Quick I/O Summary
To increase database performance on a VxFS file system using Quick I/O:
1. Make sure that the VERITAS Editions product is installed:
# swinstall | grep VRTSdbed
2. Make sure that the VERITAS Quick I/O package is licensed:
# vxlicrep | VXFDD
3. Create a regular VxFS file and preallocate it to required size, or use the qiomkfile
command. The size of this preallocation depends on the size requirement of the database
server.
4. Create and access the database using the file name xxx::cdev:vxfs:.
For information on how to configure VxFS and set up file devices for use with new and
existing Oracle databases, see the VERITAS Editions product documentation, and the
qioadmin(1) and vxtunefs(1M) manpages.
