LOG.SYS

Error Logging Device Driver

The OS/2 Logging Facility device driver enables in conjunction with LOGDAEM.EXE the logging of system error messages and some application error messages.

DEVICE=C:\OS2\LOG.SYS <parameters>

Parameters

• /E:value

This sets up the log buffer size. Value can be in the range from 4 to 64.

Default = 8, This value is expressed in kB.

• /A:value

This is the size of the alarm buffer. Value can be in the range from 4 to 64.

Default = 8, This value is expressed in kB.

• /OFF

If set to OFF the driver is installed but the logging of error messages is turned off. You can turn it on again with the program SYSLOG.EXE.

Examples

To install the log driver with a log buffer size of 48 Kbytes and an alarm buffer of 16 kB, add this line to your config.sys file:

DEVICE=C:\OS2\LOG.SYS /E:48 /A:16

To install the log driver but turn it off after initialization use this line:

DEVICE=C:\OS2\LOG.SYS /OFF

NOTE

LOG.SYS has its limitations. It will not log an application error unless the application has been written to make use of LOG.SYS. Some routine system errors will not log either because OS/2 opens an error message box on screen to report these.
