Average HTTP response time going up week by week as said by SAP

Hello All,
I was looking into our SRM earlywatch report,SRM is on windows SQL server 2005 with Windows 2003 server
In the performance indicators,there is an interseting trend though nothing is in yellow or red
The values of following parameters : average response time in HTTP task, the maximum no of HTTP steps per hour and the average DB request time in HTTP task are going up
I understand that as the no of HTTP steps are increasing,the response time is becoming more which is quite obvious.
But how to balance this load out so that the average response time comes down?
what steps should be taken so that I can get this response time to come down though the load on the server is going up
Rohit

Hi Rohit,
Is you system in High Avalibity setup? If yes, then try to load the balance on Node A and Node B. If this is already done or if your system is not in high availability then plan and install a Additional application server (Dialog instance) for load sharing.

Sharath

CCMS Monitoring for Average HTTP response time

Hi guys ,
Is it possible to monitor Av. response time for HTTP(this is based on ST03) using CCMS ?
Thanks in advance
George

hi
As per my understanding you tried to view the responsetime comp as same like in sto3 by ccms, the way as below, RZ20-> SAP CCMS montior templates- >Entiresystem-><sid>->application server -><server>R3 services -> DIalog you can get all the response time as same in the ST03.
else in otherway if you looking for monitoring Java and webdynpro, you can do this by GRMG.chk this for to knw http://help.sap.com/saphelp_nwpi71/helpdata/en/45/4ee37fea5917eae10000000a155369/content.htm|http://help.sap.com/saphelp_nwpi71/helpdata/en/45/4ee37fea5917eae10000000a155369/content.htm]

Average Dialog Response Time.

Hello friends.........
What is the table or function module that stores the data of Average Dialog Response Time (transaction ST03)? After executing ST03, when a particular date is selected, i need the table or function module that stores the value corresponding to Dialog and Time.
Thanks & Regards,
Ajay.

check ST05? i dont have idea on St03.
or STAT .

HTTP response time - From any SAP table.

Hi,
Can we get http response time other than from SMICM u2192 Http log?
Reason for me to ask is we cannot see complete URL in smicm log with response time.
date - "POST /sap/bc/webdynpro/sap/cprojects/?sap-contextid=......................................... HTTP/1.1" 200 325894 9555 h[-]
As per sap help link complete URL after contextID is hidden for security reason.
http://help.sap.com/saphelp_crm70/helpdata/EN/48/442541e0804bb8e10000000a42189b/frameset.htm
u201CFor security reasons the following information is hidden (replaced with points) from the logging procedureu201D
Question: can we access complete URL from any table level with http response time, any input is appreciated.
Thanks,
Venkat.

Michael,
First of all, thanks for the reply.
In our environment we have cprojects implemented and have lot of webdynpro request to ECC system.
From http log (SMICM) I can see many webdynpro requests with response time above 30 minutes; I want to automate this monitoring by writing a CCMS data supplier. We already have SAP document to write data supplier.
Scenario: For example if they are doing a task in cprojects.
We will be having a GET webdynpro request and then POST. By looking at GET we can know the task user is trying to do. But it is POST request which will be taking most of the response time and POST URL is show u2026(point) after context ID and as per SAP help this is done for security reason.
HTTP log from SMICMu2026
[DATE] - "GET /sap/bc/webdynpro/sap/cprojects?sap-client=clnt&STARTVIEW=Tasks&OBJECT_TYPE=TTO&GUID=GUIDNUMBER
[DATE] - "GET /sap/bc/webdynpro/sap/cprojects/~ucfLOADING?sap-contextid=....................
[DATE] - "POST /sap/bc/webdynpro/sap/cprojects/?sap-contextid=........................[response time]
I think SAP is displaying as point in http log file, but it should definitely have complete URL is any of the table.
So I am looking If we can find the complete POST URL with response time from table then we can write an ABAP program to send the information to CCMS.
Thanks,
Venkat.

Average support response time with free support plan

Some time ago I noticed that I have 3 Adobe ID's.
2 of them are correct
2 of them have products registered to them
1 that has a product registered to it is erroneous: has the wrong country in its registration details
I contacted support and was assisted promptly and accurately. I needed to provide a few more details that I had to take a moment to collect. The support agent opened up a support case where I could later place the missing information.
I informed the support agent that I would be away on holiday for a week. And immediately after I added the information that'd come in in the meantime.
This was 1st of may. All has been silent since then.
I tried to open up a chat to ask what the average response times are for free support plan subscribers, but I no longer get access to the chat... I guess I was probably just lucky the first time.
Anybody here know when (on average) I could expect an update to that support case?

Up to 2 weeks and given the current madness after the CS7/ CC announcment possibly longer.

HTTP Response time

Hi
I try to log the response time for my http request
having enabled it with LogResponseTime Property in service HttpProvider (setting it to true)
(using SAP Web AS Java 2004s SPS10)
in the responses.trc file I see the following output (here is an sample)
[Nov 1, 2007 1:49:41 PM ] - 111.111.111.111: POST /webdynpro/dispatcher/sap.com/pb/PageBuilder;jsessionid=..... HTTP/1.1 200 29497 [19140]
Could somebody tell me, which field is related to the reponse time, and which unit is used to measure the time (seconds, milli seconds)...
Any help is appreciated
Regards Karin

Hi Karin,
The time is in milliseconds:
http://help.sap.com/saphelp_nw70/helpdata/en/52/46f6a089754e3a964a5d932eb9db8b/frameset.htm
I believe it is the value in brackets:
[19140] = 19 seconds
Does that correspond with the times you observe?

Average Response Time Different in SLR/EWA (in solman) and ST03 (in satelli

Hi All,
We find that the average dialog response time shown in SLR and EWA reports of Solman is much lower (250 ms) whereas the dialog response time shown in ST03 transaction of the system (XI instance) is high 2000 ms.
Which one is correct and how can I correlate these two values if both are right in their own way.
regards

Hello,
The data source is ST03, therefore unless there is an issue with the collectors, you should assume the ST03 data is correct.
Pleae run RTCCTOOL on the managed system and ensure ST-PI and ST-A/PI are current.. Also make sure your SAPOSCOL is current.
There is a possibility that there was an error during preparing the transport to send the data back to Solution Manager, so scan the SDCCN task logs for any errors/warnings on the managed system. You can also check the transport to see what vaues are being returned to Solman's service session. If the have the same value as ST03 at this point, then there is an issue witht eh EWA/SLR provcessing. If the data is not the same here as ST03 then there was an issue with the SDCCN tasks.
If the data collection is not at issue and the transfering of that data to Solution Manager service session had no errors, then Please follow Jared's recommendation, as this would then be an issue processing the service sessions, and this could be due to outstanding Service Content updates. This can be checked with transaction code AGS_UPDATE.

On average, how many times do you have to restart ...

Ever since I've been using the E71 (less than a month, a new set), I have to restart it about thrice daily. Mostly, the problem occurs while connecting the phone to the PC (Windows 7) when the USB connection type selector on the phone (which appears when you connect the cable and asks for which mode to connect in) freezes; but some other times, just about any application (including the built-in ones) decides to take a nap and the only way to get it back is turn the set off and then back on again. And as soon as that is done, the app icons are all moved back from the customized folders to the folder "Installations" - very frustrating. I'm afraid of restarting this phone as lots of settings and app icons revert back to the defaults after restarting and I've to go through them again. But at the same time, there seems to be no way to make a stuck USB connection type selector work again without restarting.
Well, from my experience here, I know this particular problem has no solution. (Even if the process is ended using an external app manager, it hangs again on starting the app. This continues until the phone is restarted.) Therefore, I'm not looking for a solution here, although one will be welcome if you've undergone the same and have found a workaround. I just wanna know if you do also have to restart your phone. (I also have one Sony Ericsson and an iPhone; I don't generally need to restart them as long as I don't want to restart. At my current place, however, a Nokia phone is all I can use.)
So, do you have to restart your phone when you don't actually want to? If so, on average how many times a day (or a week)? This will help me determine if the problem lies with the phone or it's me who's doing something differently. Is there something you need to do regularly or often (like connecting the phone to the computer) and that operation generally results in a restart of the phone? Thank you for your response.

Yes I have apps installed on the SD card. Shifting them to the internal memory is not really an option (would leave very little free space over there which would then cause other problems). Besides, if the phone allows you to install the apps on the card, shouldn't they work from there? Yes, they should.
Without the card, there will be no custom apps and the phone would be almost useless (will turn into a basic device used to make calls and send text). To me, this is not an option. Also, I don't see how it would solve the problem automagically after some time.
The card doesn't seem to be faulty. I tried to connect the phone without the card inserted and it got connected alright for two times but the USB mode chooser froze the third time, just the same as with the card inserted. So a new card is probably not going to solve the problem.
Must be something strange happening here. Maybe it's due to the apps installed on the card rather than the internal memory, but I just cannot install all those apps within that limited space.
Thanks for the feedback. I'm waiting for more members' experience to come to any conclusion.

ACE 4710: Find out the response time of a real server

Hi to everyone,
I have a couple of ACE 4710 and I need to find out what is the response time of a real server.
Is there a way for this?
Thank you for any answer!

Hi,
Kindly add the following line in your serverfarm configuration:

rserver SC112
inservice
rserver SC113
inservice
rserver SC114
inservice
rserver SC120
inservice
rserver SC131

Configuring the Application Response Predictor
To instruct the ACE to select the server with the lowest average response time for the specified response-time measurement based on the current connection count and server weight (if configured), use the predictor response command in server farm host or redirect configuration mode. This predictor is considered adaptive because the ACE continuously provides feedback to the load-balancing algorithm based on the behavior of the real server.
To select the appropriate server, the ACE measures the absolute response time for each server in the server farm and averages the result over a specified number of samples (if configured). With the default weight connection option configured, the ACE also takes into account the server's average response time and current connection count. This calculation results in a connection distribution that is proportional to the average response time of the server.
The syntax of this command is as follows:
predictor response {app-req-to-resp | syn-to-close | syn-to-synack}[samples number]
The keywords and arguments are as follows:
•app-request-to-resp—Measures the response time from when the ACE sends an HTTP request to a server to the time that the ACE receives a response from the server for that request.
•syn-to-close—Measures the response time from when the ACE sends a TCP SYN to a server to the time that the ACE receives a CLOSE from the server.
•syn-to-synack—Measures the response time from when the ACE sends a TCP SYN to a server to the time that the ACE receives the SYN-ACK from the server.
•samples number—(Optional) Specifies the number of samples over which you want to average the results of the response time measurement. Enter an integer from 1 to 16 in powers of 2. Valid values are 1, 2, 4, 8, and 16. The default is 8.
For example, to configure the response predictor to load balance a request based on the response time from when the ACE sends an HTTP request to a server to when the ACE receives a response back from the server and average the results over four samples, enter:
host1/Admin(config)# serverfarm SFARM1
host1/Admin(config-sfarm-host)# predictor response app-req-to-resp
samples 4
To reset the predictor method to the default of round-robin, enter:
host1/Admin(config-sfarm-host)# no predictor
To configure an additional parameter to take into account the current connection count of the servers in a server farm, use the weight connection command in server farm host predictor configuration mode. By default, this command is enabled. The syntax of this command is as follows:
weight connection
For example, enter:
host1/Admin(config)# serverfarm SF1
host1/Admin(config-sfarm-host)# predictor response app-request-to-resp
samples 4
host1/Admin(config-sfarm-host-predictor)# weight connection
To remove the current connection count from the calculation of the average server response time, enter:
host1/Admin(config-sfarm-host-predictor)# no weight connection
You can use threshold milliseconds parameter which is optional Specifies the required minimum average response time for a server. If the server response time is greater than the specified threshold value, the ACE removes the server from the load-balancing decision process (takes the server out of service).
Enter an integer from 1 to 300000 milliseconds (5 minutes). The default is no threshold (servers are not taken out of service).
In case if you have measures the response time from when the ACE sends a TCP SYN to a server to the time that the ACE receives a CLOSE from the server use syn-to-close      (already discussed previously)
If you have to measures the response time from when the ACE sends a TCP SYN to a server to the time that the ACE receives the SYN-ACK from the server use syn-to-synack   (already discussed previously)
SAMPLES parameter is optional and specifies the number of samples that you want to average from the results of the response time measurement and response time is used to select the server with the lowest response time for the requested response-time measurement. If you do not specify a response-time measurement method, the ACE uses the HTTP app-req-to-response method.
Whenever a server's load reaches zero, by default, the ACE uses the autoadjust feature to assign a maximum load value of 16000 to that server to prevent it from being flooded with new incoming connections. The ACE periodically adjusts this load value based on feedback from the server's SNMP probe and other configured options.
Using the least-loaded predictor with the configured server weight and the current connection count option enabled, the ACE calculates the final load of a real server as follows:
final load = weighted load Ã— static weight Ã— current connection count
where:
â€¢weighted load is the load reported by the SNMP probe
â€¢static weight is the configured weight of the real server
â€¢current connection count is the total number of active connections to the real server
The ACE recalculates the final load whenever the connection count changes, provided that the (config-sfarm-host-predictor) weight connection command is configured. If the (config-sfarm-host-predictor) weight connection command is not configured, the ACE updates the final load when the next load update arrives from the SNMP probe.
If two servers have the same lowest load (either zero or nonzero), the ACE load balances the connections between the two servers in a round-robin manner.

High Dialog response time

Hi,
We have a solman 4.0 system. The average dialog response time of the system is very high. What can be done to bring down this response time??
Thanks in Advance

Hi Amit,
Please check out the breakdown of dialog response time in Workload Monitor. Also, use the Time Profile to check if this high response time is at specific timings.

High GUI Time - Causing high Response time

Hi All,
Average GUI Response time is approx 400 ms in my ECC 6.0 system, OS - HP UX, Database - Oracle 10.2.0.5.
I expect it should always be approx 200 ms, but as it is high it is contibuting to high overall response time.
I expect there are normally two ways of high GUI time :
1) High network time between Presentation layer( User System) and Application Layer(SAP Server).
2) High amount of time in Loading User Screen
For Option 2 I have checked we are using SAP access menu so there should not any problem with loading of User Access Menu.
Average Response time for session_manager is 2 Secs.
Please suggest me what all other ways available to improve GUI time,
Can there be other reasons of high GUI time and how can we make sure that high GUI time is only because of high Network time.
Please suggest.
Shivam

I believe in case you have multiple roundtrips per step, then the client performance comes into play as well. So if you have slow clients this could be an issue too.
Basically you are already looking in the right place (network connection), but i recommend you also check:
- roundtrips per step and amount of data sent to the client
- are all transactions having high gui times, or only a few?
- how is the situation on the clients?
- if you have clients working on prod and qas check the values on the qas system too
Cheers Michael

High CPU response times, altough low CPU utilization

Hi Friends,
We have a performance problem after we migrate our basis system,
The current system is :
Database server : Sun SPARC Enterprise T5240 Server - 2 CPU's with 6 core, 8 thread, 1.2 Ghz
32 GB RAM
and we use another identical configured server as an application server.
Database is Oracle 10.2.0 and operating system is Solaris 10.
The problem is average CPU response time is 450 ms, and max. CPU load is %5 percent.
Pre-migration configuration with old servers, we had CPU response : 150 ms and max CPU load: 50%.
Has anyone of you, have experinced a similar problem with this new CPU's?
Thanks in advance

> I am aware that there might be lots of reasons, but what I guess is, there should be a parameter wrong with the CPU settings. This SPARC server CPU is a new tech. 6 core 8 thread one, which is expected to work much faster than the old simple dual core CPU.
Is it?
ABAP is basically a virtual machine and what is most important: ABAP runs single threaded. This means in consequence that the processing time of a program relies on the single processing power of one core. More cores means more parallelism but the speed of the single statement always relies on the power of one core and how fast it can get the data over the bus and back. So the significant number for speed is basically the Mhz (for ABAP, Java is very different).
Your old machine may have had a DualCore SPARC 1,2 Ghz and the new machine has one 1,4 Ghz 6core CPU (assuming so).
> However its response time is very high, although it is never utilized more than %5 percent.
see above.
> The problem might be at database settings(Oracle 10.2.0) or at Solaris ? ? ?
Well - no - I don't think so
Since ABAP is a single threaded application it can't leverage the CPU power due to the fact, that a parallelism in the program itself does not take place and hence the machine scales not linear with the number of cores. So you may have factually a machine with about 1 dot something CPUs and not 6 as you would expect.
This is not specific to SPARC CPU design but for all multi-core systems. A single threaded application is only as fast as the CPU speed. ABAP programs tend to be huge so you will also see effects of cache displacement and bus congestions. Less cores and more physical CPUs perform much better than any multicore CPU.
For Java the world is very different because Java works as one process (in the SAP case jlaunch) which has many many threads that can be executed in parallel on different pipelines on the CPU.
Unfortunately this is a design problem and there's not much you can do about it.

How to get query response time from ST03 via a script ?

Hello People,
I am trying to get average query response time for BW queries with a script (for monitoring/historisation).
I know that this data can be found manually in ST03n in the "BI workload'.
However, I don't know how to get this stat from a script.
My idea is to run a SQL query to get this information, here is the state of my query :
select count(*) from sapbw.rsddstat_olap
where calday = 20140401
and (eventid = 3100 or eventid = 3010)
and steptp = 'BEX3'
The problem is that this query is not returning the same number of navigations as the number shown in ST03n.
Can you help me to set the correct filters to get the same number of navigation as in ST03n ?
Regards.

Hi Experts,
Do you have ideas for this SQL query ?
Regards.

CPU bits and Moniter response times

Do the G5 iMacs have a 32 bit CPU or 64 bit?
What is the response time for the monitors on the G5s?
Answers would be great! Thank you.
super duper di duper scooper pooper in your face Windows XP

Welcome to the discussions!
All G5s are full 64-bit CPUs.
As far as pixel response time goes, that is not something that Apple has ever published, but AFAIK the iMacs use the same LG.Philips LM201W01 panel as the 20" Cinema display. Depending on who you believe, that panel has either a 16 or 12 ms response time.
Apple uses S-IPS panels for their superior color matching capabilities due to the fact that so many people in creative careers use Macs. Response time is not as important as color accuracy.
The TN panels used by many manufacturers have a much better response time and contrast ratio, but are clearly not as good as S-IPS for color.
