Installing site MON box for LCG 2.3.0 on SLC 3.0.4


Get guide from
http://grid-deployment.web.cern.ch/grid-deployment/documentation/LCG2-Manual-Install
I used guide v2.3.0


Install a "standard" SLC box. Make sure you include GCC and CPP, 
and I tried to avoid everything that would need X11.

Avoid MySQL and anything CERN specific.
Remove CERN related stuff from /etc/pine.conf

Setup NTP client, as per instructions.

Get and install YAIM, and fill out the site-info.def.

Install packages:
	/opt/lcg/yaim/scripts/install_node site-info.def lcg-MON 

Follow the instructions that the mysql RPMs give about setting up 
passwords.

Configure packages:
	/opt/lcg/yaim/scripts/configure_MON site-info.def

If using R-GMA 3.4.35, get new /opt/edg/libexec/edg-rgma-restart-all at
	http://hepunx.rl.ac.uk/egee/jra1-uk/LCG/current-release.html

Fill out site details in 
	/opt/edg/var/edg-rgma/rgma-tools-defaults 

Restart R-GMA, the R-GMA tests should then work
	/opt/edg/sbin/test/edg-rgma-check

	/opt/edg/sbin/test/edg-rgma-run-examples

APEL
Get APEL 3.4.41 from
	http://goc.grid-support.ac.uk/gridsite/accounting/
and install.

Use FQDN of MON box in 
	/opt/edg/etc/edg-rgma/apel.xml 
and ensure this file is only accessible by root (chmod 600)



Missing R-GMA performance tweaks:
I've made the following changes:

In  /opt/edg/share/webapps/R-GMA/WEB-INF/web.xml
change maxTupleMemory for all servlets to -1.
(restart Tomcat)
(-1 = unlimited; I've also seen 358 used)


In /etc/tomcat4/tomcat4.conf add

	ulimit -n 16384
	# Java VM options for memory control
	JAVA_OPTS="-Xms64m -Xmx1024M"

The JAVA_OPTS line will break rgma_config, so must be commented out 
whenever the configuration is repeated, either directly or by 
.../yaim/scripts/configure_MON.

(I'm not sure the ulimit doesn't have to be set in
 $EDG_LOCATION/etc/init.d/edg-tomcat4 )
