nid更改dbid时的NID-00135错误
Oracle Error :: NID-00135
There are number active threads
Cause
is that the database crashed the last time it was shut down.
Action
Ensure that all threads are closed before retrying the operation. Start and open the database to perform crash recovery, then shut down with the NORMAL or IMMEDIATE options to close it cleanly. Finally, try running the utility again.

4、通过bbed修改dbid
分成两步执行，否则会出现错误BBED-00209: invalid number (0x9b87fb03)
set offset 28
modify /x 9b87
set offset 30
modify /x fb03
sum apply
修改完毕再次检查dbid正常
