Query performance difference with same script in two servers

Dear all,
I have problem with an INSERT Procedure. I have 2 servers, say Server A and Server B, In Server A the query execution will be finished in 4 minutes where in the Server B the same Query its taking more than 2 hours.
If I look into the execution plan in both servers, it looks different.
Both have the Default Parallelism settings.
Cost Threshold for Parallelism : 5
Locks : 0
Max Degree of Parallelism : 0
Query Wait : -1
What causing to slow down the process? Is the parallelism slowing down the process?
When I look into the SERVER A's active running processes in management studio, I found that there are 8 INSERT Queries running with only 2 RUNNABLE and 6 SUSPENDED. Anything is getting locked out or Waiting?
Please help and suggest my a solution for it. Thanks in advance.
Regards,
kranthi kumar G.

Thanks Tony for your reply. Here are my answers.
Are we talking a large amount of inserts?
YES
What is the autogrowth settings for the database files on the two Servers?
Autogrowth by 10%
The Server you are having an issue with, are the any triggers on the Tables?
No.
Is there a background or other trace running on the slow Server that could be impacting performance?
Yes, we are running a monitoring tool to check the performance of the load.
Is there another database on the slow Server causing issues?
No.
This could be a hardware issue; have you use perfmon to see if there are any disk queues?
We will check with our DBA on this.
What is the Raid Configuration? Are the files on a single spindle? If so what is the fragmentation state of any single spindle volume?
There is no Rain Configuration. Its a Windows Azure A7.
Are you automatically updating statistics on the slow Database?
Yes.
Is the Anti Virus Software on the Slow server scanning the data files?
Yes, but not on the database level.
Regards,
kranthi.

SQL query performance difference with Index Hint in Oracle 10g

Hi,
I was having a problem in SQL select query which was taking around 20 seconds to get the results. So, by hit and trail method I added Index Oracle Hint into the same query with the list of indexes of the tables and the results are retrieved with in 10 milli seconds. I am not sure to get How this is working with Indexes Hint.
The query with out Index Hint:
select /*+rule*/ FdnTab2.fdn, paramTab3.attr_name from fdnmappingtable FdnTab, fdnmappingtable FdnTab2, parametertable paramTab1 ,parametertable paramTab3 where FdnTab.id=52787 and paramTab1.id= FdnTab.id and paramTab3.id = FdnTab.id and paramTab3.attr_value = FdnTab2.fdn and paramTab1.attr_name='harqUsersMax' and paramTab1.attr_value <> 'DEFAULT' and exists ( select ParamTab2.attr_name from parametertable ParamTab2, templaterelationtable TemplateTab2 where TemplateTab2.id=FdnTab.id and ParamTab2.id=TemplateTab2.template_id and ParamTab2.id=FdnTab2.id and ParamTab2.attr_name=paramTab1.attr_name) ==> EXECUTION TIME: 20 secs
The same query with Index Hint:
select /*+INDEX(fdnmappingtable[PRIMARY_KY_FDNMAPPINGTABLE],parametertable[PRIMARY_KY_PARAMETERTABLE])*/ FdnTab2.fdn, paramTab3.attr_name from fdnmappingtable FdnTab, fdnmappingtable FdnTab2, parametertable paramTab1 ,parametertable paramTab3 where FdnTab.id=52787 and paramTab1.id= FdnTab.id and paramTab3.id = FdnTab.id and paramTab3.attr_value = FdnTab2.fdn and paramTab1.attr_name='harqUsersMax' and paramTab1.attr_value <> 'DEFAULT' and exists ( select ParamTab2.attr_name from parametertable ParamTab2, templaterelationtable TemplateTab2 where TemplateTab2.id=FdnTab.id and ParamTab2.id=TemplateTab2.template_id and ParamTab2.id=FdnTab2.id and ParamTab2.attr_name=paramTab1.attr_name) ==> EXECUTION TIME: 10 milli secs
Can any one suggest what could be the real problem?

Purushotham

Sorry,
The right query and the explain plan:
select /*+rule*/ FdnTab2.fdn, paramTab3.attr_name from fdnmappingtable FdnTab, fdnmappingtable FdnTab2, parametertable paramTab1 ,parametertable paramTab3 where FdnTab.id=52787 and paramTab1.id= FdnTab.id and paramTab3.id = FdnTab.id and paramTab3.attr_value = FdnTab2.fdn and paramTab1.attr_name='harqUsersMax' and paramTab1.attr_value <> 'DEFAULT' and exists ( select ParamTab2.attr_name from parametertable ParamTab2, templaterelationtable TemplateTab2 where TemplateTab2.id=FdnTab.id and ParamTab2.id=TemplateTab2.template_id and ParamTab2.id=FdnTab2.id and ParamTab2.attr_name=paramTab1.attr_name)

Query performance difference -- CPU time difference on two servers

Two SQL servers, server A & B, Hardware information as below:
Server A: Clustered. Two physical processors (4 cores). RAM 64GB, SQL Server max memory: 58GB.
Server B: Standalone. One physical processor (4 cores). RAM 16GB, SQL Server max memory: 10GB.
The two databases on A & B are identical (using backup & restore method), same query execution CPU time are different, it is slower on the cluster server with more CPU & Mmeory. I tried many times and all same result, I also tried run DBCC DROPCLEANBUFFERS
& DBCC FREEPROCCACHE before running the query.
When I run the query, on Server A (Slow one), CPU usage is at 20% ~30%. RAM usage is 14%. It is new set up environment so just me using it now.
When I run the query on Server B (Fast one), CPU usage is 40%, RAM usage is 85%.
Both two servers have SAN connected storage.
Query execution plan is exactly same on two serers.
Could someone give me some advise how to troubleshoot this problem? Any suggestion is appreciated a lot! Thanks a lot!
FYI, Below are the statistics when running same query in same DB on two servers:

hi, Vivian_Vivian
i just want to ask you
which sql version do you use？
have you ever tried xevent before？？
if you use the sql2k8 or latter you can try xevent out to find somgthing clues about your cpu time problem
i provide you the script，pls post your output in the xevent here so that we could judge what the head of the problem is

Unable to monitor two databases with same name on two different hosts

I have got two databases with same name on two different hosts. I added one database to the list of monitored databases. Now If I try to add the other one , I get the message that the database is already being managed.
Can't we monitor two databases with same name on two different hosts?

you can... while saving the target,give a different name.. for eg target-2

Performance difference with SSL/HTTPS

My company has an application deployed on two different servers. When using https, the faster server (more ram, faster CPU, newer version of Solaris) takes between 6 and 12 seconds longer to serve the same JSP. Both instances are hitting the same DB, using the same EJBs, same services, everything is the same. What could be the cause of this?

Sounds like a configuration problem.
Does a HelloWorld JSP have the same overhead?
Is there web server in front of the slow server?
Is the problems erver clustered?
Is there a hardware load balancer in front of the problem server?
Is there a DNS misconfig?
If you tail logs when you hit the server does the request arrive
immediately?

Poor query performance only with migrated 7.0 queries

Dear Team,
We are facing a serious query performance issue after migration of queries from 3.5 to 7.0.
I executed a query in 3.5 with some variable values which takes fraction of seconds to display the output. But the same migrated query with same variable entries is taking very long time and giving time out error.
We are not using any aggregates in the InfoProvider level.
Both the queries are based on same cube but 3.5 query is taking less time and 7.0 is taking very long time if more selection is done.
I checked for notes where I didn't find specific note for this particular scenario. I found notes only for general query performance improvement.
I want to know the reason why only in 7.0 the same 3.5 query is taking a long time and giving time out error. And please suggest some notes or suggestions related to this scenario.
Regards,
Chan

Hi,
Queries in BI 7.0 are almost the same as queries in 3.x format.
inorder to check if the problem is in the query runtime (database time) or JAVA runtime (probably rendering) you should try running it from RSRT once in JAVA web and once in ABAP web.
if the problem is only with JAVA web, than u should take the URL and add &profiling=X at the end.
after the query execution u can use statistics which will be shown at the top of the page.
With my experience, the problem is in the rendering phase of the query. Things that could be done is to limit the number of rows shown at each page, that could be done by changing the 0ANALYSIS web template - it's one of the web template parameters.

Same certificates for two servers using Sun Java WS 6.1sp5 with Crypto card

Hi,
I have 2 Sun java webserver 6.1 sp5 installed on two machines as :
Single webserver1 instance on hostmachine1
Single webserver1 instance on hostmachine2.
(both instance names are same)
I have created server certificate and installed it using External cryptographic module: Sun Crypto Accelerator 500 on hostmachine1.
It is perfectly working fine.
Now,for hostmachine2, I created trust database with same password as for hostmachine1, I copied the two files
https-webserver1-hostmachine1-key3.db and
https-webserver1-hostmachine1-cert8.db from hostmachines1 and then put on the hostmachines2 (in an serverroot/alias folder ) and then renamed them as
https-webserver1-hostmachine2-key3.db and
https-webserver1-hostmachine2-cert8.db
Then I went to preferences->Edit socket listen, but security was disabled.
I restarted the webserver, but security was still disabled.
What is the problem??
Please inform me as well as at my email address [email protected]
Please do reply me as I am waiting anxiously.
Thanks.
Taqi

Hello,
The problem you are reporting is not expected.
Hope you are not trying on admin server.
I am not sure why you removed all files from alias directory.
Please do the following in a fresh installation:-
1) install ws6.1sp5.
2) copy cert and key db from the working systems to the alias
directory of the instance.
3) move the db files to the new name (make this name right).
4) through admin server GUI select instance (Manage server).
5) go to edit listen socket.
6) turn on security and select OK.
7) then press Apply button.
8) then press Apply changes.
9) it will restart your instance server and will ask you for the password.
10) supply the security password of the first server.
11) it will restart your instance server in https mode.
This works fine.

How to create logical directories with same name on two databases

Hi,
OS: Windows
Oracle Version : 10g
I have to databases in one oracle home. I have created some logical directories in one database. When I am trying to create logical directories with same name in another database, it is overwriting the first database directory paths with the second one
Can't we create directories with same name but different path in two databases on one machine?
Pls suggest me on this
Regards,
Vijay

I am trying to create logical directory using CREATE
DIRECTORY statement. I am very much aware that the
create directory statement doesn't create directory
on OS. But we can attach the physical directory on OS
to logical directory in oracle
My requirement is to create logical directories in
oracle mapping the OS directories. Both the
databases, wil have same logical directory names but
different OS directory mappingsIf I understand you correctly, you can do this:
On DB 1
CREATE OR REPLACE DIRECTORY same_dir_name as 'C:\myoracle\mydir1';
On DB 2
CREATE OR REPLACE DIRECTORY same_dir_name as 'D:\myoracle\mydir2';
What stops you from doing that ?
Note: If what you have is one database but different connections, then you are connecting to one database. The above second statement will drop and replace with the first one

Merging two Podcast with same episodes and two different feed addresses

Version 7.0.1.8 has certainly problems in the download of new podcast episodes.
I'm having a lot of difficults - the last one beeing forced to unsubscribe one podcast and subscribe it again with another feed address. Now I have two podcasts in ITunes with same name. In Windows Explorer, all episodes are together - in the iTunes menu, all episodes are separated, each one downloaded the same episode, and with a number one appearing in the file name under the folder where the programs are stored. I tried to merge both subscriptions, but it's impossible.
Does anybody knows how to do this? Need I download all episodes again?

Two browser with same site having two different session

Hai Experts................
I have a problem that with session............
when we logged in one site with our username and password, and
then i try to log in same site with other username and password in another browser
then how to know is there any browser is open with any other username and password in the same site.
I want to give this checking in the client side.....

You could use cookies, but this will only allow you to detect multiple uses of the same browser like two instances of IE. This won't work if you are using IE and you open another different browser such as Firefox.
I think you are out of luck :)

Performance difference with my MBP 15" 2010 and the new 2011 one(gaming?)

Hey guys,
I have a 2.67 i7 2010 15" MPB(the higher end model)that I got last year. I use it for work and for college but I also like to play games on it.
I recently got an Apple newsletter as I noticed the huge performance boost of the newer models. I went to a review site and my specific model nearly doubled in benchmark scores with the newer model. That doesn't seem like something that would normally happen. It seems like a rarity thats just too good to ignore. And this summer with the semesters being over I probably will go back to full on gaming(probably Portal 2 and WoW for the summer).
My question to you is, since I can't go by the opinion of one site, what is the performance difference between the 2010 model I have and the newer 2011 one? Basically I am wondering if its worth it to sell it for several hundred dollars less than I payed for it and get the newer model now, or wait until 2012 to get the newest model then(if its going to be an even bigger difference in performance)?
Excuse my poor judgement if I'm wrong, I probably seem like a maniac for using this comp for a year and already wanting to get the newer model. Its just that a lot of sites are making it seem like my model is fodder compared to the newer ones, and if so I might not let this offer pass by.

bump for good measures!

Output from same script on two different platforms produce different outputs.

I'm running a command prompt script on two different platforms (Windows 7 desktop and a Microsoft Server 2008 R2 Enterprise platform) and the output the script produces is different on each platform.
Specifically; the script is
For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set mydate=%%c-%%a-%%b)
For /f "tokens=1-2 delims=/:" %%a in ('time /t') do (set mytime=%%a%%b)
echo %mydate%>> log.txt
echo %mytime%>> log.txt
and the output from the Windows 7 desktop is:
2014-07-31
0249 PM
While the output from the 2008 server is:
ECHO is on.
0249 PM

Hi Dave,
There's some very good learning resources here:
http://technet.microsoft.com/en-us/scriptcenter/dd793612.aspx
Also, there's a script repository full of examples you can learn from and tweak to meet your needs here:
http://gallery.technet.microsoft.com/scriptcenter
As an additional suggestion, I'd highly recommend upgrading PowerShell on Win7 and WS2008R2 to v4. v2 was okay, but v4 makes life much easier (make sure you read the system requirements first though, there's still a few incompatibilities):

Difference in LOCL print preview for same script in two different systems

Hi All,
When I am testing a dunning letter ( Custom sapscript) in my testing system the LOCL print preview is correct...When I am testing it in my development system by taking print preview from LOCL it is not printing a uline and some line item headers...
There is one text element for printing line item header.
U1....ULINE(73)
T0    &vline& ....&T_MATNR&..
T3    &vline&
UL   &ULINE(73)
IN Development sytame in print preview every thing is perfect except the above portion the first uline and vline are not getting printed and as a result next vline and uline are dispalyed a bit above .. I am unable to understand why one uline is not printed but the othe one is printed as we are using HELVE12 in both cases and above all why in test system this problem is not occuring..
I checked and am 100% sure there is no difference between the layout versions in the two sapscripts...Also checked most of the SPAD configs in two systems and found them same..
Can you give me any idead about the reason for the diffrence in print preview as in both cases it will consider the printer installed on the local desktop....
Just we use citrix metaframe to log in SAP but that should not be the reason as thne problem would be in both system..
Please help me out...
Thanks and Regards
Sweta

Hi ,
I already mentioned that I am selcting LOCL ( Device type Sapwin) in both cases so in both cases it is considering the printer installed on the local system...
Can anyone tell me specific spad config or anything else which I need to compare in both systems..

Query Performance difference in two DB

Hello gurus,
Im executing a query in two diferent databases. The query is exucting much faster in DB A then DB B. Im not sure if this is because of the configuration of the DB. I tried getting the query plans and they are completly different. Can any body tell me why is this?, can it be because of the differenci in resources and config?. Also, the Db are as fallow
DB A: 2 node RAC 9.2.5, 3gb RAM each node, intel core2 at 2.0 ghz, windows2003
DB B: No rac, 9.2.1, 1 gb RAM, Xeon 2.8 ghz windows 2003
If this is because of the HW ??

In general, query plans will be different because
- The schema is different (i.e. indexes are missing on one database)
- The data volume is different (i.e. one system has more data than another)
- The statistics are different
Query plans should not change because of hardware configurations (other than the corner case where you gather system statistics and those statistics lead Oracle to pick a different path, which generally requires significantly faster I/O subsystems on one of the two machines).

Same script against two applications, two diff results

Hi All,
One calculation script against XXX application it is not giving expected,not giving any result, but I created another application “Testapp” and run the same calc script against “Testapp” application it is giving the expected result. Both applications are same members, properties everything. I didn’t understand the issue. Any ideas please.
Regards,
Sravan Kumar.

Hi Sandeep,
1. Are the setting in cfg files same for both the applications.
Both applications are in same server and using the smae cfg file.
2. When you had run the calc script, was system consuming same amount of resources i.e processor , RAM ..etc. for both application at two different times. Check ,any parallel execution happening with 1st application's calc script.
System OS is Linux, I dont have much idea of linux like how to see the RAM ,processing etc. Is there any way to find.
3. Finally, you can check for server end, anything happened when you ran 1st application's calc script, by referring to OS logs.
No idea of Linux server log files.
If you provide the detailed information is appriciated.
Hi Glenn,
I'll ask the silly question. Do you have sut updatecalc off on in both scripts? If not, it's possible intelligent calculationis turned oon. In the first cube, the values would be calculated and would not be affected by your calc. In the second new db, they would not have been
I have used the updatecalc off option also. But no result for first application and result for second application.

Sravan Kumar.
