Some BackUp & Recovery Questions

To manually produce an archive log you use the command:
ALTER SYSTEM SWITCH LOGFILE;



Q. Do you do this once?  Or once for each online redo log group?



Why do you clear logs after recovery using the ALTER DATABASE OPEN RESETLOGS;
Q. I'm not sure when to open resetlogs and when not to open resetlogs.



Why is SHUTDOWN ABORT necessary after the loss of a control file?



Many Thanks



Thiko!
