Description
When performance issues arise, it can often be difficult to pinpoint the cause. This is especially true when the issues are within the OpenVMS file system. The FAD utility looks at the locking activity taken place within the file system. This data allows the utility to show what files have the greatest amount of activity. The tool has recently been enhanced to show latency information for the file system locking activity as well the longest hold times seen for specific files by the processes accessing the files. This talk will discuss various details of the the OpenVMS File system. FAD types of data available from the FAD utility will be shown along with how it can help identify file system performance issues.
