Using Oracle 10gR2 Database and RMAN with a recovery catalog we are unable to remove all
obsolete records. The command 'DELETE FORCE OBSOLETE' executes and completes without error
or warning but there are still 1000s of obsolete records.


CONTROL_FILE_RECORD_KEEP_TIME=0  # causes the problem because the record sections in the
controlfile cannot expand when the parameter value is 0. Changing the value back to 7 resolved the problem.
The solution section explains why.
