Hi Matt,
I think you mentioned that were on Solaris 10? We had what sounds like a
similar problem with our Solaris 10 zones and Oracle 12.1.0.1. In fact, not
only would the database fail to start but we couldn't even kill the background
processes and shutting down the zone would hang. In the end we had to reboot
the entire server which wasn't popular!
Have a look at MOS Note 1981697.1 which states that OSM is not supported on
solaris 5.10 (I didn't see any further details on this).
We applied both patch 19217491 and disabled automatic memory tuning (AMM/ASMM).
The database reverted to ISM and restarted fine and critically didn't hang
the zone. This wasn't a busy system so we weren't too worried about the
performance impact of disabling AMM (static settings worked just fine).
Ideally I'd have applied the patch OR disabled AMM to evaluate things a bit
more scientifically but such was the business fallout of having to reboot a
server with multiple unrelated other zones we had to adopt a belt-and-braces
approach to avoid a re-occurence rather than a selective one.

But in 12c, Oracle prefers using OSM over either ISM or DISM. That appears
to be the cause the of the problems I’m having.
Anybody else install 12c on solaris and have issues with OSM not working as
expected?
