On a virtual machine with Ubuntu 14.04 Long Term Support (LTS) where you plan to install Update Manager Download Service (UMDS), configure a PostgreSQL database instance.


  • Create a virtual machine for UMDS on the management cluster of Region A. See Virtual Machine Specifications from the Planning and Preparation documentation.


  1. Log in to vCenter Server by using the vSphere Web Client.
    1. Open a Web browser and go to https://sfo01m01vc01.sfo01.rainpole.local/vsphere-client.
    2. Log in using the following credentials.



      User name




  2. In the vSphere Web Client, right-click the sfo01umds01 virtual machine and select Open Console to open the remote console to the virtual machine.
  3. At the command prompt, log in as the svc-umds user using svc-umds_password.
  4. Install Secure Shell (SSH) server, and end the session.
    sudo apt-get update
    sudo apt-get -y install SSH
  5. Log back in to the UMDS virtual machine using Secure Shell (SSH) client and the svc-umds service account credentials.
  6. Install and start PostgreSQL and its dependencies:
    sudo apt-get -y install vim perl tar sed psmisc unixodbc postgresql postgresql-contrib odbc-postgresql
    sudo service postgresql start

    The installation procedure creates a user account called postgres that is associated with the default Postgres role. We'll use the postgres account to establish a service account the Update Manager Download Service will use.

  7. Log in as a PostgreSQL user, and create a database instance and a database user, by running the following commands.

    When prompted, enter and confirm the umds_db_user_password password.

    sudo su - postgres
    createdb umds_db
    createuser -d -e -r umds_db_user -P
  8. Enable password authentication for the database user.
    1. Navigate to the folder that contains the PostgreSQL configuration file pg_hba.conf.

      Linux system

      Default Location

      Ubuntu 14.04


      cd /etc/postgresql/postgres_version/main
    2. In the PostgreSQL configuration file, enable password authentication for the database user by inserting the following line right above local all all peer.

      You can use the vi editor to make and save the changes.










    3. Log out as a PostgreSQL user by running the following command.
  9. Configure the PostgreSQL driver and the data source name (DSN) for connection to the UMDS database.
    1. Edit the ODBC configuration file.
      sudo vi /etc/odbcinst.ini
    2. Replace the file with the following content and save the change using :wq.
      Description=PostgreSQL ODBC driver (Unicode version)
    3. Edit the system file /etc/odbc.ini.
      sudo vi /etc/odbc.ini
    4. Replace the file with the following content and save the change using :wq,
      ;DB_TYPE = PostgreSQL
      ;SERVER_NAME = localhost
      ;SERVER_PORT = 5432
      ;TNS_SERVICE = <database_name>
      ;USER_ID = <database_username>
      Driver = PostgreSQL
      DSN = UMDS_DSN
      ServerName = localhost
      PortNumber = 5432
      Server = localhost
      Port = 5432
      UserID = umds_db_user
      User = umds_db_user
      Database = umds_db
  10. Create a symbolic link between the UMDS and the PostgreSQL by running the following command.
    ln -s /var/run/postgresql/.s.PGSQL.5432 /tmp/.s.PGSQL.5432
  11. Restart PostgreSQL.
    sudo service postgresql restart
