Survey: What is everyone doing for availability?
Robert,Availability levels.......
1st line of defense: We maintain old fashioned "bus level mirroring" on our PRD
DB (1200GB/600GB usable) -
2nd line of defense: We are 3tier in PRD & have 2 SB3 app servers; when we have
had 1 SB3 out for any length of time, we've moved the business to run on a
single SB3
3rd line of defense: We perform a SAVWACT every night to 3590-E11 tape drive;
this has the business down for approx 1/2 hr for the process of coming down,
saving IFS, reaching a checkpoint, coming back up
4th line of defense: (implementation date 07/2001) We will be implementing HA
software (vendor yet to be chosen) since we will be rolling out European
locations & the 1/2 hr downtime for SAVWACT is not acceptable. HA box installed
onsite here.
5th line of defense: Finalize Disaster / Recovery Plan (09/2001); There is
much debate over how far to go with this. It is very easy to say that we should
put the HA box at a remote site. That part is easy. The logistics of desktop
pcs & network infrastructure is the issue here.

Hi Everyone,
Please don't complain that this is the same query as the H/A postings
that went on recently!!! It is different!!!
Our management wants us to prepare a number of different
availability/recovery scenarios and the relative expense of each. We are
not seeking just 7/24 solutions, but we are analyzing the whole
continuum of availability from just RAID5 DB with RAID1 journaling, on
up to full blown 7/24 availability. Our management wants us to prepare
a number of different availability/recovery scenarios and the relative
expense of each.
So please drop a line and let us know what you are doing in this regard
and what your opinion of it is.
By the way, a belated thank you to everyone who responded to our inquiry
regarding the different options for our OSS connection. We are going
with frame relay because we require the uptime and bandwith. We were
also concerned about SAP getting on the system at odd hours. Thanks!!!
