Changes in topology
In a distributed server environment, the dmgr node contains the master configuration files. Each node has its required configuration files available locally. Configuration updates should be done on the dmgr node. The dmgr process then synchronizes the update with the node agent. File synchronization is a one-way task, from the dmgr to the individual nodes. Changes made at the node level are temporary and will be overridden by the master configuration files at the next file synchronization. If security is turned on, HTTPS is used instead of HTTP for the transfer.
File synchronization
File synchronization settings are customizable by cell. Each cell can have distinct file synchronization settings. File synchronization can be automatic or manual:
Automatic
We can turn on automatic synchronization using the Integrated Solutions Console. The default file synchronization interval is 60 seconds and starts when the appserver starts.
Manual
We can perform manual synchronization using the Integrated Solutions Console, wsadmin, or using the syncNode command located in the <install_root>/bin directory of the note being synchronized.
The file synchronization process should coincide with the whole change management process. In general, we recommend that we define the file synchronization strategy as part of the change management process.
