Abstract

Methods, computer program products, and systems are presented. There can be provided inputting a set of test transactions into a shadow production system, wherein providing of a set of test transactions includes modifying of a set of transactions of a production system, and obtaining a result of the inputting.

First claim

What is claimed is:

1 . A method comprising:
performing, by one or more processor, a first input of a set of test transactions into a shadow production system and a second input of the a set of test transactions into the shadow production system, the first input occurring prior to a software upgrade of the shadow production system, the second input occurring after the software upgrade of the shadow production system; and comparing, by the one or more processor, a result of the first input and the second input.

2 . The method of claim 1 , wherein the comparing includes comparing output message results of the first input and the second input.

3 . The method of claim 1 , wherein the comparing include comparing unloaded database content results of the first input and the second input.

4 . The method of claim 1 , wherein the comparing includes comparing CPU execution time results of the first input and the second input.

5 . The method of claim 1 , wherein the comparing including comparing output message results, unloaded database results and CPU execution time results of the first input and the second input.

6 . The method of claim 1 , further comprising inputting, by the one or more processor, a set of test transactions into the shadow production system, wherein providing of the set of test transactions includes modifying of a set of transactions of a production environment, and obtaining, by the one or more processor, a result of the inputting.

7 . The method of claim 6 , wherein the modifying includes ordering the set of test transactions based on an order of commitments of a database log.

8 . The method of claim 6 , wherein the modifying includes editing one or more transaction.

9 . The method of claim 6 , wherein the modifying includes performing, by the one or more processor, a pre-test by inputting one or more test transaction to determine a formatting error of the one or more transaction.

10 . The method of claim 1 , wherein the method includes initially setting a system time of the shadow production system to a time of commitment of a first transaction of a set of successive test transactions, and wherein inputting of a certain transaction of the set of successive test transactions includes: (a) determining if a current system time is earlier than the time of commitment of the certain transaction; and (b) if yes, holding an inputting of the certain transaction until the system time is equal to or later than the commitment time for the certain transaction and then perform the certain transaction.

11 . The method of claim 1 , further comprising inputting, by the one or more processor, test transactions into the shadow production system, wherein the inputting includes feeding first and second test transactions into the shadow production system on a one test transaction at a time basis, and obtaining, by the one or more processor, a result of the inputting.

12 . The method of claim 1 , further comprising inputting, by the one or more processor, test transactions into the shadow production system, wherein the inputting includes initially setting a system time of the shadow production system to a time of commitment of a first transaction of a set of successive test transactions, and wherein inputting of a certain transaction of the set of successive test transactions includes: (a) determining if a current system time is earlier than the time of commitment of the certain transaction; and (b) if yes, holding an inputting of the certain transaction until the system time is equal to or later than the commitment time for the certain transaction and then perform the certain transaction; and obtaining, by the one or more processor, a result of the inputting.

13 . A system comprising:
a memory; one or more processor in communication with the memory; and program instructions executable by the one or more processor via the memory to perform a method for controlling display of an image on a display screen, the method comprising: performing a first input of a set of test transactions into a shadow production system and a second input of the a set of test transactions into the shadow production system, the first input occurring prior to a software upgrade of the shadow production system, the second input occurring after the software upgrade of the shadow production system; and comparing a result of the first input and the second input.

14 . The system of claim 13 , wherein the comparing includes comparing output message results of the first input and the second input.

15 . The system of claim 13 , wherein the comparing include comparing unloaded database content results of the first input and the second input.

16 . A computer program product comprising:
a computer readable storage medium readable by one or more processing unit and storing instructions for execution by the one or more processing unit for performing a method, the method comprising: performing a first input of a set of test transactions into a shadow production system and a second input of the a set of test transactions into the shadow production system, the first input occurring prior to a software upgrade of the shadow production system, the second input occurring after the software upgrade of the shadow production system; and comparing a result of the first input and the second input.

17 . The computer program product of claim 16 , wherein the comparing includes comparing output message results of the first input and the second input.

18 . The computer program product of claim 16 , wherein the comparing include comparing unloaded database content results of the first input and the second input.

19 . The computer program product of claim 16 , wherein the comparing includes comparing CPU execution time results of the first input and the second input.

20 . The computer program product of claim 16 , wherein the comparing including comparing output message results, unloaded database results and CPU execution time results of the first input and the second input.
