Real storage utilization history attributes
The historical real storage utilization attribute group provides information about the real storage allocated to an address space in terms of various types of frame counts and slot counts, as well as the management status of a given address space.
1 Meg Frames In Real (RMF metric) The number of 1 Megabyte frames backed in real storage.
Active Frames (RMF metric) The number of active frames occupied by the address space.
ACTIVE = SUM Central Srorage Frames / # Samples
Active Frames DIV (RMF metric) The number of active Data-in-Virtual frames actively used by the address space.
DIV = SUM DIV Frames / # DIV Samples
Active Frames Fixed (RMF metric) The number of fixed frames actively used by the address space.
FIXED = SUM Fixed Frames / # Samples
Active Frames Working Set (RMF metric) The number of active frames contained in the working set.
The working set value represents the average amount of storage (in frames) a user occupied while in central and expanded storage (not swapped), including dataspaces and hiperspaces. Shared page counts are not included in working set.
ASID The address space ID of the job (hexadecimal format). The address space id of a Job, TSO Userid, started task or UNIX System Services address space.
Auxiliary Storage Slots (RMF metric) The number of auxiliary storage slots occupied by this address space. Valid value is a 4-byte integer.
Dedicated Memory Eligible Indicates if an address space is using dedicated memory. The format is an integer that can have one of the following values: Unavailable=0xFF, No=0x01, Yes=0x02, or Unknown=0x03.
DMEM 4K Available Average amount of dedicated memory assigned to the address space in 4K frames currently not in use. The valid value is a long integer. A value of -1 indicates Unavailable.
DMEM 1M Available Average amount of dedicated memory assigned to the address space in 1MB frames currently not in use. The valid value is a long integer. A value of -1 indicates Unavailable.
DMEM 2G Available Average amount of dedicated memory assigned to the address space in 2G frames currently not in use. The valid value is a long integer. A value of -1 indicates Unavailable.
DMEM 4K In Use Average amount of dedicated memory assigned to the address space in 4K frames currently in use. The valid value is a long integer. A value of -1 indicates Unavailable.
DMEM 1M In Use Pageable Average amount of dedicated memory assigned to the address space in 1M pageable frames currently in use. The valid value is a long integer. A value of -1 indicates Unavailable.
DMEM 1M In Use Fixed Average amount of dedicated memory assigned to the address space in 1M fixed frames currently in use. The valid value is a long integer. A value of -1 indicates Unavailable.
DMEM 2G In Use Average amount of dedicated memory assigned to the address space in 2G frames currently in use. The valid value is a long integer. A value of -1 indicates Unavailable.
DMEM 2G Minimum Requested Minimum amount of dedicated memory requested by the address space in 2G units. The valid value is a long integer. A value of -1 indicates Unavailable.
DMEM 2G Requested Average amount of dedicated memory requested by the address space in 2G units. The valid value is a long integer. A value of -1 indicates Unavailable.
DMEM 2G Assigned Average amount of dedicated memory assigned to the address space in 2G units. The valid value is a long integer. A value of -1 indicates Unavailable.
Fixed 2GB Pages In Central Storage Number of 2GB pages fixed in real storage owned by this address space.
Freemained Frames Number of freemained frames owned by this address space.
Idle Frames (RMF metric) The number of idle frames occupied by the address space.
IDLE = SUM Central Storage Idle Frames / # Samples
Job Name (RMF metric) The name of the Job, the TSO Userid, the name of the started task or the name of an UNIX System Services address space. Valid value is a string, with a maximum of eight characters.
Managed System A z/OS operating system in your enterprise that is being monitored by an IBM® Z OMEGAMON® AI for z/OS® agent. Valid value is a character string with a maximum length of 32 bytes.
Memory Objects 2GB Fixed Number of 2GB memory objects owned by this address space.
Memory Objects Allocated The number of memory objects allocated by this address space. Valid value is a 4-byte integer.
Page-In Rate (RMF metric) Page-In rate (Page-ins per second).
PAGE IN RATE = SUM Page-in Counts for Group / Resident Time
The calculation is the total number of non-swap page-ins (including VIO page-ins, hiperspace page-ins, shared page group page-ins, and page-ins caused by page faults) during the range period divided by the total time an address space was swapped-in (resident time) in seconds.
Recording End Time Time at the end of the RMF reporting interval for the current row of near-term historical data. The valid format is yy/mm/dd hh:mm:ss.
Recording Start Time Time at the start of the RMF reporting interval for the current row of near-term historical data. The valid format is yy/mm/dd hh:mm:ss.
RMF Status Status indications for availability of RMF and lock data.
Sample Period Sample period in seconds.
Service Class The service class name. Valid value is a string, with a maximum of eight characters. This field displays unavailable if the system is in compatibility mode. If a job changes its service class during the report interval, RMF displays eight asterisks (********) instead of the service class name. If the service class is not available, RMF displays eight dashes (--------).
Shared Page-In Rate (RMF metric) Shared page-in rate from auxiliary storage (Page-ins per second).
Shared storage page-in rate from auxiliary storage. The page-in rate is calculated by dividing the total number of shared pages brought in from auxiliary storage by the resident time. (The resident time is the total time an address space was swapped-in in seconds).
Shared Pages Total Views (RMF metric) The total shared page views. Valid value is a 4-byte integer.
Shared Pages Total Valid (RMF metric) The total valid shared pages. Valid means that the page is brought into central storage and is made addressable for the address space.
Shared Pages Validation Rate (RMF metric) The shared page validation rate of the address space.
Total Frames (RMF metric) The total number of frames occupied by the address space. The sum of the ACTIVE and IDLE frames. The shared page counts are not included in TOTAL.
SMF IDSMF ID as defined in the IEASYM or IEASYS PARMLIB members.
