Amount of space that databases require

The amount of additional disk space required for the database server data storage depends on the requirements of users, plus overhead and growth.

Every application that users run has different storage requirements. The following list suggests some of the steps that you can take to calculate the amount of disk space to allocate (beyond the root dbspace):
  • Decide how many databases and tables you must to store. Calculate the amount of space required for each one.
  • Calculate a growth rate for each table and assign some amount of disk space to each table to accommodate growth.
  • Decide which databases and tables you want to mirror.

For instructions about calculating the size of your tables, see your HCL Informix® Performance Guide.
