• Creating a cluster subnet group.
• Listing metadata about a cluster subnet group.
• Modifying a cluster subnet group.
For step-by-step instructions to run the following example, see Running Java Examples for Amazon
Redshift Using Eclipse (p. 130).You need to update the code and provide a cluster subnet group name
and two subnet identifiers.
