Running utilities
HCL Z Asset Optimizer provides utilities that you run to perform routine functional tasks to maintain the product lifecycle.
Compressing and decompressing data sets with the HZAZIP utility
HZAZIP is a utility program that can compress a sequential or partitioned data set into a zip archive, decompress the contents of a zip archive into a sequential or partitioned data set, and report on the contents of a zip archive.
Text data processing
The HZAZIP utility processes text data to be compatible with the zip processing utilities available on other platforms.

Running utilities
HCL Z Asset Optimizer provides utilities that you run to perform routine functional tasks to maintain the product lifecycle.
- Condensing usage data with the ZCAT utility
  The ZCAT utility concatenates and condenses Usage Monitor data sets and generates a file that is then processed by the Usage Import program. When you condense the data produced by the Usage Monitor program, you can save storage space and improve the performance of the Usage Import program.
- Deleting usage data with the Usage Deletion utility
  Use the Usage Deletion utility to delete detailed, summarized, and aggregated usage data for a specified period for all systems in the repository. Each time you run the utility, usage data is aggregated to update the asset tables.
- Deleting a specific system with the System Deletion utility
  Use the System Deletion utility to delete discovery, usage, and hardware data for a specified system.
- Deleting obsolete data with the Physical Deletion utility
  Use the Physical Deletion utility to delete obsolete data that are no longer required.
- High-level qualifier listing
  HCL Z Asset Optimizer collects large amounts of usage data. The High-level Qualifier Listing for the Usage Monitor utility creates a list of high-level qualifiers for the products that are to be identified.
- Updating the TPARAM table
  The TPARAM table in the repository can be set to an inconsistent state due to failures in jobs that update the repository tables. You can reset a parameter in the TPARAM table to rectify this inconsistent state.
- Tagging unidentified products with the Product Tagging utility
  The Product tagging utility allows you to create local entries for your in-house software in the Local Knowledge Database. It is not intended for creating IBM or ISV software, as this may cause unpredictable results. If you need to add products or versions that are not being identified, then notify HCL Support, so that they can then update the GKB. On certain occasions, HCL Support may consider your request to add HCL or ISV software to the LKB database, but contact them first before doing so.
- Importing subcapacity reporting data with the SCRT Import utility
  The SCRT Import utility imports data (CSV files) which is generated from the IBM Subcapacity Reporting Tool.
- Capturing historical SMF data with the SMF Scanner utility
  You can run the SMF Scanner utility to get historical usage information from existing SMF data. This SMF data enables you to view trending results from before HCL Z Asset Optimizer is installed.
- Extracting data with the XML Export utility
  The XML Export utility extracts information in XML format that you can then import into IBM Control Desk (ICD).
- Compressing and decompressing data sets with the HZAZIP utility
  HZAZIP is a utility program that can compress a sequential or partitioned data set into a zip archive, decompress the contents of a zip archive into a sequential or partitioned data set, and report on the contents of a zip archive.
  - Text data processing
    The HZAZIP utility processes text data to be compatible with the zip processing utilities available on other platforms.
  - Binary data processing
    The HZAZIP utility processes binary data in order to preserve record boundaries, while other platforms typically consider binary data to be a byte stream without structure.
  - HZAZIP program parameters
    The HZAZIP utility can accept up to two program parameters. The first parameter specifies the function the program is to perform and the second parameter can provide a data definition override list for programs that dynamically invoke the utility.
  - HZAZIP files
  - Dynamic invocation by other programs
    Other programs can call the HZAZIP utility to perform compression and decompression processing requests. When the HZAZIP utility receives control, it examines the program parameter list and proceeds accordingly.
  - HZAZIP data set support
    The data control block (DCB) attributes of the original data set that the HZAZIP utility compresses are not encoded into the archive. The success of a compress and decompress cycle requires the user to supply suitable DCB attributes for the ultimate destination of the data.
  - HZAZIP return codes
    When you run the HZAZIP utility, several codes are returned that indicate whether the program ran successfully.
- Browsing zipped data
  Components such as the Inquisitor programs, the Usage Monitor, and the ZCAT utility deal with sequential data sets containing zip archives. Processing the data with a zip algorithm allows the same information to be conveyed in a fraction of the original size, but it does mean that browsing the file to quickly confirm the nature of its content becomes a more involved process.
- Browsing active collection data
  The Usage Monitor collects program usage information and writes out the collected data at least once each day. Once the data is in a data set, it is possible to browse it to determine if some expected usage was collected or not. Sometimes it would be advantageous to be able to determine if expected data collection has taken place without waiting for the collection cycle to end, either at the expected time or because it was triggered manually to facilitate data access.
- Verifying database changes since the product was released
  This utility verifies database changes that were introduced after the product was released.

Text data processing with the HZAZIP utility

The HZAZIP utility processes text data to be compatible with the zip processing utilities available on other platforms.

When compressing a text record, the HZAZIP utility performs the following processing:

Translates EBCDIC line feed (LF) characters (x'25') to periods.
Translates EBCDIC data to ASCII data.
Appends an ASCII carriage return line feed (CRLF) sequence (x'0D0A') to encode the record extent.
Compresses the data and writes it to the archive.

Each compressed member is marked as an ASCII text file, and the internal attribute value of the central file header is set to 1.

The following input data set attributes are also stored in the zip header extended field:

Data set organisation
Record format
Block size
Logical record length

When decompressing text data, the HZAZIP utility performs the following processing:

Accumulates data until an ASCII LF (x'0A') is encountered.
Truncates the trailing ASCII carriage return (CR) (x'0D') if present in accumulated data.
Translates the ASCII data to EBCDIC and writes the data as a single record.

During compression, records read from data sets with fixed-length records have their trailing blanks truncated before being compressed. After being decompressed, short records to be written to data sets with fixed-length records are extended with blanks to the required length.

The translation tables used for conversion between EBCDIC and ASCII that are originally sourced from the EZAESENU member in the SEZATCPX library are reciprocal, so that applying one translate table and then the other yields the original data. Consequently, all EBCDIC single byte character set (SBCS) and double byte character set (DBCS) text can undergo a ZIP and UNZIP cycle without corruption.
