The maximum size of a HiRDB file system area is 2,047 MB (about 2 GB). To create a HiRDB file system area that is larger than this size, you need to create the HiRDB file system area as a large file. If it is created it as a large file, the maximum size of the HiRDB file system area is 1,048,575 MB.

• Method for creating a large file
  You can create a large file in the same manner as with a HiRDB file system area. Use the pdfmkfs command's -n option to specify the size of the HiRDB file system area that is to be a large file (2 gigabytes or greater).
  
• Files to be used with utilities
  The following utilities may not support large files:
  
  • Database load utility (pdload)
  • Database reorganization utility (pdrorg)
  See the manual HiRDB Version 9 Command Reference to determine whether these utilities support large files.
