Address Space Virtual Storage attributes
The Address Space Virtual Storage attribute group provides information about the virtual storage allocated to an address space. The attributes report on low, extended, and large storage. Low storage is that below the 16 Megabyte (MB) line. Extended storage is in the range from 16 MB to 2 Gigabytes (GB). Above 2 GB, storage is referred to as large storage, or “above the bar”. For each category, both fixed and virtual storage are reported on.
Address Space Name The name of the job, TSO user, started task, or APPC address space reported on in the row. A valid value is a string of up to 8 characters.
ASID The address space identifier as it is known to z/OS in hexadecimal. A valid value is an integer, displayed as a hexadecimal string.
Extended Fixed(Mb) The amount of fixed storage (in megabytes) between sixteen megabytes and two gigabytes. A valid value is a number to one decimal places accuracy. Values appear on the workspace as follows:
- -2 = Swapped. The address space is physically swapped.
- -1 = Unavailable. An accurate value cannot be determined.
Extended Virtual(Mb) The allocated virtual storage (in megabytes) between sixteen megabytes and two gigabytes. A valid value is a number to one decimal places accuracy. Values appear on the workspace as follows:
- -2 = Swapped. The address space is physically swapped.
- -1 = Unavailable. An accurate value cannot be determined.
Large Fixed(Mb) The amount of fixed storage above the two gigabytes address (or above the bar). A valid value is a number to one decimal places accuracy. Values appear on the workspace as follows:
- -2 = Swapped. The address space is physically swapped.
- -1 = Unavailable. An accurate value cannot be determined.
Large Inuse Percent The percent of storage in use above the bar, relative to the maximum allowed. A valid value is a number to one decimal places accuracy. Values appear on the workspace as follows:
- -2 = Swapped. The address space is physically swapped.
- -1 = Unavailable. An accurate value cannot be determined.
Large Max The maximum amount of storage above the two gigabyte address (above the bar) that could be allocated by the address space. A valid value is a string of up to 8 characters. The following list contains the suffixes and names for values in 64-bit:
- K (kilobyte, 2^10 = 1,024)
- M (megabyte, 2^20 = 1,048,576)
- G (gigabyte, 2^30 = 1,073,741,824)
- T (terabyte, 2^40 = 1,099,511,627,776)
- P (petabyte, 2^50 = 1,125,899,906,842,624)
- E (exabyte, 2^60 = 1,152,921,504,606,846,976)
- 64 bit = 16E = 2^64
Large Virtual(Mb) The amount of allocated virtual storage above the two gigabyte address (above the bar). A valid value is a number to one decimal places accuracy. Values appear on the workspace as follows:
- -2 = Swapped. The address space is physically swapped.
- -1 = Unavailable. An accurate value cannot be determined.
Low Fixed(Mb) The amount of allocated storage below the 16 megabyte line which is fixed. A valid value is a number to one decimal places accuracy. Values appear on the workspace as follows:
- -2 = Swapped. The address space is physically swapped.
- -1 = Unavailable. An accurate value cannot be determined.
Low Virtual(Mb) The amount of allocated virtual storage below the 16 megabyte line. A valid value is a number to one decimal places accuracy. Values appear on the workspace as follows:
- -2 = Swapped. The address space is physically swapped.
- -1 = Unavailable. An accurate value cannot be determined.
Managed System z/OS operating system in your enterprise that an OMEGAMON for z/OS agent is monitoring. A valid value is a string of up to 32 characters.
Management Status The management status of the address space. A valid value is an integer. Values appear on the workspace as follows:
- 0 = Unknown. If the agent cannot determine a value, it defaults to Unknown.
- 1 = 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. Monitored address spaces are associated with a central storage target value of 0. An address space can be swapped out and still be monitored by the Working Set Manager.
- 2 = 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.
- 3 = Isolated. The address space is storage isolated. An address space in this state is exempt from Working Set Manager action.
- 4 = Nonswap. The address space is nonswappable. An address space in this state is beyond Working Set Manager control.
- 5 = OK. The address space is nonswappable. An address space in this state is beyond Working Set Manager control.
Step Name The name of the step currently executing in the address space. A valid value is a string of up to 8 characters.
Swap Status The swap status of the address space. A valid value is an integer. Values appear on the workspace as follows:
- 0 = Unknown. Swap status is unknown.
- 1 = In. The address space is swapped in and occupies central storage.
- 2 = Out. The address space is swapped out and does not occupy central storage.
- 3 = InNSW. The address space is in central storage and is nonswappable.
- 4 = OutLSW. The address space is logically swapped and occupies central storage.
Total Fixed(Mb) The total amount of fixed storage for the address space. A valid value is a number to one decimal places accuracy. Values appear on the workspace as follows:
- -2 = Swapped
- -1 = Unavailable
Total Virtual The total amount of allocated virtual storage for the address space. A valid value is a number to one decimal places accuracy. Values appear on the workspace as follows:
- -2 = Swapped
- -1 = Unavailable
