3 1 LANSA RDML Client

3.1 LANSA RDML Client

Warning. The RDML BIF has been changed to support 256 byte message and command parameters.
Any ILE program binding to the DCXS882X service program must still use 255 byte parameters.

Three Built-In Functions are required for a LANSA RDML client to have complete interaction with the Java Service Manager services.

These Built-In Functions only allow a single connection within the same job.

3.1.1 JSM_OPEN	Open service.
3.1.2 JSM_COMMAND	Send command.
3.1.3 JSM_CLOSE	Close service.

 

The LANSA developer only needs to understand how to use the commands offered by JSM services.

The overall structure of the LANSA RDML functions will be the same.

The function will perform the following operations:

• OPEN connection to the Java Service Manager.

• Issue a COMMAND to LOAD the service.

• Execute COMMANDs supported by the service.

• Issue a COMMAND to UNLOAD the service

• CLOSE connection to the Java Service Manager
