MySQL TDE: Online key store migration

So, if we’re applying GDPR to our system, and we’re already making use of MySQL Transparent Data Encryption / keyring, then here’s an example on how to migrate from filed-based keyring to the encrypted keyring. Online.

Replicating data from MySQL to Oracle

In our work, We used to get a lot of requirements for replicating data from one data source to another.Previously I wrote replication from MySQL to Red-shift.

In this blog I am going to explain about replicating the data from MySQL to Oracle using Tungsten replicator.

1.0. Tungsten Replicator :

It is an open source replication engine supports data extract from MySQL, MySQL Variants such as RDS, Percona Server, MariaDB and Oracle and allows the data extracted to be applied on other data sources such as Vertica, Cassandra, Redshift etc.

Tungsten Replicator includes support for parallel replication, and advanced topologies such as fan-in and multi-master, and can be used efficiently in cross-site deployments.

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:
