Update Other MiniCluster Software Components (CLI)

Language:

Use this procedure to update any software component that has an update available, except for the MCMU component (use Update the MCMU Component (CLI) instead).

Alternatively, you can perform the same updates using the BUI, which is less prone to human error. See Update MiniCluster Software (BUI).

The system can be updated while DB and App VMs are running.

This tables lists mcmu patch syntax for various components.

Note - The components and options differ from version to version. To see the full list of patch options for your particular version, perform the help command: mcmu patch -p -h.

Component	Syntax
Storage array firmware	`mcmu patch -p update_jbod`
GI and ACFS in kernel zones	`mcmu patch -p update_acfs`
OS repository (used to install and update VMs and global zones)	`mcmu patch -p update_repo`
Kernel zone OS	`mcmu patch -p update_kz`
Compute node OS (both nodes)	`mcmu patch -p update_gz`
Oracle ILOM on the compute nodes (both nodes) Note - Depending on the POST configuration, this update can take 40 - 50 minutes to complete.	`mcmu patch -p update_ilom`
GI in DB VMs	`mcmu patch -p update_gi` `-z` `DBgroup_name`
Oracle DB home	`mcmu patch -p update_oh -z` `DBgroup_name--ohDBhome_full_path`

Ensure that the Patch Bundle is downloaded to MiniCluster.
These procedures must be performed prior to updating the software components:
1. Download the Patch Bundle.
  See Check for and Obtain the Latest Updates.
2. Unzip and extract the bundle.
  See Extract the Patch Bundle.
Log into the MCMU CLI as a primary admin, such as mcinstall.
See Log in to the MCMU CLI.
Display the help output to see which update options are available on your system.
```
% mcmu patch -h
```
Update one or more components.
Key points:
- Some component update options can be included on a single command line, separated with commas.
- These component options can only be updated individually (not combined on a command line): update_gz, update_ilom, and update_omctoolkit
- A system reboot (one node at a time) is automatically performed after updating each of these component options: update_gz and update_ilom
- The GI and Oracle DB homes must be at the same revision levels. When you patch these components, patch the GI before you patch a DB home.
- Some component options require additional command line arguments, as shown in the examples.
Examples:
- Example of updating the compute node firmware:
```
% mcmu patch -p update_ilom
```
- Example of updating the GI in VM group called mc5dbzg1:
  
  The first command in this example (describe in List a Summary of All DB VM Groups (CLI)) displays the DB VM group name that is needed for the mcmu patch command.
```
% mcmu tenant -G -l
Listing DB VM Group...
Status : Active
Description :
VMgroupName : mc5dbzg1
editable : True
deletable : True
progress : False
VMgroupID : 1

% mcmu patch -p update_oh -z mc5dbzg1
```
- Example of updating the DB in VM group called mc5dbzg1 for the DB home at /u01/app/oracle/product/12.1.0.2/dbhome_1:
  
  The first two commands display the DB VM group name and the full path of the DB home that are needed for the mcmu patch command. These commands are described in List a Summary of All DB VM Groups (CLI) and List Details for a DB Home (CLI).
```
% mcmu tenant -G -l
Listing DB VM Group...
Status : Active
Description :
VMgroupName : mc5dbzg1
editable : True
deletable : True
progress : False
VMgroupID : 1

% mcmu tenant -H -L 2
DB HOME INFORMATION
ID: 2
VM_ID: 2
VMGROUP_ID: 1
DB_HOME: /u01/app/oracle/product/12.1.0/db_12c
VERSION: 12.1.0.2
TYPE: RAC
PATCH: 12.1.0.2.160419
STATUS: Active

% mcmu patch -p update_oh -z mc5dbzg1 --oh /u01/app/oracle/product/12.1.0.2/dbhome_1
```
- Example of updating multiple components (GI and OS in the kernel zone, and the storage array firmware) on one line:
```
% mcmu patch -p update_acfs,update_kz,update_jbod
```
Consider your next action.
