ORA-25533: FAST_START_IO_TARGET or LOG_CHECKPOINT_INTERVAL is specified

文档解释

ORA-25533: FAST_START_IO_TARGET or LOG_CHECKPOINT_INTERVAL is specified

Cause: An attempt to start MTTR advisory was made, which failed because either FAST_START_IO_TARGET or LOG_CHECKPOINT_INTERVAL was specified.

Action: Set FAST_START_IO_TARGET and LOG_CHECKPOINT_INTERVAL to 0.

ORA-25533是Oracle数据库的一个错误消息，表明您同时指定了FAST_START_IO_TARGET参数和LOG_CHECKPOINT_INTERVAL参数。

官方解释

ORA-25533错误表明您不能同时设置FAST_START_IO_TARGET参数和LOG_CHECKPOINT_INTERVAL参数。指定FAST_START_IO_TARGET参数使数据库主机在重新启动后以恢复到正常操作所需的最短时间恢复服务，而LOG_CHECKPOINT_INTERVAL参数则用于控制数据库日志文件自动检查点之间的时间间隔。

常见案例

ORA-25533错误是当通过ALTER SYSTEM语句指定FAST_START_IO_TARGET参数和LOG_CHECKPOINT_INTERVAL参数，或者当PFTRACE运行时自动指定这些参数时可能出现的错误。

一般处理方法及步骤

1. 检查当前PFTRACE状态，使用命令ALTER SYSTEM SET PFTRACE=OFF SCOPE=SPFILE;

2. 删除FAST_START_IO_TARGET参数，使用命令ALTER SYSTEM SET FAST_START_IO_TARGET=”” SCOPE=SPFILE;

3. 重新启动数据库，使用命令SHUTDOWN IMMEDIATE;STARTUP;
