APP31 Recovery (APP USE Service Bridge Process)

APP31 Purpose:

The APP31 process reads order and trade related messages from APP03 and writes them to APP04s.

The APP31 process reads order and trade related messages from APP04s and writes them back to originator.

APP31 Recovery Considerations:

Stopping/Restart Processes:

- Use NTM Control Utility - Service Control - Process Controller to stop/restart processes.

- Use APP31 nodes only when moving between nodes. (No real dependencies outside of expected processor.)

APP31 NTM Control Commands:

There are no APP31 specific NTM Control Commands.

APP31 Troubleshooting Table:

APP31 Symptom	Impacts	Response
Node Crashes Evidenced by: - In EMT, applications report lost communications to APP02 service. - In Solarwinds (and outlook), node and processes will be reported down.	-IBs will not be able to send orders to APP04s, and APP04 responses will be stopped. -CSI trade corrections will not be able to be sent to APP04s. Refer to: Server Recovery - Opcon APP03 CSI DCSR.docx Server Specific Recoveries.	1) Refer to: Server Recovery - Opcon APP03 CSI DCSR.docx Server Specific Recoveries. 2) Restart affected APP02 processes on alternate nodes. 3) Notify Management and PTT.

Node Crashes

Evidenced by:

- In EMT, applications report lost communications to APP02 service.

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

-IBs will not be able to send orders to APP04s, and APP04 responses will be stopped.

-CSI trade corrections will not be able to be sent to APP04s.

1) Refer to:

Server Specific Recoveries.

2) Restart affected APP02 processes on alternate nodes.

3) Notify Management and PTT.

APP31 Monitoring Considerations:

There are no APP31 specific monitors outside of EMT and related ME and APP03 monitors.
