The Teradata program, DBCCICS, performs the following initialization stages:

  1. Establishes a routine to trap and handle interface abends.
  2. Enables the task end/exit routine.
  3. Initializes the free storage chains as specified in the control block HSHSPBC (optional).
  4. Loads the single-shared copy of the CLI and preprocessor runtime.
  5. Waits for requests to freemain memory from transactions using the interface.
  6. Waits for a request from DSCN to shut down the interface.
  7. Starts the 2PC (two-phase commit) connections to TDPs whose entry in the DBCDLT specify START = YES.
