To Do an Online Backup

The following procedure guides you the following tasks.

• Running a cold backup for contingency.

• Enabling ARCHIVELOGMODE, which shuts down Sun Management Center and sets up archiving.

• Backing up the database online.

Steps

1. (Optional) Do a cold backup

   1. Become superuser by typing:

      % su -

   2. Type this command:

      #/opt/SUNWsymon/sbin/es-backup

      Where /opt is the directory in which Sun Management Center is installed.

      Since the script will shut down Sun Management Center, you are prompted to confirm.

   3. Type y and press Enter.

      You are prompted for the full directory path to store the backup data files.

   4. Press Enter to accept the default directory or type a new path.

      The script creates the backup files and then restarts the product.

2. Enable ARCHIVELOGMODE

   1. Become superuser by typing:

      % su -

   2. Type this command:

      #/opt/SUNWsymon/sbin/es-config -a enable

      Where /opt is the directory in which Sun Management Center is installed.

      You are prompted to confirm that you want to enable archiving.

   3. Type y and press Enter.

      Since the script will shut down Sun Management Center, you are prompted to confirm the shutdown.

   4. Type y and press Enter.

      The script shuts down the product and informs you that a cold backup is recommended. You are prompted to confirm that you want to set up the database in archivelogmode.

   5. Type y and press Enter.

      You are prompted for the full directory path to store the archivelog files.

   6. Enter the full directory path to store the archivelog files, for example:

      /var/opt/SUNWsymon/archives

      The script creates the directory if it does not exist and enables archivelogmode. You are prompted to start the agent and server components.

   7. Type y and press Enter.

3. Run the online backup.

   1. Type this command:

      # /opt/SUNWsymon/sbin/es-backup -o

      You are prompted for the full directory path to store the backup data files.

   2. Press Enter to accept the default or type a different path, for example:

      Enter the full directory path to store the backup data files

      [/var/opt/SUNWsymon/backup]:

      /var/opt/SUNWsymon/mybackup

      ---

      Note –

      If you accept the default directory and later plan to uninstall the product, your backup files might be deleted. Before uninstalling the product, move the backup files to another location. Alternatively, use a different path for your backup files.
