Configuration of CVRG LDDMM Portal

Configuration Steps for Portal/LDDMM/GWiz/SRB

Configuring LDDMM/GWiz Daemon for a Grid Portal Job Submission

1) set GWIZ_HOME to install location of <GWIZ_HOME>/lddmm/conf

2) Open gwiz-config.xml in an editor

3) Edit and change the jdbc properties. This jdbc postgresql host should be the CVRG portal where the database is installed.

<value>jdbc:postgresql://[portal_host-example]/[postgres-database-name-example]</value>

<name>username</name>

<value>[databse-username-example]</value>

<name>password</name>

<value>[database-password-example]</value>

</properties>Storage Resource Broker version 3.4.2

4)Open the cluster.xml using an editor

5)Update the environment variable for SRB connection

<name>environment</name>

<value>X509_USER_PROXY=x509up;LDDMM_HOME=[location-of-JHU-lLDDMM-script];SERVER_DN=[PUT-SRB-SERVER-DN-HERE];AUTH_SCHEME=GSI_AUTH;mdasDomainName=[JHU-SRB-DOMAIN];mdasDomainHome=[JHU-SRB-DOMAIN];srbHost=[JHU-SRB-HOST-GOES-HERE];srbPort=[SRB-PORT];defaultResource=[JHU-SRB-DEFAULT-RESOURCE]</value>

Configuration of Portal to Identity Provider

1) Edit the /etc/hosts file of Portal server

Add ip-host name mapping for faster domain name resolution

Configuring Portal and LDDMM Host Communication

1) Update the Portal Server’s IP Tables Entry

Open /etc/sysconfig/iptables and add postgres database port to accept tcp and udp connection
For cor001.icm.jhu.edu (128.220.138.35) where the GridWizard 1.0 (GWiz)/LDDMM 1.0 will be running from we add an entry so that the it has access to the Portal hosts Postgres database.

2) Edit the Postgres pg_hba.conf

cd [Postgres HOME]/pgsql/data
Edit and add entry in pg_hba.conf file for host accessing Postgres database in the Portal server.
Specify the type, database, db user, ip address of host that needs access, and authentication method. 128.220.138.35 is cor001.icm.jhu.edu which needs access to the Postgres database in the Gridsphere portal.
