The Address Space Real Storage 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.
Address Space Name The name of the job, TSO user, started task, or APPC address space reported on in the row. Valid value is a simple text string of from 1 to 8 characters.
Central Frame Count The total number of central storage frames, including any frames that are backing user dataspaces. Valid value is a 4-byte integer.
Expanded Frame Count The total number of expanded storage frames, including any dataspace frames that have been paged out to expanded storage.
Fixed Frame Count The total number of fixed frames, including fixed frames found on the pageable frame queue and all frames found on the fixed frame queue. Valid value is a 4-byte integer.
Hiperspace Frame Count The total number of hiperspace frames. Hiperspace allows a program to store and retrieve data directly from expanded storage, thus avoiding the overhead of DASD I/O. Valid value is a 4-byte integer.
Managed System A z/OS operating system in your enterprise that is being monitored by a Tivoli OMEGAMON XE on z/OS agent. Valid value is a character string with a maximum length of 32 bytes.
Management Status The management status of the address space. Valid values are:
Monitored--The Working Set Manager has noticed that the address space is using an excessive amount of CPU for paging and is actively keeping track of its central storage use and paging rates.
Managed--The Working Set Manager has determined that the paging rate of the monitored address space continues to be excessive and some type of action must be taken.
Isolated--The address space is storage isolated. An address space in this state is exempt from Working Set Manager action.
NonSwap--The address space is non-swappable and is therefore beyond Working Set Manager control.
OK--The address space is of no interest to the Working Set Manager.
Unknown--The management status of the address space is unknown.
Non-virtual I/O Slot Count The number of 4K blocks allocated in auxiliary storage for pages other than virtual I/O pages. Valid value is a 4-byte integer.
Swap Status The swap status of the address space. Valid values are:
IN--The address space is swapped in and occupies central storage
OUT--The address space is swapped out and does not occupy central storage.
IN NSW--The address space is in central storage and is non-swappable.
OUT LSW--The address space is logically swapped and occupies central storage.
UNKNOWN--Swap status is unknown.
User Key Dataspace The maximum number of 4K virtual storage blocks of user key dataspace that can be used by this address space. Valid value is a 4-byte integer.
Virtual I/O Slot Count The number of 4K blocks allocated in auxiliary storage for virtual I/O pages. Valid value is a 4-byte integer.
