Autoinstall programs started by EXEC CICS LINK commands

Autoinstall programs have a relationship to the dynamic routing program. When the autoinstall control program is started because there is no installed definition of a program named on an EXEC CICS LINK command without a SYSID, the autoinstall control program can install a different definition depending on the circumstances.

The autoinstall control program can install the following definitions:

A local definition of the server program: CICS® runs the server program on the local region.
A definition that specifies REMOTESYSTEM(remote_region) and DYNAMIC(NO): CICS ships the LINK request to the remote region.
A definition that specifies DYNAMIC(YES): CICS starts the dynamic routing program to route the LINK request.
Note: The DYNAMIC attribute takes precedence over the REMOTESYSTEM attribute. Therefore, a definition that specifies both REMOTESYSTEM(remote_region) and DYNAMIC(YES) defines the program as dynamic, instead of located on a particular remote region. In this case, the REMOTESYSTEM attribute names the default server region passed to the dynamic routing program.
No definition of the server program: CICS starts the dynamic routing program to route the LINK request.
Note: This situation assumes that the autoinstall control program does not install a definition. If no definition is installed because autoinstall fails, the dynamic routing program is not started.
