The present invention relates to a recording medium that stores a download target file introduction processing program.

[0002]

2. Description of the Related Art Generally, when a file is downloaded from a server machine on an arbitrary network to a client machine under the server machine, a required download cannot be completed normally depending on a process operation state of the client machine. is there.

For example, if a predetermined file is downloaded from a server in a state where predetermined anti-virus software (so-called “vaccine software”) is resident on a client, the anti-virus is downloaded from the server. Scan the status of the file
Since the communication between the server machine and the client machine is intermittently interrupted, an error frequently occurs due to a time-out of a non-communication timer set on the server machine side.

A conventional method for coping with an error that occurs at the time of downloading a file due to the resident of anti-virus software in a client machine will be described below with reference to the accompanying drawings.

FIG. 2 is a diagram showing a conventional method of introducing a file to be downloaded together with its application system. In this figure, as a system to which the method for introducing a download target file is applied, a delivery target file distribution system for broadcasting from a central location a business application used in each branch of the company is shown.

As shown in FIG. 1, a delivery target file distribution system α to which the present download target file introduction method is applied includes a management server machine 11 in a delivery center 1 serving as a base of required file distribution, and A delivery server 31 in (a plurality of) branches 3 that are WAN-connected to the management server 11 through a frame relay network (hereinafter, referred to as an “FR network”) 2, and a LAN connection to the delivery server 31 in the branch 3 (Multiple) client machines 32.

In the above system configuration, first, the management server 11 in the delivery center 1 executes, for example, executable files prepared as update files (upgrade files) of business applications used by the client machines 32 in the branch 3, respectively. File [AAA. EXE],
Library file [BBB. DLL] and a data file [CCC. DAT] is compressed into one file (ST1), and the compressed file is delivered via the FR network 2 to the delivery server machine 3 in the branch 3
1 (ST2).

[0008] The delivery server machine 31 in the branch 3 decompresses the received compressed file, and delivers the original delivery target file, that is, the executable file [AAA. EXE], the library file [BBB. DLL] and a data file [CCC. DAT], and set them as download target files (ST
3).

Then, the client machine 32 in the branch 3
Executes “download pre-processing”, “download processing”, and “re-download processing” in response to a download request given from the delivery server machine 31 (ST4).

That is, the client machine 32 stops the business application as the software to be updated, which is the update destination of the file to be downloaded, as a pre-download process, and stops it. The executable file [AAA. EXE], the library file [BBB. DLL] and a data file [CCC. D
AT] and applies them to a form executable by the client machine 32.

Here, when predetermined anti-virus software is resident on the client machine 32, an error occurs for the above-described reason (the file to be downloaded has not yet been applied to the executable form). ) At this time, the delivery server machine 31 in the branch 3
Creates an error list (not shown) for the client machine 32 in which the error has occurred, and later remotely logs in to the client machine 32 (all the client machines in which the error occurred) specified in the error list, After stopping the execution process of the anti-virus software by remote control, the above error is dealt with by re-downloading the required download target file as a re-download process (after downloading the download target file, This applies to a form that can be executed in the client machine 32).

The above-mentioned processing in ST4 can be realized as a computer program, and the program is stored in either the delivery server 31 or the client 32 in the branch 3. . In addition, the program includes a delivery server machine 31
In response to the above-described download request given by the client device 32, it is loaded into a main memory (not shown) in the client device 32 and executed.

[0013]

As described above, in the conventional method of introducing a file to be downloaded, even if it is known in advance that anti-virus software is resident on the client machine 32, The download process of the required download target file is executed unconditionally.

For this reason, in order to cope with an error inevitably generated as a result of the execution of the first download process (download process), the download process must be executed again. There is a drawback that the introduction efficiency of the download target file is very poor.

Further, after the second download load process (re-download process) is executed to complete the introduction of the required download target file to the client machine 32, the resident of the anti-virus software remains released. Therefore, there is a disadvantage that the client machine 32 is not protected from the virus unless the user executes the restart processing.

Here, the main objects to be solved by the present invention are as follows.

That is, the first object of the present invention is to provide an anti-virus software which is resident on a client machine.
It is an object of the present invention to provide a download target file introduction method and a recording medium storing a download target file introduction processing program capable of surely introducing a download target file to a client machine without being affected by the above.

A second object of the present invention is to record a download target file introduction method and a download target file introduction processing program capable of efficiently introducing a required download target file to a client machine in a short time. No recording media will be provided.

A third object of the present invention is to provide a method for introducing a file to be downloaded and a method for introducing the file to be downloaded, which can automatically restart the anti-virus software upon a request from the delivery server after the introduction of the file to be downloaded is completed. It is intended to provide a recording medium on which a file introduction processing program is recorded.

Other objects of the present invention will become apparent from the description of the specification, the drawings, and particularly from the claims.
