Using COMTI with IMS

Current versions of COMTI do not support transactional semantics (also known as a twophase commit) on the IMS subsystem. However, you can access an IMS/DB database transaction through a CICS subsystem, front-end transaction processing program. That is, if the mainframe environment supports CICS transaction processing against IMS/DB, you can extend Component Services transactional semantics to the IMS/DB database. In this case, COMTI provides the same services as any other transaction processing program running on CICS. If you do not require transactional semantics, and just want to gain access to your data, you can access IMS directly.
