Abstract: Systems, methods, and other embodiments associated with continuous capture of replayable workload for a database are described. In one embodiment, a method includes capturing workload units being executed on a production database and storing the captured workload units in a circular workload buffer. The circular workload buffer is configured to write newest captured workload units over oldest workload units in the workload buffer when the workload buffer becomes full. The method includes, in response to detecting an event, exporting contents of the workload buffer to offline memory. The exporting includes at least one I/O operation. In one embodiment, an advisor feature guides set up of the continuous capture feature by providing historical workload data and making recommendations regarding an amount of memory that should be allocated to the workload buffer.

Abstract: A method and system for facilitating user interaction with a shell. In one embodiment, the method and system include receiving command input in a command line, wherein the command input comprises a partial command argument, wherein the partial command argument is followed by one of a space character and a tab; completing a command argument in the command line based on the command input; validating a command argument and values associated with the command argument if the partial command argument is followed by the space; and displaying context sensitive help based on the command input if the partial command argument is followed by the tab, wherein the context sensitive help comprises a syntax tree for the command argument.
