Goal
Often the questions of the limitations imposed by the Oracle database arise.
The Oracle database imposes some limits and one can find these limits in the Oracle documentation
for the specific release, book Oracle Database® Reference Appendix A Database Limits.
Refer also to
<Note 336186.1> - Database Limits
However, often the Oracle database is additionally restricted by some OS level restrictions, which
applies also to the Oracle software, since it generally operates at the next level and uses OS APIs to
complete operations, such as disk and memory management. The purpose of this document is to discuss
the memory limitations imposed by the 32-bit architectures
