Contents

This part of the guide is intended to cover the installation and configuration of gCube services that are not mentioned in the Administration guide. Mainly we refer to services that are not Enabling and that can be installed dynamically by the Infrastructure/VO Managers. The list includes also for each component known issues and specific configuration steps to follow.

Search

Search V 2.xx

The installation of a Search Node in gCube is characterised by the installation of 2 web-services ( in the minimal configuration ) :

  • SearchSystemService
  • ExecutionEngineService

This is the minimal installation scenario but it's possible to enable distributed search as well and this will required the installation and configuration of several ExecutionEngineServices

HW requirements

The minimal installation requirements for a Search node are a Single CPU node with 2GB RAMm but it's more than recommended to have at least 3GB RAM on the node dedicated to the GHN.

Configuration

The SearchSystemService and ExecutionEngineService have to be automatically/manually deployed in a VRE scope. In addition if we want to configure the SearchSystemService to exploit the local ExecutionEngineService to run the queries ( minimal installation) we should configure the jndi service as follows:

  • excludeLocal = false
  • collocationThreshold = 0.3f
  • complexPlanNumNodes = 800000

Search v 3.x.x

The 3.0 version has moved to Smartgears and tomcat.

The requirement of the codeployment with Execution Engine Service is also there , so the Execution Engine Service v 2.0.0 has been also ported to SmartGears

HW requirements

The minimal installation requirements for a Search node are a Single CPU node with 2GB RAMm but it's more than recommended to have at least 3GB RAM on the node dedicated to the GHN.

Configuration

in order to fix an issue with datanucleus compatibility and java 7 there is a change to be included in the tomcat configuration:

  • uncomment and modify the following line on the $CATALINA_HOME/bin/catalina.sh file:
JAVA_OPTS="$JAVA_OPTS -noverify -Dorg.apache.catalina.security.SecurityListener.UMASK=`umask`"
  • The conf file $CATALINA_HOME/conf/infrastructure.properties containing infra and scope informations needs to be present
# a single infrastructure
infrastructure=d4science.research-infrastructures.eu
 # multiple scopes must be separated by a common (e.g FARM,gCubeApps)
scopes=Ecosystem
clientMode=false


  • The conf file $CATALINA_HOME/webapps/<search>WEB-INF/classes/deploy.properties needs to be filled with this info:
hostname = xx
startScopes = xx
port=xx

Known Issues

Excecution Engine

The 2.0 version has moved to Smartgears and tomcat.

HW requirements

The minimal installation requirements for an Execution Engine node are a Single CPU node with 2GB RAMm but it's more than recommended to have at least 3GB RAM on the node dedicated to the GHN.

Installation

Different packagings of the Execution engine are available depending on the service they are going to be co-deployed with and invoked:

  • DTS : <artifactId>executionengineservice-dts</artifactId>
  • Search: <artifactId>executionengineservice-search</artifactId>

Configuration

in order to fix an issue with datanucleus compatibility and java 7 there is a change to be included in the tomcat configuration:

  • uncomment and modify the following line on the $CATALINA_HOME/bin/catalina.sh file:
JAVA_OPTS="$JAVA_OPTS -noverify -Dorg.apache.catalina.security.SecurityListener.UMASK=`umask`"
  • The conf file $CATALINA_HOME/conf/infrastructure.properties containing infra and scope informations needs to be present
# a single infrastructure
infrastructure=d4science.research-infrastructures.eu
 # multiple scopes must be separated by a common (e.g FARM,gCubeApps)
scopes=Ecosystem
clientMode=false


  • The conf file $CATALINA_HOME/webapps/<execution-engine>WEB-INF/classes/deploy.properties needs to be filled with this info:
hostname = xx
startScopes = xx
port=xx
pe2ng.port = 4000
  • in case the exeucution engine needs to call DTS on the container.xml add:
<property name='dts.execution' value='true' />

Executor and GenericWorker

HW requirements

The minimal installation requirements for an Executor node with a Generic Worker plugin are a Single CPU node with 2GB RAM but it's more than recommended to have at least 3GB RAM on the node dedicated to the GHN.

Configuration

The following Software should be installed on the VM:

  • R version 2.14.1

whit the following components

  • coda
  • R2jags
  • R2WinBUGS
  • rjags
  • bayesmix
  • runjags

Known Issues

  • The GenericWorker is exploited by the Statistical Manager service to run distributed computations. Given that the SM use the root scope to discover instances of the GenericWorker. the plugin must be deployed at root scope level
  • Given that the GenericWorker plugin depends on the Executor Service, when dynamically deploying the plugin the Executor Service is also deployed.


SmartExecutor

HW requirements

The minimal installation requirements for an Executor node with a Generic Worker plugin are a Single CPU node with 2GB RAM but it's more than recommended to have at least 3GB RAM on the node dedicated to the vHN (Smartgears gHN).

Configuration

No specific configuration are needed for SmartExecutor

Known Issues

  • When correctly started the SmartExecutor publishes a ServiceEndpoint with <Category>VREManagement</Category> and <Name>SmartExecutor</Name>. You can check the availability of the plugin on that resource. there is one <AccessPoint> per plugin.


SmartGenericWorker

HW requirements

The minimal installation requirements for an Executor node with a Generic Worker plugin are a Single CPU node with 2GB RAM but it's more than recommended to have at least 3GB RAM on the node dedicated to the vHN.

Configuration

The following Software should be installed on the VM:

  • R version 2.14.1

whit the following components

  • coda
  • R2jags
  • R2WinBUGS
  • rjags
  • bayesmix
  • runjags

Known Issues

  • The SmartGenericWorker is exploited by the Statistical Manager service to run distributed computations. Given that the SM use the root scope to discover instances of the SmartGenericWorker, the plugin must be deployed at root scope level
  • To deploy SmartGenericWorker you need to copy the SmartGenericWorker jar-with-dependecies in $CATALINA_HOME/webapps/smart-executor/WEB-INF/lib/ directory. A container restart is needed to load the new plugin.
  • When the container is restarted the plugin availability can be cheeked looking at the Service Endpoint published by the SmartExecutor.

This simple script can help the deployment process.


#!/bin/bash $CATALINA_HOME/bin/shutdown.sh -force rm -rf $CATALINA_HOME/webapps/smart-executor*

cp ~/smart-executor.war $CATALINA_HOME/webapps/

mkdir $CATALINA_HOME/webapps/smart-executor unzip $CATALINA_HOME/webapps/smart-executor.war -d $CATALINA_HOME/webapps/smart-executor

cp ~/smart-generic-worker-*.jar $CATALINA_HOME/webapps/smart-executor/WEB-INF/lib/

sleep 5s $CATALINA_HOME/bin/startup.sh

DTS

DTS v2.x

HW requirements

The minimal installation requirements for an DTS node are a Single CPU node with 2GB RAMm but it's more than recommended to have at least 3GB RAM on the node dedicated to the GHN.

Configuration

DTS uses Execution Engine to run the transformations so at least one Execution Engine should be deployed in the same scope as DTS and the related GHNLabels.xml file should contain: 

<Variable>
      <Key>dts.execution</Key>
      <Value>true</Value>
</Variable>

Known Issues

none

DTS v3.x

HW requirements

The minimal installation requirements for an DTS node with a Generic Worker plugin are a Single CPU node with 2GB RAMm but it's more than recommended to have at least 3GB RAM on the node dedicated to the GHN.

Configuration

  • The conf file $CATALINA_HOME/conf/infrastructure.properties containing infra and scope informations needs to be present
# a single infrastructure
infrastructure=d4science.research-infrastructures.eu
 # multiple scopes must be separated by a common (e.g FARM,gCubeApps)
scopes=Ecosystem
clientMode=false
  • The conf file $CATALINA_HOME/webapps/<dts>/WEB-INF/classes/deploy.properties needs to be filled with this info:
hostname = xx
startScopes = xx
port=xx

DTS uses Execution Engine to run the transformations so at least one Execution Engine should be deployed in the same scope as DTS and the related Smartgears conf file ( container.xml ) should have this properties: 

<property name='dts.execution' value='true' />

Index

Index Service

The Index Service is the latest released Restful Service running on Smartgears. It implements both FW and FT index functionalitoes

HW requirements

Given codeployment with ElasticSearch ( embedded) it's recommended at least a VM with 4GB RAM and 2 CPUs.

Also open file limit should be raised to 32000

Configuration

Details on the Index Service configuration are available at https://gcube.wiki.gcube-system.org/gcube/index.php/Index_Management_Framework#Deployment_Instructions

ForwardIndexNode ( Dismissed)

The ForwardIndexNode service needs to be codeployed with an instance of CouchBase service

HW requirements

Given codeployment with Couchbase it's recommended at least a VM with 4GB RAM and 2 CPUs.

Configuration

The installation of Couchbase should be performed manually and it depends on the OS ( binary package, rpm, debs).

It's recommended to put an higher limit of the open files on the VM ( 32000 min).

The configuration for the FWIndexNode that should be customized (jndi file):

  • couchBaseIP = IP of the server hosting Couchbase ( so the same as the GHN)
  • couchBaseUseName = the username set when configuring Couchbase
  • couchBasePassword = the password set when configuring Couchbase

Once configured it's needed to initialize Couchbase using the cb_initialize_node.sh script contained into the service configuration folder.

Known Issues

  • Sometimes the cb_initialize_node.sh script fails, it could mean that there is not enough memory to inizialize the data bucket , try to reduce the value of ramQuota in the jndi file.

Known Issues

Tested on ghn 4.0.0 and StatisticalManager service 1.4.0:

  • install the SM on the same network where the database and the used resources are located. Otherwise it would imply to restart production databases because direct access could not be granted to such resources.
  • remove lib axis-1.4.jar from gCore/lib
  • replace the library hsqldb-1.8.jar with the library hsqldb-2.2.8.jar in gCore/lib

Additional Installation Steps

  • create a suitable R environment[1]
  • download the file following file gebco under /home/gcube/gCore/etc/statistical-manager-service-full-XXX/cfg and rename it as gebco_08.nc
  • copy the gcube keys under /home/gcube/gCore/etc/statistical-manager-service-full-XXX/cfg/PARALLEL_PROCESSING

TESTING

Test plan for the Statistical Manager.

GIS Technologies

In order to handle GIS Technologies, developers should rely on libraries geonetwork and gisinterface. Both distributed under subsystem org.gcube.spatial.data. Depending on which libraries are used, different resources are mandatory.

Geonetwork

This sections covers the default behavior of geonetwork library. Please note that clients of the library might override it.

Geonetwork Service Discovery

A single Service Endpoint per Geonetwork instance is needed, you can find more details on the resource here.

Metadata Publication

In order to exploit the library's features to generate ISO metadata, the following Generic Resource is needed in the scope :

  • Secondary Type : ISO
  • Name : MetadataConstants

Metadata Resolution

Geonetwork library uses the "Uri Resolver Manager" library to resolve the Gis Layer generated via HTTP protocol, the following Generic Resource is needed in the scope:

  • Uri Resolver Manager

https://gcube.wiki.gcube-system.org/gcube/URI_Resolver#Uri_Resolver_Manager 

<Type>GenericResource</Type>
<SecondaryType>UriResolverMap</SecondaryType>
<Name>Uri-Resolver-Map</Name>

GeoServer

In order to let gisinterface library discover instances of Geoserver, an Access Point must be defined for each instance. The Service Endpoint resource for such Access Points must have :

  • Category : Gis
  • Platform/Name : GeoServer

GeoExplorer

In order to let GeoExplorer portlet work fine, you must copy the resources following from root scope (/d4science.research-infrastructures.eu/) to the VRE where it must run:

  • Transect
<Type>RuntimeResource</Type>
<Caegory>Application</Category>
<Name>Transect</Name>
  • Gis Resolver

https://gcube.wiki.gcube-system.org/gcube/URI_Resolver#GIS_Resolver 

<Type>RuntimeResource</Type>
<Category>Service</Category>
<Name>Gis-Resolver</Name>
  • Gis Viewer Application
<Type>GenericResource</Type>
<SecondaryType>ApplicationProfile</SecondaryType>
<Name>Gis Viewer Application</Name>

and then must edit the Generic Reosurce shown here: https://gcube.wiki.gcube-system.org/gcube/URI_Resolver#Generic_Resource_for_Gis_Viewer_Application

Tabular Data Manager

Each service's operation may need a specific configuration. The following is a list of needed resources per operation module.

Operation View

The module requires GIS Technologies to be already configured in the operating scope. See Gis Technologies.

The module requires also the following Generic Resource :

  • Secondary Type : TDMConfiguration

Since the operation needs to put data in a postgis database already connected with Geoserver, a Service Endpoint for such database must be present in the same scope. Constraints for retrieving such Service Endpoint are taken from the Generic Resource described above (values are indicated with their xml Element name as declared in the Generic Resource's body) :

  • Category : <gisDBCategory>
  • Platform/Name : <gisDBPlatformName>
  • AccessPoint/<tdmDataStoreFlag> : true

Resource Catalogue

In this section the resources required to deploy the Catalogue in a given context are reported.

Please note that only the mandatory ones are shown.

CKAN Connector

ServiceClass = DataAccess
ServiceName = CkanConnector

This is the service that allows to perform login operation from the Gateways on CKAN. It runs on SmartGears so once it is published in the context there is no much left to do. However, it is fundamental.

Generic Resource

CKan to Zenodo Mappings

A set of generic resources with SecondaryType = Ckan-Zenodo-Mappings is expected in order to enable the upload to Zenodo. Since each of these generic resources maps a precise CKAN item profile, The required set may vary depending on the VRE. The user requesting the VRE creation is expected to specify the minimum set of these resources to be registered in the context.

CkanPortlet: this is the Portlet URL

SecondaryType = ApplicationProfile
Name = CkanPortlet
Description = The url of the gcube-ckan-datacatalog portlet for this scope

The content (body) of the resource has to report the url of the catalogue portlet for this context (VRE), e.g. 

<url>https://services.research-infrastructures.eu/group/d4science-services-gateway/data-catalogue</url>

(Item) Catalogue

SecondaryType = ApplicationProfile
Name = Catalogue (old "Item Catalogue")
Description = This is the Item Catalogue application profile for alerting items creation in the infrastructure's catalogues

This resource is deployed at root level. It contains a list of endpoints in the following format 

<EndPoint>
<URL>....</URL>
<Scope>....</Scope>
</EndPoint>

Each couple shows the map between a context and the url where the portlet is deployed in that context.

NOTE: the resource is automatically updated by the portal (since gCube 4.11).

Catalogue-Resolver

SecondaryType = ApplicationProfile
Name = Catalogue-Resolver
Description = Used by Catalogue Resolver for mapping VRE NAME with its SCOPE so that resolve correctly URL of kind: 
              https://[CATALOGUE_RESOLVER_SERVLET]/[VRE_NAME]/[entity_context value]/[entity_name value]

See wiki page at: CATALOGUE_Resolver

NOTE: the resource is automatically updated by the Catalogue Resolver

DataCatalogueMapScopesUrls

SecondaryType = ApplicationProfile
Name = DataCatalogueMapScopesUrls
Description = EndPoints that map url to scope for the data catalogue portlet instances

This resource is deployed at root level. It contains a list of "exceptions", i.e. how to manage catalogues at VO or root VO level.

DataCatalogueNamespace

SecondaryType = DataCatalogueNamespace
Name = Namespaces Catalogue Categories
Description = This resource defines namespaces for the catalogue categories

This resource has been created at root level. To allow gcat to properly works must be added into every scopes where is present gcat.

Catalogue

Update this configuration at ROOT VO level. It is used by Publishing Widget 

SecondaryType = ApplicationProfile
Name = Catalogue
Description = This is the Item Catalogue application profile for alerting items creation in the infrastructure catalogues
<Body><AppId>org.gcube.datacatalogue.ProductCatalogue</AppId>...

The above Generic Resource stored at ROOT VO level must be updated by adding an entry of kind: 

<EndPoint>
	<Scope>[THE SCOPE]</Scope>
	<URL>[THE PORTLET URL TO THE GATEWAY IN ACT FOR THE SCOPE]</URL>
</EndPoint>

e.g. for /d4science.research-infrastructures.eu/D4OS/EOSCPillarServiceRegistry 

<EndPoint>
    <Scope>/d4science.research-infrastructures.eu/D4OS/EOSCPillarServiceRegistry</Scope>
    <URL>https://eosc-pillar.d4science.org/group/eoscpillarserviceregistry/catalogue</URL>
</EndPoint>

for the SCOPE where the Catalogue has been added

Catalogue

Update this configuration at ROOT VO level. It is used by gCAT 

SecondaryType = ApplicationProfile
Name = Catalogue
Description = This is the Item Catalogue application profile for alerting items creation in the infrastructure catalogues
<Body><AppId>gCat</AppId>...

The above Generic Resource stored at ROOT VO level must be updated by adding an entry of kind: 

<EndPoint>
	<Scope>[THE SCOPE]</Scope>
	<URL>[THE PORTLET URL TO THE GATEWAY IN ACT FOR THE SCOPE]</URL>
</EndPoint>

e.g. for /d4science.research-infrastructures.eu/D4OS/EOSCPillarServiceRegistry 

<EndPoint>
    <Scope>/d4science.research-infrastructures.eu/D4OS/EOSCPillarServiceRegistry</Scope>
    <URL>https://eosc-pillar.d4science.org/group/eoscpillarserviceregistry/catalogue</URL>
</EndPoint>

for the SCOPE where the gCAT has been added

Catalogue Badge

Update the following GR at ROOT VO level. It is used by Catalogue Badge 

SecondaryType = ApplicationProfile
Name = DataCatalogueMapScopesUrls
Description = EndPoints that map url to scope for the data catalogue portlet instances

You need to add an entry of kind: 

<EndPoint>
	<Scope>[THE SCOPE]</Scope>
	<URL>https://[GATEWAY-HOSTNAME]/group/[GATEWAY-NAME]-gateway</URL>
</EndPoint>

e.g. for /d4science.research-infrastructures.eu/SoBigData/TerritoriAperti 

<EndPoint>
   <Scope>/d4science.research-infrastructures.eu/SoBigData/TerritoriAperti</Scope>
   <URL>https://territoriaperti.d4science.org/group/territoriaperti-gateway</URL>
</EndPoint>

you need to add the above entries for the Gateway https://territoriaperti.d4science.org where the Catalogue Badge is in action

The URL https://territoriaperti.d4science.org/group/territoriaperti-gateway is built and used by ckan-util-library to get the VRE SCOPE (i.e. /d4science.research-infrastructures.eu/SoBigData/TerritoriAperti) 

String clientURL = gatewaySiteURL+siteLandingPage;
String appPerScopeURL = ApplicationProfileScopePerUrlReader.getScopePerUrl(clientURL);

needed to discover at VRE level the property `SOLR_INDEX_ADDRESS` stored into SeviceEndpoint `CKanDataCatalogue`

Service Endpoint(s)

Zenodo API

Category = Repository
Platform.Name = Zenodo

A service endpoint defining the Zenodo API address and credentials is expected in order to enable the "Upload to Zenodo" feature. Credentials may vary depending on the context.

CKanDataCatalogue

Category = Application
Name = CKanDataCatalogue
Description = A Tomcat Server hosting the ckan data catalogue

Among the other properties of the SE, these should be reported:

  • HostedOn (in RunTime) is the url of the ckan instance, e.g. ckan-d4s.d4science.org;
  • Username (in AccessData) is the username of the CKAN SYSAdmin;
  • Property URL_RESOLVER, whose value is equal to the url of the URI-RESOLVER in the context;
  • Encrypted property API_KEY, is the api key of the CKAN SYSAdmin;
  • SOCIAL_POST: (true/false) instruct gCat to create the social post in the VRE. If this property is not present it is assumed as false. The value can be overrided by the gCat client on the item creation request.
  • ALERT_USERS_ON_POST_CREATION: isntrcut gCat to request to social service if notify users about the generated social post. If this property is not present it is assumed as false.

CKanDatabase

Category = Database
Name = CKanDatabase
Description = A Postgres Server hosting the ckan database

Among the other properties of the SE, these should be reported:

  • HostedOn (in RunTime) is the machine hosting the postgres CKAN uses (e.g. ckan-pg-d4s.d4science.org);
  • EndPoint (in AccessPoint) is the machine URL hosting the postgres CKAN uses followed by the port number (e.g., ckan-pg-d4s.d4science.org:5432);
  • In AccessData please report the credentials (password must be encrypted) of the user allowed to access the database.


Please note that gCat requires to dial with postgres, hence the gCat host must be enabled on postgres installation

Enable view per VRE

In order to enable this special view (which allows the catalogue portlet to render itself on a single organization), one should access the portal and as administrator enable a special custom field of the VRE. The custom field can be found, on the VRE Page, under "Admin > Pages > Configuration > Site Settings > Custom Field". Set it to true to enable the view.

News Feed & Catalogue

When you have added all GR/RR to serve a VRE with an instance of D4Science Catalogue, in order to be able to publish social posts via Social Networking Library must be added an entry of kind: 

<EndPoint>
	<Scope>[THE SCOPE]</Scope>
	<URL>[THE RELATIVE URL OF SCOPE SAVED IN THE GATEWAY]</URL>
</EndPoint>

e.g. 

<EndPoint>
   <Scope>/d4science.research-infrastructures.eu/D4OS/EOSCPillarServiceRegistry</Scope>
   <URL>/group/eoscpillarserviceregistry</URL>
</EndPoint>

into the following Generic Resource: 

SecondaryType = ApplicationProfile
Name = News Feed

published at ROOT VO level.

News Feed & gCat

see at: DataCatalogueNamespace

Accounting Dashboard & Catalogue

see the wiki page at Add_Google_Analytics_to_the_Accounting_Dashboard

SocialNetworking service

see the wiki page at Social Networking Library

Known Issues

The socialnetworking service must be restarted when liferay is up

GFeed

The following is a list of minimal requirements for the execution of gFeed Service.

  • Database : the service needs a dedicated DB for its logic and looks in the current context for a DB registered as Service Endpoint with
    • Category : Database
    • Name : Feeder_DB
  • Common configuration : the service loads default plugins configurations from the IS by lookig for a Generic Resource registered as
    • Secondary type : configuration
    • Name : gcat-feeder

The following parameters need to be customized for every context in which the resource is pubilshed :

Please keep in mind that depending on deployed plugins these requirements may not be enough.

GeoPortal

The following instructions are meant in order to configure the "Geoportale Nazionale per l'Archeologia".

Service Endpoints

The library needs access to a postgres DB looking for the following SE parameters (e.g. b655ddab-907a-4390-82a7-bc394535dcbc in preproduction environment):

  • Profile/Category : Database
  • Profile/Platform/Name : postgresql
  • Profile/AccessPoint//Property/Name : GNA_DB
  • Profile/AccessPoint//Property/Value : internal-db

The library needs access to a postgis DB looking for the following SE parameters (e.g. e8c3d172-fb15-446c-9a73-593625414b93 in preproduction environment):

  • Profile/Category : Database
  • Profile/Platform/Name : postgis
  • Profile/AccessPoint//Property/Name : GNA_DB
  • Profile/AccessPoint//Property/Value : Concessioni


The SE with the following coordinate has to be added in the proper VRE: 

<Category>Service</Category>
<Name>HTTP-URL-Shortener-DL</Name>

Generic Resources

1. The Generic Resources with 

<SecondaryType>GeoNaMetadata</SecondaryType>

have to be copied in the proper VRE. They are used by 'GeoNa-Data-Entry' portlet to build dynamically the web-forms for data entries.

2. The Generic Resource with the following coordinates: 

   <SecondaryType>ApplicationProfile</SecondaryType>
   <Name>GeoNa-Viewer-Profile</Name>

   /*having in the body the following AppId*/

   <AppId>geoportal-data-viewer-app</AppId>

has to be copied in the proper VRE. Used by 'GeoNa-Data-Entry' and 'GeoNa-Data-Viewer' portlets to discover common info like portlet URLs in the VRE, layers and so on.

Resolvers

These are the resources that must be updated when changing the URI-Resolver balancer and/or its hostname:
