ATM Circuit & Sql 70 Warm Backup Servers
Apr 10, 2000
Hello out there.
I am currently testing the transmission rates of sql server 70 backups over an ATM circuit (T3) from tampa, fl to detroit. We are evaluating what we need to do to relocate our warm backup database servers to our Disaster Recovery site in detroit. I have tried several types of transmissions and are not receiving any transfer rates that will reasonably work with a recovery plan. I have tried copying a file from source to target, I have tried backing up from source to target, I have tried FTP'ing files, and never can achieve higher transmission rate then 1 gig per hour.
I am looking to talk to anyone out there that may have implemented a long distance sql servber DR site or anyone who is thinking about it. Or anyone who has any input on how I might be able to achieve a higher transmission rate over a T3. Or anyone who is using SAN's in both their local and DR site and might be using special synchronizing software. I am currently piloting a Metastore SAN and a Compaq SAN to solve some local disk management problems and eventually transmit data from SAN to SAN for DR.
Please, if you are involved with any of these strategies and would like someone to share your knowledge with or if I can be of help to you by sharing our testing knowledge, please write asap.
Thanks.

I think I know the answer to this but thought I'd ask anyway.
I have a conditional split to check a column for null values or empty string values. It looks like this:
(!ISNULL(Ballot)) || (LEN(TRIM(Ballot)) > 0)
My question is: Are both sides of the expression evaluated? My testing says yes, because a Null value causes an error. Is there a way to short circuit the evaluation like the || operator in C# or the (less than elegant, and seemingly threatening) OrElse operator in VB? Whats the best alternative:
A slightly more complex expression that turns a null value into an empty string
A script component
Two conditional splits
Two paths out of one condtional split
I went with the first option, here is the expression I came up with:
LEN(ISNULL(Ballot) ? "" : TRIM(Ballot)) > 0

I am trying to install failover support for my sql server 7.0 database on the in clustere server enviorment
Now We have operating system on two clusterd servers but just one common database disk
Now what will happen if i lose server A ( Active ) the server B will take over and use the same database . But what will
happen if database disk crashes IS it possible for me to replicate the data or use disk mirroring , or have one clustered
database server seperate
How does the database server cluster work ?
What kind of replication do i use for my backup support ?
what should be my recovery process ?
how can i use standby option on the database during recovery ?
Please try to reply as soon as possible
if you can also point to some documetation on the net that will also help
Also look at my current structure ( but this should not affect your answer )
Tables
group 1 --- 20 tables ( being replicated to server c )
group 2 ----60 tables
on cluster 1
Server A-- Holds Group 1 ( Transictional replication to server c )
on cluster 2
server B---(Production server ) Group 2 + Group 1

I am wanting to use backup compression on a few sql servers (2008R2 and 2012). I have never touched compression before and always just gone with the default.I use Ola Hallengren's scripts to do the backups which, if not specifically specified, will use the server default.Backups (FULL and LOG) have been happening successfully on these servers for years.SQL won't care that the previous backup in the set was uncompressed or that the hourly transaction log backups previously taken were uncompressed?Restore statements (T-SQL) will be identical?From everything I am reading it is simply a case of setting the configuration and acting like nothing changed but I just wanted to be 100% certain.1 of the servers is a SharePoint backend.All of the backup files from all servers are picked up by Commvault backup system.

I ran the following code on one of our servers and I got some surprising results. Those results included backups for that machine but also showed entries for other servers. I don't understand it! I can understand the results being wrong because I coded something incorrectly, but why would another server be listed in bs.server_Name? It appears that the entries are "correct" in that backups were taken on the other server at the time given, but why is it there??? (I put the code together to list the most recent backup for each database on the instance. I hope it is correct.)
select @@ServerName, bs.server_Name, bs.Database_Name,
bmf.physical_Device_Name,
bs.backup_start_date, bs.backup_finish_date,
Case When bs.backup_start_date < Getdate() - 1 Then 'Stale' Else 'Recent' End as Status,
Case When bs.backup_finish_date is NULL Then 'Failed' Else 'Successful' End as Success
from msdb.dbo.backupset bs
Join msdb.dbo.backupmediafamily bmf on bmf.media_set_id = bs.media_set_id
where type = 'd'
and bs.backup_set_id = (select max (bso.backup_set_id)
from msdb.dbo.backupset bso
where bso.server_name = bs.server_Name
and bso.Database_Name = bs.Database_Name
and bso.Type = 'D')
order by database_name

Hi,
I am creating a job that runs this command:
EXEC xp_cmdshell 'copy f:dados_sqlmssqlackup
ecom_tb_basico.bak \stalingrado_2c$ emp',
The result of this job is:
"Access is denied.
0 file(s) copied.
NULL"
But I am running this command with sa user.....
Wich kind of permission is missing to execute this copy?
When I execute the same command to copy the backup from the server to itself, it works fine!!!!
Does someone have an idea to solve this problem?????

Hi,
I have been experiencing a problem with a job I am trying to automate. My team requires two instances of a db on development. Every week, db1 is detached and reattached as db1_copy, and a new copy of db1 from production is copied over. I have used cursors for the dropusers, addlogins, grantdbaccess, addroles, and addrolemembers aspects of the restore process. Also, we use sql authentication and not windows authentication. The issue is that when the agent encounters a minor issue, ie. a login that already exists in that db, or adding a rolemember to a role that is already there, I get an error. I have ensure that at that step, the job simply proceeds because it is a minor step in the process (it happens during the script execution when done manually but I can override this because I am present and just let it run in one step instead of many). Is there any way to do this without adding a multitude of steps?
Thanks,
Maria

We are told that we cannot get remote access on our DB servers , can access them only via SQL management studio. But we are the one's who will be restoring all our DB's from current setup to new servers.
My Question:
1. Can we restore the DB's directly via SQL Management studio(from other server where management studio is installed) without logging into the DB server.
2. How do we set the mdf/ldf file paths, assuming we have elevated access on the DB. Is this possible?.
Any other blockers we can face?

We are planning to provide a disaster recovery facility for a production system. Clustering has been ruled out for technical reasons so we are considering either transactional replication or Log shipping.
Microsoft suggested the log shipping option but it seems a bit messy to me and only provides a warm standby in that it only copies log backups to the secondary machine.
Any ideas why log shipping was suggested in preference to transactional replication? Anyone have any experience in this area?
TIA Colin.

I have inherited a problem that I am hoping someone can help out with. A developer used a perl script to move some backup files from one server to another and then restore the databases on other server (at least we think that is what happened, no one is really sure at this point)
Now I need to take the databases ourt of read only mode and drop them but I get an error 5063 stating that the database is in warm standby and the alter database and sp_dboption statements both fail.
How do I get the databases out of warm standby mode?
Thanks in advance for any help you all can provide.

Hi,
I have one database with read-only status. I tried to change it back to normal by doing this..
EXEC sp_dboption 'test', 'read only', 'FALSE' by doing this i'm getting this
Changes to the state or options of database 'test' cannot be made at this time. The database is in single-user mode, and a user is currently connected to it.
And when i tried on Enterprise Manager it is saying
Error 5063 database 'test' is in warm Standby.
I cross checked and confirmed that it is not in single-user mode and no one is connected to the database!!
Any help is greately appreciated.
thanks

Because the IIS threads are recycled at night, the first user that calls up Report Manager in the morning has to wait 30 seconds before the page loads, as IIS is creating a thread.
I'd like to set up a job in SQL Agent that will navigate to http://localhost/reports/ every morning before users come in to work, so they won't have to wait.
I think a SAL Agent job of type ActiveX Script would be suitable for this, so I need to write the code to navigate to the reports page in VBScript.
Anyone knows how to navigate to a page in VBScript ?

I have a report that was designed using SQL Reporting Services that sits on a SQL reporting server. It's nothing too exciting, it is essentially a three page application with legal jumbo on pages 2 and 3 and applicant data in fields on page 1.
We use rectangles to force page breaks to page 2 and to page 3.
When running the report on the report server, it shows and prints fine.
When running the report from the QA website internally, it shows and prints just fine.
When running the report from the production website from a machine internally, it shows and prints just fine.
When running the report from outside of the company network, the report is jacked. It obliterates large chunks of text, crams text together, and creates blank pages.
I need help in determining where I even begin with trouble shooting this!

can anyone tell me if they know of a way to automate the update process from development servers to live server, with little interference from an administrator
I have a development team that are constantly updating their databases along with their ASP code, and want to publish changes an a weekly basis. They have asked me for a way to take their new structures, tables, procedures etc, and copy them to the live servers, but NOT to interfere with existing customer data.
Funny I know – and I hate the idea btw :(
Any references, contacts, 3rd party tool recommendations welcome,
Thanx,
Darren

I am in the middle of a major migraton project, moving from x86 SQL 2000 to IA64 SQL 2005. I have a business need to link to several legacy servers. I have a number of problems I am trying to solve.
1) Linking a Kerberos server to a non-Kerberos server.
2) Linking x64 or IA64 servers to x86 servers.
3) Linking SQL 2005 to SQL 2000.
Two of the errors I am encountering are:
------------------------------
TCP Provider: An existing connection was forcibly closed by the remote host.
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
OLE DB provider "SQLNCLI" for linked server "SCDC250DB" returned message "Communication link failure".
(Microsoft SQL Server, Error: 10054)
------------------------------
And
------------------------------
The OLE DB provider "SQLNCLI" for the linked server "SCDC250DB" reported an error. Authentication failed.
Cannot initialize the data source object of OLE DB provider "SQLNCLI" for linked server "SCDC250DB".
OLE DB provider "SQLCLI" for linked server "SCDC250DB" returned message "Invalid authorization specification".
(Microsoft SQL Server, Error: 7399)
If someone has worked through these problems before, I would appreciate it if you could direct me to the relevant documentation to resolve these issues.
Thanks!

Hi there
I'm getting this message on my third automated backup of the transaction logs of the day. Both databases are in full recovery mode, both successfully backed up at 01.00. The transaction logs backed up perfectly happily at 01:30 and 05:30, but failed at 09:30.
The only difference between 05:30 and 09:30's backups is that the log files were shrunk at 08:15 (the databases in question are the ones that sit under ILM2007, and keeping the log files small keeps the system running better).
Is it possible that shrinking the log files causes the database to think that there hasn't been a full database backup?
Thanks
Jane

On the SQL Server the Event Viewer shows the same messages and errors every evening between 22:05:00 and 22:08:00. The following information messages are shown for every database:
"I/O is frozen on database <database name>. No user action is required. However, if I/O is not resumed promptly, you could cancel the backup."
"I/O was resumed on database <database name>. No user action is required."
"Database backed up. Database: <database name>, creation date(time): 2003/04/08(09:13:36), pages dumped: 306, first LSN: 44:148:37, last LSN: 44:165:1, number of dump devices: 1, device information: (FILE=1, TYPE=VIRTUAL_DEVICE: {'{A79410F7-4AC5-47CE-9E9B-F91660F1072B}4'}). This is an informational message only. No user action is required."
After the 3 messages the following error message is shown for every database:
"BACKUP failed to complete the command BACKUP LOG <database name>. Check the backup application log for detailed messages."
I have added a Maintenance Plan but these jobs run after 02:00:00 at night.
Where can I find the command or setup which will backup all databases and log files at 22:00:00 in the evening?

SQL Server 2008 r2 - 6 GB memory...I attempted a backup on a 500GB database but it was taking way too long. I checked the resources on the box and saw the CPU at 100%. I checked the SQL Server activity log and saw a hung query (user was not even logged on) that had multiple threads so I killed it and now the CPU utilization is back to normal.
Trouble is, now all of the threads in the activity monitor for the backup show 'suspended' and the backup appears to be not doing anything.

Hi,
I use the Transact-SQL BACKUP statement in Visual Basic to backup my local MSSQL Database. It give me this error
Error 3041
BACKUP failed to complete the command BACKUP DATABASE [BCFPC] to BCFPCBKP
I already created a backup device called BCFPCBKP and it is backup to the disk.
I tried to run the same BACKUP statement in SQL Query Analyzer and it worked fine. I tried to run my VB application in another PC. It worked fine when i use this command remotely. Can anyone tell me what's the problem?
Thanks in advance

Using Ola Hallengren's scripts I do a full backup of a database on a Sunday. Then differential backups every 6 hours and log backups every hour. I would like to keep a full week of backups based off the full backup done on Sunday. Is there a way for me to clear out the diff and log folders after the successful full backup on Sunday nights?

Windows 2003 backup utility uses the shadow copy option that allows it to copy open files.
Therefore, can I use this utility to backup the .mdf and .ldf files for my SQL 2000 database?
I can then attach the .mdf files if I need to restore the database to another server.
Can anyone tell me if this is safe? I've tried it and it worked but I'm worried there maybe some lurking danger in using this approach.

We take a full backup in the early morning and hourly transaction log back during the working hours for one database in the production server. The application team made certain changes to the design of the said database in their development server. The backup from the development server was restored to the production server during working hours. After the restoration should we take a full backup before next transactional logbackup? Would the transactional log backup with out a full backup after the restoration of a database be valid?
