LauncherLog

In the [Launcher] section of the dtx.ini file, you can specify the settings for a Launcher log file. See Trace and Log Files Naming Conventions for the specific naming conventions.

The LauncherLog file is not created by default. To ensure that a log file is created, you must remove the semicolon from the beginning of the designated line of text in the dtx.ini file. For example, the following line entry has had the semicolon removed and will create a file that contains error, warning, startup, and configuration information, and will be created in the product installation directory by default.


LauncherLog=ewsc

The default syntax is:


LauncherLog=[E][W][S][C]

Each option is described in the following table.

Option
Description
E
Logs map errors
W
Logs map warnings
S
Logs Launcher startup statistics
C
Logs configuration information

Regardless of the options you choose to log, the debug log (.txt) file (see Trace and Log Files Naming Conventions for the specific naming conventions) will contain header information that is similar to the following example:

Startup option

If you specify s for startup, you will see an entry on whether the startup of the Launcher was successful. If successful, something similar to the following entry is displayed:


*** STARTUP:
Status:               Successful
Time:               Thu Nov 21 10:53:11 2002

If not successful, it might pinpoint where the startup problem is:


*** STARTUP:
Status:               Failure
Time:               Thu Nov 21 18:49:58 2002
Errors:               No systems to run

Error option

If you specify e, the file lists all maps that have an error status after being run:
