Configure deployment managers for a single, central point of administrative control for all elements in a WebSphere Application Server distributed cell.
If you plan to change the system clock, stop all the application servers, the node agent servers, and the deployment manager server first. Once you stop the servers, change the system clock, and then restart the servers. If you change the system clock on one system, ensure the clocks on all systems that communicate with each other and have WebSphere Application Server installed are synchronized. Otherwise, you might experience issues, such as security tokens no longer being valid.
Deployment managers are administrative agents that provide a centralized management view for all nodes in a cell, as well as management of clusters and workload balancing of application servers across one or several nodes in some editions. Each cell contains one deployment manager.
A deployment manager hosts the administrative console. .
When you create a deployment manager profile, a deployment manager is created. You can run the deployment manager with its default settings. However, you can change the deployment manager configuration settings, such as the ports that the process uses, custom services, logging and tracing settings, and so on.
