Change Capture Process DAC

Hi,
I;m using the out of the box execution plan in DAC for data load (CRM Complete - Siebel 8.0).I'm trying to implement the change capture process.I've created the trigger on S_ORG_EXT table as described in the DOCS.
Whenever records are deleted from the base table S_ORG_EXT the should also be deleted from the w_org_d table of the warehouse..i'm i right?
My issue is the deleted records are inserted in the S_ETL_R_IMG_26 & the S_ETL_D_IMG_26 TABLE & are also getting deleted from the W_ORG_DS (staging table)table but are not getting deleted from the w_org_d table.
Can any one suggest what could be the reason??Do i need to do any other configuration in the DAC Interface.
Thanks & Regards,

1.) Wrong forum. Go here: Business Intelligence Applications
2.) Soft delete or hard delete? Sound to me like you want to get rid of teh records. I.e. deleting history.
3.) Normal upsert mapping swon't do, you'll need delete mappings (depending on #2)

How to Change the Change Capture and Sync Process in DAC 7.9

Hi,
I would like to change the scripts that is involved in the change capture process , particularly the ones that has the siebel asset tables and organization tables.
I am not able to see any editor to change the scripts that involves in building the image R and I tables. Please guide me through this,.
Regards,
Madasamy

That is not suggestable to changing for OOB tables, if you want to go with your own process then create a new task and apply your changes
If you want you can go with ebs kind of process which follows last refresh date with LAST_UPD
instead of the below Siebel process
For Full
INSERT INTO S_ETL_R_IMG_6
     (ROW_ID, MODIFICATION_NUM, LAST_UPD)
     SELECT
          ROW_ID
          ,MODIFICATION_NUM
          ,LAST_UPD
     FROM
          S_ASSET
     WHERE
          LAST_UPD > CONVERT(CHAR, '2012-10-07 13:02:09', 120)
For Incr
INSERT INTO S_ETL_R_IMG_6
     (ROW_ID, MODIFICATION_NUM, LAST_UPD)
     SELECT
          ROW_ID
          ,MODIFICATION_NUM
          ,LAST_UPD
     FROM
          S_ETL_I_IMG_6
DELETE FROM S_ETL_R_IMG_6 WHERE LAST_UPD < CONVERT(CHAR, '2012-10-07 13:02:26', 120)

Using DAC for implementation of two change capture views on same base table

Hello
We have a need to create 2 views (V_INS_CLAIM & V1_INS_CLAIM) on a single table (S_INS_CLAIM) using DAC & Image tables.
The V_INS_CLAIM will be used to load ODS on a hourly basis and
The V1_INS_CLAIM will be used to load DataMart on a daily basis.
For this purpose, we propose using the following approach:
1) Create 2 separate containers - one for ODS and one for Datamart.
2) Use a separate image table suffix (for the same table) on each container e.g.
- Use image suffix 51 on S_INS_CLAIM for the ODS container (will result in image tables having suffix 51)
- Use image suffix 61 on S_INS_CLAIM for the Datamart container (will result in image tables having suffix 61)
3) In the ODS container, the change capture process would create a view V_INS_CLAIM using
the base table S_INS_CLAIM and the I/R/D tables using image suffix 51
For this folder the 'Drop and Create Change Capture Views Always' flag will be set to True
All views for this container will be created with the prefix "V_"
4) For the Datamart container, we propose to set the flag 'Drop and Create Change Capture Views Always' to False.
This would ensure that DAC never drops/creates the view (assuming that the view was already created by the ODS container)
For creating the change capture views, we propose to create the views using sql procedures.
All views for this container will be created with the prefix "V1_"
The above procedure would ensure that we have distinct views created for each target (ODS & Datamart), which are refreshed at different intervals.
Alternatively, instead of creating 2 views with different names in the SIEBEL schema,
we could create 2 schemas - one for ODS and the other for Datamart and create the change capture
views separately in each schema (using separate I/R/D image tables - as mentioned above).
Please let me know which of the above 2 approaches would work and supported by DAC and which would be the better option ?
Thanks

Problem with change capture

HI,
we've a problem with the Change Capture in the DAC's Execution Plan.
We've cretead a new data model but we want to reuse the image table and the Change Capture process, so we've perfomed the following step:
1) create the mapping SDE e SIL for the new tables of datamodel in Informatica Power Center
2) register these mapping in the DAC
3) create a subject areas and associate these tasks to this
4) create execution plan including "change capture" and "change capture sync"
5) execute our "execution plan"
the problem is the following:
from the Execute -> Current Run Tab -> task
we can see that execution time of change capture is 0
from the Execute -> Current Run Tab -> task details
there aren't any change capture details
So, our image table are empty.
Do you have any idea?
Thanks in advance,
Antonello.

HI Antonello,
I am also having the same issue like you. I have created a new execution plan in DAC 101341 and ran it. It seems like the task Change Capture For Siebel OLTP completed in 0 seconds and there are no details for that particular task. Can you please let me know if you have resolved this issue? Your help is much appreciated.
Thanks

Change Capture For Oracle EBS Sources

Hello,
I am trying to understand how the change capture process happens in DAC.
For Siebel sources, I understood that it happens through 'image' tables. And there are some docs/info available on this.
I am just wondering how this happens in case of Oracle EBS and other sources. I think there is no image table concept with these sources.
Can anyone point me to some info on this..?
Many Thanks..!

Yes, for EBS, PeopleSoft and other non-Siebel sources, the change capture process is usually based on a form of "LAST UPDATE DATE" on the source system tables. This is is usually compared against the "LAST REFRESH DATE" in the DAC for the source and target tables. This can be seen if you look at the Session overrides for the FULL versus INCREMETAL workflows/sessions. Of course, this process may differ based on the nature of the source system. I believe certain sources that do not have a useable "LAST UPDATE DATE" may require a full extract each time. The best approach would be to go through the vanilla ETL code for FULL versus INCREMENTAL sessions.
if this was helpful, please mark the answer as correct.

Change Capture For Siebel OLTP task in DAC running for more than 10 hours

whole etl load used to complete in 2 hours (as on now siebel data having sample data). since last Friday Change Capture For Siebel OLTP task in DAC execution plan running for more than 10 hours. I am not able to trouble shoot the problem because no log for this task
what could be the reason for this problem? how can I fix that problem?
Appreciate your help
Thanks
Jay.

Which ETL is it that is taking the longest (is it an SDE, SIL, PLP?). I have seen someOracle vanilla ETLs coded in a way that is very ineffective. Check the DAC and Informatica logs and find out which mapping it is and where the delay is (e.g. SQL, write to DB..etc).

Thanks Srini,
Sorry we have patched all our environments with following patch.
Dac Build AN 10.1.3.4.1.patch.20110427.0538, Build date: April 27 2011.
If i have to apply the new patch. i have to do it in all environments.
Its working in all other environments except one having problem.
Anyway I have re-installed DAC and it fixed the problem. I dont know what caused this problem.
Its shame that i have to re-install it, this is not recommended, this is not best practice.

DAC Change Capture for Siebel OLTP - Customizing Change capture queries

h4. I want to change the OOTB Change Capture SQL for few of the siebel OLTP base tables , basically want to include some parallel connection details into it. Also the same for Change Capture Sync with Siebel OLTP.
h4. I think its not possible to achieve this through ChangeCaptureFilter.xml or Custom.SQL from the DAC server backend. I couldnt change the sqls that are available in DAC Console too. SO is there any other places out there to do this customization ?
h4. Please let me know if anyone have come across such a custom.

Oralce streamsSystem Change Number (SCN) and capture process

Do we have get SCN before capture process is started ? If yes , from where does the replication is started .
WIll replication process startright from the time when SCN is captured
OR
will replicaion start from the time when the capture process is started
Edited by: [email protected] on Mar 26, 2009 6:04 PM

I am trying to setup oracle streams to enable replication for a set of tables.
One of the step as per the doc is is to setup/get SCN and its acheived by the following peice of code.
CONNECT STRMADMIN/STRMADMINPW@<CONNECT_STRING_SOURCE>
DECLARE
V_SCN NUMBER;
BEGIN
V_SCN := DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();
DBMS_APPLY_ADM.SET_TABLE_INSTANTIATION_SCN@DB_LINK_TARGET_DB(
SOURCE_OBJECT_NAME => '<SCOTT.EMP>',
SOURCE_DATABASE_NAME => 'SOURCE_DATABASE',
INSTANTIATION_SCN => V_SCN);
END;

HR Analytics Change capture logic

Hi All
My customer currently has a custom built warehouse and is using obiee as the reporting tool.
I am busy implementing 7.9.6.2 apps for them from their EBS 12.1.1 instance.
They have a burning issue which is that in their source system, the users do not always capture the fields required for their compliance reports, so their headcounts are not correct, then the users correct the data and the BI headcounts historically are not correct.
I have suggested that this problem must be dealt with in the source system, but they want to find out if the pre built apps will offer any relief.
The question is how does the BAW change capture work surrounding this scenario?
I have said that from what I have experienced the change capture works with the refresh dates in the DAC and that any changes will be picked up by the last updated date and an update will be effected to change the data.
This is unless there is SCD type logic built in where the snapshots will reflect the history as it was and perhaps only the aggregates will be effected.
I have been checking the employee headcount in the rpd and following the process back to the SDE_ORA_PersistedStage_WorkforceEvent_HeadCount_Full where the data is extracted from the source and there is a lot of headcount logic built in but I cannot work out for sure how the net changes will be handled.
Is there anyone who has had experience with HR Head count snapshots and aggregations being affected by back dated source system changes?
Regards
Nick

Hi Tarik
Thanks for the info, I have generated the flex field and configured the csv's, I am stuck at this stage with the similar issue to the 'Error in SDE_ORA_AbsenceEvent_Full workflow' post in this forum and have an sr logged on metalink so I cannot actually test the behaviour.
The customer wants to know what will the result be if they backdate a change specifically around headcount and compliance fields in the source system when the pre built hr etl's run. They want to know if it will update the warehouse and how will the snapshot tables be effected.
I followed from source to target on headcount as a metric;
on a high level this is what I understand about the process:(corrections welcome)
SDE_ORA_PersistedStage_WorkforceEvent_HeadCount_Full loads W_ORA_WEVT_HDC_PS (stores a history of headcount)
Then SDE_ORA_WorkforceEventFact_Hdcnt loads W_WRKFC_EVT_FS
then
SIL_WorkforceEventFact loads W_WRKFC_EVT_F with the update strategy in Upd W Wrkfc evt f ins upd identifies from comparing the etl proc wid & data source num whether there will be an insert update or delete.
If there is a change it inserts a new record and marks the old one as delete with the soft delete logic.
The the rpd looks at alias's of w_wrkfc_evt_f with joins to ago keys for history and to current for up to date records.
So assuming the changes do not fall out side of the dac's prune days, and the 'back dated' change is picked up in the etl by the OLTP ' last updated time stamp' being later then the etl refresh date, will the behaviour be that the records are updated but the snapshots remain unchanged and therefore reflect the incorrect data?
For example. A person joins the organization in Jan, but there current system report does not reflect him because the record does not have the mandatory fields correctly filled out and he falls into an exeception report. In Feb the data is not corrected but in March the HR team correct the data and back date the change in their system to January.
How will this affect the headcount in the BAW? How would the BAW handle this scenario? Is the question from the client ( assuming the ootb values are correct and in use.)
I have said I think the dac will pick up the last upd, load the tables above and update the total so it is showing correctly, looking back at the snapshot should refelct the correct data because the BAW will have picked up the join 'Event' off PER_ALL_ASSIGNMENTS_F unlike their bespoke system which uses per all people f.
If there are any HR gurus out there who can confirm my expectations or offer any comments I would appreciate it.
Many thanks
Nick

HOW CAN I GET MY CHANGE IN PROCESSING(got it)?

Hi all....
   please understand my requiement and get back with your valueble answers...
iam having one table control in one of my screen....
in that....table control it contains three fields.... so as we know three columns...
middle column is for second field...
here i am changing first entry ( 1st row of second column) manually... and clicking one push button of my screen to do some caluclation part combine with table control entries...
ex: table controls looks like.....(before)
     1   100 ab
     2   200 gh
     3   300 vf
     4   400 fh
     .. .... ...... etc
now manual i changed above like....(after)
     1   150 ab       <------ only change
     2   200 gh
     3   300 vf
     4   400 fh
     .. .... ...... etc
So... here my problem is iam getting my caluculation part with that field as 100 only.... not as 150,
even i debug this variable with defferent conditions like......
   READ TABLE ITAB WHERE ITAB-F1 = 1.
SO HOW CAN I GET MY CHANGE IN PROCESSING? WHERE I HAV TO MODIFY MY PROGRAM?
(edited: prevoius ly this value is capturing correctly...because that calculation part is in the module which is added between chain and endchain)
Expect Max marks,
Thanks,
Naveen

dont worry guys i got the answer.... we have to catch that varible in the chain and endchain operater.... by using module.....
thank you all...

Hi,
I think f2 is a key field in table.So 150 considered as new entry.this case you have to keep 100 for delete from table then add 150 entry.i think you are getting update in itab.But not in table.If you are not getting itab, post your code to check

Changes to process chanins not imported

Hi experts,
I am making some changes to process chains (BI7) like removing a step or adding a step like activating an ODS. When I created a transport by activating and imported to the QA system, the changes are not imported correctly. For the new process type, the process variants are captured in the transport.
I
n 3.0b. whatever change I make in the process chain is automatically captured when I activate the chain. however, in BI 7, this seem to behave differently.
Can anyone advise if this is the case or is this due to some incorrect settings?
We have just installed BI7.
Thanks
KS

Hi KS,
normally the changes should be collected if you click the transport connection button and grab the changes into a request - this is the way I have been supposing.
If this doesnt work you can try to assign the chain to a request directly in the transport system. Mark a request e.g. in SE10, then click in the menu 'Include objects...' > 'Freely selected objects' > Radiobutton 'Selected objects' > input type 'R3TR RSPC' with free slection ( * ). Finally, mark the chain you want to assign and press F9 in order to include it.
Please send me a feedback about the transport result with both of these methods.
Thanks + regards,
Balint

Instantiation and start_scn of capture process

Hi,
We are working on stream replication, and I have one doubt abt the behavior of the stream.
During set up, we have to instantiate the database objects whose data will be transferrd during the process. This instantiation process, will create the object at the destination db and set scn value beyond which changes from the source db will be accepted. Now, during creation of capture process, capture process will be assigned a specific start_scn value. Capture process will start capturing the changes beyond this value and will put in capture queue. If in between capture process get aborted, and we have no alternative other than re-creation of capture process, what will happen with the data which will get created during that dropping / recreation procedure of capture process. Do I need to physically get the data and import at the destination db. When at destination db, we have instantiated objects, why not we have some kind of mechanism by which new capture process will start capturing the changes from the least instantiated scn among all instantiated tables ? Is there any other work around than exp/imp when both db (schema) are not sync at source / destination b'coz of failure of capture process. We did face this problem, and could find only one work around of exp/imp of data.
thanx,

Thanks Mr SK.
The foll. query gives some kind of confirmation
source DB
SELECT SID, SERIAL#, CAPTURE#,CAPTURE_MESSAGE_NUMBER, ENQUEUE_MESSAGE_NUMBER, APPLY_NAME, APPLY_MESSAGES_SENT FROM V$STREAMS_CAPTURE

One more question :
Is there any maximum limit in no. of DBs involved in Oracle Streams.

Capture process: Can it write to a queue table in another database?

The capture process reads the archived redo logs. It then writes the appropriate changes into the queue table in the same database.
Can the Capture process read the archived redo logs and write to a queue table in another database?
HP-UX
Oracle 9.2.0.5

What you are asking is not possible directly in 9i i.e. capture process cannot read the logs and write to a queue somewhere else.
If the other database is also Oracle with platform and version compatibility then, you can use the 10g downstream capture feature to accomplish this.
