Using Event Alarms to Monitor Disabling I/O Errors

When a dbspace incurs a disabling I/O error, the database server passes the following values as parameters to your event-alarm executable file.

Parameter

Value

Severity

4 (Emergency)

Class

5

Class message

Dbspace is disabled: 'dbspace-name'

Specific message

Chunk {chunk-number} is being taken OFFLINE.

If you want the database server to use event alarms to notify you about disabling I/O errors, write a script that the database server executes when it detects a disabling I/O error. For information about how to set up this executable file that you write, see the appendix on event alarms and the chapter on configuration parameters in the IBM Informix Administrator's Reference.
