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) |
