PostgreSQL Conference Europe 2014

I attended to PostgreSQL Conference Europe 2014. It was held October 21-24 at Madrid. I do not know the exact number of attendees but there were some sessions that you can not find seat and have to listen while standing up on a corner. As an Oracle DBA, PostgreSQL is a different world to me. I tried to follow the DBA track and gather as much information as I can. Unfortunately the level of DBA tracks are not deep enough for me. The most topics are designed for developer or system admins who also manage PostgreSQL Databases as a side-mission. I feel like most attendees are developers and see that a database management system should manage itself with almost zero-maintenance. This is the same approach of Microsoft SQL Server users/developers. They see the database as a part of their development environment, and expect it to behave like a answering machine. Anyway there were still interesting sessions and watching the presentations of PostgreSQL Developers was a unique opportunity.


Configuring Oracle SQL Developer for PostgreSQL

I see that some people wonder if Oracle SQL Developer can be used with PostgreSQL. I wrote a blog post to show how you can configure Oracle SQL Developer to connect Microsoft SQL Server and MySQL. You can use the same method to configure SQL Developer for PostgreSQL. First we need to download a compatible JDBC driver from PostgreSQL site. Latest version of SQL Developer uses JDK 1.7, so we can download the JDBC41 Postgresql Driver:


Then we open Oracle SQL Developer, open preferences, database section and third party JDBC driver.

Oracle Enterprise Manager Cloud Control 12c Plugin for PostgreSQL

In my company, we use PostgreSQL, Postgres Plus (a commercial fork of PostgreSQL provided by EnterpriseDB) beside Oracle databases. Unfortunately different databases need different tools to monitor, and implementing a standard monitoring procedure for all databases becomes a real problem. Good thing is Oracle Enterprise Manager is an extendable software supporting 3rd party plugins, and there are companies like Blue Medora which focuses on the product enhancements for Enterprise Manager. Blue Medora released a plugin to monitor PostgreSQL for Oracle Enterprise Manager, and I just deployed it to our servers. In this blog post, I’ll try to give brief instructions to set up the plugin.

First you need to download the plugin from Blue Medora website. I do not know when it will be added to self-update of Enterprise Manager but for now, you need to downloaded it manually. After you download the zip file, copy the zip file to your Enterprise Manager 12c server, and unzip it. I unzip it to a folder called postgre_plugin (under home directory of oracle user):

The zip contains a file named “bm.em.xpgs_12.”. It’s the plugin file which we’ll need to import to Enterprise Manager. We’ll use “emcli” to login to Enterprise Manager, and then import the plugin:

I divided the last command to two lines, using \ symbol, so it fits into the code-window on my website but you may write it one line (without \ symbol).
