Subject: Logging to MySql / relational databases
From: "Harley N" <[email protected]>

I have an Epics database used for displaying a fairly large numeric dataset with a refresh time of roughly 30 seconds.  I'd like to create a time based log in a relational database, preferably MySql.  The old version of this system is using VSystem and VLog, which works but has bad performance when doing queries.

Are there any premade utilities for logging changes of an Epics dataset to MySql?  Or could someone point me in the right direction for where to find tools for logging to a relational database?

Thanks,

Harley.
