IS-InformationCollector

IS-Registry

Installation

The IS-Registry can be deployed on a gHN as any other gCube Service by typing:

gcore-deploy-service <path>/org.gcube.informationsystem.registry.gar

gHN Configuration

The gHN where an IS-Registry instance is running has to be configured in a special way:

1. it must be declared a STATIC node, i.e. a node where no dynamic deployment activities can be performed
2. it must run in a ROOT mode, meaning that it starts up in a special way

These two configuration settings have to be specified in the $GLOBUS_LOCATION/config/GHNConfig.xml file as reported in the following example:

<?xml version="1.0" encoding="UTF-8"?>
<jndiConfig xmlns="http://wsrf.globus.org/jndi/config">

                        value="false"
                        type="java.lang.Boolean"

                        override="false" />
  
    </global>
</jndiConfig>

Instance Configuration

The configuration of an IS-Registry instance is a two-step process:

• since a IS-Registry can act in one and only one scope, its JNDI file ($GLOBUS_LOCATION/etc/org.gcube.informationsystem.registry/jndi-config.xml) must be configure to join only one scope. In the following example, the instance is configure to join the scope named /testing/vo1:

<?xml version="1.0" encoding="UTF-8"?>
<jndiConfig xmlns="http://wsrf.globus.org/jndi/config">

<service name="gcube/informationsystem/registry">
        
                <environment 
                        name="configDir" 
                        value="etc/org.gcube.informationsystem.registry" 
                        type="java.lang.String"
                        override="false" />
                
                <environment 
                        name="securityManagerClass" 
                        value="org.gcube.common.core.security.GCUBESimpleServiceSecurityManager" 
                        type="java.lang.String"
                        override="false" />
                
                <!-- Lifetime for temporary resources, after this period temporary resources are destroyed-->
                <environment
                        name="temporaryResourceLifetimeInMs"
                        value="480000"
                        type="java.lang.Long"
                        override="false" />     
                                
                                        
                         
                <environment 
                        name="startScopes" 
                        value=" /testing/vo1" 
                        type="java.lang.String"
                       override="false" />         
                        
</service>
....

• due to its role, the IS-Registry requires a special Service Map for its scope. In that map, the EPR of the RegistryFactory of itself must be reported. Let's suppose that an instance running on a node named grid5.4dsoft.hu joins the /testing/vo1 scope, the $GLOBUS_LOCATION/config/ServiceMap_vo1.xml file must be filled as follows (the EPRs are here just for the sample purposes):

<ServiceMap>
        <Service name ="ISICAllQueryPT" endpoint ="http://grid1.4dsoft.hu:8080/wsrf/services/diligentproject/informationservice/disic/DISICService"/>
        <Service name ="ISICAllRegistrationPT" endpoint ="http://grid1.4dsoft.hu:8080/wsrf/services/diligentproject/informationservice/disic/DISICRegistrationService"/>                        
        <Service name ="ISRegistry" endpoint="http://grid5.4dsoft.hu:8080/wsrf/services/gcube/informationsystem/registry/RegistryFactory" />
</ServiceMap>
