Initialization Process - IBM CICS Interface for Teradata

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.
