Appendix G. Number of Concurrent Command Connections

Some commands (operation commands and utilities) perform connection processing internally in HiRDB. When you execute commands or determine the pd_max_users operand value in the system definition, you must note the following:

The connection frame specified in the pd_max_users operand is used at the time of command connection; therefore, the number of connections available to users is reduced temporarily.

If there are more command connections than the number of connections available in the connection frame at the time of a command execution, a connection error occurs and the command may result in an error.

Table G-1 shows the number of additional concurrent connections that are possible for each command. The provided number of concurrent connections is relative to there already being one command execution.
