Mobile Phone Patent Description
FIELD OF THE INVENTION

The invention relates to the field of computing, and more particularly to platforms capable of remotely sensing and healing applications and other software installations.

BACKGROUND OF THE INVENTION

Software failures, faults and inconsistencies on both the application and operating system (OS) sides exact a price on computer users, network administrators and others. Applications may crash due to run-time errors, hardware updates and incompatibilities and other issues. An operating system may hang or fail to deliver expected services due to driver conflicts, conflicting updates, security breaches and other issues. In any case, a variety of types of software faults stress the user support systems of many software vendors. This may be particularly the case in larger or more complex network sites, such as sites utilizing enterprise server or other clusters. For these sites several hours of telephone consultation may be required to fix software faults encountered by users.

Some software applications have incorporated updating or healing features. Microsoft Corp.'s Office.TM. suite for instance is equipped with certain self-repair features, including an ability to detect the deletion of significant associated files which are then automatically reinstalled. The Microsoft WindowsXP.TM. operating system for its part may alert a user when OS updates become available, through Internet or other connectivity. However, the WindowsXP.TM. repair function is not entirely automatic, in that it does not retrieve necessary updates over the Internet or other connectivity directly. That operating system instead builds a directory of pending or possible patches which the user then manually chooses to install. A user moreover may not program the OS or application update service to filter out, automatically install or otherwise process software fixes according to flexible criteria. Other problems exist.

SUMMARY OF THE INVENTION

The invention overcoming these and other problems in the art relates in one regard to a system and method for active diagnosis and self healing of computer software systems, in which one or more software applications along with the operating system of a client or other computing device may be continuously monitored for current and prospective software errors, and be automatically subjected to software refreshes to be healed and updated without user intervention. In embodiments, the application suite as well as operating system of a client device may be registered to a remote server which monitors the client device for software faults and other anomalies. When an application or OS crash or other fault occurs, that event may be trapped and an inquiry made against a knowledge base or other resource to determine a potential fix. That solution may be automatically delivered to the malfunctioning client, or in cases the user may select between possible fixes or elect to uninstall problem software or take other remedial action. In embodiments, the user of a client device may adjust or program the triggering events and other conditions of the self healing facility, for example to exclude simple memory errors from attempted fixes, inhibit fixes until a certain number of repeated faults have occurred, or apply other criteria or conditions to the self correction action.

As illustrated, ADSH server engine 116 may include a user mode service 118, which may be generally directed to application support, and a kernel mode service 120, which may be generally directed to operating system support. Other services or categorizations are possible. In embodiments, the ADSH service may reside or execute on a support server 122, or other dedicated host or other system. The ADSH server engine 116 may for instance communicate with the client 102 over communications link 110 using dedicated or dynamic transfer control protocol or other port assignments, or other communications channels or mechanisms. The support server 122 may be or include, for instance, a workstation running the Microsoft Windows.TM. NT.TM., Windows.TM. 2000, MacOS.TM., Unix, Linux, Xenix, IBM AIX.TM., Hewlett-Packard UX.TM., Novell Netware.TM., Sun Microsystems Solaris.TM., OS/2.TM., BeOS.TM., Mach, Apache, OpenStep.TM. or other operating system or platform.

In embodiments, the client 102 may communicate with the ADSH server engine 116 to cooperatively monitor for software faults, failures and other conditions which may require remedial or other action. The client 102 may so communicate with the ADSH service on a continuous, periodic, triggered episodic or other basis, depending on network configuration and other factors. For instance, a user of client 102 may install an update to an application in the client application set 106. Upon launching that updated application, the client 102 may encounter a printing fault which prevents documents or files from printing to a printing device. The operating system 128 of client 102 may trap that print fault, and communicate a machine state image 130 of client 102 to the ADSH server engine 116.

The machine state image 130 may contain a snapshot of the state of one ore more of the subject application causing a fault, other software or components, hardware profiles including drivers, and other information representing processes and resources active at the time of the detected fault, or otherwise. In embodiments, the delivery of machine state image 130 may not necessarily be conditioned on the occurrence of a software or other fault, but instead may be performed periodically or otherwise as a maintenance or other measure.

Support server 122 may receive the machine state image 130 from client 102, and identify the source or sources of an existing execution fault. In embodiments, support server 122 may maintain an application support set 124 containing one or more individual applications APP.sub.1, APP.sub.2 . . . APP.sub.M (M arbitrary). Application support set 124 may represent a library of applications which may be registered to the ADSH server engine 116 as eligible for maintenance and healing services, according to the invention. In embodiments, the application support set 124 may contain a variety of productivity, utility, communications or other applications, from one or more vendors or sources.

In embodiments, support server 122 may also maintain a resource support set 126 containing one or more individual resources RES.sub.1, RES.sub.2 . . . RES.sub.N (N arbitrary). Resource support set 124 may represent a library of operating system or other system or other resources which may be registered to the ADSH server engine 116 as eligible for maintenance and healing services, according to the invention. In embodiments, the resource support set 126 may contain hardware drivers such as video, audio, printer, storage device or other peripheral or other drivers, BIOS code or settings, or other code or resources supporting the operation of clients registered to the ADSH server engine 116. In embodiments, the resource support set 126 may contain an indication whether a given individual resource is certified by the vendor of operating system 128 or otherwise for compatible operation, or contain other data regarding client resources.

Upon receipt of the machine state image 130, the ADSH server engine 116 may check the offending application or other process requiring diagnosis or attention against the application support set 124 and resource support set 126 to determine whether that application or process is valid and eligible for support according to the invention. If not, a message may be communicated to client 102 to indicate that automated diagnostic support is not available for the component causing the failure or other condition.

For applications, resources or other components which are validly registered to the ADSH server engine 116, the ADSH server engine 116 may identify the application, resource or other component necessitating a fix to determine possible software updates, patches or other healing or maintenance action. In embodiments, the ADSH server engine 116 may communicate with one or more knowledge base 114 to test for recorded instances of the particular type of fault or condition. ADSH server engine 116 may likewise communicate with knowledge base 114 via communications link 110, or in embodiments may communicate via dedicated or other direct or indirect channels. In embodiments, the registration and continued support of ADSH server engine 116 may be on a paid or unpaid subscription basis, or other bases.

For instance, in embodiments, if the ADSH server engine 116 determines that an update to a word processing application has caused an incompatibility with an existing printer driver loaded on client 102, the ADSH server engine 116 may perform a lookup in knowledge base 114 to determine a quick fix engineering (QFE) or other solution to the fault. In embodiments, the solution may involve the downloading, for example, of a more current printer driver or other resource, an update or patch to the application causing the crash or other fault or other condition, or other data from the knowledge base to the client 102.

In embodiments, the ADSH service may likewise communicate with a vendor base set 112 containing one or more vendor bases BASE1, BASE2 . . . BASE.sub.X (X arbitrary) which may be or include application, update, driver or other local or remote databases or resources for particular applications from particular vendors to extract fixes and solutions for a specific fault.

In embodiments, knowledge base 114, vendor base set 112 and other storage resources may be configured according to standard database schema standards, to enhance the compatibility and interoperability of the ADSH service. This may be helpful, for instance, when more than one ADSH server or other engine accesses knowledge base 114, vendor base set 112 or other storage resources. The content of knowledge base 114, vendor base set 112 and other storage resources may be indexed or numbered according to standard schema or specifications, to increase the efficiency of searches and other operations on the content of those resources. Schema in which knowledge base 114, vendor base set 112 and other storage resources may be configured include, for example, object-based models such as the ODMG standard (2.0 or other) promulgated by the Object Database Modeling Group, or other object-based or non-object based specifications. Object-based schema may permit binding to or through a variety of programming interfaces, such as XML, C++, Java and others. Knowledge base 114, vendor base set 112 and other storage resources may in embodiments be, include or interface to extensible or configurable database and other resources, such as standard query language (SQL) and other platforms.

Knowledge base 114, vendor base set 112 and other storage resources may likewise be, include or interface to, for example, the Oracle.TM. relational database sold commercially by Oracle Corp. Other databases or platforms, such as Informix.TM., DB2 (Database 2), Sybase.TM. or other data storage or query formats, platforms or resources such as OLAP (On Line Analytical Processing), a storage area network (SAN), Microsoft Access.TM. or others may also be used, incorporated or accessed in the invention. Knowledge base 114, vendor base set 112 and other storage resources may be supported by server or other resources, and may in embodiments include redundancy, such as a redundant array of independent disks (RAID), for data protection.

In embodiments, the machine state image 130 may reflect complex or multiple software conditions or faults, for which direct resolution through knowledge base 114 or other platforms may not be feasible. In such cases, the ADSH client 104 may present the user of client 102 with further alternatives, such as reverting to prior versions of applications, drivers or other resources, contacting a support line, or taking other action.

Diagnostic and related processing according to an embodiment of the invention is illustrated in FIG. 2. In step 202, processing may begin. In step 204, client 102 may establish communications with ADSH server engine 116. In step 206, one or more individual applications in client application set 106 or client resource set 108 may be registered to ADSH server engine 116. In step 208, a user may operate the ADSH client 104 to select activation criteria 132 or otherwise program or configure desired diagnostic and self healing services, according to the invention.

In step 210, the client 102 may trap an occurrence of a software fault or other condition to report to ADSH server engine 116, for instance by isolating that fault or condition in the operating system 128. In embodiments, the trapping of a fault or other condition may include the generation of a machine state image 130, or recording other data. In step 212, a machine state image 130 or other data reflecting that fault or condition may be communicated to the ADSH server engine 116. In step 214, the ADSH server engine 116 may examine any one or more of the support application set 124, resource support set 126, service log 136, knowledge base 114, vendor base set 112 or other databases or resources to determine if a matching solution to the fault or condition is found.

If no matching solution is found, processing may proceed to step 216, where a user notification, for instance by dialog box or otherwise, may inform the user that an automated solution has been attempted but not found. In embodiments, the user may subsequently be presented with further options, such as an option to try an automated repair again later, an option to select a manual repair, or others. After the notification of step 216, processing may proceed to step 230 and end, repeat, return to another processing step or perform other action.

If a matching solution to the pending fault or condition is found in step 214, processing may proceed to step 218 where a solution may be communicated to client 102. In step 220, the user may be presented with a dialog box or other notification that a solution is available. In step 222, the user may be presented with options to execute the solution, such as for instance to perform an automatic install, defer installation, revert to manual installation or other alternatives. In step 224, the solution may be executed on client 102. In step 226, the ADSH client 104 may reboot the client 102, restart an application or take other steps to complete the solution. In step 228, the ADSH client 104 may determine whether proper execution of the solution has occurred. If continued or additional faults occur, in step 230 processing may return to step 212. If the fault or other condition has been resolved, processing may proceed to step 232 where processing may end, return to another step, repeat or perform other action.

In embodiments, the application, driver or other update, patch or other resource generated in the solution may be communicated directly from knowledge base 114 or vendor base set 112 to client 102, or may be communicated from ADSH server engine 116 itself or otherwise to the client 102. The client 102 may present an ADSH client 104 to a user to manipulate the receipt and other operation of diagnostic and healing activity on client 102. For instance, the ADSH client 104 may inform a user, via a popup dialog box or otherwise, that a printer or other error has been detected and a driver or patch has been automatically retrieved to attempt to resolve the fault. In embodiments, the ADSH client 104 may permit the user to select between accepting the fix, storing but not implementing the fix, ignoring the fix, or taking other actions. The ADSH client 104 may communicate the user's selected solution back to the ADSH server engine 116, for instance to log the corrective actions to a user profile for future access or correction. ADSH client 104 may in embodiments be interoperable with other software, for instance via application programming interfaces (APIs) or other techniques.

ADSH client 104 may likewise present a user of client 102 with options to configure and maintain the diagnostic and self-healing service operating on that machine. As illustrated in FIG. 3, for instance, a user may program or select a set of activation criteria 132 which govern the activation of fault reporting and other functions of ADSH server engine 116, according to user preference. For instance, the activation criteria 132 may include a threshold filter for certain types of faults or errors, which inhibit the ADSH server engine 116 until selected conditions are met. For example, a user may program the activation criteria 132 to require that memory leak or other memory-related errors reach a certain size, before triggering an attempt at automatic diagnosis. Or, memory type errors could be ignored entirely. For further example, a user might require that an error, such as an application fault, occur a specified number of times before invoking ADSH server engine 116. Other conditions, triggering events, error severity or criteria may be selected as part of activation criteria 132.

In embodiments, besides servicing individual requests for diagnostic and healing on client 102 or other devices, the support server 122 may also track and analyze historical sets of repair actions to develop statistical profiles of application, system resource and other behavior. In this regard, support server 122 may contain an analytic engine 134 communicating with service log 136, service log 136 recording actions taken by ADSH server engine 116 for one, many or all users of client 102 and other clients registered to ADSH server engine 116. This may permit, for example, ADSH server engine 116 to detect recurring faults or patterns to enable better repair or preventive actions.

For example, service log 136 may indicate that frequent instances of an application failure for a certain application, such as a graphics package, occur when a given video adapter is installed in a client machine. The ADSH server engine 116 may then determine whether an updated set of system resources 126, such as a video driver, or an available update in application set 124, such as a patch for that application, are available to remedy the problem. If so, then ADSH server engine 116 may add those or other fixes to knowledge base 114, or take other action. As illustrated in FIG. 4, in embodiments, systems administrators may also edit knowledge base 114 using an administrative interface 138, for example to add or modify the knowledge base 114 with updated applications, drivers, error conditions and other data. The administrative interface 138 may in embodiments permit a systems administrator or other user to query the service log 136, knowledge base, vendor base set 112, client 102 and other resources or components to operate and maintain the ADSH server engine 116.

In embodiments, ADSH server engine 116 may proactively deliver or "push" the graphic package, driver or other generated fixes to client 102 or other client devices having the identified combination of problem hardware and software, to prevent compatibility problems from developing. In embodiments, if such a proactive delivery is scheduled, the ADSH client 104 may query the user whether they wish to accept automated downloads on that basis, or defer the download, decline the fix or take other action.

The foregoing description of the invention is illustrative, and modifications in configuration and implementation will occur to persons skilled in the art. For instance, while the invention has generally been described in terms of a standalone client 102 whose installed applications and resources are registered to and maintained by ADSH server engine 116, in embodiments more than one machine, or a local area or other networked group of machines, may be individually or collectively registered to the ADSH server engine 116 and controlled through client 102 or another central administrative machine, or by one ore more other clients or channels.

Similarly, while the knowledge base 114 has generally been described in terms of a single database resource, in embodiments the application, system and other resources described as being stored on knowledge base 114 may be distributed across one or more local or remote databases. Other hardware, software or other resources described as singular may in embodiments be distributed, and similarly in embodiments resources described as distributed may be combined. The scope of the invention is accordingly intended to be limited only by the following claims.
