*****Install Java 1.6

If Java 1.6 is not installed on your system then follow the instructions
at http://java.sun.com/ to down load and install Java 1.6.

*****Install Apache Tomcat 6.0

Follow the instructions at http://tomcat.apache.org/ to down load and install
Tomcat version 6.0.

*****Install MySQL

If not already install, then follow the instructions at
http://dev.mysql.com/downloads/ to install MySQL 5.0 or better.

*****Install MySQL Connector/J

Down load MySQL Connector/J from http://dev.mysql.com/downloads/connector/j/5.1.html
and install the mysql-connector-java-???-bin.jar into the lib/ext directory of your
Java 1.6 installation home.

*****Create ACToR & ToxRefDB accounts in MySQL

As root in MySQL create ACToR account using the following example
mysql> grant all on actor_2010q4a.* to 'my_actor_user'@'localhost' identified by 'my_actor_pass';
mysql> grant all on toxrefdb_2010q1b.* to 'my_actor_user'@'localhost' identified by 'my_actor_pass';
mysql> grant all on toxminer_v17.* to 'my_actor_user'@'localhost' identified by 'my_actor_pass';

*****Create ACToR & ToxRefDB Databases

login into MySQL with newly created user and password.
mysql -u my_actor_user -pmy_actor_pass

create database.
mysql> create database actor_2010q4a;
mysql> create database toxrefdb_2010q1b;
mysql> create database toxminer_v17;

*****Download ACToR

From http://actor.epa.gov/ download the following:
actor_2010q4a.sql.gz
toxrefdb_2010q1b.sql.gz
toxminer_v17.sql.gz
actor.war
toxrefdb.war

*****Decompress the data

gunzip 	actor_2010q4a.sql.gz
gunzip 	toxrefdb_2010q1b.sql.gz
gunzip 	toxminer_v17.sql.gz

*****Load the data

mysql -u my_actor_user actor_2010q4a -pmy_actor_pass < actor_2010q4a.sql
mysql -u my_actor_user toxrefdb_2010q1b -pmy_actor_pass < toxrefdb_2010q1b.sql
mysql -u my_actor_user toxminer_v17 -pmy_actor_pass < toxminer_v17.sql


*****Install ACToR & ToxRefDB Interfaces

place the war files,actor.war and toxrefdb.war, in the webapps/ directory of your Tomcat installation.
Starting the Tomcat server will cause the actor.war to be expanded. It will 
result in the creation of a webapps/actor directory. Edit the 
webapps/actor/WEB-INF/classes/jdbc.properties and
webapps/toxrefdb/WEB-INF/classes/jdbc.properties 
files as follows:
every occurrence of "my_actor_user" should be replaced with the user name you used when creating your database
every occurrence of "my_actor_pass" should be replaced with the user password you used when creating your database
every occurrence of "134.67.216.49" should be replaced with the IP address of your database server

Your jdbc.properties files should be similar to the following:

jdbc.toxrefdb.url=jdbc:mysql://134.67.216.49/toxrefdb_2010q1b
jdbc.toxrefdb.username=my_actor_user
jdbc.toxrefdb.password=my_actor_pass
jdbc.toxrefdb.initialSize=2
jdbc.toxrefdb.maxActive=30
jdbc.toxrefdb.validationQuery=select * from tbl_study_general_info limit 1
jdbc.toxrefdb.testOnBorrow=false
jdbc.toxrefdb.testWhileIdle=true
jdbc.toxrefdb.timeBetweenEvictionRunsMillis=120000
jdbc.toxrefdb.numTestsPerEvictionRun=5

jdbc.actor.url=jdbc:mysql://134.67.216.49/actor_2010q4a
jdbc.actor.username=my_actor_user
jdbc.actor.password=my_actor_pass
jdbc.actor.initialSize=2
jdbc.actor.maxActive=30
jdbc.actor.validationQuery=select data_collection_id from data_collection limit 1
jdbc.actor.testOnBorrow=false
jdbc.actor.testWhileIdle=true
jdbc.actor.timeBetweenEvictionRunsMillis=120000
jdbc.actor.numTestsPerEvictionRun=5

jdbc.toxminer.url=jdbc:mysql://134.67.216.49/toxminer_v17
jdbc.toxminer.username=my_actor_user
jdbc.toxminer.password=my_actor_pass
jdbc.toxminer.initialSize=2
jdbc.toxminer.maxActive=10
jdbc.toxminer.validationQuery=select * from data_collection limit 1
jdbc.toxminer.testOnBorrow=false
jdbc.toxminer.testWhileIdle=true
jdbc.toxminer.timeBetweenEvictionRunsMillis=120000
jdbc.toxminer.numTestsPerEvictionRun=5


After restarting the Tomcat server, ACToR should be accessible via
http://localhost:8080/actor
depending on the port specified in Tomcat/conf/server.xml
