7.3 Upgrading an Existing 3.0.x Installation

This section describes how to upgrade an existing installation of MySQL Enterprise Monitor 3.0.x.

Each release of MySQL Enterprise Monitor contains a full installation package for a clean installation, and an upgrade installation package to upgrade existing installations to the latest version. Each installer, full or update, with the exception of FreeBSD, also contains a compatible JVM. If you are installing on FreeBSD, you must download and install a compatible JVM.

Upgrading the MySQL Enterprise Service Manager

The MySQL Enterprise Service Manager upgrade installer performs the following tasks:

  • Stops the MySQL Enterprise Service Manager service.

  • Stops the Tomcat service.

  • Stops the MySQL Enterprise Monitor MySQL repository.

  • Checks to ensure the services have stopped.

  • Backs up the existing installation and repository.

    The backup enables you to rollback to the preceding version if a problem occurred with the upgrade.

  • Updates the installation with the new MySQL Enterprise Service Manager version and installs the bundled JVM.

Upgrading the MySQL Enterprise Monitor Agent

The MySQL Enterprise Monitor Agent upgrade installer performs the following tasks:

  • Stops the running agent.

  • Backs up the existing installation.

    The backup enables you to rollback to the preceding version if a problem occurred with the upgrade.

  • Updates the installation with the new MySQL Enterprise Monitor Agent version and installs the bundled JVM.
