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:
- it must be declared a STATIC node (GHNtype parameter), i.e. a node where no dynamic deployment activities can be performed
- it must run in a ROOT mode (mode parameter), meaning that it starts up in a special way
These two configuration settings have to be specified in the $GLOBUS_LOCATION/config/GHNConfig.xml file as reported in the following example:
<?xml version="1.0" encoding="UTF-8"?> <jndiConfig xmlns="http://wsrf.globus.org/jndi/config"> <global> <environment name="securityenabled" value="false" type="java.lang.Boolean" override="false" /> <!-- setting for ROOT mode --> <environment name="mode" value="ROOT" type="java.lang.String" override="false" /> <environment name="startScopes" value="devsec" type="java.lang.String" override="false" /> <environment name="infrastructure" value="gcube" type="java.lang.String" override="false" /> <environment name="labels" value="GHNLabels.xml" type="java.lang.String" override="false" /> <!-- setting for STATIC gHN --> <environment name="GHNtype" value="STATIC" type="java.lang.String" override="false" /> <environment name="localProxy" value="/home/globus/..." type="java.lang.String" override="false" /> <environment name="coordinates" value="43.719627,10.421626" type="java.lang.String" override="false" /> <environment name="country" value="it" type="java.lang.String" override="false" /> <environment name="location" value="Pisa" type="java.lang.String" override="false" /> <environment name="updateInterval" value="60" type="java.lang.Long" override="false" /> </global> </jndiConfig>
Instance Configuration
The configuration of an IS-Registry instance is a two-step process:
- since an IS-Registry can act in one and only one scope, its JNDI file ($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 configured 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 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 reported EPRs are just for 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>
Verify the installation
Once the IS-Registry has been configure, the gHN can be [started] and the nohup.out file has to report (among the others) the following portTypes:
gHN started at: http://host:port/wsrf/services/ with the following services: GCUBE SERVICES: ... [4]: http://host:port/wsrf/services/gcube/informationsystem/registry/Registry [5]: http://host:port/wsrf/services/gcube/informationsystem/registry/RegistryFactory
