NAME

tkdm - Multi-host data manager written in Perl for UnixODBC.pm

DESCRIPTION

Tkdm is a personal, multi-host ODBC data manager that uses Perl/Tk for its user interface, and the UnixODBC BridgeServer.pm module for network communication. Refer to the UnixODBC::BridgeServer man page and the README file of the UnixODBC source code package for details of how to configure multi-host ODBC communication.

OPTIONS

Tkdm recognizes the following command line options.

--bgcolor

Set the window background color.

--debug

Print debugging messages on the terminal.

--displayfont font

Set the font used to display widget text.

--help

Display the command line options on the terminal and exit.

--monofont font

Set the monospaced font used to display columnar data.

--relief style

Set the widget relief style. The "style" paramater may be one of: "raised," "sunken," "flat," "ridge," "solid," "groove," or "none."

--selectedfont font

Set the font used to highlight selected widgets.

Usage

DSN Window

The left-hand window of tkdm displays the network hosts and data sources that are available to the UnixODBC bridge server, which were configured when the UnixODBC libraries were installed. If tkdm cannot connect to a host, it will display that host's icon X-ed out.

Clicking on one of the data source labels will cause tkdm to request the login user name and password for that data source. Once login is successful, you can click on one of the tables in the data source's database, and tkdm will draw a query form for that table in the right-hand window. Refer to the next section.

Table Query Window

The right hand window presents the controls for selecting and inserting data, and executing other types of SQL text queries.

The three buttons in the upper left-hand corner of the window, described here from left to right, perform the following functions:

- Execute a SELECT query, modified using the field selectors and predicate inputs in the checkboxes and text entry boxes.

- Execute an INSERT query, using the data entered in the text entry boxes.

- Open a dialog box where the user can enter the text of a SQL query.

Once the query is submitted, tkdm will display the number of rows and columns in the result set, and, if the query returns data in the result set, tkdm will display the data in tabular form in the window.

CONFIGURATION

You will need to create a file named ".odbclogins" in your $HOME directory, which contains the information for logging into systems on the network.

Each line in the .odbclogins file provides the login information for one host, including the local system. The format of each line is:

<hostname>::<username>::<password>

To access the data sources on the hosts named "accounting," "sales," and "warehouse," for example, the .odbclogins file would look like this:

accounting::mylogin::mypassword
sales::mylogin::mypassword
warehouse::mylogin::mypassword

Substitute the actual login name and password for each system for "mylogin" and "mypassword."

The format of the .odbclogins file is similar to the odbclogins file used by the ODBC server. There is a sample odbclogins file in the bridge directory of the source code directory.

Caution - The .odbclogins file can present a signifiant security risk if other users can read your login data. To prevent this, remove the group and other read permissions for the file, by using the command:

# chmod 0600 .odbclogins
