z/OS UNIX Process Section

Reports on the use of z/OS UNIX by z/OS UNIX processes.

Offsets Name Length Format Description
0 0 SMF30OPI 4 binary z/OS UNIX process ID.
4 4 SMF30OPG 4 binary z/OS UNIX process group ID.
8 8 SMF30OUI 4 binary z/OS UNIX process user ID.
12 C SMF30OUG 4 binary z/OS UNIX process user group ID.
16 10 SMF30OSI 4 binary z/OS UNIX process session ID.
20 14 SMF30OSC 4 binary Number of z/OS UNIX services requested by the process. When the z/OS UNIX parmlib option SYSCALL_COUNTS is set to NO, there is no collection of data for the count of syscalls. When gathering syscall counts for a job, do not switch between SYSCALL_COUNTS=YES and SYSCALL_COUNTS=NO because doing so can lead to inaccurate values in the SMF30OSC field.
24 18 SMF30OST 4 binary Total CPU time (in hundredths of a second) accumulated by z/OS UNIX services requested by the process. Note that the value in SMF30OST is already included in fields SMF30CPT or SMF30CPS. When the z/OS UNIX parmlib option SYSCALL_COUNTS is set to NO, there is no collection of data for CPU usage. When gathering CPU usage for a job, do not switch between SYSCALL_COUNTS=YES and SYSCALL_COUNTS=NO because doing so can lead to inaccurate values in the SMF30OST field.
28 1C SMF30ODR 4 binary Number of z/OS UNIX directory reads for the process.
32 20 SMF30OFR 4 binary Read I/O block count for z/OS UNIX regular files.
36 24 SMF30OFW 4 binary Write I/O block count for z/OS UNIX regular files.
40 28 SMF30OPR 4 binary Read I/O block count for z/OS UNIX pipes and AF_UNIX sockets.
44 2C SMF30OPW 4 binary Write I/O block count for z/OS UNIX pipes and AF_UNIX sockets.
48 30 SMF30OSR 4 binary Reserved.
52 34 SMF30OSW 4 binary Reserved.
56 38 SMF30OLL 4 binary Number of pathname lookup calls to the logical file system.
60 3C SMF30OLP 4 binary Number of pathname lookup calls to the physical file system.
64 40 SMF30OGL 4 binary Number of pathname generation calls to the logical file system.
68 44 SMF30OGP 4 binary Number of pathname generation calls to the physical file system to determine a pathname.
72 48 SMF30OPP 4 binary Parent process ID.
76 4C SMF30OKR 4 binary Reserved.
80 50 SMF30OKW 4 binary Reserved.
84 54 SMF30OMS 4 binary Reserved.
88 58 SMF30OMR 4 binary Reserved.
92 5C SMF30OSY 4 binary Number of times the sync() function was called.
