Unix Work |
|
Lists information about Unix work (work that generated a Unix Process Section in the SMF type 30 record). Information is taken from the SMF type 30 subtype 4 step or sub-step end records.
A type 30 record can include multiple Unix Process Sections for different processes. When this occurs there will be a multiple lines for a single job step, however only one entry will include job related information. Other entries only include information from the Unix Process Section.
Columns
Column |
Description |
Job |
Job name (SMF30JBN) |
Job Number |
The job identifier JOBnnnnn, STCnnnnn, TSUnnnnn etc. (SMF30JNM) |
Step |
Step number (SMF30STN) |
Step Name |
Step name (SMF30STM) |
Sub Step |
Sub-step number (SMF30SSN) |
Program |
The program name (SMF30EXN if available or SMF30PGM) |
Sysplex |
The Sysplex of the system that wrote the record (SMF30SYP) |
System |
The system that wrote the record |
Started |
The time the initiator selected the job (SMF30STD + SMF30SIT) |
Ended |
The time the job ended (SMF30DTE + SMF30TME from the subtype 5 record.) |
Elapsed |
Job elapsed time (end time - initiator select time) |
Process |
Process ID (SMF30OPI) |
Parent |
Parent process ID (SMF30OPP) |
Session |
Session ID (SMF30OSI) |
Process Group |
Process group (SMF30OPG) |
Descendants |
The number of descendants of this job entry. Descendants are entries for unix work that created separate SMF type 30 records (and usually ran in a separate address space) but was created by this job. |
Derived CPU |
CPU time calculated from the TCB and SRB CPU service values. This provides a more accurate value than the CPU time fields from the SMF 30 record, which are rounded to 1/100th of a second. The value includes Normalized zAAP and zIIP time which means that the value will exceed the total of actual CP + zAAP + zIIP time if the zAAP/zIIP is faster than the regular CP. |
EXCP Count |
I/O blocks transferred. (SMF30TEP or SMF30TEX) |
Connect Time |
I/O device connect time (SMF30TCN) |
Service |
Total Service Units (SMF30SRV) |
CPU |
CPU Service Units (SMF30CSU) |
SRB |
SRB Service Units (SMF30SRB) |
I/O |
I/O Service Units (SMF30IO) |
MSO |
Main Storage Occupancy Service Units (SMF30MSO) |
CC |
The step condition code (SMF30SCC) |
Service Class |
Service class name. (SMF30SCN) |
Report Class |
Report class name. (SMF30RCN) |
User ID |
The user id of the job. (SMF30RUD) |
UID |
Numeric unix UID (SMF30OUI) |
Group |
Numeric unix group ID (SMF30OUG) |
Unix Req. |
Number of unix services requested. z/OS will only collect data for this field when SYSCALL_COUNTS is set to YES (SMF30OSC) |
Unix CPU |
Accumulated CPU time for Unix services. z/OS will only collect data for this field when SYSCALL_COUNTS is set to YES (SMF30OST) |
Dir Reads |
Number of unix directory reads (SMF30ODR) |
File Reads |
Number of unix file reads (SMF30OFR) |
File Writes |
Number of unix file writes (SMF30OFW) |
Pipe/Sock Reads |
Number of pipe and AF_UNIX socket reads (SMF30OPR) |
Pipe/Sock Writes |
Number of pipe and AF_UNIX socket writes (SMF30OPW) |
Log. Path Lookups |
Number of logical pathname lookup calls (SMF30OLL) |
Phys. Path Lookups |
Number of physical pathname lookup calls (SMF30OLP) |
Log. Path Generation |
Number of logical pathname generation calls (SMF30OGL) |
Phys.Path Generation |
Number of physical pathname generation calls (SMF30OGP) |
