Home -> Community -> Usenet -> c.d.o.server -> Re: EMC SRDF or Advanced Replication????
Pete,
Thanks for the response. A follow-up question for you: From an
administration standpoint, it
seems like using updateable snapshots or replication could turn into just an
amazing nightmare.
In theory, I would like to believe all the *claims* regarding advanced
replication or snapshots,
however how easy/difficult is it in real-life to coordinate all the areas of
the snapshot/replication
methodology? For example, if I have to cut over to the failover database at
3:30am, and don't have
access from my telnet session at home to the GUI replication manager, and
have to run scripts that
access the replication API, is this fairly easy to do, or very complex?
Thanks in advance,
Steve
