Metacat

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

	-- 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
