VLD-2771 in OWB 9.2

Question

Hi...
I have installed OWB 9.2 onto 9.2.0.1 database on local machine (Windows XP). The install was fine and I have created both Design and Runtime repositories on the same machine.
I have created a new user called OWB and am using this as a source schema. In here is one view which does a simple select * from video5.products (one of the tables that come with the Discoverer video tutorial database).
I can pull this view in via my source location and I can create a mapping to a table in my target. When I deploy my table gets generated and deployed but the map reports a warning "VLD-2771: System privileges may not allow extraction from source V_OWB_VID_PRODUCT"
I have scanned OTN and can see that people have suggested to ignore this warning and proceed with the Deploy. This I did and it did deploy but it will not run. It deploys as MAP_VID_PROD_IT and so I am issuing this command:
BEGIN
MAP_VID_PROD_IT.MAIN;
END;
but when I run this I get this:
ORA-06550: line 2, column 1:
PLS-00306: wrong number or types of arguments in call to 'MAIN'
ORA-06550: line 2, column 1:
PL/SQL: Statement ignored
presumably the wrong number of arguements are caused because my target cannot read the source file into the map? However when I type: SELECT * FROM OWB.V_OWB_VID_PRODUCT it works.
Please help because I am going to a new client on Monday and am supposed to be installing 9.2. I have tried granting DBA privileges to all of my Runtimes accounts - Runtime Repository Owner, Runtime User and Target
Owner but does not make any difference.
Regards
Michael

Answer 1

You describe two unrelated issues: 1) system privileges between source and target schemas and 2) calling mappings "by hand".
1) The VLD-2771 warning is because the source and target schemas reside within the same database, which means that OWB does not generate code that uses database links. Rather, it generates code that uses the <schema>.<table> notation, which requires that select privileges have been granted to the tables in the source schema that the Mapping uses. Apparently OWB does not check wether the required privileges have been granted; it might not be able to depending on where you are deploying from.
Since you are able to select from the tables (presumably when logged into the target schema), there shouldn't be any problems with this.
2) The MAIN procedure in Mapping packages requires an argument which is a data structure defined somewhere else. You will have find out the type name and wether it is a PL/SQL record. I can't remember what the type name is called, but I seem to remember that it is a PL/SQL record. If it is a PL/SQL record, the code below should do the trick.
declare
map_param <type name goes here>;
begin
map_vid_prod_it.main(map_param);
end;
There is no need to specify values in the data structure, since the generated code has defaults for all the values (they are the same as the ones displayed when running a Mapping from the Deployment Manager).
