The product database refers to an interrelated set of files named
    *.PCSI$DATABASE. These files ordinarily reside in SYS$SYSTEM.

    When you use this command, PCSI does the following:

    o  Reads *.PCSI$DATABASE files referenced by the root database
       file PCSI$ROOT.PCSI$DATABASE and checks all fields for correct
       syntax.

    o  Automatically performs minor repairs when a known corruption
       pattern can be identified and if a repair is feasible.

    o  Provides instructions for rebuilding the database if an
       unrecoverable corruption is found.

    The PRODUCT ANALYZE PDB command always reads the
    PCSI$ROOT.PCSI$DATABASE file, even if you also select a subset
    of the database files for analysis.
