文档解释
ORA-19550: cannot use backup/restore functions while using dispatcher
Cause: Attempted to use backup/restore functions while connected to the dispatcher in a shared server. This is not allowed because the device that is used for backup and restore must remain allocated to a single process.
Action: Connect directly to the instance then re-execute the backup or restore function.
ORA-19550: cannot use backup/restore functions while using dispatcher错误是当一个数据库实例正在使用分发器时,不能使用备份/恢复功能,这是由于备份/恢复操作导致实例无响应,并且关闭分发器会中断客户机与数据库实例之间的连接。
官方解释
常见案例
一般处理方法及步骤
1、若需要进行备份/恢复操作,应首先关闭数据库实例上的分发器。
2、在分发器被关闭后,可以进行备份/恢复操作。
3、在操作完成后,可重新启动分发器以通知客户机和数据库实例之间的连接。
