25.4.2 Notes
- Depending on the SQL statement that is executed, more ports will be required than the calculated target value.
- If the number of ports allocated automatically by the operating system is insufficient, respecify the number in the pd_registered_port operand.
- When HiRDB releases port numbers, the OS does not necessarily release the numbers immediately (TIME_WAIT status). Therefore, the system will sometimes temporarily use a larger number of port numbers than the target number.
- If the system has a large maximum number of concurrent connections (pd_max_users), specify 1 in the PDTCPCONOPT client environment definition in order to reduce the number of ports that UAPs use to connect to HiRDB. For details about the PDTCPCONOPT client environment definition, see the manual HiRDB Version 8 UAP Development Guide.
