All,

Here is the script directly out of the TDP for Oracle manual:

To remove an old backup, issue this command from the RMAN
prompt:
run
{
allocate channel for delete type 'sbt_tape' parms
'ENV=(TDPO_OPTFILE=c:\RMAN\scripts\tdpo.opt)';
change backupset primary_key delete;
}
Note: To enter a number value for the primary key variable, look up
the value in the RMAN catalog.


My question is: what exactly is the "primary key" variable?
