Dear Selected few:
Enviro:
one H70, 4 GB/4 CPUs, 4.3.3.10, SSA, NO HACMP, running 1 Production Oracle
8i instance.
TSM backup.
one H50, 3 GB/3 CPUs, 4.3.3.10 ("warmspare")
Management Wants:
A non-HACMP hotspare or warmspare environment for our Production Oracle 8i
db.
Management will tolerate 1 hour downtime when switching to "warmspare"
server.
While I know in general about HACMP, I would like to pick your Admin.
brains on this question:
Question 1:
Would a HACMP environment be advisable instead of our home-brew "warmspare"
environment.
The home-brew "warmspare" environment involves many different scripts to be
run to keep the "warmspare" server in-sync with the Production server. It
also necessitates many mechanisms to make it the Production server, and
then many more to make it again the "warmspare" non-Production server.
Wouldn't HACMP be easier for all concerned??
Question 2:
When using HACMP w/Oracle, when HACMP switches, does the "new" Production
server change its hostname, etc.?
Without going in to too much detail, how does HACMP switch the Oracle/AIX
parameters to maintain Production on the new Production server?
It seems to me that we are "reinventing the wheel" with our home-brew
"warmspare" server and would be much better using HACMP instead?
