Database Configuration 67
If you deploy an external database on a dedicated database server,
increased latency in the fulfillment of database requests may occur as a
result of network overhead.
Configuring Oracle External Databases
EMS uses JDBC database connection and interface drivers to
communicate with external databases. JDBC drivers are available from
the external database vendor. Usually, JDBC drivers are either bundled as
a part of the product or made available from a support web site.
EMS allows you to deploy either Oracle or MySQL external databases
in your network.
To use Oracle external databases with EMS:
1 Install the Oracle database according to the installation instructions
provided by the vendor.
2 To make sure that EMS can find the correct libraries to load when
connecting to the external database, download the JDBC drivers and
place them in the following folder on your EMS server:
<jre_home>/jre/lib/ext
where <jre_home> is the installation location of the JRE (Java Runtime
Environment) being used to run EMS. For more information on the
correct JRE version to use, see
Platform and Operating System
Requirements on page 43 .
3 Using the standard Oracle administrative tools, create a new, blank
database.
Do not configure the external database tables and schemas. When EMS
detects a blank database, EMS will automatically create all of the
necessary tables and configure them according to your customized
needs.
4 Using the standard Oracle administrative tools, configure a user account
on the database for use by the EMS server.
For more information on database users, see Multiple User Access for
External Databases on page 74 .
5 Since the default database used is Instant DB, you need to first comment
each line of the
Instant DB section by adding a pound sign (#) before
each variable of the server.properties file.
For example:
