When connection is established with a HiRDB at another node, the HiRDB version should be checked. The following points must be taken into consideration when the two HiRDB versions are different:

1. Only facilities supported by the earlier version of HiRDB are available.
2. Only data types supported by the earlier version of HiRDB are available.
3. If the return code from the distributed server is not listed in the current manual, see the appropriate manual for the distributed server's version.
