Remote data sharing group requirements

When an application requests data from a remote data sharing group, the Db2 for z/OS® requester searches the CDB for information about the remote group. Db2 uses the CDB to store information about how to communicate with remote groups, and the DDF uses the CDB to map Db2 location names and location aliases to IP addresses.

Group access requires:

  • A Db2 location name entry in the SYSIBM.LOCATIONS table
  • An entry in SYSIBM.IPNAMES table with the group DVIPA and any outbound user authentication requirements

Member-routing access requires:

  • Location alias entries in the SYSIBM.LOCATIONS table
  • An entry in SYSIBM.IPNAMES table with the group DVIPA and any outbound user authentication requirements
  • Optionally, location alias member entries in the SYSIBM.IPLIST table if you use subset location aliases

Single-member access requires:

  • A location alias entry in the SYSIBM.LOCATIONS table.
  • An entry in SYSIBM.IPNAMES table with the group DVIPA and any outbound user authentication requirements
  • A location alias member entry in the SYSIBM.IPLIST table
