A method of replacing a current version of a program module with a replacement version of the module concurrently with the execution of the program on a computer system. For each entry point within the current version of said module to which the program may make address reference, a corresponding entry point within the replacement version of the module is determined. While execution of the program is suspended, each address reference in the program to an entry point within the current version of the module is replaced with an address reference to the corresponding entry point within the replacement version of the module. Execution of the program is resumed when each address reference to the current module has been replaced with one to the replacement module.

Rebuilding of storage structures within a shared storage processor of a computing environment. A rebuild of a storage structure, which is owned by an exploiter of the storage structure, is initiated. Thereafter, the storage structure is rebuilt via an operating system of the computing environment. The operating system is distinct from the exploiter owning the storage structure and lacks knowledge of the contents of the storage structure.
