APP15 Recovery (MESSAGING Service Router)

               

APP15 Purpose:

MESSAGING Service Routers receive MESSAGING related MESSAGING and MESSAGING from the APP02 (TXR) or from Clearing.

MESSAGING Service Routers send MESSAGING related MESSAGING and MESSAGING to appropriate order sending firms/vendors. 

 

MESSAGING Service Routes are configured such that:

-          the DC01 instance sends drop copies for DC01 APP02s,

-          the DC02 instance sends drop copies for DC02 APP02s.

APP15 Recovery Considerations:

                                Stopping/Restart Processes:

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

-          Use APP15 nodes only when moving between nodes.  (No real dependencies other than expected processing sites.)

 

-          When stopping/restarting APP15 processes:

1)      Notify the MESSAGING firms and vendors to notify them that drop copies will be interrupted.

2)      Stop/Restart the APP15 process.

 

APP15 NTM Control Commands :

-          There are no APP15 specific NTM Control Commands.

Response:

Processes facilitate communications from  APP02s (via TXR and APP15 processes) to Order Sending Firm's MESSAGING Destinations.

Monitor shows 29 West statistics (by topic) for DCSF processes, receiving from APP15 processes.

Data is RED.

Process is either down or multicast data is not being received by monitor.
1) Check status of process
2) If process is up, call Technical Services.

 

 

Rate and/or MsgCount values are not incrementing as expected.

Firms may not be receiving messages as expected.

2) Call Production Support if necessary.

 

 

 

By matching topic_name, Rcv MsgCount in this monitor does not match total Src MsgCount values in TXR_LBM Stats moniitor.

Firms may not be receiving messages as expected.
1) Check DCS FIX message files to confirm inbound messages and outbound messages.
2) Call Production Support if necessary.
