Don't overlook the type 74 subtype 4 Structure data where the SCM statistics per Structure are reported.
TYPE74ST in MXG 33.07 has all of these new R744Mxxxx variables: /* TYPE 74 SUBTYPE 4 MO SECTION*/ R744MAEC='SCM*AUXILIARY*ENABLED*COMMANDS' R744MALG='SCM*ALGORITHM*TYPE' R744MEMA='EST MAX*ASSIGNED*AUGMENTM SPACE' R744MEME='EST MAX*LIST*ELEMENTS*IN SCM' R744MEML='EST MAX*LIST*ENTRIES*IN SCM' R744MENE='EXISTING*LIST*ELEMENTS*IN SCM' R744MENL='EXISTING*LIST*ENTRIES*IN SCM' R744MFAU='FIXED*AUGMENTED*SPACE' R744MIUA='AUGMENTED*SPACE*IN USE*BY THIS STRUCTURE' R744MIUS='SCM*IN USE*BY THIS*STRUCTURE' R744MMBE='MAX*LIST ELEMENTS*PER SCM*BUFFER' R744MNEL='MIN*LIST ELEMENTS*MUST BE*AVAILABLE' R744MNEC='MIN*LIST ENTRIES*MUST BE*AVAILABLE' R744NSRK='REFERENCES*FOR MIGRATING*KEY-RANGE' R744MMBL='MAX*LIST ENTRIES*PER SCM*BUFFER' R744MRBT='SCM*READ*BYTES*TRANSFERRED' R744MRFC='SCM*READ OPS*LIST*REFERENCE' R744MRPC='SCM*READ OPS*PREFETCH OP' R744MRSQ='SQUARES OF*R744MRST' R744MRST='SCM*READ OPS*SERVICE*TIME' R744MSLR='PCT*LIST COUNTS*LOWER*REGULATOR' R744MSLT='PCT*LIST COUNTS*LOWER*THRESHOLD' R744MSMA='MAX*SCM*STRUCTURE*CAN USE' R744MSRL='SCM*REFERENCES*LIST*STRUCTURE' R744MSRM='SCM*REFERENCES*MIGRATION' R744MSRR='SCM*REFERENCES*LIST*HASHING' R744MSUR='PCT*LIST COUNTS*UPPER*REGULATOR' R744MSUT='PCT*LIST COUNTS*UPPER*THRESHOLD' R744MSWC='SCM LIST WRITES' R744MWBT='SCM*WRITE*BYTES*TRANSFERRED' R744MWSQ='SQUARES OF*R744MWST' R744MWST='SCM*WRITE OPS*SERVICE*TIME' Barry Herbert W.

Are we trying to capture dumps into an already overly-full memory / SCM situation? This thread (and a SEPARATE customer situation) prompted a discussion today in my team about doing more with the SMF 75 (and 71) data now that SCM is quite commonplace.

MAXSPACE has nothing to do with it. You would get a different reason code for MAXSPACE. Jim Mulder z/OS System Test IBM Corp.
