Upgrade Linux on Your Server

Use this task if you need to upgrade the Linux server operating system on your server in order to upgrade Oracle Communications Session Delivery Manager.

Note:

Ensure that the server is shut down before you do this task. See the Shut Down Your System section for more information on shutting down the SDM server.

Login to the server as the nncentral user.
Change to the SDM software installation bin directory. For example:
```
cd /<sdm-install-directory>/AcmePacket/NNC<version>/bin
```
Run the backupdbcold.sh script.

Note:
The backupdbcold.sh -- help script provides all of the arguments that you can use.
```
./backupdbcold.sh
```
- You can use the following arguments with this script:
  - -d —Use this argument to select a local directory that you want to store backup archives. For example:
```
./backupdbcold.sh -d/<sdm-install-directory>/AcmePacket/<Directory>/NNC<version>_ColdBackup_yyyy_mm_dd_<number>_all.tar
```
  - -a, --all — Use this argument to run all backups and store them as a single archive.
```
./backupdbcold.sh --all
```
  - -c --core — Use this argument to backup the core application database and store it as an individual archive.
```
./backupdbcold.sh --core
```
  - -r --report — Use this argument to backup the reporting Oracle database and repository and store as an individual archive.
```
./backupdbcold.sh --report
```
  - -o --ocsdmdw — Use this argument to backup the (Oracle Communications Session Delivery Manager Data Warehouse (OCSDMDW) database and store as an individual archive.
```
./backupdbcold.sh --ocsdmdw
```
  - -ep, --excludePlugins —Use this argument to exclude archived plugin zip files from the resulting backup file. By default, the resulting backup file contains all product plugin installation zip files which were previously uploaded to SDM. You can override this behavior by entering this command.
```
./backupdbcold.sh --excludePlugins
```
After the script runs, the output displays a section called Backup Results. The output shows if the core SDM application database and reporting databases are successfully backed up to the default DatabaseBackup directory. The following example shows the directory on which the application database file was backed up:
```
/<sdm-install-directory>/AcmePacket/DatabaseBackup/NNC<version>_ColdBackup_yyyy_mm_dd_<number>_all.tar
```
Note:
If you do not have reporting configured on the SDM server, the output shows that the reporting databases failed to be backed up.
Upgrade the server to a supported version of Linux. See Check System Requirements for more information.
Repeat the steps above if you need to upgrade another Linux server on which Oracle Communications Session Delivery Manager needs to run.
