Upgrading to Version 6.8.1 of the LDM Software

If this is the initial install of the NOAAPORT Receive System on your system, go to Installing and Configuring the NOAAPORT Receive System.

Complete the instructions below only if you have already installed a previous version of the NOAAPORT Receive System, and are simply upgrading to version 6.8.1 of the LDM software. If you are also upgrading the DVB reader software to version 1.4.1, make sure you upgrade this LDM software first (before upgrading the DVB Reader software).

Notes:

• Do not delete existing ~ldm/data, ~ldm/etc and ~ldm/logs directories, as they contain important files that must not be deleted (e.g., ~ldm/etc contains configuration files such as pqact.conf and ldmd.conf). The LDM upgrading procedures on this page will not overwrite these directories and files.
• The ~ldm/data and ~ldm/logs directories should not be part of any automated backups due to the volatility of the data that they will contain.

Complete the instructions below to upgrade to version 6.8.1 of the LDM software.

1. On your NOAAPORT ingest computer logon as user ldm.


2. Download ldm-6.8.1.tar.gz to the ~ldm directory.


3. Stop the LDM software. Type:

   ldmadmin stop

4. Build and install the LDM software.
   1. Unpack the LDM files. Type:

      gunzip -c ldm-6.8.1.tar.gz | tar xvf -

   2. Remove the existing runtime symbolic link. Type:

      rm runtime

   3. Remake the runtime symbolic link to the new ldm directory. Type:

      ln -s ldm-6.8.1 runtime

   4. Build and install the LDM software. Check the log file after each step for errors before moving on to the next step. Type:

      cd src
      ./configure > configure.log 2>&1
      make > make.log 2>&1
      make install > install.log 2>&1

   5. Set internal communications. Type:

      sudo make install_setuids

      Note: You will be required to enter user root's password to complete the above command.
5. Restart the LDM software. Type:

   ldmadmin start
