Tape Compression…
Tape drive compression improves performance
Use media manager environment variable
- Legato is NSR_COMPRESSION
Send value with PARMS on ALLOCATE CHANNEL
Notes:
Tape device data compression can have a very good impact on RMAN performance.
The PARMS parameter of the ALLOCATE CHANNEL command is used to send a command to the tape media manager. In my environment I use the Legato Single Server Edition, which supports the NSR_COMPRESSION environment variable to enable compression. Refer to the lesson “Getting Started with Tapes” for more information on tape manager environment variables.
