The MODE parameter does not affect parallel utility execution.
The nucleus cannot run in single-user mode (MODE=SINGLE cannot be specified) if it is to run
with Adabas Parallel Services or Adabas Cluster Services (NUCID 1)
with support for distributed transactions (DTP=RM)
as an Adabas Transaction Manager (DTP=TM)
In addition, a valid Adabas SVC should be specified when running in single-user (MODE=SINGLE) mode.
When running several nuclei against the same database, only one update nucleus can be used.
