In this article we will cover, How to stop, start and deploy application. Also we will go through the steps on how to stop each component of DQ+ like Load Balancer, Application Servers, ApplicationDB and ComputeDB individually.
In DQ+ 2.1.1 and 2.1.2 the stop and start command stop/start all components, except ComputeDB (VerticaDB). In DQ+ 3.0 and later versions, the command will stop/start all components including ComputeDB.
(i) Complete Start/Stop of Application
(ii) Stop/Start Application components individually
(iii) Deployment of Application
(i) Complete Start/Stop of Application:
a- DQ+ 2.1.1 & 2.1.2
- Login into the Maintenance Node and switch to maintenance user (usually the user-name is “sagacity”).
- Change directory to /opt/infogix/sagacity-2.1/bin/
- Execute “./stop” command to stop all the Application components.
- To stop computeDB execute “./stopComputeDB”.
(./stop)
(./stopComputeDB)
(In a similar sequence, start the Application)
- Execute “./start” from same directory (/opt/infogix/sagacity-2.1/bin/)
- To start ComputeDB execute “./startComputeDB”
(./start)
(./startComputeDB)
(b) - DQ+ 3.0 and later version.
- Login into the Maintenance Node and switch to maintenance user (usually the user-name is “sagacity”).
- Change directory to /opt/infogix/sagacity-3.0/bin/
- Execute “./stop” command to stop all the Application components, include ComputeDB.
- To start the Application execute "./start" from same directory /opt/infogix/sagacity-3.0/bin/. (This will start all the Application component including ComputeDB)
Back to top
(ii) Stop/Start Application components individually.
To stop and start the individual system components, use the following commands. The commands are available under /opt/infogix/sagacity-3.0/bin
- Application Server
./stopApplication
./startApplication
- ApplicationDB
./stopApplicationDB
./startApplicationDB
- ComputeDB
./stopComputeDB
./startComputeDB
- Load Balancer
./stopLoadBalancer
./startLoadBalancer
(iii) - Deployment of Application
Changes in install.proeprties require re-deployment of an Application. Before re-deploying the Application, make sure all the components are running and functional.
- Go to /opt/infogix/sagacity-3.0/bin.
- As maintenance user execute "./deploy"
Note : In 2.1.1, and 2.1.2 Password-less sudo access of maintenance user is required for all above activities. However, in DQ+3.0 after Fix Pack 5 Password-less sudo access of maintenance user is not required.
