It’s Your Choice –

COBOL Deployment to .NET or JVM

What new in the latest update What is managed code and why should you care Reusable Frameworks Moving to managed code

Agenda

New capabilities for working with Microsoft Visual Studio 2013 and Microsoft .NET 4.5

New platform support for Windows 8.1, Oracle Linux 6.5, Red Hat Linux 6.5 and AIX 7.1

Many enhancements to increase runtime performance JDBC Connection Sharing And more …..

What’s New in 2.2 Update 1

Managed code = .NET or JVM Native code or unmanaged = everything else

Terminology

Virtual execution environment • Portable Intermediate Language• JIT

Garbage collection Object-oriented Extensive frameworks/Class Libraries COBOL code generated directly to byte code

What is managed code? Different perspectives on why deploy to .NET or JVM? Some lessons learned

Moving to managed code

.NET/JVM are fundamentally built on OO principles Procedural semantics still apply Visual COBOL extensions Samples browser

Object Oriented Programming

Data

Good to go in .NET and JVM Be mindful of performance for IO intensive batch operations Significant improvements to file handling operations with Visual

COBOL VC 2.2+

File Handling

COBOL programs can contain embedded SQL

Your choices:1. Database vendor pre-compiler such as Oracle Pro*COBOL

a) COBSQL provides single compile-step integrated with the IDE

2. Micro Focus OpenESQLa) Connect to any ODBC, JDBC, ADO.NET enabled data source

Database access Primer

procedure division.

exec sql connect to Northwind end-exec

if sqlcode not = 0 display "Error during CONNECT : " SQLCODE display mfsqlmessagetext goback end-if

Oracle does not support managed code using Pro*COBOL Use OpenESQL for JDBC and ADO.NET Use Pro*COBOL directives MODE=ANSI and FIPS to determine non-

standard ANSI syntax Some Oracle extensions supported by OpenESQL other extensions

will need to be reworked No PL/SQL support

Managed code is a fantastic way to modernize your application• Get more done using Java and .NET frameworks• Create new user interfaces and services based deployments

Be prepared• New skills – OO, Java, .NET, frameworks• Check for unsupported options such as APIs and database pre-

compilers Speak to Micro Focus before you start or at least, let us know once

you’ve deployed!
