TBECMPCA is a utility for determining which compression algorithm to use for a data set or a group of data sets. This utility accepts a disk or tape data set as input and invokes each of the compression algorithms to compress the data set. The effectiveness of the algorithm (expressed as the percentage of compression) and the total number of microseconds it takes to compress the data is calculated for each compression algorithm. A report is created showing the results of each compression algorithm with a summary on the first page and a detail page for each compression algorithm. The report includes a recommended compression method on the summary page. This recommended method represents the ratio of the total time divided by the percent of compression.
You can also use this utility to provide detailed diagnostics for CA Technical Support if you encounter a problem with compression processing.
