Paging All SQL Monkeys!

[MarillionFan]

Read TPD about the Mickey Mouse project Eek and I are on at the moment, then re-read that statement, I'm a Release Manager and Eek is a code monkey, he is playing BA and I am playing DBA

Playing being the operative word.

Sorry, you've completely lost me there

If you are talking about one SQL Instance (and it's DR solution) it really can be worth getting a proper production DBA in to give the system a full healthcheck, set up maintenance, report on deviations from best practices, lock down the security etc. It can be done in a couple of days and save a lot of grief. Development DBAs can not be relied on for this, it isn't what they do. Now where would you find an experienced production DBA

If we could do the indexes without taking the server down we could justify spending weeks on it.

Yes, Ola's solution is what we use at my current site as a full ongoing maintenance solution, it even builds the jobs for you. Bit OTP for the OP though.

This one looks good.

Anyone got a quick and dirty script they rely on to rebuild all the indexes in a database for SQL 2008 R2?

There is a few in google but would prefer one that comes for someone here

If you don't trust random scripts on Google, ask on StackOverflow and rely on the peer view system to spot obvious problems.

You have to be careful here and I refer you to

Not quite:

Add question to stackoverflow

Get mate to write your solution down as the solution to the problem.

Then if no one else comments you have both fixed the problem and set up your solution as best practice...

Ironically at previous clientco we discovered that a previous contractor had done exactly that.

As at the moment if I snuck a few drop table ..... commands in the script Simon would probably happily run it.

If you really want to rebuild them all, use a maintenance plan, for something doing only those that need it and switching between reorg/rebuild with logic for which edition and online or not use Michelle Uffords (SQLFool) script Index Defrag Script, v4.1 SQL Fool

From the people that actually post in technical....

You are a braver man than me....
