I'd like to test Flash Cache Feature on 11gR2(patch 8974084) on Linux.

I use:
OS: RHEL 5.3.
Oracle Version: 11.2.0.1.0 (x86_64)
$ opatch lsinventory
Invoking OPatch 11.1.0.6.6

I use Sun Storage Flash Array and mount it.

$ mount -t vfat -o noauto,users,rw,umask=000 /dev/sdb1 /u01/app/flash_cache/ $ df
/dev/sdb1 23G 16K 23G 1% /u01/app/flash_cache

But I found error:
ORA-00439: feature not enabled: Server Flash Cache ORA-01078: failure in processing system parameters

Parameters:
*.db_flash_cache_file='/u01/app/flash_cache/file01.dbf' *.db_flash_cache_size=10G

What I should to do with Operating System or Disk?
