    +**Note:** Raising the values of these parameters may cause HAWQ to request more shared

the value to 100 on all HAWQ instances.

    +You will perform different procedures to set connection-related server configuration
parameters for your HAWQ cluster depending upon whether you manage your cluster from the command
line or use Ambari. If you use Ambari to manage your HAWQ cluster, you must ensure that you
update server configuration parameters via the Ambari Web UI only. If you manage your HAWQ
cluster from the command line, you will use the `hawq config` command line utility to set
server configuration parameters.
