Mounting a Volume With Caching Disabled  



To prevent the file system from caching data on a particular volume, such as a database volume, use the MOUNT /NOCACHE command to mount the volume with caching disabled.

If you are using XFC in an OpenVMS Cluster, mounting a volume /NOCACHE is easier than using SET FILE /CACHING_ATTRIBUTE to set the caching attribute of all the files in the volume to no caching (see Disabling Caching for a File). Using MOUNT /NOCACHE ensures the minimum caching overhead. Note that the MOUNT/NOCACHE command also disables XQP caching.

Example

This example mounts a database volume labeled ORACLE_VOL1 with caching disabled: 

$ MOUNT DUA100: ORACLE_VOL1 /NOCACHE /SYSTEM
