Canister Server

A Canister Server is used for storing captured hits for active and completed sessions.

As a visitor explores your site, hit after hit is captured and added to visitor's session stored in the Short Term Canister through the Canister Server. When the session has completed, the Canister Server moves the session to the Long Term Canister.

When an instance of this server is created, an instance of the Canister Search Server is automatically created. The Portal needs to be aware of the Search Server hosted by the Canister to query for retrieval of sessions from the Canister.

Performance of the Discover system may be improved by adding a new Canister Server or changing properties in your current server.

Note: All Canisters listed as Active in the Portal Management page must be receiving data. If a single Canister is unavailable due to network issues or other reasons, scorecards, dashboards, and other reports are not updated until the problem is corrected. When the problem is corrected, any spooled data must be collected, aggregated, and stored in the database before reports are updated with the latest data.

In a typical installation, the machine hosting the Canister Server may also include a Canister Search Server.

See Canister Search Server.

The following fields apply to the Canister Server configuration:

Field: Value
Active: When set to Yes, this value enables the data collector to retrieve data from the specified server. Set it to No to make the server definition inactive so the data collector does not retrieve data from the specified server. This field is displayed on the Unica Discover Server Page.
Note: Reporting Data from inactive Canisters is still trimmed by the Data Collector based on the date. To preserve reporting data from Canisters which are now inactive, you must archive it to a separate location.
Display Name: The name you want displayed under the Server heading on the Unica Discover Server Configuration page.
Host Name: Enter the actual host name or IP address of the computer hosting the Unica Discover datastore. This computer collects statistics, report data, and search.
Note: The entered host name cannot resolve to the host name, IP address, or full qualified domain name of another active or inactive Canister Server.
Port: The port number for the ODBC connection made to the Unica Discover datastore.
Note: This setting is not used. The port number used is fixed as 5597.
User Name: The user name required to access the c-tree server.
Password: The password required to access the c-tree server.
Note: Changing the default password for this server is not supported in this version.
