TreeIBM Z OMEGAMON Monitor for z/OS sent an alert to the Situation Status tree for Storage Shortage Warning on our production LPAR RSB1.

We can see the LPAR is lacking pageable storage frames causing this shortage that threatens the LPAR.

On drill down to see which address spaces are using the real storage frames we find six zCX address spaces have seen started incorrectly on the production RSB1 LPAR.  These address spaces are fixing frames needed and threating the RSB1 other work.   We can now stop these address spaces from this LPAR and start them on the correct LPAR for that workload.

An OMEGAMON Situation alerted us to this issue allowing us to correct it quickly.
