T-SQL script to automate the process of transferring SQL server 2005 login from SQL server 2005 mirror primary site to DR site

Dear all,

I have a script to automate the process of transferring SQL server 2005 login from SQL server 2005 mirror primary site to DR site, see attached.

but it doesn't take care the transfer or change of login status ( disabled/deleted).

see the statement here:

	If Not Exists (Select 1 From sys.server_principals
				Where name = @LoginName)

Open in new window


so it only copy new login but not any altered login and deleted login,

any way to improve it ?

>>so it only copy new login but not any altered login and deleted login,

I'm not sure if I follow you exactly, but if you've deleted a login, there isn't one to copy.  Are you saying that if you delete a login, you want that action to also occur on the mirror server?

If that is what you mean, you probably need to revise your script to first compare the logins between the Principal and the Mirror.  Then, of course, if there is no match at the principal, you can assume the login may be removed from the mirror.    

A slightly more complex, but potentially safer, method would be a database trigger that fires when the DROP LOGIN is run on the Primary.  These logins could be written to a table within a DBA administrative-type database, which could then be referenced to perform the same action in the Mirror.

I say 'safer' because this allows you to review the login actions -- delete or alter -- before pushing the changes to the Mirror.  


Same principal could be used for the 'altered' logins.

yes sure ! that's why I am going to inprove this script further, that scritp can handle new login and disabled login but not deleted login

Already has a plan but for that script, has to run on DR server, I can't trigger it from primary server. can I make the trigger to execute the Script/sp  located on DR server ?

"These logins could be written to a table within a DBA administrative-type database, which could then be referenced to perform the same action in the Mirror.

The while loop in the script already doing this!  but temp table.

I don't understnad why and what it means, please say it again.

if  I create a SP by that script on the DR mirror server, can I call that remote SP from mirror primary server like that by DDL trigger so that whenever a new login added/altered, the remote SP fire out and get new login from primary server?

Create Trigger CopyLoginsToDestination
On All Server
After Create_Login, Alter_Login
As
exec <mirror DR partner serer>.master.dbo.dba_CopyLogins 

Open in new window


will it works in this way ?
