Kevin,

This is a bug in sqlplus. You are using two different releases Oracle, and when you are using the 8i version of sqlplus and trying to describe a table on a lower version of Oracle through a dblink, you will get this error.

The work around is: Don't do that. Seriously. It's not fixed, nor will it
be fixed. You can find details on MetaLink.

        Subject:        RE: DB Link Error - More Info

Sorry for the lack of info. Her it all is:

I have tns entries on both database machines that point to each other.
I have global_names set to false on both machines.
I have the same ID defined with the same password on both machines.
We do not use Oracle Names.

On machine A:
I created a link :
create database link b using 'b.world';

On machine B:
I created a link :
create database link a using 'a.world';

Here are the results:

I can select data back and fourth between both machines wit no errors.
When I try to describe a table accross the link I get the ORA-0219 error.
When I try to use the plsql copy command (ultimately what I want to do) , on machine B, I get an error stating that I am trying to Fetch out of sequence. On machine A I get an unknow error that can not be interpreted .... a long string of numbers as the error number.

So, thats it. Currently I am resorting to small selects accross the working part of the links. But, eventually I need to get to the copy commands because they have the commits in them.

Any help is greatly appreciated.

Kevin

are you using global_names = true? do the link names match the global names?
is there a local tns entry on the machine with database A that points to database B? we had a problem like then that was traced to our using Oracle Names without local tns files.

Does anyone know the most common reasons why a DB LINK would give me the following error :

ORA-02019: connection description for remote database not found

Both databases exist .... And even though I get this error going from Database A to Database B, the link I have between Database B and Database A works fine.
