Preparations

Before using GaussDB(DWS), make the following preparations:

When creating a GaussDB(DWS) cluster, you need to specify a port for SQL clients or applications to access the cluster.
If your client is behind a firewall, you need an available port so that you can connect to the cluster and perform query and analysis from the SQL client tool.
If you do not know an available port, contact the network administrator to specify an open port on your firewall. GaussDB(DWS) supports port numbers between 8000 and 30000. By default, a data warehouse cluster is created with port number 8000.
After a cluster is created, its port number cannot be changed. Ensure that the port specified is available.
