Abstract

PURPOSE:To constitute the system so that another designated OS (operating system) can be operated from each OS by providing a reading means for plural OS's, an OS switching request receiving means, a control means and a control information saving means for the OS which is currently operated, etc. CONSTITUTION:By a plural OS reading-in means 1, plural OS's which are desired to operate on the same system are read in at the time of start of the system. Subsequently, from the OS which is being operated, an OS switching request for designating the name of the OS to be operated in the next time is received through an OS switching request receiving means 2, or a request of the system end is received. When the received request is an OS switching request, an OS control information saving means 4 which is being operated is executed and control information of the OS which is being operated is saved, and subsequently, an OS control information resetting means 5 is executed and control information of the OS to be operated in the next time is reset. Next, an OS continuation operating means 6 is executed, and by switching from the OS which is being operated, a transfer operation to the OS which is desired to operate in the next time is executed. In such a way, the other designated OS can be operated from each OS.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a command-type operating system switching method for switching and operating a plurality of operating systems in a computer system.

[Conventional technology]

Conventionally, this type of operating system (hereinafter referred to as O8
In the switching method (referred to as ``controller O8''), switching between a plurality of O8s operating on the same system is performed using a control O8 that can switch the operation of the plurality of O8s.

[Problem to be solved by the invention]

The conventional command-type operating system switching method described above uses a control O8 that can switch the operation of multiple O8s, and the operating O8 specifies the next O8 to operate and switches the O8. There was a problem in that it was not possible to use a control method that would do this.

An object of the present invention is to provide a command-type operating system switching method that allows each O8 to operate a designated other O8.

[Means to solve the problem]

The command-type operating system switching method of the first invention is a command-type operating system switching method for switching and operating a plurality of operating systems in a computer system, the method comprising: (A) a plurality of operating systems that load the plurality of operating systems; a system reading means; (B) from among the operating systems read by the plurality of operating system reading means;
Operating system switching request receiving means for receiving an operating system switching request specifying a first operating system to be operated next and requesting switching to the first operating system from a second operating system in operation; C) an operating system control information storage means for storing control information of the second operating system; (D) storing control information of the first operating system to be operated next after switching from the second operating system described in H. (E) operating system continuation operation means for causing the first operating system to perform a takeover operation from the second operating system; When an operating system switching request is accepted by the operating system switching request receiving means, the operating system switching request is received from the second operating system.
The operating system is configured to switch to the specified first operating system.

Further, a command-type operating system switching method according to a second invention is a command-type operating system switching method for switching and operating a plurality of operating systems in a computer system, comprising: (A) a first method for loading a plurality of operating systems; (B) Operating system switching, which specifies a first operating system to be operated next from among the operating systems loaded in the first step, and requests switching to the first operating system. a second step of accepting a request from the second operating system; (C) a third step of saving control information of the second operating system; (D) switching from the second operating system. a fourth step of restoring control information of the first operating system to be operated next; (E) a fifth step of causing the first operating system to perform a takeover operation from the second operating system; , when the operating system switching request is received by the operating system switching request receiving means from the second operating system, the operating system switching request is received from the second operating system.
The operating system is configured to switch to the specified first operating system.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

The command type operating system switching method shown in FIG.
O8 switching request receiving means 2 for accepting switching requests; O8 control information storage means 4 for storing control information of the operating O8;
It is composed of an O8 control information restoration means 5 for restoring the control information of the next O8 to be operated, an O8 continuation operation means 6 for causing the next O8 to take over the operation from the currently operating O8, and a control means 3 for controlling each of the above-mentioned means. ing.

Next, the operation will be explained.

FIG. 2 is a flowchart showing the operation of the command type operating system switching method shown in FIG.

By multiple O8 reading means 1, at the time of system startup,
Load multiple O8s that you want to operate on the same system (Sl), then select the O8 to be operated next from the currently operating O8.
An O8 switching request specifying eight people is accepted via the O8 switching request receiving means 2, or a request for system termination is accepted (S2). It is determined whether the request received in S2 is for system termination (S3), and if it is for system termination, the system is terminated. If the request received in S2 is an O8 switching request, execute the operating O8 control information storage means to save the control information of the operating O8 (S4), execute the O3 control information restoration means 5, and then The control information of the O8 to be operated is restored (S5). And O8 continuous operation means 6
is executed to perform a handover operation from the currently operating O8 to the next O8 to be operated (S6).

In this way, by using the command type O8 switching method in which each O8 operating on the same system issues an O8 switching request as a command, each O8 can operate a specified other O8.

〔Effect of the invention〕

As explained above, the present invention uses a command-type operating system switching method in which each O8 operating on the same system issues an O8 switching request as a command.
This has the effect that each O8 can operate a designated other O8.
