Help me in execution plan

Hi
can somebody help me to know the what are explain plan and execution plan?what is the differnce between them?
thankz in advance

What the plan is, EXPLAIN PLAN;
http://download.oracle.com/docs/cd/E11882_01/server.112/e16638/optimops.htm#PFGRF94595
Explain plan is a command which shows you the execution plan.
The execution can however change from the output generated by the EXPLAIN PLAN
How it can change,;

Help in TKPROF Output: Row Source Operation v.s Execution plan confusing

Hello,
Working with oracle 10g/widnows, and trying to understand from the TKPROF what is the purpose of the "Row Source operation" section.
From the "Row Source Operation" section the PMS_ROOM table is showing 16 rows selected, and accessed by an ACCESS FULL, and the following script gives another value.
select count(*) from pms_folio give the following.
COUNT(*)
148184
But in the execution plan section, the PMS_FOLIO table is accessed by ROW ID after index scan in the JIE_BITMAP_CONVERSION index
What really means Row Source operation compares to the execution plan and how both information should be read to fully know if the optimizer is not making wrong estimation?
furthermore readding 13594 buffers to fetch 2 rows, show the SQL Script itself is not sufficient, but the elapsed time is roughly 0.7seconds,but shrinking the # of buffers to be read should probably shrink the response time.
The following TKPROF output.
Thanks very much for your help

Your query is using bind variables. Explain Plan doesn't work exactly the same way -- it can't handle bind variables.
See http://www.oracle.com/technology/oramag/oracle/08-jan/o18asktom.html
In your output, the row source operations listing is the real execution.
The explain plan listing may well be misleading as Oracle uses cardinality estimates when trying to explain with bind variables.
Also, it seems that your plan table may be a 9i version, not the 10g PLAN_TABLE created by catplan.sql There are additional columns in the 10g PLAN_TABLE that explain uses well.
BTW, you start off with a mention of "PMS_ROOM" showing 16 rows, but it doesn't appear in the data you have presented.

Error while building execution plan

Hi, I'm trying to create an execution plan with container EBS 11.5.10 and subject area Project Analytics.
I get this error while building:

Thank you for helping me

Hi,
Find the what are all the subjectarea's in execution plan having the task 'SIL_PositionDimensionHierarchy_PostChangeTmp ', add the 'TASK_GROUP_Load_PositionHierarchy ' task group to those those subjectares.
Assemble your subject area's and build the execution plan again.
Thanks

Execution plan with Concatenation

Could anyone help in finding why concatenation is being used by optimizer and how can i avoid it.

Is there any better way to rewrite this sql OR is there any way to eliminate concatenation ?
Thanks

We cant use data_provider in the given query. We need to pull data irrespective of data_provider and it should be based on ENTITYID.
Yes table has only three partitions...
Not sure issue is due to concatenation....but we are in process to create desired indexes which will help for this sql.
In development we have created multicolumn index and below is the execution plan.....Also in development it takes just 4-5 seconds to execute. But in production it takes more than 8-9 minutes.
Below is the execution plan from Dev which seems to perform fast:

Query optimization - Query is taking long time even there is no table scan in execution plan

Hi All,
The below query execution is taking very long time even there are all required indexes present.
Also in execution plan there is no table scan. I did a lot of research but i am unable to find a solution.
Please help, this is required very urgently. Thanks in advance. :)

Effect of RLS policy (VPD) on execution plan of a query

Hi
I have been working on tuning of few queries. A RLS policy is defined on most of the tables which appends an extra where condition (something like AREA_CODE=1). I am not able to understand the effect of this extra where clause on the execution plan of the query. In the execution plan there is no mention of the clause added by VPD. In 10046 trace it does show the policy function being executed but nothing after that.
Can someone shed some light on the issue that has VPD any effect on the execution plan of the query ? Also would it matter whether the column on which VPD is applied, was indexed or non-indexed ?
Regards,
Amardeep Sidhu

VPD is supposed to be invisible - which is why you get minimal information about security predicates in the standard trace file. However, if you reference a table with a security preidcate in your query, the table is effectively replaced by an inline view of the form: "select * from original_table where {security_predicate}", and the result is then optimised. So the effects of the security predicate is just the same as you writing the predicate into the query.
Apart from your use of v$sql_plan to show the change in plan and the new predicates, you can see the effects of the predicates by setting event 10730 with 10046. In current versions of Oracle this causes the substitute view being printed in the trace file.
Bear in mind that security predicates can be very complex - including subqueries - so the effect isn't just that of including the selectivity of "another simple predicate".
Can someone shed some light on the issue that has VPD any effect on the execution plan of the query ? Also would it matter whether the column on which VPD is applied, was indexed or non-indexed ?
Think of the effect of changing the SQL by hand - and how you would need to optimise the resultant query. Sometimes you do need to modify your indexing to help the security predicates, sometimes it won't make enough difference to matter.

Same query at same time, but different execution plans from two schemas

Hi!
We just had some performance problems in our production system and I would like to ask for some advice from you.
We had a select-query that was run from USER1 on SCHEMA1, and it ran a table scan on a huge table.
Using session browser in TOAD I copied the Sql-statement, logged on SCHEMA1 and ran the same query. I got a different execution plan where I avoided the table scan.
So my question is:
How is it possible that the same query get different execution plans when running in two different schemas at the same time.
Some more information:
The user USER1 runs "alter session set current_schema=SCHEMA1;" when it logs on. Besides that it doesn't do anything so session parameter values are the same for USER1 and SCHEMA1.
SCHEMA1 is the schema owning the tables.
ALL_ROWS is used for both USER1 and SCHEMA1
Our database:
Oracle9i Enterprise Edition Release 9.2.0.8.0 - 64bit Production
PL/SQL Release 9.2.0.8.0 - Production
CORE 9.2.0.8.0 Production
TNS for Linux: Version 9.2.0.8.0 - Production
NLSRTL Version 9.2.0.8.0 - Production
Anybody has some suggestions to why I experience different execution plan for the same query, run at the same time, but from different users?

Thanks for clarification of the schema structure.
What happens if instead of setting the current session schema to SCHEMA1, if you simply add the schema name to alle tables, views and other objects inside your select statement?
As in select * from schema1.dual;I know that this is not what you want eventually, but it might help to find any misleading objects.
Furthermore it is not clear what you meant with: "avoided a table scan".
Did you avoid a full table scan (FTS) or was the table completely removed from the execution plan?
Can you post both plans?

Hi ,
I created the PSFT connection in 'Applicaiton connection' of Repository manager.
Also the Informatica server's tnsnames.ora should have entry for the source( PSFT database) and that of the datawarehouse.

Error in DAC 7.9.4 while building the execution plan

I'm getting Java exception EXCEPTION CLASS::: java.lang.NullPointerException while building the execution plan. The parameters are properly generated.
Earlier we used to get the error - No physical database mapping for the logical source was found for :DBConnection_OLAP as used in QUERY_INDEX_CREATION(DBConnection_OLAP->DBConnection_OLAP)
EXCEPTION CLASS::: com.siebel.analytics.etl.execution.NoSuchDatabaseException
We resolved this issue by using the in built connection parameters i.e. DBConnection_OLAP. This connection parameter has to be used because the execution plan cannot be built without OLAP connection.
We are not using 7.9.4 OLAP data model since we have highly customized 7.8.3 OLAP model. We have imported 7.8.3 tables in DAC.
We have created all the tasks with syncronzation method, created the task group and subject area. We are using in built DBConnection_OLAP and DBConnection_OLTP parameters and pointed them to relevant databases.
system set up -
OBI DAC server - windows server
Informatica server and repository sever 7.1.4 - installed on local machine and
provied PATH variables.
IS this problem regarding the different versions i.e. we are using OBI DAC 7.9.4 and underlying data model is 7.8.3?
Please help,
Thanks and regards,
Ashish

Hi,
Can anyone help me here as I have stuck with the following issue................?
I have created a command task in workflow at Informatica that will execute a script in Unix to purge chache at OBIEE.But I want that workflow to be added as a task in DAC at already existing Plan and should be run at the last one whenever the Incremental load happens.
I created a Task in DAC with name of Workflow like WF_AUTO_PURGE and added that task as following task at Execution mode,The problem here is,I want to build that task after adding to the plan.I some how stuck here , When I try to build the task It is giving following error !!!!!

Hi,
Go To Views -> Design -> Subject Areas tab and select your Subject Area.
Upon selecting the subject area, in the lower pane you will find Tasks tab. Click on the task tab, there Add/Remove button will appear.
Click on the Add/Remove button, one dialog box will be shown and in that click on the Query button and enter task group name *"TASK_GROUP_Past_Due_Cost"* and click on go button.
Once that task appears click on Add button and click on the Save button.
This will add that particular task group to your subject Area. Once these steps are done build the execution plan and start the DAC load.
Hope this helps....
Thanks,

I was trying to get an explain plan for below query. (Refer - A)
BILL_DETAIL table have index of ZONECODE,MRNO,AREACODE,WCNO but still it's
showing 'TABLE ACCESS FULL in BILL_DETAIL'
If i select only first 4 column, it is going by index. (REFER - B)
As per my knowledge index will consider only where clause conditions
but here I couldn't understand why this considering select output columns.This is because Oracle is smart enough to know that the entire query can be satisfied by using the index without hitting the table. However, once you add a column that doesn't exist in the index Oracle has decided it is more efficient to use the full table scan.
I also noticed that all the row estimates are 1 in the execution plans. Is this expected? If not, have statistics on the relevant objects been gathered?
Generally speaking, when you have a query tuning question providing information in these threads is extremely helpful:
{message:id=1812597}
{thread:id=863295}
Additionally, when posting query plans, queries, or any code please use \ tags to preserve formatting.

Not only queries are different but also the number of blocks read by top 10 queries are much higher on 17th than 18th.
The other big difference is the average read time on two days

You wrote with different execution plan, I think, you saw plans. It is very difficult, you get old plan.
I think Execution plans is not changed in different days, if you not added index or ...
What say ADDM report about this script?
As you know, It is normally, different Elapsed Time for same statement in different day.
It is depend your database workload.
It think you must use SQL Access and SQl Tuning advisor for this script.
You can get solution for slow running problem.

Missing images in html export of execution plan

Hi %,
I need to print a rather long execution plan and for this purpose I exported it to html. But unfortunately the little images are missing, which is not soooo bad, but when I distribute this to our developers it just looks better. I've searched the whole disk, but didn't find them. Can someone please help me? Where is the trick? btw: Version 2.1.0.63
best regards
Andreas

You can request this at the SQL Developer Exchange, so other users can vote and add weight for possible future implementation.
