Migration Guide : Migrating from Version 4.0, 4.01, or 4.02 : Other migration concerns : MVS applications that reference subsystem type 'TM'
MVS applications that reference subsystem type 'TM'
In Versions 4.0, 4.01, and 4.02, the XD image types included--
CICS MVS Target
CICS OS/2 Target
CICS Windows NT Target
Native MVS
Native MVS (OS/2 Target)
Native MVS (Windows NT Target)
IMS MVS Target
In Version 4.5, the image types changed to the following:
MVS
MVS Simulation (OS/2 Target)
MVS Simulation (Windows NT Target)
OS/2
Windows NT
AIX
The image types now apply to the platform they represent. The CICS and IMS API's must be loaded into the image type as a feature. If your application checks the value of the subsystem type "TM" when loaded into an image, do either of the following before loading your application into a Version 6.0 image: load the CICS or IMS feature or change your application so it checks for a different subsystem type at runtime.
