Abstract: Embodiments are directed to a computer-implemented method for determining whether a program has been modified. The method can include determining that a first instance of the program is loaded in main memory. The method can further include determining a starting memory location of the first instance of the program. A second instance of the program is loaded into main memory. The second instance of the program is loaded such that memory references in the second instance of the program are resolved as if the second instance were loaded at the starting memory location of the first instance of the program. The first instance of the program is compared with the second instance of the program.

Abstract: A computer program product is provided for data currency improvement in a system having data sites running first and second applications within a common operating system hosted on a real or virtualized server and includes a computer readable storage medium having sequences of program instructions. The sequences of program instructions are readable and executable by a processing circuit to cause the processing circuit to establish first and second sites as active standby and active query sites, respectively, direct first and second transactions of the first application to the first site and to at least the second site, respectively, monitor replication delays from times at which data updates occur at the first site to times at which the data updates are replicated at least at the second site and set a delay for responding to the second transactions of the first application in accordance with the monitoring independent of a setting of any delay for responding to second application requests.
