Revision History



Description of Changes




Initial Version Approved via Design Review


Implementation requirements will include the technical environment (HW,OS, Middleware), external dependencies, teams/locations performing development and procedures for development (e.g. lifecycle model,CM), and a detailed schedule.

Technical environment

No new environment requirements exist for the the LexEVS 6.0, with the exception of load balancing servers.

Software (Technology Stack)

Operating System

  • Linux (though no operating system dependencies currently exist)

Application Server

  • JBoss 4.0.5

Database Server

  • MySQL 5.0.45

Other Software Components

  • caGrid 1.3 / Globus 4.0.3

Server Hardware


  • NCI standard hardware.

Minimum Processor Speed

  • Minimum required by JBoss.

Minimum Memory

  • Minimum required by JBoss.


Expected file server disk storage (in MB)

  • 200GB

Expected database storage (in MB)

  • 100GB


Application specific port assignments

  • Standard port required by JBoss to externalize LexEVS grid service. May be assigned any suitably available port #.

JBoss Container Considerations

There are specific requirements for JBoss containers for LexEVS 5.1.

In order to support multiple versions of LexEVS (for example 5.1 and 6.0), there are JBoss considerations.

  • Grid services can NOT be in the same JBoss container because of naming - they both need to be named /wsrf in the container. This results in the use of 1 JBoss container for LexEVS 5.1 and 1 JBoss container for LexEVS 6.0.

External dependencies
