Problem(Abstract)

IBM® Informix® Dynamic Server™ (IDS): After setting up a HDR pair environment, there is sometimes confusion on how to add logical logs. 
This document provides you with a correct procedure on how to accomplish this task.

Resolving the problem

INTRODUCTION

This guide outlines the supported method of adding logical logs in a HDR pair in the IDS environment, where a new log is initially added to the primary and then replicated to the secondary server.

STEPS 

  1. This step adds log(s) in a HDR pair environment. Use onparams" command to add the desired number of logs on the primary server, for example: 

    $ onparams -a -d logspace 

  2. The onparams operation is automatically replicated on the secondary database server. 

  3. The action of adding logs can be confirmed by checking the online.log messages and a logical log listing (by means of onstat -l" ). 
    The command onstat -l" will display the newly added log(s) with the flag 'A'. 
    The logs are immediately available for use. 

  4. A level-0 archive of the rootdbs and the dbspace containing the newly added log(s) is recommended.
