A new FACILITY class profile (BPX.JOBNAME), used by the security product, provides additional control over who can specify JOBNAME on exec() or spawn(). Superusers or non-superusers who have access to the new BPX.JOBNAME facility class profile can change the JOBNAME.
OW34166 R7: UW54257
R6: UW54256
Servers that generate a large number of asynchronous I/O requests require a unique completion event to identify which I/O has completed. A 4-byte identifier (SIGVAL) can be set at async I/O start time so that when it is delivered to the application at async I/O completion time, it will identify which async I/O event has completed.
