IBM GC23-7753-05 manual Instance Configuration Wizard, Planning Role Separation

Instance Configuration Wizard

The Instance Configuration Wizard is an installation option that automatically creates a database server configuration file customized to your system environment.

You can use the Instance Configuration Wizard on a Windows computer when you install using a custom setup in GUI mode. In the installation application, the checkboxes for Initialize Server and for enabling a custom configuration file must be selected to invoke the wizard.

Note: When the Initialize Server checkbox is selected, the installation will delete any existing IDS data on the host computer.

The wizard is a utility that ensures your settings are valid, and it calculates values for other server configuration parameters based on your settings. The configuration information is stored in the ONCONFIG file so that when you start the instance after the product is installed, the instance runs with settings appropriate for your environment.

If you use this configuration utility, the installation’s settings cannot be recorded in a response file for silent installation.

The Instance Configuration Wizard prompts for the following configuration settings and system information:

vserver name

vserver number

vrootsize: the size of the root dbspace (in megabytes)

vnumber of central processing units (CPUs): a CPU is equivalent to a single execution unit

vmemory: system RAM dedicated to the server instance being created (in megabytes)

vnumber of online transaction clients (applications used for modifying the state of databases)

vnumber of query clients (applications used for returning result sets for decision support; typically require more overhead than clients used for transaction processing)

The number of ONCONFIG file parameters set by this wizard varies, depending on your hardware and database system needs.

If the Instance Configuration Wizard encounters a problem while checking the entered settings, the configuration file is created with standard, workable configuration parameters and a message about this is displayed.
