Hello,
this is my configuration :
1) 3 disks in RAID5 that hold the SQL data
2) 1 disk in RAID0 that holds the only paging file.
What will happen to the SQL data (DB) when the disk that holds the paging file crashes?
Kindest regards,
Luc.
hello,all
I am new to Sql 2000,I installed sql 2000 database in C disk,but Now I found my C disk space is smaller than before,So I want to move my databse(include data and structure) from C Disk to D Disk(its space is very large) .
is it possible to do it ?
if its can be done ,do I need to change my asp.net program source code (exp: chaneg my crystal report connectstring ) ?
thanks in advanced!
Cristiano writes "hi everybody.
A customer of mine has had a disk "crash" few days ago.
I wrote for him a dwh application and
of course the backup was not working...
now some "hardware guys" said that it is possible to recover most of
the files.
what I need to restore would be:
1- the sql server db
2- the sql server dts and jobs
3- the analysis service cube and dimensions
to do so is it enough for me to have:
1- the .mdf and .ldf files
2- the master.mdl /.ldf file
3- the .odb file and .dim* and .role .map ... files
right?
is it enough to recover everything?
if it is so, what would be the right processes to recover everything? "
If I return the Average, Minimum, and Maximum values for the counter Physical Disk: Avg. Disk Queue Length, and those values are 10, 0, 87 respectively, which value do I use to compute the Avg. Disk Queue Length for a 4 disk array(RAID 10): Average, Minimum, or Maximum? The disk(lun) is on a SAN.

Hello,
I am trying to setup a test cluster and am having an issue. When I try to create the resource of a physical disk it takes both the drive e: and drive q: and doesn't seperate them into two physical disks as resources. This means when I try to associate the quorum disk it links the to physcial disk resource of drive e and q. Then when I try to install SQL2k5 I get the warning about installing SQL on the quorum disk. Am I missing something? Is there a way to seperate e and q onto two physical disk resources so I can specifically associate the quorum to q and the sql to e or should I be setting the quorum disk to a majority node set? Thanks in advance.

Hi all,
Ok here goes,
I have a three tier system using SQL server 2000, we are currently experiencing IO bottle necks on our SCSI Raid 10 array, which holds the Data and the logs in separate partitions.
So my options as I understand it are:
Get Enterprise edition
or
Get another physical raid 10 array and separate the logs and data i.e. data on one array and logs on the other array.
I would like to try the latter but I am totally unsure how much difference this will make or whether it will make any difference at all.
Does anyone know how much performance increase I will get from using two arrays as opposed to one?
Any other advice on this scenario would be greatly appreciated.
Thanks
Hi,
I am trying to create a scheduled task taht will restore a database from a backup file. I do not store my backups on a backup device, but on a local disk. To restore a DB from a backup device, the following statement will work:
"Load DBName from BackupDeviceName". Does any know what statement to use to restore from a file, if the file is "E:DBName_db_dump_199909272220".
Thanks in a advanced.
It's probably a really easy thing to do, but I can't find out how to do it, so hopefully somebody can spare the time to help.
I want to read in T-SQL contained in a file held on disk and execute it in a stored procedure.
Anybody know how to get the contents of the text file into a variable so I can exec it ?
Thanks for your time.

I am getting occasional failures of a SQL Server 7.0 complete backup to disk on a production database. The errors seem to indicate that another process has the disk file open at the time of the backup. The errors contain the following texts : -
'Cannot open backup device'
'Operating System Error=32 Process cannot access file because it is being used by another process'.
The only other process that should access the disk file is an ARCserveIT scheduled job to copy the disk backup to tape but this is completing long before.
Any ideas or suggestions?
Hi All,
One of the drives that stores the database file is close to running out of space. The chance of me getting more space added to this drive any time soon are really low. What are other options I have?
Thanks.

Hi all,
I have to give support to this new client of ours and the system out there was a real mess.The log files for all four databases were ranging from 5 to 9 GB's, no maintanance no nothing was done since the setup of the system. I have truncated the logs after taking proper backups since it all started after they compalined a DTS was not working, which was due to no disk space available ;).
Now I have to shift the log files to a seperate disk.
I know it can be done by detaching the database and attaching it back, I was wondering if we can do it without bringing the system offline?
Anycomments welcome.
Thankyou.
regards,
harshal.
Hi everyone,
Due to running out of disk space and reducing I/O contention, I plan to seperate data files and log files to different disk arrays.
My plan is to
- detach all databases
- copy log files to another disk
- attach all databases
The total size of log files is about 60GB. It becomes a problem becasue it spend too much time passing files. To reduce down time, is there any way I can do?
Can I just create new log files and remove the current files by using sql management studio?
any other suggestions? Thanks in advance
Hi,
I'm trying to write a restore script. In the past I've always used the SSMS GUI to restore. When running the script below, the process got stuck at around 90%. Eventually I aborted the restore and found out that my C drive was full. The log file of the database I was restoring was 32GB. Can anyone tell me what I'm doing wrong? Thanks.

I have a poorly performing SQL box.
I have run perfmon and the avg read queue length is pretty much permanently maxed out at 100%.
I have run a database index defrag.
On further inspection the file system is highly fragmented. There is a file fragmentation of 98% with the mdf file fragmented in 25,000 pieces. Running a standard windows defrag does not resolve this.
Two questions?
1- Is heavy file fragmentation of the MDF file a likely cause of the read queue length bottlneck?
2 - Why is the MDF file not defragmenting? Does the SQL server have to be taken offline? Is it possible to defrag a MDF file?
catcat writes "Hi All,
Our MSSQL 2000 server crashed yesterday and one database cannot be restored. the latest backup we have is june. We can only recover the MDF file from the harddisk and according to our admin, it cannot be restored anymore because no proper shutdown was made.
Will appreciate your help here."
Hi all
My Transactional log size increased to 39GB, it is in full recovery mode,
To regain the space, i have done the following
BACKUP LOG DB_NAME WITH TRUNCATE_ONLY
DBCC SHRINK_FILE (LOG_FILE_NAME,500)
But not able to regain the space in the hard disk.
No Transactional backups to truncate the log file were setup.
Can you please tell me why the space was released and what should i do further to clean up the sapce
In SQL Server 2005, via the GUI, I wish to backup a database to an additional disk file (there is already an existing backup disk file for this database), so that I can have more than one backup. I've added the new disk file name, highlighted it, and clicked OK.
I get an immediate error (see below). Note, the 2nd error message is specifying the existing backup disk file, not the new one I'm attempting to create.
"Backup failed for Server 'WCS-DEV-TPA'. (Microsoft.SqlServer.Smo)"
"System.Data.SqlClient.SqlError: The volume on device 'D:Program FilesMicrosoft SQL ServerMSSQLBACKUPWCS_ADV_Longmont.bak' is not part of a multiple family media set. BACKUP WITH FORMAT can be used to form a new media set. (Microsoft.SqlServer.Smo)"
Does anyone know what causes this and how to correct it?
Do you have to move the entire content of the log folder to the new location?

Summary: We host reports off of one server that are accessed and refreshed 24/7/365. On a daily basis, I receive calls about reports taking several minutes to run IF they run at all. (normally these reports take seconds). There has yet to be an actual "error message" associated with this behavior. When I check the server at these times, I will find that w3wp.exe process is taking up about 4G and is causing paging. It seems that once it gets to that point, it will kill itself and all goes back to normal. However, it's a slow death and is impacting business.
We're using MSRS 2005. Hosting the reports is the job of this server--no other applications are hitting it. There is a development SQL db on the box, but not in use at this time. The datasources in most cases are stored procedures housed on another box. The web interface (for end users running the report) is hosted on a third server.
Any thoughts?

We will move t-log from one disk to another one. I tried Alter Database and found it did not work for log.
Can somebody give me a method about moving log from different disks?
Thanks.

Does anyone know how to get the free disk space for all drives in many different SQL servers.
I need to populate a report (right now output in Excel) with the free disk space of all drives on all of my SQL servers.
I found xp_fixeddrives but that is specific for the server where it is executed.
Any help or pointers to a script in the archives is much appreciated.
Thanks.

We need a drive cloning app, like Ghost, that will allow us to transfer a production image off of a HDD to other PCs. The problem with this is that
our production needs SQL in order to run and transferring the initial image to uniquely named workstations causes DB registration problems. Is there
an app that will allow us to configure this transferred image so that SQL will refer to the "new" drive instead in of the "old"?
