second SMF record containing only the two remaining Cache

Data sections (one each for structure 13 and 14), but as

neither the Structure nor Request Data sections are in

that second record, it is IMPOSSIBLE for MXG to decode

the second broken record.


The record has SMF74RAN=1, indicating the "Reassembly

Area" exists, but that design (to reassemble multiple

"broken" records into a large record in the virtual

memory of the reading program) requires offsets from one

SMF record to be used to input fields in another SMF

record, and that algorithm fails unless all of the SMF

broken records are adjacent and found in the input SMF

file, which cannot be guaranteed (as, for example, when

the first broken record is the last record in today's SMF

file, or if the SMF data was presorted).


"Broken" records and reassembly areas are not new, but

IBM has previously never spanned logical data fields

between two physical records. Both the 74 subtype 1 and

subtype 2 records are "broken" when there are many

devices, but each "broken" record is self-contained and

can be decoded with no dependency on other records. The

required solution for the type 74 subtype 4 record is for

IBM to write self contained data records. The first

record should contain only as many Request Data sections

as will fit with their associated Cache Data sections.

Second and subsequent records must contain the Product,

Local Coupling Facility, and Structure data sections, and

then as many Request Data and their Cache Data sections

that will fit together.


To circumvent the error, an additional condition:

AND CDSILOC+SMF744CL LT LENGTH

was inserted in the existing IF statement

IF R744CDSI GT 0 AND R744CDNE GE 1 THEN DO;

before the THEN, so that the missing cache data sections

are skipped (causing missing values in TYPE74ST). Thus

far, only a few bad 74.4 records have been found per

day on this OS/390 R2.8 system.


While IBM's RMF Reporter does handle these broken records

if they are found in the same SMF input file (which RMF

has to first sort for the reassembly algorithm), if the

second record is not in today's data, the RMF Report just

skips that interval in its reports!
In conversation with RMF developers, they have now agreed

to revise their design so that when "broken records" must

be written, they will be self-contained and not dependent

on the contents of other records for decoding.


This investigation also uncovered an MXG oversight; only

the first cache data section was read for each structure,

but there are a few structures that have as many as 63

cache data sections, (but only two of those sections had

any non-zero counter values!). Now MXG sums all of the

cache data section counters for each structure.

Change 17.377 Change 17.290 changed SORT fields, but this JCL example

JCLIMSL6 was overlooked (LG and L5 were correct). It should be:

Jan 21, 2000 SORT FIELDS=(1,12,A,43,8,A,29,1,A),FORMAT=BI

as described in the text of that change.

Thanks to John Pierce, Liberty Mutual, USA.
Change 17.376 Variables POOLNPBY and POOLPGBY in NTINTRV dataset were

NTINTRV from the SERVER dataset instead of from the MEMORY data,

Jan 21, 2000 so their values were not correct in NTINTRV. Inserting

(DROP=POOLNPBY POOLPBY) after _LNTSERV in the MERGE

statement will correct this error.

Change 17.374 Windows 2000 NTSMF enhancements, etc.

EXNTSMTN -Objects 'Job Object' and 'Job Object Details' are still

EXNTTRMS flakey, sometimes containing NRNAMES and instance names

EXNTTRMV (1 in Job Object, 2 in Details), sometimes NRNAMES=0.

FORMATS While this is being resolved, MXG now protects both,

IMACNTSM (but if NRNAMES=0, then the names will be blank and the

VMACNTSM records of questionable utility!).

VMXGINIT -New variable FTPUPTME added to FTPSERV dataset from the

Jan 20, 2000 'FTP Service' object.

-Three new objects supported:

dddddd Dataset Object

NTSMTN SMTPNFS SMTP NFS Store Driver

NTTRMV TERMSERV Terminal Services

NTTRMS TERMSESS Terminal Services Sesion

-Sixty new variables added to SMTPSERV dataset from the

'SMTP Server' object are protected, but not input; I

ran out of time in building MXG 17.10, but call for

the update.

Jan 21, 2000: No update needed; MXG 17.10 did contain

all of the new variables, but I forgot to go back and

change this text.

Thanks to Jim Quigley, Con Edison, USA.


Change 17.373 TRNDRMFI has been updated to keep xxxxMEMR memory vars

TRNDRMFI as 8 bytes, like all other measures of memory, so that

Change 17.370 This test version of VMXGSUM enables a SAS VIEW in the

XMXGSUM first datastep to reduce time and resources (CPU, I/O,

Jan 19, 2000 and especially DASD space, since a VIEW is essentially a

pipe that avoids hardening a dataset. This version also

allows you to create the output dataset as a view with

OUTDATA=X/VIEW=X, syntax (but of course you must use that

dataset before you invoke VMXGSUM again). This member

will become VMXGSUM in the next version, but is placed

here for wider testing; copy this XMXGSUM into VMXGSUM

in your USERID.SOURCLIB to test it yourself.

Thanks to Chuck Hopf, MBNA, USA.
Change 17.369 CPU Activity Report can now utilize the INTERVAL and

ANALRMFR MYTIME parameters for summarization tailoring.

Jan 18, 2000
Change 17.368 Support for Beta91 Balancing Manager SMF Record creates

EXTYBE9A four new datasets from the many subtypes:

EXTYBE9B "dddddd" Dataset Label

EXTYBE9C TYBE9A BETA91A BETA91 HEX ST 10,14,28,48

EXTYBE9C TYBE9B BETA91B BETA91 HEX ST 22,24,36,42,44

FORMATS TYBE9C BETA91C BETA91 HEX ST 50

IMACBE91 TYBE9D BETA91C BETA91 HEX ST 60

TESTUSR1 The second variable data portion of the subtype 22-44

TYPEBE91 record is not documented, so those fields are not yet

TYPSBE91 decoded into dataset BETA91B.

VMACBE91 -Minor, but SMFCSTIM was shifted one byte to the left in

VMXGINIT the record ('45400000'x instead of '00454000'x for noon),

Jan 17, 2000 so there is an extra divide by 256 required.

Thanks to W. Waldeyer, BHF-Bank AG, GERMANY.


Change 17.367 NETSPY NSPYAPPL dataset had missing values for response

EXNSPYAP time and percentages when NETRSPN6 (computed number of

VMACNSPY LU6.2 responses) was zero. Logic was added to use the

Jan 15, 2000 TOTRSPN6 (total number of LU 6.2 responses) if NETRSPN6

is zero. Additionally, exit EXNSPYAP tested only TRANSNO

or OUTPUTNO, which suppressed output of any interval that

had LU6.2 traffic but no 3270 traffic. The test now also

tests TOTRSPN6 so that LU6.2-only intervals are output.

Thanks to Julian Smailes, Experian Limited (UK), ENGLAND.
Change 17.366 Deleted TMS volumes still in the TMC that had DENX=00x

VMACTMS5 printed DENSITY IS MISSING and a hex dump of the record

Jan 14, 2000 on the log, with no other impact. The existing test

ELSE IF DENX=0DEX THEN DEN=0; was expanded to read

ELSE IF (DENX=0DEX OR DEL='Y') THEN DEN=0; and that

block of code was relocated to after DEL='Y' is set.

Thanks to Warren Hayward, TJX, USA.
Change 17.365 The _Sdddddd and _Bdddddd macros (SORT and BY list) have

VMACTCP been updated so they can now be used. The _SUBTCP5 macro

Jan 13, 2000 was deleted, as it was never referenced; the statistics

record is recognized by length, not by subtype (which was

user-settable and thus not reliable!).

Thanks to Dr. Alexander Raeder, Karstadt AG, GERMANY.


Change 17.364 XCF Path Statistics report, updated to report all

ANALRMFR paths.

Change 17.363 Year 2000. Julian Date Values for these products have

VMACACF2 been protected to convert 01yyddd values to 20yyddd:

VMACCTLT TYPEACF2 - LIDADATE, LIDCDATE, LIDDXPDT, LIDIPDAT, prot.

VMACLMS TYPECTLT - CTLTDSN/CTLTVOL variables protected.

VMACPROS but there are EXPDT fields that are not

Jan 14, 2000 protected for invalid dates (like 99366).

TYPELMS - This code had not been updated in a long time.

EXPDT is now correct, but several datasets

were also corrected, and the code now runs

under ASCII as well as EBCDIC versions of SAS.

These changes support Sutmyn/VTS/LMS 3.4.

TYPEOMAU - OMJULDAT is protected, and OMDATIME corrected.

TYPEPROS - GWADATE protected. GWAEXPDT is character.

TYPEWSF2 - No julian date variable, listed in error.

Unfixed, awaiting raw data:

TYPEIAM: IAMCDATE=0852 decimal, 0354 hex, doc dddy!!!


Unvalidated, these products have unvalidated fields and

VMACTMO2 and lowatermark values in TMON for CICS/ESA 2.0 (TCE)

Jan 13, 2000 statistics interval records will be always zeroes after

applying SYSMOD TH01288 to TMON, but the HWM values in

the TI record will still be valid, as they are obtained

differently than the TCE records. The SYSMOD text has an

extensive discussion of why the TCE HWM/LWM values cannot

be calculated when the TCE interval is different than the

CICS statistics interval. These fields in these records

will be zero:

Change 17.361 Extension to Change 17.339 for EREP records. Now, all

VMACEREP EREP record types are tested and will be bypassed (and

Jan 12, 2000 and MXG WARNING message printed on the log) if any of the

invalid record bits are enabled; previously only the

record types that had experienced bad bits were

protected. IBM's EREP writes out truncated records when

it runs out of buffer space, and sometimes EREP doesn't

edit the record and only writes out what's in the buffer,

and sometimes EREP writes out incomplete records. Also,

MCH '13'x record conditionally inputs ERRORID by testing

length in LRBMLNH to avoid STOPOVER.

Change 17.360 The RMFINTRV/VMXGRMFI enhancements added in MXG 17.09

VMXGRMFI have been revised and corrected, so the errors and fixes

RMFINTRV apply only to the 17.09 code, but all of the new stuff

TRNDRMFN now works! Your existing IMACWORK member will continue

Jan 12, 2000 to work to define your workloads, if you do nothing, but

Jan 20, 2000 now you can EDIT member RMFINTRV (instead of IMACWORK) in

your USERID.SOURCLIB to create new workloads either in

addition to your IMACWORK workloads, or instead of, by

ignoring in IMACWORK completely. Member RMFINTRV invokes

%VMXGRMFI, so you EDIT RMFINTRV to change the arguments.


Remember, you NEVER change member VMXGRMFI; you only read

it for its documentation of the arguments in comments.

Then, in your RMFINTRV member, you invoke %VMXGRMFI with

your chosen workload definitions, parameters, etc.

Member RMFINTRV has documentation and examples in its

comments.


To match output to input sums exactly, all of the length

4 variables in RMFINTRV are now stored in 8 bytes. The

truncation when stored in four bytes is only in the 7th

significant digit, so using length 4 is not wrong, but

with a daily totaly of 1,000,000 seconds, that caused a

visually-obvious-even-if-not-significant difference of

0.1 of those million seconds lost between RMF & RMFINTRV.

Since I wasted a full day chasing down that difference, I

decided the small increase in DASD space would be worth

you never having to ask why there was any difference!


RMFINTRV now uses SAS VIEWS to pass data from one step to

another without using DASD space, but now, an ignorable

note "A stored DATA STEP view cannot run under a

different operating system" is printed on the SAS log.


Some additional documentation comments.
Specifying IMACWORK=NO may cause UNINITIALIZED VARIABLE

messages on the SAS log for the old variables that you

no longer want. Putting a comment block aroung the

label statement in your EXRMFINT member will eliminate

those messages, but they have no impact.
Any workload can be broken into periods, with a set of

variables for each period, including response time,

transaction count, and swap count as has always been

done for the TSO workload. You need to tell VMXGRMFI

how many periods to be mapped with the syntax:

WORKn=NNNN/LLLLLLLL/PGN/SRVCLASS/PERIODS

See PERIODS= in member VMXGRMFI.
If you specify to use Report Classes/Perfgrps, but you

also say to use your IMACWORK member, and that IMACWORK

member still contains the default to delete Report stuff

the IMACWORK will have deleted the Report stuff before

the new definitions are used. You will need to revise

your IMACWORK member to permit use of Report stuff.


Trending on the new RMFINTRV variables can now also be

done, with this new VMXGRMFI's TRENDIN=, TRENDOUT=,

TRENDBY=, and TRNDINTV= arguments, and by setting PDB=.

Member TRNDRMFN is an example of the new syntax that

will invoke VMXGRMFI to create TREND.TRNDRMFI with all

of the new workload variables.


These 17.09-only errors were corrected:
-The default IMACWORK=YES caused MXG error message that

RMFINTRV CPU TIMES DO NOT MATCH because OTHRCPU was

included twice in the creation of variable CPU72TM.

17.09 sites can remove the OTHRCPU from the end of:

,BATCPU,TSOCPU,CICSCPU,IMSCPU,OTHRCPU,

OTHRCPU is the fallthru workload for undefined PERFGRP or

SRVCLASS that were not mapped in your IMACWORK, so if all

work was mapped, then OTHRCPU will be zero and this error


does not occur.

-That error message does NOT set a return code nor stop

your BUILDPDB job (because once you see the error and

fix your workload definitions in your IMACWORK member

or in your RMFINTRV invocation of %VMXGRMFI, you can

simply re-run the RMFINTRV program to re-create the

PDB.RMFINTRV dataset, without re-reading SMF data.

-Detailed validation of 17.09 corrected values in a few

variables from TYPE71 and TYPE74 datasets.

-Using IMACWORK=NO and RPGNs did not use the RPGN data.

Thanks to Bruce Lietz, Cessna Aircraft, USA.

Thanks to Normand Poitras, ISM, CANADA.


Change 17.359 VMXGSUM fails if variable names are created in lower case

VMXGSUM and KEEPALL=NO default is used with SAS V7/V8, as that

Jan 12, 2000 space-saving option invokes logic to figure out what

variables need to be kept, and because the output dataset

created by PROC CONTENTS that contains the list of

variable names that exist has lower case values in

variable NAME, but the dataset created by parsing of the

arguments (like SUMBY=) that contains the list of

variables that are needed has upper case values in its

variable NAME, which then causes the MERGE matchup:

MERGE A (IN=INA) B (B=INB); BY NAME; IF INA AND INB;

to fail, as it sees those NAMEs as different values.


And since there is no SAS facility for case-insensitive

character tests nor case-insensitive MERGEing, three

UPCASE() functions were inserted in the three places

where variable NAME is read from the PROC CONTENTS output

dataset.
I discovered this one while creating CHANGE 17.358, and

accidentally used lower case in my test program, but it

was very nasty in impact and not obviously caused. There

was no error condition, but the output dataset had only

17 observations instead of 212; there were a few MISSING

VALUES messages on the log during MXGSUM1 creation. Only

when the SUMBY variables were printed was it found that

one of them did not exist in the output dataset, which

led to the discovery and fix.
Using argument KEEPALL=YES will circumvent this error,

because that bypasses the NAMEs matchup, but it can waste

//WORK space if there are many unused variables.
Ain't mixed case fun?????
Change 17.358 An additional sample NETSPY report that replicates the

ANALNSPY MICS SNTNSS report from MXG's NSPYLU dataset was added to

Jan 12, 2000 the examples in ANALNSPY. (However, the MICS report does

not correctly count input transactions; the MXG report

prints both the MICS number and the true number).

Thanks to Gene Rahe, Experian, USA.


Change 17.357 To modify BUILDPDB to copy CICS Statistics datasets to

EXPDBOUT your PDB, you should insert this code in EXPDBOUT:

Jan 12, 2000 _S110

Jan 20, 2000 MACRO _SCICEXC %

The BUILDPDB writes all CICS Statistics datasets to the

work file (to later create PDB.CICINTRV), but those 50+

individual CICxxxx datasets are not copied into the PDB

by default (they can be large; if you don't ask for them,


they won't waste any space in your PDB). That macro

invocation of _S110 sorts each TYPE110 dataset to the

PDB, and the two MACRO redefinitions to null out the

sorts of datasets CICSEXEC and CICSYSTM are needed

because BUILDPDB will try to sort them later in its own

logic, after the EXPDBOUT exit has been executed.


Note: if you don't want to create any observations from

the type 110 subtype 2 CICS statistics records, add this

statement: IF ID=110 AND SUBTYPE=2 THEN DELETE; in

your IMACFILE exit member.

Thanks to David Ehresman, University of Louisville, USA.
Change 17.356 Using Excluded CICS fields with CICS TS 1.3 failed,

IMACEXCL because the DO group IF MCTSSDCN LT 202 ... should have

Jan 11, 2000 been deleted when the TS 1.3 INPUT logic was copied into

member IMACEXCL. Delete that DO group.

Thanks to Tony P. Steward, Post Office, ENGLAND.
Change 17.355 Type 42 Subtype 7/8 NFS records caused INVALID NF-CL

VMAC42 SECTION TRIPLET error, but the message itself was in

Jan 11, 2000 error. The test OFFCL+LENGTH GT LENGTH should have been

OFFCL+LENGTH-1 GT LENGTH. The INPUT of SMF42CHL (twice)

was changed from &PIB.4. to &PIB.2. and SUBTYPE= was

added to those INVALID messages. Datasets TYPE42NF and

TYPE42NU were affected.

Thanks to Alan Deepe, Perot Systems Europe, ENGLAND.


Change 17.354 Summarized variable RESPSTD was always zero; the code

ASUMCICS SQRTARG=(SSQELAP/NUMTRANS)-(IRESPTM**2);

ASUMCICX must be changed to read:

Jan 11, 2000 SQRTARG=(SSQELAP/NUMTRANS)-((IRESPTM/NUMTRANS)**2);

Thanks to Normand Poitras, ISM, CANADA.
Change 17.353 Protection for the unwise. If you use the same name for

VMAC7072 a Service Class and for a Report Class, the MXG NODUP

WEEKBLD removal would not remove all duplicates. Adding variable

MONTHBLD RPRTCLAS at the end of MACRO _BTY72GO will not impact the

Jan 11, 2000 existing sorted datasets but will delete any duplicate

records in TYPE72GO.

Thanks to Chuck Hopf, MBNA, USA.
Change 17.352 Year 2000. Variable OUTDATE was still a 0cyyddd value,

VMACTMS5 having been overlooked by Change 16.330, but now it is

Jan 11, 2000 converted into a yyyyddd value.

Thanks to Freddie Arie, Texas Utilities, USA.


Change 17.351 Format MGSTCRS was corrected to 00/01 UN-/CONFIGURED.

FORMATS Labels for STC26MST/MET were changed to TAPECOPY vice

VMACSTC MIGRATE, for STC26VPO was changed to Position on the new

Jan 8, 2000 MVC, and for STC26MID was changed to VTV VOLSER.

Thanks to Herb Strazinski, US Bank, USA.
Change 17.350 SYNCSORT flag variables CONTIGn was wrong if SMFWKCID

VMACSYNC contained multiple bits, variable CACHFWn was created but

Jan 8, 2000 not kept, and two new flag variables were not decoded.

Now, CONTIGn and CACHFWn are kept and right, and two new

variables are decoded and kept:

DYNALOn = 'WORK n*DYNAMICALLY*ALLOCATED?'

UNOPENn = 'WORK n*UNOPENED*DISP=OLD?'

for n=1 to 32, for each possible Sort Work Area. Also,

the UCB address in variables UNIT1-UNIT32 is now the four

digit character address, so their stored length was


increased from $3 to $4.

Thanks to Steve Colio, CIGNA, USA.


Change 17.349 IBM Documentation of TELNET LOGF Date and Time Fields was

VMACTCP wrong, causing MXG variable TELLOGFT to be wrong.

Jan 7, 2000 Instead of being the time of logoff, the time field at

offset 82-85 is the elapsed duration of the session! And

the date field at 86-89 is redundant with the SMF date

field (and this is the date field that IBM's APAR PQ34359

plans to change from the non-standard yyyydddF format to

0cyydddF in spite of its uselessness!). Adding the

session duration and that date field created a value on

Jan 3, 2000, for a session that ended Jan 1, which made
