OMNM 6.5.3 Installation Guide 15
Verifying System Requirements
System requirements depend on how you use the application and the operational environment.
Your specific network and devices may require something different from the recommendations for
typical installations.
Base the minimum configuration of any system on its expected peak load. Optimally, your
installation should spend 95% (or more) of its time idle and 5% of its time trying to keep pace with
the resource demands.
Refer to the
OpenManage Network Manager User Guide for sizing guidelines.
NOTE:
System requirements ( software/hardware) vary depending on how you plan to use the OMNM
application. Use the information in this section only as a guide.
Software Requirements
You must have the following software installed and operational before installing or upgrading the
OpenManage Network Manager (OMNM) application. Refer to the product
Release Notes for any
last minute changes that occurred after this guide was released.

Databases Unless you have purchased an HA or Custom package, the standard OMNM software
is a single-server installation and the MySQL database installs automatically. If you
are doing an HA or distributed installation where you provide the database, make sure
that it is one of these:
• MySQL 5.7.19
• Oracle 9i (9.2.0.5) up to Oracle 12c R1 (12.1.0.2.0)
Note: Oracle 12c does not support the multitenant feature. Oracle databases are
recommended for distributed, clustered, or highly available installations.
• Oracle 10g RAC or later for High Availability installations
• Oracle database requires that the ORACLE_HOME environment variable be set
to the local Oracle installation’s home directory where the bin and jdbc directories
reside
