Installation notes:
-------------------
- Install the patch file dfs-4_7_4-patchHPUX.tar.gz (standard
  installation to be done by J.Parra). The patch contains only
  one relevant file (script) for NGAMS: 

  ~flowmgr/dfs-4_7_4/bin/olasDhsControl

  The new script is in charge of launching the 'ngamsIngest'
  process at boot time.

- As archeso@wvgdhs check the following environment variables:

        DFS_NGAMS_OLAS=YES
        DFS_NGAMS_HOST=wvgnau
        DFS_NGAMS_PORT=7777
        DFS_NGAMS_DATA=/data/ngams-raw

  otherwise reset to the correct values in the 
  ~archeso/.pecs/misc-all.env
  Very likely you will have to add the following lines:

        export DFS_NGAMS_OLAS=YES
        export DFS_NGAMS_HOST=wvgnau

- Check the directory $DFS_NGAMS_DATA exists, otherwise create it
  as 'archeso':

        % mkdir $DFS_NGAMS_DATA
        % chmod 755 $DFS_NGAMS_DATA

- Check the $DFS_NGAMS_HOST is known (in the /etc/hosts), and you
  can reach it with the e.g. 'ping' command:
        
        % /usr/sbin/ping $DFS_NGAMS_HOST

  otherwise ask system manager to add it (Remember: In Paranal 
  there is no DNS service).

- Reboot the machine. After reboot, check the 'ngamsIngest' is
  running in background (owner is 'archeso').

- REMARK: there is no upgrade of the 'ngamsIngest' binary. It is 
  the same as installed during the APRIL commissioning, and it
  is the same binary that is currently working in 'wu3dhs' with
  the VIMOS pre-images.

  The 'ngamsIngest' has been tested in Garching to work with the
  new NGAS servers. However and just in case problems arise, there
  is a new 'ngamsIngest' (compiled with the latest ngamsCClient 
  v2.1.3) available in:

        oddysey4:~flowmgr/dfs-patches/ngamsIngest-v2.1.3
        with checksum: 578533002       1814588

  and ready to be renamed and moved into:

        wvgdhs:~flowmgr/dfs-4_7_4/bin/ngamsIngest
