Significant difference in response times for same query running on Windows client vs database server
I have a query which is taking a long time to return the results using the Oracle client.
When I run this query on our database server (Unix/Solaris) it completes in 80 seconds.
When I run the same query on a Windows client it completes in 47 minutes.
Ideally I would like to get a response time equivalent on the Windows client to what I get when running this on the database server.
In both cases the query plans are the same.
The query and plan is shown below :
{code}
SQL> explain plan
2 set statement_id = 'SLOW'
3 for
4 SELECT DISTINCT /*+ FIRST_ROWS(503) */ objecttype.id_object
5 FROM documents objecttype WHERE objecttype.id_type_definition = 'duotA9'
6 ;
Explained.
SQL> select * from table(dbms_xplan.display('PLAN_TABLE','SLOW','TYPICAL'));
PLAN_TABLE_OUTPUT
| Id | Operation | Name | Rows | Bytes |TempSpc| Cost (%CPU)|
| 0 | SELECT STATEMENT | | 2852K| 46M| | 69851 (1)|
| 1 | HASH UNIQUE | | 2852K| 46M| 153M| 69851 (1)|
|* 2 | TABLE ACCESS FULL| DOCUMENTS | 2852K| 46M| | 54063 (1)|
{code}
Are there are configuration changes that can be done on the Oracle client or database to improve the response times for the query when it is running from the client?
The version on the database server is 10.2.0.1.0
The version of the oracle client is also 10.2.0.1.0
I am happy to provide any further information if required.
Thank you in advance.

There are NO queries that 'run' on a client. Queries ALWAYS run within the database server.
A client can choose when to FETCH query results. In sql developer (or toad) I can choose to get 10 rows at a time. Until I choose to get the next set of 10 rows NO rows will be returned from the server to the client; That query might NEVER complete.
You may get the same results depending on the client you are using. Post your question in a forum for whatever client you are using.

Huge difference in Execution time in same Query with different Parameter
Hi Experts,
We are facing an unique problem once we are executing the query in HANA SQL prompt. This Query was generated from BObj and executing in HANA system. Once this query running with following condition, it is taking almost 7-00 minute to execute and returning around 924 rows.
<< WHERE
Table__1."LOGSYS" IN ('RKGCLNT102')
AND
Table__1."CompanyCode" IN ('7240','7245')
AND
Table__1."Plant" IN ……………… >
However if we run the same query with some different plant, It is taking only 2 second. Please find the Query here.
<< WHERE
Table__1."LOGSYS" IN ('RKGCLNT102')
AND
Table__1."CompanyCode" IN ('7245','7600')
AND
Table__1."Plant" IN ……………… >
This is really an unexpected behavior and we are not able to get the actual reason why it is behaving like this.
Could anyone please help to analyze this issue to fine the root cause.
Thanks in Advance.

Satrajit.Hi there
Unfortunately you provided too few information to analyze the issue.
Maybe the underlying tables have very skew data and the first select has to read a larger share of the base tables.
Maybe the columns had been unloaded before and the first query had to load them into memory first.
Is the runtime always bad with the one and always good with the other set of parameters?
Have you checked the PlanViz for both versions? How do these differ?

Response time for Error Messages - Please Help
Hi
I have a PRO C application talking to an Oracle database.
The Response time for successful query is within desirable limits.
But when there is a error condition (eg SQLError -3113,or connection refused) it takes more than 9 minutes for the database to respond with the error code.
This condition is observed with only one database while the others are working fine.
What is the reason for this? Can’t it be reduced?
Regards
Davidever been faced with the same problem ?
Why deleting ? It that only one way to fix this problem ?
What are the others doing in such cases. Or am I the only one person
where has this special problem on the world. Becides I dont believe
in solving the problem through removing mentioned directory and
reinstalling. Nevertheless I will try it. I let you know about the result.

How to obtain the Query Response Time of a query?
Given the Average Length of Row of tables and the number of rows in each table,
is there a way we get the query response time of a query involving
those tables. Query includes joins as well.
For example, suppose there 3 tables t1, t2, t3. I wish to obtain the
time it takes for the following query:
Query
SELECT t1.col1, t2.col2
FROM t1, t2, t3
WHERE t1.col1 = t2.col2
AND t1.col2 IN ('a', 'c', 'd')
AND t2.col1 = t3.col2
AND t2.col1 = t1.col1 (+)
ORDER BY t1.col1
Given are:
Average Row Length of t1 = 200 bytes
Average Row Length of t2 = 100 bytes
Average Row Length of t3 = 500 bytes
No of rows in t1 = 100
No of rows in t2 = 1000
No of rows in t3 = 500
What is required is the 'query response time' for the said query.I do not know how to do it myself. But if you are running Oracle 10g, I believe that there is a new tool called: SQL Tuning Advisor which might be able to help.
Here are some links I found doing a google search, and it looks like it might meet your needs and even give you more information on how to improve your code.

Strange response time for an RFC call viewed from STAD on R/3 4.7
Hello,
On our R/3 4.7 production system, we have a lot of external RFC calls to execute an abap module function. There are 70 000 of these calls per day.
The mean response time for this RFC call is 35 ms.
Some times a few of them (maybe 10 to 20 per day) are way much longer.
I am currently analysing with STAD one of these long calls which lasted 10 seconds !
Here is the info from STAD
Response time : 10 683 ms
Total time in workprocess : 10 683 ms
CPU time : 0 ms
RFC+CPIC time : 0 ms
Wait for work process 0 ms
Processing time 10.679 ms
Load time 1 ms
Generating time 0 ms
Roll (in) time 0 ms
Database request time 3 ms
Enqueue time 0 ms
Number Roll ins 0
Roll outs 0
Enqueues 0
Load time Program 1 ms
Screen 0 ms
CUA interf. 0 ms
Roll time Out 0 ms
In 0 ms
Wait 0 ms
Frontend No.roundtrips 0
GUI time 0 ms
Net time 0 ms
There is nearly no abap processing in the function module.
I really don't uderstand what is this 10 679 ms processing time especially with 0 ms cpu time and 0 ms wait time.
A usual fast RFC call gives this data
23 ms response time
16 ms cpu time
14 ms processing time
1 ms load time
8 ms Database request time
Does anybody have an idea of what is the system doing during the 10 seconds processing time ?
Regards,
OlivierHi Graham,
Thank you for your input and thoughts.
I will have to investigate on RZ23N and RZ21 because I'm not used to use them.
I'm used to investigate performance problems with ST03 and STAD.
My system is R/3 4.7 WAS 6.20. ABAP and BASIS 43
Kernel 6.40 patch level 109
We know these are old patch levels but we are not allowed to stop this system for upgrade "if it's not broken" as it is used 7/7 24/24.
I'm nearlly sure that the problem is not an RFC issue because I've found other slow dialog steps for web service calls and even for a SAPSYS technical dialog step of type <no buffer>. (what is this ?)
This SAPSYS dialog step has the following data :
User : SAPSYS
Task type : B
Program : <no buffer>
CPU time 0 ms
RFC+CPIC time 0 ms
Total time in workprocs 5.490 ms
Response time 5.490 ms
Wait for work process 0 ms
Processing time 5.489 ms
Load time 0 ms
Generating time 0 ms
Roll (in+wait) time 0 ms
Database request time 1 ms ( 3 Database requests)
Enqueue time 0 ms
All hundreds of other SAPSYS <no buffer> steps have a less than 5 ms response time.
It looks like the system was frozen during 5 seconds...
Here are some extracts from STAD of another case from last saturday.

All,
I am in a predicament with internet browsing speeds...We have a 3rd party look after our line and internet facing f/w so I cant troubleshoot them, so at the moment Im looking at ISA as the potential bottleneck - we have a fairly standard environment:
Internal > Local Host > Perimiter n/work > Firewall > Internet
I have been running custom reports on the ISA server to see what data can be collected - I have noticed that "Average response time for non cached requests" (traffic by time of day) can be as high as 76 seconds!!!!!! Cached hits are between .5
and 2 seconds.
I have also coonfigured a connectivity verifier which is also flagging slow connectivity, massively over the >5000ms and also reporting "cant resolve server name on occassions- and this is configured for
www.Microsoft.com --- DNS ???!?!, however I have looked through DNS (no obvious errors / config issues) which I can see
I have run the BPA on ISA server to ensure its Health - - connectivity verifier errors flagged timeouts to microsoft.com as expected...
Can anyone advise any obvious areas to investigate as Im struggling! - as always the 3rd party have told us the internet pipe is fine :OProblem resolved.
DNS forwarders have been changed on the ISA server / DNS and this has improved lookup speed considerably.
thanks all :) -

SLR - transaction response time for all appl. servers together
Hi,
we want to have in SLR response time for defined transaction. We have activated necessary steps for monitoring transactions, started CPH and we can see in SLR average response times.
We have several application servers and we want to have in SLR TOTAL response time for all appl. servers together.
Is it possible? What is necessary steps to do it?
Thanks for all hints.
Regards,
RomanHi Andreas,
Another way to approach this would be to use CCMS transaction monitoring by maintaining table ALTRAMONI (in the satellite system) as described here: http://help.sap.com/saphelp_nw70/helpdata/en/b3/468e3b093d4031e10000000a11402f/content.htm
In RZ20 you'll be able to see the last 24 hours of performance data in a 1-hour granularity, as well as the last 30 minutes in a higher granularity. Depending on your requirements you can then configure alerting so that you get an email when performance passes a certain threshold.

Hello all,
Can you please tell me how can I see the total running time for a query?
What other transactions besides ST03 and RSRT with statistics on?
Points will be assigned
Thanks
RamonaHi........
You can use ST03N -> BW System Load
Depending on the time frame you select, you get historical data or
current data.
To get to a specific query you need to drill down using the InfoCube
name
Use Aggregation Query to get more runtime information about a
single query. Use tab All data to get to the details.
(DB, OLAP, and Frontend time, plus Select/ Transferred records,
plus number of cells and formats)
Also You can get it in RSRT,RSRTQ...

On our R/3 ECC6 production system ,we have one aRFC call by external system,there are 200000 times per day.
and the response time for the RFC call is 35ms ,Some times its response time(commit time) are much longer and up to 2 seconds.
There is very simple code for the RFC as shown below
insert ztable from table lt_internal_table.
commit work
call function 'function_name'
starting new task 'N'.
tables
it_tab = lt_internal_table.
Regards,
ShiChunQingDear Randorlf ,
Now i can determine that statement "commit work" have a high cost some times.
I write a simple report as show below,
One high cost will occurs per several minutes.
report ztest.
do 10 times.
GET RUN TIME FIELD t1.
INSERT ytest_table FROM TABLE lt_tab.
GET RUN TIME FIELD t2.
t1 = t2 - t1.
WRITE:/ 'insert:',t1,sy-uzeit.
COMMIT WORK.
GET RUN TIME FIELD t3.
t2 = t3 - t2.
WRITE: 'commit:',t2,sy-uzeit.
enddo.
Run results:
insert: 879 16:23:02 commit: 1,713 16:23:02
insert: 1,607 16:23:05 commit: 4,434 16:23:05
insert: 1,265 16:23:08 commit: 3,790 16:23:08
insert: 648 16:23:11 commit: 1,195 16:23:11
insert: 659 16:23:14 commit: 390,208 16:23:15
insert: 640 16:23:18 commit: 1,032 16:23:18

Query on a table runs more than 45mins(after stats) and same query runs 19secs(before stats - rebuild) - Not sure what the cause is.
- Analysed the explain the plan
- different explain plan used afterr stats gather.
Any idea what could be the cause with this kind of difference.
Thank you!What is the difference you see in the explain plan ? Where it spends most time. All these needs to be analysed.

TM does not work like that.
If you want files to use later.. do not use TM.
Or do not use TM to the same location. Plug a USB drive into the computer and use that as the target for the permanent backup.
Read some details of how TM works so you understand what it will do.

Use a clone or different software for a permanent backup.

What privileges for the DB account used by client connect to server?
Hello, After I installed the SBO server packages, I found that it must set DB account in the client side.
I had tried 'sa' account, it works. but I thought we should not leave the super account in each client side.
So I want to know what privileges should be assiged to the account in SQL Server?
Or somewhere already have documents to say how to build up the client account.
thanks.Hi,
