Dear Anton and All,

How about libaio in the kernel should I disable it?

And how to install Oracle 10gR2 without Async I/O?
Because according to Metalink, installation Oracle 10gR2 by default 
Async I/O is TRUE.

A.
Uncheck module libaio on install SLES? And install Oracle 10gR2, this 
is make Async I/O disable?

B.
Installation normal and do :


Or still we need to run this :

1) cd to $ORACLE_HOME/rdbms/lib

a) make -f ins_rdbms.mk async_off

b) make -f ins_rdbms.mk ioracle


2) set 'disk_asynch_io=false' (default value is true)




Rgds,
cung
