Time To Manually Failover?
Mar 8, 2007
When I force Mirroring to fail over while watching the Mirroring Monitor I notice something interesting. Before I failover, the servers are synchronized and there is zero unsent log and zero unrestored log. When I failover, the mirror changes to "restoring", stays there for about four minutes, switches to "Principal, restoring", and then the unsent log and unrestored log numbers jump to values in the tens of megabytes, and we spend time restoring.
We wait about five minutes between requesting the failover and having the servers back up again, answering requests.
Why does failover take so long? We've been thinking that failover shouludn't take so long because the servers think they're synched. What causes the log spooling spike? Is the state refelcted by the mirroring monitor inaccurate?

Hi,
I have a package designed as bring data tables over to SQL Server. There are 9 data flow tasks that runs parallel, to bring 9 datatables over. In BIDS, when I execute the package, it runs like 8 minutes. Or if I start the scheduled job manually, it runs around 8 minutes too. But it runs about 30 minutes at the scheduled time at midnight.
I wonder what I can do to speed up the scheduled job.
Thanks

Hi All,
Is it possible to reduce the automatic failover time on MS SQL 2005? It seems to take around a minute on my servers.
Thanks for your help.

1. Once fail over to secondary replica, what will happen to connected session in primary node? can the session fail over to secondary seamlessly or need to re-login. what happen committed transactions which has not write to disk.
2. Assume I have always on cluster with three nodes, if primary fails, how second node make write/ read mode.
3. after fail over done to 2nd secondary node what mode in production(readonly or read write).
4. how to rollback to production primary ,will change data in secondary will get updated in primary.

We have set up Mirroring with a witness server and everything works fine when we failover from the SQL Management console.
However, if we failover when our Maccola client is connected, the client blows up - clearly because it can no longer connect to the database.
The ODBC DSN used by the Maccola client shows a checkbox for the 'select a failover server' but the checkbox is grayed out.
Also the summary of settings for the DSN at the end of the wizard reveals that the failover to server (y/N) option is set to N.
The default setting for this DSN is 'populate the remaining values by querying the server' but it doesn't appear to be getting the settings for failover from the server or any other interactive DSN settings either. The server is clearly set for mirroring.
Another suspicious item is that the DSN cannot connect to the server with SA permissions, even though the server is set to mixed security and we use the correct authentication.
Is it possible that the client MACHINE is not authenticating with the domain or sql server properly. We are logged into the client with the domain account that is the SQL admin account on the sql server box.
We should be able to interact with the sql server settings through the ODBC DSN on the client shoulnd't we?
Are we missing a service pack on the client?
Thanks,
Kimball

Hi All,
This may sound quite easy for you, however I am a newbie in SQL.
So I have an identity field, which I wish to increment automatically every time I do an insert. However the starting integer has to be the MAX value from another table.
So for example I am doing an insert in a #temp table
INSERT INTO #temp(name, surname)
SELECT name, surname from table1
Now the personId of the #temp table has to start from the MAX of table2
Ie SELECT MAX(personId) from table2
The SELECT MAX(personId) from table2 can also be NULL, ie the first time I am inserting, so I also have to cater for this scenario.
can anyone help?
Thanks
Johann

There is only on Database (DB) of 16 Gb in drive G.
Drive G has 32 Gb space free.
Yesterday we appended tables to the database and in SQL logs appears the next error:

DB configured to grow automatically by 100 Mb and transaction log Automatically grow in 10% .
Unrestricted file grow selected on both.
I try to expand the DB manually by Enterprise Manager to 20 Gb but not work and in SQL log appears the error
"2003-01-23 12:26:48.03 spid101 fcb::ZeroFile(): GetOverLappedResult() failed with error 2."
In Enterprise Manager-Databases-Properties-General-Size of DB maintain 16Gb.
Windows explorer say MYDATABASE.MDB is 20480 MB.
I delete the tables inserted and the problem persist.

I've been studying/experimenting with the replication features and though the Updating Susbcribers Replication Model was the answer to my data environment.
What we want: We have a live server (Publisher) that'll serve content to our users, but we want an "offline/data entry" server (Subscriber) that'll pretty much have the exact same data as the live server for data entry and validation purposes. Changes and inserts would be done on the Subscriber locally, vetted through, and once done, it'd be updated to the Publisher.
I've managed to get some semblance of the above working, but the updates are nearly instantaneous. Which means that changes/inserts that may be erroneous on the subscriber machine would almost always be seen on the publisher machine before our operations can do anything about it.
Is there a way to configure the replication process to hold off until the admin triggers it? Or am I using the wrong feature?

Hi all
I'm trying to use the Slowly Changing Dimension transformation and it seems that in order to get the transformation to work as expected the custom property "sql command" has to be manually changed so that a "RTrim" function is applied to all string columns referenced. As an example consider this:
SELECT Initials, Department_Name from dimEmployee
has to be changed to
Select RTrim(Initials) as Initials, RTrim(Department_Name) as Department_Name from dimEmployee
where Initials is the "bussines key" and "department_name" a historic attribute.
Is this the normal behaviour ??

Hi,
I have a table
Code Snippet
CustomerDetail
customerid
customername
status
app_no
deskno
Now everytime a new customer is created, i allocate the deskno. The logic I use is
Code Snippet
create proc spoc_incrementdesk
as
DECLARE @deskno int
select @deskno = (SELECT max(deskno) from customerdetail)
Insert into customers(1,'rick',1,23232,@deskno)
If there are already records present in the customer table, it works well. However if the very first record is getting inserted it inserts null in the deskno because when no records are present (max(deskno) = null).
At time time of insertion, how do i check if @deskno = null and allot it 1.

Is there a way to do this? It would be useful to test whether a subsciption works. At the moment I am setting the scheduled time a few minutes ahead and waiting for the report to run.
Subsciptions are also a convenient way to store different parameter settings for a report.
My preference would be to to do this through the Report Server UI (presumably from the subscriptions tab).
Alernatively, being able to call a report (with paramters) from a stored procedure woukd be useful.
Thanks,
Dick Campbell

Hello,
I use Reporting Services in my solution. The data i have as source is very uncertain. Sometimes i manually have to delete a record from the report (not the database itself). I woluld like to have a checkbox or something simular to delete from report and totals, grafs would be updated. At the same time I would like the report to make a comment that a record was taken away, alternative let the user make a comment. Is this possible? DO i have to make a own application for that?
Thank you for your help!
Best regards,
Luskan

Hi all,
I have created a report in SSRS 2005 which is being viewed by users from different Time Zones.
I have a dataset which has a field of type datetime (UTC). Now I would like to display this Date according to the User Time Zone.
For example if the date is August 07, 2007 10:00 AM UTC,
then I would like to display it as August 07, 2007 03:30 PM IST if the user Time Zone is IST.
Similarly for other Time Zones it should display the time accordingly.
Is this possible in SSRS 2005?
Any pointers will be usefull...
Thanks in advance

Hi, I have limited control on the server I use. I can not create data bases but can add tables and edit the data base that has been created for me. So what I would like to do is be able to use a tool such as aspnet_regsql through SQL Server Express to add the tables that Membership would automatically create. Any help in pointing me in the right direction would be great

I've mined countless threads all over the Net where people are having my problem, but none of the solutions I've seen seem to apply.
When I run a DTS package from Enterprise Manager, everything works great. When I schedule the same package as a job, it fails immediately and reports this error:
Executed as user: SERVER-NAMESYSTEM. DTSRun: Loading... Error: -2147221005 (800401F3); Provider Error: 0 (0) Error string: Invalid class string Error source: Microsoft Data Transformation Services (DTS) Package Help file: sqldts80.hlp Help context: 713. Process Exit Code 1. The step failed.
My hunch is the SERVER-NAMESYSTEM.DTSRun account doesn't have sufficient privileges, but I can't find how/where to fix that.
Help, please.
Thanks,
Doug

Hi guys,
You know when restoring a database in SQL Server, exclusive access is required. With sp_who I can see the clients. But I don't know how to terminate the client connections easily. Usually I have to stop the server and restart it. I DO think it's too troublesome. Do you have any ideas? Is there any sp or command, or tool that may help? How do you deal with this issue?
Thanks!

Hello,
I've heard rumors of best practices to include manually stopping SQL instances before doing a reboot of the system. Is this true and if so, where is this documented. I've searched all over and come up empty. So I was wondering if this was just some old DBA saying but no longer relevant?
Thanks

Hi Andrea,
I have made a table which contain data inserted manually and also data that was inserted by using bulk insertion. I have no problems using the table with Grid View. But when I try to use a query like the following:
SELECT *
FROM dbo.last
WHERE VMake = 'Honda'
AND VType = 'sedan'
AND VColor = 'Red';
I would only get the data that were inserted manually.
When I use the same query to filter data from a table that the data was inserted by using bulk insert, I get column names but no data.
Any help please.
