"Diccache.dat" and "Dicdata.dat" File

"Diccache.dat" file is used by the Siebel server to increase the performance when loading the Siebel Repository. It contains a subset of the Siebel Repository which is called as the Dictionary which has information about columns, tables, indexes and docking objects.  This file is accessed whenever a server program is started. The file is automatically recreated if the file does not exist or if it is out of date. The version number of the repository and schema is stored in the header of the file.
