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.

The table below 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.

Table G-2 Number of additional concurrent connections for each command (XDS commands) shows the XDS commands. Determine the appropriate values if you use a memory database.
