  Sorry to bother again.A while ago, I was questioning my restore the DB with RMAN from Prod to Standby and you said that I need to create a backup catalog of Prod, so I can do this
rman target=sys/passwordcatalog=rman/rman

1. I am puzzled how my standby rman knews where is the location of the catalog that Production created.Do I have to modify the parameters of rman (show all)of the Standby to point to the new location where RMAN of Product is stored?
2. When I did my RMAN of Prod (with full database) does that include the catalog also? or Do I have to rman backup it separately?
3.Do I have to use the "SET .. RENAME " to give the new place for the datafile? Can I used the current dir of the Standby for the restored datafiles?

[COLOR=blue]Catalog数据库最好是独立于生产数据库之外的,并且需要独立备份[/COLOR]

[COLOR=blue]如果从库和主库备份时的路径相同是可以的,否则需要指定恢复位置。[/COLOR]

  9i 9206数据库,出现enqueue HW等待,最后确定是在lobsegment段上,该段是blob字段类型系统生成的段,请问如何能够减少HW等待,何原因造成的呢?HW是由于更新HWM造成的等待吗?看了一些文章,说手工分配extent可以起到作用,表示不理解,分配区并不会移动HWM,HWM不是只有在HWM以下没有足够空闲空间时才会移动吗?

  你好。两地灾备,通过Oracle10gDG来实现,如果灾备的Oracle要一直处于open状态(readonly),采用LogicalStandby是否可行?如果两地距离比较远(上百km),数据传输只是2M的,是否有问题。另说LogicalStandby不太稳定,不知你这边是否有这样的案例?

谢谢!

如果用11g是最好的,Physical的也可以打开访问。
Logical的也可以用,问题多一点而已!

  老鹰好,
我在学习使用statspack的过程中,发现以stats开头的表有68个,但是参考手册上没有这些表的解释,我自己也对这些表的具体含义不是很清楚,您能不能提供一点资料让我们了解一下这些表的具体含义。谢谢

  盖老师:你好!
我在看tom的书《oracle 9i&10g编程》一书中第六章说到:删除父表中的一行可能导致子表被锁住,我对此话很奇怪,而我看书中的例子实际上是说明一个问题:修改一个不带外键索引的子表会堵塞其它会话对父表的修改。反过来我就有点不理解。而我始终没有找到修改父表会堵塞对子表的修改的例子。不知道能不能给我一点启示。多谢!
