Function: This report allows users to define a series of
data set name mask patterns, compare those
patterns against their existing data set names,
assign a group name when a match occurs, and then
summarize the data based on that group name. This
particular report gives a summary of each of the
assigned groups, including the number of data sets
that would exist in the group, and the amount of
space allocated and used by those data sets.
Further information about the use of pattern files
is available in the facility instructions at the
end of this section.
Benefit: Many software products allow generic patterns or
masks to be defined that are then used to assign
processing groups to the data set based on the
results of the pattern matching. This report will
help users define, test, and tune those patterns
and groups so that software can be implemented
faster and with fewer problems. These types of
patterns and groups are very common in both
automated data management software and in data
security products.
Features: Because of the complexity of pattern testing, an
assembler language format routine is called to do
the actual testing. This routine allows single
character masks (%), multiple character masks (*)
and multiple node masks (**).
SMS
Issues: This report is useful for identifying the data set
pattern masks that should be coded in SMS ACS
routines for the purpose of assigning class and
group names for new data sets. Once the pattern
file is complete, a report option can be used to
generate a starter or skeleton ACS routine.
COLUMN DESCRIPTIONS
Construct Name Assigned
The name of the construct for which this
summarization applies. A construct name may,
optionally, be associated with each search pattern
in the pattern file. The concept of constructs
allows many data sets with similar requirements to
be grouped as one logical entity. For example,
the following entries in the pattern file:
**.COBOL SOURCE
**.ASM SOURCE
**.PLI SOURCE
would assign data set names ending in the suffixes
COBOL, ASM and PLI to a common group known as
'SOURCE'. Because these data sets all probably
represent source code, it is logical that they
have similar requirements and can be treated as
one entity. Depending on the type of ACS routine
being written, the construct name could represent
the name of a Data class, Storage class,
Management class, or Storage Group. A value of
'(NONE)' in this column indicates that no
construct name was assigned, either because one
was not defined in the pattern file, or because
the data set matched none of the search patterns.
Data Sets Assigned to Group
The number of data sets within the input data that
matched search pattern and were assigned the
construct name represented by this summary line.
Percent Assigned to Group
The percentage of data sets within the input data
that were assigned to the construct name
represented by this summary line. Note that data
sets excluded from the analysis by filtering
criteria are not included when calculating this
value.
Megabytes Allocated The amount of storage space,
expressed in millions of bytes (megabytes),
allocated by the data sets assigned to this
construct.
Percent Space Allocated
The percentage of the total storage space
allocated by the data sets assigned this
construct, expressed in millions of bytes
(megabytes). This is calculated by dividing the
space allocated for this group by the total space
allocated by all data sets in the analysis. Note
that data sets excluded from the analysis by
filtering criteria are not included when
calculating this value.
Megabytes Used
The amount of storage space, expressed in
millions of bytes (megabytes), used by the data
sets assigned to this construct. Note that data
sets included from tape and HSM will always have
this value equal to the allocated value (unless
you use the PRIMARY option for HSM space
reporting).
Percent Space Used
The percentage of the total storage space used by
the data sets assigned to this construct,
expressed in millions of bytes (megabytes). This
is calculated by dividing the space used for this
group by the total space used by all data sets in
the analysis. Note that data sets excluded from
the analysis by filtering criteria are not
included when calculating this value.
