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.

ASID The address space identifier as it is known to z/OS in hexadecimal.

Address Space Name The name of the job, TSO user, started task, or APPC address space reported on in the row. Valid value is an alphanumeric string, with a maximum of 8 characters.

Extended Fixed The amount of fixed storage (in megabytes) between 16 MB and 2 GB. If an accurate value cannot be determined, the value is displayed as Unavailable. If the address space is physically swapped, Swapped is displayed.

Extended Virtual The allocated virtual storage (in megabytes) between 16 MB and 2 GB. If an accurate value cannot be determined, the value is displayed as Unavailable. If the address space is physically swapped, Swapped is displayed.

Large Fixed The amount of fixed storage above the 2 GB (or above the bar) address range. If an accurate value cannot be determined, the value is displayed as Unavailable. If the address space is physically swapped, Swapped is displayed.

Large Inuse Percent The percent of storage in use above the bar, relative to the maximum allowed. Valid value is a 2-byte integer in the range 0.0 - 100.0. If an accurate value cannot be determined, the value is displayed as Unavailable. If the address space is physically swapped, Swapped is displayed.

Large Max The maximum amount of storage above the bar (2 GB boundary) that could be allocated by the address space. If an accurate value cannot be determined, the value is displayed as Unavailable. If the address space is physically swapped, Swapped is displayed. The following list contains the suffixes and names for values in 64-bit:

Large Virtual The amount of allocated virtual storage above 2 GB (above the bar). If an accurate value cannot be determined, the value is displayed as Unavailable. If the address space is physically swapped, Swapped is displayed.

Low Fixed The storage below the 16 MB line, which is fixed in megabytes. If an accurate value cannot be determined, the value is displayed as Unavailable. If the address space is physically swapped, Swapped is displayed.

Low Virtual The amount of allocated virtual storage for this address space below the 16 MB line, in megabytes. If an accurate value cannot be determined, the value is displayed as Unavailable. If the address space is physically swapped, Swapped is displayed.

Managed System A z/OS operating system in your enterprise that is being monitored by an IBM Z OMEGAMON Monitor for z/OS agent. Valid value is a character string with a maximum length of 32 bytes in the format <plexname>:<smfid>:MVSSYS.

Management Status The management status of the address space. Valid values are:

Step Name The address space step name currently executing. Valid value is an alphanumeric string, with a maximum of 8 characters.

Swap Status The swap status of the address space. Valid values are:

Total Fixed The total amount of fixed storage, in megabytes, for the address space. If an accurate value cannot be determined, the value is displayed as Unavailable. If the address space is physically swapped, Swapped is displayed.

Total Virtual The total amount of allocated virtual storage, in megabytes, for the address space. If an accurate value cannot be determined, the value is displayed as Unavailable. If the address space is physically swapped, Swapped is displayed.
