Info

Enable asynchronous io. Install “opatch” utility (2617419) Apply the patch 3016968 which is necessary to enable asych_io. Recompile the kernel to enable access to libaio and skgaioi.o. cd to $O<strong>RAC</strong>LE_HOME/rdbms/lib make -f ins_rdbms.mk async_on make -f ins_rdbms.mk ioracle Make sure that all <strong>Oracle</strong> datafiles reside on filesystems that support asynchronous I/O. (For example, ext2, ext3, ocfs in RedHat 3) or on raw device. Set init.ora file or spfile.ora 'disk_asynch_io=true' ‘filesystemio_options=asynch' (if dbf are on file system) 86
Direct I/O Support • Direct I/O support is not available and is not supported on Red Hat Enterprise Linux 2.1 and SuSE Linux Enterprise Server 8. It is available and is supported on Red Hat Enterprise Linux 3 if the driver being used on the system supports varyio. To enable direct I/O support: • Set the FILESYSTEMIO_OPTIONS initialization parameter to DIRECTIO. • If you are using the asynchronous I/O option, set the FILESYSTEMIO_OPTIONS initialization parameter to SETALL. 87
