at.
0509-192 Examine .loader section symbols with the
'dump -Tv' command.
a search in goggle prompt me to check my aio.. indeed, it was not available. so i have to change it and restart it.
1) is there any way to change the aio status other than restart the box?
2) what are the error messages linked to aio?
thanks

If you really do not wish to reboot, you could change the database init.ora parameter disk_asynch_io to FALSE to disable the use of asynchronous I/O within the database. You can simulate Asynchronous I/O by adding DBWRs.
Check this link for details:
http://metalink.oracle.com/metalink/...T&p_id=47328.1
.
However, I would strongly advise you to take advantage of aio and reboot if necessary.
Your questions on aio and rebooting the server are probably better suited to a UNIX forum somwhere.

the Oracle Home have not been set on unix environment.
Please set the Oracle_home on unix environment and export it.
then it works.

It depends on your operating system and Oracle version.
A new Oracle install on AIX 64 bit mode perhaps?

is this really the root cause? i did a reboot and everything is fine.
