Hi Tanel-
I've been doing 11.5 cloning for several years and think I've found most (but I'm sure
not all) of
the database and filesystem changes required.
adpatch is what concerns me the most since it requires a database connection to
function. It can't
connect to the DR database since it will be in a recovery mode. I'm thinking that
setting the
two_task to a service that points back to the production system would work. You bring
up an
interesting question though. c, d, and g drivers are very specific in the functions
they perform.
Now that Oracle is moving to the u driver, I'll need to look into this.
I was looking at rsync as an alternative to the above. rsync would also be used to
transfer the
concurrent reports (/.../common/out) to the DR system (don't know if management want
this yet or
not).
Time for coffee.... not sure if I'm making sence yet.
Thanks,
Ron Thomas

One issue popped into my mind with patching & disaster recovery:
When you're patching your primary system, have applied all c & g and d
drivers (or an u driver) and a disaster occurs, then your secondary site
might remain in inconsistent state e.g. database objects have the new
version, but corresponding $APPL_TOP ones are old, because they're not
rsynced yet.
Or the opposite - when rsync has been done, but you have to do a point in
time recovery to the point before d-patch application in secondary site.
And of course, don't forget to simulate and test the disaster, several
times, if possible. Without warning, if possible ;)
Tanel.
