Unable To Truncate Everything From Tempdb Online Log
Mar 27, 2006
Hey guys,
I'm having difficulty completely truncating my tempdb online log. It sits at 25%, and remains allocated even after I've truncated the log with backup log tempdb with truncate_only. Now, I would assume this to be normal if there is a spid who hasn't commited or rolled back a transaction, or if checkpoint hasn't run. However, running DBCC opentran('tempdb') shows me that there are no open transactions at that time, and checkpoint appears to be running fine.
Can anyone give me any hints on which way I should point with my investigation.
A customer on SQL7 has a 40GB tempdb (which is usually 2-5GB) which has filled the drive. ShrinkDb/ShrinkFile do nothing as the db has only 2GB of free space. How can I truncate the data or blitz tempdb and create a new (2-5GB) one (Stopping the server, deleteing the .mdf, starting the server creates a new tempdb with the same size as the old one!)
Within SQL Ent Manager - I am unable to truncate the tran log using the shrink file option window (although I can shrink the database file) - nor can can I truncate the log using command line sql in a query analzer window (dump tran < > with truncate only)....
I am using SQL2005 SP1 and I have a 4Gb Tempdb (datafile) with virtually nothing in it.
I am unable to release the free space to the operating system. I have used dbcc shrinkfile...truncateonly but this has had no effect.
There is no error message and there are no open transactions, I have attempted to drop the data file by transferring to a new file but I can't because it the primary file...
SELECT session_id, SUM(internal_objects_alloc_page_count) AS task_internal_objects_alloc_page_count, SUM(internal_objects_dealloc_page_count) AS task_internal_objects_dealloc_page_count FROM sys.dm_db_task_space_usage where internal_objects_alloc_page_count >10 and session_id> 50 GROUP BY session_id;
[Code] ....
Database MDF is 27806 MB and I tried to shrink but unable to shrink. It is production server.I do not want Restart sql server.There is no open transaction.
We have SQL cluster installed on top of windows cluster on VM environment. Node1 and Node2 under Windows Failover Cluster. SQL instance is currently on node2 the instance is up and running, but SQL Cluster service remains online pending and it restarts the instance on every 5 minutes.
SQL Browser service are running successfully.TCP/IP ports are enabled and configured.If we start the SQL server agent it is on for seconds and stopped immediately  .Cluster Service is attempt to connect to the SQL service every few minutes (setting in SQL cluster resource) for the IsAlive check, if this fails then the SQL resource is restarted even if the instance was online. Hope this is what happening exactly.

With a database size of almost 2 GB, I run the 'truncate table eventlog command' which completes successfully, but the database size only decreases by about 10 MB so stays too large - indeed the number of rows in the eventlog table is minimal, but the otehr tables in this database don't show such an amount of tables large enough to cause the size issue either. What could be the reason and how can I reduce it (possibly truncating another table but then which one, how could I determine which is too large and needs truncating?).
"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! - Mike
Please forgive the elementary nature of my question, but could someone please explain the differences between these two database backup types:
1. Log backup 2. Log backup no truncate
From what I understand and have read, the "no truncate" backup method keeps the entire transaction log indefinitely. Using the truncation method, the transaction log is either 1) compressed or 2) cleaned up so that any completed transactions are removed from the log. Which one of these is true?
And, for the big question: is it better to run a backup of the transaction log with truncation or not? Our current backup scheme is similar to the following:
Full backup every 24 hours transaction log backup every hour with no truncation
Should we insert a truncation backup somewhere in here? What is the danger of removing (or compressing) parts of the transaction log? Will this affect the restore process?
I have made a small mistake while restoring the DB I selected the 3rd option in the em
Leave the DB read-only and able to restore additional transactional logs
I have just realized that all I have is a complete back up to restore & no transaction logss...
I see the Db in a Read-only state & when I try to get it online It says Error 5063 : Db is a warm standby. A warm standby db is read-only Alter DB statement failed. sp_dboption command failed
I know MMORPGs take tons of special servers, but what about a simple 2D minorly-multiplayer online game, say with 3-5 players- could that be run through an SQL database or is it still too slow?
Can someone share with me their experience or thougts on whether it is better to : 1) backup db to the disk first, then to the tape OR 2) use online backup which backup the database on realtime basis to the tape.
Can anyone tell me how I would go about making my SQL server accessable from the Internet, or know of any good tutorials to get me started, I haven't had much luck looking on google.
I need to access an SQL database from one server on another server for a web application.
I have started to learn SQL, I need to practise those commands through online sql interpreter. Is there any web page available to do so? or where can i down load it for free?
How do you use BOL? I've heard time again that there is much info in BOL but when i look at it it seems too brief and not detailed. I find it hard to find what i'm looking for anyway. How do you use it?
Dear Friends,I don't know anybody has asked this question before or not.But I needa support urgently.How to take online backup in MS Sql server 2000.ThanksArijit Chatterjee
alter database bdj add file (name ='bdjfg1', filename='d:db djfg1.ndf' ) to filegroup bdjfg;
alter database bdj modify file (name='bdjfg1', OFFLINE);
alter database bdj modify file (name ='bdjfg1', filename='d:db ewdestdjfg1.ndf' ); --Msg 5056, Level 16, State 4, Line 1 --Cannot add, remove, or modify a file in filegroup 'bdjfg' because the filegroup is offline.
alter database bdj modify filegroup bdjfg READWRITE; --Msg 5056, Level 16, State 3, Line 1 --Cannot add, remove, or modify a file in filegroup 'bdjfg' because the filegroup is offline.
Yes, yes and should have read the cautions section saying:
"Use this option only when the file is corrupted and can be restored. A file set to OFFLINE can only be set online by restoring the file from backup. For more information about restoring a single file, see RESTORE (Transact-SQL)."
But I have not an backup of the datafile, but I have the datafile itself!
What can I do to get it online again, the old location could be fine, but it would be better on an new location (thats is the reason for all the trouble, the original drive has not much space left, so I wanted to move the datafile)
Hi all; I am trying to login to an online sql database from enterprise manager; First of all is this possible and second of all, how do I go about doing it from enterprise manager (by the way I am using MS SQL 2000) THanks for any assistance
I hope i'm in the right forum. Is there a way to create a DB diagram schema via ASP/HTML and publish it on-line - keeping it up-to-date? I want to at least output a diagram schema to HTML format? Any ideas. TIA!
We have just release a free Online SQL Formatter which can beautify different sql dialects for you on the fly, and translate to other languages such as C#, Java,Delphi with many format options.

Can anyone guide me to a place where I can download some Tutorials / Books (Not that new) covering Microsoft SQL 2000 essentials ? I tried to find here, but artices are too advanced for me.. I need something that covers the Basic and that could be used as a small reference/guide while I am learing...
Does anyone know which SP to use to get the list of available servers? I want to call it from a VB app via ADO to provide the user with a choice of servers available.
I've just started with a company that had a web developer in to set up their site. She set it up with Coldfusion and MS SQL Server, uploaded the whole thing to their provider, then disappeared. Then the whole thing got dumped in my lap, and I'm pretty new to both SQL Server and Coldfusion.
My first question is, how can I access the SQL Server database online? It's somewhere on the web host's site, and I have the name of it and the password, but I have no clue how I'm supposed to get a look at the thing. Is there a file I should be able to find? Can anyone provide a clue?
I am sure that most of you will have seen this but for those of you who haven’t, its basically a dialog box where you dump you T-SQL and then tell it which system your using (ie. MS SQL). When you press the format button, it returns an almost perfectly formatted version. The link is:
Anyone using the ONLINE=ON option on large DB's? We have a db of 5 GB and we are doing some load testing for SQL 2005. We are modifying the Index scripts for the upgrade. We will run a load with the ONLINE=ON option but just wanted to find out if anyone already is doing it on a similar scale db and has seen any issues? Also, we have auto-update stats off at the DB level. Does setting the ONLINE=ON require turning this auto-update stats to ON too? I didnt see anything to that effect in BOL, so was wondering.
Thanks for any feedback.
