Through this query we can get for how many days AWR reports maintaining, If that which we did not require that many days we can reduce it. For Example : If we have more than 7 days,we can reduce it to 7 day which is 7*24*60 = 10080 minutes.the retention period is modified to 7...

这种情况往往出现在我们还无法预估将要插入的数据量时,除了个一个极大的表空间或自动扩展来解决之外。 Oracle还为我们提供了一个很好的功能:resumable 在resumable开启的情况下,如果Oracle执行某一个SQL申请不到空间了,会话会暂停,开始等待有空间可用,(等待 时间可以由TIMEOUT来控制),等你把空间的问题解决了,Oracle会...
