Sun Studio 12 update 1 is not a patch update release of SS12
A quick note on the confusion about whether Sun Studio 12 update 1 is a patch-update release of Sun Studio 12 or not.
This particular naming convention has been a source of some [B]major confusion[/B] for some customers, so let me come out and say it straight:
[B][I] [I]"Sun Studio 12 update 1 is NOT a patch update to Sun Studio 12". [/I] [/I][/B]
They are in fact independent releases (much like Sun Studio 12 and Sun Studio 11 were).
Think of SS12u1 as SS13:
[LIST] [*] Like an independent release, you can install it alongside SS12 in a different partition. [*]Patches made for SS12u1 do NOT apply to SS12 [*]Patches made to SS12 have been rolled into SS12u1 as bugfixes, but from the date of SS12u1 release (June 2009) these two maintenance source trees have diverged [*]If an ISV (Oracle apps are included in this) requests a certain patch level for Sun Studio 12 or for Sun Studio 12 update 1, do not assume you can use Sun Studio 12 update 1 instead. You cannot. [*]If an ISV (or other support document) states that "Sun Studio 12 patch xxxxx-nn or higher" is supported or required, do not assume that Sun Studio 12 update 1 will suffice instead, since as you've seen here, those two dont really have anything in common. [/LIST] This issue gets particularly confusing because Solaris rolls its patches into update releases, so effectively Solaris 10 update 6 (eg) has all the patches created upto a certain cutoff date. Sun Studio does not do this and has never actually produced patch-update releases in the past in this sense.
