Changes in MySQL Enterprise Monitor 3.3.5

Functionality Added or Changed

* The OpenSSL libraries used by the MySQL Enterprise Monitor
installers and MySQL Enterprise Monitor Aggregator have been
upgraded to 1.0.2l.

* The MySQL server, bundled with the MySQL Enterprise Service Manager,
has been upgraded to MySQL 5.7.19.

Important: Changes have been made to the prerequisites of MySQL
5.7.19.

- libnuma.so.1 must be present on Linux platforms. The MySQL
Enterprise Service Manager full and upgrade installers check for
the existence of this library.

- During a MySQL Enterprise Service Manager upgrade, the upgrade
installer runs the mysql_upgrade utility.

* The Tomcat server, bundled with the MySQL Enterprise Service
Manager, has been upgraded to 8.5.16.

* The bundled JRE was updated to 1.8.0_141 for both the Agent and
Service Manager.

Bugs Fixed

* On the Advisors page, filtering for specific advisors did not return
all the advisors filtered for. (Bug #26668301)

* On Linux, Unix, and Mac OS X platforms, the agent installer did not
check the installation directory to ensure it had the required
permissions to install MySQL Enterprise Monitor Agent in that
location.

As of this release, the installer checks the directory for the
appropriate permissions. If it does not have the rights to install
to that location, it returns the following error message:

There has been an error.
The current installation directory could not be accessed by non-root users.
Please select a different installation directory or change the permissions
to 755 for this directory.

(Bug #26551166)

* It was not possible to install the MySQL Enterprise Service Manager
on Solaris due to a missing file, libstlport.so.1. (Bug #26336679)

* Validation messages were not displayed on the Settings page after a
successful change was made.

* Sparkline graphs did not refresh dynamically.

* It was not possible to edit multiple advisors using the Edit
Selected button.

* Agent host names were not displayed in the list of agents on the
Advisors page, only the alphanumeric agent ID was displayed in
truncated form. This made it difficult to identify the agent.

As of this release, the agent is listed with the name of the host on
which it is installed, instead of the alphanumeric ID.

* Clicking on the Database Availability graph, on the Overview
dashboard, opened a blank page instead of the Events page.

* Under certain circumstances, such as filtering on many graphs on the
All Timeseries page, the resulting graphs were not correctly
populated with data. This was caused by the default value for the
maxHttpHeaderSize in the Tomcat configuration file, server.xml,
which is set too low for large quantities of data. The value is set
to 32K by default.

As of this release, the value of maxHttpHeaderSize is doubled, to
64K, and applied to both the SSL and non-SSL connector
configurations in server.xml.

If you are upgrading to this version from a previous version, you
must edit server.xml and add maxHttpHeaderSize="65536" to each of
the default connectors.

If you are performing a clean installation of MySQL Enterprise
Service Manager, you do not need to edit any files, the new values
are included by default.

* On Mac OS X platforms, the java_home_dir variable was not set
properly by the installer. As a result, the configuration report
contained the following error: ***unknown variable java_home_dir.

* On Linux, Unix, and Mac OS X platforms, the MySQL Enterprise Service
Manager upgrade installer could not upgrade the installation if the
installation directory contained files or directories created by a
different user, or a user with permissions which differed from those
of the user running the upgrade.

As of this release, the installers check the installation directory
to ensure all files and directories have the correct permissions. If
they do not, it exits with an informative error message.
