The operation commands that can be used have the following restrictions:

• Operation commands executable in offline mode must be executed after termination of OpenTP1s both in the running and standby systems. The dcstart command can be executed, independently of either system status, if OpenTP1 for the machine is not in operation. For OpenTP1 in standby system, specification of the -n option of the dcstart command (forced normal termination) is ignored if the command is executed.
• An operation command executable in the online mode can be executed on online-mode OpenTP1 in the running system. Only the dcstop command with its -f option specified (forced termination) and the jnlunlfg command with its -n or -f option specified (unload journal files) can be executed for OpenTP1 in standby mode.
