Re: Creation of another IDS instance

In Response To: Creation of another IDS instance (MUKESH TANUKU)


assuming you want to create the second instance with the same version

of Informix:

- use the same directory where informix server is installed, i.e.

$INFORMIXDIR is the same.

- choose a different SERVERNUM (server number),

- choose a different server name (and set $INFORMIXSERVER


- if desired: choose different name(s) for DBSERVERALIASES,

- create a different onconfig file in $INFORMIXDIR/etc (and set

$ONCONFIG accordingly),

( my onconfig files usually are named "onconfig.${INFORMIXSERVER}" )

- create separate shell scripts for each server instance to set the

environment for each instance:

- $INFORMIXDIR (is the same)

- $INFORMIXSERVER (is different)

- $ONCONFIG (is different)

- $INFORMIXSQLHOSTS (can be the same, but will be different if you

choose to have separate sqlhosts files (see below))

- $PATH and the library path environment variable, $CLASSPATH if

needed, will all be the same.

- you best create a new directory where you can place the chunks for

the new dbspaces of the new instance,

- best practice: create symbolic links to the chunk files, and then

use the symbolic links when creating dbspaces and chunks

and as value for ROOTPATH in the onconfig file.

- choose a new file name (or better a new directory location) for the

message and console log files.

- if using ON-Bar choose new file names (or better directory location)

for the BAR activity and BAR debug log files,

- if using ON-Bar you may want to think about creating new (i.e.

different) storage pools for the new instance.

- you may want to think about creating a separate alarm program shell

script, especially if you want to handle

logical log file backups differently. Usually this is in


- in the new onconfig file:


ROOTPATH (and MIRRORPATH, if applicable) to the new values.

- set MSGPATH and CONSOLE according to the choosen path names of the

message/console log files,

- if using ON-Bar for backup and restore: set BAR_ACT_LOG and

BAR_DEBUG_LOG to the chosen new file/path names,

- if using ON-Bar and you chose to create new storage pools for the

new instance: set parameters ISM_DATA_POOL and ISM_LOG_POOL


- if you chose to create a new alarm program shell script: set

parameter ALARMPROGRAM accordimgly,

- set parameter FULL_DISK_INIT to 1 ( in the new onconfig file only

! )

- create new entries in the sqlhosts file:

- you can use the same sqlhosts file for multiple server instances.

If you want to use separate sqlhosts files,

then you create them and need to set $INFORMIXSQLHOSTS accordingly

for each instance's environment.

- at minimum add one entry for the new $INFORMIXSERVER name,

- if desired add entries for DBSERVERALIASES names,

- create new service names in /etc/services using different port


Use these new service names for the new sqlhosts entries.

- you CHECK AGAIN, that the ROOTPATH values in the different onconfig

files are:

- really different,

- and the symbolic links (that you hopefully use) point to different



- do not cause an overlap (especially if using raw devices): look


- set the environment for the new server (using the newly created

shell script).

- do "onstat -c | egrep ROOT" to check that you get the new and

correct environment.

- you should now be ready to do "oninit -i" ... and when it asks your

confirmation for the disk initialization:

again make sure that you are working with the correct environment

for the new instance.

(The seeting of FULL_DISK_INIT to value 0 in the old instance

environment hopefully prevents

you from obliterating the old instances data.)

I hope I did not forget anything important.

Others may correct me in case I'm wrong. :-)
