Hello;
Are there discussion groups similar to IBM-MAIN that are devoted to
Mainframe automation tools?

Environment: ZOS 1.12
The question:
What does HSM look at to evaluate the DATASETSIZE value?
We have coded the following in our startup parms for hsm (AN EXAMPLE)
ADDVOL ABC123 UNIT(3390) MIGRATION(ML1 NODRAIN NOOVERFLOW) THRESHOLD(80)
ADDVOL OVR123 UNIT(3390) MIGRATION(ML1

ML2 is relying on tape drive hardware compress and shows the full size
of the data set.
Thank You Mike for your response. It clarifies what I am seeing.

Problem Statement: We are attempting to estimate the number of compressed ML1
and ML2 data sets that will fit on EAV volumes.
For ML1 data sets, field UMDSIZE from IDCAMS DCOLLECT layout appears to be
reporting with reasonable numbers.
For ML2 the number does not seem close at all.

You had made mention of some tips and reference material.
One RedBook publication that gives a fairly good overview of VSAM is
Vsam Demystified.
Also, if you look at the publications
DFSMS Using Data Sets Document Number SC26-7410-10
This will help in understanding the structure of a VSAM
Another method will require some parsing of an IDCAMS DCOLLECT report output,
but, you can gather
data by Storage Group using it and tabulate utilization figures. You would
probably have to schedule a batch job via your job scheduler for some interval
value or whatever.
Thanks to all that responded to my inquiry. I will try some of the methods
suggested.

Hello;
I wish to detect when a BSAM read or QSAM GET crosses a concatenation
boundary.
I am guessing I need to code an OPEN and EOV DCB exit to get control. The
input data sets can reside on DASD or TAPE, but,
the environment does not mix unlike devices...all one way or the other.
Thank you Don and Kirk for responding.
I will check your recommendations out.
Sincerely Yours,

Hello;
I was curious what the 16 bytes in front of the JFCB is. I extract the 3
byte ADDRESS of the JFCB
from the TIOT, and, then need to step past a 16 byte area in front of the
actual JFCB. What is contained in the 16 byte area?
I have tried to make some sense of it.

I don't know of a tool that will actually pinpoint where a loop might exist,
but,
Omegamon, TMON-MVS, Mainview, as well as Strobe will give you an idea where the

You can then dump the ASID via a console dump, or, identify the csect where

I have seen some shareware code that uses SUBSYS calls to SMS to obtain such

in the SSSA prior to subsys call, but, I did not find any

Ralph Kaden has given you a slip trap to use which will pretty much get
you where you want to get to rather quickly
in identifying who is producing the record. It will require knowledge on how

I assume you are using file 171 from the cbt tape.
All the source is distributed in IEBUPDTE format. Member DITTOMAC contains the
macros.
Sample IEBUPDTE deck
// JOB
//JS01X01 EXEC PGM=IEBUPDTE,PARM=NEW
//SYSPRINT DD SYSOUT=*
//SYSUT2DD DSN=Receiving.pds,DISP=SHR
//SYSIN DD
Some additional notes:
If you want to manually look at the SVCTABLE, do the following:
Bring up IPCS with a SOURCE setting as ACTIVE.
Make sure you issue an IP DROPD to drop any previous analysis from a browse
ACTIVE storage session.
Go into browse...Option 1
