The following sections describe new or changed parameters in the Solaris 9 releases.
This parameter is new in the Solaris 9 12/02 release. For information, see
Removal of sun4d Support
The sun4d platform is not supported in the Solaris 9 release. The
following parameters were modified to reflect the removal of sun4d support:
Unsupported or Obsolete Parameters
priority_paging and cachefree are Not Supported
The priority_paging and cachefree tunable parameters are not supported in the Solaris 9
release. They have been replaced with an enhanced file system caching architecture that
implements paging policies similar to priority paging, but are always enabled. Attempts to
set these parameters in the /etc/system file result in boot-time warnings such as:
sorry, variable 'priority_paging' is not defined in the 'kernel'
sorry, variable 'cachefree' is not defined in the 'kernel'
The SUNWcsr packages that contain the /etc/system file have been modified so
that the inclusion of the priority_paging or cachefree tunable parameters are prohibited. If
you upgrade to the Solaris 9 release or add the SUNWcsr packages and
your /etc/system file includes the priority_paging or cachefree parameters, the following occurs:
This message is displayed if the priority_paging or cachefree parameters are set in the /etc/system file:
/etc/system has been modified since it contains references to priority
paging tunables. Please review the changed file.
Comments are inserted in the /etc/system file before any line that sets priority_paging or cachefree. For example, if priority_paging is set to 1, the following lines are inserted before the line with the priority_paging value:
*NOTE: As of Solaris 9, priority paging is unnecessary and has been removed.
* Since references to priority paging-related tunables will now result in
* boot-time warnings, the assignment below has been commented out. For more
* details,see the Solaris 9 Release Notes,or the "Solaris Tunable Parameters
* Reference Manual".
