PRODUCT NAME: HP Disk File Optimizer SPD 55.85.14

for OpenVMS,Version 2.9

DESCRIPTION

HP Disk File Optimizer (DFO) for OpenVMS is a layered

software product which reduces both ﬁle fragmentation

and free space fragmentation and optimizes ﬁle place-

ment on disk media. This results in better application

performance, better backup performance, and more ef-

ﬁcient disk utilization.

DFO operates in two modes. In "Defrag PLUS" mode,

RMS is used as a database of scheduling information,

and defragmentation jobs can be scheduled using a

wide variety of scheduling criteria. In normal "Defrag"

mode, defragmentation jobs are run when requested

by the user. The user or system manager can spec-

ify which of these two modes should be used when the

product is installed.

The key capabilities of DFO for OpenVMS are:

• Reduces ﬁle fragmentation and free space fragmen-

tation for disk devices

• Provides the ability to defragment speciﬁc ﬁles or an

entire disk

• Gives the user the capability to select or exclude spe-

ciﬁc ﬁles based on:

— User choice

— Severity of fragmentation

— Whether the ﬁle has placement pointers

— Whether the ﬁles are indexed

• Provides event based scheduling of defragmentation

jobs

• Provides a Monitor function which allows File Opti-

mizer processes to be monitored while in operation

• Allows pre- and post-processing commands to effect

automation of tasks before and after defragmentation

jobs are executed

• Gives the user the ability to classify ﬁles as "hot" (fre-

quently accessed), or "cold" (infrequently accessed)

and to have them placed on the disk drive accord-

ingly

• Provides two modes of operation to tailor to the spe-

ciﬁc customer environment

• Offers a choice of Digital Command Line (DCL) or

Motif-based Graphical User Interfaces. This is avail-

able for both Defrag and Defrag PLUS modes.

• Provides an ofﬂine defragmentation utility that allows

the user to defragment INDEXF.SYS on a disk device

that is not mounted. For a bound volume set this

utility only works on the "ROOT" volume.
