hi
BACKGROUND
I have a production environment for a service running oracle on a sun
server and this has a backup server in standby mode using oracle 10g
dataguad. This standby server can also be used for read only reporting
at the same time.
MOVING FORWARD
I have a development, test and training environment consisting of
separate database instances on a separate machine.
I'm trying to work out the pro's and con's of having the production /
standby environment in an active/active set up and moving the
dev/test/training database onto the standby server as well. At failover
time the dev/test/training environment would failover onto the old
primary.
PROS
- cost - less servers to manage and buy / have support for
- more manageable - one server to manage
CONS
- possibility of developers accidentally connecting to the production
environment
- cant tune the production environment 100% for the live app as server
will have to be tuned for the other dev/test/training instances as well
e.g. with memory allocation etc.
- at failover time old primary server may be unavailable for
dev/test/training to failover onto - production performance could be
affected with the dev/test/training use. developers experience
performance probs, cant do what they want to then ask why
dev/test/training doesn't have its own environment/server.
Question
Does anyone have any experience of this and can they recommend some
pro's and con's?
Many thanks.
Thiko!
