Hebrew Characters...Chars display as junk after import from 8i to 10g
Gurus,
I have a problem with a customer upgrade...
Background of the issue... the customer is an Agile PLM customer of version 8.5 (Agile PLM version 8.5). The database was hosted on oracle 8i. He is intending to upgrade from Agile 8.5 to Agile 9.2.2.4. During this process he has upgraded he db from Agile 8.5 to Agile 9.2.2.4, and has also shifted the DB platform from 8i to 10g.
Problem: There were hebrew characters entered in Varchar2 columns (Oracle 8i), which after upgrade are not displaying correctly. Newly entered hebrew characters after upgrade display correctly in UI...
Customer DB Parameters : The nls parameters on the source db before upgrade(8i) are American_America.WE8ISO8859P1, and the destination db parameters are American_America.UTF8.
What i have done to deal with the issue: i have tried exporting the db using UTF8 and importing the db to 10g on UTF8, but still the characters show as garble characters..., have tried various options of exporting/importing using the combinations of WE8ISO8859P1 char set as well as IW8ISO8859P8 charsets, as i have learnt during my research abt the charsets that Hebrew Characters are supported in IW8ISO8859P8 charset and not WE8ISO8859P1. My suspicion here is that the problem is with the export and import from 8i to 10g, and the Char conversion which is happening during this process..(this is my guess and i might be wrong tooo...)
Currently this is a hot issue with the customer, and needs an immediate fix (to display the Hebrew characters properly after upgrade)
I am a layman on the NLS Settings and couldnt figure out what else to do....I would request all the Gurus out there to help us figure out the problem and try resolve it...
Thanks for your Help in Advance
Regards,
Raja.
