Graphical Changes Service Configuration

Launch AVEVA Graphical Changes Service Configuration to display the Graphical Changes Service Configuration window.

Project Configuration

Project configurations can be created, modified and saved from the Project Configuration menu. GCS must be stopped and restarted for the configurations to take effect.

Project

Specifies the AVEVA E3D Design project code.

MDB

Specifies the AVEVA E3D Design Multiple Database (MDB) name.

User Name

Specifies the AVEVA E3D Design project user name.

Password

Specifies the AVEVA E3D Design project user name password.

Server Number

Specifies the number of E3D instances used when creating the cache (more servers may be needed for larger baselines).

Poll Interval (sec)

Specifies the interval, in seconds, between polling for database changes.

Include Elements

A PML expression of elements to be included in baseline.

For example, /E1301, ALL SITE.

Multiple expressions can be input on separate lines).

Save and Close

Saves the configuration information and starts the GCS. A confirmation window displays indicating that the GCS has started.

The configuration information for each project is stored in an xml file at the following location:

C:\Users\Public\Documents\AVEVA\ARFCacheProjects

When GCS is started, each project will be polled at regular intervals for Get Work changes. Only changes which affect the graphics are added to the cache.

The saved password is encrypted but an NT Authenticated (active directory) project may also be used.

Cache Storage

Caches are stored in a separate GCS Cache directory below the project directory.

For Spectrum projects, the cache is stored in the Spectrum project folder on the edge connector.

The baseline cache is stored in the cache0 directory (this should be the largest cache created for the project) followed by a sequence of smaller delta caches.

Create a New Baseline

It may be necessary to create a new baseline if, for example, the number of caches becomes too large, the model has changed significantly or there has been a catalogue change which affects the spatial map. The following procedure can be used:

1. Stop the GCS.

2. Reconfigure projects (if necessary).

3. Delete the GCDCache project directory.

4. Restart the GCS.

When the service is restarted, a new baseline is created and each project is polled for changes.
