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.
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.

Response |
Node Crashes 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. Refer to: Server
Recovery - Market Data Loader.docx Server Specific Recoveries. |
1) Refer to: Server Recovery -
Market Data Loader.docx Server Specific Recoveries. 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.
