solaris and derivatives, what is that unix?

the difference between solaris and after projects?


hello
since few weeks im trying to understand a bit the unix* world, except linux that i know since a while.

i discovered the BSD family, now since a little time i hear about solaris, qualified of "unix" on the wiki, instead of unix-like for lot of OSes

looks like it's (not far) of being abandonned, due to the oracle's acquisition of sun microsystems (java, OO.org etc), but several remains :
-oracle solaris, original
-illumos
-openindiana

i have saw on youtube that openindiana have very few application in it's default install (firefox, thun..) plus is a bit slower than common OS..

i'd like to know, in addition of database management (oracle?), in which usages, in the 2000s (or even after), does solaris-like systems, where used to?

thank you

Sun Microsystems developed several enhancements to Solaris:
In the early days (where it was named SunOS): NFS, NIS, automounter.
These were licenced by other Unix vendors. And so became de-facto standards.
Linux re-engineered them.
Later enhancements were
/proc and ptools (pgrep, pkill, ...),
RBAC (roll based access control, could replace the static UID 0 superuser model),
doors (a simple IPC mechanism that Solaris used because its socket implementation was slow),
SMF (service management facility, replaced the SysV init files),
configuration registry (a DB replaced /etc files),
ZFS (replaced the UFS-based file system and volume manager),
live upgrade (patches on a new file system root).

Despite the changes Solaris always sticked to the Unix principle: do one thing and do it well. For example the SMF cares about services: startup, shutdown, supervision. Its development is complete, it does not evolve /creep into other parts of the OS.
In Linux there is another philosophy: a piece of software is never complete. If development stops then, even if it works well, it must be timely replaced; often a security risk is anticipated.

Solaris 11 is a commercial OS still regularly updated. Last SRU (Support Repository Update) is #67

It's commercial support is scheduled until 2031 (Extended Support until 2034) so it's not (yet) abandoned.

Should you want to test it, you might download Solaris 11.4 CBE here.

That is not that simple, there was a sunfreeware.com which offered a lot of linux tool ported to sun. If I remember well.
