Index scan utility

This section provides information about the capabilities and use of the optional Fast Path Indexer/EP scan (XSCAN) function. This function is executed by a command-driven utility that lets you scan a Fast Path primary DEDB to locate index source segments and then produce an output data set containing index information.

Note

All topics in this section apply to both PFX indexes and IBM native indexes, except where noted.

By using the command-driven XSCAN utility, you can scan a single area or multiple areas in a primary DEDB in offline or online mode.

Fast Path Indexer/EP executes an online scan in an interactive Fast Path (IFP) region.

Fast Path Indexer/EP provides the XSCAN command, the IX subcommand, and the associated keywords. The XSCAN command (when used with the IX subcommand and associated keywords) lets you scan a single area or multiple areas in a primary DEDB to locate index source segments for a defined index and then produce an output data set containing index information. This output data set can be used as input into the build, verify, and resynchronize (can only process PFX indexes) utilities.
