The installation procedure automatically selects the correct version. In addition, there are two variants of the product itself: o Defrag o Defrag PLUS The installation procedure allows you to choose to install Defrag or Defrag PLUS software. Defrag PLUS contains a scheduling process that allows for periodic scheduling of defragmentation jobs. If you do not wish to use the Defrag PLUS, install the Defrag variant. Defrag provides a more direct interface to the defragmentation process. Customers are adviced to take backup of the existing database before deinstalling the earlier versions of DFO. 2 Software Version Requirements Disk File Optimizer (DFO) for OpenVMS, Version 2.9 software runs on OpenVMS VAX Version 7.3, on OpenVMS Alpha Versions 7.3-2 & 8.2 and on OpenVMS I64 Version 8.2. 3 Installing the Software The following steps should help you begin the installation procedure for installing Disk File Optimizer for OpenVMS V2.9 on your system.

Also the fix of CFS 104353 for DFG 2.7 ECO doesn't solve this problem in all cases. This problem was reported in CFS.106493 and is fixed in this release. 5 Known Problems and Restrictions This section describes known problems and restrictions for V2.9 of the Disk File Optimizer for OpenVMS. 5.1 Mounting or dismounting the disks Restriction Mounting or dismounting the disks cannot be done through the command file specified in the /PROLOGUE or /EPILOGUE as these sub processes are created with minimal privileges. 6 Truncating Directories There has been a couple of requests to have Disk File Optimizer truncate directories. Instead of adding this feature to DFO, you should use the SET FILE/TRUNCATE DCL command. Directories never shrink they only grow. Even though you delete files in a directory, the allocated space for a directory stays the same. The following shows an example using the SET FILE/TRUNCATE command to truncate a directory: $ DIRECTORY/SIZE=ALL DIR/SIZE=ALL [SLICK]MAIL.DIR Directory DSA422:[SLICK] MAIL.DIR;1 115/140 $ SET FILE/TRUNCATE [SLICK]MAIL.DIR $ DIR/SIZE=ALL [SLICK]MAIL.DIR Directory DSA422:[SLICK] MAIL.DIR;1 115/116 Total of 1 file, 115/116 blocks. 4 Notice in the above example that the directory is 140 blocks in size but the end of file is at block 115. The directory is then truncated to 116 blocks with the SET FILE /TRUNCATE command. 5
