Re: [suse-oracle] Server Hang, Program or HW?

Dear Anton and All,

Q: 7.How can I disable the Asynchronous I/O?


A: If asynchronous I/O needs to be disabled for some reason, please 
execute the following steps :

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)
