The advantages of sharing dual-purpose definitions are:
- You can use this method whether or not your systems share a CSD file,
so you can use it for transaction routing between different MVS images.
- Disk storage use is reduced because you need only one CSD file record.
- Maintenance is reduced because you need only one CSD file record.
- Virtual storage use is reduced because you install the definition in only
one system.
- You can autoinstall the terminal in the terminal-owning system, and in effect autoinstall it in the application-owning systems.
(Shipping terminal definitions has the same effect as autoinstall, but does
not itself involve the autoinstall process.)
