Abstract
A coupling facility is coupled to one or more other coupling facilities via one or more peer links. The coupling of the facilities enables various functions to be supported, including the duplexing of structures of the coupling facilities. Duplexing is performed on a structure basis, and thus, a coupling facility may include duplexed structures, as well as non-duplexed or simplexed structures.
Claims31
A method of halting execution of duplexed commands executing within a computing environment, said method comprising:
- detecting a resource condition by one instance of a duplexed command, said duplexed command comprising said one instance and another instance;
- and
- halting execution of at least the another instance of the duplexed command, in response to the detecting.
A system of halting execution of duplexed commands executing within a computing environment, said system comprising:
- means for detecting a resource condition by one instance of a duplexed command, said duplexed command comprising said one instance and another instance;
- and
- means for halting execution of at least the another instance of the duplexed command, in response to the detecting.
A system of halting execution of duplexed commands executing within a computing environment, said system comprising:
- a resource condition detected by one instance of a duplexed command, said duplexed command comprising said one instance and another instance;
- and
- a coupling facility to facilitate halting execution of at least the another instance of the duplexed command, in response to the detecting.
At least one program storage device readable by a machine tangibly embodying at least one program of instructions executable by the machine to perform a method of halting execution of duplexed commands executing within a computing environment, said method comprising:
- detecting a resource condition by one instance of a duplexed command, said duplexed command comprising said one instance and another instance;
- and
- halting execution of at least the another instance of the duplexed command, in response to the detecting.
