Source Database.

Hi All,
I am using owb builder client 9.0.2.56.0 and owb builder repository 9.0.2.0.0 on windows NT env.
I understand owb allows to select data from sap, flat files or thru oracle database tables thru integrator.
However after browsing this forum many users posted messages for querying selection of data from other sources, i am wondering is it possible to select data from other database e.g. Informnix, SQL or Sybase or is it new version of OWB will provide this feature ?
Thanks in Advance.

You will also need to purchase ODBC drivers for the specific database that you want to access. In other words, you will have to configure something like this:
Oracle DB -> generic ODBC Layer (provided by Oracle) -> specific SQL server ODBC layer (to be purchased by the user) -> SQL Server DB
Radomir is correctly pointing out that you will have to create database links traversing the above mentioned architecture.

Locks made against source database (SQLServer 6.5 to 9.0.1.2 migration)

I was wondering if there is any information about the types of locks that OMWB will take out on the source SQLServer database in a migration. From what I can tell these locks occur on the source database while the table data is loaded in to the target Oracle database. Are they taken at any other time during the migration process? How does OMWB determine what locks to take?
I need to migrate several production SQLServer 6.5 databases and I need to understand how OMWB will perform locks so I don't bottleneck our production SQLServer databases while they are converted to Oracle. Most of the migration work will be performed off hours, but I still would like some insight into the locking. In a related question, how does OMWB maintain consistency between tables during the migration process?
Thanks in advance for your help.

Hi,
You will be able to migrate from 6.5 to 9.3.1, if the 6.5 version is on a seperate server from the planned 9.3.1 version then you can use the migration wizard to do so.
If you want to migrate users and groups make sure the 9.3.1 version is still in native security mode, otherwise you will need to use esscmd/maxl to extract user information and then import.
The migration wizard will not take the data so you should really export that from your source.

Source database in NOARCHIVELOG temporarily for maintenance

Hi all,
We have a big maintenance to run next week end. There will be mostly index rebuild, statistics gathered and so. We are using 10.2.0.3. Source database is a RAC one.
We would like to put our database in NOARCHIVELOG temporarily during this maintenance windows. This may sound like an easy task, but i rather consider it as a risky one - I need a 100% safe procedure!!
I wonderer, if there is arcticles in Oracle documentation or Metalink that could help.
I think I know several of the steps required:
- Stop the capture
- Put the database in NOARCHIVELOG mode
- Re-instantiate the tables using dbms_capture_adm.prepare_table_instantiation on the source database
- Ré-instantiate the tables using dbms_apply_adm.set_table_instantiation_scn on the destination database
- I think I will have to advance the SCN on the capture but I'm not sure if I have to change the FIRST_SCN or the START_SCN or both?
- Put the database back in ARCHIVELOG mode
- Start the capture
I'm not sure in wich order i have to do these tasks.
Thank you for any advice/link on that subjet!
Jocelyn

Thanks a lot Rijesh for your response,
In the meantime, I do my own search and came to the same conclusion.
I also experimented with note 471695.1 on Metalink (Required Steps to Recreate a Capture Process). It "almost" works! It recreates the capture correctly, but it does not carry the existing table rules... (the content of DBA_STREAMS_TABLE_RULES before dropping the capture).
So it's probably going to be much easier to recreate the whole thing from scratch (we have an existing procedure that is very mature).

Why am I getting 'Unable to signon to the Source Database.' just prior to 'Running the DBTSFIX Report' step.

We are upgrading from Tools 8.53 to Tools 8.54 in HCM. I am receiving logging event 'Unable to signon to the Source Database.' just prior to 'Running the DBTSFIX Report' step. I found case 1545297.1 where it said to choose initial move as opposed to move

For Tools only upgrades, while creating the jobs, you should choose 'Initial' and not 'Move to production'
An excerpt from http://docs.oracle.com/cd/E56736_01/psft/acrobat/Getting_Started_on_Your_PeopleTools_Upgrade_08_2014.pdf is given below
MTP indicates that this step runs only in Move to Production upgrade passes. The step is not applicable to the initial pass. This is not applicable for PeopleSoft PeopleTools-only upgrades.

The 'Third Party Connections' drop down box on the 'Source Database' step in the Migration Wizard is empty.

Here are the environmental details:
SQLDeveloper 32-bit Version 3.2.20.09 (Build MAIN-09.87)
Oracle Database: 12C single instance (no RAC)
Oracle client: 12C 32 bit
Windows 64 bit desktop
I am attempting to migrate an MS Access application to Oracle. I pick the ‘Migrate’ selection from the ‘Tools’ Menu SQL Developer. This puts me into the Migration Wizard. When I get to the ‘Source Database’ step of the migration wizard, the ‘Choose the Third Party database from which you are migrating’ drop-down box is not being populated with the current available connections. It is empty. If I type a valid connection name into the box, SQL Developer takes it on this screen but does not keep it for the next screen/step. It has no persistence. I even tried to make sure that each connection was open/connected before beginning the migration process.
Due to the fact that I am attempting to migrate an MSAccess application, I am mixing 32-bit and 64 bit software. This may be the issue as to why the drop down is losing addressability. I have not applied any patches to this version of SQL Developer.

Hi,
If you need easy way to migrate Microsoft Access to Oracle probably it is more reasonable to review some tools specially designed to this purpose. For example:
Access to Oracle converter by Intelligent Converters
Access to Oracle converter by SpectralCore
Access to Oracle converter by Interface Computers
Hope, this will help.
Sincerely,
Vlad

Multiple source databases

Hello,
I need to load data into dimensions and cube from multiple source databases. We have separate transaction databases for each country, but data must be loaded into common target schema. At the moment we have created mappings which loads data from one source database.
What is the best way to populate, for example customers dimension from customers transaction tables (located in multiple source databases) if business identifiers can overlap?

I would break this up into two pieces: the load from the source systems into the staging area, and then the load from the staging area into the target table, which you mentioned was a dimension.
There is no reason you would have to use views or synonyms if you don't want to. You could approach this either with a SET operator, in this case a union, that brought all the sources together into the staging table. However, I would likely create multiple mappings for each source system. I would create a mapping for each table that you have to pull data from, and then create a separate process flow that controls all the tables being pulled from a particular source database. This allows you to schedule the extractions from the source systems independently of each other in case they need to run at different times. The end result of all of this will be a series of staging tables that are loaded from source tables from all the different locations. For each of the singular mappings, I would create a constant that defined the source of the data for this mapping, and load that constant into a column called SOURCE_SYSTEM, or perhaps COUNTRY, as you mentioned. Then, this SOURCE_SYSTEM/COUNTRY column + SOURCE_SYSTEM_ID would serve as the natural key.
You can choose to persist these tables (as an ODS of sorts) or not... that is up to you and your requirements.
Finally, I would create a single mapping that loads the final target table from the single staging table.
Let me know if this doesn't make sense.

Stewart Bryson

ADF (View Object) with open source database

Hi all,
Recently, I am evaluating JDeveloper 9.0.5.2 ADF with an open source database (Firebird).
I follow the instruction to:
1. Create an entity object
2. Create a view object for the entity object in 1
3. Create an application module for the view object in 2
4. Right click on the application module and test -> all worked fine
5. I created a jsp and drag the view (in 2) to it from Data Control Palette
6. Test it in OC4J -> an error occurred (not because of jdbc config)
JBO-27122: SQL error during statement preparation. Statement: SELECT * FROM (SELECT Department.DEPT_NO, Department.DEPARTMENT AS DEPARTMENT1, Department.HEAD_DEPT, Department.MNGR_NO, Department.BUDGET, Department.LOCATION, Department.PHONE_NO FROM DEPARTMENT Department) QRSLT ORDER BY DEPT_NO
GDS Exception. 335544569. Dynamic SQL Error SQL error code = -104 Token unknown - line 1, char 16 SELECT
To my knowledge, the error should be due to Firebird doesn't support the query syntax " select * (select col1, col2... from table) QRSLT where... order by... "
I am quite headache as this query is automatically generated by JDeveloper. I am figuring out whether I can change it. It seems that I have to play with the ViewObjectImpl class.
I do think ADF is an amazing technology. However, is it only so amazing with the Oracle technologies? Please correct me if I am wrong.
Hons

Dear Shay Shmeltzer,
Thank you for your reply. After hours of trying on Firebird, I still get the error:
JBO-27122: SQL error during statement preparation. Statement: SELECT * FROM (SELECT Department.DEPT_NO, Department.DEPARTMENT AS DEPARTMENT1, Department.HEAD_DEPT, Department.MNGR_NO, Department.BUDGET, Department.LOCATION, Department.PHONE_NO FROM DEPARTMENT Department) QRSLT ORDER BY DEPT_NO
GDS Exception. 335544569. Dynamic SQL Error SQL error code = -104 Token unknown - line 1, char 16 SELECT
I then downloaded the MySQL 4.0 and install on my system to do the exact procedures. No error! Thing works fine! Oh man...
For the Firebird case, a strange thing to note is that the data table (I dragged) contains data, but the error message is on top of it.
Actually, I don't have a particular database preference but I do hope ADF can work equally for these open-source databases. I think the problem may also be contributed by Firebird. Hope that I can figure it out this week.
Regards,
Hons

SQL Server 2000 to Oracle 9.2 problem [b]"Source database not captured"[/b]

hi, first-timer here working with the latest omwb version.
anyway
i'm trying to do a offline migration of the "Northwind" demo database as an example, they are no problems with the process, everything works like a charm ... until is time to press the "finish" button in the wizard-summary screen.
after that the output seems normal and there's no error, the completion pop-up message throws a 0 warnings 0 errors, supposedly ending the loading of the model, but the capture is labeled as aborted and the source database is not captured at all.
i have done everything in the manual, creating the privileged user "omwb_user", seeing that the corresponding tablespace was created, giving enough space everywhere.
so, what's the problem here?
i will appreciate any help or hint
thank in advance

i thought that mi domain standard of "john.doe" was the problem, i take out all the users, and now there is only the "sa" and "guest" accounts.
tried the online capture and it worked completely, tried the offline, the same problem:

Streams Replication:Source database Physical or Logical Standby DB

Can the source database in streams replication be a physical or logical standby database ? If so, is the process of configuring streams the same as a regular database ? Are there any best practices or different configuration if the source is Logical or Physical standby DB ?
Thanks in advance.

Never done it, but I don't see any reason why it should not work.
Streams, at capture site, is only a data dictionary game and in a logical standby your data dictionary is open read write.
Streams, at capture site, never touch the source tables, in fact they may even not exists from Streams point of view,
as it deals only with the redo that are generated.
So Streams horizon is limited to the data dictionary, the log buffer, the archives and, in SYSAUX tablespace, all the LOGMNR_% tables. All these structures are read write in the logical standby. However, for the capture/propagation you may have to set to true the 'include_tagged_lcr' parameters.

Columns mismatch between Source database and Source in Informatica

Hi,
I'm trying to create few columns into the datawarehosue tables. I can see the columns in my source system (Siebel CRM) in toad. When I access the source table via Informatica Powercenter Designer. I don't see that column in the source tabel. I have a doubt that whether I'm connecting to the right source database from Informatica. How do I check this and change this? The column which I'm looking for in the source system is not custom column. Its Siebel out of the box column. Could any one provide more information on this.
Thanks in advance,
Ravi

You may have to reimport the table from the Source Analyzer workspace. When you import, make sure you are pulling from the correct source database and schema.
Informatica does not automatically update the table definition if the source changes.

Changes in Source Database.

Hi All,
OWB Config Details is as follows.
OWB ver 9.2 with Windows NT
Oracle 9i.
In near future we are expecting changes in source database i.e. source database from existing will change to a new database which may be same or different.
The level of changes identified are as follows.
Table Name Changes
Column Name Changes
Business Logic Changes
View name changes
I guess there will be changes in other parameter like ip address,sid, dblink ..etc.
I knew in OWB 9.0.2.56 column level changes can be incorporated by re-importing the table & adding,modifying or deleting the column & by selecting in-bound / out-bound reconcillation option in mapping editor. I would like to know is it the same way we need to do in OWB 9.2 version or is there any better way or utility which can ease this task?
As per my knowledge we will need to do it for each & every mapping & in case of business logic change, we will need to recreate the mapping.
Can someone help me in this?
Thanks in Advance.
Regards,
Vidyanand

Hi Igor,
You are talking about simplifying matters when there have been changes in the source, and that that is going to be in the release of Q2-2004.
Which release might that be and - since it is already mid september - is it already 'on the market'?
What I'm looking for is an 'easy' way to incorporate changes in source objects in all mapping objects that are not database objects.
So far this has always been a manual job, since only DB-objects can be reconciled. If you have a very big mapping with a lot of objects between source and target DB-object, this has proven to be extremely time-consuming, since all objects have to be opened and the attribute properties of altered columns manually adjusted to the new situation.
Is this wat you are talking about that is going to be greatly improved?
If not, what would be the best approach for these sorts of operations?
Cheers, Patrick

Is mysql a free open source database or do you need a license for it in prd

is mysql a free open source database or do you need a license for it in production.

Hi,
It should be free under GPL (General Public license).Usually it will comes with your operating system distribution (eg:RHEL)
If you download it from Oracle site, it should have the commercial license tied to it, and you need to pay for that if it is in use for production.

ORA-26687: no instantiation SCN provided for ... in source database ...

We are testing streams on Databases between our Main and Branch Campus. We set up the Capture, Propagation and the Apply for the databases and receive the error on the Apply process when doing an insert:
ORA-26687: no instantiation SCN provided for [TABLE] in source database [DATABASE]
We are running Oracle 10.2.0.2.0
Thank you in advance for your help.

At source, execute the following as strmadmin
SELECT * FROM DBA_CAPTURE_PREPARED_TABLES;
Get the SCN for the correspoing table and use at destination
At destination:
BEGIN
DBMS_APPLY_ADM.SET_TABLE_INSTANTIATION_SCN (
source_object_name => 'schema.tablename',
source_database_name => 'global db name of source',
instantiation_scn => &iscn);
END;
Enter iscn that you got at souce.
Retry the error. This will work.

Source database version dependency

Hello community,
While running execution plan for "Procurement and Spend only analytics" in DAC we are getting the following error on one of the Informatica workflow - SDE_ORA_PurchaseReceiptFact_full.
"From keyword not found where expected".
AFter investigating further, we found that the following function is not compatiable - CONNECT_BY_PATH with our source database(Oracle 9i / EBS 11.5.10.2).
Just want to if anyone who has implemented OBIEE / BI Apps 7.9.6 with Oracle 9i / EBS 11.5.10.2 has the same problem and if yes, how did you resolve the issue.
Thank you

Hi
I always used Ultra Search with the Enterprise Edition. But, since it isn't an option, it should be available in the Standard Edition as well. Also in the documentation, especially http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96531/ch5_edit.htm#90217, there is no mention...

HOW TO SOLVE THIS PROBLEM?

I cant see any join conditions in your query posted. Whats the purpose of the query above. It will just bring you a cartesian product (cross join) of tables involved subjected to filters. Are you sure this is the correct query?
The error you're getting may be because you've not yet populated DimProduct or may be because of logic you used in popultaing DimProduct causing it to miss some records which is what query is referring to in above case.

Informatica Workflow not able to connect to source database.

Hi,
I have completed the installation of OBI Apps.All the test connections are working fine and I have also configured the Relational Connection in Informatica Workflow.The passwords,username and connect string are correct.Still when I run a ETL all the tasks that need to connect to source database fail.I checked the session logs of those workflow and it gave me following error:

From DAC I am able to connect to the databases.There seems to be some problem in the relational connections.What are the drivers involved and where should they be installed.
Please help.
Thanks and regards,
Soumya.

Hi,
I think you need to check you connections in the Work flow manager. So, i'd suggest you to follow this below section again. Your error clearly shows that there is problem with the connections.
"4.13 Configuring Relational Connections In Informatica Workflow Manager" in Installation & Configuration guide.
Post back here, if you find any problems.
Thanks,

Source Database.
