Our CV's are up 24x7, and at night we need to do a dcmt vary new copy of all program load modules.
IDMS - all supported releases
The DCMT VARY LOADLIB OFF/ON statement will cause the NEW COPY flag to be set for all programs loaded from that loadlib when it is varied back ON.
When a loadlib is varied online, all the PDEs in its chain are flagged for NEW COPY.
