installWorkflowScheduler.txt

These are the steps to install the workflow scheduler, workflow run engine and kepler.  
At the time of this writing, the workflow scheduler is associated with a single instance
of metacat.  The workflow run engine and kepler are installed on the same machine as the 
workflow scheduler.

These instructions assume that you already have a working copy of apache and tomcat.

Build the workflow scheduler:
	-- check out Metacat trunk code
	-- in the root directory, run "ant clean war -f workflowscheduler.build.xml"
	-- the workflowsheduler.war file will be in ./workflowscheduler.dist/
	
Deploy the workflow scheduler:
	-- copy the workflowscheduler.war file to the tomcat webapp directory on the target 
	   server
	-- unjar the war file so you can modify the configuration
		-- in the webapp dir, mkdir workflowscheduler
		-- cd workflowscheduler
		-- jar -xvf ../workflowscheduler.war
	-- vi WEB-INF/workflowscheduler.properties
		-- change the workflowScheduler.authServiceUrl and 
		   workflowScheduler.authorizationServiceUrl to point to the instance of metacat
		   associated with the scheduler.
		  
Create the database:
	-- follow the instructions in the following file in this directory:
		createWorkflowSchedulerDB.txt

Configure Metacat:
	-- on the instance of Metacat associated with this workflowscheduler, edit 
	   WEB-INF/metacat.properties
	-- change the workflowScheduler.url to point to the workflow scheduler server

Restart:
	-- Restart the tomcat instance for the scheduler and for metacat.
	
Install R
	-- follow the instructions at: http://cran.r-project.org/doc/manuals/R-admin.html
	   to download and install r
	-- for rhel4, the following steps were applied
		-- download source tar.gz at:
				 http://cran.cnr.berkeley.edu/sources.html
		-- tar -xvzf R-2.10.0.tar.gz
		-- install gcc: up2date gcc-g77
		-- run configure with no x and no readline options
				./configure --with-x=no --with-readline=no
		-- run "make"
		-- run "make install"
		
Install kepler:
	-- mkdir /usr/kepler
	-- cd /usr/kepler
	-- svn co https://code.kepler-project.org/code/kepler/trunk/modules/build-area
	-- cd build-area
	-- ant change-to -Dsuite=wrp
	-- ant run 
	-- close kepler 
	-- ant startup-script       

Install workflow run engine:
	-- follow the steps listed in:
		http://code.kepler-project.org/code/kepler/trunk/modules/webservice/KeplerWebService/doc/kepler-execution-engine-installation.txt
