The following facilities can be used to create RDAREAs:

• When HiRDB is first installed
  If you use either of the following environment setup support tools, RDAREAs can be created when you run the tool:
  
  • Simple setup tool
  • Batch file (SPsetup.bat) (Windows edition only)
  If you use a command to set up the HiRDB environment, you can use the following utility to create RDAREAs:
  
  • Database initialization utility (pdinit)
• When adding RDAREAs
  You can use either of the following utilities to create (add) RDAREAs:
  
  • Database structure modification utility (pdmod)
  • Registry facility initialization utility (pdreginit)

For details about RDAREA creation, see the HiRDB Version 9 Installation and Design Guide or HiRDB Version 9 System Operation Guide.

Hint

• Pay particular attention to the value of the pd_max_rdarea_no operand. This operand specifies the maximum number of RDAREAs. If the number of RDAREAs exceeds the value of this operand, you can no longer start HiRDB normally.
• For a HiRDB parallel server configuration, there are restrictions concerning the servers on which RDAREAs can be created, as shown in the table below. The figure following the table shows an example of an RDAREA configuration (for a HiRDB parallel server configuration).
