Reverse Database Problem - Oracle 9i

Hi.

I am trying to get the ERD for my Oracle 9.0.1.2.0 schema. I am using the latest VP Suite 1.1, DB Visual Arch 1.0. The problem I have is that “reverse” program imports non-existing columns. Check the screenshot.

Tried different jdbc drivers from oracle, 9i, 8i. Also tried different oracle instances on 9i and 10g. Always the same.

Do you have an idea why this is happening. The tool seems to be nice but this problem is a definite showstopper.

Thanks.

Dear Dan,

We are sorry for any inconvenience this problem caused you. Would you please send me the vp.log file? The log file can obtained by open the about dialog and press the Export log file button. Or if possible, can you also send me a sample schema which will cause this problem? You can upload the files to this forum or directly sent to my email address:
rain@visual-paradigm.com.
Thanks in advance!

Hi Rain.

I cannot upload the schema to you as it is confidential. But I think I found out what the problem is.

Try creating two users in the same oracle instance, who will obviously have two separate schemas. Try creating several tables with the same names in both schemas. And then try importing one of the schemas through the reverse database process. You should see the extra columns. I assume that the number of extra columns is double the real number.

Of course those two users should have privileges to access each other’s schema objects. The problem is reproducable like this.

Thanks for the help.

Oh, sorry, about the vp.log file. There is nothing reported in it, aside from the startup message. One line:
