The choice of connection module to be linked to an application program depends on whether the application program is to interact with the independent DBH or the linked-in DBH.
There is one connection module only per operating mode for application programs that interact with the independent DBH:
TIAM applications are linked with the connection module SESMOD,
DCAM applications are linked with SESDCAM, and UTM applications are linked with SESUTMC.
Application programs that interact with the linked-in DBH always have to be linked with the SESLINK connection module. SESLINK is already linked with the SEDI61L and SEDI63L utilities.
Connection module | DBH | Operating mode | Category |
SESMOD | independent DBH | TIAM | DBCON |
SESDCAM | independent DBH | DCAM (CALL-DML only) | |
SESUTMC | independent DBH | UTM | |
SESLINK | linked-in DBH | DBCONL |
