Solution

Applies to:

Oracle Database - Enterprise Edition - Version 10.2.0.1 to 11.2.0.1 [Release 10.2 to 11.2]
IBM AIX on POWER Systems (64-bit)
IBM AIX Based Systems (64-bit)
***Checked for relevance on 13-Sep-2013***

Symptoms

On AIX 6.1, when checking for AIO settings using the "/usr/sbin/lsattr -El aio0" command it returns the following error:

% /usr/sbin/lsattr -El aio0
lsattr: 0514-519 The following device was not found in the customized
device configuration database:
aio0

Cause

The method of checking how asynchronous I/O is configured has changed in AIX 6.1

Solution

On AIX 6.1 you must use this command instead:

/usr/sbin/ioo -a | grep aio


Example results:

io_active = 1
aio_maxreqs = 65536
aio_maxservers = 30
aio_minservers = 3
aio_server_inactivity = 300
posix_aio_active = 1
posix_aio_maxreqs = 65536
posix_aio_maxservers = 30
posix_aio_minservers = 3
posix_aio_server_inactivity = 300


The /usr/sbin/chdev command can still be used to make any changes to the configuration (as per AIX 5L)
