CSE Installation and Configuration › CSE Installation Overview › Servers

Servers

The Coordination Server and the Encyclopedia Server each manage a specific database and have processes and utilities that access their corresponding database. The Construction Server also accesses the Encyclopedia database, but it is not involved in its management.

Coordination Server

Manages the Coordination Database that stores information about the encyclopedias and users in the encyclopedia network. The Coordination Server provides encyclopedia coordination services by:

• Processing requests from the Coordination Client to read and update information about the encyclopedia and its users.
• Processing requests from other Clients to validate user passwords, determine user access to encyclopedias, and locate encyclopedias in the network.

Encyclopedia Server

Provides the encyclopedia functionality, including:

• Managing the users and user group access to models and subsets
• Managing the models and subsets

CSE Encyclopedia Server

Component services that are a collection of processes and utilities that implement the following functionality through processes stay in memory between service requests:

• The Lock process maintains access integrity on models, subsets, and encyclopedias.
• The ID Allocation process allocates and manages unique ID assignments for the system. For example, object IDs, model IDs, checkout IDs, and subset IDs.
• The User and Group actions manage user and group information in the encyclopedia database. This information also includes user membership in groups and user and group access to models.
• The Model and Subset actions manage the model and subset information that is stored in the encyclopedia database.
• The Version Control actions manage features such as migration, adoption, and model compare.

Encyclopedia Server Utility

Provides the encyclopedia functionality for on-demand tasks such as model and subset upload and download.

Construction Server

Manages the requests from the Construction Client. Together, they provide the capability to generate standard remote files, also known as implementation packages, for cooperative and non-cooperative applications and proxies.

Note: For more information about the server processes and utilities, see Client Server Encyclopedia Administration Guide.

The CA Gen environment imposes requirements on the encyclopedia database you be aware of when creating and preparing the database for the CSE to use. For more information, see the sections Create Oracle CSE Database and Create Microsoft SQL Server CSE Database.

For a list of valid DBMSs for the CSE, more information, or if you have any questions, contact Technical Support or your Account Representative. Refer to the CA Gen Technical Requirements at CA Support Online website at http://ca.com/support for the current software requirements.
