Because you must run certain commands and perform certain task steps on the head node
host, you might need to identify the head node host first.
Procedure
-
Issue the following Docker or Podman command:
docker exec -it Db2wh status
podman exec -it Db2wh status
-
In the IBM Db2 Warehouse Cluster Status section of the output,
look for the head node.
Sample output
follows:
root@node0101-fab - dashDB /]# status
