ORA-12705: invalid or unknown NLS parameter valuespecified

Hi

We just upgraded Oracle upgrade in BW landscpae without any problem. Now I'm in the process to upgrade Oracle from 92050 to 10.2.x. for XI landscpae. Here XI is running on HP-Unix and brtools and sapkernel version is 6.40. and Oracle client software version is 92050.

As per databse upgrade guide of Oracle 10g, I upgraded the dboraslib, brtools and SAP kernel (disp+work). After that i upgraded the oracle client software to 92080.

I restarted the server. Now when i executung jobs in DB13 or when i'm creating a new tablespace, it failed with "ORA-12705: invalid or unknown NLS parameter valuespecified".

I perfored the same steps in BW upgrade and this problem has not occured. I checked the env variable of orasid and sidadm. It seem to be fine.

Any reason for this problem?

Regards

Amar
