Question:
We have a table in production, which is saving quotes and whenever these quotes are not used, corosponding rows get delted. This table is heavily exposed to deletes and updates.
We have a nightly task running update statistics as well as dbcc chekdb,
we often get errors stating that the indexes are corrupted. We beleive it is due to disk fragmentation.
we fix the problem and it happens again.
Can any body advise why it is happening and what can be done about it?
Dear All, i'm planning to drop all the non clustered indexes (as they are not congigured well) on production database, and run the latest script to create fresh non clustered indexes on specific columns.
now my doubts are 1)will the replication affect with dropping and recreating of indexes? 2)query to drop all the non clustered indexes on that database.... can i use the query delete from sysindexes where indid>1 will the query works for me to drop all the non clustered indexes? 3)is it necessary to generate a snapshot again after creating the new indexes? or can i drop and run at subscriber also?
please guide me in this regard

I'm working to improve performance on a database I've inherited, and there are several thousand indexes. I've got a list of ones which should definitely exist within the database, and I'm looking to strip out all the others and start fresh, though this list is still quite large (1000 or so).
Is there a way I can remove all the indexes that are not in my list without too much trouble? I.e. without having to manually go through them all individually. The list is currently in a csv file.
I'm looking to either automate the removal of indexes not in the list, or possibly to generate the Create statements for the indexes on the list and simply remove all indexes and then run these statements.
As an aside, when trying to list all indexes in the database, I've found various scripts to do this, but found they all seem to produce differing results. What is the best script to list all indexes?

We have one database of 5 GB of which when we take the backup and restore in another location, it says "Device Activation Error. The Physical file name e:databaseike_log.ldf may be incorrect". The database has more than one log file. Now when we use another procedure to create new database and stop the sql, then replace the old mdf file and REBUILDLOG. (Ie dbcc rebuildlog(nike,1,0)). It says incorrect DBCC Statment.
SQL Server 6.5. Hi! When I try to create PK, Clustered index on the column in the table I have got error message: 1105 Couldn't not allocate space for object table1...... But it is a big amount of free space in the database. And actually I can create any indexes, exsept clustered with no problem. DBCC CHECKALLOCK for this table shows: extent not ih the segment. Does it mean the table structure is corupted? What Can I do to resolve the problem?
When I am trying to restore the backup it is giving an error message "An internal consistency error occurred. Contact Technical Support for assistance".
Please suggest me on this issue.
Is there any way to restore the backup or recover the backup.
I have a SQL 2000 database whose MDF is approx. 105 GB. Everything has been working fine for months until this past weekend when the database server dropped offline. I restarted the services and SQL server looks to have started up okay. However, trying to access it via Enterprise Manager causes EM to hang. Checking the Windows event log, there are a whole series of messages stating ...
3455 : Analysis of database 'ptportal' (7) is XX% complete (approximately 61 more seconds)
This 'analysis' ran for over 12 hours ... I have never seen this run before, much less this long. Now, there are a new series of messages stating ...
3450 : Recovery of database 'ptportal' (7) is XX% complete (approximately 56526 more seconds) (Phase 2 of 3).
This 'recovery' has been running for 9 hours now. Does anybody have any idea what has happened here or what is going on? My guess is that this database has been corrupted and SQL Server is trying to do a repair? Anybody know how long this usually takes and what the success liklihood would be?
this may well be the wrong place for my post, if so please move it.
I have a variety of boxes with SQL tools installed on them. For some reason last week several of them seem to have gone a bit squif.
Server 1. Enterprise manager fails to run, giving message MMC could not create the snap-in. QA runs fine.
Server 2. Load EM click on a database and try Tools --> QA it comes back with File Not Found. Add isqlw as an external tool and you can run that ok, but still File Not found on the QA tab.
I know its not data corruption, but I hope someone can give me a clue on this!

I was working away as usual, when BIDS crashed. Upon re-starting, my package tasks no longer had any connectors between them! However, if I selected, then clicked on them, the connectors reappeared again. I thought this was a one-time problem.
However, now other packages, upon opening, are missing the task connectors as well. This has never happened before until this morning after BIDS crashed. It seems to be permanently corrupted at this point.
Should I reinstall SSIS? Has anyone else seen this before?

I am backing up SQL 6.5 DB using Backup Exec 7.2 on NT 4.0 server SP4 with SQL server agent. The backup job ends in Failed status and a warning that DBname is corrupt. I then try to run DBCC Checkdb, newalloc, and checkcatalog commands to repair the DB. No further ahead yet. Are there any other commands that I can perform on the DB so that the corruption can be repaired, or verified there indeed is corruption of DB?

Recently, one of our database's mdf and ldf was corrupted. We were able tobring back the database with the capability of importing and querying thedata. However, the data is not the full list. Some of the data are stillmissing because the tables we want still has sone 'chain mis linkage' errorwhen we did a DBCC checkdb/checktable. DBCC couldn't fix those errorseither. We're pretty sure that there are some data still burry under thecorruption. Then we thought of the life LDF file. This file should haverecorded every transaction up to the point of failure. So we trying torecover that file, but there are 2 problems. First is we don't have back upof that file and 2nd, that file is also corrupted. I couldn't backup thecorrupted ldf file at its current state. It's giving me some unrelated errormessage like disk space is out. All I know now is the only hope to recoverthose missing data are in this LDF file. We tried to use this software fromLimingent Log Explorer to recover it. So far no such luck with that. SoI'm asking anyone who has similar experience or problem. Please let me know.I need to know anyway to recover this LDF file, either by using sql server'snative tools or 3rd party tools. Any input is helpfull. thanks in advance.Wei
