Placing Tempdb BACK On Disk
Jul 23, 1998
Our development server is limited on RAM and I have been asked to increase Tempdb. I made the decision to put it back on disk; something I have done dozens of times before. I have used the Enterprise Manager`s GUI interface and I have manually typed in the SQL using ISQL/w, both ways have resulted in the same error message.
Microsoft SQL-DMO
Error 5016: [SQL Server] Incorrect database name or device name(s).
I have dropped the old and created new database devices (with different names) and I still receive the error message. I have even tried rebooting with Tempdb back in RAM and on disk 1t 2MB (which works). And yes, I HAVE checked my typing.
I would GREATLY appreciate any ideas on what may be wrong. The system is 6.5 with SP4 on Win NT with SP3. I inherited the system, so I am not certain what the hisory is.
Thanks,

I try to find some feedback regarding setting the TempDB files on a RAM disk.Specifically I am looking for "production results" that could show the difference/benefit of such an usage.The tests on physical server and VM I already made have shown a boost in overall SQL Server 2012 performance on SQL Server instances housing data for SharePoint 2013 and Dynamics AX 2012 R2.Graphic below show differences between 5 different configuration on the same physical server:
- Physical HD: Â Server with local HD
- Physical SANEX1PRD: Server with TempDB files stored on a low-end SAN
- Physical SAN1: Server with TempDB files stored on a high-end SAN (around 100000 IOps)
- Physical SAN1 Jumbo: same setup with Jumbo Frame activated on NIC and DB engine
- Physical RAMdrive: with TempDB files stored on a 16 GB soft RAM drive within OS memory
Results were really impressive for the DB engine housing Dynamics AX data. My colleagues from the SharePoint team told me it also boosted a bit overall SharePoint performances but they did not have any baseline comparison to show.If you have some feedback, results, links, whatever I am interested.Indeed before setting this to all our SQL Server 2012 instances I y rather collect some *real world* feedback.

does anyone know if tempdb can be physically moved to a different partition on a disk drive on SQL Server 7.0? Since it can't be backed up I'm hesitant to use the sp_detach/sp_attach procedure because I don't want to crash it. If nothing else is available, I can attempt moving it this way at the end of the day and then just reboot to get tempdb back up again if the server fails, but I'd really appreciate a suggestion from someone who has more know-how than I do about system table operations. Thanks again

I have to move my sql server to new SAN. Tempdb is on old san. If I move the tempdb to c: like below and reboot then move the server, and then after move to new server, start it up, and move again, would that be correct process
i was going to use below to move tempdb to c from SAN
use master
go
Alter database tempdb modify file (name = tempdev, filename = 'c: empdbloc empdb.mdf')
go
Alter database tempdb modify file (name = templog, filename = 'c: empdbloc emplog.ldf')
Go

I have question about tempdb needs to be configured 100GB 64kb block size.its fresh installation.
how to allocate the file sizes.still im not sure how many log files needs to be created with 100GB equals to 64KB block size.
what is 64KB block size and how to divide the logfiles 64KB into the 100gb or 50GB?
what is 64 KB cluster has 128 sectors?
tempdb drives should be formatted with a 64K allocation? how many files needs to created for good performance with 50GB or 100GB? ot 1TB

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.

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,

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

Hello,I'm trying to create a simple back up in the SQL Maintenance Plan that willmake a single back up copy of all database every night at 10 pm. I'd likethe previous nights file to be overwritten, so there will be only a singleback up file for each database (tape back up runs every night, so each daysback up will be saved on tape).Every night the maintenance plan makes a back up of all the databases to anew file with a datetime stamp, meaning the previous nights file stillexists. Even when I check "Remove files older than 22 hours" the previousnights file still exists. Is there any way to create a back up file withoutthe date time stamp so it overwrites the previous nights file?Thanks!Rick

New to Database Mirroring and I have a question about the Principal database server. I have a Database Mirroring setup configured for High-safety with automatic fail over mode using a witness.
When a fail over occurs because of a lost of communication between the principal and mirror, the mirror server takes on the roll of Principal. When communication is returned to the Principal server, at some point does the database that was the previous Principal database automatically go back to being the Principal server?

Hi everyone, I have a small dilema here. I am running SSRS 2000, and I have a report that is grouped by Part Number. I have =Fields!Formula.Value < .1 so I can view only what is greater than .1 Well, my problem is that when I put it under the group Visibility properties, it does not pull all the data. and if i put it under detail Visibility. It does show me everything but any Part Number that is less than .1 shows just the part number but no detail. How can I make my report show all my data but without leaving data out????
Thanks ahead of time,

Has anyone seen the SQL Server error:
"tempdb is skipped. You cannot run a query that requires tempdb"?
We're running a .Net web application with a SQL Server 2000 backend, and we get the error intermittently. Restarting the SQL Server service seems to fix it, as it causes tempdb to be rebuilt, but this isn't a long term solution. Any direction or hints would be greatly appreciated. Thanks!

I have a stored procedure that takes various parameters and performs simple selects using these. A quick summary of the db structure this is working on would be :
lookup_table1
table1_id
description
lookup_table2
table2_id
description
This stored procedure attempts to select the given description from the given table and return the id, if the id isnt present it then inserts the new value and returns the new id.
Now I have this working, ish, but the problem that I have is that in the case of a new insert the procedure returns two datasets, an empty one (as the initial select returned no results) and another with the id of the newly inserted value.
This procedure as it stands right now
CREATE PROCEDURE aida_lookup
@lookup_table varchar(255),
@lookup_id_name varchar(255),
@lookup_description_col varchar(255),
@lookup_value varchar(255)
AS
declare @sql nvarchar(2048)
--
-- Check if the given lookup value exists in the give table / column
--
set @sql ='SELECT ' + @lookup_id_name + ' FROM ' + @lookup_table + ' WHERE ' + @lookup_description_col + ' = ''' + @lookup_value + ''''
EXECUTE sp_executesql @sql
if (@@rowcount = 0) goto new_value
if (@@error <> 0) goto on_error
return(1)
--
-- Insert new lookup value into the given table / column
--
new_value:
-- NEED TO CLEAR PREVIOUS NULL SELECT
begin transaction
set @sql = 'INSERT INTO ' + @lookup_table + ' (' + @lookup_description_col + ') VALUES (''' + @lookup_value + '''); SELECT SCOPE_IDENTITY()'
execute sp_executesql @sql
if (@@error <> 0) goto on_error
commit transaction
return(1)
--
-- Error handler
--
on_error:
rollback transaction
return (0)
GO
The problem being is that if the value is inserted as a new value I need to remove the empty dataset so that regardless of how the procedure is run, it will always return the id at position row 0 column 0.
My attempted solution was to declare a @temp var and place the return value of sp_executesql into this, and if it wasnt null then return it, and if it was then proceed to insert, e.g.
declare @temp int
...
SET @temp = EXECUTE sp_executesql @SQL
if (@@temp = null) goto new_value
SELECT @temp
return(1)
Obviously this doesnt work, so I am open to suggestions. To be completly honest I have run out of hair to rip out and I am sure this can probably be done in a much more elegant fashion, so any help will be greatly appreciated

Hi, Gurus, I am running SQL-Server 2000 on SCSIIs with Raid-5. Three disks. I see only one Logical Disk with 3 partitions. Since it's recommended to have Log files seperate to Data files physicially, currently both exist in the D-Drive. How can it be accomplished?
Another question for ur kind suggestion. I have a merge-repl setup. Publisher and distributor at the same machine. One subscriber over the internet. Replication works through VPN rather that FTP. Whenever i apply SNAPSHOT it takes more that 12 hrs to replicate the 2 GB DB. Although VPN is more secured but the tunneling makes the replication rather slow i guess. Will there be a major difference if i open the default port of ftp on the ISA and change the subscriber to get the SNAPSHOT as Anonymous Subsciption. I mean What's better, Security VS Performance. During the SNAPSHOT the Web-users running on the Subscriber wait for the latest data which is very much annoying.
Another question please, I wanna replace the current publisher-DB machine with a new Hardware-Machine. I don't wanna lose Replication and re-running the SNAPSHOT. Is it possible to retain the publication by restoring the Master, Publication and Distributor respectively on the new machine. The new machine will have the same Operating system name and configuration.
Regards!!

I'm generating emails using sp_send_dbmail. Everything works perfectly except for one thing. In the body of the email I need to show a link to a web page (eg http://myweb/login.aspx).
The problem is that the received email shows the "link" as plain text, ie it is not a clickable link. I've tried adding char(13) (and char(10) and both) after the link text but that doesn't help.
Is there a way to make the link text a real link when received by Outlook? (All recipients will be using Outlook if that helps).
Thanks,
John

I have been requested to add the sum of an interger field to the table header. I have the sum in the footer (which is very easy to do), but I cannot get the sum to appear in the table header.
I then set-up the stored procedure to run the sum, and place it into a dummy field. I still cannot add this field to the table header. Instead of printing the data for the dummy field (the correct total), it instead prints the actual field name on the report.
Is there anyway to place a sum in a table header on a SQL Server Report?
Let me know.
Thank you,
T.J.

Hi,
After exporting the report the column headers in the rreport should not scroll, it has to fix with report headers. If i move the column headers to report header the columns are merging in excel, some columns are hiding.
For ex: I have 10 columns, it has to take from A to K but it is taking A to P. one column is occupying two columns. how to avoid this merging and how to place the column headers in the report header.
Thanks

I do understand the theory behind the steps I just do not know how to accomplish them!If you know of a well-documented tutorial, please point me in the right direction.Regards.
