MySQL Plugin For Oracle Enterprise Manager 13c Cloud Control

This is the same plugin that Alex Gorvachev created back in the day. I’ve simply modified it to be compatible with both 12c and 13c versions.

I created this in response to a comment on the blog about issues deploying the plugin in OEM 13c. There is also a note in MOS “EM 13c: Adding a MySQL Instance in Enterprise Manager 13c Fails with Error: oracle.sysman.emSDK.agent.client.exception.NoSuchMetricException: the Load metric does not exist (Doc ID 2160785.1)“.

This version has been tested with OEM 13cR2 and OEM 12cR3, so it should be working in all the versions in between except for bugs.

Caveats

Upgrading MySQL to 8.0.12 with Audit plugin.

As a spin-off from the previous post, https://mysqlmed.wordpress.com/2018/08/23/get-the-auditors-in/, I thought that it would be good to see how well the Audit plugin upgrades to MySQL 8. The big change in auditing is that the tables change from MyISAM to InnoDB, so keep your eyes open.

I’m using the previously used instance in version 5.7.18.

Preparation

Before we do anything, let’s make sure auditing will be in place when we restart the instance with 8.0.12:

Uncomment the plugin-load & audit-log params we had originally commented out. After all, this is something we should have done in the last post (apologies!):

vi my_audit.cnf:
  ..
  [mysqld]
  plugin-load =audit_log.so
  audit-log =FORCE_PLUS_PERMANENT
  ..

Restart the 5.7 instance so we upgrade from a rebooted / ‘as real as can be …

Get the Auditors in: MySQL Enterprise Audit.

Here I have been looking into using the MySQL Enterprise Edition Audit Log plugin for 5.7. We have many options to audit (filters, encryption, compression, Workbench, rotation & purging, viewing the log, etc.) and it’s quite clear cut on what we’re auditing and not when active.

If you’re looking to go deep into the Audit Plugin, as part of the Enterprise Edition, you’ll want to look at the following Support note:

Master Note for MySQL Enterprise Audit Log Plugin (Doc ID 2299419.1)

And if you’re looking for other Audit Plugin examples, I’d recommend Tony Darnell’s blog post:

Porting this Oracle MySQL feature to MariaDB would be great ;-)

Oracle has done a great technical work with MySQL. Specifically a nice job has been done around security. There is one useful feature that exists in Oracle MySQL and that currently does not exist in MariaDB. Oracle MySQL offers the possibility from within the server to generate asymetric key pairs. It is then possible use [...]

What's Right and What's Wrong With Oracle's Way of MySQL Server Development

Recently it's quite common to state that "Oracle's Acquisition Was Actually the Best Thing to Happen to MySQL". I am not going to argue with that - Oracle proved over years that they are committed to continue active development of this great open source RDBMS, and they have invested a lot into making it better and implementing features that were missed or became important recently. Unlike Sun Microsystems, they seem to clearly know what to do with this software to make it more popular and make money on it.

Among the right things Oracle does for MySQL server development I'd like to highlight the following:

  1. MySQL server development continues, with new features added, most popular OSes supported, regular releases …

a critical piece is missing for Oracle MySQL 8 (GA) …

Oracle MySQL 8.0 has been declared GA but a critical piece is missing … MySQL 8 is a fantastic release embedding the work of brilliant Oracle engineering. I will not detail all the great features of MySQL 8 as there are a lot of great presentations around it. https://mysqlserverteam.com/whats-new-in-mysql-8-0-generally-available/
