Hi
there...
i have some doubt here.googled it many times but couldn't find anything..

i invoked RMAN and issued the folowing command..


RMAN> list expired archivelog all;

using target database control file instead of recovery catalog
specification does not match any archived log in the repository

so it says that "using target database control file instead of recovery catalog"
1)does this mean
that my database has a recovery catalog???

2)if i want to delete the expired archive log how can i do that??

3)if recovery catalog is created for my database how can i connect it again??


But when i issued CROSSCHECK ARCHIVELOG ALL;

i got listed some files what does this mean??Is it better to use "CROSSCHECK ARCHIVELOG ALL"
INSTEAD OF "LIST EXPIRED ARCHIVELOG ALL"??

And,These are my RMAN setting for the database..
