we’re currently building a data warehouse using OWB (Oracle Warehouse Builder).
One of the DCS (data capturing systems) is a proprietary database (PI by Osisoft Inc); we want to integrate it using JDBC.

The repository is located on a Linux system (RHEL 5.3, Oracle 11.2.0.2, OWB 11.2.0.2),
I’m connecting from a Windows XP system (OWB 11.2.0.2).

According to the OWB documentation, I should copy the JDBC jar file to
$OWB_HOME/owb/lib/ext, add a new platform (using OMB+) and then add a new location.

I’ve tried this with SQLite, and everything seems ok, but with PI, “Test connection” in OWB doesn’t give me any feedback, and when I try to get the list of tables/views from the source system, it hangs.

Some questions regarding this:

  • is the JDBC jar file required on the “Server” side (RHEL 5.3) or “Client” side (Windows XP) (sorry if I’m using the wrong terminology, I’m still getting started with OWB)?

  • the JDBC driver requires a .dll (Win) / .so (Linux); is this possible with OWB? Or does OWB accept only “pure” JDBC drivers?

  • is there any possibility to debug the JDBC access (some kind of log file, perhaps)?

I’d be thankful for any hints on solving this.

Kind regards
Frank

    Since we couldn’t get this to work, we changed our approach:

    • OWB calls a user defined activity A1
    • A1 executes a shell script S1 on the Linux server
    • S1 calls a small java program J1 (with the classpath settings etc.)
    • J1 connects to the proprietary database using JDBC, fetches the data and writes it to a .csv file
    • OWB then loads this .csv file using an external table

    Kind regards
