文档解释
ORA-16439: Standby not ready to receive redo at this time
Cause: A logical standby or down stream capture database was not in a state where it could accept a request to receive redo from another database. This was likely due to the database not being open.
Action: See the database alert log at the receiving side of the transfer for details of why the database was not ready. If the database was mounted but not open, open it to clear the problem. The initialization parameter LOG_ARCHIVE_DEST_STATE_n at the sending site may need to be set to ENABLE.
ORA-16439是一种数据库错误,该错误指示备份数据库(或称为热备份或热应用程序)当前无法接收重做日志,可能是因为它无法验证其当前状态或无法开始验证它对主数据库。
ORA-16439错误的官方解释是:standby not ready to receive redo at this time.
典型的ORA-16439错误案例如下所示:
SQL> alter database recover managed standby database cancel;
alter database recover managed standby database cancel

ERROR at line 1:
ORA-16439: 当前无法接收重做日志
一般处理方法及步骤
1.检查备份数据库的状态。
2.如果备份数据库已经关闭,则使用“alter database open”命令打开它。
3.重启热应用程序服务器(只需在备份数据库中执行)。
4.重新启动复制数据库任务(管理数据库旁路系统,RMAN)。
5.如果错误仍然存在,请检查控制文件,日志文件以及其他相关文件,以确保它们存在并可用。
6.对控制文件/日志文件/其他相关文件进行复制,这可能需要重建旁路系统或RMAN。
7.如果控制文件存在,则重新构建受管理的备份数据库。
8.重启旁路系统/RMAN和备份数据库服务器,以确保可以从主数据库接收重做日志。
