Exadata Database Machine is a complete, integrated rack system that contains both hardware and software for running Oracle Database.\\
==== Patch order ====
Patching it is done on a per-component basis and in general, in this order:
=== Infiniband Switches ===
  *  Spine
  *  Leaf
Infiniband Switch patches may not be cumulative - needs to be checked in the README.

=== Storage Server Software ===
  *  Cell nodes
  *  Database Minimal Pack in compute nodes
These patches are usually launched from compute node 1 using dcli and ssh to remotely patch each cell node.\\
Patches can be applied in a rolling fashion or standalone.\\
Rolling
<code>
./patchmgr -cells <cells group> -patch_check_prereq -rolling
./patchmgr -cells <cells group> -patch -rolling
</code>
Standalone
<code>
./patchmgr -cells <cells group> -patch_check_prereq
./patchmgr -cells <cells group> -patch
</code>
Check the log files:
  *  /var/log/cellos/validations.log
  *  /var/log/cellos/vldrun*.log

=== Database server patch ===
  *  Grid Home (if applicable)
  *  Oracle Home
These patches are specific to Exadata - so download the right ones.\\
They are, however, installed using the standard opatch mechanism.

=== CRS MLR patches ===
  *  Grid Home
  *  Oracle Home (if applicable)
