A nice feature of RMAN is that if a restore fails, and you rerun it, it realises that it doesn’t have to redo all the work it has already done.
At least, that is usually what happens.
Today we got:
As documented in oracle support note 2036644.1, this is caused by oracle bug 14683854, and the workaround is to remove
in the Oracle home of the database being copied.
The problem with this is that RMAN starts the whole restore again. And of course, the orginal problem that caused the error is probably still there…
