II. MXG Technical Notes


1. Counting tape mounts.

Tape mount counts from the MXGTMNT monitor can be compared with the

tape mount counts (TAPNMNTS+TAPSMNTS) in the step records, and there

can be differences, mostly due to the difference in time-frame of

the mount records (when they occur) and the step records (when the

step ended):

- MXG will count high for Started Tasks that never end (e.g.DFHSM),

or for any job whose step record had not yet been written in the

SMF time-frame you examined.

- MXG will count low for steps that ended in the SMF time-frame, but

whose mounts occurred before the start of that SMF file.

- MXG counts physical mount events, but the type 30 counts completed

mounts, so when your tapeape intentionally mounts the wrong VOLSER

five times

if they can't find the right tape, they mount any tape, knowing

MVS label-check will prevent it from being used, but any mount

terminates the outstanding mount message so the MVS console guy

can't see how long the real mount has been waiting!

the MXG count is five mounts, the step record count is one.

- MXG misses some VTS scratch mounts, when using the default two

second sampling in MXGTMNT, because scratch mounts to VTS can be

fast. In one day MXG missed 200 VTS scratch mounts out of 2000

total VTS mounts with the two second sampling, but MXGTMNT saw

all of the VTS scratch mounts with one-half second sampling.


Recommendations:
If you want to compare totals, use the TYPE30_V or PDB.SMFINTRV data

from type 30 interval records instead of TYPE30_4 or PDB.STEPS data

to minimize (but not eliminate) time-frame error, since the interval

records will count the mounts for those long-running jobs and STCs.


If you do have Virtual Tape Devices, you could change the interval

constant in member ASMTAPES (INTERVAL DC F'200' to DC F'050') to

change the MXG default of 2.00 seconds to 0.50 seconds, and then

re-assemble to change the MXGTMNT program to sample at half-second

intervals. While 2 seconds is still the MXG default, half-second

was tested and briefly suggested as an alternative, as the CPU cost

was still small:

At half-second sampling, it took less than 3 CPU seconds per

15 minute interval to scan 100 tape devices, and another 1 CPU

second for every 100 tape mounts, or a few minutes per day with

2000 mounts.
However, even with .5 second interval, the mount monitor missed some

fast VTS mounts, which caused me to create the completely new logic

in the ASUMTAPE program, which creates the new PDB.ASUMTAPE dataset

(that should be used in place of PDB.TYPETMNT in tape mount

analysis). The new logic is driven by the type 21 dismount record,

so even if MXGTMNT missed the fast mount, PDB.ASUMTAPE has the tape

event, albeit with the tape mount duration missing (so you know it

was less than 2 secs!), so the original 2 second default was kept.


If you decide to change the sample interval, you can compare the

number of observations in PDB.ASUMTAPE that have missing TAPMNTTM,

to see how many more of the fast-scratch-VTS-mounts you actually

capture at 1/2 second instead of the MXG default of 2 seconds.


III. MVS Technical Notes.
1. APAR OW35684 confirms that the BLKSIZE in the DD segments of type 30

records is correct for tape but incorrect for a DASD dataset that is

being opened for output DISP=NEW when DADSM allocate did not

determine a system determined blocksize (SDB) even though BLKSIZE=0

was specified on the DD statement. DADSM SDB processing was not

done because DSORG and/or LRECL were not also specified. The APAR

is closed "FIN" - Fixed in Next DF/SMS Release in 18-24 months.
2. APAR OW31700 RMF OS/390 type 74 subtype 5 describes "short records"

created when there are more than 153 devices on a cache controller

(because 153 segments fills the 32756-byte limit of SMF data). They

have no impact on MXG, as MXG reads each record and outputs from

each device data section (but IBM had to add counters so RMF

could reassemble the large event from these 32K "small" records).

There may be an error, as I have seen type 74 subtype 5 records with

only the Product and Control section, with no status nor data and

with R745CCNT, record sequence, of 2. Site is talking to IBM.
3. SMF type 42 APARS:

APARs OW29633 corrects timestamps in TYPE42DS (type 42 subtype 6)

SMF records that caused SMF42PTS to be much earlier than the job's

READTIME. Reported in OW10694 (closed RET) and OW25624 (closed PER)

the actual error was a failure to freemain between jobs, so you

would have someone else's READTIME in your record. This error was

not fixed to correct SMF, but because someone's system stayed up

long enough that the memory leak causes a storage shortage ABEND!


APAR OW32248 discusses type 42 VSAM/RLS counter errors, affecting

SMF41IAY/IAZ/IBA/IBB/ICY/ICZ/IDA/IDB/IBG/IDG fields.


APAR OW35762 corrects count of SEQ blocks read and written for PS

datasets on non-SMS managed volumes.


4. APAR OW35952 corrects large value for IOUNITS in type 30 records;

the problem primarily affected DB2 address spaces with very large

(but legitimate) I/O counts that caused an overflow internally in

IBM code. The APAR text cites negative values in SMF30IO (IOUNITS),

but as MXG uses PIB instead of IB, very, very large values (so they

are noticed!) are created rather than small negative values.


5. APAR PQ18797 for MQ Series Release 1.3.0, PTF UQ23424 corrects zero

values for 'QMSTxxxx' variables in dataset MQMMSGDM from type 115

SMF record subtype 2.
IV. DB2 Technical Notes.
1. Boole and Babbage's MainView for DB2 product's THRDHIST VSAM file is

used for online access and its keyed record format is not public, so

MXG cannot support that file. But Boole recommends you create DB2

SMF records (their DB2 batch reports use the 100/101/102 records) so

THRDHIST was never intended to be useful for accounting or trending.
2. MXG Newsletter 34 reported that after installing APAR PN55122 and

migrating to CICS 5.1, that LU6.2 terminal's QWHCTOKN no longer had

the UOWID token in their DB2ACCT record (as a result, MXG's ASUMUOW

could not match DB2ACCT to CICSTRAN by Unit-of-Work ID). IBM has

now released APAR PQ15565 (and PTF UQ18583) to correct their error.
3. APARs PQ10864/PQ06968/PQ10864 discuss excessive numbers of DB2 type

101 SMF records that are created with CPU parallelism; if your DB2

application is running with more than 1 degree of CPU parallelism,

the child tasks will create SMF 101 accounting records every time

they are spawned (i.e., every SQL execution). In cases where an

application loops thru static SQL frequently or for transaction type

queries the volume can be a very serious problem. Use the DSNZPARM

macro DSN6SYSP PTASKROL parameter for parallel task accounting

control. APAR PQ06968 has been created to allow RLF to disable

modes of parallelism during static BIND; by using RLFFUNC=4 during

BIND, you can force problem applications back to IOP parallelism

(versus CPU parallelism). APAR PQ28414 provides a new ability to

limit the degree of query parallelism, and provides a maximum degree

parameter, PARAMDEG, and adds the field to the install process in

Version 6. This note updated with IBM input 19Dec1999.
V. IMS Technical Notes.

VI. SAS Technical Notes.


1. MXG 16.05 QA stream has executed using the SAS Version 7 Beta, under

OS/390, Windows 95/98 and Windows NT. Minor changes were needed in

MXG code, mostly to circumvent Beta things that SAS will have fixed

by the Production release this fall. A complete list will be in a

future MXG Technical Note when Version 7 is available.

Initial performance measurements of the MXG QA stream show no change

in the runtime between Version 6.12 TS045 and Version 7 Beta, so

it looks like lots of new features at no cost, for a change!


SAS Version 7 datasets cannot be read by SAS Version 6; the format

of SAS data libraries on all platforms was changed incompatibly.

Fortunately, MXG will not exploit on any SAS Version 7 features in

the near future, and there are no compelling reasons to migrate to

SAS Version 7 (run times and resources were about the same), but

when you do migrate to SAS V7, you will either have to drop it in

all at once, or at least you will need to install from the back end:

convert your report programs first and then convert the programs

that build the datasets that the reports use.
2. RETAIN statement only retains variables in assignment statements.

You cannot use a RETAIN statement with SET A B logic to retain the

value of variable A from dataset A into processing of observations

from dataset B. While the A variable will exist in the OUT dataset

its value will be missing:
DATA A; A=1;

DATA B; DO B=1 TO 5; OUTPUT B; END;

DATA OUT; SET A B;

RETAIN A;


To retain the value of variable A, you must assign it to a new name

(AA) while reading an observation from dataset A, retain that AA

name, and then when reading an observation from dataset B, assign AA

back to its original name A (and then DROP variable AA from OUT):


DATA OUT; SET A (IN=INA) B (IN=INB);

RETAIN AA; DROP AA;

IF INA THEN AA=A;

IF INB THEN DO; A=AA; OUTPUT; END;


Fortunately, variable A's attributes (LABEL, FORMAT, etc) are indeed

propagated into variable A in the OUT dataset.


3. SAS 6.09 TS455 and TS460 on MVS may encounter SAS "VM1319" or "NO

MKLEs" ABENDs, due to a memory overlay introduced by TS455. SAS ZAP

Z609E449 exists and is flagged as REQUIRED, but is not a true fix.

That ZAP forces SAS options MVARSIZE=0 and MSYMSIZE=0, which causes

%MACRO variables and symbol tables to be written/read to/from disk

instead of from memory. By reducing memory for macros, the overlay

may be avoided, but depending on how %macros are used, that ZAP

could impact runtime performance. The text of ZAP Z609E449 suggests

that increasing MEMSIZE may circumvent the error, since the overlay

is less likely with more addressability, so if you encounter the

error, first increase MEMSIZE by 8MB (and remember to increase your

REGION size), and then if that doesn't work, then either install the

ZAP, or install its effect by setting MVARSIZE=0 and MSYMSIZE=0

yourself.


4. SAS 6.09 TS455/TS460 do not free memory for user formats, which can

cause an out of memory error if there are repeated references to a

user format, e.g.,a DO Loop around PUT(variable,format) statement

where the format is NOT one supplied with SAS (MGxxxxx formats or

your own build with PROC FORMAT are "user formats").

SAS ZAP Z609F331 will correct this memory "leak".


VII. CICS Technical Notes.
1. There are two CICS summary programs in MXG:

ASUMCICS summarizes the detail CICSTRAN.CICSTRAN transactions, so

variable NUMTRANS counts the number of transactions.

ASUMCICX summarizes the already-summarized ASUMUOW unit-of-work

dataset, so NUMTRANS counts the number of unit's-of-work,

and variable MROTRANS counts the number of CICSTRAN

transactions that were executed by that unit-of-work.
2. APAR PQ13647 corrects invalid Y2K date in IBM type 110 subtype 2

TS Server records written by CICS TS 1.1 and 1.2. The dates will

contain 1AYY instead of 20YY without this fix.

VIII. Windows NT Technical Notes.


There are no Windows NT Technical Notes in this Newsletter.
IX. Incompatibilities and Installation of MXG 16.16.
1. Incompatibilities introduced in MXG 16.16 (since MXG 15.15):
a- IMACs that were changed (if they exist in your USERID.SOURCLIB, you

must refit your tailoring, starting with the new IMAC member):


IMACPDB - new PDB.STEPS/PDB.JOBS CONDCODE. Change 16.106
b- Other incompatibility changes:
All MGBYTES formatted variables are now length 8, instead of 4.

If you use PROC APPEND without FORCE, SAS will ERROR when you try

to combine new and old datasets with dissimilar length variables.
c- These products were incompatibly changed by their vendor, and they

require MXG Version 16.01 as indicated:


MXG Y2K support for AS/400 MXG 16.01 Change 16.035

CA-1/TMS TYPETMS5 with Magstar drives MXG 16.02 Change 16.088

LANDMARK CICS V2 recs convert to V8.1 MXG 16.01 Change 16.049

LANDMARK DB2 V 3.1 MXG 16.02 Change 16.097

MQ Series V1 R2 SMF 115 MQMLOG dataset MXG 16.02 Change 16.099

NETVIEW NPM (Year 2000 dates) MXG 16.01 Change 16.003

NTSMF EXCHANGE 5.5 MXG 16.01 Change 16.024


2. Installation and re-installation procedures are described in detail

in member INSTALL (which also lists common Error/Warning messages a

new user might encounter), and sample JCL is in member JCLINSTL.

X. Online Documentation of MXG Software.


MXG Documentation is now described in member DOCUMENT.

XI. Changes Log


==========================Changes Log=================================
You MUST read each Change description to determine if a Change will

impact your site. All changes have been made in this MXG Library.


Member CHANGES of the MXG SOURCLIB will always be more accurate than

the printed changes in a Newsletter, because the software is normally

created after the newsletter is sent to the printer! Member CHANGES

on the www.MXG.com homepage are the most timely, as they are updated

(sometimes) between MXG versions.
Member CHANGES always identifies the actual version and release of

MXG Software that is contained in that library.


The actual code implementation of some changes in MXG SOURCLIB may be

different than described in the change text (which might have printed

only the critical part of the correction that can be made by paper).
Scan each source member named in any impacting change for any comments

at the beginning of the member for additional documentation, since the

documentation of new datasets, variables, validation status, and notes,

are often found in comments in the source members.
