Can you not make the second DB a slave of the main one, it'll be permanently up to date that way and it doesn't require any copying. For integrity to be maintained during the copy you'd have to stop the database otherwise, or you could have unpleasant conditions occuring where some database writing occurs while you're copying it. p > D > > > > --------------------------------------------------------------------- > To start a new topic, e-mail: users@tomcat.apache.org > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
