Stand-alone Upgrade

This process incurs system downtime; your Oracle Communications Session Border Controller stops passing traffic for a period of time. Please plan for your standalone upgrade accordingly.

Software Upgrade Procedure

The following procedure describes how to upgrade a Oracle Communications Session Border Controller with a new software image. In this procedure, the image file is located on the Oracle Communications Session Border Controller’s local file system in /boot.

To upgrade a software image on a stand-alone system:

Change the boot configuration parameters to use the new image.
Note:
Changing the file name boot parameter configuration, as shown below, performs the same function as running the set-boot-file command.

In the ACLI configure terminal menu, type bootparam and press <Enter> to display the list of boot parameters. Scroll through the boot parameters by pressing Enter. Stop when you reach the file name boot parameter and type the appropriate file name next to the previous file name. Press <Enter> to continue scrolling through the boot parameters.

The following example uses the filenames /boot/nnSCZ840m5.64.bz and /boot/nnSCZ900.64.bz.
```
SBC1# configure terminal
SBC1(configure)# bootparam
'.' = clear field;  '-' = go to previous field;  ^D = quit
boot device          : eth0
processor number     : 0
host name            : boothost
file name            : /boot/nnSCZ840m5.64.bz /boot/nnSCZ900.64.bz
```
Reboot the Oracle Communications Session Border Controller using the reboot command.

The Oracle Communications Session Border Controller should now be successfully running the new release.
