DBA Kevlar

Tips, tricks, (and maybe a few rants) so more DBAs become bulletproof!

Scripts

This is a collection of scripts that I’ve found useful over the years.  Please feel free to utilize any you would like and hopefully they will serve others as well as they have served me.  I have tried to ensure that if an author of the script is known, it is shown in the script.  You will see some that I’ve had for so long, I have no idea where the original source is from or even if it is in the original form, (vs. me having personalized it as I’ve gone along…) I have a tendency to utilize very generic, simple scripts and edit them to the needs of the specific situation. If you have a request for one of the ones here, just let me know!

AWR Streamlined Repository

I’ve been asked a couple times for this, so searched it out and added it here.  This is the DDL for a repository table to store data remotely/locally for the high level hourly data requests based off some wonderful queries from Karl Arao that we would email back and forth, discussing how we could make it into something *more*… :)

AWR DDL by DB_ID

Hourly Report of AWR Data, identified by DB_ID, can then be used to report or fill into DDL created in table above.
