ORA-38855: cannot mark instance string (redo thread string) as enabled
Cause: The standby switchover or failover operation failed because it needs to mark an instance (redo thread) as enabled. However, it had less than 2 online redo logs, which prevented it from being enabled.
Action: Add more logfiles to the specified instance and retry the command.
ORA-38855错误(不能将实例字符串(重做线程字符串)标记为启用),通常指实例(instance)的选项无法被修改,以使重做线程(redo thread)具有可用状态。
1、检查实例的配置参数,确保正确配置。
2、重启数据库实例,尝试重置其状态,以重新启用重做线程。
3、检查重做线程日志,检查可能的失败原因。
4、更改实例状态,并尝试给实例添加重做线程。
