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. |

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. |
