Hi all:

I have a log database used in manufacturing tools that creates up to 100,000 - 200,000 entries daily. I need to clean out records that are more than 8 days old on a daily basis and I am looking for some ideas on how to do this. The constraints are that this tool must continue to run during the clean up process. The options I've tried suck up alot of CPU time and interfere in the operation of the tool (timing is a very big issue in the type of testing this tool does) . I thought about spawing a thread with its own connection once a day to do this cleanup but am unsure of how safe this is. I have SP's in the database for doing the deletions. I am running Firebird v. 1.0.0.679 and am using Delphi 6 client/server.

Thanks for any suggestions.
