Collection Services data files: QAPMSHRMP
This database file reports shared memory pool data.
Data is generated only when a partition is defined to use a shared memory pool. Data is reported for both the partition's use of the pool as well as pool metrics that are the sum of activity caused by all partitions using the pool.
A POWER6® system with firmware level xx340_075 is the minimum hardware requirement for this data to be available.
A POWER7® system
is the minimum hardware requirement for the deduplication data to
be available.
| Field Name | Description | Attribute |
|---|---|---|
| INTNUM | Interval number: The nth sample database interval based on the start time specified in the Create Performance Data (CRTPFRDTA) command. | PD (5,0) |
| DATETIME | Interval date and time. The date and time of the sample interval. | Timestamp |
| INTSEC | Elapsed interval seconds. The number of seconds since the last sample interval. | PD (7, 0) |
| SMPOOLID | Shared memory pool identifier. The identifier of the shared memory pool which this partition is using. | B (5,0) |
| SMWEIGHT | Memory weight. Indicates the variable memory capacity weight assigned to the partition. Valid values are hex 0 -255. The larger the value, the less likely this partition is to lose memory. | B (3,0) |
| SMREALUSE | Physical real memory used. The amount of shared physical real memory, in bytes, that was being used by partition memory at sample time. | B (18, 0) |
| SMACCDLY | Real memory access delays. The number of partition processor waits that have occurred because of page faults on logical real memory. | B (18, 0) |
| SMACCWAIT | Real memory access wait time. The amount of time, in milliseconds, that partition processors have waited for real memory page faults to be satisfied. | B (18, 0) |
| SMOVRCAP | Reserved | B (18, 0) |
| SMENTIOC | Entitled memory capacity for I/O. The amount of memory, in bytes, currently assigned to the partition for use by I/O requests. | B (18, 0) |
| SMMINIOC | Minimum entitled memory capacity for I/O. The minimum amount of entitled memory, in bytes, needed to function with the current I/O configuration. | B (18, 0) |
| SMOPTIOC | Optimal entitled memory capacity for I/O. The amount of entitled memory, in bytes, that would allow the current I/O configuration to function without any I/O memory mapping delays. | B (18, 0) |
| SMIOCUSE | Current I/O memory capacity in use. The amount of I/O memory, in bytes, currently mapped by I/O requests. | B (18, 0) |
| SMIOCMAX | Maximum I/O memory capacity used. The maximum amount of I/O memory, in bytes, that has been mapped by I/O requests since the partition was last IPLed or the value was reset by an explicit request. | B (18, 0) |
| SMIOMDLY | I/O memory mapping delays. The cumulative number of delays that have occurred because insufficient entitled memory was available to map an I/O request since the partition was last IPLed. | B (18, 0) |
| MPACCDLY | Pool real memory access delays. The number of virtual partition memory page faults within the shared memory pool for all partitions. | B (18, 0) |
| MPACCWAIT | Pool real memory access wait time. The amount of time, in milliseconds, that all partitions processors have spent waiting for page faults to be satisfied within the shared memory pool. | B (18, 0) |
| MPPHYMEM | Pool physical memory. The total amount of physical memory, in bytes, assigned to the shared memory pool | B (18, 0) |
| MPLOGMEM | Pool logical memory. The summation, in bytes, of the logical real memory of all active partition active partitions served by the shared memory pool. | B (18, 0) |
| MPENTIOC | Pool entitled I/O memory. The summation, in bytes, of the I/O entitlement of all active partitions served by the shared memory pool. | B (18,0) |
| MPIOCUSE | Pool entitled I/O memory in use. The summation, in bytes, of I/O memory mapped by I/O requests from all active partitions served by the shared memory pool. | B (18,0) |
| SMFIELD1 | Partition logical memory
deduplicated. The amount of the partition’s logical memory (in bytes)
mapped to a smaller set of physical pages in the shared memory pool
because it was identical to other pages in the shared memory pool. |
B (18,0) |
| SMFIELD2 | Reserved | B (18,0) |
| SMFIELD3 | Reserved | B (18, 0) |
| SMFIELD4 | Pool physical memory deduplicated.
The amount of physical memory (in bytes) within the shared memory
pool that logical pages of memory from the partitions sharing the
pool have been mapped to because of deduplication. |
B (18, 0) |
| MPFIELD1 | Unscaled deduplication time.
The amount of processing time, in microseconds, spent deduplicating
logical partition memory within the shared memory pool. |
B (18, 0) |
| MPFIELD2 | Scaled deduplication time.
The amount of scaled processing time, in microseconds, spent deduplicating
logical partition memory within the shared memory pool. |
