-- Common parameters for RMAN procedures
p_directory_name: The name of the directory to contain the backup files.
p_label: A unique string that is included in the backup file names.
p_compress: Specify TRUE to enable BASIC backup compression. (No Advanced Compression Option required)
p_include_archive_logs: Specify TRUE to include archived redo logs in the backup. (default is False)
p_include_controlfile: Specify TRUE to include the control file in the backup. (default is False)
p_optimize: Specify TRUE to enable backup optimization, if archived redo logs are included, to reduce backup size. (default is True)
p_parallel: Number of channels. (default is 1)
p_rman_to_dbms_output When TRUE, the RMAN output is sent to the DBMS_OUTPUT plus a file in the BDUMP directory. (Default is False)
p_section_size_mb The section size in megabytes (MB).
p_validation_type Specify 'PHYSICAL+LOGICAL' to check for logical inconsistencies in addition to physical corruption. (Default is PHYSICAL)
