Setting Up SAPDBA Screen Handling (SAP Library - SAP Database Guide: Informix (BC-DB-INF-DBA))

Setting Up SAPDBA Screen Handling

If your operating system is NT, screen handling is completely automated.

If your operating system is UNIX, follow this procedure to make sure SAPDBA can correctly produce screen displays on your terminal.

Procedure

Set the terminal type using the environment variable TERM .

Note

For more information on how to set environment variables, see Setting Up SAPDBA Environment Variables.

If your terminal has previously been used with the Informix database, the terminal type is probably already set. If it is not (or if the SAPDBA display is erratic), you must make sure that the environment variable TERM is set properly set. The most common values are:

- xterm for the X Window program

- hp for the hpterm program

- vt100 is a generic value that enables most terminals to work with SAPDBA

If none of these values produce a reliable display, you should consult the documentation supplied with your terminal.

Set the display size using the environment variables COLUMNS and LINES .

In most cases you do not need to adjust the display size because SAPDBA can automatically detect the size of your display window during start-up and generate the correct size of screen display. If for some reason SAPDBA cannot detect your window or screen size automatically, SAPDBA sets a default display of 24 lines by 80 columns.

You can explicitly set the environment variables. This can be useful if SAPDBA has set a default display for your session and you would like to use a larger display. Make sure that the minimum values you set are 80 for COLUMNS and 24 for LINES and remember to restart SAPDBA.

Caution

Do not change the size of your screen display while SAPDBA is running because the results are unpredictable. SAPDBA sets the size during start-up and adjusts its displays accordingly.
