The Easiest Way to Enable Oracle Database Application Development on Mac OS X

tl;dr Your OS X applications can connect to Oracle Database as if

How I Enable Autostarting of Oracle Database for Demonstrations and Development

Here are the steps I have been using to enable autostarting of
Oracle Datbase Enterprise Edition 10g, 11g or 12c during boot time of
Oracle Linux 5 and 6. I also use these steps with Oracle Linux
7. These steps are useful for the kinds of demonstration and
development setups that I typically need.

These steps are not needed for Oracle XE, since its install will
prompt whether to autostart the DB and will configure the system
automatically.

Install Windows 7 with VirtIO Drivers on RHEV 3.4

One of the best ways to improve the performance of Microsoft Windows guest is to use paravirtualised devices and drivers for KVM in the guests. This provides close to bare performance (up to 95%). These drivers are provided by the virtio-win RPM packages in the RHEL.
1. The virtio-win packages can be found on RHEL server /usr/share/virtio-win/

We are looking to hire someone who loves working with open source developer communities.

We are looking to hire someone who loves working with open source developer communities.

The ideal candidate would have experience with the Oracle Database and at least two or more open source developer environments. The successful candidate would join a team of people responsible for helping database app developers be more productive while using prominent open source development tools. That person would also help to represent the needs of the community back to Oracle development.
