訂​閱​管​理​程​式​（Subscription Manager）

Red Hat Enterprise Linux 5.11 中​的​「​訂​閱​管​理​程​式​」​會​在​使​用​附​加​檔​案​之​後​立​即​產​生​ redhat.repo 檔​案​，而​不​會​等​待​ yum 工​具​程​式​。​
「​訂​閱​類​型​」​欄​位​已​經​納​入​「​訂​閱​管​理​員​」​程​式​中​。​使​用​者​可​以​在​命​令​列​與​圖​形​化​介​面​中​檢​視​欄​位​，得​知​目​前​使​用​的​是​何​種​訂​閱​類​型​，用​以​決​定​訂​閱​行​為​之​屬​性​。​

  • 現​在​ subscription-manager list --available 指​令​的​輸​出​資​訊​包​括​庫​存​數​量​的​資​訊​（SKU，stock-keeping unit）。​

章 5. 虛​擬​化​

當​ RHEL 5.11 執​行​ virt-who 代​理​程​式​時​，virt-who 可​以​與​ VMWare ESXi 溝​通​，並​為​ Red Hat 訂​閱​管​理​程​式​取​得​主​機​與​客​座​端​的​對​應​資​訊​。​
