I'm devlving into 2005 and specifically mirroring.Having read the following article (http://www.microsoft.com/technet/pr...5/dbmirror.mspx ),is mirroring a sensible option as it indicates that it should not beused in a production environment, yet the SQL2005 seminars I've been toindicate that this is a worthy option.Do we also need a witness server, or can this be done (sensibly) withtwo SQL2005 servers ?Currently we have 2xSQL2000 (clustered) servers and a SAN for the data.If we go down the route of mirroring, it looks like we can get rid ofthe SAN and Cluster and use the mirroring instead.Any advice on the pro's / cons would be appreciated.ThanksRyan

View 2 Replies View RelatedHello, My question is simply: according to BOL, a DB snapshot taken from a Mirror is read-only. Say I wanted a temporary (disposable) read-write DB created from the snapshot. Is there a way to generate a writable temp DB (that's not tempdb) from the snapshot? Thanks,AK

I get a general question about the feacture "Database Mirroring". Is it support by SQL Server Standard. Edition without SP1?? Of i still need to upgrade the server from SQL Server 2005 to SQL Server 2005 with SP1?
Another question: are there any problem if the one machine(server) has installed SQL server 2005 Standard edition and the other with "Developer Editon".
I hope some one can answer my question. Thanks anyway!

Hi all,
i have a small problem to connect SQL Native ODBC Client to a mirrored Database.
The connection goes without any problem when I connect to a primary Database, but when i give this connect string to an
ODBC Client ""Server=Partner_A; Failover Partner=Partner_B; Database=XXX; Network=dbmssocn"", then i get an connect fail.
There are no firewalls and other things on the network.
I am also able to connect to a mirror database during failover, but I'm not able to set both servers on the ODBC Connection.
Kind Regards,

I am trying to enable database mirroring for 100 database.
It goes error free till 59 databases (some times 60 databases) with the
status (principal, synchronized) on principal. on the 60th or 61st database
it gave the status (principal, disconnected). Also mirror starts acting
abnormal. connection to mirror starts to give connection timeout and it is
not enabling database mirroring on any more databases. I have SQL SERVER
2005 Enterprise with SP1 on the servers. witness is not included yet.
this are my test servers... i have more than 500 databases on my production
servers.
principal and mirror both are using port 5022 for ENDPOINT communication.
Dear All,
I have a download "SQL Server 2005 Evalution Copy". I installed it to 3 machine, 1 - XP Professional (Witness) and 2 - Windows Server 2000 (Principle and Mirror) . And I want to try Database mirroring.
However, after restore the Log into mirror server I try to execute the following statement in Principle Server:
ALTER DATABASE TestDB
SET PARTNER=N'TCP://[10.0.200.2]:5022'
GO
The above 10.0.200.2 is the mirror server IP address.
it show error message as:
Msg 1416, Level 16, State 31, Line 1
Database "SCMPGroup" is not configured for database mirroring.
In Miorror Server
I execute the statement :
ALTER DATABASE TestDB
SET PARTNER=N'TCP://[10.0.200.1]:5022'
The above 10.0.200.1 is the principle server IP address.
It shows sucess
ALTER DATABASE TestDB
SET WITNESS=N'TCP://[10.0.15.146]:5022'
it show error message as:
Msg 1416, Level 16, State 1, Line 1
Database "SCMPGroup" is not configured for database mirroring.
Please help me! I down't know if NT4 domain or evalution copy problem in there.

principal and mirror both are using port 5022 for ENDPOINT communication.
All of the databases are critical and all must be included in the Database Mirroring.
so, after that I tried to implement database mirroring again......
System has 3 GB of RAM, SQL SERVER (Mirror) using 85 MB of RAM but still
giving this error while trying to enable database mirroring for 37th
Database.....
"There is insufficient system Memory to run this query"
WHY?
Server A = primary SQL DBs (mirroring origination)
Server B = failover SQL DBs (mirroring destination)
For database mirroring a witness is required.
Can the witness live in another instance of SQL on server B?
Can someone at Microsoft comment on this article, specifically, how it relates to SQL Replication? Will SQL Replication fall into the category of what this article describes, or only the mirroring feature?

Hi everyone,
I have a project on my hand in which i need to implement two SQL 2005 servers
And configure it as DB mirroring.
I know that for the sake of 'fail over' I need to configure a witness
server as well.
My question is:
For the purpose of the mirror server and the principle server - what
are the software requirements (enterprise, standard?)
For the purpose of the witness server - what are the software
requirements (enterprise, standard, express?)
Should the witness server be a 'server' in terms of hardware...or is
it enough to establish a strong pc machine?
We just upgraded from SQL Server 2000 to 2005. In the past, when I ran the import/export wizard to copy multiple tables from one database to another with SQL Server 2000, I had no problem. Now when I used the import/export wizard to copy multiple tables with SQL Server 2005, I kept getting an error. For example, when copied three tables, the first table might be copied fine and I got an error with the second table and the whole thing stop. Sometimes I could copy two tables. However, when I ran the import/export wizard to copy each table one at a time, it worked.
The error that I got was "Cannot insert duplicate key in object..." I selected the options to "Delete rows in existing destination tables", and "Enable identity insert". What am I doing wrong?

Hi
I'm a newbie at SQL 2005 and I'm trying to create linked tables to our ERP system through ODBC. I can do this in MS Access or vb.net by using the ERP system's ODBC driver, but I am lost when it comes to SQL Server 2005.
Thanks for any help
I set up a new mirror server. Everything is good except that the Database Mirroring Monitor is not working for one of the databases. In the monitor the principal data is showing up as blank
If I look at dbm_monitor_data on the principal most of the data columns (e.g. Send_queue_size) are null where as they have data for the other databases.
Both servers are SQL Server 9.0.2047 Enterprise Edition.
Any idea what might be going on here?
Thanks in advance.
Hi guys,
I have read many articles on the matter and I have probably used up all my printer's ink in doing so, however, some questions still remain.
1) What happens if I have to reboot the mirror.. security update, etc.? Obviously the session is broken during reboot, but would I have to do another backup of the principal and resync everything?
2) I know it is not best practice but at this point I have no choice, however, I wanted to get your guys feedback on having two instances of SQL2005 on my development box. One for the mirroring of the production and the second for development. The two instances would live on their own drive... not partitioned and have adequate memory and space.
What would I have to look forward with this?
3) Lastly, I am still uncertain if mirroring is approved for production. Is it?
Thanks for your help.
I am working on a proof of concept to take to our Technical Board.
This POC is concearned with SQL server 2005 Mirroring for High Availability and Failover in a Highly Critical business sector.
The problem is that we use custom web pages to give the Operations Center an overview of the status of the system and that there are so many metrics available (not may are well documented). I have looked at the following
sys.database_mirroring_witnesses
is_suspended to show the state of the Sync
database_name to return the name of the mirrored database
safety_level_desc to show that the Safety level is at Full
Principal_server_name to show the name of the Principal server
Mirror_server_name to Show the Name of the Mirror Server.
I am at a loss as to what is the best approach as I do not want to display too much Information and confuse.
The Servers are locked down to remove any permissions not required so I have to create a SQL account with only acces to the required sys views. one issue is that the following SQL only works on the Principal
Code SnippetSelect * from sys.database_mirroring where mirroring_guid is not null
The Principal returns
Code Snippet
7 267CF8D3-8066-44EA-84BD-B7EA25C3F779 4 SYNCHRONIZED 2 MIRROR 20 2 FULL 1 TCP://DNGLHRSQL051.XX.XX.XXX:5022 DNGLHRSQL051 TCP://LHRSQL029.XX.XXX.XXX:5023 1 CONNECTED 40000000010300001 10 NULL UNLIMITED
where the Mirror will return nothing..
The configuration of the User is identical on both Principal and Mirror and is as follows
Master Public
MSDB Public, dbm_monitor
I have read that the User also requires "view any Database" but on the Mirror this database is not available on the Mirror as it is in Sync.
Is this an undocumented Feature?
Any help greatly appreciated
Regards
Andy
I am trying to set up a SQL mirroring senario - I have some questions
Do I need to purchase an extra SQL Server license for the SQL server instance on the Mirror? what about the Witness does that also need a separate license/
Can the witness be a virtual server on the Mirror box itself? Do I still require a license if the witness is on a virtual server?
Thanks

Hi all,
I am using SQL 2005 (Enterprise Edition, SP2) Mirroring with a Principal, Mirror and Witness set to High Safety mode and am a little confused!
As far as I understand it, during a failover, although the database content will automatically be available on the Mirror any user accounts will need to be either manually created or manually mapped to the new principal. Is this the case? If so, I can't really see the purpose of using Mirroring (in my scenario anyway).
For example - We principally use the database servers for our web applications which we connect to using ADO.NET. Each database and Web app has a different SQL user account to allow access etc. If we experience a failover this means the users will not be able to use the web app until we have manually recreated/mapped the SQL accounts for each and every database. Surely this is a massive oversight?! Or am I simply getting the wrong end of the stick.
Any help/guidance would be greatly appreciated!
Thanks,
Richard
Hi All,
Does anybody know the OS requirements for Database Mirroring? I checked BOL and Google but couldn't find any info on that.
Thanks.
Hi All,
I have read on the web that high protection mode not recommended, except in the event of replacing the existing witness server. But I can't find the reason why anywhere. Can anybody explain? Thanks.
