BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of restoring a database when a CAD system fails.

[0002]

2. Description of the Related Art Conventionally, when a CAD system fails, there have been a method of recovering data from an operation calculation record for a database and a method of directly recovering data from an operation record recording an end user's operation. The method of recovering the data from the record of operation calculation on the database is
It is a method used exclusively for data recovery, and CAD
The operation calculation for the database when the system is used is recorded and the data is restored based on the record. The system is restarted after data recovery. The method of directly recovering the data from the operation record that records the operation of the end user is also used for system demonstrations, etc., and it can be used for all end user operations including character editing and mouse movement locus. The system is restored by recording it in advance and reproducing it.

[0003]

However, the conventional method for recovering from a failure in the CAD system has the following problems. According to the method of recovering the data from the record of the operation calculation on the database, since the state change of the system other than the database cannot be reproduced, the data recovery is easy, but the failure analysis and the like are difficult. In addition, according to the method of directly recovering data from the operation record that records the end user's operation, all temporary operations that do not affect the system state such as character editing and mouse movement miracles can be reproduced. . Therefore, it took time to restore the system.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a recovery method in the event of a CAD system failure for analyzing a failure in the CAD system and recovering a database as follows. ing.
That is, while the CAD system is in use, a recording process of extracting a user's operation that causes a state change to the database and recording it in an operation record file is performed, and when the failure occurs, the user's operation stored in the operation file is recorded. Based on the record of the operation, the CAD system is activated to reproduce the user's operation until the failure occurs.

[0005]

According to the present invention, since the method for recovering from a failure in the CAD system is configured as described above, the recording operation allows the user's operation that changes the state of the database It is recorded in the recording file. When a failure occurs, the CAD system is started based on the record of the user's operation stored in the operation file, so that the user's operation until the failure occurs is reproduced. Therefore, the above problem can be solved.

At 133, the main processing unit 10 checks whether the value of the command menu indicates a figure registration command. When the value of the command menu is the graphic data registration command, the main processing unit 10 calls the graphic data registration processing of the graphic data management unit 73 in step S134. In step S135, the main processing unit 10 checks whether the received command menu value is the end command. When the end command is indicated, the main processing unit 10 ends the process. When the value of the received command menu indicates another command, the main processing unit 10 proceeds to step S13.
At 6, the figure is input and edited according to the command.

The CAD system of FIG. 1 operates in accordance with the processing of each of the above parts to record the user's operation after the graphic data registration in step S134 in FIG. 13 in the operation recording file 61. When a failure occurs in this CAD system, the operation recording file 61 is copied to the operation reproduction file 51 at the time of abnormal termination, and the system is started, so that after the step S131 of the main processing unit 10, the CAD system continues until the failure occurs. The operation of is automatically reproduced. At the time of this reproduction, since the mouse movement or the editing of the fixed form is not reproduced, this CAD system enables high-speed reproduction. Here, if the operation reproduction file 51 prepared in advance is the same as the operation recording file 61 at the time of failure occurrence, even the failure can be reproduced, so that failure analysis can be performed, and the operation recording file at the time of failure occurrence is also possible. If the data is reproduced by excluding the last one record in 61, the system can be restored to the state immediately before the occurrence of the failure. As described above, in the present embodiment, the processing results of the coordinate input unit 21, the format input unit 31, and the command input unit 41 are stored as operation record data.
Only the user's operation that changes the state of the database is extracted and recorded in the operation recording file 51. Therefore, when the system is restored, high speed reproduction is possible. Further, the system can be started based on the data recorded in the operation recording file 51, and the cause analysis of the failure occurrence can be easily performed. The present invention is not limited to the above embodiment, and various modifications can be made. For example,
If necessary, a method of storing information such as editing of a fixed format in the operation recording file 61 and reproducing it may be used.

[0016]

As described in detail above, according to the present invention, a recording process for extracting a user operation that causes a state change in a database and recording it in an operation record file is performed and stored in the operation file. Since the CAD system is started based on the record of the user's operation and the user's operation until the occurrence of the failure is reproduced, failure analysis in the CAD system can be performed and recovery after the failure of the system can be speeded up. it can.
