Level 1 incrementally updated backup + "no obsolete backups found" + control file size.

 Hi All,

I posted "RMAN-06053 And Recovery." previously and no reply on that one so far.

During researching the same issue, I found that I have large no. of BACKUP RECORDS in the control file. I had this incrementally updated backup for quite sometime now. And currently I see following in V$controlfile_record_section:


===TYPE=====        ==RecTotal=  =RecUsed=
BACKUP SET                  3272 3272
BACKUP PIECE          3200 3200
BACKUP DATAFILE          9024 9024
BACKUP REDOLOG          2150 1930
BACKUP CORRUPTION  371          0
BACKUP SPFILE          454          454



1> Is above table unusally large? 
2> Should I go for a fresh level 0 incremental backup and start from that again?
3> My current control file size is 45MB. Will doing (2) clear out any of the records above and readjust controlfile size OR I must recreate it manually? 

Howdy, Stranger!
