The communication protocol you use depends on the platform configuration of WebSphere® Application Server and IMS™. The IMS TM resource adapter can be deployed to WebSphere Application Server for distributed platforms (AIX®, HP_UX, Linux®, Linux for z/OS®, Solaris, or Windows®) and to WebSphere Application Server for z/OS. The IMS TM Resource Adapter, deployed in WebSphere Application Server, can communicate with IMS Connect using either the TCP/IP or Local Option communication protocol. Whereas TCP/IP uses sockets, Local Option provides non-socket access (an MVS™ program call) to IMS Connect from WebSphere Application Server for z/OS.
If you want to use global transaction support for your IMS and WebSphere Application Server, see Two-phase commit prerequisites for more information. The following table describes the relationship between the different platform configurations, communication protocols, and global transaction support:
Platform of WebSphere Application Server with IMS resource adapter | Supported communication protocol | Global transaction (two-phase-commit) support |
---|---|---|
AIX | TCP/IP | Yes |
HP_UX | TCP/IP | Yes |
Linux | TCP/IP | Yes |
Linux for zSeries® and S/390® | TCP/IP | Yes |
Solaris | TCP/IP | Yes |
Windows | TCP/IP | Yes |
z/OS, OS/390® | TCP/IP Local Option |
Yes Yes |
