importOverlayConfig.py script
When setting up a star topology, we can use the importOverlayConfig.py script to configure the overlay communication between multiple cells.
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.
The importOverlayConfig.py script is in the app_server_root/bin directory.
The overlaynodes.config file is in the app_server_root/profiles/dmgr_profile/config/cells/cell 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.
Log on to CellA dmgr host to link the overlay anchor transports of CellA to CellB.
./wsadmin.sh -profileName profile -f importOverlayConfig.py link path_to_CellB_overlaynodes.config_file
Log on to CellA dmgr host to link the overlay anchor transports of CellA to CellC.
./wsadmin.sh -profileName profile -f importOverlayConfig.py link path_to_CellC_overlaynodes.config_file
Log on to CellB dmgr host to link the overlay anchor transports of CellB to CellA.
./wsadmin.sh -profileName profile -f importOverlayConfig.py link path_to_CellA_overlaynodes.config_file
Log on to CellC dmgr host to link the overlay anchor transports of CellC to CellA.
./wsadmin.sh -profileName profile -f importOverlayConfig.py link path_to_CellA_overlaynodes.config_file
Example
See the following example to unlink two cells.
./wsadmin.sh -profileName profile -f importOverlayConfig.py unlink path_to_target_cell_overlaynodes.config_file
