Diccache.dat

Diccache.dat is a cache file used by Siebel server programs to enhance performance when loading the Siebel Repository. Diccache.dat contains a subset of the repository (called the "dictionary") needed by the server programs. This subset includes information about tables, columns, indexes and docking objects.
 
Diccache.dat, located in the SIEBSRVR_HOME\bin directory, 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 The file is automatically recreated if the file does not exist or if it is out of date (The version number of the schema and repository is stored in the header of the file).
 
Dicdata.dat is a copy of diccache.dat file that is downloaded to mobile clients and used by the synchronization process whenever transactions are applied to the local database. It is the same as the diccache.dat file, but it is named differently for mobile clients. The Generate New Database component copies the diccache.dat to the dbtempl\\dicdata.dat file. When a mobile client synchronizes, the dicdata.dat is copied to the siebel_client_root\\dicdata.dat on the client machine.
