i don't know about all of those, but you should put the ptf's on your HA
system yourself as part of standard system maintenance. not do it when you
fail over.

The HA process does NOT keep both boxes identical. Think about it. Would

they have the same
- IP addresses
- Same system name
- same WRKRDBDIRE
- same network attributes
- same routing

They also will not have the same vendor keys. These are often tied into
serial number, processor and what not. Many times a vendor will have a
technote that says to omit data area x in library y from your HA software.

Do you really expect a change to WRKRDBDIRE on one system to be propagated

over to the other system? No. User profiles, user libraries and so on,
yes. I don't even expect a HA solution to keep DSPPTF in sync. How would

you expect it to?
