This section describes the interface between generation and the sign-on procedure for clients if the application is generated with user IDs. The sign-on procedure is made up of the following two stages: establishing the connection and signing on.
The connection is established using the application names as specified in the operand BCAMAPPL= or, for OpenCPIC, specified in the operand LOCAL-ACCESS-POINT=.
Signing on to a UTM application
Signing on to a UTM application is carried out using a user ID. The following stages are required, regardless of whether the default sign-on service is used or another sign-on service:
When using terminals, the terminal user must prove their authorization once a connection has been established. To do this the user must enter at least one user ID. This user ID must be generated in a USER statement. This is also called the real user ID.
TS applications, UPIC clients and HTTP clients are signed on after connection using a so-called connection user ID. This is a user ID which is
either a user ID implicitly generated by openUTM using the LTERM name if no user ID is specified in the operand USER= of the LTERM statement,
or an explicit connection user ID, if a user ID is specified in the operand USER= which is generated with a USER statement, see "Automatic sign-on under a specific user ID". This user ID cannot be used as a real user ID.
OpenCPIC clients are signed on under their association names once the association has been established. The association names are formed using the names specified in the operand ASSOCIATION-NAMES= and a sequential number, for example, ASSOC03, see "OSI-LPAP - define an OSI-LPAP partner for distributed processing based on OSI TP"
UPIC clients, HTTP clients, TS applications and OpenCPIC clients which are signed on using a connection user ID or using their association name can then subsequently sign on using a real user ID.
The execution of the sign-on service can be defined by the generation, for example, using automatic connection establishment, automatic sign-on under a specific user ID, separate sign-on service or by permitting multiple sign-ons.
- Detailed information about the sign-on service can be found in the relevant section of the openUTM manual “Using UTM Applications”. The individual steps required for a client to sign on to a UTM application are described there.
