This section describes environment variables that are used and the directories and files that are created at installation. Depending on the type of installation (Platform or Execution Container), there may be less directories and files than listed here.
Environment Variables
The following environment variables are set in This environment variable specifies where the JDK is installed. Example value: This environment variable specifies the container name. Example value: This environment variable specifies the container type. It is typically not changed. Example value: This property specifies a URL, which contains the IP address or hostname of the Platform Container and the Web Interface port. When you have entered a hostname and failover occurs, the hostname is retrieved from the DNS enabling reconnection. If you have entered a static IP address as the value of this property reconnection issues may occur if the IP address changes. The port must be unique for each Example value: This is the directory where the Platform Container or Execution Container container is installed. Example value: MZ_HOME/bin/mzsh after installation.Variable Description JAVA_HOME /opt/jdk/jdk-17.0.2MZ_CONTAINER container1MZ_CONTAINER_TYPE platformMZ_PLATFORM 
system.http://localhost:9000MZ_HOME /opt/mz/container1
You can view and set these environment variables by using the mzsh command topo env. For further information, see /wiki/spaces/MD82/pages/3786575. You may also override these properties in the shell.
MZ_HOME Directory Structure
MZ_HOME refers to the installation path of the Platform Container, Execution Container. You must set MZ_HOME as an environment variable on your system. For further information about how to set this path, see the /wiki/spaces/MD82/pages/3768324.
The directories that are created in MZ_HOME after a default installation of a Platform Container are described below. When you install an Execution Container, a subset of these directories are created.
The owner of the files and directories in MZ_HOME is referred to as mzadmin throughout this document.

| MZ_HOME/3pp | This directory is used for storing files required by third-party software, e g database drivers. | ||||||||||
| MZ_HOME/backup | This directory contains the backup files produced when performing a System Backup task or a System Import, see the /wiki/spaces/MD82/pages/3768690 for further information about these operations. The directory will be created when the first backup is made. | ||||||||||
| MZ_HOME/bin | This directory contains the commandline tool, mzsh. You can use the the command line tool to interact with Use the command line tool to start different parts of the system, such as the Platform or an Execution Context. These entities are running in their own Java Virtual Machines and are referred to as Pico processes. Every pico process has its own definition in STR. For further information about STR, see System Topology Registry For further information about the command line tool, see /wiki/spaces/MD82/pages/3778935. | ||||||||||
| MZ_HOME/codeserver | This directory contains all the mzp packages in your installation, as well as any Jar files generated from your APL and Ultra configurations. Note! The contents of this directory should not be modified. | ||||||||||

| MZ_HOME/lib | This directory contains the code that is necessary for the non-pico started servers and that is not loaded from the code server, as well as third party code. The pico-started servers, e g the Desktop and the ECs, executable code will never be fetched from this directory during runtime. The code is instead fetched from the pico cache. The exceptions are the Code Server and pico-start utility, | ||||||||||
