RECOVERY SYSTEM FOR DEADLOCK INVALID DATA

Title:

RECOVERY SYSTEM FOR DEADLOCK INVALID DATA

Document Type and Number:

Japanese Patent JPS60171541

Kind Code:

A

Abstract:

PURPOSE: To attain a deadlock data recovery system by using a memory data backout processing means, a static point informing means and an output data backout means when a deadlock is produced.

CONSTITUTION: A program A5 attains the data recovery when a deadlock is produced. The transaction data is fed to complete the processing if no data exists. While the transaction processing is carried out based on the contents of the data if exists. In this case, a data base access is carried out. The result of this access is held by the memory data in a program. At the same time, the interface data is delivered to an interface file 9 for a program B6. These data are not effective as long as a deadlock is produced. Thus a memory data backout processing means 1 is used to perform the recovery of the memory data. Then a static point informing means 2 is used to fix the possibility of recovery for the data delivered to the file 9.
