The priority_paging and cachefree tunable parameters are not supported in the Solaris 9 release. These parameters have been replaced with an enhanced file-system caching architecture that implements paging policies that are similar to priority paging, but always enabled. Attempts to set these parameters in the /etc/system file result in boot-time warnings such as the following:
sorry, variable 'priority_paging' is not defined in the 'kernel' sorry, variable 'cachefree' is not defined in the 'kernel' |
If you upgrade to the Solaris 9 release or pkgadd the SUNWcsr packages, and your /etc/system file includes the priority_paging or cachefree parameters, the following occurs:
The following message is displayed if the priority_paging or cachefree parameters are set in the /etc/system file:
NOTE: /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, this line is replaced with the following lines:
* 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". * set priority_paging=1 |
