Goal

Issue: RMAN is creating more backup peices then expected ?

This is an issue on 8i and onward versions of RMAN. When performing backup, we can get multiple backup sets.
However, you are expecting all the files to be in one backup set. The 'FILEPERSET' is not set in the RMAN script.
According to  documentation, if 'FILESPERSET' is not set in the RMAN script, than up to 65 files will be put in one backup set.
