APP22 Recovery (APP01/APP02/APP03)

 

                APP22 Purpose:

The APP22 process group is comprised of three separate application service types: APP01, APP02 and APP03.

Together, these service types read inbound market data from SITE 1 and SITE 2via MDP processes and load the data into the databases.

 

APP01 Processes read SITE 1 and SITE 2BBO Duration data from MDP (APP10/APP12) processes and load it into databases via database loaders.

APP02 Processes read SITE 1 and SITE 2Lastsale data from MDP (APP11/APP13) processes and load it into databases via database loaders.

APP03 Processes read SITE 1 and SITE 2Quote Montage data from MDP (APP10/APP12) processes and load it into databases via database loaders.

APP22 Recovery Considerations:

                                Stopping/Restart Processes:

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

-          Use APP22 nodes only when moving between nodes.  (APP22 processes utilize a lot more diskspace than other applications)

-          APP22 processes do not have DR nodes defined; These processes do not move between data centers. 

-          Restart these processes as quickly as possible on alternate nodes.  The longer the processes are down, the worst impaAPP11 we will have on Post Trade Processing.

 

 

APP22 NTM Control Commands:

See Application Recovery - DBL Binary.docx for more details.

There are no APP01, APP02 or APP03 specific NTM Control Commands outside of Binary Database Loader commands.

Evidenced by:

-          In EMT, applications report lost communications to APP22s

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

 

For APP01, APP02 and/or APP03:

-Post trade processing will not include all quote related market data.

2)      Restart affected APP22 processes on alternate nodes.

3)      Notify Management and PTT.

 

                           

APP22 Monitoring Considerations:

See Application Recovery - DBL Binary.docx for more details.

There are no APP01, APP02 or APP03 specific monitors outside of EMT and the Binary Database Loader monitors for each.
