Viewing Database Engines

---

Pervasive Control Center (PCC) provides a unique view of available database engines, databases, and actual data. This section explains how to view these objects in PCC.

To view registered database engines

1. Open PCC:
   Choose Start4Programs4Pervasive.SQL V84Control Center.
2. You can view the database engines that you have registered in PCC by double-clicking Pervasive.SQL Engines in the left-hand pane (the Namespace) of PCC.

   If you want to add more database engines to the list, follow the instructions provided in Registering or Removing a Server .

   By right-clicking on a particular database engine, you can choose to view its properties, refresh its database list, or delete it.

Note
If you have engines registered that are not running, you may encounter delays in PCC as it periodically attempts to contact these engines. To eliminate the delay, unregister the "dead" engines. You can minimize the delay by performing the following procedure:

In PCC, right-click Pervasive.SQL Engines and choose Properties. Set Poll interval (seconds) to 999. Click OK.

Interpreting Engine Status Icons

Computer names are listed in the namespace tree under the Pervasive.SQL Engines node. An icon indicating the state of the Pervasive.SQL engine on that computer accompanies each engine name. The possible states of the database engine are outlined in the following table.

Note
When PCC is next started, engines remain in the Namespace even if the engines are not running. Engines that are not running are listed in the namespace with an appropriate icon indicating the engine is not running.
