Capacity Planning

One of the most important factors to determine about your database is its overall size. In your planning, you will need to allocate space for system storage, temporary tablespace, log files, and other system files required by DB2, and space for Siebel data and indexes. If you allocate too little space for your system, performance will be affected and, in extreme cases, the system itself may be halted. If you allocate too much, you waste space.

The space needed by DB2 will vary primarily based on the total number and types of users supported. It is recommended that you consult the IBM DB2 technical documentation for more information on these requirements.

The space required for Siebel data and indexes will vary depending on what Siebel functionality you implement and the amount and nature of data supported. At a minimum, Siebel 7 requires that you size your DB2 database to between 1 and
1.5 GB.

The process for making accurate database size calculations is a complex one involving many variables. The following guidelines will assist you in the process:
