Passing Joins to DB2 under UNIX and PC Hosts

For a multiple-libref join to pass to DB2, all of these components of the LIBNAME statements must match exactly:
  • user ID (USER=)
  • password (PASSWORD=)
  • update isolation level (UPDATE_ISOLATION_LEVEL=, if specified)
  • read_isolation level (READ_ISOLATION_LEVEL=, if specified)
  • qualifier (QUALIFIER=)
  • data source (DATASRC=)
  • prompt (PROMPT= must not be specified)
