importOverlayConfig.py script

When setting up a star topology, we 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.

Run the importOverlayConfig.py script from the deployment manager on CellA to link the overlay anchor transports of CellA to CellB.

./wsadmin.sh -profileName profile_name -f importOverlayConfig.py link path_to_CellB_overlaynodes.config_file

Run the importOverlayConfig.py script from the deployment manager on CellA to link the overlay anchor transports of CellA to CellC.

./wsadmin.sh -profileName profile_name -f importOverlayConfig.py link path_to_CellC_overlaynodes.config_file

Run the importOverlayConfig.py script from the deployment manager on CellB to link the overlay anchor transports of CellB to CellA.

./wsadmin.sh -profileName profile_name -f importOverlayConfig.py link path_to_CellA_overlaynodes.config_file

Run the importOverlayConfig.py script from the deployment manager on CellC to link the overlay anchor transports of CellC to CellA.

./wsadmin.sh -profileName profile_name -f importOverlayConfig.py link path_to_CellA_overlaynodes.config_file

Example

See the following example to unlink two cells.

./wsadmin.sh -profileName profile_name -f importOverlayConfig.py unlink path_to_target_cell_overlaynodes.config_file
