It’s unicode related - which version of Oracle are you using and what was used to create the database? You might have to change the connectivity settings in the BO dataAccess files.
Apologies for dredging up an old post but thought this might be of interest.
I am using Oracle XE 10g for a demo system but got the same error when creating a webi doc. (The error is in the trace files rather than on screen, on screen is the processing dpCommands error).
Oracle XE isn’t a supported platform and this fix is not recommened for any production type system so only use if necessary.
To allow this charset edit the oracle.crs file (on linux) this is under [install]/enterprise115/linux_x86/dataAccess/RDBMS/connectionServer/oracle
at the end you should see,
;
; Unicode configuration
;
UTF8=UTF8
and after this last line add
AL32UTF8=UTF8
I don’t know if this will handle non western characters but so far it seems to work for my small demo system.
I got the same problem in oracle 10g, when i wanted to refresh any report i got CS:Invalid native charset : AL32UTF8 error,
but i could solve this by ( regedit>>HKEY_LOCAL_MACHINE>>SOFTWARE>>ORACLE>>KEY>>NSLANG= AMERICAN_AMERICA.WE8MSWIN1252)
make NSLANG value = AMERICAN_AMERICA.WE8MSWIN1252 and the problem will be solved.
