel process.
Our questions are:
1. Has something basically changed from 7.6.00.37 to 7.6.03.15, so that our various applications (JDBC, ODBC and Perl/SQLDBC partially on old linux systems with drivers from 7.5.00.23) don't reach same performance as before?
2. Are there any other (new) parameters, which can help? Maybe reducing MAXCPU from 4 to 3 for reserving capacities for the system (there is only one maxdb instance running)?
3. Is the a possibility to switch back to 7.6.00.37 (only for worst case)?
I have made some first steps with x_cons, but don't see any anomalies on the first look.
Regards,
Thomas

Hmm... that is really odd. When using USE_OPEN_DIRECT there is actually less work to do for he operating system.

Well of course there are bugs that have been found inbetween the release of both versions, but I am not aware of something like the performance killer.
We will have to check this in detail here.

Well - then I guess 'looking at the system' won't bring you far...

Great - let's see the warnings you get.
Let us also see the DB Parameters you set.

With the old version we had no problems with missing indexes or the general performance. Unfortunatly it is very difficult to extract some sql statements out of the JBoss applications. But even simple queries (without any join) runs slower, when the load average rises over 4-5.
Hmm... the question here is still, if the execution plans are good enough to meet your expectations.
E.g. for tables that you access via the primary key it actually doesn't matter how many rows a table has (not for MaxDB at least).

Sounds like the I/O is your most suspect aspect for overall system performance...

Ok - so this is next to no testing at all when it comes to performance.
> An UPDATE STATISTICS over all db users seems to change nothing. At the moment the system remains markedly slow and we are searching for reasons and solutions. Another attempt will be the change of MAXCPU from 4 to 3.
Why do you want to do that? Have you observed any threads that don't get a CPU because all 4 cores are used by the MaxDB kernel?

Search Service Application problems after upgrading from Foundation to Enterprise edition of SharePoint 2013

Hi all. I have been searching for days for a solution to a problem I am having with SP2013 Enterprise edition.
We recently upgraded from SP2013 Foundation to SP2013 Enterprise. After the upgrade, the search services are no longer working and we are receiving many application log entries indicating the following:
Application Server Administration job failed for service instance Microsoft.Office.Server.Search.Administration.SearchServiceInstance (ea2019ef-bb9e-4efe-85ee-5d2307406f31).

as well as:

I have tried to remove the search service application and recreate it, and even though the SharePoint Central Administration states that it was created successfully, I am still getting the same errors in the log. If I go to the Search Service Application
Search Administration page, the "System Status" shows the following message:
The search service is not able to connect to the machine that hosts the administration component. Verify that the administration component '0359af35-0982-4ede-8838-b1d390e915bf' in search application 'Search Service Application' is in a good state and
try again
Additionally, under the "Search Application Topology" section, it states "Unable to retrieve topology component health states. This may be because the admin component is not up and running" which I assume is normal if the admin is not
running.
Does anyone know how I can resolve this problem?
Thanks!

Hi Joaquin,
According to your description, the error occurred when you re-created the Search Service Application.
Based on the error message, I recommend to verify the things below:
   1. Check if the association between the Search Service Application proxy and the web application is configured.
Please go to Central Administration > Application Management > Configured service application associations > Click Default to see if the Search Service application is checked.
   2. Change the app pool for the Search Service Application to SharePoint Web Services Default in the properties of the Search Service Application.
Please go to Central Administration > Application Management > Manage service applications > Highlight the Search Service Application > Click Properties in the ribbon > Change
the two app pool to SharePoint Web Services Default: App Pool For Search Admin Web Service and Application Pool for Search Query and Site Settings Web Service.
    3. Run PS command to check if the search admin timer job is enabled: Get-SPTimerJob
job-application-server-admin-service | fl. If it is not enabled, use PS command to enabled it and then reset Internet Information Services: Enable-SPTimerJob job-application-server-admin-service.
Best regards.

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.

Mail flow problem after upgrade from cu1 to sp1

I have update Exchange server 2013 CU1 to SP1 (CAS Role). After upgrade mail cannot flow. all the mail are stuck.
CAS server use to mail flow outside and receive from outside. but The problem is this CAS server mail flow not work after upgrade exchange server 2013 CU1 to SP1.
Please give suggest.
Thanks

I didn't connect to queue viewer as because the version of exchange 2013 server are different. in the environment two CAS server and two Mailbox server. i just update one CAS server into SP1. and another CAS in CU3. Mailbox 01 is CU3 and Mailbox 02 is CU
1. So their is version difference in the environment.
So, when i update CAS server to SP1. That server is not working for mail flow.
Please suggest.

Performance suffering after upgrading from 10.4.10 to 10.4.11

I've got an 800 MHz Powerbook G4 with 1GB of ram, which I use mostly for checking email, surfing the internet, and watching videos (via S-Video out to my TV).
It has always been plenty fast for what I need to do, until I upgraded from 10.4.10 to 10.4.11. Now videos are stuttery; it's painful to even watch Youtube videos, and I can't watch Hulu videos at all. Everything is a bit slower, not just video; navigating in the finder is now somewhat sluggish, file copies take longer, etc.
Nothing other than the OS version has changed, and no other upgrade I've done has resulted in a performance decrease. I hear this is the last 10.4 update. Is there any way I can revert to 10.4.10 without reinstalling the OS entirely?

Hi dojiijii, and a warm welcome to the forums!
Ii\t appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...
http://docs.info.apple.com/article.html?artnum=107120
Just be sure to select Preserve Users & Settings.
You could just p the 10.4.10 Combo upgradw if you desire/...

But I think the problem is elsewhere!

Serious performance problems after updating from 10.5.6 to 10.5.7

I've got a Macbook Pro C2D 15" (late 2006). After updating the system from 10.5.6 to 10.5.7 and quicktime to 7.6.2, I experience serious performance problems which I have never seen before:
-From time to time, kernel_task has peaks in activity monitor (consumes a lot of CPU). In that moment, the mouse hangs for a short moment and audio playback is distorted/has drop outs.
-Recording audio consumes a lot of CPU (independent of the audio application).
-Video playback consumes a lot of CPU, regardless if I use VLC or the quicktime player.
Any idea what could be done? Thanks in advance.

After a few days of using CoolBook I report that my 1st generation MacBook Air is now reliable and never overheating, regardless of environment conditions.
I must point out that I do believe that it really is something new in 10.5.7 that is causing this problem as my environmental conditions have not changed and even Summer in Dublin still sees temperatures no more than 72F/22C. I am now in Madrid, where the environment is quite different, and I am still having no problem with kernel_task spinning.
I plan on reporting my problem to Apple anyway and being aggressive about the issue as MacLovinRanga did in this thread (http://discussions.apple.com/thread.jspa?messageID=9647353#9647353). Perhaps many/all of those of us having this problem will obtain new MacBook Airs.

Problem after upgrade from patch level 36 to 43

Hi,
Recently our system is upgraded from 36 to 43 patch level. After this there are problem in doing hiring action, IT0000 is saving but the next infotype IT0001 does not gets saved and also no error message. So, really not able to figure out what could be the problem.
I was debugging the standard code i.e once the 'save' button is clicked in IT0001 in PA40, but in vain. I am not able to find out where or in which program/include the data gets saved in PA0001. If any one aware of this please let me know.
Since IT0001 is not getting saved, there are probs with IT0007 and IT0008.
Please let me know your views.
Thanks,
Arunsri

Hi Raju,
Thanks for the reply. Ya, the problem was not due to upgrade,but some other issue. Not able to find till now. I checked IGMOD features and it is in 'Active' mode only. No luck.

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
Check also the following note resp. white paper:

Problem after upgrading from 4.2 to 4.2.2

I just recently did an upgrade from 4.2 to 4.2.2 running on an Appliance. After the upgrade all the services do not load up. Running a "show app status LMS" always comes up with a message saying daemon manager is not fully intialized. The DCRServer process is just hanging with the status "waiting to initialize".
I am able to GUI in but can't use view any of the managed devices due to DCRServer in a hung state. I have restared LMS application multiple times. I have stopped LMS application and then reloaded the box. The issue still keeps occuring, im going to raise a TAC case but was wondering if anyone else has come across this issue?

Are you still facing the above issue ?
If yes send me the below information.
output of pdshow

AUTO_RUNSTATS: problems after upgrade from 8.2 to 9.5

Hello guys,
We're appreciating a problem in our recentley upgraded databases 9.5
We've upgraded from release 8.2 and we have activated the following parameters:
db2 UPDATE DB CONFIG USING AUTO_MAINT ON AUTO_TBL_MAINT ON AUTO_RUNSTATS ON
Although we don't see auto_runstats running in database. How can I activate this issue? Isn't it enough to activate these parameters?
regards,
Filipe

Hello Filipe,
have a look at your dump directory, under events you find file like db2optstats(n).log
db2 runstats on table DB2DDP.STMTS

this is a manual runstats, you will also a ot of fabricated runstats.
