Hello,
Am I reading it wrong or can I have a developer edition as a partner?
http://www.microsoft.com/technet/prodtechnol/sql/2005/dbmirror.mspx Please take a look at the Database Mirroring and SQL Server 2005 Editions section.
Anyone knows?
Thank you.
Hi,
View 6 Replies View RelatedHi, i am working with SMO object,
At the time of accessing remote(LAN) database server I encountered the
following message: "MirroringPartnerInstance" : Undefined error.
I m not able to figure out whats the exact problem is..
i had gone through the following link too but doesn't make any sense to me :
msdn2.microsoft.com/en-us/library/microsoft.sqlserver.management.smo.database.mirroringpartnerinstance.aspx
All i understand is i need to set some property of mirroring partner.
Does any on have any idea how to resolve this problem
Thanking you all in advance

Hi,
I was hoping to learn from real world experience regarding the hardware requirements for SQL 2005. For both the 32 and 64 bit OS the minimumn recommendaiton is single processor, 1GB or more, 512 MB RAM.
http://www.microsoft.com/sql/editions/enterprise/sysreqs.mspx
This seems very thin and I was wondering if anyone had recommendations for hardware configs for a mirrored db cluster? I'm filling in as a DBA and apologize for the ignorance.

I've read that when this run's, it removes all db mirroring information on that db. What exactly does it remove?
Here's my senario:
We are using SQL 2005€™s db mirroring process. We are using the certificate method of authentication between the principle and the mirror db€™s.
My question is that when the ALTER DATABASE dbname SET PARTNER OFF is run, does it remove these certificate settings as well? In other words when I want to enable the db mirroring, will I need to recreate these certificates or just recreate the endpoints to use these certificates?
Running this query in DR server to start SQL mirroring but encountered an error below.
Query:
use master
go
alter database test set partner= N'TCP://HOSTNAME.DOMAIN.GROUP.INTRANET:5023'
go
Error:
Msg 1452, Level 16, State 6, Line 2
The partner server instance name must be distinct from the server instance that manages the database. The ALTER DATABASE SET PARTNER command failed.
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?
Anyone know where to find some hardware requirements based on database size? Thanks!

Using SQL Server 2008, we would like propose mirroring between two servers of a critical database. Since we initiate, may require to clarify on its purpose and also required changes from application end.Any changes required from OS Level? (I believe both servers IP or Host name should be added in host entries. Mirroring ports should be allowed/open including Principal and mirror server IP Addresses): Windows Team.Any changes required from Application? (Instance name, authentication: user name and its password should be added in web config files): Application Team.Any changes required from Network Team?Also for mirroring both the principal and mirror servers should be with same version, does it only mean SQL Server 2008 versions are enough or does it also mean to say build numbers 10.00.4000 should also be same.URL....
View 5 Replies View RelatedI have just finished configuring my first test mirrored environment (High safety mode). I setup the database engine service accounts on each of the servers with domainuser. I inherited a production mirrored environment set up by someone else. On the production servers the database engine service account is NT Authorityuser a local account. I am trying to practice installing Windows updates within a mirrored environment and I not sure how to proceed when the service account is NT Authority user account. should I change the service account to a domainuser?

ALTER DATABASE foo set PARTNER = 'TCP://10.3.3.1:1234'

Hi!
I have the following error during setting partner on mirror server
Msg 1431, Level 16, State 4, Line 1
Neither the partner nor the witness server instance for database "masterserver" is available. Reissue the command when at least one of the instances becomes available.
The partner is available through telnet. I've also checked ports vai netstat and have no found errors.
There are two noteworthy erros in the error log at mirror server
Error: 9642, Severity: 16, State: 3.
and
An error occurred in a Service Broker/Database Mirroring transport connection endpoint, Error: 8474, State: 11. (Near endpoint role: Target, far endpoint address: '')
Security settings it seems are set accurately.
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.
We have a database,which has been mirrored.Also,We have an application which uses OpenRowSet to connect to this database.
Is it possible to set "Failover partner" in OpenRowSet connection string,so when we failover from Prinicple server to the mirrored database,The application still will continue to work?
Example:
select
*
from openrowset(
'SQLOLEDB',
'Data Source=Server1;Failover Partner=Server2;trusted_connection=yes;','select top 10 from Database1.dbo.Table1'
) temp
I need to connect to mirrored SQL servers (Developer Edition) using OLE DB, I tried both OLE DB and ODBC, but it doesn't work
I used connection ODBC string:
Driver={SQL Native Client};Server=10.0.1.161;Failover Partner=10.0.1.162;Uid=test;Pwd=test;Database=TestDB
if server 161 is principal and server 162 mirror, it connects ok, but
when I exchange server roles, connect fails (the error message is:
Cannot open database "TestDB" requested by the login. The login failed.
in LOGIN)
the connect string using OLE DB is:
Provider=SQLOLEDB.1;Persist Security Info=False;User
ID=test;Password=test;Failover Partner=10.0.1.162;Initial
Catalog=TestDB;Data Source=10.0.1.161;Use Procedure for Prepare=1;Auto
Translate=True;Packet Size=4096;Use Encryption for Data=False;Tag with
column collation when possible=False
error message is the same
when I try to connect using VS 2005 using connection string
Database=TestDB;User Id=test;Password=test;Server=10.0.1.161;Failover
Partner=10.0.1.162, it works OK
i have installed SQL server 2005 (on local - client machine) with SQL Native Client and also
SQL Server service pack 1
Is there any way how to connect from OLE DB?
Thanks
We have a pair of SQL 2005 SP2 with Rollups clusters. We have a series of DB's that we are migrating from an existing SQL 2000 cluster. I have scripted the process, however on one of the test DB's, it goes to "In Recovery" as soon as I issue the Set Partner statement. There are other DB's on the same cluster mirrored with no problems. As we have a bunch of DB's to migrate, I want to figure out what would cause it to start a recovery. After the initial restores are done, it is in "Restoring" for a status so everything works up to that point.
Thanks

i tried to set up mirroring having only principal and mirror. mirroring endpoints were easily created for both servers. when i try to add the partner name it responds with
Msg 1418, Level 16, State 1, Line 1The server network address "TCP://machine1.domain.com:5022" can not be reached or does not exist. Check the network address name and that the ports for the local and remote endpoints are operational.
On the log of machine1 i see,
Database Mirroring login attempt by user 'NT AUTHORITYANONYMOUS LOGON.' failed with error: 'Connection handshake failed. The login 'NT AUTHORITYANONYMOUS LOGON' does not have CONNECT permission on the endpoint. State 84.'.
i have similar problems as in
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1020144&SiteID=1
i am a sysadmin on both SQL Servers and have connect permission on both end points.
Both the endpoints are in started state and listening to all IP's
Both services are as 'Local System'
As per what was mentioned in the above post to add a 'domain/machine$' user did not help.
Tried using setspn.exe to add a new SPN MSSQLsvc/<HOST>:<MIRRORINGPORT> did not work. an ERROR comes 'not enough privileges'
setup shows the following SPN only on both
HOST/Machine name
HOST/Machine name.Domin.com
MSSQLSvc/Machine name.Domin.com:1433
SMTPSVC/Machine name
SMTPSVC/machine name.Domain.com
and on second machine
HOST/Machine name
HOST/Machine name.Domin.com
MSSQLSvc/Machine name.Domin.com:1433
any Clues?
Hi
Sincere Apologies for the cross posting. Did not realize that there is a specific DB Mirroring group and so posted initially in the High Availability group. Here is the original post
Hi
I am trying to test DB Mirroring connectivity and running into a road block. using SQLOLDB in my connection string the failover partner keyword seems to be not recognised when the failover occurs and the connectivity fails. The same however works with the SQL Native client driver.
Can any expert please let me know what I am doing wrong and what is the right connection string for the OLEDB one?. I also tried using different flavors of FailoverPartner (like Failover Partner, FailoverPartner etc) to make it work with OLEDB but still could not connect with SQLOLEDB provider.
SQLNCLI works with no issues at all.
Connection string code samples included.
--Code that does not work
Code Snippetconnstring = "Provider=SQLOLEDB;network=dbmssocn;Data Source=Server1SQLInst1;FailoverPartner=Server2SQLInst2;Initial catalog=mydb;INTEGRATED SECURITY=SSPI;"
Code Snippetconnstring = "Provider=SQLNCLI;network=dbmssocn;Data Source=Server1SQLInst1;FailoverPartner=Server2SQLInst2;Initial catalog=mydb;INTEGRATED SECURITY=SSPI;"
Any help is appreciated.
Thanks

I am getting this error while trying to setup mirroring.
"Neither the partner nor the witness server instance for database "shop" is available. Reissue the command when at least one of the instances becomes available. (Microsoft SQL Server, Error: 1431)"
I am just using principal and mirror server, there is no witness server. I have tried fully qualified name and ip for the servers also. I can connect from the principal server to the mirror server using the management studio and it also creates endpoints on prinicipal and witness. But then gives me an error that it cannot find the instance of the mirror server and if I try again it gives the error above. I can also telnet to port 5022.
I have used -T1400 as the startup parameter.
I did the backup and recovery based on this link http://msdn2.microsoft.com/en-us/library/ms189053.aspx and the mirror server is in recovery mode now.
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.
Hi All,
Couple of questions about database mirroing.
1. Once the mirroring is setup is it possible to switch between high-protection and high-performance modes? If it is will I have to stop the mirroring, switch the modes and then restart it again?
2. Let's say the principal server went down and I manually failed over to the mirror server. Mirror server runs as a new principal server for a couple of days and then I bring the original principal server back up. What needs to be done in order to bring transactions on the principal server up to date?
Thanks.
for a database mirroring , which stretergy is good.
Creating with witness server or without it.?
I am firsttime doing this , so i am posting it to the forum..
and also if we are creating the database mirroring with witness server for automatic failover , will the witness server need the same amount of harddisk space like the pricipal or mirror server.??
thanks
we want to migrate our production server , without taking the database down.so what we did was , we mirrored the databases from production to one of our development servers and we took the prodcution server for uprgrade.
so today we are moving back (mirroring) all the databases from that development server to our new production server.
my question is , when i move
productionserver_old(principal server) - having the script for principal server
development server(mirror server---->principalserver)) - having the script for mirror server , which is now acting as principal server
new production server(mirror server) - having the script for mirror server. will become principal server , once i moved all the databases
now while mirroring between the developement server and the new production server, i have to run the scripts for the mirror server only.
so both the servers are havign the mirror script now...
is that a problem, or any other way i can handle this....
Hi All,
Does anybody know any good Tutorials for Database Mirroring (Automatic Failover) or Manual Sync with Mirror Server. I tried some sites online, but doesn't have detailed steps..
pls.help as i need to sync data with One of my Mirror using Sql Server 2005.
thanks
Hi,
I have some questions about database mirroring. we have almost 40 databases in one server. Can I set up the database mirroring for all the databases.

Can we have database mirroring for two databases. Like i have an application where in the db used are two, namely DB1 and DB2, DB1 is used in the connection string and with the help of DB1 the tables and sps of DB2 are handled.
in this case can i go ahead with database mirroring. Please comment and give the idea or link on the same.
Hi,
Is there a way to automatically mirror/backup a SQL Express database with a SQL Server 2005 licenced system?
They will be on seperate machines on the internet.
I have done manual backup and restores but would like to allow constant updates to allow both databases to be synchronized.
I read that the SQL Server 2005 version has a mirroring facility but I also read that this is not possible in the Express version.
What other (automated) options do I have?
Thanks Andrew
We were having problems setting up the mirroring, so I did it via command lines. I found out the "alter...set partnership" command works on the mirror server going to the principal, but gets a 1418 error when going from the principal to the mirror.
So if A is the principal and B is the mirror, A to B fails but B to A works.
If I reverse it so that B is the principal and A is the mirror, B to A fails and A to B works.
Any suggestions?
