Dear,
his solution..
AIX 6.1 with Oracle >= 11.2.0.2:
AIX 6.1 introduced a new open flag O_CIOR which is same as O_CIO, but this allows subsequent open calls without CIO. The advantage of this enhancement is that other applications like cp, dd, cpio, dbv can access database files in read only mode without having to open them with CIO.
Starting with Oracle 11.2.0.2 when AIX 6.1 is detected, Oracle will
use O_CIOR option to open a file on JFS2.
Therefore you should no longer mount the filesystems with mount option -o cio
Please remove the mount option "-o cio" if you are running Oracle 11.2.0.2 on AIX 6.1 to avoid the following error messages:
cp: A system call received a parameter that is not valid.
0653-902 Cannot open the specified file for reading.
DBV-00100: Specified FILE not accessible
errno(22) A system call received a parameter that is not valid.
I Need step by step, because I newbie..
