- Updating the Global Knowledge Base
  HCL provides monthly updates to the Global Knowledge Base (GKB) so that you can keep your product inventory definitions up-to-date. You can also submit items to HCL support for inclusion in GKB updates.
- Collecting scanned libraries with the Inquisitor for z/OS
  The Inquisitor is a program that scans and collects information about partitioned data set (PDS) and partitioned data set extended (PDSE) program libraries. The Inquisitor Import program takes the collected data as input to form the basis of your software inventory.
- Collecting UNIX files with the Inquisitor for z/OS UNIX
  The Inquisitor for z/OS® UNIX™ is a program that collects information about executable software existing in HFS and zFS data sets currently mounted and accessible to z/OS UNIX. The Inquisitor Import program takes the collected data as input to form the basis of your z/OS UNIX software inventory.
- Collecting usage data with the Usage Monitor
  The Usage Monitor is a server address space that runs as a started task. Work is queued to the Usage Monitor from all address spaces where programs are used. The Usage Monitor moves captured program usage data into the collection repository and periodically writes the accumulated data to a sequential file. The Usage Monitor runs APF authorized and is non-swappable.
- Importing Inquisitor data
  The Inquisitor Import reads data from Inquisitor scans, where the data is filtered and matched to products. The filtered, matched data is then copied to the Repository tables where it can be viewed and queried by the Analyzer reporting utility.
- Importing usage data
  The Usage import job imports data generated by the Usage Monitor and aggregates usage data for discovered or identified modules in the Repository tables in the database.
  - TPARAM parameters
    The TPARAM parameters that you specify for Usage Import define what data is included in the import.
- Aggregating usage and discovery data
  The Aggregator is a program that populates the Asset tables.
- Activating the Automation Server
  The Automation Server discovers new data sets and processes them by starting a set of predefined actions that associate the data with data set name masks that form a catalog search. This search determines if any data set names matching the mask are to be processed.

Importing usage data

The Usage import job imports data generated by the Usage Monitor and aggregates usage data for discovered or identified modules in the Repository tables in the database.

The HZASUIMP job in the JCLLIB library performs the Usage import. This job is generated from the HZASCUST post-installation customization job. Because run-time for this job depends on the volume of usage data to load, run this job during off-peak periods.

Usage data files can be either outputs from the Usage Monitor or condensed outputs from the ZCAT utility. These output files can be concatenated as a single input in the job. When you are priming a new repository, use a single small file as input when loading usage data for the first time.

If the HZASUIMP job processes the same data that is generated by the Usage Monitor for a specified system, the job terminates with an error to indicate that the input file is a duplicate input file.
