If you have put transaction processing semantics in your code you will have logical consistency with dbpause. For RFS enabled systems, dbpause forces a checkpoint.

You're never guarenteed that you have a clean consistent copy. -----Original Message----- From: John Jenkins <u2g...@btinternet.com> To: 'U2 Users List' <u2-users@listserver.u2ug.org> Sent: Wed, Aug 8, 2012 6:02 am Subject: Re: [U2] dbpause/dbresume or stopud/startud "dbpause" and "dbresume" allow any background processes (e.g. PHANTOM or WebDE (Redback)) to continue running. You do not have to have a restart procedure. Additionally, as long as your backup methodology is brief - a SAN "snap" or a mirrored drive split - then anyone using Telnet, UniObjects or ODBC not even notice and can continue uninterrupted. Stopping UniData menas terminating those sessions I'd look at what is blocking your dbpause - there is a Tech Tip in the U2 knowledgebase.- search on "dbpause" - you should find SFMA-13082.

The reason for my question is that my server is running unidata 7.2 but 50% of the time cannot resume and stays in dbpause state long after backup?
