IBM Mixed Language Application Modernization Pattern V1.0 is a virtual application pattern used to deploy and manage mixed language applications within a cloud environment using either the IBM Workload Deployer, or on the IBM PureApplication System. Using this pattern, in conjunction with the IBM Web Application Pattern V2.0, enables cloud application writers to efficiently create modern cloud-ready mixed language applications using existing application components written in COBOL, C, and Java Enterprise Edition (JEE).
Existing, time-tested enterprise application assets can therefore be used to create modern applications for the cloud. By utilizing readily available Java skills to extend existing applications into JEE, it is possible to deliver new functionality to meet new business needs faster than rewriting the entire application. This pattern provides a quick, easy, and repeatable deployment of middleware and other components associated with composite, mixed language, transactional applications.
IBM Mixed Language Application Modernization Pattern, along with the IBM Web Application Pattern, automatically provisions various application components and connections to persistence resources to meet the quality of service levels specified for the application. This consistent and repeatable cloud-deployed environment significantly reduces the time required to deploy applications into production and, by automating previously manual steps, lowers the risk of errors in the deployment process.
IBM Mixed Language Application Modernization Pattern V1.0 consists of two key parts:
- Language Runtime capability
- Transactional Extensions capability
The Language Runtime capability comes pre-entitled with the IBM PureApplication System W1700 and provides an execution runtime environment based on IBM WebSphere eXtended Transaction Runtime V2.1 for hosting COBOL and C applications.
The Transactional Extensions capability provides additional capability to host COBOL and C-based business transactions utilizing the IBM CICS APIs. This part also supports migration assist tooling to host applications that have Oracle Tuxedo ATMI API. The Transactional Extensions capability is available separately as a purchasable part. If that functionality is required, the appropriate license must be purchased before use.
