Table 5 - Some core epic4 applications
Mozilla and plugins
Though Mozilla is installed as a base package with Redhat 7.3, I have always made an effort to
keep it up to date, as Mozilla is under constant development and its new features are
invariably useful. Mozilla RPMs can be downloaded from the Mozilla website.
Acrobat and the Java SDK provide plugins for Mozilla. Mozilla’s plugins are stored in
/usr/lib/mozilla/plugins – as I’ve created softlinks to these, they should survive any
upgrades of Mozilla, Java and Acrobat.
IDL
IDL is one of our most used applications, and also the one that causes the most problems with
upgrades and changes to the system because of its copy protection scheme.
IDL runs a licence manager daemon (called lmgrd) which requires a valid licence file. Without
a valid licence file or if the daemon stops for some reason, IDL runs in demonstration mode
allowing only seven minutes of operation before it shuts down.
Our IDL licence allows six concurrent instances of IDL to run. The licence manager daemon is
started at boot time by a couple of commands in /etc/rc.local:
# Start the IDL licence manager
export LM_LICENSE_FILE=/usr/local/rsi/license/license.dat
/usr/local/idl/bin/lmgrd -c /usr/local/rsi/license/license.dat >> /var/log/rsi_lmgrd
license.dat is the IDL license file – this is provided by RSI. Whenever a new version of IDL is
released, RSI send me a new license file to go with it. Enquiries about IDL license matters
should be directed to uksupport@rsinc.com
.
Libraries for IDL which aren’t supplied with IDL itself belong in /usr/local/lib/idl. The
environment variable IDL_PATH, set in /etc/csh.cshrc points to this directory – anything
within it is available to IDL.
Currently, only the IDL Astronomy Library (from http://idlastro.gsfc.nasa.gov/homepage.html
)
is present there.
