APP18 Purpose:
The APP18 process reads MESSAGING messages received from APP01 and APP02 processes and loads the data into the databases via loaders.
APP18 Recovery
Considerations:
Stopping/Restart
Processes:
-
Use NTM Control Utility - Service Control -
Process Controller to stop/restart processes.
- Use APP18 nodes only when moving between nodes. (No real dependencies outside of expected processor.)
APP18 NTM Control
Commands:
There are no APP18 specific NTM Control Commands outside of Binary Database Loader commands.

-Post trade processing will not include APP01 and APP02 MESSAGING data. Refer to: Bookfeed Retransmission Server Server Specific Recoveries. |
1) Refer to: Bookfeed Retransmission Server Server Specific Recoveries. 2) Restart affected APP18 processes on alternate nodes. 3) Notify Management and PTT. |
