DFS151 LTERM KEYWORD PARAMETER IS INVALID
Explanation
The logical terminal name specified was not defined to the system.
If this IMS system is part of a sysplex using the IMS Resource Manager, the logical terminal (LTERM) name might be actively on or owned by another IMS system. As a result, the LTERM name would not be found on this IMS, even if it was statically defined to the system.
System action
The command is ignored.
