Cics reentrance
WebCICS allocates extents to the requesting DSA/EDSA/GDSA. If a request is greater than the initial extent size of 256KB/1MB/1GB, CICS will combine multiple extents creating a larger extent to satisfy the request. For example, a task requests 300KB below the line (greater than a 256KB extent), so CICS will find 2 contiguous UDSA 256KB WebAny subroutine used by the handler that could potentially have been executing when the interrupt was triggered should be reentrant. Similarly, code shared by two processors accessing shared data should be reentrant. Often, subroutines accessible via the operating system kernelare not reentrant.
