Hey guys,

I have tried to connect to a Oracle 8 server using a 10 g Client and receive this error

I have put up this issue on other forums and they have informed me tht it is not compatible ......

However it is compatible with a 9 server .....

If it aint compatible then what the fix if I have a 8 server and i need to migrate an application which currently uses 8 .... to the same application which would in its new release need a 10 Server ?


***********ERROR***********

ORA-12705: invalid or unknown NLS parameter value specified

***********ERROR***********


Has anyone received this error message before ?

Please inform me of any solutions

Sherwin.

If you try to use 8 and 8i software against 9i and 10g
possibly you will run into a problem.
The problem is that in 9i and 10g are introduced new
character sets (AL32UTF8 that stands for 4-bytes Unicode).
these character sets are not known in the old good Oracle 8
and Oracle 8i world .....

You get this because the Oracle client cannot interpret the NLS information received from the Server (because of version missmatches between client and server)

Intsall an Oracle8i client and Oracle10g client in different homes, and use the one appropriate to the database version you are connecting to.

Alternatively, as long as you are not using new datatype is 10g, you could possible use a Oracle9i client to connect to both Oracle8i and Oracle10g :)

What is the NLS_LANG entry (in the Registry or environment variables) of the computer your Client is running? AL32UTF8 is not good one....
