2.18.1 Usage Guidelines

 
DATA SOURCE
-----------
The Tape Data Set Resource Planning Sample Application
processes data from the CA MICS Tape Analyzer Option. The TLM
component provides IT management information for tape data
set ownership and usage.  The TMCTMD file provides a daily
snapshot of tape data set characteristics and is used as
input into the sample application. This file contains
detailed information about each tape data set managed by the
tape management system. At summarized timespans, the data set
name and volser are dropped, but the summarization key
provides enough granularity to track and forecast tape data
sets at the Tape Library Management (TAPELIB) and Volume
Group (VOLGROUP) levels.

The capacity planner sample application creates a capacity
database containing a subset of CA MICS elements that reside
in the TMCTLM file. With this database, an analyst can track,
forecast, and report on tape-related characteristics like
these:
 
o  Tape Data Set Size
o  Tape Data Set Age
o  Last Used in Days
o  Encryption
o  Space Charges

CAPAPUs
-------
The application workload group (CAPAPU) data elements let you
group your individual tape library systems or volume groups
into logically similar workloads for meaningful tracking and
forecasting.  By default, CAPAPU is set to TAPELIB, and
CAPAPU2 is set to VOLGROUP. You have the ability to redefine
all CAPAPUs using the CAPAPU Derivation SAS Statements option
on the Extended Options Menu.


COMPOSITE HOUR
--------------
Raw data for the TLM component is collected by the TMCC
collector. The best practice is to run a TMCC raw data
collection once daily to provide a daily snapshot of the tape
data sets managed by the library. Because of this, the
Composite Zone/hour/day option defaults to Y. This summarizes
all zones, hours, or day names into a single observation,
masking the time at which the TMCC collector ran.
