How To Get Hostname

Sep 3, 2004

We are using sql server 2000

Problem:
========
A few records in a particular table are getting updated with incorrect values everyday somehow by some process. No one is manually changing these records.
Every morning I query the database and fix these records. But somehow they again get set to the incorrect values.

So I want to figure out how this is happening. I'm thinking of creating an update trigger on that table. And whenever this update trigger is fired, check the modified record's id and if it is the problematic record, then get the hostname, username, processid which is doing this update.

Can someone give me ideas on how to get the hostname, username.

Any other ideas are also appreciated

Thanks in Advance!

Hostname

Jun 18, 2008

Hi,

Question:
How do I get the hostname from the instance name please?

My present design at present is something as follows:

We have several sql server 2005 machines
i.e.
ServerSQLA, ServerSQLB, etc....

Each machine may have one or more instances,
i.e.
ServerSQLAinstace1
ServerSQLAinstace2, etc...

The server name in this case is ServerSQLA

Instance naming and node convention is different for clusters

i.e.
C_ServerSQLAinstance1
C_ServerSQLAinstance2

on the node(s):
N_ServerSQLA or N_ServerSQLB


Thanks

HostName And ReinitializeSubscription

Apr 28, 2006

Hello all,

I'm having trouble with my Merge Replication setup in regards to changing the HostName property of the SqlCeReplication object. As we all know, if you modify the HostName value, you must then call the ReinitializeSubscription(true) method before calling Synchronize(). Unfortunately, this isn't working for me. Following this sequence of steps consistently results in error messages saying that I need to either call ReinitializeSubscription, or change my HostName back to it's original value. Has anyone ever experienced this problem?

Regards,

Rob Tiffany

Restrict Login Access By Hostname/ip Possible?

Oct 2, 2007

In SQL2005, is it possible to restrict incoming sql or windows authentication logins by source hostname or IP address? Perhaps using endpoints?

We are currently using hosts file on the db server as a temporary solution, but the SA will not allow us to use this as a permanent solution.

The app team I support is asking me to build an "idiot proof" database so that an Dev or Test app server they may configure, doesn't unintentionally connect to the Production database and damage/alter data.

Don't worry, I've already asked if they can't follow some kind of M&P's to prevent this kind of silly behavior, but they insist on DBA team creating a bullet-proof database that can outsmart app developers who try to attempt something dumb like this.

Any ideas or suggestions would be greatly appreciated.

TIA,
Phil

HostName Function With Access2K Front End

In an Insert Into statement I have used the Host_Name() function toidentify which user has suppied a record to a table that holdstemporary data.I'm using an Access2K front end.Code:Alter procedure SPName@parameter1 intASSet nocount OnSet xact_abort offDeclare @myHost nvarchar(50)Set @myHost = Host_Name()Insert Into tblMyNameTEMP(UniqueID, AnyField1, AnyField2,myMachineName)SELECT tblMyName.UniqueID, AnyField1, AnyField2, @myHostFROM tblMyNameWHERE tblMyName.UniqueID = @parameter1I have two problems.In some cases (and only on one or two of maybe about 250 clientworkstations) Host_Name() returns the name of MY machine.

SqlCeReplication.HostName Size Limit Fix?

Jul 17, 2006

We are attempting to improve our merge replication process between our SQL Server 2005 server and SqlCe Mobile 3 client by switching to Data Partitions. We are using IIS as a proxy to SQL Server 2005 running on a different box using a DOMAIN account.

We've setup row filters to use HOST_NAME() and have set the option "Automatically define a partition and generate a snapshot if needed when a new Subscriber tries to synchronize" to true in the Data Partitions options under the publication's properties in SQL server management studio.

If I use a .HostName value of "1234", everything works fine. A subdirectory is created under a our publication's folder in the shared replication directory that relates to the host_name. Data is copied to the device and can be observed through query analyzer that the data is in fact filtered properly.

However, when using a .HostName based on the GetDeviceUniqueID (which results in '3D321F7212B2AD2CC824954662B9023441BB2D20'), replication works sometimes and sometimes fails with "The merge process was unable to deliver the snapshot to the Subscriber. If using Web synchronization, the merge process may have ben unable to create or write to the message file. [etc]". The final HRESULT is 80045017.

While this error indicates a permission problem, there were no permission problems when creating the "1234" partition. In researching the problem, I ran across KB905395 which states:
Limitations on the HostName property and the Subscriber-requested snapshotIf you try to initialize a SQL Server Mobile Edition subscription by using a filtered HostName property, initialization fails. This problem occurs when the value that is supplied for the HostName
property contains more than 12 characters. To work around this problem,
disable Subscriber-requested snapshot delivery at the Publisher. You
can also use a value for the HostName property that contains fewer than 12 characters.

====

This seems to be consistent with what we've observed (which actually led to the "1234" test). Does anyone know if a fix for this exists? Has anyone else run across this issue? I saw a previous post from March that did, but never got resolved. However, the KB article above was posted in March - hmmm...

This is an existing application and filtering based on the device's id is ingrained in the application. Changing it now would be large undertaking.

Sql Express As Witness Hostname Truncation

Jun 22, 2007

Not sure if this is relevant here but I thought someone might have seen this.

I am trying to set up Express edition as a mirror witness and am running into a problem.

It seems the express instance thinks its "Host Name"[1] is foo-prod-witnes rather than it's real name foo-prod-witness (notice the additional "s")

When I try to create the security endpoints everything appearsd to work as far as connecting to the express instance but i cannot start the mirror because the address listed is

TCP://foo-prod-witnes:5022 (not a valid hostname)

My enterprise editions report foo-prod-sql01.fqdn:5022

Any ideas how to fix this?

Applying HOSTNAME Filter To Subscription

Mar 20, 2008

Hello,

I am using Merge replication for synching data between SQL Server 2005 and Mobile units (SQL CE 3.5). I have created one publication and there are around 300 subscribers in the production.

If I want to use a HostName() filter so that each user gets his or her own data, do I have to set up 300 different subscriptions with different HOSTNAME values or can I use the same subscription somehow?

I would appreciate if someone can let me know whats the best way to approach this problem.

Thanks

Replication When Publisher And Subscriber Hostname Conflicts?

Sep 23, 2015

We've got x2 data centers in the US:

NYC & SAC

Sadly the hostnames for the boxes I am trying to replicate are similar:

- db1.nyc.mydomain.tld
- db1.sac.mydomain.tld

The servers can talk to each other over all necessary ports however when I generate a push subscription from the publisher, I am asked to add the SQL Server subscriber and it already shows DB1 listed since itself is DB1.nyc. How can I attach the remote subscriber when setting up the subscription from the publisher if the hostname conflicts in my unique scenario?I created a entry on the publishers host file to use db2sac for the SAC IP and entering that alias in as the remote subscriber but no dice.

Connection SQL Server 2005 With DNS Hostname Mismatch

Dec 29, 2006

When using the MS SQL 2005 JDBC driver, I now need to have the DNS nameresolution to the client correctly set up. If not I get the followingerror:SQLState: 08S01SQLError: 0Message: hostname : hostnameWhere "hostname" is the client host name. It doesn't seem to matter ifIuse an IP address or hostname in my connection URL. When searching thenet,I have seen a similar error, but not exactly the same, where themessage is"Hostname: hostname not found" (once again, here "hostname" is theclientmachine) where they suggested the issue was the DNS name conflict.I found the error goes away if the client machine's hostname match theDNSname used for the same IP addess that the DB server is using. Onework-around is to set hostname on the client to the IP address beingused.I know the right thing to do is set the hostname and the DNS namelookup thesame, but I have a customer who doesn't want to do this. They didn'thave tofor 2003, and they don't want to for 2005. Sigh. Is there a way todisablethis feature?

Cannot Access Report Manager Website By Hostname, Only By IP Address...?

Jul 26, 2007

Hello all - this has now happened to me on a few occasions (different installs, different sites, etc.), but my client PCs cannot access Report Manager by the server's hostname (even though I can ping by hostname from the client).

For instance, if I try:

http://ovenserver/reports

I get the infamous "Internet Explorer cannot display the webpage" message.

If I try:

http://10.0.0.20/reports

The Report Manager loads properly without a hitch.

I know I am missing something simple here - can anyone help?

Thanks!

DB Engine :: SSMS Connects To Different Instance With Same Hostname - If Ports Are Same

Jun 9, 2015

We have a 2 servers  with 2 default instances, 

Environment- SQL server 2012 SP2 | Windows Server 2008 R2

1server:
hostname-serverA , Instance-serverA and port-2040 Ip-192.164.1.1

2server:
hostname-serverB , Instance-serverB and port-2040 Ip-192.164.1.2

If i do a SSMS connection-the possible connections strings which can be used to connect to Instance "serverB" should be,

a.serverBserverB
b.serverB,2040
c.192.164.1.2,2040

Note: but even the connection string "serverBserverA,2040" also connects to Instance "serverB", when i try to connect from SSMS, In SSMS it shows the wrong instance name like, "serverBserverB", but it actually connects to  Instance "serverA"

i.what is the reason behind this?
ii.Is there any way to avoid this connection, by performing server property changes, if any ?

Sqlcmd With Trusted Connection And IP Address Or Fully Qualified Hostname

Nov 9, 2006

The command sqlcmd seems to fail when using trusted connection and an IP address or a fully qualified hostname. For example:

sqlcmd -E -S nnn.nnn.nnn.nnn

where nnn.nnn.nnn.nnn is the real IP address of the machine, or

sqlcmd -E -S hostname.domain.com

where hostname.domain.com is the fully qualified hostname of the machine, gives the error:

Msg 18452, Level 14, State 1, Server 380GX280B05, Line 1
Login failed for user ''. The user is not associated with a trusted SQL Server c
onnection.

On the other hand, sqlcmd -E -S 127.0.0.1 works, and so does sqlcmd -E -S hostname, or sqlcmd -E -S tcp:hostname,1433.

This is on a clean machine, with SQL Server 2005 freshly installed as Administrator with mixed authentication, and the test runned also by Administrator.

Is it normal or is it a bug?

Thanks.

Data Access :: HostName / Workstation ID Connection String In Excel

Aug 9, 2011

I currently have the following connection string set up in Excel to connect to my SQL db:
 
Provider=SQLOLEDB.1;Persist Security Info=True;User ID=XXXXXX;Initial Catalog=YYYYY;Data Source=SQL;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Workstation ID=PROJMNT1;Use Encryption for Data=False;Tag with column collation when possible=False

 What I would like to do is replace the Workstation ID (which apparently is hard coded?) so that the user's workstation name pulls (%COMPUTERNAME%) so that I can see who is connecting, using what, for how long etc etc.

Is there anyway to accomplish this?
