1 Oracle Tuxedo Mainframe Adapter for SNA Overview
Oracle Tuxedo Mainframe Adapter for SNA allows Application-to-Transaction Monitor Interface (ATMI) applications to communicate with the mainframe. The Oracle Tuxedo Mainframe Adapter products provides domain-compliant gateways that permit administration of the remote Transaction Processing (TP) system as a foreign domain.
The Tuxedo Mainframe Adapter domain architecture extends the scope of ATMI platforms to provide coordinated transaction processing across an enterprise's geographic or organizational boundaries. Within each domain, the administrator determines which local services are available to other specific domains, thus enabling client applications to request those services.
The domain gateway architecture is designed for the ATMI application administrator, who makes services in other domains available to application programmers. The existence of applications within distinct domains is, however, totally transparent to the application programmers. They can use ATMI programming paradigms to request services offered in other domains as if they were services offered within the local application.
The ATMI application administrator enables remote domains to access a subset of Local Services. This subset is called a Local Domain. The local domain helps the administrator provide secure “views” of the application.
The Oracle Tuxedo Mainframe Adapter for SNA Gateway communicates between independent Logical Units (LUs) using LU6.2 sessions and conversations. It adds multi‑domain connectivity, bidirectional request/response, and conversations between ATMI platforms and System Network Architecture (SNA)-based applications. It provides support for DPL and DTP transactions in a CICSplex environment. It provides access to Application Program-to-Program Communication (APPC) applications based on SNA as well as inter-system communication with Customer Information Control System/Enterprise System Architecture (CICS/ESA). When accessing CICS/ESA systems, the Oracle Tuxedo Mainframe Adapter for SNA acts as a CICS/ESA region, capable of supporting the following sync-level 2 functions:
- Bidirectional request/response and conversational service requests
- Peer support for CICS/ESA and support for multiple remote MVS regions
- Event monitoring and reporting
- Both static and dynamic configuration support where allowed by SNA
- Automatic data conversion between UNIX and host formats
- Security through Access Control Lists on the local domain
- User and password security for CICS/ESA and IMS communications
- Security access through plug-in for third-party security software
