Oracle Advanced Compression option

The Oracle Advanced Compression option contains the following features:

• Data Guard Network Compression
• Data Pump Compression (COMPRESSION=METADATA_ONLY does not require the Advanced Compression option)
• Multiple RMAN Compression Levels (RMAN DEFAULT COMPRESS does not require the Advanced Compression option)
• OLTP Table Compression
• SecureFiles Compression and Deduplication

The default RMAN compress (BZIP2 algorithm - higher compression ratio but high CPU usage) does not requires the advanced compression option license. The ZLIB algorithm (less compression ratio but lower CPU usage) requires the license.
