Preparations

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

Determining the Cluster Ports

  • 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. The ports supported by GaussDB(DWS) range from 8000 to 30000.
  • After a cluster is created, its port number cannot be changed. Ensure that the port specified is available.
