Add the following environment variables into a login script for the user mzadmin, ensuring the variables are always used. The example values will be used later on in the installation parameters file install.xml.

VariableDescription

MZ_HOME

Example value: /opt/mz

This environment variable specifies where the software is to be installed.

Note!

The directory must exist and be empty prior to the installation.

Note!

You should use an absolute path instead of a symlink for the MZ_HOME directory to avoid any issue during installation or upgrade.

JAVA_HOME

Example value: /opt/jdk/jdk-17.0.2

This environment variable specifies where the JDK is installed. For example:

/opt/jdk-<interim.update.patch>

PATH

The search path must contain the following directories: $JAVA_HOME/bin:$MZ_HOME/bin

This environment variable specifies the search path.

Example - Setting Environment Variables

$ export MZ_HOME=/opt/mz
$ export JAVA_HOME=/opt/jdk/jdk-17.0.2
$ export PATH=$JAVA_HOME/bin:$MZ_HOME/bin:$PATH

Oracle Specific Environment Variables

These environment variables only apply when using an Oracle database. The variables below are set on the machine where Oracle is installed.

VariableDescription

ORACLE_HOME

Example value: /opt/oracle/product/12

This environment variable specifies where Oracle is installed.

ORACLE_SID

Example value: MZ

This environment variable specifies the Oracle SID to be used by the system.

Note!

The Oracle SID name cannot be longer than 8 characters.

ORACLE_DATA

Example value: /opt/oracle/databases/<data_directory>

The directory where the database will be stored. This directory must exist prior to installation.

Note!

In order for to function properly, the following Oracle file needs configuration:

$ORACLE_HOME/network/admin/listener.ora

For further information, see Appendix A - Oracle Home Settings.

Note!

The installation script only supports using Oracle SID. It does not support using the Oracle service name.
