Discoverer Query is taking too much time

Hi,
I am having performance problems with some queries in Discoverer(Relational). Discoverer is taking around 30 minutes to run the report. But if I run the same query through TOAD it takes only 5 to 6 seconds. Why it is so ?
Structure of Report:
The report is using crosstab with 3 dimensions on the left side and 3 dimensions on the page items.
Why the performance in the discoverer is slow and how can I improve it ?
Thanks & Kind Regards
Rana

Hi all
Russ' comments are correct. When you use crosstabs or page items, Discoverer has to execute the entire query before it can bring back any results. This is a known factor that should be taken into account when end users create workbooks.
The following conditions will greatly impact performance:
1. Crosstabs with many items on the left axis
2. Multiple Crosstab values
3. Page items with a large set of values,
4. Crosstabs or page items that use complex calculations,
5. Multiple page items
Thus, users must avoid building worksheets that use too many of the above. As commented previously, this is well documented in the forums and on the Oracle website and should not come up by surprise. If it does then either suitable training has not been given to the end users or Oracle's own end user documentation has not been read. Section 6 of the Discoverer Plus user guide has the following advice:
Whether you are using Discoverer Plus Relational to perform ad hoc queries, or to create reports for other end users, you want to minimize the time it takes to run queries and reports. By following a few simple design guidelines, you can maximize Discoverer performance.
Where possible:
use tabular reports rather than cross-tabular reports
minimize the number of page items in reports
avoid wide cross tabular report
avoid creating reports that return tens of thousands of rows
provide parameters to reduce the amount of data produced
minimize the number of worksheets in workbooks
remove extraneous worksheets from workbooks (especially if end users frequently use Discoverer’s export option, see Notes below)
Notes:
When end users export data in Discoverer Plus Relational or Discoverer Viewer, they can export either the current worksheet or all the worksheets. In other words, they cannot selectively choose the worksheets to be exported. Remove extraneous worksheets so that extra data is not included when end users export all worksheets.
I hope this helps
Regards
Michael

Report is taking too much time when running from parameter form

Dear All
I have developed report in oracle reports bulider 10g. while running it from report builder data is coming very fast.
But, If it is running from parameter form it is taking too much time to format report in PDF.
Please suggest any configuration or setting if anybody is having Idea.
Thanks

Hi,
The first thing to check is whether the query is running to completion in TOAD. By default, TOAD just selects the first 50 rows, where as Discoverer must return all the rows before displaying results if a crosstab report is used.
Secondly, check that the queries and the explain plans are the same in Discoverer and Toad. Although, Discoverer shows the SQL in the SQL inspector this isn't necessarily the SQL actually sent to the database. Use TOAD to interogate the Discoverer session to determine the actual SQL and compare this SQL and explain plan to SQL you ran in TOAD.
Thirdly, check that the session context is the same in both cases. So check that any custom contexts and the USER_ENV context is the same, and if any security packages or VPD policies are used in the SQL that these have been initialised the same.
If you still cannot determine the difference then trace both sessions.

Still the report is taking too much time

Hi All,
When i refresh a webi report the report is taken too much time to refresh(open).
In back end i have checked all the connections, contexts, cardinalities, joins, conditions...etc, in webi i have enabled the the check box 'query stripping'.
but still the report is taking too much time, i didn't identified the problem?
Please help me on this.
Thanks in advance..

Hi Mark,
How many queries are there--2
How many rows are returned--- 2000+
Are all measures defined with aggregates-- Yes
What is the array fetch size? (I1000 if it isn't already)

Simple APD is taking too much time in running

Hi All,
We have one APD created on our developement system which is taking too much time in running.
This APD is fetching data from a Query having only 1200 records and directly putting into a master attribute.
The Query is running fine in RSRT transaction and giving output within 5 seconds but in APD if I do display data over Query it is taking too much time.
The APD is taking arrount 1.20 hours in running.
Thanks in advance!!

Hi,
When a query runs in APD it normally takes much, much longer than it takes in RSRT. Run times such as what you are saying (5secs in RSRT and >1.5 hrs in APD) are quite normal; I've seen them in some of my queries running for several hours in APD as well.
You just have to wait for it to complete.

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 ??????/

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.
regards
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.

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

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

Hi,

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.
