Unfortunately I can't use only a single array. I gave only a simplified example (code) in my question. In fact, I parse the two outputs:
(1) Output log file from Oracle RMAN session, where I've informations about the channels. For example:

allocated channel: ch1
channel ch1: SID=208 device type=DISK
allocated channel: ch2
channel ch2: SID=403 device type=DISK
channel ch1: specifying datafile(s) in backup set
input datafile file number=00014 name=/foo/oradata/bar/foodb-lob01.dbf
input datafile file number=00008 name=/foo/oradata/bar/foodb-index11.d
+bf
(...)
channel ch2: specifying datafile(s) in backup set
input datafile file number=00004 name=/foo/oradata/bar/tools01.dbf
input datafile file number=00019 name=/foo/oradata/bar/foodb-data02.db
+f
input datafile file number=00003 name=/foo/oradata/bar/undotbs01.dbf

(2) The output from `RMAN> list backup` command, where I've a lot of informations about the backups. For example:

So, first (1) goes to the "%files_by_channel" array, and second (2) goes to the "%files_by_number" array. But like I said before, this is just a simplified example, because the "%files_by_number" array contains much more information than I showed. It was interesting only for me how to combine information from these two hash arrays.
