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.
