Check resource requirements
Before beginning an installation, be certain that sufficient system resources are available. The IUG for your platform contains comprehensive information about disk storage and memory requirements. Remember that these requirements are minimums, and that the resources required may actually be higher, depending on other configuration decisions you make. For example, more memory will be required if you specify a larger SGA.
In particular, make sure there is enough disk space available on the device where you place the Oracle software (typically called ORACLE_HOME ) to load all software and ancillary files.
