Address Space ComStor Owned Detail attributes

This table provides common storage (CSA, ECSA, SQA, ESQA) 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 OMEGAMON for z/OS: Planning and Configuration Guide.

Age The time since the area was allocated. See Age Units. A valid value is a string of up to 6 characters.

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.

A valid value is an integer. Values appear on the workspace as follows:

Area The common storage area. A valid value is an integer. Values appear on the workspace as follows:

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. A valid value is an integer, displayed as a hexadecimal string. The range for this value is from 0 to 65535.

End Address Ending address of the common storage area. A valid value is an integer, displayed as a hexadecimal string.

Fixed Indicates whether the area is from a fixed, non-pageable subpool. A valid value is an integer. Values appear on the workspace as follows:

Job Name Address space name (JOB/STC name, TSO User ID). A job name of *SYSTEM* indicates that the issuer of the request is unknown. A valid value is a string of up to 8 characters.

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.

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. A valid value is an integer, displayed as a hexadecimal string. A value of -2 indicates "Unknown".

Size Size of the common storage area. A valid value is an integer.

Start Address Starting address of the common storage area. A valid value is an integer, displayed as a hexadecimal string.

Storage Key A hardware feature that protects each frame of central storage from unauthorized use by assigning it a unique storage key. A valid value is an integer.

Subpool The 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. A valid value is an integer.
