Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a computer-implemented method for providing information on updates and/or fixes to a software product.

2. Description of the Related Art

When a software product is released, documentation is generally provided describing the functions and operations of the software. Before the next release of the software product, the producer may provide interim updates and/or fixes for the software product. These updates and/or fixes between releases are referred to as program temporary fixes (PTFs).

Often, there are several PTFs between major releases of the software product. Users may be unaware that PTFs have been installed and how they modify the software product. Further, the updates and fixes installed to the software product by way of PTFs are not described in the original documentation provided with the release of the software product. Moreover, separate documentation provided with a PTF is often lost, discarded or not readily available. As a result, at any given time, there is no way for the user to immediately determine exactly what changes have been made to any given copy of the software product, how those changes affect the functions and operations of the software product, and which sections of the original documentation are outdated. Furthermore, multiple copies of a product may be installed that are at unknown and/or different fix levels. Thus, there is a need in the art for improved methods of providing informational text or documentation concerning PTFs applied to the software product to users with the copy of the product they are using.

SUMMARY OF THE INVENTION

To overcome the limitations in the prior art described above, and to overcome other limitations that will become apparent upon reading and understanding the present specification, the present invention discloses a method, apparatus, and article of manufacture for providing information to a user on modifications made to a base software product with a program temporary fix. One or more program temporary fixes are applied to the base software product. The program temporary fix includes informational text describing how the program temporary fix modifies the base software product. The informational text included with the program temporary fix is applied to informational text provided with the base software product to generate cumulative informational text. The cumulative informational text describes the base software product as modified by the program temporary fix. The cumulative informational text may be accessed and presented to the user.

In further embodiments, the program temporary fix can comprise at least one update or fix to the base software product. In yet further embodiments, a second program temporary fix can be applied to a cumulative software product comprised of the base software product and the program temporary fix previously applied. In such case, the second program temporary fix would include informational text describing how the second program temporary fix modifies the cumulative software product.

An object of the present invention is to allow the user to readily access information describing the effect of installed PTFs on the base software product. Another object of the present invention is to provide a tool for accessing and presenting such information. Still another object of the present invention is to make the base software product and the applied PTFs self-describing entities. Yet another object is to consolidate information in a readily accessible location so users do not need to contact technical support facilities of the software developer or spend considerable time searching for technical support information in different locations.

Program Temporary Fixes

FIG. 2 is a block diagram that illustrates elements of the base software product 28 and the PTFs 30 and 32 that are used to modify certain functions and operations in the base software product 28 . In this example, the base software product 28 includes program functions 36 A, B, C, and D, as well as release information 38 describing the program functions 36 .

Sometime after the release of the base software product 28 , the software developer may provide PTF-1 30 . The installation of PTF-1 30 modifies the program functions 36 A and C of the base software product 28 with updates 40 A 1 and C 1 . The PTF-1 30 also provides fixes 42 F 1 , F 2 , and F 3 that correct various bugs and problems in the base software product 28 . PTF-1 30 further includes informational text 44 describing the updates 40 and fixes 42 and their effect on the base software product 28 , as well as providing updates and corrections to the release information 38 . Thus, after the user installs PTF-1 30 , the base software product 28 includes program functions 36 A 1 , B, C 1 , and D.

Sometime after the release of PTF-1 30 , the software developer may also provide PTF-2 32 . The installation of PTF-2 32 updates the program functions 36 A 1 , B, C 1 , and D of the base software product 28 with updates 46 A 2 , B 1 , C 2 , and D 1 . PTF-2 32 also provides fixes 48 F 1 ′, F 3 ′, and F 4 that correct various bugs and problems in the base software product 28 or in previous corrective service. PTF-2 32 includes informational text 50 providing updates and corrections to the informational texts 38 , 44 , as well as a description of the cumulative effect of both PTF-1 30 and PTF-2 32 on the base software product 28 . Informational text 50 may modify or replace release information 38 and/or information 44 provided with PTF-1 30 . Some parts of the informational text 38 , 44 prior to the application of informational text 50 may be valid and other parts may be outdated. Nevertheless, the net effect when displaying information after the application of informational text 50 is that the cumulative corrections are more accurate than all information contained within previous informational texts 38 , 44 . After a user has installed PTF-1 30 and PTF-2 32 , the base software product 26 includes modified program functions 36 A 2 , B 1 , C 2 , and D 1 and the most accurate accompanying information.

The Application Program

A user relying on the release information 38 provided with the base software product 28 may discover that, after the installation of PTF-1 30 and PTF-2 32 , the base software product 28 does not operate as described in the release information 38 because of the updates 40 , 46 and fixes 42 , 48 added by PTF-1 30 and PTF-2 32 , respectively. For example, the description in the release information 38 of functions 36 (A, B, C, and D) may no longer be accurate because of the modified program functions 36 (A 2 , B 1 , C 2 , and D 1 ) now present in the base software product 28 , which modifications were made by way of PTF-1 30 and PTF-2 32 . Moreover, the fixes F 1 , F 1 ′, F 2 , F 3 , F 3 ′, and F 4 may also have altered the base software product 28 to operate in a manner not described in the release information 38 .

A user would invoke the application program 34 to access information, resulting from the culmination of informational texts 38 , 44 , and 50 , on the base software product 28 and all fixes and updates implemented through the application of PTF-1 30 and PTF-2 32 . This informational text resulting from the culmination of informational texts 38 , 44 , and 50 includes, but is not limited to, the following descriptive information:

an identifier for the present version of the base software product 28 , including which PTFs 30 and 32 have been added;

what functional capabilities have been added, enhanced or removed from the base software product 28 ;

how the installation of the PTFs 30 and 32 alters the operation of the base software product 28 described in the release information 38 ;

updates that have been applied to the base software product 28 ;

fixes that have been applied to the base software product 28 ; and

which sections of the release information 38 provided with the base software product 28 (and any previously installed PTFs) are inapplicable or enhanced as a result of applying PTF-1 30 and PTF-2 32 to the base product 28 .

When invoked, the application program 34 accesses and extracts the informational text 38 , 44 , and/or 50 and then makes the extracted information available to the user. The application program 34 may provide an option for printing or displaying the informational text 38 , 44 , 50 , or for storing the informational text 38 , 44 , 50 in a user selected location for later use. In further embodiments, the application program 34 may include a search feature that allows the user to search or select the informational text 38 , 44 , 50 and any portions thereof. In this way, the user can immediately obtain information on the base product 28 as modified by the PTFs 30 , 32 and how the base software product 28 has been changed as a result of adding the PTFs 30 , 32 .

In preferred embodiments, the application program 34 may be invoked as a standalone program or it may be invoked as a module of an installation program (not shown) or in other ways known in the art. Alternatively, in embodiments where the application program 34 is embedded in the base product 28 , the application program 34 may be invoked from the user interface of the base product 28 . The application program 34 may include commands or invocation arguments that allow the user to specify whether to extract, display, search, print, and selectively save the information 38 , 44 , 50 .

Flowchart

FIG. 3 is a flowchart illustrating the logic used to apply the PTFs to the base software product. Such logic may be implemented in the software of the base product 28 and any PTFs 30 , 32 applied thereto. Those skilled in the art will recognize that this logic is provided for illustrative purposes only and that different logic may be used to accomplish the same results.

Block 52 represents the computer 8 initiating the installation of the PTF program (e.g. either PTF-1 30 or PTF-2 32 ), which includes any updates and/or fixes to the functions 28 and release information 38 of the base product. The PTF program may be installed by service personnel, the user or automatically during log-on/initialization. From block 52 control proceeds to block 54 which represents the computer 8 applying any updates 40 , 46 and fixes 42 , 48 included in the installed PTF 30 , 32 to the base software product 28 . The PTFs 30 , 32 would further apply informational text 44 , 50 to the available informational text describing how the PTF modifies the base software product 28 . If a subsequent PTF is applied, such as PTF-2 32 , then the subsequent PTF would modify the base software product 28 as modified by any previous PTFs and the release information 38 as modified by informational texts added during previous PTF installations. This yields a cumulative software product 28 and accompanying information that incorporates the base product 28 and all previous PTF modifications thereto.

From block 54 , control proceeds to block 56 which represents the computer 8 executing the application program 34 to access the informational text 38 , 44 , 50 from the base product 28 and/or PTF 30 , 32 . The application program 34 can be invoked even if a PTF has not been applied in order to access the release information 38 . From block 56 , control proceeds to block 58 which represents the user invoking the display 18 of a user interface of options to display, print, extract, store or search informational text 38 , 44 , 50 , or exit the application program 34 . Those skilled in the art will appreciate that in alternative embodiments a display 18 would not be used to display options to the user. Instead, the user would enter a command to display, print, store or search informational text 38 , 44 , 50 , or exit the application program 34 .

From block 58 , control proceeds to block 60 which is a decision block representing the computer 8 determining whether the user has elected to display, print, search, extract or store informational text 38 , 44 , 50 , or exit options. If so, control proceeds to block 62 ; otherwise back to block 60 to await user selection of an option. Block 62 is a decision block representing the computer 8 determining whether the user has requested to exit the application program 34 . If so, control proceeds to block 64 ; otherwise block 66 . Block 64 represents the computer 8 exiting the application program 34 . Block 66 represents the computer performing the user requested display, print, extract, store or search options. From block 66 control proceeds back to block 58 .
