Address Space ComStor Owned Detail attributes

This attribute group provides common storage (CSA, ECSA, SQA, ESQA) detail information for areas owned by the selected address space.
Note: The CSA Analyzer must be running for data to be available for these attributes. For information on configuring the CSA Analyzer, see the IBM® Z OMEGAMON AI for z/OS Planning and Configuration Guide..

% of Total Percentage of the total common storage area in use by this address space. Valid values in the range 0-100.

Age Time since the area was allocated.

Age Units The units in which the age is reported, either hours, days, or minutes. In the format DDD:HH, HH:MM, or MM:SS.

Area Common storage area. Valid value is one of the following:

  • CSA (common service area)
  • ECSA (extended common service area)
  • SQA (system queue area)
  • ESQA (extended system queue area)

ASID Address space ID in hexadecimal. The address space ID is a unique number assigned to an address space when it is created. It is used by z/OS to differentiate between address spaces.

End Address Ending address of the common storage area. Valid value is a 4-byte hexadecimal number.

Fixed Indicates whether the area is from a fixed, non-pageable subpool (Yes, No).

Job Name Address space name (JOB/STC name, TSO User ID). Valid value is a character string with a maximum length of 8 bytes. A job name of *SYSTEM* indicates that the issuer of the request is unknown.

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

Requestor Return Address The return address of the GETMAIN request, which is the next instruction following the GETMAIN. If the return address cannot be determined (the storage was obtained before the VSM service was active), the address is given as Unknown. Valid value is a 4-byte hexadecimal number.

Size Size of the common storage area. Valid value is a 4-byte integer.

Start Address Starting address of the common storage area. Valid value is a 4-byte hexadecimal number.

Storage Key Unique key assigned to the frame to protect it from unauthorized use.

Subpool Subpool of the common storage space area. For CSA, valid values are subpools 227, 228, 231, and 241. For SQA, valid values are subpools 226, 239, and 245. Although related by common area, these subpools have different characteristics. CSA subpools 227 and 228, for example, are fixed in storage, while subpools 231 and 241 are pageable.
