10g資料庫例項使用11g asm錯誤問題處理

n-lauren發表於2016-11-17
資料庫ASM
在Oracle11.2 RAC 的ASM 例項上建立10g 資料庫時，報錯說：不能連線到Cluster Manager ，不能定位到ASM 例項。具體錯誤資訊如下：
ORA-15077: could not locate ASM instance serving a required diskgroup
ORA-29701: unable to connect to Cluster Manager


我的目標是將10g 資料庫遷移升級到11.2RAC 的環境中。首先是在11.2RAC 上恢復好10g 的資料庫，再到11g 的RDBMS 環境中去升級。
在恢復控制檔案時，就報錯。顯示不能連線到Cluster Manager 。

Oracle 官方文件對此錯誤的解釋時11gR2 不相容老版本的資料庫。11gR2 的叢集配置是動態的，而老版本的庫如10.2版本的庫要求叢集配置是固定的。
Oracle 官方文件同時也給出瞭解決方法，即是將css 資源pin 住。
使用root 使用者登入作業系統，執行下列命令。
[root@serv2 bin]# ./crsctl pin css -n serv1 serv2
CRS-4664: Node serv1 successfully pinned.
CRS-4664: Node serv2 successfully pinned.
[root@serv2 bin]#
[root@serv2 bin]# ./olsnodes -t
serv1   Pinned
serv2   Pinned

再回到RMAN 介面去恢復控制檔案，正常了。
RMAN> restore controlfile from '/u02/rman_211/ctl_1un9u0a4_1_1.20120501';

Starting restore at 04-MAY-12
