Local Client Copy taking too much time

Hi All,
I recently done a system refresh of my Quality server (restore PRD backup to QUA Server)
After that I have created a new client and has initiated a local client copy after the test run
went successful.
Then after reading approximately 4500 table it has got stuck and I saw in SM50 that table "ACCTCR"
was running since approximately 56000 seconds.
Then I run the program 'BTCTRNS1" to clean the work processes.
After that I again restarted the local client copy in restart mode.
Now since last 3 hours I can see in SM50 that table u201CACCTCR" is being sequentially ready for approx 500(under Actions) seconds and then delete for 15 seconds (under actions).
I also found that table size is also not increasing as well as same table is being sequentially read for 500 sec and then deleted for 15 seconds (under Actions in sm50) and program is also same.
This is happening since last 3 hours now.
Under SCC3 I can see the status as processing reset.
Does anyone face this issue ever? And can anyone suggest is everything is running OK or there is
some problem.
Your suggestions will be highly appreciated.
Regards,
PG

Hello,
Did you recalculate full DB statistics after the last system copy from PRD to QA ?
This is very often forgotten, leading to long elapse times in select statements.
Check via DB20 on table ACCTCR from when latest DB statistics date.
Eventually rebuild all indexes from ACCTCR, this can be done online via ABAP RSANAORA if you are running Oracle.
You can also perform an SQL trace on the current running process to see if the select from the client copy is running correctly.
I also know that ACCTCR is a table containing transactional data and most of the time it contains a lot of data.
II suppose you are running a client copy with profile SAP_ALL on QA based on a copy of PRD ?
This means that you will end up with 2 production clients in QA ?
Is your QA system sized for this ?
Another question that you can ask your client, is data from ACCTCR really needed on QA on both clients.
If not it is maybe better to start an archiving based on SAP Note :
Note 83076 - MM_ACCTIT: Archiving programs for ACCTIT, ACCTHD, ACCTCR
Followed by a new client copy.
Success.

The import is in post processing. It digs through all the documents and adapts them to the new client. Most of the tables in the application area have a "MANDT" (= client) field which needs to be changed. Depending of the size of the client this can take a huge amount of time.
You can try to improve the speed by updating the table statistics for table D010INC.

Urxvt taking too much time to start [solved]

It gives no error message, and takes way much more time to startup then xterm. Any idea of what might be the fault?
(I've tried mrxvt, it starts very quickly, but I found it a little ugly, and had some problems with accented characters).
Last edited by andre.ramaciotti (2007-12-15 21:32:54)

The font is causing the long start, if you are not using the default one. I had that issue for a long time untill I added the following line to my .Xdefaults:
urxvt*font: xft:Bitstream Vera Sans Mono:pixelsize=11
Since then the terminal schocks me, because it starts to fast. ;-)
The next point is to use it in server and client mode. That allows more instances not letting the memory footprint to get bigger and maks it snappier. But this point isn't really important since I don't recognize any difference on my 7 year old box.

SAP GUI taking too much time to open transactions

Hi guys,
i have done system copy from Production to Quality server completely.
after that i started SAP on Quality server, it is taking too much time for opening SAP transactions (it is going in compilation mode).
i started SGEN, but it is giving time_out errors. please help me on this issue.
MY hardware details on quality server
operating system : SuSE Linux 10 SP2
Database : 10.2.0.2
SAP : ECC 6.0 SR2
RAM size : 8 GB
Hard disk space : 500 GB
swap space : 16 GB.

Ramesh

Hi,
>i started SGEN, but it is giving time_out errors. please help me on this issue.
You are supposed to run SGEN as a batch job and so, it should be possible to get time out errors.
I've seen Full SGEN lasting from 3 hours on high end systems up to 8 full days on PC hardware...

Taking too much time to load application

Hi,
I have deployed a j2ee application on oracle 10g version 10.1.2.0.2. But the application is taking too much time to load. After loading ,everything works fast.
I have another 10g server (same version) in which the same application is loading very fast.

Hi this is what the solution given by your link
A.1.6 Connection Timeouts Through a Stateful Firewall Affect System Performance
Problem
To improve performance the mod_oc4j component in each Oracle HTTP Server process maintains open TCP connections to the AJP port within each OC4J instance it sends requests to.
In situations where a firewall exists between OHS and OC4J, packages sent via AJP are rejected if the connections can be idle for periods in excess of the inactivity timeout of stateful firewalls.
However, the AJP socket is not closed; as long as the socket remains open, the worker thread is tied to it and is never returned to the thread pool. OC4J will continue to create more threads, and will eventually exhaust system resources.
Solution
The OHS TCP connection must be kept "alive" to avoid firewall timeout issues. This can be accomplished using a combination of OC4J configuration parameters and Apache runtime properties.
Set the following parameters in the httpd.conf or mod_oc4j.conf configuration files. Note that the value of Oc4jConnTimeout sets the length of inactivity, in seconds, before the session is considered inactive.
Oc4jUserKeepalive on
Oc4jConnTimeout 12000 (or a similar value)
Also set the following AJP property at OC4J startup to enable OC4J to close AJP sockets in the event that a connection between OHS and OC4J is dropped due to a firewall timeout:
ajp.keepalive=true
For example:
java -Dajp.keepalive=true -jar oc4j.jar
Please tell me where or which file i should put the option
java -Dajp.keepalive=true -jar oc4j.jar ??????/

Taking too much time in Rules(DTP Schedule run)

Hi,
I am Scheduling the DTP which have filters to minimize the load data.
when i run the DTP it is taking too much time in the "rules" (i can see the DTP monitor ststus package by pakage and step by step like "Start routine" "rules" and "End Routine")
here it is consuming too much time in Rules Mapping.
what is the problem and any solutions please...
regards,
sree

Hi,
Time taken at "rules" depends on the complexity involved there in ur routine. If it is a complex calculation it will take time.
Also check ur DTP batch settings, ie how many no. of background processes used to perform DTP, Job class.
U can find these :
goto DTP, select goto menu and select "Settings for Batch Manager".
In the screen increase no of Processes from 3 to higher no(max 9).
ChaNGE job class to 'A'.
If ur DTP is still running , cancel it ie Kill the DTP, delete from the Cube,
Change these settings and run ur DTP one more time.
U can observer the difference.

Taking too much time using BufferedWriter to write to a file

Hi,
I'm using the method extractItems() which is given below to write data to a file. This method is taking too much time to execute when the number of records in the enumeration is 10000 and above. To be precise it takes around 70 minutes. The writing pauses intermittently for 20 seconds after writing a few lines and sometimes for much more. Has somebody faced this problem before and if so what could be the problem. This is a very high priority work and it would be really helpful if someone could give me some info on this.
Thanks in advance.
public String extractItems() throws InternalServerException{
try{
               String extractFileName = getExtractFileName();
               FileWriter fileWriter = new FileWriter(extractFileName);

Hi fiontan,
Thanks a lot for the response!!!
Yeah!! I kow it's a lotta code, but i thought it'd be more informative if the whole function was quoted.
I'm in fact using the PrintWriter to wrap the BufferedWriter but am not using the print() method.
Does it save any time by using the print() method??
The place where the delay is occurring is the wile loop shown below:
            while(allitems.hasMoreElements()){
            String aRow = "";
                XDItem item = (XDItem)allitems.nextElement();
                for(int i =0 ; i < props.length; i++){
                     String value = item.getStringValue(props);
     if(value == null || value.equalsIgnoreCase("null"))
          value = "";
                         if(i == 0)
                              aRow = value;
                         else
                              aRow += ("\t" + value);
startTime1 = System.currentTimeMillis();
System.out.println("time here is--before-writing to buffer --out.flush() done: " +startTime1);
bufferWrt.write(aRow.toCharArray());
out.flush();//added by rosmon to check extra time taken for extraction//
bufferWrt.flush();//added by rosmon to check extra time taken for extraction//
bufferWrt.newLine();
startTime2 = System.currentTimeMillis();
System.out.println("time here is--after-writing to buffer : " +startTime2);
What exactly happens is that after a few loops it just seems to sleep for around 20 seconds and then again starts off and ............it goes on till the records are done.
Please do lemme know if you have any idea as to why this is happening !!!!! This bug is giving me the scare.
thanks in advance

I having issue with my Iphone 4 while playing music its taking too much time to play

I am using Iphone which is taking too much time to play music & some time its shows one album cover and playing others song please help and let me know whats the issue

Hello Sanjay,
I would recommend steps 1, 3, and 5 from our iPhone Troubleshooting Assistant found here: http://www.apple.com/support/iphone/assistant/phone/#section_1
Here is step 1 to get you started.
Restart iPhone
To restart iPhone, first turn iPhone off by pressing and holding the Sleep/Wake button until a red slider appears. Slide your finger across the slider and iPhone will turn off after a few moments.
Next, turn iPhone on by pressing and holding the Sleep/Wake button until the Apple logo appears.
Is iPhone not responding? To reset iPhone, press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds, until the Apple logo appears.
If your device does not turn on or displays a red battery icon, try recharging next.
Take care,
Sterling

Why it is taking too much time to kill the process?

Hi All,
Today,one of my user ran the calc script and the process is taking too much time, then i kill the process. I am wondering about one thing here even it is taking too long to kill the process, generally it will not take more than 2 sec. I did this through EAS.
After that I ran Maxl statement
alter system kill request 552599515;
there is no use at all.
Please reply if you have any solutions to kill this process.
Thanks in advance.
Ram.

Hi Ram,
1. Firstly, How much time does your calculation scripts normally run.
2. While it was running, you can go to the logs and monitor where exactly the script is taking time .
3. Sometimes, it does take time to cancel a transaction ( as it might be in between).
4. Maxl is always good to kill ,as you did . It should be succesful . Check the logs what it says ,and also the "sessions" which might say "terminating" and finish it off.
5. If nothing works ,and in the worst case scenarion , if its taking time without doing anything. Then log off all the users and stop the databas and start it .
6. Do log off all the users, so that you dont corrupt any filter related sec file.
Be very careful , if its production ( and I assume you have latest backups)

BPC application is taking too much time to load

Hi experts!
I'm facing a very weird problem...
We've developed a BPC application (app name: USM).
This application is taking too much time to be loaded in some computers (around 8 minutes to load). Yes, in SOME computers.
There is around 100.000 registers in the database and most coming from material master data.
If I try to load this USM application in another computer, the process loads smoothly. The computer's hardware is all the same, the server is hyper estimated and everyone is in the same network.
I talked to infrastructure departament and we made several tests. We run BPC on the server (loaded quickly), on several computers (some loads quickly, others don't), used wireless and cable connection (got all the same result) and checked communication between BW and BPC but it is ok.
After all, I tried to load APSHEL application in the same enviroment and it loaded intantly. So, I guess it is something wrong with my application. But if was this, I suppose it should happen to all computers and not only with part of them.
Have anybody ever seen something like this?
Thank you in advance.

Hi Rubens,
I would try making a couple of test:
1. I will install the client in a machine that is located in the same network segment, or try using a vpn that comunicates with the server bypassing all security devices, only to see if the network it's the problem.
2. Making a full optimize of one application to see if maybe the problem it's related to the segmentation of the cubes (i don't think that this is the problem but give it a try).
It is very wierd that in some computers happends and in others don't... also try to clean up the local cache of the applications in those computers that are giving to you bad performce and retry.
hope it helps,

Full DTP taking too much time to load

Hi All ,
I am facing an issue where a DTP is taking too much time to load data from DSO to Cube via PC and also while manually running it.
There are 6 such similar DTP's which load data for different countries(different DSO's and Cubes as source and target respectively) for last 7 days based on GI Date. All the DTP's are pulling almost same no. of records and finish within 25-30 min. But only one DTP takes around 3 hours. The problem started couple of days back.
I have change the Parallel processes from 3->4->5 and packet size from 50,000->10,000->1.00.000 but no improvement. Also want to mention that all the source DSO's and target Cubes have the same structure. All the transformations have Field Routines and End Routines.
Can you all please share some pointers which can help.
Thanks

Report taking too much time in the portal

Hi freiends,
we have developed a report on the ods,and we publish the same on the portal.
the problem is when the users are executing the report at the same time it is taking too much time.because of this the perfoemance is very poor.
is there any way to sort out this issue,like can we send the report to the individual user's mail id
so that they can not log in to the portal
or can we create the same report on the cube.
what could be the main difference if the report made on the cube or ods?
please help me
thanks in advance

Hi
Try this to improve performance of query
Find the query Run-time
where to find the query Run-time ?
557870 'FAQ BW Query Performance'
130696 - Performance trace in BW
This info may be helpful.
General tips
Using aggregates and compression.
Using less and complex cell definitions if possible.
1. Avoid using too many nav. attr
2. Avoid RKF and CKF
3. Many chars in row.
By using T-codes ST03 or ST03N
Go to transaction ST03 > switch to expert mode > from left side menu > and there in system load history and distribution for a particular day > check query execution time.
/people/andreas.vogel/blog/2007/04/08/statistical-records-part-4-how-to-read-st03n-datasets-from-db-in-nw2004
/people/andreas.vogel/blog/2007/03/16/how-to-read-st03n-datasets-from-db
Try table rsddstats to get the statistics
Using cache memory will decrease the loading time of the report.
Run reporting agent at night and sending results to email. This will ensure use of OLAP cache. So later report execution will retrieve the result faster from the OLAP cache.
Also try
1. Use different parameters in ST03 to see the two important parameters aggregation ratio and records transferred to F/E to DB selected.
2. Use the program SAP_INFOCUBE_DESIGNS (Performance of BW infocubes) to see the aggregation ratio for the cube. If the cube does not appear in the list of this report, try to run RSRV checks on the cube and aggregates.
Go to SE38 > Run the program SAP_INFOCUBE_DESIGNS
It will shown dimension Vs Fact tables Size in percent.If you mean speed of queries on a cube as performance metric of cube,measure query runtime.
3. To check the performance of the aggregates,see the columns valuation and usage in aggregates.
Open the Aggregates...and observe VALUATION and USAGE columns.
"---" sign is the valuation of the aggregate. You can say -3 is the valuation of the aggregate design and usage. ++ means that its compression is good and access is also more (in effect, performance is good). If you check its compression ratio, it must be good. -- means the compression ratio is not so good and access is also not so good (performance is not so good).The more is the positives...more is useful the aggregate and more it satisfies the number of queries. The greater the number of minus signs, the worse the evaluation of the aggregate. The larger the number of plus signs, the better the evaluation of the aggregate.
if "-----" then it means it just an overhead. Aggregate can potentially be deleted and "+++++" means Aggregate is potentially very useful.
In valuation column,if there are more positive sign it means that the aggregate performance is good and it is useful to have this aggregate.But if it has more negative sign it means we need not better use that aggregate.
In usage column,we will come to know how far the aggregate has been used in query.
Thus we can check the performance of the aggregate.

performance ISSUE related to AGGREGATE
Note 356732 - Performance Tuning for Queries with Aggregates
Note 166433 - Options for finding aggregates (find optimal aggregates for an InfoCube)
4. Run your query in RSRT and run the query in the debug mode. Select "Display Aggregates Found" and "Do not use cache" in the debug mode. This will tell you if it hit any aggregates while running. If it does not show any aggregates, you might want to redesign your aggregates for the query.
Also your query performance can depend upon criteria and since you have given selection only on one infoprovider...just check if you are selecting huge amount of data in the report
Check for the query read mode in RSRT.(whether its A,X or H)..advisable read mode is X.
5. In BI 7 statistics need to be activated for ST03 and BI admin cockpit to work.
By implementing BW Statistics Business Content - you need to install, feed data and through ready made reports which for analysis.

You can go to T-Code DB20 which gives you all the performance related information like
Partitions
Databases
Schemas
Buffer Pools
Tablespaces etc
use tool RSDDK_CHECK_AGGREGATE in se38 to check for the corrupt aggregates
If aggregates contain incorrect data, you must regenerate them.
202469 - Using aggregate check tool
Note 646402 - Programs for checking aggregates (as of BW 3.0B SP15)
You can find out whether an aggregate is usefull or useless you can find out through a proccess of checking the tables RSDDSTATAGGRDEF*
Run the query in RSRT with statistics execute and come back you will get STATUID... copy this and check in the table...
This gives you exactly which infoobjects it's hitting, if any one of the object is missing it's useless aggregate.

Check SE11 > table RSDDAGGRDIR . You can find the last callup in the table.

Can i have any solution for the above problem let me know .
Thanks & regards,
Sridhar M.

Hello Manoj,
Thanks for your quick response, Previously the server has 4GB RAM and now also it has same.
Yesterday i found some more information, like deployed(through SDM) applications also take some memory at the time of starting the J2EE server...Is it right?
Any other cause...let me know
Thanks & Regards,
Sridhar M.
