Implementation plan of DAC
Hi all
I'm new to the DAC. I have a new domain with tasks for the new fact and dimension tables custom. Now
I have to add this new already existing domain of the execution plan that allows to launch at full load.
My question is when I add this new plan already existing domain running and when I build it he will be
set the order of tasks with the new tasks that are there in the new domain or do it automatically
I need to assign order of discipline before adding to the execution plan.
Also can someone help me how can I give order to the tasks of discipline as to run the first mapping of SDE and run the mapping of SIL.
I have created groups of tasks, but I don't know what I should add to plan of execution or not because I like the customized 3 dimensional mappings and
I created 3 groups of different tasks for each table.
Any help would be really appreciated.
Thanks in advance!
You don't have to do anything dac will take care of him.
Just add new domain to EP, build and run that's all.
The tables related to the new domain will be loaded as full and rest as yen

Hi experts,
I want to know, how to get the past (like a week older) sql_id/plan_jash_values and corresponding implementation plans.
I am aware that v$ session contains these last sql_id/hash_value, distinguished by a sql statement that is executed and we can get the plan_hash_value from v$ sql using the following query.
Select sql_id, hash_value, plan_hash_value from v$ sql where sql_id = & sql_id;
Once you leave this session, session $ v clears the session information, subsequently sql_id will be also deleted.
I want to know,
1 how long v$ sql holds the plan_hash_value, is there a retention period?
2. when we issue ' select * table ((dbms_xplan.display_cursor ('& sql_id')) ", when the execution plan is read since?").
3. I need to compare the implementation plans for a perticular query last week one, what are my options?
Please help me with my questions, experts.
Kind regards
Ravi K
Yes, the AWR repository is accessible by SQL queries on the DBA_HIST views. (these are the same!)
Thus, the AWR retention period applies to data in views DBA_HIST.
A SQL query that is not reported by a snapshot of the CWA would not be in the views DBA_HIST.

Some implementation plans alternative for this statement was found by searching

The following table lists these plans sorted by their average time.

The plan with hash 617797893 seems the most efficient one and is based on some specific SQL Tuning Set I ran on this time. But the note says that the plan is not reproducible. Is there anyway how can I force the SQL statement to execute the plan? The database version is Standard Edition 11.2.0.1.0

Is there a way to PL/SQL to force Oracle to re-evaluate the implementation plan
In a packaged procedure, I have sturctured of code like this:
The problem is that the first time through the outer loop, that he is on an implementation plan for the cursor from inside. But the plan, with what happens isn't the best plan for later iterations of the loop. I want to do is something like this:for rec1 in cursor1 loop -- do some calculations for rec2 in cursor2(cursor_params) loop -- do more stuff end loop; end loop;for rec1 in cursor1 loop -- do some calculations if rec1.column1 != prev_column1 then -- forget previously calculated cursor2 execution plan end if; for rec2 in cursor2(cursor_params) loop -- do more stuff end loop; end loop;http://prutser.WordPress.com/2009/04/19/flushing-a-cursor-out-of-the-library-cache/

Difference of cardinality estimate on explain plan and implementation plan
I think some of you know the 5% rule, which is explained in the note on metalink # 68992.1.
In short, this means that (with bind peeking out voltage)
It is also well explained fundamentals of the CBO by Jonathan Lewis.- c1 > :b1 : 5% of selectivity - c1 >= :b1 :5% of selectivity - c1 between :b1 and :b2 : 0.25% of selectivity (5% * 5%)
But I found a few odd cases where the 5% rule is broken DURATION estimate.
The most interesting part is explain plan watch again the 5% rule.
Why the difference?
I think that with bind peeking out, explain the plan and the implementation plan should show the same things.
(Assuming that all values of the environment are identical)
Am I wrong?
It's the long story to tell, but simple test cases will show what I mean.

-applied at the level of enforcement only when density 5 < %. When the density > 5%, he uses the density not 5%
I'm not sure it's a designed feature or a bug.
But estimates of different cardinality explain a plan and DURATION (with bind peeking out voltage) is not that desirable thing.
One's opinion on this?
Dion ChoSorry to take some time to get back on this one.
I can reproduce your results in 10.2.0.1, but the anomaly is not present in 9.2.0.8 and 10.2.0.3 and 11.1.0.6.
As Charles, the calculation has a boundary condition when a num_diistinct falls below 20
(i.e. when a value is more than 5% of the total data set - average).However, the fact that explain the plan and the run time you give estimates of different cardinality is a bug.
Everything they say, they should say the same thing at least that the introduction of the variable binding
introduced a possible type conversion or the NLS conversion feature that has changed the
calculation of the expected cardinality. In this case there is no reason why the use of links should be
cause confusion - so we can reasonably assume that it is a bug.Concerning

DEA before constructing an execution plan in DAC
Guys,
can someone help me what are the settings to do before building a performance indicator in CAD based on a new map?
I see that we need to provide some information configuartion for mappings on the Design tab.
I see below in the Design tab.
-Areas
-Tables
-Indices
-Working groups
-Tasks
-Tags configuration
-source system parametrs
-source of the system folders.
What is the order in which you must complete the above. Can you explain the steps in detail?

I'm looking on the execution plan for a query that doesn't use bind variable or a predicate that uses a literal, and yet what follows

Because I can very easy do a:explain plan for

However, I guess that plans for a DELETE and a SELECT statement must be the same, because they need to finish work on the same data, in any case...

So my question:
What affects the fact if the predicate information are displayed or not? The client is the same twice (tried with native SQL * more and Developer SQL 1.5.5).)
Any idea is appreciated, thanks in advance!

Plan implementation is the next DAC but in Informatica error
Hi all
can someone help me with this problem
I'm runining a plan of execution by DAC status is successful, but informatica, I get an error.
The error message:
TM_6193 error has occurred during the expansion of DB connection settingsTM_6193 error has occurred during the expansion of DB connection settings
Hello
Could you describe the problem a little bit?
If you run it with DAC, not the loaded data?
Maps of how much do you have in your implementation Plan?In a first time - check the relational connections in Informatica Workflow Manager. They should be identical to your physical data source connections in DAC.
It could be that useful...

What the implementation of plans to choose for 7.9.6.4 BIApps and EBS 12.1.3?
Hi gurus,
We have installed OBI 11.1.1.7.0 with biapps 7.9.6.4 (vanilla imported metadata and integration work DAC/Informatica) successfully. We are approved for these modules:
- Purchases and spend analytics Fusion Edition
- Human resources Analytics Fusion Edition
- Supply chain and order Analytics Fusion edition management
- Edition of Fusion financial analytics
The source system is EBS 12.1.3
We want to start testing some of the ETLs DAC, but we don't know which ones to choose from a long list of execution plans. Can someone provide links to the documentation or other sources of knowledge that explain that DAC implementation plans correspond to what above Application modules?
-bidays
Hello
By default execution plans will be there... but you need to create a system of source container, after the creation of container assemble these disciplines and create an implementation plan for each module you have four modules... then create four execution plans and produces parameters and build execution plans and run. If you have any doubts means let me know...
Kind regards

How can I create custom DAC execution plan
Hello
I need to create custom DAC execution plan to load data into tables. in fact schema we build with 2 custom tables Sun, 8 tables OOTB (fact and Sun). So I need to copy the OOTB existing execution plan, delete unwanted tables, stains ect and rebuild. But I do not know the exact process to do could you please provide step by step details?
We use 10.1.3.4.1 OBIEE, BI Apps 7.9.6.1 and customer DAC is on windows XP.
Grateful for your help!
Thank you

execution of multiple DAC running plan, is this posible?
Hi guru BI
is it possible to run several implementation plan in the same container?
or if we have several containers for kids free HR and finance, in this case the execution plan will be executed in each separate containers?
What are the impacts on the DAC Server?
Kind regards
KamleshWe can create multiple execution plans in a single container.
But it can be scheduled one after the other don't.
