DR Scenario

For High Protection mode (2servers, no witness, FULL safety), in the event of a catastrophic failure of the principal, can a remote (but well connected) mirror be forced to assume the principal role? The MS manual "Database Mirroring in SQL Server 2005" on p2 says the failover type for HP mode is manual only (as opposed to forced). Elsewhere it seems to seems suggest otherwise but there is no clear and unambiguous discussion describing the exact procedure.

Can anyone clarify this matter? Thanks,

Bud

Since posting this question I have found in the May 2007 SQL 2005 Books On Line a clear statement that the mirror server in the above scenario can be forced to the principal mode.

Bud,

In high protection mode the failover is Manual. As no witness server is available automatic failover is ruled out. So the manual failover is done as follows,

1.either clicking the Failover button in the Database Properties/Mirroring dialog in SSMS or

2.ALTER DATABASE DBNAME SET PARTNER FAILOVER

once it is done the mirror server will become the principal server.

refer, http://sql-articles.com/articles/dbmrr.htm

Bud

Just to add. Your statement stated that you can FORCE a failover. In High Protection you dont need to force a failover because the data is in sync. You only force a failover in High Performance mode using the

ALTER DATABASE <database> SET PARTNER FORCE_SERVICE_ALLOW_DATA_LOSS

because the data may not be in sync and you are accepting the loss.

DR - Restore Master

I am doing a DR test and I am running the command sqlservr.exe -c -m to put
the server in single user mode before I restore the Master database. My ques
tion - How long does this command normally run?
Thanks,
JessThe command prompt window will sit there, it is running the sql server =
process, so it stays until you shut it down (either by CTRL + C, or a =
shutdown command from osql or Query analyser)

window it will keep running as long as SQL Server is running in single user
mode.

DR - Master db restore

I am doing a DR test and running the command sqlservr.exe -c -m to get the s
erver in single user mode. How long does this command normally run?
Thanks,
JessI am assuming you are running this in a command window. If so, it will run
until you hit Ctrl-C and answer yes to the prompt. When you start SQL
server this way it is starting as an application.

As soon you run sqlservr.exe -c -m from command prompt the sql server starts
in Single user mode. One user can login to SQL server and perform all the
activities. After that you can close the sqlservr.exe which is running from
command prompt using CNTL and C key.
Alternately,
You can start the SQL server in Single user mode using
COntrol panel -- Admin tools -- Services , Select SQL server Services and in
parameters you can put -m and click the start button. This will also start
the SQL server in single user mode. Once the actitivty is completed you can
just restart the service to make it Multiuser.
Thanks

double click SQL Server Express and install with sa password

Hi!

Is it possible to double click the sql server express installer, it will install sql server 2005 in silent mode, set sa password..

Just want alternative of command installation on double click

setup.exe /qb INSTANCENAME=<InstanceName> SAPWD=<StrongPassword>

is it possible

thanks in advance

No, double-clicking the installer will always launch in UI mode, not quite mode.

Mike

Thanks for your answer

Is there any way, the installer automatically checks the settings file while installation. On double click it reads instructions from the ini file and continue installation...

Perhaps these will help.

dopping the database which is in emergency mode

I have a Database in suspect state and i have changed it to emergency mode and copied all the data and i am trying to delete it or renaming it so that i can recreate the db with the old name as my aplication will be looking for that database name.
When i tried to drop the database it says its in use and cannot be dropped.
And when I tried to rename it It gives me the follwoing message.

To change the NAME, the database must be in state in which a checkpoint can be executed.

Please advise me .

Thanks.Enterprise Manager likely still has a connection to the suspect database. Close EM, and drop the database via Query Analyzer (while logged into the master DB, of course). Just another reason why Enterprise Manager is evil.|||Did you identify the reason for Suspect mode?|||My data files and log files were corrupted and i dont have a backup for the DB. So I have placed the db in emergency mode and copied all the tables and data using query analyzer. But while copying the table and data i could not get all the constraints on the tables.

I have copied the tables and data using the following sql command

SELECT * INTO aaa from aaa.

How can i bring the db into active which is now in emergency mode.

Thanks.
