The linkage information for the address space requesting service from the Server is provided with the MVS name/token service (before an address space can call a routine in another address space it must first link to the servicing address space). No explicit requests for common storage-neither above nor below the line-are made for this purpose by the Server. Instead, a name/token for the calling address space is created with the following specifications:
|
Type |
System owned |
|
Key |
$APC0900 appended with eight binary zeros |
|
Duration |
Non persistent, is deleted automatically when the Server ends abnormally |
The token part contains the necessary linkage information to connect to the Server.
