Solaris 9 4/03 版次注意事項

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

Solaris 9 版本不支援 priority_pagingcachefree 可調參數。這些參數已由增強的檔案系統快取架構所取代,可執行類似於優先分頁的分頁策略,但始終都處於啟用狀態。在 /etc/system 檔案中嘗試設定這些參數將會產生開機階段警告,如下所示:


抱歉,變數「priority_paging」未在「kernel」中定義
抱歉,變數「cachefree」 未在「kernel」中定義

如果您升級至 Solaris 9 版本,或使用 pkgadd 來處理 SUNWcsr 套裝軟體,並且 /etc/system 檔案包含 priority_pagingcachefree 參數,則會發生以下情形:

  1. 如果您在 /etc/system 檔案中設定 priority_pagingcachefree 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,並且在設定 priority_pagingcachefree 的任何一行之前的位置。 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
