The dcmakeup command must be used in order to reserve the OS resources that OpenTP1 uses to perform its internal control. When the dcmakeup command is executed, as many resources as necessary are reserved and stored under the OpenTP1 directory. How many resources to be reserved is analyzed on the basis of the system definition information under the OpenTP1 directory.

If the value of the prc_process_count operand in the process service definition is changed, the dcsetup command must be executed. Before executing the dcstart command, the dcmakeup command must be executed.

If the dcmakeup command is not executed before the dcstart command, the process by this command will be run when OpenTP1 begins but it may take much time to reserve resources many enough to perform complete internal control.
