ORA-07264: spwat: semop error, unable to decrement semaphore.

这是由Oracle数据库产生的操作系统错误,用于提醒操作系统出现内部错误,通常由于下列原因造成:

-操作系统错误,例如系统宕机;

-资源或系统限制,如实例限制,存储空间等;

-服务器时间变动;

-硬件错误,如磁盘崩溃,缓存等;

-系统维护……

正常处理方法及步骤

1.检查与semaphore相关的资源及权限,如是否进行服务器维护;

2.检查系统实例、资源限制,确定系统没有性能瓶颈;

3.检查硬件状态,看是否有磁盘空间或者缓存出现故障;

4.再次检查时间是否同步。
