Oracle on IBM AIX JFS2 mount options for Async I/O

** Myself
Solution asyn io
- smity aio
- change/show characteristic 
  chage state at boot to available (use ESC + 4 to change)
- ENTER
- mkdev -l aio0
 

“You must mount all JFS2 filesystems containing Oracle datafiles (sapdata directories) with the mount -o cio option.”

Filesystem  datafiles (directory for oradata,sapdata) Need to change

 /etc/filesystems in mark red 

EX.

/oradata:

        dev             = /dev/fslv00

        vfs             = jfs2

        log             = /dev/loglv00

        mount           = false

        options         = cio,rw

        account         = false

“Do not mount JFS2 filesystems holding $ORACLE_HOME, logfiles etc. with the -o cio option!”

But filesystem  on ORACLE_HOME not change to cio
