DB2 (HADR) and time synchronization service

db2girl · #1 (**permalink**) 06-15-10, 16:49

NTP can be used to keep HADR servers in sync. Are there any other clock synchronization services that can be used with DB2 (HADR)? v9.7 / Linux.

Thanks

I doubt there are any. NTP is the standard (the only standard, as far as I know).

What's the problem with NTP?

In the worst case you can schedule something like

Code:

ssh otherhostname "date -s$(date)"

, which should set the date on otherhostname to the same value as on the one where this is run. (It's paper code, so you may need to tweak syntax a bit.)

Thx. Just wanted to know if there is anything else available in case there is some issue with NTP and HADR...
