37.0. "Problem with access data source with PowerMart" by NEWVAX::EBARON (Evelyn Baron) Tue Apr 08 1997 22:09

I have PowerMart up and running in our client/server lab.  
I have loaded the tutorial database into an Oracle DB on a Unix system and
I have a repository and subject area created on an NT (SQL/Server) server.
I go into Source Analyzer/Analyze/Select source definition for Analyzing.
I select Oracle and enter the information for the ODBC data source I set
up for the Oracle Db (which I know works because I can get to the Oracle
data from MS Access).  I then get the error message, "There are no source
tables at the specified connection."

Does anyone have any idea what the problem is?  I can't find anything listed
in the documentation.
Thanks for your help.
Regards,
Evelyn

Evelyne,
Probably it's the table owner name.
In the source anayzer, it promts you for the username/password combination, but
also for the table ownership. This depends upon the creator of the tables, and
whether they can be seen through the username/password combination.

Try 'select tablename, owner from dba_tables' in oracle to find out the owner.
(could have the field & tablenames wrong there... but it's something to that
effect).

37.2Ownership is OKNEWVAX::EBARONEvelyn BaronWed Apr 09 1997 17:2513
Rob,
I verified the ownership of the tables and it is the one I expected 
(DOE_ADMIN).  I created the tables using the Warehouse Designer in the 
PowerMart designer, using the same connection that I am trying to use 
with the Source Analyzer.  

I have also created the tutorial tables in the SQL/Server database and 
tried to perform the Source Analyzer and I get the same error.

Any other ideas?
Evelyn


37.3Is this what you did?HERON::ROWLANDSRob Rowlands @vbo 828 5480Thu Apr 10 1997 11:4713
Let's see,
You manager to create tables using the Warehouse designer:
 - create table & fields
 - fields; 
 - generate SQL
 - Execute SQL (were there any errors?)) 

and you still can't see these tables through the source analyser, 
with the same connection information as you supplied with the 
Warehouse Designer 'Execute SQL' ...?

(Note, you wouldn't normally want to source-analyse warehouse-designer tables,
but it's a good way of testing general connectivity issues)
37.4I'm using Informatical supplied scriptsNEWVAX::EBARONEvelyn BaronThu Apr 10 1997 17:2415
The tutorial comes with scripts to create and populate tables in a 
database.  If you have a copy of the installation guide, the tutorial 
installation is described on page 17.  Running the tutorial is described
in Appendix A of the Designer's Guide.  The scripts provided create the
source database.  The Warehouse designer option to Execute SQL for 
Warehouse Table Creation is used to create and populate the source 
database. 

It is puzzling that the same connection is used to create the source
database cannot read the database. Do we have an Informatica technical
contact here in the US that I can call?

Thanks for the help,
Evelyn

37.6more info neededHERON::ROWLANDSRob Rowlands @vbo 828 5480Wed Apr 16 1997 16:0312
Evelyn,
Could you tell me:
1) under which username/password  you created the tables;
2) what you see the ownership as in the database?

There isn't any magic anywhere, it really must be a question of
username/ownership. I just went through the exercise with a German colleague
who was seeing a similar problem, and he fixed the issue by creating the tables 
under a username other than SYS / SYSTEM.

I've just been through the Oracle 7.3.2 workgroup installation, and can try to
reproduce what you did...
