The processing of server pages is emulated at run time. The system includes a library of custom tags, and a server page emulator for reading the server page, including identifying any calls to the library of custom tags, and further for emulating any calls to the custom tags identified in the server page; and thereby generating and processing the server pages dynamically at runtime. Each server page is parsed to create a tree of nodes for each element of the page, and each node identified as one of template text, custom tag start, custom tag end, and expression language (EL) expression. For each template text node, text is written directly to final markup. For each custom tag node, a return code indicates that the body should be skipped, processed normally, or provided as bulk data to the tag implementation. For each EL expression node, the EL expression is evaluated and the result written to final markup.

System and computer program product for updating an SSL certificate for a server. First program instructions detect when a change has been made to a name, domain or IP address of the server and detect that the server is using an SSL certificate based on a name, domain or IP address applicable before the change. In response, the first program instructions notify an administrator that a change is required to the SSL certificate to reflect the change to the name, domain or IP address. Second program instructions respond to a request by the administrator, to automatically create a new SSL certificate signing request. The new SSL certificate signing request is a form which can be sent to an SSL certificate authority. Third program instructions respond to another request by the administrator, to send the new SSL certificate signing request to the SSL certificate authority. Fourth program instructions respond to receipt of a new SSL certificate from the SSL certificate authority and another request by the administrator, to substitute the new SSL certificate for the existing SSL certificate. Fourth program instructions query the administrator if the administrator wants to use a new self-signed SSL certificate reflecting the change to the name, domain or IP address of the server, until the new SSL certificate signed by the SSL certificate authority is received from the SSL certificate authority, and if so, generate the new SSL self-signed certificate. Other program instructions respond to a request by the administrator, to create a self-signed SSL certificate and substitute the self-signed SSL certificate for the existing SSL certificate.

Mapping of address space by providing real storage including first and second address spaces. The second address space is smaller than and contained within the first address space. Provided within virtual storage is a system execution space. Providing within the system execution space is a system execution area having a size equal to or less than the second address space. The system execution area includes a control program having a first portion capable of addressing the first address space and the system execution space, a second portion constrained to address only the second address space and the system execution area, and at least one alias page. Responsive to a control program request for a first page in the virtual storage, a first frame is assigned in real storage corresponding to the page. Responsive to a request from the second portion of the control program for the first page, allocating an alias page in the system execution area, the alias page backed by the first frame.

A system and method for a multi-modal browser/renderer that simultaneously renders content visually and verbally in a synchronized manner are provided without having the server applications change. The system and method receives a document via a computer network, parses the text in the document, provides an audible component associated with the text, simultaneously transmits to output the text and the audible component. The desired behavior for the renderer is that when some section of that content is being heard by the user, that section is visible on the screen and, furthermore, the specific visual content being audibly rendered is somehow highlighted visually. In addition, the invention also reacts to input from either the visual component or the aural component. The invention also allows any application or server to be accessible to someone via audio instead of visual means by having the browser handle the Embedded Browser Markup Language (EBML) disclosed herein so that it is audibly read to the user. Existing EBML statements can also be combined so that what is audibly read to the user is related to, but not identical to, the EBML text. The present invention also solves the problem of synchronizing audio and visual presentation of existing content via markup language changes rather than by application code changes.

A computer system for processing and committing data comprises a processor, an external storage device such as DASD or tape coupled to the processor, and a working memory such as RAM. An application program updates data in the working memory and then requests that the data be committed, i.e. written to the external storage device. In response, an operating system function determines which data or blocks have been changed and supplies to an I/O service an identification of the changed data or blocks to cause the I/O service to write the changed data or blocks to the external storage device. Thus, the application program is not burdened with the management of the I/O. The operating system permits the program to continue with other processing while the data is being written from the working memory to the external storage device. As a result, the program need not wait while the data is written to the external storage. Also, because little time is required of the program in the commit process, the program can frequently request commits. With frequent commits, there is less chance that the data will have been written to back-up memory or back-up storage (due to an overload of the working memory) between commits, and as a result, time will not be required to read the data from the back-up memory or storage into the working memory en route to the application program's external storage. Also, the frequent commits reduce the chance of overloading the I/O subsystem.

Computer system which supports asynchronous commitment of data

In a multi-processing computer system, a method for serializing references to shared data objects, such as pages, tables, and the like, that permits the system processes to reference objects on a shared access basis without obtaining a shared lock. A point of execution of the control program is monitored that is common to all processes in the system, which occurs regularly in the execution of each process and across which no references to any data object can be maintained by any process, except references using locks. A system reference point is established, which occurs after each process in the system has passed the monitored point of execution at least once since the last such system reference point. Operations requiring exclusive access, such as modification or destruction of the data object, are performed by, first, obtaining a conventional exclusive lock, then preventing any subsequent references to the data object, waiting until two of the system reference points have occurred, and, finally, performing the operation. Significant reductions in overhead can be achieved through the application of the invention.
