Monitoring the database server for disabling I/O errors in the chapter on managing disk space in the IBM Informix: Administrator's Guide

ONDBSPACEDOWN defines the action that the database server will take when any disabling event occurs on a noncritical dbspace. The following values are valid for this parameter.

Value

Description

0

Continue. Causes the database server to mark a noncritical dbspace down and continue whenever a disabling I/O error occurs on it.

1

Abort. Causes the database server to fail without allowing a checkpoint to occur whenever a disabling I/O error occurs on any dbspace. Critical dbspaces run only in this mode.

2

Wait. Causes the database server to hang all updating threads as soon as the next checkpoint request occurs after a disabling I/O occurs on a noncritical dbspace.

To modify the ONDBSPACEDOWN parameter dynamically, use the onutil SET command. Example:

%onutil
1>    SET ONDBSPACEDOWN 2;
