Set Up Your Initial Configuration
This chapter uses a workbook approach to help you define your initial
configuration. The configuration worksheet lists each parameter needed for
initialization. The default value for the parameter is displayed in bold type
nextto the parameter name. Additional lines are provided for you to record
your parameter values where they differ from the default. Where appro-
priate, the worksheet includes calculation workspace.
In the pages that follow, eachtbconfig. std parameter group is defined in
detail,along with guidelines and instruction to help you choose a value that
is appropriate for your environment. The topics are organized according to
the layout of the tbconfig.std file.
Beforeyou begin, decide on your immediate use for OnLine. Do you plan to
useOnLine in a learning environment for a short time, or do you plan to use
OnLine in a production environment right away?
If you plan to experiment with OnLine as part of learning the product, you
canuse the default configuration parameters wherever they are provided. If
your goal is to initialize OnLine for a production environment right away,
carefully consider the effect of each parameter within your application
environment.
Referto page 1-23 for an explanation of how this decision (default or custom
configuration) affects the size of the root dbspace.
