If your UTM application is running with the common runtime system environment CRTE (Common RunTime Environment), it is possible to load the shareable parts of CRTE via DSSM. Other runtime systems also offer this option.
The BS2000 system administrator is responsible for loading the subsystem; for further information see the CRTE manual.
As far as possible, you should use this procedure because it saves system resources. In particular, the runtime system for C and COBOL, which are contained in CRTE, must be loaded as a CRTE subsystem because they are also required by KDCROOT.
If the CRTE runtime system is preloaded, you can use this by using the SYSLNK.CRTE.PARTIAL-BIND library during linkage. The connection to the CRTE subsystem is then established by a connection module incorporated when linking the start LLM. If the CRTE runtime system cannot be accessed, the connection module dynamically loads the necessary parts from the CRTE library into the local task area.
