I just learn that start oracle8 control file has "new" feature it cause the size of control file growing, growing...
I am use rman nocatalog (use control file to tracking backup).
what is the relation between rman history in control file and control_file_record_keep_time.
I understand this is a big topic so please let me know how I start the research.
thanks in advance.
When u use Rman nocatalog Controlfile stores information about ur backups through Rman. This information regarding
ur bakup sets,back copy etc will increase as u take bake up day by day.This information is stored in reusale section of
ur control file.
Now Control_file_record_keep_time Parameter applies to reusale section.
It specifies minimum age in days that a records must have before it can be reused.
Then records in reusale section is not used for 3 days.
Any new records for 3 days will be appended in reusable section of control file, but after 3 days these record will be reused if necessary.
And u have to take bakup of ur control file atleaset every 3 days.
