File Organization

The table below identifies data elements by which the file is sequenced and summarized in each timespan. N/A indicates that the file is not supported in a timespan. At the DETAIL level, data is sequenced but not summarized.
The timespans in which a file is supported are defined by each installation when CA MICS is installed. Therefore, this table has been generated as part of the installation process to accurately reflect the CA MICS system at your installation.

Retrieval Examples

In the examples, a SAS macro variable is used to specify the DDname part of the CA MICS file name. These macro variables are a standard part of CA MICS and are available for all files. The macro variable name has the form &diiit, where d is the database identifier, iii is the information area name, and t is the timespan. For the example, a database identifier of P is used. The identifier is installation-dependent, so you should find out what the identifiers are at your installation.
  • Using the most recent DAYS timespan HVTHHA file, display a comparison between the amount of data and volumes in cache and the amount of data and volumes on physical tape.
