Owb job taking too much time to execute

While creating a job in OWB, I am using three tables,a joiner and an aggregator which are all joined through another joiner to load into the final table. The output is coming correct but the sql query generated is very complex having so many sub-queries. So, its taking so much time to execute. Pls help me in reducing the cost.
-KC

It depends on what kind of code it generates at each stage. The first step would be collect stats for all the tables used and check the SQL generated using EXPLAIN PLAN. See which sub-query or inline view creates the most cost.
Generate SQL at various stages and see if you can achieve the same with a different operator.
The other option would be passing HINTS to the tables selected.

AuthenticateAsClient is taking so much time

Hi
I am working on a client - server architecture for data transfer. I am using SSLStream for sending and receiving files.
I am using AuthenticateAsClient on client side to authenticate server but i am facing an issue.
1. my application getting stop after sending starts and never shows any error or progress. After debugging my code i found that AuthenticateAsClient is taking so much time and sometimes it never flow back to code.
So please help me to find out the solution for this issue.

Hi Amit,
Sorry for late.
I am not expert on certificate. But per my understanding test certificate can be used. But only recommended for testing purposes.
There is a tool called
MakeCert. This tool can create self-signed root certificate. And import it to trusted root certification authorities certificate store and trusted publishers certificate
store. It will works.
If above solution still can't resolve your issue and the issue is very urgent. I will suggest you to open one phone support ticket. This
is paid support case.

SetDataSource function taking too much time !

Hi,
We are using Crystal reports 2008 for developing our applications in Visual Studio .Net 2005 widows application.We are using Crystal viewer ActiveX control in our windows application for displaying the reports. The datasource we are using is strongly typed XSD files. And we have mutiple xsd files for each report with mutiple tabels in it.
We are using SetDataSource function for setting the data for each table from .Net code to report by push method. But it takes lot of time in this part.
Kindly Help.
Thanks,
Shyam S

Hi Johnathan,
We are passing the data from the database to crystal reports using XSD files.
These XSD dataset fiels are included in our project. And first we populate the data into the objects of these datasets files and use the setdatasource function of crystaldocument class to assign the data from the XSF tables to the respective table in the report.
The report database is constructed using these ADO.NET (XML) new connectin pointing to the XSD files.
And these tables which show in the report database are used in the report.
These setdatasource functions are taking around 20 seconds to process; eventhoug the dataset objects we have in the code are the same objects of the XSD files which are used in the report. so it is just like assignment of data from code to the report which should not be taking so much time. Also datasets doesn't return more than 20 rows.
We are using version 12.1.0.892 of crystal reports 2008. Yes i have installed SP1 for crystal reports 2008.
One more observation i have found is that the more the number of tables i have in the XSD file more the time it takes, eventhough i may be using only one table in that particular XSD file. I have checked this by noting the time differences by adding unwanted tables in the existing XSD files.
So i think eventhough i am assigning only one table using this statement, it loads the whole xsd file before loading the data
CrystalDocumentObj.Database.Tables["CON_InvoiceSummary"].SetDataSource(reportConfigurationDS.Tables["CON_InvoiceSummary"]);
Is there anything can be done ?
Thanks,

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 :-

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 ??????/

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 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 incollecting in business content activation

Hi all,
I am collecting business content object for activation. I have selected 0fiAA_cha object,while cllecting in the activation but it is taking too much time and then it asks for source
system authorisation and then throws error maximum run time exceded. i have selected data flow before there.
What can be the reason for it.
Please help..

Hi ,
You should also always try and have the latest BI content patch installed but I don't think this is the problem. It seems that there
are alot of objects to collect. Under 'grouping' you can select the option 'only necessary objects', please check if you can
use this option to install the objects that you need from content.
Best Regards,

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);
               BufferedWriter bufferWrt = new BufferedWriter(fileWriter);
               CXBusinessClassIfc editClass = new ExploreClassImpl(className, mdlMgr );
System.out.println("Before -1");
               CXPropertyInfoIfc[] propInfo = editClass.getClassPropertyInfo(configName);
System.out.println("After -1");
          PrintWriter out = new PrintWriter(bufferWrt);
System.out.println("Before -2");
          TemplateHeaderInfo.printHeaderInfo(propInfo, out, mdlMgr);
System.out.println("After -2");
XDItemSet itemSet = getItemsForObjectIds(catalogEditDO.getSelectedItems());
Enumeration allitems = itemSet.allItems();
System.out.println("the batch size : " +itemSet.getBatchSize());
XDForm frm = itemSet.getXDForm();
XDFormProperty[] props = frm.getXDFormProperties();
System.out.println("Before -3");
bufferWrt.newLine();
long startTime ,startTime1 ,startTime2 ,startTime3;
startTime = System.currentTimeMillis();
System.out.println("time here is--before-while : " +startTime);
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 --new: " +startTime1);
bufferWrt.write(aRow.toCharArray());
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);
startTime3 = System.currentTimeMillis();
System.out.println("time here is--after-while : " +startTime3);
               out.close();//added by rosmon to check extra time taken for extraction//
bufferWrt.close();
fileWriter.close();
System.out.println("After -3");
return extractFileName;
catch(Exception e){
               e.printStackTrace();
throw new InternalServerException(e.getMessage());

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

Taking too much time (1min) to connect to database

Hi,
I have oracle 10.2 and 10g application server.

Dear AnaTech,
i am going to ask not related this question which already you answered i am going to ask you about that how to connect forms6i and Developer 10g with OracleAS.
i have installed and working Developer Suite 10g Ver. 10.1.2 and also Form Builder 6i. On my other machine i installed and working Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 and also on the database machine i installed Oracle Enterprise Manager 10g Application Server Control 10.1.2.0.2.
my database conectivity with Developer suite Forms and Reports and also Form6i and Reports6i are working fine. no problem.
now the 1 question of mine is that when i try to run form6i through run from web i got this error. FRM-99999: error 18121 occured see the release not.
this and the main question of mine is this that how can i control my OracleAS 10g with forms because basically the functionality of OracleAS is Mid-Tier but i am not utilizing the Mid-tier i am using here Two-tier Envrionment even i installed 3-Tier Environment so tell me how i utilize it with 3-Tier..
I hope you don't mind that i ask this question here and also if you give me you email then we can discuss this in detail and i can be helpful of your great expertise. i also know and utilize my 3-tier real envrionment.
Waiting for your great response.

Taking too much time and not connecting to ipad software server

taking too much time and not connecting to ipad software server and not updating.. why

because everyone is doing the same thing you are... be patient, and you will get the update... I had to grab the update over 3G (it won't let you download or install, but it got me in the door) and then switch back to wifi and download and install.

View is taking to much time
