importOverlayConfig.py script
When setting up a star topology, you can use the importOverlayConfig.py script to configure the overlay communication between multiple cells.
Purpose
Use the importOverlayConfig.py script to enable communication between Intelligent Management cells. Each cell contains a overlaynodes.config file that must be copied between the cells to enable multi-cell performance management.
Location
The importOverlayConfig.py script is in the app_server_root/bin directory.
The overlaynodes.config file is in the app_server_root/profiles/deployment_manager_profile_name/config/cells/cell_name directory of each cell.
Example
See the following examples to configure the overlay communication between multiple cells. Consider a scenario in which there are three cells: CellA is the center cell, and CellB and CellC are the point cells.
./wsadmin.sh -profileName profile_name -f importOverlayConfig.py link path_to_CellB_overlaynodes.config_file
./wsadmin.sh -profileName profile_name -f importOverlayConfig.py link path_to_CellC_overlaynodes.config_file
./wsadmin.sh -profileName profile_name -f importOverlayConfig.py link path_to_CellA_overlaynodes.config_file
./wsadmin.sh -profileName profile_name -f importOverlayConfig.py link path_to_CellA_overlaynodes.config_file
Example
./wsadmin.sh -profileName profile_name -f importOverlayConfig.py unlink path_to_target_cell_overlaynodes.config_file
