Linked server queries getting EXCEPTION_ACCESS_VIOLATION message

Help? I am an Oracle DBA struggling to support SQL Server.
Using EM I added another SQL Server database to Linked Servers with Windows
authentication. In Query Analyzer I attempt a simple SQL query and receive...
Process 54 generated fatal exception c00000005 EXCEPTION_ACCESS_VIOLATION.
I read thru BOL and Robert Vieira's book to setup the distributed query, and
I believe I am doing everything correctly. Scanning Google and MSKB, it
seems I hit a bug with SQL Server, but this is so simple I have a hard time
believing that.
Is my only recourse to call support? Is there anything I can check?
Chris
It depends...the problem can be caused by a ton of
different things which is why it's often recommended to open
up a case with support.
What version of SQL Server? Are you on the latest service
packs?
Does this occur with any server and any database or just one
specific server and one database?
Make sure the servers, databases involved are running
correctly - check both servers server names with
@.@.Servername. Make sure the database you are accessing does
not have any consistency problems - run a dbcc on the
database you are accessing.
You may also want to check your mdac installation on the
servers. You can use the mdac component checker to do this.

We are currently running SQL Server 2000 with SP3a in Windows 2000 w SP4.
This occurs when I try to query tables on another instance on the same server.
We have a maintenance plan that performs the dbcc checks on a regular basis.
So no problem there.
Basically, I need to be able to compare the tables in the current (dev or
test) databases with a "baseline" database. So I decided to try the
distributed query from the baseline database against the dev database and it
works. But it fails the other way Or when I try to compare dev database
against test database it fails. So for now I'm ok. Later, I will
troubleshoot why I cant go from dev or test database to the baseline database.
Thanks Sue!!

Linked Server problems with Visual Foxpro

My company is using SQL 2000 and a Visual Foxpro
database. In order to perform joint queries against the
two data sources, we set up a linked server definition to
the VFP data source. Everything was working perfectly
until the other day, when I noticed that the server had
not been updated in quite some time. I installed SQL 2000
SP3a, which worked just fine. However, after that, when I
submit a query that uses the VFP linked server, it does
not work like it did. If the VFP part of the query is
going against a local view defined in the VFP database,
sometimes it works, sometimes it doesn't. There are no
error messages, nothing to indicate there is a problem.
It just doesn't return any rows. This is true if I do the
query through EM, Query Analyzer, or via ODBC connection
to the server. This is a critical situation. I even went
so far as to remove SQL 2000 and re-install and NOT
upgrade to SP3a. No change. Any assitance in this area
would be greatly appreciated. Thank youJohn,
It's never a good idea to just apply service packs without testing first.
Have a look here and see if this addresses your issue:

Linked Server Problems from SQL2005

When I run linked server queries from SQL2005 it fails.
Query Example :
SELECT * FROM [servername].master.dbo.sysobjects
Error:
OLE DB provider "SQLNCLI" for linked server " servername" returned
message "Communication link failure".
Msg 10054, Level 16, State 1, Line 0
TCP Provider: An existing connection was forcibly closed by the remote
host.
Msg 18452, Level 14, State 1, Line 0
Login failed for user '(null)'. Reason: Not associated with a trusted
SQL Server connection.
Notes:
The linked server is configured to use the current logins security
context. It does not matter whether I connect to SQL2000 or SQL2005.
I have a case with MS (6 hours on the phone yesterday), but no help
yet. All spn settings are as recommended by Microsoft. The MS engineer
states that SQL is not passing the login as indicated in a capture file
from netcap.
Any help is appreciated.
TerryHi
Is the remote server SQL2005? Have you tried using a SQL Server login? Can
you use openquery to return the result?

You are connecting to ServerA using Windows Authentication, not a SQL
login. The linked server connection is attempting to pass your SQL
login over to ServerB. You'll have to login to ServerA using a true SQL
login, or setup an explicit user mapping in the linked server definition.

I assume that you are using the latest service packs on both instances?
Previously this error has been the result of a virus checker or firewall
blocking communications or possibly a faulty network. Do you get any command
s
running on the remote system?
Windows authentication should not require the user to map a linked server
login, but you can run it with the remote server name parameter only to make
sure these are mapped.
You may want to try and check what protocols you are using and try a
different one!

You may want to make sure that this still occurs on the latest hotfixes for
each version. If that fails you may want to raise an incident with PSS for
this.

linked server problem slow queries

We're using SS2000 SP4 on both servers. We've been running the following
query for 6 months or so. I'm not sure exactly how long it used to take
because the whole job has about 10 queries. But the whole job used to take
about 2 hours. Now this query alone can take 3 hours.
use branch_master
update t set t.branch = z.branch_new,
t.branch_old=z.branch_old,
t.reassign_date = getdate()
from server2.promo2004.dbo.tblmail_resp t, branch_master..tblZipReassign_New z
where z.ziprequestid = 58
and t.prop_zip = z.zip
and t.branch= z.branch_old
and z.process='Y'
and z.update_type = 'A'
However, if we change the query and put it on the remote server it runs in
under t seconds. Here is the query we use on the remote server.
use promo2004 --on maximus2
update t set t.branch = z.branch_new,
t.branch_old=z.branch_old,
t.reassign_date = getdate()
from tblmail_resp t, server1.branch_master.dbo.tblZipReassign_New z
where z.ziprequestid = 58
and t.prop_zip = z.zip
and t.branch= z.branch_old
and z.process='Y'
and z.update_type = 'A'
I don't know if it makes any difference but the tblmail_resp table on
server2 has about 8 million rows and the tblzipreassign_new table on server1
has about 2500 rows.
We have the same problem with a couple of other jobs have queries that go
from server1 to server2 and they have slowed down a lot of in some cases run
for over 8 hours before we stop them.
Any ideas?

Linked Server Problem from SQL 2005 to SQL 2000 Database

I have been unable to get my linked server to work when running queries against it in SQL Server 2005.

Example SQL Statement on my SQL 2005 server that I'm trying to run:

select top 100 * from [linkedservername].databsename.dbo.tablename

Error Message:

Msg 7416, Level 16, State 1, Line 1

Access to the remote server is denied because no login-mapping exists.

Print screen of the security properties of my SQL 2005 Linked Server:

http://www.webfound.net/linkedserver.jpg

The user sqladmin definitely has the right permissions to the right databases on the target linked server.

On your screenshot, your login is dschinkel, it doesn't have a mapping. If you want all of your accounts to automatically use the apexfm\sqladmin account, you should select the radio button that says "Be made using this security context:" and fill in the login information there.

Be advised that if SQLAdmin has full administrative privileges on the remote server than ANY user with access privileges to the local server will have full admin privileges to the remote server. A very scary proposition indeed.

Linked Server and Non-sysadmin User

Hi,

Can a user not belonging to sysadmin fixed role run queries against the linked server (Excel Linked Server)? User has permission to the folder/file (Excel File).

If not possible, can this be achived using Proxy account?

Thanks

Linked Server ?

Hi,
When working queries with link server is it possible to
invoke user defined functions from linked server?
Thanks,
SachiYes, you can invoke a user defined function from linked
server. Though, I am not sure if Table-valued Functions
can be invoked from linked server.

Linked Server

I have a linked as400 and have successfully executed queries against it.

e.g select HDRID,HDRDSC from openquery(SERVER,'select hdrid,hdrdesc from MMTTHOF.table')

I have a problem however when I try to compare a column in my local database with one on the linked server.

The error received is:
"Cannot resolve collation conflict for equal to operation."

I have played around with the Remote Collation and Collation Name settings in SQL Server but to no avail. I then used DTS to bring the table from the AS400 in to the local database and tried running a query against it linking a Char(3) field to its counterpart in the other table. The same error occured. I solved this by changing the collation on the fields in both tables to Latin_General_CI_AS (Although I understood the default dB collation to be SQL_LAtin_General_CP1_CI_AS, so I thought this would have worked).

Anyhow I'm still unable to run the query against the original AS400 table.

Any thoughts would be much appreciated guy's n gals

JBrute force is sometimes appropriate. When using a linked server, it is sometimes simplest to pick an arbitrary collation that works well, the force both of the columns to use that collation!
