GPFS block size
- should be around (256K, 512K, 1024K)
- GPFS block size is the file system stripe size.
- Not that important for regular database I/O since Direct I/O is used.
- Very important for operations that increase data file size.
GPFS pagepool size
Since Oracle on GPFS uses Direct I/O, which bypasses the GPFS “pagepool” for all database file operations including the RMAN utility,
there is no need to increase the GPFS cache.
However, if basic commands such as ‘cp’ or ‘tar’ are used for file maintenance then increasing the “pagepool”may be beneficial. |
