The following provides notes on duplication of the port numbers specified in HiRDB system definitions (the System common definition and Unit control information definition sections of Table 23-2).
- In a single unit, specify different port numbers in each operand.
- For HiRDB/Parallel Server, if you start multiple units on a single server machine, specify different port numbers in each operand of the respective units.
- If you start multiple units on the same server machine, specify different port numbers in each operand of the respective HiRDBs.
- If the same server machine has a HiRDB client and a HiRDB server, specify port numbers different from the client environment definition PDCLTRCVPORT in each operand.
- Specify port numbers that fulfill the following conditions.
- They are different from the port numbers used by other program products.
- They are different from the port numbers registered in %windir%\system32\drivers\etc\services (for a DNS environment, the location it defines)
- They are not included in the range of port numbers auto-allocated by the OS#
#: The range of port numbers auto-allocated by the OS differs from OS to OS.
- When no HiRDB port number is specified, 20000 is assumed for the HiRDB port number. For this reason, do not specify 20000 in an operand.
