Abstract
When using virtually stored data sets, such as virtual storage access method (VSAM) data sets, while the data set is open (referred to as an open time) static data set characteristics and/or job parameters have been defined for the VSAM data set. In one approach, a method for modifying a virtual storage access method (VSAM) data set includes opening a VSAM data set; and modifying a VSAM control block structure for the VSAM data set.
Claims13
A method for modifying a virtual storage access method (VSAM) data set, the method comprising:
- opening, using a processor, a VSAM data set;
- providing, using the processor, a VSAM dynamic address space associated with the VSAM data set;
- and
- modifying, using the processor, a VSAM control block structure for the VSAM data set using the VSAM dynamic address space while the VSAM data set is open during an open time in which static data set characteristics and/or job parameters have been defined for the VSAM data set,
- wherein the modifying the VSAM control block structure further comprises:
- interacting with the VSAM data set within the VSAM dynamic address space using a VSAM console interface and/or a VSAM programming interface;
- and
- building a service request block based on the VSAM dynamic address space,
- wherein the service request block modifies the VSAM control block structure within the VSAM dynamic address space.
