如何解決Oracle12c單實例環境無法創建asm磁盤組問題

這篇文章給大家分享的是有關如何解決Oracle12c單實例環境無法創建asm磁盤組問題的內容。小編覺得挺實用的，因此分享給大家做個參考，一起跟隨小編過來看看吧。

Oracle12c單實例數據庫通過asm進行安裝配置，在asmca創建asm磁盤時出現Oracle Grid Infrastructure is not configured properly. ASMCA needs Oracle Grid Infrastructure to configure ASM提升信息，截圖如下所示：

從上面的問題我們可以很清晰的看到是因為ASMCA無法連接到OracleGrid Infrastructure而導致無法創建。檢查has進程，確定其已經起來，此處我的環境has是未起來的，重新執行

/u01/app/12.1.0/grid/crs/install/roothas.pl ，如下所示：

[root@localhost ~]# /u01/app/12.1.0/grid/crs/install/roothas.pl

Using configuration parameter file: /u01/app/12.1.0/grid/crs/install/crsconfig_params

再次通過asmca創建asm磁盤組，可以成功創建，結果如下圖所示。
