Abstract:
1. A method for managing a buffer in a mainframe computer, said buffer comprising one or more individual buffers and accessible by an application executing under an application server, the application and the application server executing in a first address space of the mainframe computer and said buffer managed by a database adapter executing in a second address space of the mainframe computer, wherein said buffer is directly addressable by a central processing unit (CPU) of the mainframe computer, said method comprising: receiving by said database adapter executing in said second address space of said mainframe computer a first data request from said application executing in said first address space of said mainframe computer-comprising a buffer locator, wherein said buffer locator is in an empty state; allocating by said database adapter a first buffer in said first address space; storing by said database adapter an address of said first buffer in said buffer locator; copying by said database adapter said first data associated with said first data request received from a database subsystem to said first buffer; and transferring control to said application whereby said application utilizes said buffer locator to access said first buffer and process said first data contained therein.
