D3 File Sizer Utility

Use the D3 File Sizer Utility to resize D3 files automatically or manually. The D3 File Sizer Utility uses the file-of-files, which is updated by the file-save command.

The file-of-files contains statistical information for each file on the system. Whenever a file is created, restored, or deleted this file is updated.

If you are already familiar with the D3 File Sizer Utility, see D3 File Sizer Utility Commands as a quick reference.

Automatic Resizing

The D3 File Sizer Utility automatically resizes D3 database files through the use of the Background Monitor. At user specified intervals, the Background Monitor analyzes the size of files in:

  • Specified account

  • Individual files

  • Entire system

and automatically resizes them to ensure proper system performance.

Manual Resizing

The D3 File Sizer Utility also allows the manual resizing of files at any time. The user can build a list of selected files to resize, and view information about individual files. Files can be resized manually regardless of Background Monitor status.

Resizing Files with the Background Monitor

The Background Monitor tracks files on your database daily, weekly, or monthly (depending on how often you specify) to ensure that they are sized according to the default maximum ratio or according to individually set maximum ratios.

The following options may be edited by the user:

  • Wake-up date

  • Wake-up time

  • Check files (specifies how frequently the files are checked)

  • Day of month

  • Day of week

  • Monitor

  • Default Maximum Fill

  • Default Action

Resizing Individual Files

Files can be resized on an individual basis at any time. To track the files being resized, build a list of selected files. Using the list of selected files, you can view individual file information, search the list for a specific character string, or resize a file.

File statistics displayed within the various D3 File Sizer screens are regenerated by performing a file-save or account-save, running the D3 File Sizer Utility, then performing another file-save or account-save. Detailed instructions are provided in the remaining pages of this document (see Viewing File Information).
