On Windows, the INFORMIXSQLHOSTS environment variable is used only if
you want to capture the connectivity settings stored in the registry of another
computer.
If the ONCONFIG environment variable is not set, the utility creates one from a
combination of whatever parameter settings you provide in the configuration file
and onconfig.std. The file name format of the autogenerated ONCONFIG file is
onconfig.server_name.
Database Server Aliases
With the ifxdeploy.conf file, you can set up multiple database server aliases that
are equivalent to setting the DBSERVERALIASES configuration parameter in the
onconfig file. The ″ALIAS″ section of the file consists of fields in which you can
provide the SQLHOSTS connection information for each alias. The ″ALIAS″ setting
can expedite your deployment if you plan to use database server aliases because
you enter the connection information as part of the configuration file setup and do
not need to configure SQLHOSTS information separately.
Creating a Snapshot for Deployment
Create a snapshot of IBM Informix Dynamic Server that you can use with the
deployment utility to place pre-configured instances on multiple computers.
Before you create a snapshot, you must meet the following prerequisites:
v Windows administrator privileges on the computer.
v Sufficient disk space to save the snapshot in a file. If space is limited, you might
want to store the snapshot in a compressed file.
To create a snapshot, complete the following steps on the computer where you
installed the IDS instance:
1. Shut down the instance in a consistent state with onmode -kuy.
2. Create a snapshot of the following items:
v IDS installation directory
Tip: Ensure you include the IDSFILES.txt file, which is in the installation
directory. That file is required if you want to use the deployment utility to
remove the snapshot from the target computer after you deploy it.
v Configuration settings
v Optional: Data spaces associated with the instance
Tip: Store the components of the snapshot in a compressed file if you want
to save space. If you compress the snapshot with Gzip tar on UNIX or
Linux
®
or into a zip file on Windows, the utility can be automatically
decompressed by the deployment utility.
3. Optional: After you create the snapshot, you can restart the instance.
Deploying a Snapshot with the Deployment Utility
Deploy a snapshot of an instance by using the ifxdeploy command on the target
computer.
Before you deploy a snapshot, you must meet the following prerequisites:
v Windows administrator privileges on the target computer.
