Abstract:
A query plan modification system and method relate to a database system that includes a cost-based optimizer for generating access plans. The database system also permits a user to view an access plan that has been generated by a particular SQL query and modify the access plan if desired. The user specifies customizations that are associated with the access plan so that when that plan is executed, the customizations are executed as well. Exemplary customizations include specifying an initialization file specific to a query, specifying different implementation methods than those in the original access plan, prohibiting rebuilding of an access plan, and over-riding or ignoring a clause within the query that is used to generate the access plan.
Abstract:
A document and image management system that can manage handwritten comments and/or edits on conventional paper. The invention may be embodied as an enhanced photocopier adapted to locate and classify handwritten notations using optical character recognition techniques. This embodiment allows the user to select options to selectively copy only those pages with notations, to create an index of handwritten notations, to add side margin locator marks to the document, and to compare subsequent comments on different drafts.
Abstract:
Methods that utilize at least one prematurely terminated processing of a database query to improve the processing of the database query. The embodiments discussed track termination information associated with at least one user initiated premature termination of processing of a database query to improve the processing of the database query. Information related to the premature terminations of a database query may be utilized by a DBMS to generate and/or implement suggestions to improve the processing of the database query, resulting in improved query processing, improved performance, fewer premature terminations, and more satisfied users.
Abstract:
In an embodiment, a problem record associated with a query is saved to a log if the query encountered a problem. The amount of data in the record is increased if an access plan associated with the query has changed within a threshold amount of time and decreased if the access plan has not changed. In various embodiments, the problem is that the query executes longer than a historical average for the query, the query executes longer than a threshold, or the query encounters a functional error. In an embodiment, a benchmark record is also saved to the log, the problem record is compared to the benchmark record, and the difference is presented. In various embodiments, an oldest record is periodically removed from the log, or an oldest record is removed from the log if the associated query has more than a threshold number of records.

Abstract:
A database query optimizer allows specifying a performance specification for a query. When an access plan is created, the actual performance for executing the query using the access plan is determined and compared to the performance specification for the query. If the actual performance does not satisfy the performance specification for the query, the query optimizer autonomically generates a different access plan to see if the performance improves. If an access plan that meets the performance specification is generated, the new access plan is stored in the access plan cache for the query. If no access plan can be generated that meets the performance specification for the query, the access plan that provided the best performance is selected and stored in the access plan cache for the query.
Abstract:
A method, apparatus and computer program product are provided for implementing autonomic testing and verification of software fix programs or program temporary fixes (PTFs). A software fix program including multiple patches or a program temporary fix (PTF) including multiple programs is received. Each patch or program of the multiple patches or multiple programs of the software fix program or PTF is sequentially applied to a software product. The software product is tested responsive to each sequentially applied patch or program. Then next iterations or different combinations of patches or programs are sequentially applied to a software product and then the software product is tested responsive to each of the applied iterations.
Abstract:
A method, apparatus and computer program product are provided for identifying hypertext links in document printouts. A document to be printed is scanned for identifying local hypertext links within the document. A page location of each identified local hypertext links within the document is computed and stored. Printable objects are sequentially checked to identify each printable object within a hypertext anchor tag. Each identified printable object within a hypertext anchor tag is rendered with a predefined indication of the hypertext link. A local hypertext link is printed with a page number of the hypertext link within the document. An external hypertext link is printed with a uniform resource locator (URL) for the external hypertext link. Both the page number of the local hypertext link within the document and the uniform resource locator (URL) for the external hypertext link can be printed, for example, in superscript form and bolded or with other highlighting.
Abstract:
An apparatus and method helps a user to determine parts of an electronic document that are of interest by allowing the user to define preferences for processing an electronic document, and by automatically highlighting one or more portions of the document according to the user preferences. Highlighting includes any way to enhance or alter the appearance of text, including bold, italics, underlining, change in font style, change in font size, change in color, change in background color, etc. The automatic highlighting of portions of the document attract the user's eyes to that portion of the document, which helps the user to discern whether or not the highlighted portion is relevant or interesting. The preferred embodiments also include a document generator that takes an input document and generates therefrom an output document that has one or more highlighted portions that are hard-coded into the document according to the user preferences. The preferred embodiments further include the ability to automatically enable or disable the highlighting of a document according to characteristics of the electronic document, or the user's actions (such as the speed of scrolling through a document). In addition, the preferred embodiments include markup language tags that allow an author of a document to define portions of interest that may be highlighted when highlighting is enabled.
Abstract:
An apparatus and method define one or more events that run a Java script when a web page is bookmarked. In the preferred embodiments, a browser determines whether a requested web page was requested from a bookmark, whether the requested page is currently bookmarked, and whether the requested page is the browser's home page. This information is sent along with the page request so the web server can take appropriate action based on this information. One or more events are defined that each run a corresponding Java script to indicate when a page was loaded from a bookmark, when a page is bookmarked, when a page is not bookmarked, and when a page is the home page of the browser. The preferred embodiments allow bookmark information to be communicated to a web server, which can then use the bookmark information in a variety of ways. One preferable way to use the bookmark information is to vary the presentation of the web page depending on whether the page is bookmarked or not.
