In addition RMF now supports the new SCM space type for the paging subsytem and SCM paging block data. Pageable Large Page and SCM support is only provided when Flash Web Deliverable JBB778H is installed. +-------------------------------------------------------------+ FIXCAT=IBM.Device.Server.zEC12-2827.Exploitation/K keyword E2827/K +-------------------------------------------------------------+ >>>>>> POSTPROCESSOR PAGING ACTIVITY REPORT <<<<<< The Postprocessor Paging Activity report now shows values for both fixed and pageable 1 MB frames of high virtual common memory. The total number of frames and the number of auxiliary storage slots based on DASD are added. Fields are added to complement information on frames and page data set slots for SCM data blocks. If SCM is not available the SCM Paging Block section is not shown. New fields in the Paging Activity report: Frame and Slot Counts Section: SHARED FRAMES - AUX SCM The number of shared pages backed on Storage Class Memory (SCM). SCM PAGING BLOCKS - TOTAL The total number of 4K SCM paging blocks. SCM PAGING BLOCKS - AVAILABLE The number of SCM blocks that do not contain any data and are available to ASM (total-inUse-bad SCM paging blocks). SCM PAGING BLOCKS - BAD The number of SCM blocks that do not contain any data and are unavailable for use. SCM PAGING BLOCKS - IN-USE The number of SCM blocks that are in-use by ASM. Memory Objects and High Virtual Storage Frames Section: 1 MB FRAMES FIXED - TOTAL Total number of 1 MB frames that can be used by fixed memory objects. This value is equal to the size of the Large Frame Area in megabytes. 1 MB FRAMES FIXED - AVAILABLE Number of 1 MB frames in the Large Frame Area that are not in-use. 1 MB FRAMES FIXED - IN-USE Number of 1 MB frames in the Large Frame Area that are in-use by fixed memory objects. 1 MB FRAMES PAGEABLE - TOTAL Total number of 1 MB frames that can be used by pageable and DREF memory objects. 1 MB FRAMES PAGEABLE - AVAILABLE Number of 1 MB frames that are not in-use by pageable and DREF memory objects. 1 MB FRAMES PAGEABLE - IN-USE Number of 1 MB frames that are in-use by pageable and DREF memory objects. HIGH SHARED FRAMES - TOTAL Size of high virtual shared area in units of 4KB pages. HIGH SHARED FRAMES - AUX DASD Number of auxiliary storage slots used for high virtual shared pages that are backed on DASD. HIGH SHARED FRAMES - AUX SCM Number of auxiliary storage slots used for high virtual shared pages that are backed on SCM storage. HIGH COMMON FRAMES - TOTAL Size of high virtual common area in units of 4 KB pages. HIGH COMMON FRAMES - AUX DASD Number of auxiliary storage slots used for high virtual common memory pages that are backed on DASD. HIGH COMMON FRAMES - AUX SCM Number of auxiliary storage slots used for high virtual common memory pages that are backed on SCM storage. 1 MB Memory Objects and 1 MB Frames are not shown for machines without Enhanced DAT Architecture. +--------------------------------------------------------------+ >>>>>> POSTPROCESSOR VIRTUAL STORAGE ACTIVITY REPORT <<<<<< The Postprocessor Virtual Storage Activity report now shows separat counts for the number of fixed and pageable 1 MB frames instead of showing a total count of 1MB frames. New fields in the Virtual Storage Activity report: MEMORY OBJECTS The MIN, MAX, and AVG values for the number of PRIVATE, SHARED, COMMON memory objects allocated with the indicated job as the owner. Fixed memory objects that can be backed in 1 MB frames are also reported if the Enhanced DAT Architecture is supported. FRAMES (1 MB) The MIN, MAX, and AVG values for the number of 1 MB frames that are used by FIXED and PAGEABLE memory objects with the indicated job as the owner (only available with Enhanced DAT Architecture). The PAGEABLE value also includes 1 MB frames that are used by DREF memory objects. +--------------------------------------------------------------+ >>>>>> POSTPROCESSOR PAGE DATA SET ACTIVITY REPORT The Postprocessor Page Data Set Activity report now shows SCM Paging Block information for page data set of type SCM. Changed field descriptions in the Page Data Set Activity report: PAGE SPACE TYPE Page space type, which can be PLPA, COMMON, LOCAL, or SCM (Storage Class Memory). VOLUME SERIAL Volume serial number of the volume on which the data set resides. N/A for page space type SCM. DEV NUM Number of the device on which the data set resides. N/A for page space type SCM. DEVICE TYPE Device type on which the data set resides. N/A for page space type SCM. SLOTS ALLOC The total number of slots each page data set contains. For page space type SCM, the total number of SCM 4K blocks available to ASM is displayed. --- SLOTS USED --- The number of slots that were being used for paging. For page space type SCM, the total number of SCM 4K blocks in-use by ASM is displayed. BAD SLOTS Number of slots that encountered permanent I/O errors. For page space type SCM, the total number of SCM 4K blocks in error is displayed. DATA SET NAME The name of the page data set being monitored. N/A for page space type SCM. +--------------------------------------------------------------+ >>>>>> MONITOR III STORAGE MEMORY OBJECTS REPORT <<<<<< Changes to the Monitor III Storage Memory Objects (STORM) report: Related to Pageable Large Pages support: - Common Fixed Frames have been taken out of the report. - Area Used % is no longer based on frames backed in central storage but on all frames in LFAREA. - 1 MB Total Frames and % Used of Total frames were replaced by 1 MB Fixed and 1 MB Pageable values. - 1 MB Common Memory Objects and 1 MB Fixed Frames have been added to the system summary section, because the portion of common storage is not related to the address space requesting it. - The number of fixed 1MB frames used to satisfy 1 MB pageable page requests were added. Related to SCM support: - SCM data blocks are included in high virtual common memory auxiliary storage slots (not in report). - High virtual shared memory auxiliary storage slots value has been added for completeness (not in report); SCM data blocks are included. New and changed System Summary fields: Frames %Used Percentage of high virtual common storage used by the system. 1MB MemObj Common Average number of fixed memory objects that are allocated in high virtual common storage and can be backed in 1 MB frames. This value includes the memory objects that cannot be attributed to an address space. 1MB Fixed Total Total number of 1 MB frames that can be used by fixed memory objects. This value is equal to the size of the Large Frame Area in megabytes. Common Average number of 1 MB high virtual common memory pages fixed in central storage. This value includes the pages that cannot be attributed to an address space or have not been freed during address space termination. %Used Percentage of 1 MB frames that are used by fixed memory objects in the Large Frame Area regardless of whether the frames are actually used for 1 MB pages or used to satisfy 4K page requests on a constraint system. 1MB Pgable Initial Number of 1 MB frames that can be used by pageable and DREF memory objects. This value is calculated by the system at IPL time. Dynamic Average number of 1 MB frames in the LFAREA that were used to satisfy 1 MB pageable page requests. %Used Percentage of 1 MB frames that are used by pageable and DREF memory objects, regardless of whether the frames are actually used for 1 MB pages or used to satisfy 4K space requests on a constrained system. New and changed Address Space related fields: 1MB Frames Fixed Average number of 1 MB frames in the Large Frame Area owned by this address space. Frames that are to satisfy 4K space requests on a constrained system are not included. Pgable Average number of 1 MB frames that are used by pageable and DREF memory objects owned by this address space. Pageable memory objects that have been fixed after allocation, are also included. Frames that are either used by common 1 MB pages or to satisfy 4K space requests on a constrained system are not included. These fields are only available with Enhanced DAT Architecture. +--------------------------------------------------------------+ >>>>>> SMF RECORD TYPES 70 TO 79 RMF PRODUCT SECTION <<<<<< The SMF
