Ansible can certainly be installed using prebuilt packages from the EPEL repository, but while convenient, their offering is limited to Ansible 1.9.x – that is to say only versions prior to the major 2.0 release that includes a number of significant improvements, that were seen further polished in 2.1.
You will, more than likely, want to run 2.1.2, the latest stable release, for any production use, or perhaps the penultimate 2.0.1 release, if you are of a slightly more conservative origin.
I always meant to let my php scripts on my Ubuntu server access Oracle databases, thus quite possibly making it into a Linux, Apache, Oracle and PHP server. I do wonder how you would smoothly pronounce the resulting acronym.
Anyway, I often have the feeling that open source systems and commercial databases are intentionally made to not play well together. Despite myself, I recently found a nice article on how to install Oracle 11g instant client and building php with support for OCI.
I encountered and worked around a couple of issues when installing MediaWiki 1.20.2 with Oracle 11g Express Edition 126.96.36.199.0 as the database back-end. The solutions below can be also applied to MediaWiki 1.20.0 and 1.20.1.
I did the installation on top of Zend Server Community Edition, saving me the trouble of tinkering too much with apache, php and oracle drivers.
If you’re having a rather dull afternoon at the office, and you happen to have an OVCA as your personal playground, you can always try this little trick to spice up your day: Point your browser to the Oracle VM Manager, look for the the network configuration tab and attempt to make the storage and heartbeat network available to virtual machines. I can virtually promise you that your day will be more interesting. Much more. Almost instantly.
If you ever have to restore the Oracle Virtual Machine Manager database using the provided RestoreDatabase.sh, chances are that you will end up with a bunch of corrupted or missing tables in the back-end MySQL database schema. Specifically, all tables with 0 rows will be dysfunctional after successful restore. In turn this prevents management of compute-nodes, virtual machines and other resources.
I don’t know which other versions of OVM might be affected, but the latest 2.0.2 software release for the Virtual Compute Appliance certainly is.
