Oracle Generic Connectivity

• Edit 3 text files tnsnames.ora listener.ora initpioledb.ora

• Define database link CREATE PUBLIC DATABASE LINK PI3 USING 'PIOLEDB';

• Map Oracle users to PI users CREATECREATE DATABASE LINK PI3 CONNECT TO “piadmin"

IDENTIFIED BY “password"; Repeat per user


Generic Connectivity - Demo


Be aware (1):

• Use Optional Connection Pooling In Linked Server Connection Pooling=True;

• SQL Server 2000 Cannot Write To Remote VARIANT Columns Our batch tables for example use variants use pass

through

• Current Version Can Be Used With ASP.NET Aspcompat=true

• VS.NET Database Designer Wizard Puts Brackets Microsoft Knowledge Base Article - 325790


Be aware (2):

• Older Oracle ODBC drivers cannot access remote databases Use Oracle ODBC driver 9.0.1.5.0 and above

• Oracle Cannot Set OLE DB Query Timeout Use global Command Timeout Property (in UDL file)

• Oracle Heterogenious Queries Switch Off Two-Phase Commit dbms_hs.create_class_init ('xxx', '2PC', 'SS', 'F');

• Tag Search Queries With Escape Character Other Than ‘\‘ Are Local „... WHERE tag like ‘tag\_1*‘ ESCAPE ‘\‘ ...“


Future

• OLE DB Has Not Reached Its Peak Continued tests for integration scenarios, e.g. OLAP

• Bug Fix Version - Q2/2003 Module DB XML Import/Export Utility (ADO.NET Example)

• Next Major Version - Beta Q4/2003 Move to „free threading“

Support for .NET Web Service Support for Application Framework New SQL Engine

Prepare ground for .NET Managed Provider PI ODBC?
