Several instances of IDS 7.3X

Hi !!! I need to know how I can set up several instances of the Informix Dynamic Server 7.3x in the configuration files "sqlhosts", "onconfig" and the ".profile" (environment file). Now I have only one instance but I want to add one more...please I'd like to see an example of several instances configuration. Thanks. Alejandro Cabrera acabrera@topmail.com.ar

This is actually quite simple. You just create a separate ONCONFIG file for each (name then onconfig.<servername> for example). Make the following parameters different in each file: SERVERNUM DBSERVERNAME DBSERVERALIASESROOTDBS (different either in path or offset - careful!) You can share one sqlhosts file or use different ones depending on if the instances need to be able to see each others' data. If different use SQLHOSTS or INFORMIXSQLHOSTS variable to locate the right one. Place entries for each DBSERVERNAME and DBSERVERALIAS for all or some of the instances in the file. Servers on the same physical host must use different service/port ids/numbers. In the users .profile set INFORMIXSERVER to the servername of his default server and provide scripts to set the others when run as a 'dot' script: . informix.server1 . informix.server2 SERIOUSLY consider using my onspaces wrapper, aspace, to manage disks so you do not have the engines stepping on each others disks.
