+**Note:** Raising the values of these parameters may cause HAWQ to request
more shared memory. To mitigate this effect, consider decreasing other
memory-related server configuration parameters such as
[gp\_cached\_segworkers\_threshold](../reference/guc/parameter_definitions.html#gp_cached_segworkers_threshold).
-1. Log into the HAWQ master host as the HAWQ administrator and source the
file `/usr/local/hawq/greenplum_path.sh`.
-2. Set the value of the `max_connections` parameter. This `hawq config`
command sets the value to 100 on all HAWQ instances.
- ``` bash

+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.
