SQL 2005 linked server to SQL 2000, need to run instcat.sql

Hi,
Regarding this issue, I have replied you under your other thread at public.sqlserver.odbc community.
Please post back under that thread for further communications.

For your reading convenience, I would like to include my response below:
===========================================================
(It seems that you could not see my email response, so I directly post the response here.)

From your description, I understand that you need to update the catalog on your 32-bit SQL Server 2000
box and you need to run distributed queries from your 64-bit SQL Server 2005 to the SQL Server 2000
instance. According to the KB 906954, you need to run instcat.sql to avoid the known error. Your question
is:
How will the method affect your SQL Server 2000 production database?

By now, there is no known issue for carrying out this method. However since the instcat.sql will update
some system stored procedures, it may impact some of your running functions that are using these SPs
(SQL Server replication will use some of the system procedures). Generally every time when you do such
operations, we recommend that you perform a test before you put it into production environment.
However since this issue was because that the system stored procedures were not updated
automatically during your SQL Server 2000 SP3 or SP4 installation in your production environment, it may
be hard to reproduce this issue in your test environment, so my suggestion here is that for not causing
other problems, it is better to stop your replication and other database operations when you take this
action. This process should finish within a short time and then your replication and other applications
that may use the system stored procedures can be resumed. If you really cannot arrange a break time for
doing this, please arrange a not busy time for your database server to run the script.
================================================================

If you have any other questions or concerns, please feel free to let me know.


Best regards,
Charles Wang
