Elapsed time until timeout, data sharing
In a data sharing environment, because the deadlock detection process sends inter-system XCF messages, a given transaction typically waits somewhat longer before timing out than in a non-data-sharing environment.
How much longer a transaction waits depends on where in the global deadlock
detection cycle that the timeout period actually expired. However, the length
of time a process waits until timing out generally falls within the following
range:
MIN GLOBAL TIMEOUT = timeout period + DEADLOCK TIME value
MAX GLOBAL TIMEOUT = timeout period + 4 * DEADLOCK TIME value
AVERAGE GLOBAL TIMEOUT = timeout period + 2 * DEADLOCK TIME valueAgain, the maximum or average values might be larger.
