Interesting, we were wondering if you could run ontape on the secondary<SNIP>
to back up the database but I have been so busy I haven't been able to
investigate or test it. (I just realized it would probably only take a
minute to check the c.d.i archives, but then I couldn't implement it
for 6 months anyway.)
Yes you can run ontape on the secondary to get a consistent archive of the
servers. The operation would not block or otherwise affect concurrent
updates from the primary except as any resource usage on the machine and
server would. The archive would be restorable onto either host.
Really? How can this be? The replicate, sitting there as it is waiting
eitther for further transactions or fast recovery, may be physically
consistent but how can it be logically consistent?
If I try it it doesn't work, just as I'd expect:
$ onstat -g dri
IBM Informix Dynamic Server Version 10.00.FC3 -- Read-Only (Sec) -- Up

$ ontape -s
Server is in an incompatible state or user authentication failed.
Program over.
