8.16.1 Object information for the VLM

Virtual libraries are emulated and mapped to physical libraries in a process pair consisting
of a VLM (Virtual Library Manager) and a PLM (Physical Library Manager).
In XTCC, the VLM and PLM are represented by small boxes in the VLP. The status of the
VLM is indicated by the colors pink (stopped), green (running), green/brown (running with
the trace switched on), and green/red (in HALT mode).
The following information is displayed:
PID:
Mode:

The trace masks are not specified for customer operation. If the mask contains only binary
zeros or is not present then the corresponding trace is inactive.
