Transaction response time increase all of suddden
We are in peculiar situation in the oltp env of 11g.
oltp normal transaction will be completed in less than 1 second, sometime its goes up 6 seconds. we looked in awr report and in os load, there are no spikes and they are normal as previous. Application team is blame us, its problem with database. App server i.eApache configured with connection pool so i can't able do the sql trace. How to diagnose this situation? Through ash/awr report can we find any symptons. please advise..

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.

Dear all,
While performing the Load test, during initial 2 - 3 hrs performance is very good. after 2 -3 hrs response time increasing and there by throughput going down 4 times.
when i check in GC Log, i found all OC's. generally i used to find many YC's and very less OC's. but this time its deferent. not sure why this behaviour.
Below is snap shot of my gc.log.
Following are my startManagedweblogic java options.
JAVA_OPTIONS="${JAVA_OPTIONS} -Xverbose:memory -Xmx:6144m -Xms:6144m -Xns:3072m -Xverbosetimestamp -Xgcprio:pausetime -Xverboselog:/usr/home/WEBADM/blq2gsbl/BLQRYSBDM/bin/gc.log -Xverbose:gcreport -XlargePages -XXgcThreads:8 -XXtlasize:min=2k,preferred=16k -XXnoSystemGC"
please note that i have enough memory to increase till 12 gb also. i found better performance with 6g so i kept it as 6.

(run a test using test console and you would get that)
In error handler of stage from where you are calling this business service, check whether status code in $fault is equal to the error code due to response timeout. If it is equal then replace content of $body with required error xml and use reply with success.
See section "37.6 Fault Variable" to know more about $fault -

How to capture transaction response time in SQL
I need to capture Transaction response time (i.e. ping test) to calculated the peak hours and averaged
on a daily basis.
and
Page refresh time that is calculated no less than every 2 hours for peak hours and averaged on a daily basis.
Please assist
kMy best guess as to what you are looking for is something like the following (C#):
private int? Ping()
System.Data.SqlClient.SqlConnection objConnection;
System.Data.SqlClient.SqlCommand objCommand;
System.Data.SqlClient.SqlParameter objParameter;
System.Diagnostics.Stopwatch objStopWatch = new System.Diagnostics.Stopwatch();
DateTime objStartTime, objEndTime, objServerTime;
int intToServer, intFromServer;
int? intResult = null;
objConnection = new System.Data.SqlClient.SqlConnection("Data Source=myserver;Initial Catalog=master;Integrated Security=True;Connect Timeout=3;Network Library=dbmssocn;");
using (objConnection)
objConnection.Open();
using (objCommand = new System.Data.SqlClient.SqlCommand())
objCommand.Connection = objConnection;
objCommand.CommandType = CommandType.Text;
objCommand.CommandText = @"select @ServerTime = sysdatetime()";
objParameter = new System.Data.SqlClient.SqlParameter("@ServerTime", SqlDbType.DateTime2, 7);
objParameter.Direction = ParameterDirection.Output;
objCommand.Parameters.Add(objParameter);
objStopWatch.Start();
objStartTime = DateTime.Now;
objCommand.ExecuteNonQuery();
objEndTime = DateTime.Now;
objStopWatch.Stop();
objServerTime = DateTime.Parse(objCommand.Parameters["@ServerTime"].Value.ToString());
intToServer = objServerTime.Subtract(objStartTime).Milliseconds;
intFromServer = objEndTime.Subtract(objServerTime).Milliseconds;
intResult = (int?)objStopWatch.ElapsedMilliseconds;
System.Diagnostics.Debug.Print(string.Format("Milliseconds from client to server {0}, milliseconds from server back to client {1}, and milliseconds round trip {2}.", intToServer, intFromServer, intResult));
return intResult;
Now, while the round trip measurement is fairly accurate give or take 100ms, any measurement of latency to and from SQL Server is going to be subject to the accuracy of the time synchronization of the client and server. If the server's and client's
time isn't synchronized precisely then you will get odd results in the variables intToServer and intFromServer.
Since the round trip result of the test is measured entirely on the client that value isn't subject to the whims of client/server time synchronization. -
Reporting transaction response time
Hi all,
does anybody knows a possibility to monitor the responsetime for a
special transaction ( e.g. CIC0 ) ?
Best regards
Andreas LaaserHi 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.

Dramatically increased response times when connected to network
I suddenly noticed that the response time for opening a folder item in my local Portal installation increased when I connected to the network. Why? I want to understand this, since I'm supposed to help a customer with their performance problems.
Further details:
The response time increased from about 2 seconds to about 10 seconds when I connected to the network. In this case, I connected via an ISDN line to my normal dial-up number at work. However, when I connect to my private ISP account (Telenor Online), the response times are unchanged, i.e. still 2 seconds.
One difference between the two access points is the use of a proxy in the first case.
What's the explanation?
Thanks, Erik Hagen

RFC response times deteriorate with time
Hi
We notice that every time our system is restarted, performance is much improved for a the first few weeks. I can appreciate this from the fact that it is a huge system and things can 'clog up' after a while but we have been trying to isolate any specific cause / memory leaks etc.
One thing we have noticed is that although average dialog and background response times appear to increase gradually with time, RFC response times increase substantially. The first few days after a restart we see times of 2, 3 seconds, by the first week 7-10 seconds and by week two and beyond they are over 20 seconds.
We have 15 application servers and all the RFC traffic is load balanced using a RZ12 group that does not include the Central Instance; the same applies in SMQR & SMQS. We still do see some RFC traffic on the CI though... some of the application servers are on a different site, but we cannot see any differences in response times across sites...
Any ideas what's causing this and how we can keep these RFC response times down? The system is very busy and deals with a lot of RFC traffic, when users start complaining about poor performance we can usually see the system flooded with RFCs....
Due to size and nature of this system we can only arrange a restart every couple of months.
Thanks
RossHi Markus, good question, but no, haven't noticed... not sure how I'd check either? There are hundreds (if not thousands) of different transactions ran each month, I'll try sorting the transactions by time for each day and see if there are any common longer runners that have increased, but think it'll be like looking for a needle in a haystack...

Slow response time for JSP pages under iAS 6.0 SP4
Hi,
I got an application deployed on iplanet app server 6.0 SP4 on solaris
2.8. Using a single kjs engine and lite sessions. kjs memory size is
min 256 and max 256 megs. but verbose:gc shows memory is 98% free.
when i restart the app server, all JSP pages are really rendered fast.
After a while (1 or 2 days), the time to service the same request to
JSP pages is getting much longer (even with JSP pages having only
static content in them). CPU is idle ... It just takes time. KXS log
shows requet is taking like 2-4 seconds instead of about 150 milli
secs when the engine is just restarted.
Now if i call a servlet (which do not dispath to a JSP), the response
time is ok! Memory is ok. It looks like its related to JSP pages
only.
Anyone having an idea what the problem could be? One conig param is
the JSP page cache in iASAT. Default value is 10. What is a correct
setting for production? I have 4 different web app deployed in the
same server instance.
Tanks a lot for your input
Andre ParadisAndre,
I have found the answer to my problem and perhaps yours. It seems that I18N (internationalization) in SP4 may have a performance bug in it.
My soak tests show that with i18N checked in the iAS Admin Tool, testing the fortune cookie sample application with light load (1 request / sec) resulted in a kxs response time initially of 15ms, however this response time increased by roughly 1% per request (i.e after 100 requests the response time had more than doubled).
Switching I18N off yielded a steady 7ms kxs response time from the fortune cookie application.
I would add that I turned I18N on AFTER the installation procedure.
Is this a known issue in SP4? Is there a patch?
regards,

Hi all,
I have just configured ACE 4720 and started heavy test from a single source host to the group of http servers. All works fine and mean response time during all test is good (about 0.2 sec) but max response time grows from about 0.4 sec. to the 3 sec. after 30 sec the test starts and sometimes up to the 6 or 9 sec. How do I fix this?Try to check "sh resource usage all" to see if there is "Denied" count incrementing. It could be resource issue.

Management Services Response Time; per Role or per Deployment? Broken?
Management Services, Alert on Response Time, appears to be incorrect.
Can you help me understand why the Response Time charts for each Role in a deployment are identical? is this a bug?
My Testing
I have 3 Roles in my Cloud Service Deployment. A Web Role, a worker Role, and an extra Worker Role for this test.
Web Role: Light load 0 to 10 requests per hour.
Worker Role: Generates massive net work traffic. Constantly making web service calls to 3rd party data services & running a Distributed Azure Data Cache.
Extra Worker Role: No load. I added it to test this problem. It does nothing other than respond to Management Services Alert pings.
I created 3 Alerts to Track response time. One to each of the 3 roles, testing from within the same data center; San Jose to San Jose. Then added 3 more to test from Singapore to San Jose.
The Result (over several Months)
A. The San Jose charts are identical for each role.
B. The Singapore charts are identical for each role.
C. The set of Singapore charts are very similar to the San Jose set of charts. With slight variations likely due to internet latency & extra load at Singapore.
D. (most Important). The latency is directly correlated to the network load created by the Worker Role. When I turn it off or throttle it, Response Time on all boxes drops. When working at "full speed" network response time rises
to 10 - 30 secs. (very bad)
Conclusion
The Network Monitoring Response Time Alert is not working as designed. It does not show the Response Time for that Role. But seems to be displaying the Response Time for the whole deployment.
My Request
Can you assist me to understand if this is "By Design". If my testing is flawed? or what is going on.
My Goal
Alert the Azure dev team to this so that maybe they can fix it to function as I expected it to. (or for them to explain why my expectations are unreasonable.)
Why is this important?
Poor Network Perf is a showstopper bug that is preventing us from moving into production. I may be able to solve this with multiple instances. But as I lack the granularity to track even at the Role level. I'm stuck.Thank you for your reply.
I forgot to update this with the answer.
It turned out that Azure Portal's Create Alert/monitoring UI has a bug.
The monitoring service is only capable of pining your public endpoints. ie: your Web Roles. Yet it lets you think you can create an Alert to monitor any of the roles within your solution. To make things worse, it shows a chart that suggests it actually is
pinging your worker roles, when it is actually only pinging the public Web Role.
That is why all the Roles in your solution display identical metrics regardless of their load. Even stopping your worker roles will not affect their ping response times.
If your worker role fails, Azure Alerts don't tell you about it.
NB: Using Application Insights to create alerting does not have this issue. But only because it doesn't attempt to monitor your web roles, not because it can alert you to any issues. -
How to find the Response time for a particular Transaction
Hello Experts,
Am implementing a BAdI to achieve some customer enhancement for XD01 Transaction . I need to confirm to customer that after the implementation and before implementation what is the response time of the system
Response time BEFORE BAdI Implementation
Response time AFTER BAdI Implementation
Where can i get this.
Help me in this regard
Best Regards
SRiNiHello,
Within STAD, enter the time range that the user was executing the transaction within as well as the user name. The time field indicates the time when the transaction would have ended. STAD adds some extra time on using your time interval. Depending on how long the transaction ran, you can set the length you want it to display. This means that if it is set to 10, STAD will display statistical records from transactions that ended within that 10 minute period.
The selection screen also gives you a few options for display mode.
- Show all statistic records, sorted by star
This shows you all of the transaction steps, but they are not grouped in any way.
-Show all records, grouped by business transaction
This shows the transaction steps grouped by transaction ID (shown in the record as Trans. ID). The times are not cumulative. They are the times for each individual step.
-Show Business Transaction Tots
This shows the transaction steps grouped by transaction ID. However, instead of just listing them you can drill from the top level down. The top level will show you the overall response time, and as you drill down, you can get to the overall response time.
Note that you also need to add the user into the selection criteria. Everything else you can leave alone in this case.
Once you have the records displayed, you can double click them to get a detailed record. This will show you the following:
- Breakdown of response time (wait for work process, processing time, load time, generating time, roll time, DB time, enqueue time). This makes STAD a great place to start for performance analysis as you will then know whether you will need to look at SQL, processing, or any other component of response time first.
- Stats on the data selected within the execution
- Memory utilization of the transaction
- RFCs executed (including the calling time and remote execution time - very useful with performance analysis of interfaces)
- Much more.
As this chain of comments has previously indicated, you are best off using STAD if you want an accurate indication of response time. The ST12 (combines SE30 ABAP trace and ST05 SQL trace) trace times are less accurate that the values you get from ST12. I am not discounting the value of ST12 by any means. This is a very powerful tool to help you tune your transactions.
I hope this information is helpful!

Coherence and EclipseLink - JTA Transaction Manager - slow response times
A colleague and I are updating a transactional web service to use Coherence as an underlying L2 cache. The application has the following characteristics:
Java 1.7
Using Spring Framework 4.0.5
EclipseLink 12.1.2
TopLink grid 12.1.2
Coherence 12.1.2
javax.persistence 12.1.2
The application is split, with a GAR in a WebLogic environment and the actual web service application deployed into IBM WebSphere 8.5.
When we execute a GET from the server for a decently sized piece of data, the response time is roughly 20-25 seconds. From looking into DynaTrace, it appears that we're hitting a brick wall at the "calculateChanges" method within EclipseLink. Looking further, we appear to be having issues with the transaction manager but we're not sure what. If we have a local resource transaction manager, the response time is roughly 500 milliseconds for the exact same request. When the JTA transaction manager is involved, it's 20-25 seconds.
Is there a recommendation on how to configure the transaction manager when incorporating Coherence into a web service application of this type?Hi Volker/Markus,
Thanks a lot for the response.
Yeah Volker, you are absolutely right. the 10-12 seconds happens when we have not used the transaction for several minutes...Looks like the transactions are moved away from the SAP buffer or something, in a very short time.
and yes, the ABAP WP's are running in Pool 2 (*BASE) and the the JAVA server, I have set up in another memory pool of 7 GB's.
I would say the performance of the JAVA part is much better than the ABAP part.
Should I just remove the ABAP part of the SOLMAN from memory pool 2 and assign the JAVA/ABAP a separate huge memory pool of say like 12-13 GB's.
Will that likely to improve my performance??
No, I have not deactivated RSDB_TDB in TCOLL from daily twice to weekly once on all systems on this box. It is running daily twice right now.
Should I change it to weekly once on all the systems on this box? How is that going to help me?? The only thinng I can think of is that it will save me some CPU utilization, as considerable CPU resources are needed for this program to run.
But my CPU utilization is anyway only like 30 % average. Its a i570 hardware and right now running 5 CPU's.
So you still think I should deactivate this job from daily twice to weekly once on all systems on this box??
Markus, Did you open up any messages with SAP on this issue.?
I remember working on the 3.2 version of soultion manager on change management and the response times very much better than this as compared to 4.0.
Let me know guys and once again..thanks a lot for your help and valuable input.

Increase synchronous process response time
hi all
From my sycn BPEL process I am calling CRM sycn’ly .
Response from CRM is coming very lately for that I am getting time out error .
Can we achieve a scenario where my sync BPEL process will wait for a longer time .
Its not possible to make it async delayed response also.
Keeping it Sync only how can I increase in response time period?
i am using SOA 10.1.3.4 version.
thx in advance ..Go to the BPEL Properties in EM, then advanced BPEL properties, find the property syncMaxWaitTime And increase it to 240 may be...
Also increase the JTA timeout in weblogic console....keep this value more than 240 -
SBWP transaction - viewing folders/sending documents Long response times
Hi all,
I have some complains from some users (about 3-4 out of ~3000 user in my ECC 6.0 system) within my company about their response times on the Business Workplace. In particulat they started complaining about the response time of calling the TCOD SBWP . For 1-2 of them up to 4-5 minutes when myself as well as my other 2 colleagues were getting response of 500ms.
Then they wanted also to view some folders on the Workplace and they had also response times of minutes instead of seconds.
I checked that some of their shared folders as well as the Trash Bin had thousands of PDFs. I told to delete them and they deleted most of them. Stil when they want to open a folder it takes >2 minutes while for me to open the same shared folder takes 1-2 seconds.
I checked in ST03N (user profiles, single records) and 1 of them had long database calls and request time in the Analysis of ABAP/4 database requests (Single Statistical Records).
I am running out of ideas as I cannot explain why only for those 2-3 users happens to have long response times.
Is it related to their folders in the Workplace? Where should I focus my investigation for the SBWP like transactions? Is it the case that some Oracle parameters might need to be checked?

Your message is not well formatted so you are making it harder for people to read. However your problem is that you have 3-4 users of SBWP with slow runtimes when accessing folders. Correct ?
You mentioned that there is a large number of documents in the users folders so usually these type of problems are caused by a large number of table joins on the SAPoffice tables specific to your users.
Firstly please refer to SAP Note 988057 Reorganization - Information.
To help with this issue you can use report RSBCS_REORG in SE38 to remove any deleted documents from the SAPoffice folders. This should speed up the access to your users documents in folders as it removes unnecessary documents from the SAPoffice tables.
If your users do not show a significant speed up of access to their SAPoffice folders please refer to SAP Note 904711 - SAPoffice: Where are documents physically stored and verify that your statistics and indexes mentioned in this note are up to date.
If neither of these help with the issue you can trace these users in ST12 and find out which table is cauing the longest runtime and see if there is a solution to either reduce this table or improve the access method on the DB level.
Hope this helps

Reg Increasing the EJB Response Time
We are facing below performance problems in our application,
1. Response time from EJB (Stateless Session Bean) to Client (Swing).
2. Time taken for looping through the Result Set.
For 5000 records, our query is taking 0.2 Secs but looping through the ResultSet is taking around 16 seconds and Response time for transferring 160 kb (object data) from EJB to Client is taking around 30 Secs.
We have achieved some improvement in ResultSet looping time by setting the setFetchSize of ResultSet to 250.
Can anyone suggest?
1. Is there any way to increase the Data Transfer time (Response time) from EJB to Client?
2. What is the ideal value for setting the value for ResultSet.setFetchSize() ( No of records we fetch vary from 1 � 3,00,000 records)1. Response time from EJB (Stateless Session Bean) to
Client (Swing). Consider non-EJB options. They might prove efficient in your case.
2. Time taken for looping through the Result Set. Try and design your code as to not require all the records at a time.
For 5000 records, our query is taking 0.2 Secs but
looping through the ResultSet is taking around 16
seconds and Response time for transferring 160 kb
(object data) from EJB to Client is taking around 30
Secs.
We have achieved some improvement in ResultSet
looping time by setting the setFetchSize of ResultSet
to 250. There is a limit to what you can achieve with that.
Can anyone suggest?
1. Is there any way to increase the Data Transfer
time (Response time) from EJB to Client? I suppose you would want to reduce the response time.
2. What is the ideal value for setting the value for
ResultSet.setFetchSize() ( No of records we fetch
vary from 1 � 3,00,000 records)
