Oracle Tuxedo Application Runtime for CICS and Batch supports IBM mainframe applications rehosted to Oracle Tuxedo. It provides a combination of APIs and services that allows OLTP and Batch mainframe applications to run unchanged, preserving years of investment in their business logic and data. It protects application’s users from change by supporting standard 3270 terminal emulators, and it provides the familiar APIs and functions that developers use in their mainframe applications. The result is ability to quickly and with low risk migrate legacy mainframe applications to open systems running an industry-leading COBOL and C/C++ application server, leading to substantial cost savings and greater flexibility.
The major features of Oracle Tuxedo Application Runtime for CICS and Batch are as following:
a preprocessor to preprocess the source code, translate EXEC CICS statements and CICS keywords into CICS Runtime interfaces
a robust production environment based on Oracle Tuxedo to execute the converted CICS applications
a robust execution engine to execute the equivalent Korn-shell scripts converted from JCL
a Job Enqueueing Service based on Oracle Tuxedo to emulate Mainframe JES2
