What is meant by 'Bounce' the database

Hello, 

What is meant by 'Bounce' the database. I keep coming across the phrase. 

Usually after changing some parameter/setting, the paper/manual will ask us 

to 'bounce' the database (i guess, instead of shutting down the database and 

restarting it). 

How do we bounce the database. 

Thanks, 

Tom

Careful. Somebody said that 'bounce' means to 'shutdown abort' and restart. 

This is not necessarily correct. Shutdown abort should NOT be used unless 

absolutely necessary. Most shutdowns can be accomplished with a 'shutdown 

immediate' (shutdown normal will wait for certain activities to finish which 

may delay your shutdown too much). 'shutdown abort' will not issue a 

checkpoint and will not synchronize all the data and control file headers. 

when you restart the database after a shutdown abort it will perform 'media 

recovery' and resychronize everything. if you have problems doing a 

shutdown immediate then go ahead and do a shutdown abort.
