Remote data sharing group requirements

This section describes the requirements of member-specific, group-generic, and single-member access.

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

Member-specific access requires:

  • Location entries in the SYSIBM.LOCATIONS table
  • Conversational security requirements entries in the SYSIBM.LUNAMES table
  • LUNAMEs of the members to be accessed in the SYSIBM.LULIST table

Group-generic access requires:

  • A Db2 location name entry in the SYSIBM.LOCATIONS table
  • A conversational security requirements entry in the SYSIBM.LUNAMES table

Single-member access requires:

  • A location entry in the SYSIBM.LOCATIONS table. If you plan to allow group access concurrently with single-member or member-specific access, then the requester should use a server-defined location alias name in the SYSIBM.LOCATIONS table.
  • A conversational security requirements entry in the SYSIBM.LUNAMES table
  • The LUNAME of a single member in the SYSIBM.LULIST table
