DFHSTOR user storage fields

DFHSTOR owns the following performance class data fields relating to user storage. For additional information on the user storage fields, see User storage.

033 (Type-A, SCUSRHWM, 4 bytes)
Maximum amount (high-water mark) of user-storage allocated to the user task below the 16MB line, in the user dynamic storage area (UDSA).
054 (Type-A, SCUGETCT, 4 bytes)
The number of user-storage GETMAIN requests issued by the user task for storage below the 16MB line, in the UDSA.
095 (Type-A, SCUSRSTG, 8 bytes)
The storage occupancy of the user task below the 16MB line, in the UDSA. This is a measure of the area under the curve of the storage in use against elapsed time. For more information, see User storage occupancy.
105 (Type-A, SCUGETCT, 4 bytes)
The number of user-storage GETMAIN requests issued by the user task for storage above the 16MB line, in the EUDSA.
106 (Type-A, SCUSRHWM, 4 bytes)
Maximum amount (high-water mark) of user-storage allocated to the user task above the 16MB line, in the user dynamic storage area (EUDSA).
107 (Type-A, SCUSRSTG, 8 bytes)
The storage occupancy of the user task above the 16MB line, in the EUDSA. This is a measure of the area under the curve of the storage in use against elapsed time. For more information, see User storage occupancy.
116 (Type-A, SC24CHWM, 4 bytes)
Maximum amount (high-water mark) of user-storage allocated to the user task below the 16MB line, in the CICS® dynamic storage area (CDSA).
117 (Type-A, SCCGETCT, 4 bytes)
The number of user-storage GETMAIN requests issued by the user task for storage below the 16MB line, in the CDSA.
118 (Type-A, SC24COCC, 8 bytes)
The storage occupancy of the user task below the 16MB line, in the CDSA. This is a measure of the area under the curve of the storage in use against elapsed time. For more information, see User storage occupancy.
119 (Type-A, SC31CHWM, 4 bytes)
Maximum amount (high-water mark) of user-storage allocated to the user task above the 16MB line, in the CICS dynamic storage area (CDSA).
120 (Type-A, SCCGETCT, 4 bytes)
The number of user-storage GETMAIN requests issued by the user task for storage above the 16MB line, in the ECDSA.
121 (Type-A, SC31COCC, 8 bytes)
The storage occupancy of the user task above the 16MB line, in the ECDSA. This is a measure of the area under the curve of the storage in use against elapsed time. For more information, see User storage occupancy.
