Question:

If a customer has multiple LPARs (SYSA and SYSB).  On SYSA they have the Gen Host Encyclopedia installed.  On the SYSB(CPU2) they only the GEN runtime libs (only Load Library), nothing else.  Do they need LMP KEYS on SYSB(CPU2)?

Answer:

Gen does LMP Key checking for TCP/IP DC and MQ.  Gen only puts out warnings, but do not stop the application(s) from executing. Gen does not perform LMP checks for regular Runtimes (such as Block Mode or Batch applications).
