3. Create a LANSA Client Environment

The LANSA Client environment is created by selecting the required options in the LANSA Client Administrator window.

Some options are language or host specific, and are selected from dialog boxes that are described separately. These are:

Configured Hosts

This box contains a list of the hosts configured for this environment. Initially it will be empty.

There must be at least one host, and there can be a maximum of 100 hosts defined for a single LANSA Client environment. When there are multiple hosts defined, the user chooses which host to connect to from a list displayed when LANSA Client starts.

To View the details of an existing host system:

To Add a new host system:

To Copy an existing host system:

To Change the details of an existing host system:

To Delete a host system:

Refer to 3.1 Specify the Host and Related Options for details of the Host Configuration Details dialog box.

Display "Changed Host" Warning

For a query that is run against a different host a "different host" warning message will be shown. The warning message has a "do not show this again" option, so that LANSA Client will not keep showing the message.

Application Generation Support

Use the Application Generation option to turn on or off the application generation capabilities of LANSA Client.

Refer to Generate Applications in the LANSA Client User Guide if you would like to find out more about LANSA Client's application generation capabilities.

Enable LANSA Client Tracing

Turn this option on to enable LANSA Client tracing. The trace file is located in a folder called lansaclient under the TEMP folder, is named after the application running and has the extension .log.


<Drive>:\Users\<User Name>\Appdata\Local\Temp\lansaclient\lc32.log

<Drive>:\Users\<User Name>\Appdata\Local\Temp\lansaclient\lcrun32.log

<Drive>:\Users\<User Name>\Appdata\Local\Temp\lansaclient\lcsetup.log

Note that turning LANSA Client Tracing on will have an impact on performance. Only use this option when directed to do so by LANSA Support.


Press this button to open the LANSA Client Language Option dialog box.

For details about the options related to languages, refer to 3.2 Choose the Language and Font.

Query Location

Press this button to open the LANSA Client Query File Location dialog box.

For details about the settings related to default query location, refer to 3.3 Set Query File Location .

DateTime Result Format

If you save your Results to an Excel or dBase file, and if your data contains a date or time, you can specify whether you want the dates or times saved as text/numeric or in a date or time format as described in 3.4 Default DateTime Result Format.

The options selected can be overridden using the Date Time Formats command on the Format menu.

Default Data Format Type

Specify the default type of database to be created when outputting query results.

Within LANSA Client the output database filename and type may be specified for each query, which will override this default value.

Saving results

When the results of a query are saved, either the field's name, the field's description or the field's label will be included. These names are stored in the LANSA Repository on the host. As the label is limited to 15 characters, it is preferable to use it for column headings rather than the description, which can be up to 40 characters long.

Note: Some of the file formats to which you can save a query's results may cause the field name to be truncated. For example, the DBF format will only allow 10 character field names (i.e. column headings) and they must only consist of alphanumeric characters. LANSA Client will ensure that the names of all the fields within a file are unique.

Default Join Type

Specify the Join Type to be used as the default for all new joins in your query.

The Join Types available are:

Save the Environment

Press the Save button to save the changes you have made using the LANSA Client Administrator.

All the options you have selected for this LANSA Client environment are written to the LC32.LCX file which is saved in your LANSA Client folder.

Note: The Save button is only enabled if there are unsaved changes.

Exit from the LANSA Client Administrator

Select the Exit button. If you have modified the configuration and have not saved the changes, you will be prompted to do so.

Note: Close, then open LANSA Client to "pick up" the new defaults.
