Architectural Overview

Architectural Overview• GreenVulcano ESB is made of 4 layers

Virtual Layer Core Layer Connectivity Layer Administration and Monitoring

Virtual Layer

• Provides the independence by any specific J2EE Application Server– Makes no use of any proprietary mechanism of any App.Server– Performs “virtual” operation implemented by the Core Layer

• Dequeue• Enqueue

• Separates the business analysis from the implementation and software configuration

– The business analyst can create the business flow through the graphical editor console

– The technical specialist implements the flow through the administration console

• Forward• Call

*Enterprise version only

Core Layer• It’s the engine of the ESB

– Drives the framework – Performs the services needed to implement the business flows– Internal micro-workflows– Data-dependent (intelligent) routing– Dispatching– Data encryption– Data transformation– Data compression & decompression– Store and forwarding– Business flows / statistics– Service level caching– Run time use of Java objects through OGNL language

• Object-Graph Navigation Language; it is an expression language for getting and setting properties of Java objects

Connectivity Layer

• Provides the connectivity with the external systems

• Plug-in architecture– Any new JCA connector can be easily

plugged in at Run-time

• Client libraries are provided to external systems or applications to invoke Services

– EBJ (Enterprise Bus Java client library)E– EBC (Enterprise Bus C++ client library)E

Connectivity Layer

– SAP - SIO ® (SAP Interface Object) – Remedy - Jarad® (JAva Remedy ADapter) – DB - Data Handler ® (DB Adapter)– Filenet– Tuxedo– Alfresco– HL7– jBPM– Italian PS – OpenSPCoop

Connectors

Connectivity Layer

Protocol Adapters– Web Services– http - http/s– RMI– JMS– JDBC– TCP/IP– IIOP– E-mail (POP3, SMTP)– File– FTP, SFTP

SIO® (SAP Interface Object)

Features• Based on Java JCA standard• Use of SAP® JCO API• Bi-directional• Web Services: to manage inbound/outbound requests• Support for:

– Remote Function Calls (RFC)– Business Application Programming Interfaces (BAPI)– Intermediate Documents (IDoc)

Data Handler (DB Adapter)

The GreenVulcano DataHandler* component •high performance •highly configurable •extract, edit, insert, delete data and execute stored procedures / functions

…on one or more tables, on one or more Databases

*Enterprise version only

Data Handler (DB Adapter)

Main features• CRUD Operations on multiple records• Data depending sequence of multiple statements• Records extraction in XML format• Stored procedure/stored function invokation• Operations on multiple tables• Operations on multiple databases• Data Retriever Helper SQL/Java Script• Multi-threaded extractions with data aggregation• Optional return to client of statistical data on operation execution• Transactions are managed

Configuration and monitoring
