PK66153: ABENDU3569 GETMAIN ERROR OUT OF FABBME3 EVEN WHEN RUNNING WITH REGION=0M

APAR status

• Closed as program error.

Error description

• U3569 and MSGFABB3659E received during getmain from FABBME3.
  Error message is as follows:
  FABB3659E - INSUFF. STORAGE FOR: $SPIOVF  - INCREASE REGION SIZE
  
  It's concluded that the Tuning Aid is getting storage from below
  the 16M line when in turn it needs to get the storage from above
  the line (as AMODE=31 vs AMODE=24) to accept larger sized DEDB
  areas.
  
  This is a forward fit of V2R2 PK66040 APAR.

  Forward Fit APAR of FPB V2R2 PK66040.
  DEDB Tuning Aid (FABBME3) got U3569 ABEND with FABB3659E message
  during getmain. FABB3659E message is as follows:
  FABB3659E - INSUFF. STORAGE FOR: $SPIOVF  - INCREASE REGION SIZE
  Even if REGION=0M is specified in the JCL, this abend occurs.
  

Problem conclusion

• DEDB Tuning Aid (FABBME3) attempted to obtain X'8AE893' bytes
  (9,103,507 bytes) for IOVF CI buffer below 16MB boundary
  due to AMODE 24-bit addressing program.
  Because FABBME3 can't obtain the buffer,it issued FABB3659E
  message and got U3659 ABEND.
  FABBME3 should be modified from AMODE 24 to AMODE 31 to
  obtain the buffer above 16MB boundary.
  
  ME3MAIN0 has been modified to change AMODE of FABBME3 from
  24-bit into 31-bit addressing.
  ME3AREA0 and ME3T1XP0 have been modified to obtain all storages
  above 16MB boundary for larger storages.
  ME3EOAP0 has been modified to change FREEMAIN format from R-type
  into RC-type for DOVF and IOVF buffers.
