Autoshrink And Msdb Question
Jul 21, 2004
I have a test database and I detach and reattch this database during my testing on my test system. This database is originally from my production system. I have a couple questions that came up during my testing:
1. When you detach/attach a database from a different server with the same setup, does it gather it database setup information from the model database on the current server?
2. When you switch the autoshrink database option from enable to disable, do you have to restart the server?
3. How to you change the default make of the model database?
Thanks in advance for any help.

Hello,
Ran the Andrew Zanevsky script to shrink the Tran log, this works great, but say the log gets shrinked to 30MB, I then expand it to 40MB, then sometime within a 24 hour period it magically gets reset to 30MB. The database is a standalone DB, and is on SQL7 SP1 the script I ran can be found @ http://www.pinnaclepublishing.com/sq/SQMag.nsf/WebIndexByIssue/F36C151BD80FAD8F852568D0007799BE?open.
Can anyone please give some insight into this or maybe a flag that got reset somewhere?
Thanks in advance
Pat

Howdy folks!
I've got a database that needs to run 24/7. I'm looking into maintanence options and wanted to run the following by y'all:
Ok, I've read the MSDN "Maintaining databases" article and noticed the following statement about autoshrinking: "This technique uses almost no processor time and memory". I also searched these forums and found that many users say autoshrinking heavily lags down sql transfers. So who's right? And if it does lag transfers, by how much?
Another question I have about autoshrink is fragmentation. It would seem to me that over time solely depending on autoshrink would cripple a server in terms of fragmentation; is this the case?
Also, does autoshrink (or manual shrinking or compacting) update the statistics?
Final question!!! I'm programming in native c++, is there a way for me to run commands such as "DBCC SHRINKDATABASE" in native OLE DB code?
Thanks!

Hi,
I had a DTS task running which was doing an insert (over 17.5 million rows) in a database for which the auto shrink option was enabled.
After a few hours I noticed that the insert was blocking the autoshrink.
Since I didn't want to kill my insert, I tried to kill the autoshrink from the query analyzer, but when trying to do so I got the message that only user processes can be killed.
Does anyone have similar experiences? Should you consider enabling the autoshrink option or is this just trouble?

Details: MSDE 1.0 / SP4 - Windows 2000 Pro
I have a database that has Truncate on Checkpoint set for the Log file. The Log file is set to AutoGrow. Is it necessary to to run dbcc shrinkdb (or the like) to get Log file to contract? Is there any harm in not contracting the Log file? I'm looking for best efficiency and least-likely-to-fail path as DB sits 'really remote' and there is little opportunity for observation.
Does anyone have any recommendations on re-indexing? I have one table that bears the most growth. It has a clustered index. What would be a suitable data point to watch? I run a SP to save DBCC SHOWCONTIG info along with the duration of a test query, but haven't seen a clear breakover point.
TIA -RC

Does anyone have any benchmarks for the amount of overhead caused by autoshrink of the log and having autostats enabled? We have a customer that insists that turning off these options was necessary to eliminate a performance problem they were having (Query timeouts), but we are not convinced that these two options would have generated enough overhead to have been the root cause (they also rebuilt all their indexes and made some other unspecified changes that more likely solved the problem).
We are hestitant to have them continue with these options disabled because then we need to rely on them to keep the log file shrunk and the statistics updated and because of the data changes during the day, would prefer to have stats updated automatically rather than on a fixed schedule that may not be as appropriate.
Anyway, if anyone has any feedback on overhead generated and potential performance implications of having either of these options enabled, it would be greatly appreciated.
Thanks,
Ray Rankins

Hello All,I have been encountering trouble with a SQL Server 2000 Transactionlog file, mainly with the constant growth and lack of the autoshrinkoption. Here are the details:1.)OS is Windows 2000 server sp32.)SQL Server 2000 (Build 2195) sp33.)Database Recovery Mode is set to Full4.)Maintenance Plan for "Transaction Log Backup" is set to removefiles older then 1hr.5.)The "AutoShrink" option is on for the DB properties.Also as part of the Maintenance plan the database in question isbacked up nightly. The problem is that the transaction log file hasgrown so much that it was consuming all of the free space on the harddrive so I then restricted the file growth. When all of the drivespace was consumed or the "database log file is full" message wasencountered I would run the following Query scripts to shrink the filemanually:First – Backup Log <database name> With Truncate_OnlySecond – DBCC Shrinkfile (<database name>_log, 200)Which brings the transaction log file down to 200mbs. I need toautomate this so that I don't have to keep babysitting this databaseor manually shrinking the log file.

I know that msdb is used to manage the job schedulers in sql server 7.0 ( job agent ). Does this (msdb) like other databases, where I can control its size, shrink it or expand it.
IF am backing up the msdb, and I errased all jobs scheduled in sql agen. Can I restore all the deleted Jobs by restoring the msdb.

My MSDB is too big [about 14 GB]. When I closely looked all tables, here is what I found -
Top 3 biggest tables are -
sysmaintplan_logdetail - rows- 124923 - data - 13375456 KB
DTA_Tuninglog - 181658 rows - data - 163248 KB
sysmail_mailitems - records - 14227 data - 126208 KB
I am not a DBA, so if any one can explain in simple terms how I can cleanup this maintenance plan log detail without increasing the size of tempdb? How can I stop this database growing in the future?
I have only a gig of space left on that drive.
Thanks in advance

I have a problem with my MDSB database. After my nightly reboot, I received an error in my Lof File stating: Error 9001: Cannot file log device for msdb database. I looked and saw the msdblog.ldf, so I am alittle confused. I ran a dbcc checkdb, dbcc newalloc and dbcc updateusage on msdb, but I did not get any errors. I added an additional log file to try and fix it, but nothing has fixed it. I am perplexed because all my scheduled backups are failing.
Any additional advice would be helpful.
Thank you,

I want to move the physical location of the msdb database on a SQL server. However I cannot drop the database with the drop database statement, even setting it to dbo use only and single user mode. I get an error message saying the database is in use. Obviously I do not want to reinstall the server. The reason I want to move it is because it is located in the default dir on the C: drive which is running out of space.
Any ideas.....

Problem with Msdb
error 1105 can not allocate space in sysbackupdetail.
msdb has 1.0MB of database space available and 1.97MB of log space.
I intended to expand the database but must first expand the device. the available space for the device is -703. So I can not adjust and expand. Any ideas. My hourly dumps appear to be functioning if you view them ny expanding the device but tasks show them as failing.

Hi !
when i am trying to restore MSDB database from a disk backup it is giving an error saying
"Database in use.System administrator must have exclusive use of the databse to run the restore operation".
But i am not using msdb anywhere.when i see the processes under current activities i see an application named sqlagent-alert engine using the database.even after killing this process it reppaears and stops the restore operation.
so i stopped sql server agent and did the restore operation.It worked.
so is it necessary to stop sql server agent while restoring msdb?may i know the logical reason for it?

How would you set up a task run by user without sacrificing the alias permission on msdb (SQL 6.5)?
Situation:
I have set up a task for runing replication by a user with the alias permission on msdb in order for the user to run the task. And I do not want to grant the alias permission to the user for the security reason. But if I set it up by granting only the sp_runtask permission to the user on msdb I always got the message like "You cannot perform this action on a task you do not own."
Please share your workaround. Thank you ahead of time

The sysbackupdetail table in the MSDB database at our SQL6.5 installation has grown to over
50,000 rows, since we back up 25 databases every day. I've enlarged MSDB once because
of a space problem, and I'm wondering whether I can just delete the older entries in this table
to prune it, without dire consequences. MSDB has other history tables, and I'd like to handle
them all the same way.
If I mess with these tables, will the sky fall on me?

Hi,
I am trying to build a test environment for our production server. I backedup and restored all my databases. I had to copy the jobs too, so I backedup and restored msdb database. When I try to change any of the jobs, I get the following message.
"Error 14274: Cannot add, update, or delete a job (or its steps or schedules) that originated from an MSX server."
I have no clue what this message is about. Can someone please provide me with some clues about how I can modify my jobs and get my test environment to work.
Thanks,
Rob

After implementing a recommendation to perform dbcc checkalloc before nightly backup, I began getting the error below on msdb. Books Online suggests restoring from a known clean backup. We have only been using SQL Server for a few weeks and it seems that all our backups of msdb have the same problem. Is there any way of correcting this problem?
Msg 2521, Level 16, State 1

to move all the jobs and dts packages from another server which is running
multiple instances of sql server. I backed up and restored the msdb database
to the new server and now I can't edit any jobs. I get this error?

I'm running Win2000/SQL2000 on a Compaq CL380 Cluster Server. After a powerdown to do a physical move, the MSDB is now marked SUSPECT. I have tried the stored procedure SP_RESETSTATUS, a DBCC consistency check, and also have restored the database from backup. The database still shows MSDB is suspect. What can I do? We can't get a good backup as long as it is still this way as it depends on the SQL Agent.
