Announcing MySQL Plugin for Oracle Enterprise Manager 12c Cloud Control

MySQL management plugin for EM 12c has been long overdue. I’ve initially migrated the older plugin to EM 12c about 6 months ago, and few dozen people received this as the initial beta of the plugin. It worked OK but didn’t use any of the new 12c features, and its home page was a bit of a mess in the EM 12c Cloud Control web interface.

I’ve had lots of new features to add, but I didn’t really have much time to invest into completing them all. Finally, I decided to just finish the home page dashboard and clean it up from all unfinished new features. I did, however, finish MySQL Slave configuration and status monitoring, which was the largest gap in the the functionality of the previous plugin. There is no custom UI for MySQL slave management yet (that’s coming), but monitoring is available as standard metrics and configuration management …

MySQL Plug-in for Oracle Grid Control: Reports Fail with ORA-01017 or ORA-28000

One MySQL Plug-in customer reported an issue with reports — all charts were displaying an Oracle error and didn’t display any data as if it couldn’t connect to the EM repository. I concluded that this has nothing to do with the plug-in itself since the extensibility framework provides no way of controlling usernames and passwords that are used to access the repository. After opening an SR with Oracle, it turned out that MGMT_VIEW user password has been changed and this causes “ORA-01017: invalid username/password; logon denied” and possibly subsequent “ORA-28000: the account is locked” when policy is set to auto lock an account after certain failed login attempts (default in 11g database).

If you face this issue, follow My Oracle Support Note 374382.1 “Grid Control Repository: How to Change the …

Liveblogging: Edward Screven State of the Dolphin Keynote

Chief Corporate Architect at Oracle, been at Oracle since 1986, technology and architecture decisions, responsible for all open source at Oracle. Company-wide initiatives on standards management and security —

Where MySQL fits within Oracle’s structure.

Oracle’s Strategy: Complete. Open. Integrated. (compare with MySQL’s strategy: Fast, Reliable, Easy to Use).

Most of the $$ spent by companies is not on software, but on integration. So Oracle makes software based on open standards that integrates well.

Most of the components talk to each other through open standards, so that customers can use other products, and standardize on the technology, which makes it much more likely that customers will continue to use Oracle.

Oracle invested …

Alex Gorbachev at Oracle Open World 2009: Speaking Schedule

Oracle Open World 2009 is just few weeks away and I firmed up my presentation schedule now. I will present three “normal” presentations and couple unconference sessions.

Announcement: Release 1.1.1 of MySQL Plug-in for Oracle Enterprise Manager

I have just released a new version of the MySQL plug-in for Oracle Enterprise Manager — MySQL plug-in 1.1.1. This is a long overdue bug fix release.

There are no new features implemented (we have another branch in development) but just fixed number of fairly annoying bugs that I was finally able to reproduce.

The download link is on the plug-in’s home page where you can also find a data-sheet and installation guide.

Here are the changes in the 1.1.1 release:

  • Tested with Oracle Enterprise Manager Grid Control 10g Release 5 (

MySQL Management Plug-in and Grid Control Extensibility at Oracle Open World 2008?

In case you are attending Oracle Open World 2008, the biggest Oracle conference in the world, and interested in either (or both) MySQL or Oracle Enterprise Manager Extensibility — I posted a proposal for a new presentation:

Extending Oracle Enterprise Manager by Example — Creating MySQL Management Plug-In

I’ve started looking into Oracle extensibility several years ago and since then I’ve seen lots of improvements in Extensibility Guide and many new plug-ins have seen the light of the day. However, creating a new plug-in is still considered to be something special and not available to mere mortals.
In this presentation we will see how easy it is to create a new plug-in. What are the steps …

MySQL plug-in 1.1 for Oracle 10g Grid Control

It’s been a while since the MySQL Management Plug-in 0.42 was released. Since then, I quietly updated it to version 1.0. The changes were very few; the biggest news was that the plug-in was certified by Oracle and added to OTN Oracle 10g Grid Control Extensions Exchange (see at the bottom).

I think the next version is due, as a few people have come back to me with some issues. The biggest was compatibility with Windows. Since I used the command line MySQL client, *nix and Windows shell incompatibilities were a major headache to solve, and I still couldn’t make it work reliably. I wanted to use DBI and DBD:MySQL, but it required installing and compiling Perl packages, which makes the deployment process very …

MySQL Plug-in for Oracle Grid Control Announced, Released

Hello everyone,

Reading PlanetMySQL today, I discovered that Alex Gorbachev’s announcement that he has released the first public beta of his Oracle Grid Control plugin for MySQL was not aggregated! This is probably because Alex is primarily working on our Oracle space and so his feed isn’t on planet.

This plugin has been under development since 2006 and this is a major achievement.

Knowing that my feed is aggregated, and not willing to let this news and this amazing work go unnoticed by the MySQL community during the conference (I am at MySQLConf listening to’s CTO speak right now!)

In any event, if you missed them inline up there, here’s …

MySQL Plug-in 0.42 for Oracle Grid Control: First Beta Released

It has finally happened! The first public release of the MySQL plug-in for Oracle Enterprise Manager 10g Grid Control is out.

It’s been a while since I first started to work on this, first as part of the Grid Control Extensibility article that I wrote for IOUG SELECT Magazine in 2006 (thanks to John Kanagaraj for encouraging me to write it), and then later as part of a demo for my
