其中，AUTO_START=1表示自动启动，如果不为1，则使用以下命令修改：

[oracle@ocm1 public]$ crs_register ora.prodb.prodb1.inst -update -o as=1
[oracle@ocm1 public]$ crs_register ora.prodb.prodb1.inst -update -o as=always

还有一种情况会导致默认启动失败,REQUIRED_RESOURCES为空：

REQUIRED_RESOURCES=

使用以下命令修正：

srvctl modify instance -d -i -s

示例：

srvctl modify instance -d prodb -i prodb1 -s +ASM3
