Ansible Dynamic Inventory for Oracle Enterprise Manager

Ansible Dynamic Inventory for Oracle Enterprise Manager

A python script to generate an Ansible inventory based on an Oracle Enterprise Manager (OEM) repository database.

Based on an example of the book Ansible for DevOps.

Validated against OEM 13.4.

Groups are dynamically created based on the following properties:

• Repository name (section name in the config.ini file)
• Lifecycle Status
• Line of Business
• Operating System family (e.g.: AIX, Linux, Windows)
• Operating System version (e.g.: Windows Server 2012 Enterprise, Oracle Linux 6.4, Oracle Linux 7.9)

Requirements

• Python 3.x
• cx_Oracle
• Oracle Client or Oracle Database installed on the same host
• Repository User Privileges:
  • select on "REPOSITORY_OWNER".mgmt$target
  • select on "REPOSITORY_OWNER".mgmt$target_properties
  • Synonyms for "REPOSITORY_OWNER".mgmt$target and "REPOSITORY_OWNER".mgmt$target_properties

Instructions

• Ensure that the packages python3 and python3-pip are installed (RHEL 7.x / OEL 7.x).
• Install cx_Oracle with pip3. If you don't have root access, a local install for your user is enough.

pip3 install -U cx_Oracle --user

• Download the latest release and unzip it on a directory. The files ansible_oem_inventory.py and config.ini.template must exist on the same directory.
• Rename config.ini.template to config.ini and fill in the repository connection variables.
• If you need additional static variables, the group_vars and host_vars directories must be created on the same directory that the ansible_oem_inventory.py is stored.
