Server0 process taking too much time

Hi All,
Once i start the Netweaver server, the server) process taking too much time.
When i was installed Netweaver that time 13 min, after 2 months 18 min.. then 25 min now it is taking 35 minutes.... to become green color.
Why it is taking too much time, what might be the cause.....
Give some ideas to solve this problem..............
The server0 developer trace has this information continuously 6 to 7 times...

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

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.

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)

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.
When I checked the apache error logs found this :-

Please HELP ME...

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.

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

While condition is taking too much time

I have a query that returns around 2100 records ( not many ! ) , when I am processing my result set with a while condition , it's taking too much time ( around 30 seconds ). Here is the code
public static GroupHierEntity load(Connection con)
     throws SQLException
     internalCustomer=false;
     String customerNameOfLogger = com.photomask.framework.ControlServlet.CUSTOMER_NAME;
if ( customerNameOfLogger.startsWith("DPI") || customerNameOfLogger.startsWith("DUPONT") || customerNameOfLogger==null || customerNameOfLogger.equals("") ||customerNameOfLogger.equals("Unavailable") )
{ internalCustomer=true;}
// System.out.println(" ***************** customer name of logger " + com.photomask.framework.ControlServlet.CUSTOMER_NAME + "internal customer " + internalCustomer);
// show all groups to internal customers and only their customer groups for external customers
if (internalCustomer) {
          stmtLoad = con.prepareStatement(sqlLoad);
     ResultSet rs = stmtLoad.executeQuery();
     return new GroupHierEntity(rs); }
     else
     stmtLoadExternal = con.prepareStatement(sqlLoadExternal);
     stmtLoadExternal.setString(1, customerNameOfLogger);
     stmtLoadExternal.setString(2, customerNameOfLogger);
     // System.out.println("***** sql " +sqlLoadExternal);
     ResultSet rs = stmtLoadExternal.executeQuery();
return new GroupHierEntity(rs);
GroupHierEntity ge = GroupHierEntity.load(con);
while(ge.next())
lvl = ge.getInt("lvl");
oid = ge.getLong("oid");
name = ge.getString("name");
if(internalCustomer) {
if (lvl == 2)
int i = getAlphaIndex(name);
super.setAppendRoot(alphaIndex);
gn = new GroupListDataNode(lvl+1,oid,name);
gn.setSelectable(true);
this.addNode(gn);
count++;
System.out.println("*** count "+ count);
ge.close();
========================
Then I removed every thing in the while clause and just run as it is , still it is taking same time ( 30 secs )
while(ge.next())
{count++;}
Why the while condition ( ge.next() ) is taking so much time ? Is there any other efficient way of reading the result set ?
Thanks ,
bala

I tried all these things. The query is not taking much time ( 1 sec ). but the resultset.next() is taking too much time. I counted the time by putting System.out.pr.. at various points to see whuch is taking how much time.
executeQuery() is only taking 1 sec. Processing the result set ( moving the cursor to next position ) is taking too much time.
I have similar queries that return some 800 rows , that only takes 1 sec.
I have doubt on resultset.next(). Any other alternative ?

ODS to CUBE load taking too much time..

Hi all ,
we are loading the data from our ZODS to ZCUBE, but the data load is taking too much time , we haven't created any indexes , we alsotried by making infosource for the ODS but still tha same problem .. It is always showing 0 from 345674 records that is the records are not getting extracted from ODS .
Can anybody help me in this regards , it is a bit urgent ..
Thanks in advance.

Hi,
there are a few you can check. First you should check if this job hasn't ended in a dump with ST22.
The next thing you can do, if the job doesn't end abnormaly, is to reduce the amount of records processed at the same time. Sometimes the system has trouble if the amount of records that it has to process is too large. Go to the InfoPackage -> DataS. Default Data Transfer -> Fill the maximum to 10% of de the default value. Try to run the load again.
If the job still doesn't finish then you have to check wether or not there are any ABAP routines and/or formula involved in the update rule ? Maybe they running in a loop.

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.

Delete query taking too much time

Hi All,
my delete query is taking too much time. around 1hr 30 min for 1.5 lac records.
Though I have dropped mv log on the table & disabled all the triggers on it.
Moreover deletion is based on primary key .
delete from table_name where primary_key in (values)
above is dummy format of my query.
can anyone please tell me what could be other reason that query is performing that slow.
Is there anything to check in DB other than triggers,mv log,constraints in order to improve the performance?
Please reply asap.

Delete is the most time consuming operation, as the whole record data has to be stored at the undo segments. On the other hand, there is a part of the query used to select records to delete that probably is adding an extra overhead to the process, the in (values) clause. It would be nice on your side to post another dummy from this (values) clause. I could figure out this is a subquery, and in order for you to obtain this list you have to run a inefficient query.
You can gather the execution plan so you can see where the most heavy part of th query is. This way a better tuning approach and a more accurate diagnostic can be issued.

Import taking too much time in oracle 7i

Hi Guys
I am trying to import a table of around 9600000 rows. on oracle 7i it is taking too much time. any suggestion or way i can speedup the process?
Thanks in advance
Khurana

Ok.
Note that it is "_disable_logging" not "disable_logging", but I don't have an Oracle 7 database to confirm if it works.
Been a long time since I used Oracle 7. Any reason why you have not upgraded ? Import should be much faster with 11g ...
For further tuning you would need to look at OS and DB performance to find bottlenecks. E.g run bstat / estat.
Other things to look at are disk performance, increase db_block_buffers, increase db_writer etc.

Try this First... You will Not Lose Any Data...
Turn the Phone Off...
Press and Hold the Sleep/Wake Button and the Home Button at the Same Time...
Wait for the Apple logo to Appear and then Disappear...
Usually takes about 15 - 20 Seconds... ( But can take Longer...)
