This role will upgrade an Oracle database. The role is is divided into 3 sections that should be run in this order:

1. pre_upgrade.yml (no downtime if database is in archivelog mode)
1. `pre_upgrade.yml` (no downtime if database is in archivelog mode)
- run 24 hrs before planned database upgrade
- runs pre-upgrade oracle script, performs full (level 0) backup, runs fixup scripts.

2. upgrade.yml (Downtime is required!)
2. `upgrade.yml` (Downtime is required!)
- performs incremental (level 1) backup, enables flashback database and creates guaranteed restore point. Runs manual database upgrade. Takes another full backup after upgrade is complete.

3. upgrade_final.yml (no downtime if database is in archivelog mode)
3. `upgrade_final.yml` (no downtime if database is in archivelog mode)
- run 7 days after upgrade to finalize
- deletes guaranteed restore point before setting database compatibility parameter. Takes full backup (level 0).

### Optional Tags
To skip these optional tags use `--skip-tags` when running the playbook. For example, if you do not want to run RMAN backups before or during the upgrade you would execute these commands:

```
# Pre-Upgrade checks without backups
ansible-playbook 12c_1_pre_upgrade.yml -i <path_to_inventory> --extra-vars="hosts=<hostname>" --skip-tags="pre_upgrade_backup"

# Upgrade database, do not backup database.
ansible-playbook 12c_2_upgrade.yml -i <path_to_inventory> --extra-vars="hosts=<hostname>" --skip-tags="backup"

# Post-Upgrade tasks, do not backup database.
ansible-playbook 12c_3_upgrade_final.yml -i <path_to_inventory> --extra-vars="hosts=<hostname>" --skip-tags="final_upgrade_backup"
```
`pre_upgrade_backup` - Level 0 backup that runs during pre-upgrade checks. If this is skipped do not run subsequent Level 1 backups.
`archivelog` - Run during pre-upgrade playbook. Shuts down database and enables archivelog and flashback database.
