PURPOSE:To realize simple transaction backout, and to realize an optimum recovery to a fault by adopting a system to return to the processing re-starting address of an application program through direct address designation after the restoration of the fault. CONSTITUTION:In a main program 3, task recovery routine using declaration and a first and a second return addresses are acquired. In the case of the error of data logic or the abnormal return of system macro, control is transferred to a transaction backout program 10. After the restoration of the fault, the control is returned directly to the designated first return address. In the case of the occurrence of a deadlock, the control is transferred to the program 10, and after exclusion is released, the control is returned directly to the second return address. In the case of the generation of program interruption, the control is transferred to the program 10 through OS, and returned to the first address. |
