About This Product

Oracle Tuxedo Application Runtime for IMS (Tuxedo ART for IMS) supports migration of IBM IMS applications from mainframe to Oracle Tuxedo. It provides a combination of APIs, tools, and services that allows both online and batch IMS applications to run unchanged, preserving years of investment in IMS business logic and data. It protects application users from change by supporting standard 3270 terminal emulators. It also supports familiar APIs and functions that developers use in their mainframe applications. The result is the ability to quickly and with low risk migrate legacy COBOL and C/C++ mainframe applications to open systems running Oracle Tuxedo. This provides substantial cost savings, elastic scalability, and greater flexibility.

Key Features and Components

The IMS Runtime provides:

Limitations and Known Issues

Please note the following limitations in ART for IMS:

  1. Only one input message from a terminal is allowed in a single transaction.
  2. Cannot switch to a terminal other than the originator.
  3. Only Message formatting option 1 is supported.
  4. Cannot deploy IMS Region in Tuxedo MP cluster using heterogeneous machines.
  5. Does support IMS default system MOD - DFSMO2 which is used when MOD does not specify both in the application program and the MID "nxt" field. ARTIMS displays the output message as plain text in the terminal, users first need to clear the terminal.
  6. Due to byte ordering differences between "big endian" and "little endian" architectures, when using 'Dynamic Attribute Modification' in COBOL programs you cannot specify a decimal integer for attribute bytes. It is s suggested to specify a hexadecimal value one byte at a time in attribute bytes.
