Function: This report allows the user to summarize the usage
of various DFSMS classes by various departments
and users.
The report shows the user which departments are
using a particular class and helps to detect
potential violations, and to make sure DFSMS is
assigning classes correctly.
DFSMS classes are set either by the user or by the
DFSMS ACS routines, and are used to group data
sets with similar attributes and needs.
Features: The user specifies the class to be summarized:
storage group, data class, storage class, or
management class. The report shows the names of
the various users of each class, the number of
data sets using the class, and the amount of space
this represents, both in terms of space allocated
and space used.
Users can report class usage based on one or more
of the account fields, one or more data set name
nodes, or by using a user-defined table that
translates the data set name prefix into an owner
description.
The ability to include data from real DASD plus
HSM allows the ability to monitor SMS classes as
data sets migrate through various storage levels.
SMS This report is useful during SMS implementation to
Issues: ensure that your SMS ACS routines are assigning
class names as designed. After SMS
implementation, the report is useful for
monitoring the usage of SMS classes by various
departments/users.
COLUMN DESCRIPTIONS
Storage Class
The name of the DFSMS Storage Class for which this
summarization applies. A value of '(NONE)' is
used to represent data sets that have not been
assigned to any class. The report options screen
is used to select which of the four DFSMS
constructs (Storage Class, Management Class, Data
Class, or Storage Group) will appear on this
summary report.
Management Class
The name of the DFSMS Management Class for which
this summarization applies. A value of '(NONE)'
is used to represent data sets that have not been
assigned to any class. The report options screen
is used to select which of the four DFSMS
constructs (Storage Class, Management Class, Data
Class, or Storage Group) will appear on this
summary report.
Data Class
The name of the DFSMS Data Class for which this
summarization applies. A value of '(NONE)' is
used to represent data sets that have not been
assigned to any class. The report options screen
is used to select which of the four DFSMS
constructs (Storage Class, Management Class, Data
Class, or Storage Group) will appear on this
summary report.
Storage Group
The name of the DFSMS Storage Group for which this
summarization applies. A value of '(NONE)' is
used to represent data sets that have not been
assigned to any group. The report options screen
is used to select which of the four DFSMS
constructs (Storage Class, Management Class, Data
Class, or Storage Group) will appear on this
summary report. Because Storage Group is not
available for data sets managed by HSM, values of
'HSM LV1' (migration level 1), 'HSM LV2'
(migration level 2) and 'HSM BACK' (HSM backup)
will appear in this column for HSM data.
Data Owner
The value used as the summarization key for this
report. Depending on the values specified on the
report option screen, this will represent one or
more VCA account elements, one or more nodes of
the data set name, or will contain a value derived
from your Data Set Group table.
Total Data Sets
The total number of data sets found in the input
data that were assigned to this class or group.
Non-VSAM Data Sets
The total number of data sets found in the input
data that were assigned to this class or group and
were defined as having a data set organization
other than VSAM. This value includes only data
sets that still reside on primary DASD (no HSM
data).
VSAM Data Sets
The total number of data sets found in the input
data that were assigned to this class or group and
were defined as having a VSAM organization. This
value includes only data sets that still reside on
primary DASD (no HSM data).
HMIG Data Sets
The total number of data sets found in the input
data that were assigned to this class or group and
had been migrated to HSM level 1 or level 2
volumes.
HBAC Data Sets
The total number of data sets found in the input
data that were assigned to this class or group and
belonged to data sets residing on the HSM backup
volumes. Each unique data set is only included
once in this count, even if multiple backup copies
exist.
Total Megabytes Allocated
The total amount of allocated space found in the
input data that was assigned to this class or
group, expressed in millions of bytes (megabytes).
Non-VSAM Megabytes Allocated
The total amount of allocated space found in the
input data that was assigned to this class or
group and belonged to data sets with a data set
organization other than VSAM. This value only
includes space allocated by data sets still
residing on primary DASD (no HSM data).
VSAM Megabytes Allocated
The total amount of allocated space found in the
input data that was assigned to this class or
group and belonged to data sets with a VSAM data
set organization. This value is expressed in
millions of bytes (megabytes), and only represents
data sets residing on primary DASD (no HSM data).
H-Migrate Megabytes Allocated
The total amount of allocated space found in the
input data that was assigned to this class or
group and was allocated by data sets that had been
migrated to HSM level 1 or level 2 volumes.
H-Backup Megabytes Allocated
The total amount of allocated space found in the
input data that was assigned to this class or
group and was allocated to HSM backup storage.
This value may include multiple backups of the
same data set.
