A computer-implemented method, a computer system, and a computer program product for data storage alteration monitoring is provided. The present invention may include, obtaining a page record, wherein the page record includes, for an event monitor having an associated target memory address to be monitored for changes, an entry identifying an associated page of a secondary data storage containing the associated target memory address. The present invention may also include, responsive to identifying a first event monitor having an associated first target memory address to be monitored for changes, analyzing the obtained page record to identify a first page containing the first target memory address. The present invention may further include, controlling enablement of the first event monitor based on whether the first page, identified in the analyzed page record, is loaded into a physical main memory of the computer system.

Storage alteration monitoring

A method, computer system, and computer program product for operating a computer system to carry out a data dump of a data image of memory contents. Computer operations are temporarily suspended to service the dump request in order to dump the volatile memory contents required for the data image and to generate a record of the non-volatile memory pages which need to be dumped. Computer operations are then resumed under supervision of a monitoring process which screens access requests to the non-volatile memory against the dump record. A request relating to a page contained in the dump record is acted upon by writing the contents of that page to the dump storage space, so the page contents is dumped before it is modified. The dump record in continually updated to keep track of what is still outstanding to complete the dump until such time as the dump is complete.

Virtual address space dump in a computer system

A method, apparatus, and computer product for avoiding redundant data transmissions during communication via multimedia mobile phones. In operation, a sending party inquires whether intended for transmission data already resides in a mobile phone of a receiving party Depending on a content of the response from the receiving party, the sending party transmits the data or a request for displaying the already available data.
