Everything about Global Resource Serialization

Component within the IBM z/OS operating system

Global Resource Serialization (GRS) is the component within the IBM z/OS operating system responsible for enabling fair access to serially reusable computing resources, such as datasets and tape drives or virtual resources, such as lists, queues, and control blocks. Programs can request exclusive access to a resource, usually requested when a program needs to update the resource or shared access, usually requested when a program only needs to query the state of the resource. GRS manages all requests in FIFO order. Wikipedia →
