Compare/Update User Guide

Options and Mapping : Link Database Administration including Global Projects

All Compare/Update users require write access to a single Link World (CYMWRL). If this is not present when a Link function is performed then Compare/Update will return an error. Project administrators are recommended to use the following procedures:

•

Create a separate Design Reference database in Admin, and ensure it is current on all MDBs for Compare/Update users, and all Compare/Update users can write to it.

•

Use Manage Links to create a Link World in the new database, or to merge links from an old link world (prior to 12.1 link worlds resided in Design databases).

•

For a global project, create variant extracts of the link world database and make one extract primary at each location that needs to use Compare/Update. This will ensure the link data can be issued back to the parent db and combined from the various locations with no claim conflicts.

Links created prior to 12.1 reside in Design databases. These must be migrated to Design Reference databases in order to be used by Compare/Update in schematic and engineering modules. Project Administrators are recommended to use the following procedures:

•

If using extract databases, then in PDMS DESIGN or Marine Outfitting, use the Extract Control form to select the existing CYMWRL and issue all changes. Repeat this step for all levels of extract database. The next step should then be carried out in the parent database.

•

In PDMS DESIGN or Marine Outfitting, use Manage Links to merge links from the Design database to a new Design Reference database (e.g. by drag and drop). Then click on the Design database and delete the old Links.

•

Refresh any extracts of the Design and Design Reference databases.

When working in an extract database, issuing, flushing or dropping an element that has a referencing link will automatically include the link object. The reference array attribute INCFLU (include flush) returns any link elements that reference the current element. Flushing, issuing or dropping an element with referencing link objects will act on those link objects even if the element itself is not claimed or modified. The Extract Control form will display an "R" label on such elements.
