We have a Prinicipal, a Mirror and a Witness server. We have automatic failover configured between the Prinicipal and Mirrored server. When we stop MMSQL service on Prinicipal, not all the databases failover to the Mirrored instance.
Any suggestions would be welcomed as we have a tight deadline to get this in Production.

Any ideas on how long it should take SQL Server 6.5 running on a 8 Gig RAID 0 array to "recover" a 4 GIG database. I rebooted the machine this morning (seldom ever have any problems with it) and it seems to be taking an awfully long time (15 min so far). I'll let you know what happens in any case.

I need to recover a database, but unfortunatelly i don´t have any backup... Well, it was not my fault. Anyway, i only have the physical .DAT files of the data and log devices of the database.
Will it work if I create two devices with the same name as the old devices, create a database with the same name as the old database within these devices and then run a full script of my old database, then change the 'phy_name' on the sysdevices to point to where my old dats were, or replacing the current ones with the old ones? If not, will anything else work?
Thanks in advance.

1) How do I reinstall a fresh copy of the MSDB database (since my current
one is corrupt). Is there any script available?
2) What is the purpose of the MSDB database? Backups and jobs/ Wizards?
Thanks for your help.

I have a 3GB DB that I was running an update script on. The sript failed and ran out of transaction log space. I expanded it and stopped and restarted SQL. The user DB is now marked as recovering. How long should I wait for it to recover? I don't want to have to restore again and start all over with my script. Please help.
(By the way this is a restored DB)
Thanks.

What should I have done? Is there anything that can be done other than restoring from backup?
How does one know if the database is really recovering or is EM just joken? I can wait 2 hours
before starting the restore
I was BCPing 12 million rows into a staging table. II used the '-b' option every 20K which I thought
would do a commit and clear the log in batches. After the process EM appeared to show the transaction log
as empty. Upon inspecting the Bcp output file I discovered the message that the BCP did not complete
because syslogs was full. I could not do a truncate transaction log or a dump database. I tried to
do a truncate transaction with no_log and it appeared to just hang. I stopped the SQL Server thinking
I could dump the transaction log, but could not start the Sql Server again. I then stopped the NT Server
because 'if all else fails'. The SQL Server started but the user database if marked as recovering.

We currently have a company program in foxpro which inputs all of our information into its database. We are trying to shift from this to new updated software and a SQL database. There is a program we created which converts all the data from our old database into our new SQL database in preparation for our final move to the newer software. However, some of the tables in SQL were not taken directly from our old database but rather added in directly after our initial use of SQL, so when we ran our conversion software, a couple of specific tables were wiped because there was no equivilant within our old database. We already altered our conversion program to not touch those tables again, but is there any way to do a roll back or to find a backup of specific tables?

I'm having a problem with SQL2005 Database mirroring.
I have an ASP application that loops for a certain amount of interations and in each iteration I create a SQL Connection object and use the failover partner in the connection string. The object then writes a simple record and then the connection is closed and the process starts again.
About half way through my loop I force a failover to the server mentioned as the failover partner in the connection string. At this point my application encounters a SQL Exception error and the application fails.
I read in this article, http://msdn2.microsoft.com/en-us/library/ms366199.aspx, that this is expected and that you shoud request a new connection using the same connection string but this isn't working for me and unfortunately no examples are given anywhere.
I would appreciate any help. Thanks
Luis Bonilla
Here is a sample of my code:
Dim k As Integer = 1
Dim constring As String = "Server=SVR01.XXX.XXX.comInstanceName;Failover Partner=SVR02.XXX.XXX.comInstanceName;" _
& "Database=test;" _
& "Integrated Security=SSPI;"
Do Until k = 60
Using con As New SqlConnection(constring)
Dim cmd As New SqlCommand()
Try
con.Open() '<--------This is where the exception occurs
Catch ex As SqlException
Dim en As String = ex.ErrorCode
Dim em As String = ex.Message
Dim emm As String = ex.Number
Dim enn As Integer = ex.State
End Try
lblprimary.Text = "Current Primary Database = " & con.DataSource
cmd.Connection = con
cmd.CommandText = "INSERT INTO SystemsTest (FirstName, LastName)VALUES ('SQLWriter" & CStr(k) & "','" & con.DataSource & "')"
Try
cmd.ExecuteNonQuery()
Catch
lblresult.Text = "Results = Error with record number " & CStr(k)
End Try
con.Close()
cont:
End Using
Sleep(1000) 'For testing
k = k + 1 'For testing
Loop

Simple question, I hope. I need to add a column to a table of a database that is mirrored. How do I have to do that? Do I need to stop mirroring? Is it sufficient to simply pause mirroring? If I make the change on the principal db, what do I need to do the make the same change on the mirror?
Thanks,

A friend of mine called and said that his database was suspect and he detached it and was unable to attach it. The SQL Server Version is 2000 with the latest service packs installed. When I checked it the database (MDF) size was 1MB and the LDF size was 3.8 GB. I was not able to attach the two together and I was not able to attach the database using sp_attach_single_file_db. I did find an old backup of his database and attached that so he can work off of it but it is 1 yr old and he needs recent data. Since the MDF seemed to be blank we cant do much with that, but there seems to be data in the LDF. Is it possible to extract any data from the LDF file?

Hello,
I was coping database from my sql server 2005 to the same server but with different name. 4 steps completed successfully but the last step failed because the computer on which sql server is running turned off unexpectedly. When the server was running again, the source database was detached. I tried to attached it but sql server is reporting error 5 (system cannot access the specified file) I cannot access the file from windows explorer too. I discovered that the copy of the mdf file exists with the name of the target database but when I try to attach this new mdf file sql server reports that the file is not primary database file. Both files are the same size. What can I do? Thanks

Heya all,
Sorry if this has been posted elsewhere, etc., please point me in the right direction if it has 'cos I couldn't find it!
Right, we have a mirrored database with full safety and a witness for automatic fail over, all works fine, very impressed with it. Now I need to backup the database involved and this is where I could do with some help and answers and/or tips.
As the mirror database is off-line/recovering it seems you can't back that one up, but I'd like to have something that tries to back it up for if/when it fails over and becomes the primary. The solution I've used for now is to write a small .Net application that uses the client side fail over connection string (Data Source=Server1;Failover Partner=Server2) so that it connects to whatever system is currently the primary, and then issues the relevant 'BACKUP xxx' statements to backup the database.
This applications is launched from a windows scheduled task job on the hour (or near to it), every hour. At 06:00 it does a full backup, at 12:00, 18:00 and 00:00 it does a differential backup, and all other times it does a transaction log backup.
This all seems to work fine so far, and generates all the relevant backup files to a share on another server.
So, my main question is; does this look like a good plan? Am I missing some really simple wizard or button that would backup the relevant database from whatever server is up?
Secondly, are the backups from each server interchangeable as they're in a mirrored configuration? That is, for example, the backup application (on the hour) connects to Server1 does a full back up, followed later by a log backup. Server1 then dies, so the next time the backup application runs it connects to Server2 and because of the current time does a log backup from Server2. If we had to restore from backups, could we use the full backup and log from Server1, followed by the log from Server2? Otherwise I'll guess I'll need to modify the logic for the backup application to detect it's failed over, and maybe do a full backup on Server2, or something like that.
Anyway, thanks for any help/advice/tips,
Gareth/OhGod

Hi all,
I am struggling with configuring SSB network routes to a mirror database. What I want to accomplish is to configure a SSB application to work in a database mirroring setup but I am not looking for a load balancing solution.
According to SQL Server 2005 Books Online (http://msdn2.microsoft.com/en-us/library/ms166090.aspx) the typical routing configuration for a service hosted by a mirrored database is set by specifying the 'mirror_address' field but leaving the 'broker_instance' field empty (i.e. NULL) in the sys.routes table (see Example 3 in link above). I haven't seen how this is possible because if you specify the MIRROR_ADDRESS parameter in the CREATE/ALTER ROUTE command then you must also specify the BROKER_INSTANCE parameter.
I haven't found a way to set the mirror_address field to a valid value and the broker_instance field as NULL, is this possible? If not I must set the broker_instance as the guid of my broker instance but my understanding is that it should primarily be used for load balancing configuration. My preference would be to not set the BROKER_INSTANCE parameter, is this possible?
Best regards,
Oli

I have a database I need to copy from a Prod server to a Dev server. There is not enough space on the Dev server. In looking at the size of the files on the Prod server, the Initial Size property for the transaction log on the Prod server is set to 100,000 MB though the log is using nowhere near that.
This is a mirrored database so the recovery model is "full". I know that to change the initial log size, I have to put the database in 'simple" recovery model. Is this possible? Can I just:
1. Pause the mirror
2. Switch recovery model to simple
3. Change the initial size property to something smaller.
4. Shrink the transaction log
5. Change the recovery model back to full and resume the mirror?
I honestly don't know if the transaction log is needed on the Dev server. Meaning I may just be able to restore the transaction log to a different location on the server and delete it so that new one is created.

I have set up mirroring in high availability mode (principal, mirror, and witness).
After setting up mirroring, I needed to adjust the size of a column in one of my tables. I did so with the following command
ALTER TABLE OrderOptimizer.dbo.rCodes ALTER COLUMN CodeDescription VARCHAR(8000).
The column was initially VARCHAR(128)
When I look at the table structure it shows that the column is now VARCHAR(8000), however I can only enter 128 characters into the field.
I forced a failover to look at the table on the mirrored version. It too showed that the column was VARCHAR(8000).
If I open the table I can enter more than 128 characters into the field, however when I refresh, it is truncated to 128 characters,
Any help would be appreciated

Every once in a while a scheduled restore of a production database backup to a development server will fail with the following error.
RESTORE cannot operate on database 'XXX' because it is configured for database mirroring or has joined an availability group
While it is true the production database is involved in database mirroring, the development server does not have database mirroring enabled. This error tells me something within the backup is telling the development server the database is configured for database mirroring.
However the perplexing part for me is that we only receive this error maybe 5% of the time, if that, and only on a couple of our databases. We have numerous other restores of mirrored production databases to development servers that have never produced this error. So my question is what is causing this error to occur, and why is it not happening all of the time? We get around this error by deleting the DEV database and re-running the restore job.

I need some clarification about adding file in to mirrored dataabse in primary server without downtime and breaking the mirror server.
In our environment we are using monutdisks in both the servers. in primary for ex we have F drive for data files under mount disk 3 in mirror server also we have same drive but in mount drive2.
As per my knowledge if it is same drives we can add the ndf files in the primary that will reflect on mirror. but in current situation i am confusing about mount points with different names.

database : MS SQL server ver 6.50.201
problem: server startup / server time out
details
SQL server shows usage of 100 % CPU utilization, if started automatically / manually. and does not proceed / hangs up(server time out), but win nt operates extremely slow.
The background of the situation in brief is as stated below.
The errorlog was found to have the messages
warning : OPEN OBJECTS parameter may be too low.
Attempt was made to free up descriptors in localdes()
Run sp_configure to increase parameter value.
Error : 644, severity : 21, state; state 1
the non clustered leaf row entry for page 2 row 1 was not found in index page 40 indexid 2 database 'tempdb'
Error : 2620 severity 21 state 3
the offset of the row number at offset 32 does not match the entry in the offset table of the follwoing page : page pointer = 0x1395800, page no= 40, status = 0x2, objectid = 1, indexid = 2
Action taken
I used the sp_option to increase the open objects from default 500 to 1000, and the LE threshold maximum value to 400 from the default 200.
after which I used reconfigure go and restarted the computer to take the effect. The following did work fine and server was working ok. But then from yesterday I am having the problem that the MS SQL sever is utilizing the cpu to 98 - 99 % and I am not able to connect to the server.
I tried to start the server with the minimal configuration by specifying the -f option in the service manager start up options, it showed the following message
00/12/07 10:40:49.73 ods Unable to connect. The maximum number of '5' configured user connections are already connected. System Administrator can configure to a higher value with sp_configure.
00/12/07 10:40:50.02 ods Unable to connect. The maximum number of '5' configured user connections are already connected. System Administrator can configure to a higher value with sp_configure.
afterwhich I tried with the option of starting the sql server with the option -c -f
which in the event detail of the win nt shows
"mesg 18109: Recovery dbid 6 ckpt(55813,8) oldest tras= (55813,0)"
The open procedure for service "MSSQLServer" in DLL "SQLCTR60.DLL" has taken longer than the established wait time to complete. The wait time in milliseconds is shown in the data.

The dbid is / was 6 for both the instances, the database which is having this dbid is database name "AM" and is having above 1300 tables (approx)
what could be the problem and solution for it?
kindly help me out of this situation.

Hi
I am in a trouble without doing any mistake. I restarted while in parallely my sql server was restarting i.e I opened a management studio.
When it booted up next time. I see that my database is gone. Though it is showed up in the server but has no node below it.
I then checked the mdf files and ldf files and found mdf file to be of 0 KB and ldf file is of 1.73 GB. My database was in full recovery mode but i did not take any database backup.
Here ais the entry from my SQL server log:
The operating system returned error 38(Reached the end of the file.) to SQL Server during a read at offset 0000000000000000 in file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDATAHello.mdf'. Additional messages in the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.
I wonder if now there is a case to recover my database..Can I restore/recover the database from .ldf file as it was in full recovery model?Any help i shighly appreciated.

is it possible to recover an existing SQL server? Here is what happened. WNT server 4.0 was corrupted, had no backup, repair did not work. consequently, i had to reformat the C drive and do a clean install of the OS.
my SQL files and user databases were on other drives. can i do a install of SQL server and tell is were the SQL server files (ie., the MSSQLDatamaster.db) are and have it use those files? given that this problem occurred as i tried to backup my SQL server database.
hope you can help or my butt is burned!

We are having major hardware replaced on our W2000 Adv Server and we
need to be prepared to restore the entire system.
If the hardware fix goes badly, worst case, the plan is to
rebuild the server and then REINSTALL SS7 and
then restore all the databases from tape backups.
My question is, which database(s) should we restore first?
Should we restore master and then proceed to restore the user
databases or restore the user databases first and restore master last?
Thank you in advance.

Help !!!!
How would you fix these two problems.
1. On the window of Enterprise Manger and under the databases, the database shows one of the databases like this manag_dat(recovering)rather than manag_dat. (manag_dat is the name of the database). What could cause the probem and how to fix it?
2. Same position as above, but instead it shows manag_dat (loading). I tried to delete its device and the database. it hang. How would it happen and how to fix it?
Thank you ahead of time

Any ideas how I can recover a job that has been deleted (?) from SQL7.0 ? We had one which was used on a regular basis which has nowceased to exists. I've spoken to the people responsible for the serverand was met by blank faces (as usual). They have no idea when it wasdeleted, by whom or when. To make matters worse, they don't think theycan get it off the backup set without a major bit of work to theserver. Suprisingly, none of the users noticed that things had stoppedworking.Unfortunately, I needed to do some work on this in preparation for mymonthly meeting with my boss on Monday. Whilst I'm not to blame, I'dlike to understand a little more about any options available to us forrecovery as he will undoubtedly ask when he finds out.I have an old back up on another server, so it's not the end of theworld re-creating it, but I was under the impression it was backed upproperly. Is this normal or have they missed something ?Are there any ways I can recover this ? What can I get done to thebackup to make sure this is backed up properly ?Thanks in advance.Ryan
