International workshop on Météo-France and UK Met Office vGISC implementation OpenWIS installation and requirements for NC / DCPC 5 th June to 7 th June 2013

NC (minimum) Existing GTS flow Web Access to VGISC portal

DCpc Telecom harness Dissemination harness

dcPC Data source harness Dissemination harness

System Requirements RedHat x86_64 (official) or CentOS Versions 5.5 to 5.8 English language (required by OpenAM installer)

Architecture Modules: –Portals: User & Admin with embedded MD service –Database –LDAP & SSO Server –User Management –Data Service –Harnesses: DataSource + Dissemination + MSS –Staging Post –Indexing Service (SolR)

Software The OpenWIS software architecture is composed of the following elements: Sun JDK 1.6u21 Tomcat JBoss EAP 5.1 OpenDS OpenAM release9 Apache Solr 1.4.1

Proposed Configuration Compact configuration: –2 servers: front-end and back-end Front-end server: –WISPortal module (can be Virtualized) One ‘WIS Portal’ module grouping an Apache server (HTTP Front-end) and the OpenWIS® User Portal (Web portal running on Tomcat). –WISSecurity (can be Virtualized) One ‘WIS Security’ module hosting the authentication server (OpenAM running on JBoss).

Proposed Configuration Back-end server: –WISAdmin module (can be Virtualized) One ‘WIS Administration’ module hosting the OpenWIS® Administration portal (Web portal running on Tomcat). –WISData module (can be Virtualized) One ‘WIS Data’ module hosting the database (Postgres), the Data service (running on JBoss) and the harnesses: dissemination harness (data dissemination through FTP or ) and the harness to the local data sources.

Technical Requirements Front-end server RequirementMinimumRecommended CPU1 (2.4 GHz Quad core) 2 (2.4 GHz Quad core) RAM8GB Hard Disk200 GB / HDD 7200 rpm

Technical Requirements Back-end server Monitoring station –HP 7400 or equivalent RequirementMinimumRecommended CPU1 (2.4 GHz Quad core) 2 (2.4 GHz Quad core) RAM8GB16GB Hard Disk500 GB / HDD 7200 rpm 1TB

Network Both servers must have an access to the internet. OpenWIS requires a public domain and sub-domains. For instance, if the main site URL is the user portal will be addressed as follows: –

Network The OpenSSO security module must have a public URL as well: – The Administration Portal must be able to establish HTTP connections with a remote GISC centre for meta-data harvesting.

Network Front-end apache server manages the following HTTP redirections : –Administration Portal URLs redirected towards the tomcat server installed on back- end server –User Portal URLs redirected towards the tomcat server installed on front-end server –OpenSSO URLs redirected towards the JBOSS server installed on front-end server

System Requirements

Interfaces with the local systems Interfaces needed to communicate with the local systems Acquisition systems (MSS) Dissemination systems Local data sources (Data Bases)

Local requests are for locally Cached or locally produced data, on an ad-hoc basis or as a recurrent subscription. Local products can be retrieved via the interfaces to local data sources: archive or product creation system. Local data source harness

Implementation of harness Web services to Interface with existing data source (dcPC) Sub-selection parameters for Local Data Source Allows selection of product instance from metadata for request/subscribe Local Data Source product access Give access to local data source products ( extraction ) Check availability of new products (for subscribers)

Telecom harness

Mainly for DCpc and GISC No special development needed for Data collection (GTS→ OpenWIS) Data feeding (OpenWIS → GTS) Implementation of harness Web services MSS/FSS subscriptions management Get list of available channels for a user Create/Update routing of product Monitor data flow (routings)

Requested data are delivered via the software interface to the local dissemination system. Dissemination harness

Implementation of harness Web services to Interface with existing dissemination tool (DCpc and dcPC) Allow dissemination of product instances to the user By FTP or Asynchronously Two interfaces can be configured Public or RMDCN dissemination tool

Manage failover High availability through Heartbeat and either a shared DRBD partition SAN/NAS solution

Staffing Administrator of the WIS System –Advanced skills of Unix operating system administration –Good knowledge of OpenWIS distributed architecture + WIS concepts Operators of the WIS System –WIS Concepts (harvesting/OAIPMH) –Basic skills on Unix Metadata editors –Basic knowledge of ISO (WMO Core Profile)
