Welcome to the House of Chuckie!
Here you'll find:
Background
I joined IBM in 1982 as a CMS developer, working on:
- CMS 3: CMS 3380 support SPE
- CMS 4: GCS recovery machine and MACHEXITs
- CMS 5: CMS performance improvements
in the SVC handler, memory management, and virtual reader I/O
- CMS 6:
SFS GRANT and REVOKE AUTHORITY commands and their underlying CSL
routines, DMSGRANT and DMSREVOK.
In 1987, I moved into
System Evaluation, where I focused on customer-oriented testing of
VM. It is there that I developed my expertise
in VTAM, APPC, NCP, EP and TCP/IP.
In 2000 I left the test organization and formally moved into the
Development team where my primary area of responsibility was z/VM security.
However, I kept my hand in virtual networking and VM TCP/IP.
In the Fall of 2010, I left z/VM Development, joining IBM System z Lab Services as
a z/VM and Linux consultant. I now work directly with customers on a variety
of z/VM-related topics.
In addition to my technical responsibilities, I have taken on the role
of ombudsman. That is, I pay attention to what you, our clients, are saying
about z/VM. To that end, I monitor the public fora in which IBM, System z,
and z/VM are discussed. These include the
IBMVM, LINUX-390, IBMTCP-L, and IBM-MAIN mailing lists.
I regularly speak at the System z EXPO and Technical Conference in both the
United States and Europe, and am an IBM
representative to the Linux-VM program of
SHARE.
I was the z/VM rep to WAVV and a member of WAVV's Executive Council, but
now I just speak when I'm invited. :-)
In addition, I've given many presentations to
Bay Bunch, MVMUA, HillGang, NEUVM, and CAVMEN.
You can reach me at: Alan_Altmark at us.ibm.com (the @ sign was left out
to frustrate e-mail harvesters).
if you want to discuss any aspect of z/VM.
