How to check if asynch io is enabled in Solaris?
I am using a 22.214.171.124 db on Solaris 10. The disk_asynch_io is set to true and filesystem_options=asynch. But when we do the truss on the dbw process we find that its calling the pwrite/pread instead aioread and aiowrite calls. In Linux you have to run the following command to enable asynch for Oracle:
cd to $ORACLE_HOME/rdbms/lib
a) make -f ins_rdbms.mk async_on
b) make -f ins_rdbms.mk ioracle
Also in Linux it can be verified if asynch Io is enabled or not by using:
cat /proc/slabinfo | grep kio
I wanted to know how I can check in Solaris weather asynch IO is enabled for Oracle or not. Also if its not enabled how can I enable it?
When in doubt ...go to the basics!!
