APP18 Recovery (Firm Message Reader)

 

                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.

-          In Solarwinds (and outlook), node and processes will be reported down.

 

-Post trade processing will not include APP01 and APP02 MESSAGING data.
