SMF Type 30 Record

This table shows the record layout for type 30 SMF records
(Common Address Space Work - z/OS 2.4).

List of other SMF record layouts available.
List of sample SMF reports.

Purpose: The type 30 SMF record provides accounting information. It consolidates data that is found in record types 4, 5, 20, 34, 35, and 40 (which simplifies accounting by installation-written post processing routines), and it provides additional information. Use record type 30, because the record types that it replaces are generally not being updated with new measurement data.

SMF writes record type 30 when:

A work unit (such as a TSO/E session, APPC/MVS transaction program, OMVS forked or spawned address space, started task, or batch job) starts. This subtype 1 record identifies the work unit but contains no resource data.
An SMF interval ends, if you requested interval accounting. If this is the first interval since the work unit started, then this subtype 2 record contains the total resources used from the start of the work unit until the end of the current interval. With interval synchronization, this span of time is normally shorter than the length of the SMF global recording interval. For global interval recording without interval synchronization, this span of time is the same as the length of the SMF global recording interval. For other intervals, this subtype 2 record contains the total resources used from the end of the previous interval until the end of the current interval. For system address spaces that do not go through full function start, SMF generates a subtype 6 record that contains the total resources used since the start of the address space. Note that the data in the subtype 6 record is cumulative, unlike the subtype 2 record.
A work unit (such as a TSO/E session, APPC/MVS transaction program, OMVS forked or spawned address space, started task, or batch job) completes. If you requested interval accounting, SMF generates a subtype 3 record that contains the total resources used from the end of the previous recording interval until the end of the work unit. This span of time is normally shorter than the length of the specified recording interval. For a job step, SMF generates a subtype 4 record that contains the total resources used from the time when the job step started until the time when the job step completed. If you requested interval recording, then this subtype 4 record generally contains the accumulated totals of the data in the interval subtype 2 and subtype 3 records that were generated for the step. For a job, SMF generates a subtype 5 record that contains the total resources used from the time when the job started until the time when the job completed. This subtype 5 record generally contains the accumulated totals of the data in the step total subtype 4 records that were generated for the job.

The type 30 record contains operation information such as the job and step start and end times, step CPU time, step termination status, number of records in DD DATA and DD * data sets processed by the step and job, device allocation start time, problem program start time, and storage protect key. The record contains the number of page-ins, page-outs, swap-ins, and swap-outs for both virtual input output (VIO) and non-VIO data sets. The record contains information on the number of hiperspace page moves and the movement of pages between expanded storage and central storage. This data can be used in resource planning. Information is added to account for time spent in hiperspace processing on a step or interval basis. The record contains an entry for each data set defined by a DD statement or dynamic allocation. Each entry lists the device class, unit type, device number, the execute channel program (EXCP) count, and device connect time for the data set. The usage data section contains information that can be used to attribute usage of a product to the address space.

The type 30 record can be used with subtype selectivity function.The subtypes are:

1 Job start or start of other work unit
2 Activity since previous interval ended
3 Activity for the last interval before step termination
4 Step total
5 Job termination or termination of other work unit
6 System address space, which did not go through full function start. When you select subtype 6 for record type 30, the following fields may contain zeros or blank: SMF30PGM, SMF30STM, SMF30PSN, SMF30CL8, SMF30UIF, SMF30USR, SMF30JNM.

Information in specific fields may differ for different subtypes. For example, the record identifies the job (and job step) by the:

Job log identification (job name, time and date that the reader recognized the job card for this job).
Step name
Number of the step within the job
User identification
Program name
Performance group number or service class name
JES job number.

If accounting numbers (which can be alphameric) are specified in the JOB or EXEC statements, they are included. For subtype 1 and subtype 5, the accounting numbers are taken from the JOB statement. For all other subtypes, the accounting numbers are taken from the EXEC statement.

Because some of the information necessary to complete a field is not always available when a type 30 record is written, some fields might be empty. For example, the SMF30AST, SMF30PPS, SMF30SIT, and SMF30STD fields are not filled in for a subtype 1 record.

Because system address spaces do not use full function start, the subtype 6 record is incomplete; that is, only certain fields in each section are valid. All unused fields are set to zero or blank.

The subtype 6 records are written only at the expiration of an interval; the values are cumulative and indicate data collected since the initialization of the address space. If a system address space later goes through full function start, data is not reported for the period between the expiration of the previous interval and the time that the address space goes through full function start. The subtype 6 record contains data for the APPC/MVS Cumulative Resource section, but data in the APPC/MVS Resource section is not reported in subtype 6.

The length of record type 30 is variable. The maximum length of the type 30 record is 32,756 bytes. If the volume of data in the type 30 record is such that the length would exceed the maximum length, one or more additional type 30 records are produced. The additional records contain only the header/self-defining, subsystem, identification, and one or more sections that can repeat. An example of a section that can repeat is the execute channel program (EXCP) section.

Notes:

1. Data sets are recorded in the order of the DD statements; they are not identified by name. However, the data definition name (ddname) is included in the record. (An installation-written IEFUJV exit routine can record this order as each statement is validated). For concatenated DD statements, the ddname is the same on each entry, respectively.
2. CPU time is not expected to be constant between different runs of the same job step.
3. If the SMFPRMxx parameter DDCONS(YES) is specified, then duplicate execute channel program (EXCP) entries are consolidated. If DDCONS(NO) is specified, then duplicate EXCP entries are not consolidated. SMFPRMxx parameters are described in z/OS MVS Initialization and Tuning Reference.
4. If a section is not included in the record, the "number of" entry is zero. For example, subtype 1 does not have a completion segment, and SMF30TON is set to zero to indicate this.
5. If the IEFUSI exit changes the size of the private area, a flag is set in SMF30SFL in the paging and storage section.
6. Specifying the DETAIL parameter of the SMFPRMxx parmlib member for STC includes all EXCP sections in subtypes 4 and 5 for the step or job.
7. Specifying the NODETAIL parameter excludes EXCP sections from subtypes 4 and 5 for STC class subsystem jobs, but not for batch or TSO/E subsystems. NODETAIL is enforced for the master address space.
For OMVS, the OMVS address space is considered a started task (STC), so NODETAIL is honored for processes running in the OMVS address space. However, processes that run under a BPXAS initiator are considered batch work, so NODETAIL has no effect.
8. Considerations for jobs that are evicted via the $EJxx,STEP (or equivalent) command:
- SMF30CNR (bit 14 of SMF30STI) is set in the subtype 4 record of the last step that executed prior to the eviction.
- A subtype 5 record is not generated for a job that is evicted until the job resumes and completes execution.
- Except for the following fields, subtype 5 fields that contain aggregated data will not include data from all steps in a job that resumes and completes execution following an eviction. In this case, subtype 5 fields will contain data aggregated from the steps that ran after the job resumes execution up until the job completes execution. In the subtype 5 record of an evicted job, these fields will contain data aggregated from all of the steps in the job: SMF30CPT SMF30CPS SMF30_TIME_ON_IFA SMF30_TIME_IFA_ON_CP SMF30_TIME_ON_SUP SMF30_TIME_SUP_ON_CP
9. While a job is executing, SMF writes the type 30, subtype 1, 4, and 5 records associated with each job step to the job's EVENTLOG data set. You can use the Job Step panel of the Spool Display and Search Facility (SDSF) to view these records. To control access to this information, the EVENTLOG is protected with two SAF resources in the JESSPOOL class: nodeid.userid.jobname.jobid.EVENTLOG.SMFSTEP and nodeid.userid.jobname.jobid.EVENTLOG.STEPDATA.

When you use the SMF30CPT field in the Accounting section:

Note that a workload may generate different values for SMF30CPT, if some eligible work for the System z Application Assist Processor (zAAP) or IBM System z9 Integrated Information Processor and IBM System z10 Integrated Information Processor (zIIP) running on a standard processor. If a repeatable value is more desirable than the possible performance benefits of letting zAAP or zIIP eligible work run on both specialty CPs and standard processors, specify IFAHONORPRIORITY=NO or IIPHONORPRIORITY=NO in the IEAOPTxx parmlib member.

Interval records may show this number to be hundredth (1/100) of a second less than other related SMF30 fields (such as SMF30_TIME_IFA_ON_CP). This difference is due to rounding differentials while calculating delta values, and will not occur for step end or job end.

If SMF30CPT is zero, and you would like to understand how much CPU time was used by the address space or you require more precise values in general, you can calculate the CPU and SRB time in microseconds (1 / (10^(-6))) using the following formulas:

CPU time:
(SMF30CSU * 10) / SMF30CPC * SMF30SUS / 16 = CPU time in microseconds
SRB time:
(SMF30SRB * 10) / SMF30SRC * SMF30SUS / 16 = SRB time in microseconds

The CPU and SRB times computed from service units include zAAP time and zIIP time in addition to CP time. The time derived from CPU service is comparable to the sum of fields SMF30CPT, SMF30_TIME_ON_IFA and SMF30_TIME_ON_zIIP for work with no enclave activity. If the zAAP or zIIP processors are faster than the CP, zAAP or zIIP time is normalized to the time expected on the slower CP before service units are computed. Therefore, the derived time contains normalized zAAP or zIIP time. Field SMF30ZNF contains the normalization factor used. Enclave time is summed with address space time in SMF30CPT. The computation above includes dependent enclave time but does not include independent enclave time. To compute independent enclave time, substitute SMF30ESU for SMF30CPC in the equation above.

If you use derived processor times, you determine

derived CP time = CPT / (CPT + IFAT + zIIPT) * derived CPU time
derived zIIP time = zIIPT / (CPT + IFAT + zIIPT) * derived CPU time
derived zAAP time = IFAT / (CPT + IFAT + zIIPT) * derived CPU time

where:

CPT = SMF30CPT
IFAT = SMF30_TIME_ON_IFA
zIIPT = SMF30_TIME_ON_ZIIP

assuming the denominator is not zero.

This section is located on the record using the following triplet fields, which are located in the "header/self-defining" section:

Offset SMF30UOF
Length SMF30ULN
Number SMF30UON - Reports the number of I/O activity sections on the current record. Because only one I/O activity section can appear on the record, this field is "1" (if the section exists) or "0" (if it doesn't).
(Offset from beginning of record: SMF30UOF)

Completion Section
This section contains the completion information for the step on the Step Termination record (Subtype-4) and for the job on the Job Termination record (Subtype-5). This section does not appear on the Job Initialization (Subtype-1) or Interval (Subtype-2 and 3) records.
Note: The SMF30STI field also contains some general record indicator flags which are not necessarily completion in nature. The system may fail a step or job even if the return code is zero. This could happen, for example, as a result of specifying CATLG_ERR FAILJOB(YES) and incurring that type of post execution error. (A return code is generated by the application program and is never changed by the operating system.) A user can deduce that a step failed due to a "post execution error" if bit SMF30SYE in the two-byte SMF30STI field in the SMF30 subtype 4 record is on.
Triplet Information:
This section is located on the record using the following triplet fields, which are located in the "header/self-defining" section:

Offset SMF30TOF
Length SMF30TLN
Number SMF30TON - Reports the number of completion sections on the current record. Because only one completion section can appear on the record, this field is "1" (if the section exists) or "0" (if it doesn't).
(Offset from beginning of record: SMF30TOF)

SMF30SCC

binary

Step completion code:
X'0ccc'	indicates system abnormal end of task (abend) in the job step where ccc is the system abend code. (See z/OS MVS System Codes.)
X'8ccc'	indicates user abend in the job step where ccc is the user abend code.
X'nnnn'	indicates normal completion where nnnn is the contents of the two low-order bytes in register 15 at termination.
X'0000'	indicates either:
	1. The job step was flushed (not processed) because of an error during allocation or in a preceding job step, or
	2. The job step terminated with an abend code ending in X'0D'. In this case, SMF30SCC contains the value from the low-order two bytes of the TCBCMPC field, which may contain zeros.
	3. Normal job step completion with a return code of 0. Use this field in conjunction with the job/step termination indicator field, SMF30STI.

Use this field in conjunction with the job/step termination indicator field, SMF30STI.

Job completion code:
X'0ccc'	indicates system ABEND in the last job step where ccc is the system abend code. (See z/OS MVS System Codes.)
X'8ccc'	indicates user abend in the job step where ccc is the user abend code.
X'nnnn'	indicates normal completion where nnnn is the contents of the two low-order bytes in register 15 at termination.
X'0000'	indicates either: (see note)
	1. The last job step was flushed (not processed) because of an error during allocation or in a preceding job step, or
	2. The job step terminated with an abend code ending in X'0D'. In this case, SMF30SCC contains the value from the low-order two bytes of the TCBCMPC field, which may contain zeros.
	3. Job completion with a return code of 0 in the final step of the job.

Use this field in conjunction with the job/step termination indicator field, SMF30STI.

Note: When a step in a multi-step job terminates abnormally, the subsequent steps, whether executed or flushed, do not propagate the step abend code for processing this record. The code appears in the step termination record (subtype 4). In this case, the field, SMF30SCC, can contain X'nnnn' or X'0000'. If an abend occurred in the job, the job termination indicator (bit 7 in the SMF30STI field).

0	Reserved
1	Canceled by exit IEFUJV
2	Canceled by exit IEFUJI
3	Canceled by exit IEFUSI
4	Canceled by exit IEFACTRT
5	Step is to be restarted
6	If zero, then normal completion. If 1, then abnormal end of task (abend). If step completion code equals 0322 or 0522, then IEFUTL caused the abend. If step completion code equals 0722, then IEFUSO caused the abend.
7	If zero, then normal completion. If 1, then step was flushed.
8	EXCP counts might be incorrect because the record did not include all the DD statements.
9	Previous interval record was not written because an error occurred. The cumulative count might be incorrect because the counters were cleared.
10	EXCP sections were not merged from the interval to the step record or from the step to the job record
11	Step completed with a "post execution" error. Post-execution errors include a failure that occurred because the ALLOCxx parmlib member specified CATLG_ERR FAILJOB(YES).
12	Step completed due to z/OS UNIX exec function request.
13	JOB abnormally ended because of COND= condition on the JOB card. This flag will be set on in the subtype 5 job termination record only.
14	Job was evicted via the ,STEP,HOLD or equivalent command. This bit is set for subtype 4 (step end) records only.
15	Reserved.

SMF30CPT

binary

All standard CPU step time in hundredths of a second. Includes enclave time, preemptable class SRB time, client SRB time. Also includes time consumed by IFA eligible work running on a standard processor. For time spent on an IFA, see SMF30_TIME_ON_IFA.

Because the times used the CPU and SRB time in microseconds (1/100 of a second using the following formulas:
CPU time: (SMF30CSU * 10) / SMF30CPC * SMF30SUS / 16 = CPU time in microseconds
SRB time: (SMF30SRB * 10) / SMF30SRC * SMF30SUS / 16 = SRB time in microseconds

Note that a workload may generate different values for SMF30CPT if some IFA eligible work runs on a standard processor. If a repeatable value is more desirable than the possible performance benefits of letting IFA eligible work run on both IFAs and standard processors, specify IFAHONORPRIORITY=NO in the IEAOPTxx parmlib member.

Interval records may show this number to be hundredth (1/100) of a second less than other related SMF30 fields (such as SMF30_TIME_IFA_ON_CP). This diffeence is due to rounding differentials while calculating delta values, and will not occur for step end and/or job end.

This value includes the value in field SMF30OST.

SMF30CPS

binary

Step CPU time under the service request block (SRB), in hundredths of a second.

You can calculate the SRB time in microseconds (1/100 of a second using the following formula:

Execute Channel Program (EXCP) Section
This section contains the I/O information for a specific DD Name/Device address pair for the address space. There can be multiple EXCP sections for a given address space.
With the SMFPRMxx parameter EMPTYEXCPSEC(NOSUPPRESS) specified, the system generates one EXCP section for each SMS candidate volume. The SMS candidate volume EXCP section contains only the DD name, SMF30DDN. All other fields in the EXCP section are zeros. This is the default behavior.
With SMFPRMxx parameter EMPTYEXCPSEC(SUPPRESS) specified, no empty EXCP sections are created for non-allocated candidate volume in the SMS storage group.
Triplet Information:
This section is located on the record using the following triplet fields, which are located in the "header/self-defining" section:

Offset SMF30EOF
Length SMF30ELN
Number SMF30EON - Reports the number of EXCP sections on the current record.

This section also has additional control fields in the "header/self-defining" section:

SMF30EOS reports the number of EXCP sections for the current period on Subsequent Type 30 records. These are known as the "chained" Type 30 records.
SMF30EOR also reports this same information but is only a 2 byte field which can overflow so SMF30EOS is the preferred field for processing this data.

Note: Virtual I/O devices are identified by the following:
Device Class - 0
Unit Type - 0
Device Number - X'7FFF'
It is important to understand the following:
- Allocation messages for VIO data sets will show VIO ALLOCATED TO ddname.
- SMF records will show VIO unit addresses as X'7FFF'.
- The actual in-storage UCB built for VIO will show address X'3FFF'.
For example, the messages:
IEF237I X'3FFF' ALLOCATED TO ddname
EF237I X'7FFF' ALLOCATED TO ddname
indicate that ddname is not allocated to a Virtual I/O device, but is instead allocated to a real device whose unit address is X'3FFF' or X'7FFF' respectively.
(Offset from beginning of record: SMF30EOF)

SMF30DEV

binary

Device class.

SMF30UTP

binary

SMF30DDN

EBCDIC

DD Name used to access the data set. Data sets are recorded in the order of the DD statements; they are not identified by dsname. (An installation-written IEFUJV exit routine can record this order as each statement is validated). For concatenated DD statements, the ddname is the same on each entry, respectively.

SMF30BLK

binary

Count of blocks issued for the device against the data set. This field has a maximum value of X'FFFFFFFF' = 4,294,967,295. If it exceeds that value it will wrap to zero and then continue to increase again for additional blocks transferred.

SMF30BSZ

binary

Largest blocksize of the data set

Bit	Meaning When Set
0	Indicated changed blocksize for the data set. Post processors should use this field to avoid the possibility of negative numbers.
0	1-15 Largest blocksize of the data set.

SMF30DCT

binary

Device connect time for this data set (in 128 micro-second units). For DIV object, device connect time is not collected by SMF; however, this field may not always be zero. For example, if a user is using a DIV data set and calls a VSAM utility to process it using the same DD statement, this will result in device connect time being charged by VSAM to the DIV object.

SMF30XBS

binary

Block size value.

Accounting Section
This section contains the user accounting information for the address space and the unit of work that is being reported on. The JOB level accounting information, taken from the ACCT parm of the JOB card is presented on the Job records for the address space (Subtype-1 and Subtype-5); while STEP level accounting information, taken from the ACCT parm of the EXEC card is presented on the Step records for the address space (Subtype-2, Subtype-3 and Subtype-4).
The format of the data in the section is continuous "internal text" which is:

Length: 1 Byte; "0" indicates no associated accounting field
Field Variable - length defined by previous "length" field

Triplet Information:
This section is located on the record using the following triplet fields, which are located in the "header/self-defining" section:

Offset SMF30AOF

Storage and Paging Section
This section contains the statistics on the use of different kinds of storage by the address space and the different kinds of paging activity for the address space.
Triplet Information:
This section is located on the record using the following triplet fields, which are located in the "header/self-defining" section:

Offset SMF30ROF
Length SMF30RLN
Number SMF30RON - Reports the number of storage and paging sections on the current record. Because only one storage and paging section can appear on the record, this field is "1" (if the section exists) or "0" (if it doesn't).
(Offset from beginning of record: SMF30ROF)

SMF30RSV

Reserved.

Note that SMF30RGN, formerly a two-byte field at this offset, has been increased to four bytes and moved to the end of the Storage and Paging Section.

Usage Data Section
This section contains the product ID information (specified on the REGISTER request of the IFAUSAGE macro) and the usage data that has been collected for the time period (interval, step, or job), for the product in the current address space only.
For registered products with a domain of TASK and a scope of ALL (example, IMS), there will be one usage section in the record for each unique product that is actively registered at the time the specified interval ended (as opposed to any part of the specified interval). In addition, there will be one section in the record for each unique product ID that has deregistered at least once during the specified interval.
Note: The data for deregistered products with a domain of TASK and a scope of FUNCTION is consolidated into one section in the record by unique product id. This is only performed at the specified interval level.
For all other registered products, there will be one section in the record for each unique product ID (owner, name, version, qualifier) that is actively registered for any part of that specified interval.

Spectrum SMF Writer - the 4GL SMF Report Writer.

Example -- Normalizing the EXCP Sections in an SMF Type 30 Record

This example shows how to split each "physical" type 30 SMF record into multiple "logical" records. Each logical record contains just a single EXCP section. Using this logically expanded input file, it is then easy to use the standard 4GL syntax to make useful reports from the array of EXCP data in each type 30 record. (That is because normalization puts a single EXCP section at the same location in each logical record.)

Since the main purpose here is just to illustrate how to normalize an input file, this example simply lists some fields from the EXCP sections of a few records. Specifically, we list the SMF30DEV (device class), SMF30DDN (DDNAME) and SMF30BLK (block count) fields from the EXCP section. The other report fields all come from the constant portion of the SMF 30 record.

By the way, there are many different kinds of variable sections in the SMF type 30 record (not just EXCP sections). For example, there are I/O activity sections, processor accounting sections, performance sections, storage sections and others. You can normalize any of these sections using this same technique with Spectrum Writer. You can even normalize more than one section of the record in the same run.
