ST03 statistics details :- Response time distribution
Hi Experts,
We have requirement to display the Percentage (cumulated) of response time distribution view of ST03 transaction code.
There is one standard infocube 0CCMSATTI.
Can anybody pls explain about the significance of fields like CNT01 to CNT09 of 0CCMSATTI infocube?
Thanks
Kind Regards
Anukul
hi,
the definition of the infoobjects are stored in strucutre SAPWLTSK.
CNT001 -- SAP Workload: Number of Steps with Response Time < 0.1s
CNT002 -- SAP Workload: No. of Steps with Response Time 0.1s< RT< 0.2s
CNT003 -- SAP Workload: No. of Steps with Response Time 0.2s< RT< 0.3s
CNT004 -- SAP Workload: No. of Steps with Response Time 0.3s< RT< 0.4s
CNT005 -- SAP Workload: No. of Steps with Response Time 0.4s< RT< 0.5s
CNT006 -- SAP Workload: No. of Steps with Response Time 0.5s< RT< 1.0s
CNT007 -- SAP Workload: No. of Steps with Response Time 1s< RT< 2s
CNT008 -- SAP Workload: No. of Steps with Response Time 2s< RT< 3s
CNT009 -- SAP Workload: No. of Steps with Response Time 3s< RT< 10s

Any way to get more statistics and response-time info from cache processes?
I'm currently involved in an evaluation of Coherence for use as a global in-core cache/DB for data in the GB range. We'll try to run multiple cache process per cache in order to stay below 512MB heap-space per cache process.
In order to tune cache access times and understand the dynamic behaviour of the app we'd like to see some statistics info for cache access, e. g.
- requests processed per cache (process)
- requests answer time (per request, min, max, avg, median etc.)
- request answer size (number of cache entries returned, size of entries etc.)
- whatever else that helps ...
We are in position to get this kind of statistics info on the application side (when we call Coherence-APIs) but we'd need to see the statistics on a technical level per cache process.
We know about JMX/MBeans but that does not allow us to come up with log-files for statistical analysis and there is no way to correlate requests from the application to any statistics information (what request did cause what effect).
Any way to tell the cache processes to provide this kind of (logging) info (mesurements per request) and some summary.David,
In addition to statistics that you can collect at the client tier (measuring the latency of individual cache calls), you could use a number of attributes exposed by the ServiceMBean.
If you look at a ServiceMBean for your partitioned cache service, the RequestAverageDuration and RequestMaxDuration attributes describe the latency of the underlying communication tier as seen from the client and does not include the serialization/deseriation cost.
The TaskAverageDuration, TaskMaxBacklog and ThreadAverageActiveCount expose the latency and expenses as seen by the server side, excluding the network tier expenses.
Also, there are number of statistics exposed by the CacheMBean related to the underlying backing map efficiency such as AverageGetMillis, AverageHitMillis, AverageMissMillis and AveragePutMillis.
You can also create your own subclasses for backing map implementation and implement custom MBeans that would expose any addition information you wish to collect.

Query Tuning - Response time Statistics collection
Our Application is Load tested for a period of 1 hour with peak load.
For this specific period of time, say thousands of queries gets executed in the database,
What we need is say for one particular query " select XYZ from ABC" within this span of 1 hour, we need statistics like
Number of times Executed
Average Response time
Maximum response time
minimum response time
90th percentile response time ( sorted in ascending order, 90th percentile guy)
All these statistics are possible if i can get all the response times for that particular query for that period of 1 hour....
I tried using sql trace and TKPROF but unable to get all these statistics...
Application uses connection pooling, so connections are taken as and when needed...
Any thoughts on this?
Appreciate your help.I don't think v$sqlarea can help me out with the exact stats i needed, but certainly it has lot of other stats to take. B/w there is no dictionary view called v$sqlstats.
There are other applications which share the same database where i am trying to capture for my application, so flushing cache which currently has 30K rows is not feasible solution.
Any more thoughts on this? -
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.
regardsHello,
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.

Table name for dialog response time without GUI in ST03?
In SWNC_COLLECTOR_GET_AGGREGATES, cnt00x (x =1,2,3... 9) gives me the proportion of transaction steps with a response time between 0s and the upper limit of the individual response time categories (includes GUI time), broken down by task type. But where is the data without GUI time store? any ideas?
Hello Surya
here screenshots from my test:
ST03 for my instance before I have executed something on it, no dialog task type:
here I have connected to the instance through SM51, still no dialog task type:
and here I have connected directly through SAP Logon to this instance, now my actions on the instance are displayed as dialog task type:
If your users connect through RFC to the instance, then all their actions are RFC task type actions. As soon as a user logons directly to the instance, dialog task type will appear in ST03.

Report to calculate avg response time for a transaction using ST03.
Hi Abap Gurus ,
I want to develop a report which calculates the average response time(ST 03) for a transaction on hourly basis.
I have read many threads like in which users are posting which tables/FM to use to extract data such as dialog step and total response time .
I am sure many would have created a report like this , would appeciate if you can share pseudo code for same.Any help regarding the same is highly appreciated...

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 ?

How to Tune the Transactions/ Z - reports /Progr..of High response time
Dear friends,
in <b>ST03</b> work load anlysis menu.... there are some z-reports, transactions, and some programmes are noticed contineously that they are taking the <b>max. response time</b> (and mostly >90%of time is DB Time ).
how to tune the above situation ??
Thank u.Siva,
You can start with some thing like:
ST04 -> Detail Analysis -> SQL Request (look at top disk reads and buffer get SQL statements)
For the top SQL statements identified you'd want to look at the explain plan to determine if the SQL statements is:
1) inefficient
2) are your DB stats up to date on the tables (note up to date stats does not always means they are the best)
3) if there are better indexes available, if not would a more suitable index help?
4) if there are many slow disk reads, is there an I/O issue?
etc...
While you're in ST04 make sure your buffers are sized adequately.
Also make sure your Oracle parameters are set according to this OSS note.

High RFC response time in SAP BW system
Hello all,
How to analyze and fine tune high RFC response time in SAP BW system ?
Regards,
ArchanaHi
Kindly Check follows
1. Check the RFC connections are correctly Configured or not? You can execute the program “RSRFCTRC” and get a full log of the RFC connections details
2 you can check the BW queries are right optimized? Is this any network issues?
3. In which time are you facing the high rfc response? (During the 24 hours which time)?
4. Kindly refer the SCN & SAP Notes for overall system performance

Everything that comes inside the "select * from(...) view" parentheses is defined in a view. We've noticed that the line "AND d.payed = 'N'" (commented above) is the guilty clause: the query takes one or two seconds to return between 400 and 500 rows if this line is removed, when included in the query, the response time then switches to *hours* -sic !- but then the result set is empty (no rows returned). The plan is exactly the same whether this "d.payed = 'N'" is added or removed, I mean the nb of steps, access paths, join order etc., only the rows/bytes/cost columns values change, as you can see.
We've found no other way of solving this perf issue but by taking out this "d.payed = 'N'" condition and setting it outside the view along with view.DISTRIB_CODE and view.TIME_OPERATION.
But we would like to understand why such a small change on the XYZ.PAYED column turns everything upside down that much, and we'd like to be able to tell the optimizer to perform this check on payed = 'N' by itself in the end, just like we did, through the use of a hint if possible...
Anybody ever encountered such a behaviour before ? Do you have any advice regarding the use of a hint to reach the same response time as that we've got by setting the payed = N condition outside of the view definition ??
Thanks a lot in advance.
Regards,
SebI am really sorry I couldn't get back earlier to this forum...
Thanks to you all for your answers.
First I'd just like to correct a small mistake I made, when writing
"the query takes one or two seconds": I meant one or 2 *minutes*. Sorry.

Yes but it only shows more of *everything* (more tables blocks accessed, the same
for indexes blocks, for almost all objects involved) for the slowest query !
Greping WAIT on the two trc files made for every statement and counting the
object IDs access show that the quicker query requires much less I/Os; the
slowest one overall needs much more blocks to be read (except for the indexes
DNSG_NI1 or DNPE_XYZ for example). Below I replaced obj# with the table/index
name, the first column is the figure showing how many times the object was
accessed in the 10053 file (I ctrl-C'ed my second execution ofr course, the
figures should be much higher !!):

Weekly response time of workproces
hi
1.how to check weekly response time of a particular work process?
2. does abap program which is usually developed by our abapers is client specific or cross client?Hi Ramesh,
ABAP programs are cross client. They are repository objects!!!.
Dont know if it is possible to check repsonse time of a process as such. Yes you can do an performance analysis of dialog/background,update WPs etc. as a bunch but individual process analysis in terms of weekly data.. I have no idea. Anyways it makes sense to do this analysis for type of workprocess and not a workprocess in itself. It is not as if a workprocess is performing well you are going to replace it with something new :-). For system performance analysis ST02,ST03,ST03N,ST04 and ST06 are best transactions though check ST03 and ST03N in your case of process response time analysis. May be you will find historical details of an individual work process using ST03N. Wish u luck.
Please award points for useful info.
Regards.

ST03N Tcode not showing last 3 days average response time
Hi,
In my Production system not showing last 3 days average response time.In our production 1 (CI+DB) and 3 dialog instances are there. In all servers sapcollector working fine but in all servers not showing last 3 days values.Please advise solution.
Thanks,
Srinivas.The following are the prerequisites needed to get the workload monitor(st03) working.
1) The system time zone of the SAP and the Operating system has to be same. This can be done by customizing time zones of the SAP using the Tcode STZAC.
2) All the standard background jobs has to be scheduled to run. This can be done by scheduling the standard background jobs using the Tcode SM36.
3) The following parameters has to be added to the instance profile.
Parameter Value(default) Description
i. stat/as_collect = 2 Application statistic: detailed records.
ii. stat/as_level = 1 Records for application statistic are active.
iii. stat/max_files = 48 Max. no. of stat files to be kept.
iv. stat/as_max_files = 48 Max. no. of appl. stat files to be kept.
This can be done by editing the profiles using the Tcode RZ10. -
How to get Query response Time?
II am on BI 7.0. I ran some queries using RSRT command. I want to find how much time the queries took.
I went to
st03 -> expert mode -> BI system load-> select today / week/month according to the query runtime day
I do not see any Info Providers. Query was on a cube so why no Info Providers.
Does something have to turned on InfoPorvider to show.
When I look in RSDDSTAT_OLAP table, I do see many rows but cannot make any sense. Is there some documentation on how to get total query time from this table?
Is there any other way to get query response time?
Thanks a lot.HI,
why not use RSRT ? You can add database statistics option in "Execut & Debug" and you get all the runtime metrics of your query
In transaction RSRT, enter the query name and press u2018Execute +Debugu2019.
Selecting u2018Display Statistics Datau2019 .
After executing the query will return a list of the measured metrics.
The event id / text describes the steps (duration in seconds):
"OLAP: Read data" gives the SQL statements repsonse time (ok - because the SAP
application server acts as an Oracle client a little network traffic from the db server is included,
but as far as you not transferring zillions of rows it can be ignored)
But it gives you much more (i.e. if the OLAP cache gets used or not )...
In the "Aggreagate statistcs" you get all the infoproviders involved in that query.
bye
yk
