CVS module that contains the various configuration files used in the various NGAS installations. Install this as user ngasmgr. The following NG/AMS Configuration Files are provided:

For Garching:

For La Silla:

Link to link in the NGAS Configuration Module:

/etc/ngamsServer.conf->/opsw/NGAS/ngasCfg/cfg/ngamsServer.conf.

Must be created manually.

Link to the actual NG/AMS Configuration used by this NGAS system, e.g.

/opsw/NGAS/ngasCfg/cfg/ngamsServer.conf->/opsw/NGAS/ngasCfg/cfg/NgamsCfg.ESOECF.NMU.xml.

This link must be created manually!

NOTE: TBD if we should continue with this scheme with double links in connection with the configuration file -- maybe one is enough.

This directory contains the following files:

ngamsDiskFormat: Used to format disks. Link to /opsw/NGAS/ngasUtils/src/ngamsDiskFormat.py. Link to: /opsw/NGAS/ngasUtils/src/ngamsDiskFormat.py.

ngamsIngest: DHS client to ingest data into NGAS. Only relevant for LS. This process will be moved to the DHS WS.

ngamsIngest_startup: Used to start up ngasmIngest. Link to /opsw/NGAS/ngasUtils/src/ngamsIngest_startup.py.

ngamsPClient: NG/AMS Python Client. Link to the NG/AMS P-Client /opsw/NGAS/ngams/ngamsPClient/ngamsPClient.py.

ngamsCClient: Link to binary of the NG/AMS C-Client (/opsw/NGAS/ngams/ngamsCClient/ngamsCClient).

ngamsServer: NG/AMS Server application. Link to the NG/AMS Server application, /opsw/NGAS/ngams/ngamsServer/ngamsServer.py.

ngasLogProcessor: Used to archive log files at the WFI NAU. Link to /opsw/NGAS/ngasUtils/src/ngasLogProcessor.py.

utilFitsChecksum: Used to calculate the FITS checksum.

All the links + tools mentioned above, have to be made executable for all (chmod a+x ---).

This file must contain the relevant entry for accessing the ESOECF and OLASLS NGAS DBs:

ESOECF 12 10
        query tcp sun-ether acrep1.hq.eso.org 9500
        query tli tcp /dev/tcp \x0002251c86ab02060000000000000000
        query tcp sun-ether acrep1.hq.eso.org 2025
        query tli tcp /dev/tcp \x000207e986ab02640000000000000000

        master tli tcp /dev/tcp \x000207e986ab02640000000000000000

NGAS depends on the following files/modules in this directory:

Sybase.so: Sybase module used to access Sybase from Python.

fitsio.py, pcfitsio.so: Compiled cfitsio binary integrating cfitios into Python.

ngams -> /opsw/NGAS/ngams: Link to the NG/AMS package to make NG/AMS publically available.

pcc -> /opsw/NGAS/pcc: Link to the PCC package to make PCC publically available.

Other files/modules contained in the site-packages directory on an NGAS machine not directly used by NGAS:

Numeric, Numeric.pth, Qfits.py, README, io.py, mx, pstat.py, qfits.so, .stats.py

NGAS depends on the following files/modules in this directory:

ngamsIngest: Only relevant for LS. Start-up script to start the ngamsIngest process (probbaly no relevant anymore on the NGAS system, since it will probably run on the DHS machine. This binary must be delivered by SEG.

ngamsServer: Start-up script for the NG/AMS Server. This is a link to: /opsw/NGAS/ngasUtils/src/ngamsServer.init.sh.

ngasFirewall: Script to set up the firewall used by NGAS. This is a link to: /opsw/NGAS/ngasUtils/src/ngasFirewall.init.sh.

zopeWatchDog: Only relevant for jewel68.hq.eso.org for the moment. Used to supervise the Zope server on jewel68 and to restart it. Link to: /opsw/NGAS/ngasUtils/src/zopeWatchDog.

On jewel68 a cron job is run on a daily basis to check if there are files missing in the NGAS DB compared to the Observations DB.In addition there is acron job to back-up the Zope DB. The cron jobs are as follows:

ngasmgr@jewel68:/etc/init.d> crontab -l
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (crontab installed on Tue Oct 29 14:08:35 2002)
# (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)
00 12 * * * /home/ngasmgr/CRONTAB/ngasCheckMissingFiles.py /home/ngasmgr/CRONTAB/ngasExemptFileList
00 17 * * * rcp /opt/zope/var/Data.fs web@acwebint:/home/web/archive/docs/NGAST/zope/.

On w2p2nau.ls.org a cron job is executed on a daily basis to archive the NG/AMS Log File. The cron job is defined as follows:

ngasmgr@w2p2nau:~> crontab -l
# DO NOT EDIT THIS FILE - edit the master and reinstall.
# (/tmp/crontab.12297 installed on Wed Jan 15 12:43:13 2003)
# (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $)
00 12 * * * /opsw/NGAS/ngasUtils/src/ngasHandleNgamsLogFile.py -host w2p2nau -port 7777 -l /NGAS/ngams_staging/msg/LogFile.nglog -wd /NGAS/ngams_staging/msg/ngasHandleNgamsLogFile

Following environment variables should be defined (normally defined in ~/.bashrc):

NOTE: The definition of env. var.s is not OK. E.g., PATH is growing for each xterm opened, i.e., env. var.s are not created form scratch.

The module contains the sources of the version of Zope used. The Zope DB file is called: /opt/zope/var/Data.fs. This file is copied on a daily basis to acwebint (see Cron Jobs on jewel68 above). It thus can be reovered from the back-up file.

Two scripts in /opt/zope are available for starting/stopping Zope: /opt/zope/start and /opt/zope/stop.

Two accounts are needed: ngas and ngasmgr: --- DSU: GET UIDs alloacted by HelpDesk for these users

ngas:x:501:501::/home/ngas:/bin/bash
ngasmgr:x:500:500::/home/ngasmgr:/bin/bash

Should contain the following two entries:

root ALL=(ALL) ALL
ngasmgr ALL = NOPASSWD: /opsw/NGAS/bin/ngamsDiskFormat

Only relevant for the Garching AHU.
