Important Cautions
 | Caution - Ensure that you back up all existing databases before running the Java OneCommand. |
| Caution - You must use the latest version of OEDA and the Java OneCommand patch (patch 19766190 or later). Refer to the Oracle Exadata Deployment Assistant (OEDA) section in MOS Note 888828.1 for details. |
| Caution - Any version of Java OneCommand prior to patch 19766190 can destroy the storage cell disks and griddisk if an undo option is performed on certain steps (Create Cell disk, for example). This can cause complete destruction of all the griddisks on the storage cells. In addition, re-running the griddisk creation step or mistakenly specifying a non-unique diskgroup in OEDA will result in the destruction of existing griddisks. Be aware that older versions of Java OneCommand also destroy cell disks and griddisks with the Create Cell Disks step. |
| Caution - No more that eight zones with an Oracle database are supported on a Database Domain. |
