Critical Decisions

While most decisions made during installation can be changed at a later time, some decisions are either very difficult or impossible to change, so it is important that you make these decisions correctly at the time of installation. They include:

  • Creation of a starter database

  • Location of Oracle software (ORACLE_HOME )

  • Directory structure for Oracle datafiles

  • Language to be used

  • Database blocksize

  • Number, size, and location of online log files

  • Maximum number of datafiles to be allowed

We describe each of these decisions in the following sections.
