DIGITAL Software Product Description ___________________________________________________________________ PRODUCT NAME: Disk File Optimizer SPD 55.85.06 for OpenVMS, Version 2.4 DESCRIPTION The Disk File Optimizer (formerly named POLYCENTER File Optimizer) for OpenVMS is a layered software product which reduces both file frag- mentation and freespace fragmentation and optimizes file placement on disk media. This results in better application performance, better backup performance, and more efficient disk utilization. Disk File Optimizer 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 specify which of these two modes should be used when the product is installed. The key capabilities of the Disk File Optimizer for OpenVMS are: o Reduces file fragmentation and freespace fragmentation for disk de- vices o Provides the ability to defragment specific files or an entire disk o Gives the user the capability to select or exclude specific files based on: - User choice - Severity of fragmentation - Whether the file has placement pointers - Whether the files are indexed October 1998 AE-Q6M7G-TE o Provides event based scheduling of defragmentation jobs o Provides a Monitor function which allows File Optimizer processes to be monitored while in operation o Allows pre- and post-processing commands to effect automation of tasks before and after defragmentation jobs are executed o Gives the user the ability to classify files as "hot" (frequently accessed), or "cold" (infrequently accessed) and to have them placed on the disk drive accordingly o Provides two modes of operation to tailor to the specific customer environment o Offers a choice of Digital Command Line (DCL) or Motif[R]-based Graph- ical User Interfaces. This is available for both Defrag and Defrag PLUS modes. o 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. HARDWARE REQUIREMENTS Disk File Optimizer is a layered software product on the OpenVMS op- erating system for both VAX and Alpha hardware platforms. The list of supported processors and hardware configurations is the same as those supported by OpenVMS and mentioned in the following Software Product Descriptions (SPDs). OpenVMS VAX Operating System SPD (25.01.xx) OpenVMS Alpha Operating System SPD (41.87.xx) Processors Not Supported MicroVAX I, VAXstation I, VAX-11/725, VAX-11/782, VAXstation 8000 Processor Restrictions: The MicroVAX 2000 and VAXstation 2000 systems require a TK50 for a load device. 2 A minimum system configuration to run Disk File Optimizer includes: o 4 MB memory o One or more tape drives (TK50 or 9-track) supported by OpenVMS o One or more disk drives supported by OpenVMS Disk Space Requirements (Block Cluster Size = 1) Disk Space Requirements for Defrag PLUS For installation 7,000 blocks (3.6 MB) on VAX: For permanent use 3,700 blocks (1.9 MB) on VAX: For installation 12,000 blocks (6.2 MB) on Alpha: For permanent use 7,800 blocks (4.0 MB) on Alpha: Disk Space Requirements for Defrag For installation 3,900 blocks (2.0 MB) on VAX: For permanent use 2,800 blocks (1.5 MB) on VAX: For installation 7,800 blocks (4.0 MB) on Alpha: For permanent use 3,900 blocks (2.0 MB) on Alpha: These counts refer to the disk space required on the system disk. The sizes are approximate; actual sizes may vary depending on the user's system environment, configuration, and software options. 3 SOFTWARE REQUIREMENTS o OpenVMS VAX Operating System (Version 5.5-2, 6.2 and 7.1) or Open- VMS Alpha (Versions 6.2 and 7.1) o DEC C/C++ runtime kit (included with the Disk File Optimizer kit) is only required for OpenVMS Version 5.5-2. OpenVMS Tailoring For OpenVMS V5.x systems or OpenVMS Alpha V6.x systems, the follow- ing classes are required for full functionality of this layered prod- uct: o OpenVMS Required Saveset o Programming Support o Utilities o System Programming Support o Secure User's Environment o Network Support o OpenVMS Workstation Support For more information on OpenVMS classes and tailoring, refer to the OpenVMS VAX Operating System Software Product Description (SPD 25.01.xx) or the OpenVMS AXP Operating System Software Product Description (SPD 41.87.XX). OPTIONAL SOFTWARE o POLYCENTER Performance Data Collector for OpenVMS V2.1 or later. The POLYCENTER Performance Data Collector and POLYCENTER Perfor- mance Advisor software are required to use the automated hot file placement option. This capability requires a valid license for POLY- CENTER Performance Data Collector but does not require purchase of 4 a license for POLYCENTER Performance Advisor. The binaries for both the POLYCENTER Performance Data Collector and POLYCENTER Perfor- mance Advisor must be accessible to Disk File Optimizer. These bi- naries are available on the OpenVMS Software Product Library on CD- ROM (see the ORDERING INFORMATION section for part numbers). In or- der for Disk File Optimizer to place "hot" files using data sup- plied by POLYCENTER Performance Data Collector and POLYCENTER Per- formance Advisor, the Disk File Optimizer must be running on a sys- tem that also has the POLYCENTER Performance Advisor and POLYCEN- TER Data Collector installed on it. o VMS DECwindows Motif V1.1 or later. VMS DECwindows Motif is part of the OpenVMS Operating System but must be installed separately. Installation of VMS DECwindows Mo- tif gives you the option to use the Disk File Optimizer graphical user interface. SOFTWARE LICENSING This software is furnished only under a license.
