Oracle spawning parallel 128 processes when queried from Cognos

Hi,
I am querying a parallel enabled table with DOP set to default. Oracle 11.2 is installed on a 16 core machine while Cognos sits on a 4 core linux system. When querying the same table fromToad, I observe 32 parallel processes. Any thoughts as to why the difference and why that many number of processes get spawned from Cognos?
Thanks

What and what are you runnng and how are they configured?
I ask this because what you are seeing could be as a reulst of so many factors.
An example is that if you are using Planning Contributor, then you are likely to have more processes reading and writing to the database at the same time. The number of processes will then depend on serveral issues. For instance the number of CPUs on the box, the number of Contributor Applications, the number of Publish Containers and the interval the jobs are configured to run. Using a scenario where you have a single monitorin job on a 2 cpu box for 10 Contributor Applications. Ths may spawn up to 20 processes. To make things worse, if you happen to have some of the previous 20 processes not completing before the next job interval, then it adds more to the number you see.

Delay when querying from CUBE_TABLE object, what is it?

Hi Guys,
We are using Oracle OLAP 11.2.0.2.0 with an 11g Cube, 7 Dimensions, Compressed and partitioned by Month.
We have run into a performance issue when implementing OBIEE.
The main issue we have is a delay while drilling on a hierarchy. Users have been waiting 7-12 seconds per drill on a hierarchy, and the query is only returning a few cells of data. We have managed to isolate this to slow performing queries on CUBE_TABLE.
For example, the following query returns one cell of data:
SELECT FINSTMNT_VIEW.BASE, FINSTMNT_VIEW.REPORT_TYPE, FINSTMNT_VIEW.COMPANY, FINSTMNT_VIEW.SCENARIO, FINSTMNT_VIEW.PRODUCT, FINSTMNT_VIEW.ACCOUNT, FINSTMNT_VIEW.SITE, FINSTMNT_VIEW.TIME
FROM "SCHEMA1".FINSTMNT_VIEW FINSTMNT_VIEW
WHERE
FINSTMNT_VIEW.REPORT_TYPE IN ('MTD' )
AND FINSTMNT_VIEW.COMPANY IN ('E01' )
AND FINSTMNT_VIEW.SCENARIO IN ('ACTUAL' )
AND FINSTMNT_VIEW.PRODUCT IN ('PT' )
AND FINSTMNT_VIEW.ACCOUNT IN ('APBIT' )
AND FINSTMNT_VIEW.SITE IN ('C010885' )
AND FINSTMNT_VIEW.TIME IN ('JUN11' ) ;
1 Row selected in 4.524 Seconds
Note: FINSTMNT_VIEW is the automatically generated cube view.
CREATE OR REPLACE FORCE VIEW "SCHEMA1"."FINSTMNT_VIEW" ("BASE","REPORT_TYPE", "COMPANY", "SCENARIO", "PRODUCT", "ACCOUNT", "SITE", "TIME")
AS
SELECT "BASE", "REPORT_TYPE", "COMPANY", "SCENARIO", "PRODUCT", "ACCOUNT", "SITE", "TIME"
FROM TABLE(CUBE_TABLE('"SCHEMA1"."FINSTMNT"') ) ;
If we increase the amount of data returned by adding to the query, it only increased the query time by .4 seconds
SELECT FINSTMNT_VIEW.BASE, FINSTMNT_VIEW.REPORT_TYPE, FINSTMNT_VIEW.COMPANY, FINSTMNT_VIEW.SCENARIO, FINSTMNT_VIEW.PRODUCT, FINSTMNT_VIEW.ACCOUNT, FINSTMNT_VIEW.SITE, FINSTMNT_VIEW.TIME
FROM "SCHEMA1".FINSTMNT_VIEW FINSTMNT_VIEW
WHERE
FINSTMNT_VIEW.REPORT_TYPE IN ('MTD' )
AND FINSTMNT_VIEW.COMPANY IN ('E01' )
AND FINSTMNT_VIEW.SCENARIO IN ('ACTUAL' )
AND FINSTMNT_VIEW.PRODUCT IN ('PT' )
AND FINSTMNT_VIEW.ACCOUNT IN ('APBIT' )
AND FINSTMNT_VIEW.SITE IN ('C010885', 'C010886', 'C010891', 'C010892', 'C010887', 'C010888', 'C010897', 'C010893', 'C010890', 'C010894', 'C010896', 'C010899' )
AND FINSTMNT_VIEW.TIME IN ('JUN11' ) ;
12 rows selected - In 4.977 Seconds
If we increase the data returned even more:
SELECT FINSTMNT_VIEW.BASE, FINSTMNT_VIEW.REPORT_TYPE, FINSTMNT_VIEW.COMPANY, FINSTMNT_VIEW.SCENARIO, FINSTMNT_VIEW.PRODUCT, FINSTMNT_VIEW.ACCOUNT, FINSTMNT_VIEW.SITE, FINSTMNT_VIEW.TIME
FROM "SCHEMA1".FINSTMNT_VIEW FINSTMNT_VIEW
WHERE
FINSTMNT_VIEW.REPORT_TYPE IN ('MTD' )
AND FINSTMNT_VIEW.COMPANY IN ('ET', 'E01', 'E02', 'E03', 'E04' )
AND FINSTMNT_VIEW.SCENARIO IN ('ACTUAL' )
AND FINSTMNT_VIEW.PRODUCT IN ('PT', 'P00' )
AND FINSTMNT_VIEW.ACCOUNT IN ('APBIT' )
AND FINSTMNT_VIEW.SITE IN ('C010885', 'C010886', 'C010891', 'C010892', 'C010887', 'C010888', 'C010897', 'C010893', 'C010890', 'C010894', 'C010896', 'C010899' )
AND FINSTMNT_VIEW.TIME IN ('JUN11', 'JUL11', 'AUG11', 'SEP11', 'OCT11', 'NOV11', 'DEC11', 'JAN12') ;
118 rows selected - In 14.213 Seconds
If we take the time for each query and divide by the number of rows, we can see that querying more data results in a much more efficient query:
Time/Rows returned:
1 Row - 4.524
12 Rows - 0.4147
118 Rows - 0.120449153
It seems like there is an initial delay of approx 4 seconds when querying the CUBE_TABLE object. Using AWM to query the same data using LIMIT and RPR is almost instantaneous...
Can anyone explain what this delay is, and if there is any way to optimise the query?
Could it be the AW getting attached before each query?
Big thanks to anyone that can help!

Thanks Nasar,
I have run a number of queries with logging enabled, the things you mentioned all look good:
Loop Optimization: GDILoopOpt     COMPLETED
Selection filter: FILTER_LIMITS_FAST     7
ROWS_FAILED_FILTER     0
ROWS_RETURNED     1
Predicates: 7 pruned out of 7 predicates
The longest action I have seen in the log is the PAGING operation... but I do not see this on all queries.
Time Total Time OPERATION
2.263     27.864          PAGING     DYN_PAGEPOOL     TRACE     GREW     9926KB to 59577KB

What is strange is that the cube operation log does not account for all of the query time. For example:
SELECT "BASE_LVL" FROM TABLE(CUBE_TABLE('"EXAMPLE"."FINSTMNT"'))
WHERE
"RPT_TYPE" = 'MTD' AND
"ENTITY" = 'ET' AND
"SCENARIO" = 'ACTUAL' AND
"PRODUCT" = 'PT' AND
"GL_ACCOUNT" = 'APBIT' AND
"CENTRE" = 'TOTAL' AND
"TIME" = 'YR09';
This query returns in 6.006 seconds using SQL Developer, if I then take the CUBE_OPERATION_LOG for this query and subtract the start time from the end time, I only get 1.67 seconds. This leaves 4.3 seconds unaccounted for... This is the same with the my other queries, see actual time and logged time below:
Query     Actual     Logged      Variance
S3     6.006     1.67     4.336
L1     18.128     13.776     4.352
S1     4.461     0.203     4.258

S2     5.882     1.575     4.307
Any ideas on what this could be or how I can capture this 4.3 second overhead?
Your help has been greatly appreciated.

Insert Chinese data in Oracle but cannot be shown when querying

I use:
JDK 1.1.8, Oracle 8i, thin driver.
The OS is HP Unix.
I successfully insert the Chinese Big5 encoding data into Oracle. But I can't show the Chinese again when I querying.
Here's my code:
Class.forName("oracle.jdbc.driver.OracleDriver");
con = DriverManager.getConnection
("jdbc:oracle:thin:@hpdev.wisers.com:1521
:research", "corp", "corp");
stmt = con.createStatement();
String sqlString = new String("insert into filetable values(1,"
+ var1 + "," + var2 + "...)");
stmt.executeQuery(sqlString);
Then I show the result by "select * from filetable;". However, the Chinese Big5 encoding data cannot be shown, "+??.." is shown instead. There is no problem when the data is in English.
I have tried
byte[] sqlStringBytes = sqlString.getBytes("Big5");
String newsql = new String(sqlStringBytes,"Big5");
stmt.executeQuery(newsql);
but still not successful.
My NLS_LANG is
AMERICAN_AMERICA.ZHT16BIG5
How can I make use of this variable? How can I solve the problem?
I am very in hurry. The program deadline is coming!! Help please!!
null

Your code looks fine ?
What's your db character set ?
I successfully insert the Chinese Big5 encoding data into Oracle.How do you know this ? Did you verify with SQL*Plus to see whether the data can be retrieved ?
What are var1 and var2 ?

Slow processing when clicking from song to song - the wheel keeps spinning!

When I click from song to song within iTunes 8.2.1 (6) (my music is kept on an external hard drive with a USB 2.0 connection), it takes an additional minute for it to play - the wheel keeps spinning - and this increases my workload by over 500%! Any idea why this is happening? Any way to correct it?
I used to occur when using 8.0, but then the 8.1 upgrade corrected this problem, but now that 8.2 is up, the wheel spins and spins and spins.

Query from source table takes lots of time

I have to load data from an Oracle table which has millions of records. The loading knowledge module I am using is 'lkm sql to oracle'.
I see that the query from the source database takes lot of time and doing a full table scan where as it supposed to be using an index.
I dont have any lkm with 'lkm oracle to oracle'. Some how I need to add a hint to this source query. How I can do this?

This LKM is not indicated to large volume of data, try to use LKM Oracle to Oracle (DBLINK), see ODI KMs documentation for more information.
Related to HINTS you can add this with KM options, see that some Oracle ODI11g new KMs already have some options to do it, so you can put the hint on interface options of KM or define the temp index on the interface

PC session hangs when launch a query from Oracle 9i client to 10g database

I have a pc with Oracle 9.2.0.1.0 client installed. The database server level is 10.1.0.5.
When I launch a query from a client session the pc sesssion locks up and doesn't return any results. When I launch the same query from the database server , or from other pcs with Oracle client 10 installed , I get results almost immediately from the query.
The pc in question is running Windows XP Service pack 2. Other queries run fine from the pc.
Are there are any known issues with Oracle 9 clients querying an Oracle 10 database ?

Thank you for your reply. No, I must admit I didn't think of looking at the wait events. I will look at this as soon as I get a chance.
Thanks again for your suggestion.

Oracle Server 11.2.0.1.0 64-bit fails when invoked from InstallShield

I'm trying to install the Oracle Server 11.2.0.1.0 64-bit on Windows 2008 SP1 from the InstallShield 2010.
The installation is silent. Invoked by command line:
J:\Oracle_11.2.0_x64\OracleServer_11.2.0.1_x64\setup.exe ORACLE_HOME_NAME="ARAXI_11" -silent -nowelcome -force -nowait -noconsole -loglevel fine -noconfig -ignoreSysPrereqs use_prereq_checker=false -responseFile C:\Oracle\11.2.0\installation\scripts\SVRCUSTOM11.2.0.rsp
The problem is that when the command is invoked from command line (cmd), the installation is successful.
However, when the same command is invoked from under the InstallShield, the installation fails on Architecture requirement check:
INFO: *********************************************
INFO: Architecture: This is a prerequisite condition to test whether the system has a certified architecture.

The questions:
1. Why the requirement checks give different results when installation is invoked from CMD and from InstallShield?
2. Why the requirement checks are done despite the parameters "-ignoreSysPrereqs" and "use_prereq_checker=false"?
3. What should I do to get the installation pass (either remove the check or make it satisfying)?
PS. The 32 bit Oracle Server installation on Windows 2003 works without problem when invoked from InstallShield.

Please use 2008R2 if you want to install 11gR2 versionThank you for that update. Possibly it will help me to solve another trouble.
Regarding the problem I described, the issue is that I install Oracle Client 32 bit prior to trying to install Oracle Servier 64 bit.
The Oracle Client setup had started RemoteExecService.exe 32 bit process. And the process remained running after the installation completed.
The Oracle Server setup utilizes the running RemoteExecService.exe process. Since the process is 32 bit, the architecture requirement check had failed.
I've added to my script killing the process
taskkill /F /IM RemoteExecService.exe
before invoking the Oracle Server installation.
That way the Oracle Server setup starts another RemoteExecService.exe process and the new process is 64 bit.
The architecture requirement succeed.

Help with translating SQL query from SQL Server syntax to Oracle syntax

Hi,
is it someone that can help me translate following SQL query from SQL Server syntax to Oracle syntax.

Fault information from bpel process when exception happens

How to extract all the fault information from bpel process when exception happens?
Are there any other methods other than "ora:getFaultName(), ora:getFaultAsString()"
When I use "ora:getFaultName(), ora:getFaultAsString()", I get the below message,so I am wondering whether
I can get any more information about the exception as mentioned below - "detailed root cause described in the exception message" -> how do I get it?
Check the detailed root cause described in the exception message text and verify that the XPath query is correct.

Hi,
As far as I know, it's not possible to get the exception message with a catch all. You need to catch each exception separately, and the you will be able to get each message.

Oracle report problem-Passing a column value from a query block to another

Hi I am facing a problem in oracle reports.
I have 3 query blocks say Q1,Q2 and Q3.
From Q1 I get a tblkey coulmn and for each value of tblkey I need to pass it on to Q2 which gives me a status and now finally Q3 will take tblkey and status to give me final output.
Can somebody please tell me how I can do it?
Thanks,
Avin

Depending on your report requirement, you may do a join of Q1, Q2, and Q3; or keep all Qs and for Q3 use subqueries ...
Select ... from ... where tblkey, status in (
select tblkey, status from ... where tblkey in (
select tblkey from .... where .... ) )
Good luck.

Has anyone had issues with poor image quality when using lightroom to process raw images from Canon 7dmk2

Hi everyone..
..I have been having image quality issues when using Lightroom to process raw files from a 7d mk2... They are all soft with poor clarity.....tonight in despair I tried processing them using canon's software and they are totally different..."much better"
anyone else had similar problems....Andy

I have a 7D2 and have not had what I interpret as poor image quality that has anything to do with the camera.
Can you post a screenshot of what you’re seeing and what specifically you don’t like? Maybe there is something you can do differently or at least there may be an explanation for what you’re seeing.
And if you have a raw image that you wouldn’t mind sharing in a public forum, upload to http://www.dropbox.com/ then post a public share link to it in a reply, here.
In other words post a screenshot of what you see in LR, another of what you see using DPP, and a link to the raw file you’re processing.
