Cross posting from my Solaris 11 Lifecycle blog, https://blogs.oracle.com/Solaris11Life/entry/orachk_health_checks_for_the as this is applicable to Solaris 10 too:
My colleagues, Susan Miller and Erwann Chénedé, have been
working with the nice people behind the ORAchk tool (formerly RACcheck)
to add Solaris health checks to the tool.
ORAchk 2.2.4, containing the initial 8 Solaris health checks, is now available:
ORAchk includes EXAchks
functionality and replaces the popular RACcheck tool, extending the
coverage based on prioritization of top issues reported by users, to
proactively scan for known problems within:
ORAchk will expand in the future with more high impact
checks in existing and additional product areas. If you have particular
checks or product areas you would like to see covered, please post
suggestions in the ORAchk community thread accessed from the support tab
on the below document.
