Reconfiguration Process

Reconfiguration : Reconfiguration Process

Reconfiguration is a two-pass operation, acting on either a complete database or on specified parts of one.

In the first pass, RECONFIGURER scans a named source database and copies the data for some or all existing elements and their attributes into intermediate files.

In the second pass, the contents of the intermediate files are transferred to a specified destination database.

This mode of operation has the following features:

•

Only existing elements are copied to the intermediate files; deleted items and corrupt data are ignored. The destination database created from these files is therefore both compact and uncorrupted.

•

The reference and non-reference attributes of the elements are held in different intermediate files. The method of transfer of data to the destination database makes sure that all referencing is complete and consistent.

•

The source and destination databases may have different DDLs. This enables existing data to be restructured to conform to a new database structure and so, for example, to be used with a new version of AVEVA E3D™.

•

Reconfiguration can used to transfer a project to different hardware. The intermediate files produced by the first stage can be decoded into a portable format (typically ASCII), and transferred, and then the second stage carried out.
