Question : ORA-00310

Still trying to get a successful restore test.  I just created a tablespace, switched logfiles a few times to get logs generated, dropped the tablespace switched logs a few more times, shutdown the database and startup mount.  Now oracle is saying the logfile is out of sequence.
I just generated them a few minutes ago with the switch logfiles.  How does it get out of sequence and how do i put it back into sequence?


tabase mounted.

Answer : ORA-00310

see my other post..  
you have to delete the datafile and bring them back from a backup taken before the DROP.

then, apply logs to roll forward.
