Talons Purging
  • Sometimes you've got to let everything go -- purge yourself. If you are unhappy with anything . . . whatever is bringing you down, get rid of it. Because you'll find that when you're free, your true creativity, your true self comes out.

Purge files & Lists

  • Selecting this option will prompt with the standard date entry screen, You will then be prompted whether to clear the Unix subdirectory as well. Some text on the screen will remind you of the actions and need to take them.
3
When to Purge

  • Once a period has been fast loaded and it is not expected that the period needs to be re-processed, it can be purged.
4
Consequences of purging to reprocessing

  • If a period is purged, all third party files for that period, such as ORMIS, AUSLAB, PARIS, TRENDCARE, or EDIS, anything that is imported from outside the HBCIS system at all, must be re-loaded.

What Does Purging Do in detail

  • Reality Data files
  • As noted, purging removes period data files from the major data files within TALONS, the major data files store each period as a separate "Data Level", purging deletes that data level, allowing the space to be returned to the unused pool of Realityâ free space. Data levels are created as required and identified to each period. Frequent Purging will minimise the space taken by TALONS in the Realityâ database.
  • POINTER-FILE Lists
  • Realityâ stores selection "queries" as a List of item ID's in a System file called the Pointer file. Purging Deletes these lists that are no longer required. Some lists are not deleted, these keep track of changes for certain functions, the Purge function handles this automatically.
  • Unix Data files
  • TALONS as part of its function creates Unix data files, these are stored as compressed ".Z" files in the TALONS Unix files directory, some of the files in this directory are imported files. The Purge function will delete all files starting with the Sites three letter Campus code and for the specified period. Imported files will not be purged by this function.
  • Not all imported files from the NT FTP box are saved, gradually all Import processes are being modified to delete files after import and processing. Files directly FTP'd to the Unix directory must be managed by the user. Copies of all third party files should be left on the FTP server for as long as it is conceivably possible they may be required, then archived off to some other secure storage location.

Purging at a Multi Account site
  • Sites such as Mater and Redcliffe/Caboolture require that Purging be carried out in each account, as a security feature of Realityâ only allows deletion of Data levels from within the actual account. This is handled by providing a Phantom process launcher to purge files by launching a phantom process in each account to do the task. The Purging is only one of several processes that can be started by this Phantom process starter.
