Pause And Resume Mirroring
Dec 5, 2007
If we have a situation that the Mirror server is unavailable for a day....very unlikely, but it happens when servers are moved from one data center to another....Lets assume we are doing safety off (high performance mode)
Should we pause mirroring on the principal server?
When we pause, does the transaction log keeps growing ?
Can we backup the logs ?
If we don't pause mirroring
Does the transaction log keeps growing ?
Can we backup the logs ?
What we can expect we we bring online the mirror server next day! will there be any performanbce problems since mirroring will try to catch up....
Considering moving to mirroring from logshipping for our disaster recovery.
Thanks,

Is there a Pause command in SQL that can be used in Query Analyzer between select statements to press any key to go to the next statement.

Does TSQL (2005) have a way to pause the current batch for a given number of seconds? This would be helpful during testing.

Hello,
My users often view some report for some minutes and after that want to return to parent report.
If they did it after small time (~less than minute), everything is OK. But if this pause is above 1 minute they receive "Runtime Error" message and can only to go to homepage.
I think that this is some session time or something like that.
Am I right? How can fix it?
Thank you

For some reason the status lights in my Enterprise manager are no longer working. I am connected to the databases, but because the indicator lights are not working, I can`t get a quick visual status of my servers.
Any way to get my lights back on?

As part of an ETL process which takes several days I need to build in an auto pause on processing with no set time for restarting it again. So we cannot use the script..WAITFOR DELAY '00:01:00'
Apparently the Loop is not an option as it uses too much CPU.We need to run a few manual checks and there is no way to determine the amount of time needed. After these check are done I need some way of resuming the package from where it stopped.
The obvious way probably is to build this into two separate packages but this would break the logical way our containers are being setup, in other words, it would make us break a container into two different parts in different packages.

Often when I write a stored procedure, I encounter a situation where
it will be really convenient if I can ignore an error and continue the execution
of next SQL statement, especially when I know what kind of error it will generate.
It's just like the effect of "On Error Resume Next" in VB.
Does anyone have any idea or have some knowledge to share?
I would really appreciate.
I am using SQL Server 2005 and SQL Server 2000. Thanks.

The secondary server for my availability group was recycled. When SQL Server came back online the data movement for a database was suspended. The error log shows:
"AlwaysOn Availability Groups data movement for database 'XXXXXXXXX' has been suspended for the following reason: "system" (Source ID 5; Source string: 'SUSPEND_FROM_RESTART'). To resume data movement on the database, you will need to resume the database manually. For information about how to resume an availability database, see SQL Server Books Online."
I was able to resume data movement with no issue. I would like to understand the technical reason as to WHY the data movement was put in the suspended state and left there upon recycle. I searched for an article that would list possible reasons (BOL, Google, Bing, etc..). I just could not find much information out there on 'SUSPEND_FROM_RESTART'.

Hi,
I am trying to create an asp.net web recruiting application for HR, which will give the users the ability to both copy/paste the Resume and cover letter in textbox and upload resume and cover letter, then submit it (which will be saved into SQL Server 2000 table).
I am thinking to save Resume and cover_letter as Image data type columns in SQL Server.
. Can someone give me a direction about how to save the uploaded resume and cover letter to table and if it's the easiest way to do it?
. What to deal with different formats of uploaded resumes? I hope to limit to only Word or HTML
. Since I also give user another option - copy/paste the resume and coverletter into a textboxes. Can I simply save the copy/paste resume and cover letter into text field column? Later, say, if any HR recruiter retrieve the text from database, will it concatonates everything together without line break?
Any ideas is appreciated.

Hello-
A customer has reported getting the following excpetion in our logs, and I have never seen it before and wanted to see if there was any insight you could provide to understand when you throw this exception.
The process is a "purging" process- it just executes a sequence of DELETE statements that should be fairly simple (delete a number of records from a table and CHECK some constraints, no cascading), after the sequence it commits. All of this occurs on the same connection. We use c3p0 for connection pooling.
Here is the exception:
2008-03-22 08:30:08,699 WARN impl.NewPooledConnection : [c3p0] A PooledConnection that has already signalled a Connection error is still in use!

Hello All,
I am developing a package using SSIS which needs to do the following.
1. Read all flat file from a folder. I am doing this using For Loop task. I know the total number of files in that folder hence I am setting the loop counter = file count.
2. The next step is to import the data from flat file to SQL server destination table using data flow task.
3. Upon successful completion of data flow task there are some other tasks like SQL to do some checks/validation on the data, export it to another tables.
Upon successful completion of step 3 the iteration goes to next file.
I want to achieve the following
IF step 2 has error (for example corrupt file or incomplete data), I want to fail data transfer completely, skip step 3, and go to step 1 for next available file and do rest.
How do I do this in SSIS?
Thanks for your help.

Hi,
We recently migrated our application from SQL Server 2000 to SQL Server 2005 and we also migrated from WAS5 to WAS6.
We are getting the following exception when we call any of the stored procedures.
The server failed to resume the transaction. Desc200000003.
Basically we call these stored procedures frequently using the Java thread scheduler.
We didnt face any problem when we use IBM drivers
I guess this is the problem with the drivers.We use JDBC 2005 driver Version 1.1.
But we didnt face this problems when we use JDBC 2000 driver when we used to connect to SQL Server 2000
The Microsoft says that it has fixed the date problems as well as the transaction problems in the version 1.1.But still are facing the issues.
Can anyone of you please help me in getting the solution for the same?

I have a table having 220 lakhs of records and one of the column is Full Text enabled.We have used ContainsTable() to search for data, but we are unable to get results as expected. so we done rebuild.During Index Rebuild, population is failed.I have found this error in error log and it is saying to do resume population.So I want to know how long it takes to complete Resume population process.
look at the below more details about FT Index table.
Row count - 22155112
Index space - 1,903.250 MB (1.9 GB)
Data space - 87,552.258 MB (87 GB)
sqlserver2008 R2
and the below query we have used
HTML Code:
SELECT Distinct top 50 cal.case_id,cal.cas_details
From g_case_action_log cal (READUNCOMMITTED)
inner join containstable(es.g_case_action_log, cas_details,
' ("235355" OR "<br>235355" OR "235355<br> ") ') as key_tbl on cal.log_id = key_tbl.[key]
Where cal.product_id = 38810 ORDER By cal.case_id DESC
This query is not going to search in recent inserted/updated rows. this is the actual issue we are facing.
how to fix this error and if population need to be resume, then how long takes to do resume population.

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?

We have the following scenario,
We have our Production server having database on which Few DTS packages execute every night. Most of them have Bulk Insert stored procedures running.
SO we have to set Recovery Model of the database to simple for that period of time, otherwise it will blow up our logs.
Is there any way we can set up log shipping between our production and standby server, but pause it for some time, set recovery model of primary db to simple, execute DTS Bulk Insert Jobs, Bring it Back to Full recovery Model AND finally bring back Log SHipping.
It it possible, if yes how can we achieve this.
If not what could be another DR solution in this scenario.
Thanks Much

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....

Hello All,
I have a SSIS Package with a "Execute Package Task" to call a child package. I am trying to have the master/parent package complete its execution regardless the outcome (failure or success) of the child package. The overall structure of the master package is:
1. Perform Pre-load tasks (stored procedure).
2. Execute Package Task (call child package)
3. Perform Post-load Tasks (stored procedure)
I have try everything and cannot get the results that I want... I have tried the combination of "failparentonfailure", "forceexecutionvalue", etc. The master package stops at childs failure. I would like to resume to completion
Any ideas out there?

Hi All
By mirroring I mean device mirror, since I do not think that there is a database mirror
We only have disk mirror. I also know that SQLServer 7.0 does not provide Mirror, unmirror or remirror. and for this we have to refer to Windows NT disk mirroring.
I need mirroring in both versions SQL Server 6.5 and 7.0
I want to have mirror on another server. I need this for tonight.
Sincerely.

I hereby let u know the steps that i undertook for performing mirroring
1. Created a database in Principal server named Mirror1 and one table named tblMirror1.( no values inside the table)
2. Repeated the same in Mirror in Witness
3. Selected the Principal server's database -->right click-->tasks-->mirror
4. from the left hand panel selected Options -->recovery model-->full
5. selected Mirroring from left hand panel-->configure secuirty-->entered mirror and witness name--Success
6. When I click on start mirroring I have an error stating
" Alter failed for database mirror1"
"Database mirroring cannot be enabled because Mirror1 database may have bulk logged changes that have not been backed up etc...."
7. followed this one
BACKUP database mirror1 TO DISK='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBackupmirror1_FULL.BAK'
got the answer as
Processed 160 pages for database 'mirror1', file 'Mirror1' on file 2.
Processed 1 pages for database 'mirror1', file 'Mirror1_log' on file 2.
BACKUP DATABASE successfully processed 161 pages in 0.318 seconds (4.147 MB/sec).
According to sources
Run a restore of this backup on your mirror.
This can be done through the GUI or using a T-SQL command.
The database restore must use the NO RECOVERY option, so the database stays in a loading state.
Also the database name on the mirror must be the exact same name as the principal
RESTORE TestMirror FROM DISK='C:Backup TestMirror_FULL.BAK' WITH NORECOVERY
Hence did the below
RESTORE database mirror1 FROM DISK='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBackupmirror1_FULL.BAK' WITH NORECOVERY
ERROR
Msg 3201, Level 16, State 2, Line 1
Cannot open backup device 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBackupmirror1_FULL.BAK'. Operating system error 2(The system cannot find the file specified.).
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.
HENCE MODIFIED AS
use master
go
RESTORE database mirror1 FROM DISK='C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBackupmirror1_FULL.BAK' WITH NORECOVERY
Msg 3201, Level 16, State 2, Line 1
Cannot open backup device 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLBackupmirror1_FULL.BAK'. Operating system error 2(The system cannot find the file specified.).
Msg 3013, Level 16, State 1, Line 1

i am for the first time creating the database mirroring.I am moving the all the usr databases and everything from test server to a new server called test1.And from that new server i am restoring on the another new server called test2 for database mirroring.But in the test server , the transaction logs are backup for every 15 minutes.So in this case is there a need to move all the logs to test1 and then to test2 for mirroring?? or there is no need to move transaction logs to the new servers at all??
my secnario
------------
server1 server2 server3
-------- ------- --------
test test1 (moving everything from test) test2(mirror for test1 )
all the transaction logs are backup in test for every 15 minutes. so in this case , do i need to move the transcation logs from test to test1 and test2

Hi All,
I am trying to set up database mirroring and in the initial phase of database restoring im getting some problem.
the scenario is .
1- I create a TestMirror on server1(which will be principal server) and backup full and transaction logs.
2- create TestMirror in server 2( Which is going to be used as mirror) .
3- restore the full backup of "TestMirror" from Principle Sever with NORECOVERY option.
this step results in a message box showing that the restore was successfull...
but the database explorer( management studio) shows the TestMirror in (restoring ...) state. and no more operations can be performed with this Database. ( because the database is in restoring mode).. please help what this issue is?
Thanks In Advance for any suggestions
