New—HP DFO supports Integrity servers, AlphaServer systems, and VAX systems
As the data on your drives grows, so do performance problems
caused by fragmentation. HP Disk File Optimizer (DFO) automatically reduces
file fragmentation, combating performance lags while ensuring data
integrity. To use disk space efficiently, your OpenVMS file system
fragments files as they are written. As the file and free space
becomes fragmented, disk performance degrades and system performance
deteriorates. HP DFO restores prior performance
levels by defragmenting the files, free space, and index file of
the disk.
HP DFO features an enhanced graphical user interface that
eases the task of establishing and managing defragmentation processes;
places frequently accessed files close together near the index on a volume
and seldom-accessed files farther away, providing the best possible performance;
and lets users defragment the volume index file (INDEXF.SYS) with an offline
utility.
How fragmented are your disks? Following are executables that provide fragmentation reports on your disks. These utilities require
the following privileges: BYPASS, NETMBX, TMPMBX or SYSPRV, and
READALL.
» show_integrity.zip (199 KB) to run the fragmentation report on OpenVMS for Integrity servers
» show_Alpha.zip (155 KB) to run the fragmentation report on OpenVMS for AlphaServer systems
» show_VAX.exe (192 KB) to run the fragmentation report on OpenVMS for VAX systems
After the executables have been downloaded to your OpenVMS system, run the following commands (platform specific).
For Integrity servers: $run show_Integrity.exe
For AlphaServer systems: $run show_Alpha.exe
For VAX systems: $run show_VAX.exe
