DataSpot Server Manager

The DataSpot Server Manager utility enables a data provider to manage the DataSpot query process. For example, session handling, viewing information on entered queries, and setting parameters for the DataSpot Search Server.

To open the DataSpot Server Manager:

Select the DataSpot Server Manager icon.

The DataSpot Server Manager window is displayed.

DataSpot Server Manager Window

The DataSpot Server Manager window provides a visual display of the status of all DataSpot queries currently being handled by the DataSpot Search Server.

Each line in the display area provides information on the status of a single query. You can perform the following functions in the DataSpot Server Manager window:

•	Double-click a query to end the selected query.

•	Double-click a session to end the selected session.

•	Double-click a Web View to end all sessions related to that Web View.

•	Start or stop the DataSpot Search Server.

•	Open the DataSpot Server Manager Parameters window.

DataSpot Server Manager Window Parameters

The following is a description of the fields and buttons in the DataSpot Server Manager window:

Web View: Displays the name of the Web View.

Session: Displays the session ID (number).  By default, a session is opened the first time an end-user enters a query. It ends when the timeout period is met, which means that the end-user did not respond for the period defined as the session timeout. A session also ends (and restarts a new session) when the first page is displayed on the screen and the end-user clicks the Reload button of the Web browser.

The data provider can specify that every query opens a new session by modifying the template file to do this. Refer to the DataSpot Template Mechanism Reference & Design Guide for more details.

Longer sessions enable the end-user to return to any page encountered on the way and continue the search in a different direction than the one that was previously selected. For example, if a query was invoked to locate wineries in the Spokane area, then a specific winery was selected, and then a new query was invoked to search for wines suitable for dessert, the end-user can go back to the initial Spokane wineries answer list (using the Back button of the Web browser). The end-user can then click the More answers button or select another winery from the Spokane wineries answer list.

Note: Longer sessions consume more system resources and therefore will affect performance.

Query ID: Displays the query ID. The query ID is a number made up of two sections separated by a slash (/). The first section is the number of the query within the session, the second section is an internal ID number for the query.

Active: Displays + if the query is currently active, displays - if the query is not currently active. If the query is active, also displays one of the following:

•	(w) - Search Server is currently waiting for user response.

•	(1) - (5) - Indicates the aging level of the query (five stages). See the Query Aging Level parameters on the following page for further information.

Done: Displays + if all relevant answers to the query have been found in the Web View. Displays - if answers still remain to be located for the query.

Steps:Answers: Displays information regarding the answers that have already been located for the query. The Steps:Answers field displays numerical information in three sections, for example, 1089(59)/8.

The first section is an internal code indicating the size of the area in the Web View that has been already searched. The second section indicates the number of steps that the query has already processed. The third section indicates the number of answers that have already been located.

Query: Displays the text of the query entered.

Displayed Queries: Click the All radio button to display all the queries in the DataSpot Server Manager window, or click the Active radio button to only display the queries which are currently active (not including queries currently waiting for user response).

Parameters button: Opens the DataSpot Server Manager Parameters window in which you can set parameters for the DataSpot Search Server.

Stop Service button: Closes all sessions and stops the DataSpot Search Server. This button toggles to display Start Service. Click the Start Service button to restart the DataSpot Search Server.

Status Bar: Displays system messages.


Setting DataSpot Search Server Parameters

The DataSpot Server Manager enables you to set parameters for the DataSpot Search Server. For example, you can specify the maximum query response time, session timeout and minimum answers in the response.

To define DataSpot Server Manager Parameters:

1.	In the DataSpot Server Manager window, click the Parameters button. The DataSpot Server Manager Parameters window is displayed.

Note: Not all of the DataSpot Server parameters are visible in the window at one time. Use the scroll bar to scroll up or down through the parameters in the list.

2.	Double-click the parameter that you want to define. A parameter definition window is displayed. The text in the parameter definition window relates to the selected parameter.

3.	Enter a value for the selected parameter and click OK. The DataSpot Server Manager Parameters window is redisplayed containing the newly defined parameter value.

4.	Continue to define parameters in this way as required, then click Close to close the DataSpot Server Manager Parameters window. The DataSpot Server Manager window is redisplayed.

5.	In the DataSpot Server Manager window, click the Stop Service button, and then click the Start Service button. This step must be performed in order for the newly defined parameters to take effect.


DataSpot Server Manager Parameters Window

The DataSpot Server Manager Parameters window contains two sets of parameters for the DataSpot Search Server:

ISAPI/NSAPI Extension Parameters

DataSpot Search Server Parameters


ISAPI/NSAPI Extension Parameters

Log level: Enter the ISAPI/NSAPI log level.

Log file name: Enter the ISAPI/NSAPI log file name.

Maximum query response time (in seconds): Define the maximum time period (in seconds) that can elapse before answers to a query are displayed. If no answers are located within this time limit, either the message No answers located yet is displayed, or, if there are already answers displayed on the screen, the screen display is refreshed.


DataSpot Search Server Parameters

Session timeout (in seconds): Define the time period (in seconds) after which a session will end if no user response is detected.

Minimum answers in response: Define the minimum number of answers to be displayed in a query response. This parameter is related to the Maximum query response time parameter. Answers will either be displayed after the minimum number of answers have been located, or at the end of the defined response time, depending on which occurs first.

Background query processing threshold (for answers): Define the number of answers that the DataSpot Search Server should continue to locate while waiting for end-user input to continue the search.

Query aging level 1 to 5 (in seconds): Define the time period (in seconds) for each stage of the query aging process. The query aging levels represent the intensity of the work performed by the Search Server in locating answers to a query. That is, in Level 1, the Search Server works most intensively to locate answers, and as the query progresses through the aging levels to Level 5, the level of work intensity lessens.

Set DataSpot Server Debug Level button: Define the DataSpot server debug level.
