5 Startup 2. Startup The following connection window appears each time an instance of this utility is started. Server Connection Server Name/Port Number - Using this combo box you can select if you are going to specify the c-treeace Server Name or its TCP/IP port number in the underlying text box. This example shows the Server Name "FAIRCOMS". Machine Name/IP Address - Use this text box to specify the IP address or the machine name where the c-treeace Server is running. If your c-treeace Server is running on your local machine, using the "localhost" machine name will provide better performance. User Options User Name - Specify the user name you want to use to make the connection to the c-treeace Server. Password - Use this text box to enter the user's password. Note the default "User Name" and "User Password" are both "ADMIN" and the Password is case sensitive. When you're done press OK to establish the connection. If you press Cancel the tool will not be connected to the c-treeace Server. All Rights Reserved 5

Stop Server Dialog This dialog box is accessed from the Server Menu and Toolbar Stop Server icon and allows you to stop the c-treeace Server. To stop the server, set the delay time and then click OK. Cancel will abandon the dialog with no action taken. 14. Quiesce the Server Temporarily suspends operation of the c-treeace Server for specific administrative actions. Periodically, there may be times where an administrator may wish to open a maintenance window for more detailed and comprehensive data management. Stopping the c-treeace Server can be a challenging task in a high availability setting with large numbers of users. Coordinating this down time can be a frustrating experience. What is needed is a functionality to halt c-tree Server operations cleanly, while allowing user applications to remain connected. This function is frequently referred to as quiesce. The quiesce functionality allows an administrator to suspend, quiet or quiesce, c-treeace operations and later re-enable them. This allows c-treeace administrators to perform maintenance or other on-demand activities without having to stop an application. Users are temporarily held back from operations. Files can be readily accessed for backup, especially useful for hardware-based disk snapshot utilities. All Rights Reserved 23

24 Quiesce the Server To use this powerful feature, simply set the "Pending transaction not committed" time and then press the Quiesce button. Note that any transactions that have not committed within the setting specified here will be aborted, so set this value wisely. Note, it is also important to understand that any applications being serviced by the c-treeace Server during a quiescent state (e.g., quiet state) will be suspended. Therefore be careful not to put the Server in this state and then induce any unnecessary delays. All Rights Reserved 24
