11.2RAC的ASM实例上创建10g库报错ORA-29701

在Oracle11.2 RAC 的ASM 实例上创建10g 数据库时，报错说：不能连接到Cluster Manager ，不能定位到ASM 实例。具体错误信息如下：

ORA-15077: could not locate ASM instance serving a required diskgroup

ORA-29701: unable to connect to Cluster Manager

但在该集群上，创建11g 的数据库时是正常的。

我的目标是将10g 数据库迁移升级到11.2RAC 的环境中。首先是在11.2RAC 上恢复好10g 的数据库，再到11g 的RDBMS 环境中去升级。

在恢复控制文件时，就报错。显示不能连接到Cluster Manager 。

Oracle 官方文档对此错误的解释时11gR2 不兼容老版本的数据库。11gR2 的集群配置是动态的，而老版本的库如10.2 版本的库要求集群配置是固定的。

Oracle 官方文档同时也给出了解决方法，即是将css 资源pin 住。

使用root 用户登录操作系统，执行下列命令。

[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 界面去恢复控制文件，正常了。
