Abstract

PURPOSE:To shorten an IPL time by integrating an OS program and an application program, treating them as a load module starting a system when IPL of a rised minimum part terminates. CONSTITUTION:When the system is rised, a central processing unit 10 loads a system file recorded in an IPL load device 18 in a main storage device 11 through a channel device 12, etc., when a reset starts and executes the file. A monitor which the system requires to a minimum is loaded and executed at first. The system rises by the execution of the monitor. The service of the application, etc., is not loaded yet. Then, the application program, etc., are succesively loaded. When TP as the test program requested by a user, for example, is not loaded, the program is preferentially loaded. Thus, the system can be raised at highspeed without loading all the application programs.

Description

[Detailed Description of the Invention] [Summary] The purpose of the present invention is to provide a system startup method for a computer in a switchboard that shortens the startup time and improves operability for workers. The application program is integrated into a single load module, and in the exchange that loads the load module at startup, the files that make up the system are divided into multiple parts, and the system is started when the IPL of the minimum startup part is completed. The configuration is configured so that the content is multiplied and loading is performed sequentially thereafter.

[Industrial application field]

The present invention relates to an information processing system such as a computer system, and more particularly to a method for starting up a computer system in an exchange.

[Conventional technology]

Information processing systems such as computers start up by importing programs and data from external devices, such as auxiliary storage devices. This program is usually called a system file and consists of O3 and applications. By changing the system file at the time of starting up this system, it is possible to realize a switching device having various switching functions, for example, and the usage can be changed depending on the user.

On the other hand, in an exchange, the aforementioned OS program and application program are integrated and linked, and one
It is handled as a book load module. Then, when turning on the power or starting up after a reset, this 1
After loading the book load module is running.

[Problem to be solved by the invention]

In the switching system described above, one load module is large. This loading is necessary when starting up this system. However, when starting up a system with a specific purpose of testing at the time of shipment, an application program may not be necessary.

In addition, since it is only needed in testing situations, it cannot be started until all applications (all test program data) have been loaded, which causes the problem that it takes a long time to start up the system. had.

SUMMARY OF THE INVENTION An object of the present invention is to provide a system startup method that reduces startup time and improves operator operability.

[Means for solving the problem and their effects] Divide the files that make up the system into multiple parts, manage the load modules of each divided system in divided units, and when the loading of the monitor part that does not include the application is completed. Start the monitor. Then, load the remaining divided system files that must be loaded sequentially. Since the monitor part is activated, the worker can input commands, and the appearance is as follows.
PL time is shortened. Further, after this point, that is, after only the monitor part has been started, when the user enters a command to execute an application program, and if the application program is not loaded, the startup may be refused. Alternatively, the functionality for the user can be further enhanced by placing the application program on hold or loading the application program preferentially.

〔Example] Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a system configuration diagram of the present invention, and FIG. 2 is a configuration explanatory diagram of an embodiment of the present invention. The switching system according to the embodiment of the present invention includes a central processing unit (CC) 10 and a main memory (
MM) 11 and channel device (CHC) 12 are connected. The main storage device 11 is a memory that stores programs or data to be executed by the central processing unit 10, and the channel device 12 is an Ilo that performs various controls such as data exchange and auxiliary storage. Channel device 12 has a serial interface adapter (SIA) 13.14
, a magnetic tape device (MTC) 15 is connected, and a console device 1 is connected to the serial interface adapters 13 and 14.
6, an MT device 17 and an IPL unit device (IPL load device) 18 are connected. When starting up this system, the central processing unit 10 connects the L
The IPL loading device 18 loads the stored system file into the main storage device 11 and executes it. This loading and execution are divided, and the monitors required by the system as a minimum are loaded and executed first. By running this monitor, the basic system starts up (however, services such as applications have not been loaded yet). Then, the aforementioned application programs and the like are sequentially loaded.

FIG. 2 is a block diagram of a second embodiment of the present invention.

As shown in the figure, in the second embodiment, the console device and the IPL load device 11B in the system configuration of FIG. 1 are also used. i.e. 5IA13.1
In addition, the console device 16 and the IPL load device 18 are the same device. When this system is started up and IPL is executed, the system program stored in the device 20 serving as an IPL unit and console is stored in the main storage device 23 via the SIA 21 and the channel device 22. At this time, the first program loaded is the monitor MON, and the central processing unit 24 immediately executes this monitor.

Then after the monitor XXITP, XX2TP, XXmT
P, ...The monitor performs the transfer request of XXnTP,
The table A-Table in the main storage device 23 is rewritten for those that have been loaded. That is, each time the loaded program is loaded, a flag is set to indicate that the loaded program has been loaded.

Meanwhile, while the XXmTP program is being loaded, the monitor receives and receives instructions from the operator. If a request to start a TP that has not yet been loaded is entered (if it has already been loaded, it will be executed as is), the instructed TPO loading will be executed with priority and the loading operation that was being executed at that time will be interrupted). Immediately after loading is completed, the loaded TP with priority is executed. When the prioritized loading is completed, the interrupted loading operation is resumed.

Through the above operations, if the user makes a request and the requested TP, for example a test program, is not loaded, that program is loaded with priority, so there is no need to load all application programs. The system can be started up quickly.

In other words, as shown in FIG.
mTP, . . . XXnTP is loaded, and then the monitor is executed and output such as messages is output. Then, it was possible to input a key to the monitor, and commands etc. could be input from this key. In contrast, according to the embodiment of the present invention, startup is started after the monitor is loaded, and a message (MSG) is output. XXITP and XX2TP are output simultaneously with this message output.

...The XXmTP programs are being loaded one after another.

At this time, the operator is naturally inputting a command for the next application program, etc., but this KEY input is slow compared to the loading speed. For example, if the command has already been loaded after the KEY input is finished, be able to do it. Also,
If it is not done yet, it can be prioritized or put on hold. Further, processing when the command is not loaded can be arbitrarily set, such as forcibly discarding the command without putting it on hold.

[Effects of the Invention] As described above, according to the present invention, it is possible to obtain a replacement device that can shorten IPL time and improve work efficiency.
