優先分頁和相關的可調核心程式 (priority_paging/cachefree)

Solaris 9 發行版本中並不支援 priority_paging 和 cachefree 可調參數。 這些參數將取代成已增強的檔案系統快取架構，它可執行類似於優先分頁的分頁策略，但每次都會啟用。 在 /etc/system 檔案中嘗試設定這些參數將會產生開機階段的警告，如下所示：

sorry, variable 'priority_paging' is not defined in the 'kernel'
sorry, variable 'cachefree' is not defined in the 'kernel'

若您升級至 Solaris 9 發行版本，或 pkgadd 等 SUNWcsr 套裝軟體，且 /etc/system 檔案包含了 priority_paging 或 cachefree 參數，則會產生下列情況：

1. 如果您在 /etc/system 檔案中設定 priority_paging 或cachefree 參數，則會顯示下列訊息：

   NOTE: /etc/system has been modified since it contains references to priority paging tunables. Please review the changed file.

2. 註釋會插入在 /etc/system 檔案中，且會是在任何一行設定 priority_paging 或 cachefree 之前的位置。 例如，若您將 priority_paging 設為 1，這一行就會取代成下列幾行文字：

   * 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
