Msys for
Setup
The problem: CSA Shortage!
. Product 'A' requires 500MB for modules in LPA
- Program
objects can only be loaded dynamically into LPA
. Storage is taken from ECSA
. CSA specification is in IEASYS...
- Which can only be activated via IPL.
. Even more paging space might be required...
§ And the solution: C(pre-analysis à this is good stuff) J
. Plug-in would
. Check
whether paging space is already sufficient...
. Or
recommend to increase it.
. Increment
CSA specification by required value (if agreed by user)
. Add
SETPROG LPA command to COMMNDxx to load modules
. Based on
specification by user and whether sufficient free ECSA available
- either
suspend customization until next IPL...
- Or
activate changes dynamically
. Resume
further customization.
Regression Errors
Scenario: Multiple products customizations:
. Product A's customization adds to PROGxx APF: Lib1,
Lib2
. Product B's customization adds to PROGxx APF: Lib2,
Lib3
. Eventually product B gets removed
B removal –
results in Lib2 + Lib3 being removed from parmlib
(unless great
notes made - results in only Lib1 being authorized)
And the solution:
. Resolvers handle value conflicts context aware.
. History manager keeps old values for UNDO
processing.
. Manual changes recognized and accepted as
"manual overrides"
. These are generic msys framework functions which are
independent of parmlib

z/OS New Features
Managed System
Infrastructure for Operations
msys for
Operations
Automation to a new level
è NetView
for OS/390 à
è System Automation for OS/390 (SA OS/390).
SA OS/390 part of msys for
Operations runs on top of the NetView part.
NetView
- referred to as NVSS (NetView
System Services) supplies the infrastructure with basic services such as the
command interface, triggering of automated recovery, logging.
The SA OS/390
referred to as Sysplex Functions provides
-
the sysplex specific recovery functions
-
commands.
Licensing of msys for operations
It will be msys for Operations contains a subset of the functions
offered by the licensed products. You can migrate to the licensed products from
msys for Operations. The relation between the licensed products is similar to
that of the two parts of msys for Operations.
A licensed NetView is a prerequisite for the automation functions
of the licensed SA OS/390. Note that the origin of msys for Operations from two
licensed products is still visible in its panels and help texts.
Therefore, you may encounter ’NetView’ or ’SA OS/390’ where you
would expect ’msys for Operations’.
Examples of Recovery Automation
Managing the system logger
msys
for Operations provides the following recovery actions for these problems:
The primary and alternate LOGR CDS are automatically resized in
case of a directory shortage
The operator is notified when the share options for log stream
data sets are not defined correctly
The share options are checked on a daily basis. If incorrect share
options are detected, msys for Operations notifies the operator.
Resolving a system log failure
When the system log is inactive, msys for Operations tries to
start it by issuing the WRITELOG START command. In addition, it tries to make
it the hardcopy log.
The SYSLOG message automation has been enhanced by a recovery
function . Msys for
operations issues recovery action commands based on messages
Resolves
WTO(R) buffer shortages
Handles Long-Running Enqueues (ENQs)
Recovers Auxiliary Storage Shortage
Recording IPL Information -enables you to identify
parameters that were changed, for example, since the last IPL.
Specify Dump Options, and provides an easy-to-use
interface
64 Bit –VS- 31 Bit Addressing
Real benefit
è more real memory on a single CEC
dynamic address translation into real memory
Support for more LPARS or Linux Images
Didn’t Really need 64 bit Virtual yet!!!
This was the main reason for new Version
è requires new machine to deploy 64 bit addressing
Very few parts of operating system are using it
New Macros for above the Bar.
Z/OS is runs in Trimodal mode
è
support 24 bit, 32 bit and 64 bit commands
è
no more Estore
Future z/OS will be forced to use 64 bits machines
è not yet however
è z/OS 1.5 will run in 31 bit mode and support older machines
Other reasons for moving to new Zseries architecture
And
z/OS Operating System
Latter
QDIO and OAS Express GigaEther Express Card
Supported on Zseries
(not on Multiprise 3000)
10 meg / 100 meg / 1 gigabit / second data transfer
on
low cost card
TCP/IP stack offload -
lower 2 layers of the TCP/IP stack
--> cpu reduction
Supports multiple LPARS with one card
Concept of VIPA – hardware alternate path for backup incase of
failure of one
QDIO
Quick Direct I/O
Improved I/O with less resources of SAP + CPU processor
Faster I/O delivery
Automatic Configuration
Self Configuration of the OAT from IODF
Enterprise Extender
APPC + SNA Traffic thru IP network
Extending HPR
--> bulk data transfer using APPC encryption, data integrity
and data recover and high performance routing
Policy Agent
Shape Traffic as it moves thru the IP network
Integrated Services
è guaranteed bandwidth with
RSVP protocol
Differentiated Service
è delivery of packet based on Quality of Service setting in IP
header
z/OS operating System V1.4 – most advanced
OSA Gigaether Express card supporting Policy Agent
4 outbound queues
è packet queued based on priority shaped by service level agreements
and policy agent
Traffic Classification + Denial of Service Attacks
è can restrict open connections to a port (application)
è contain Denial of Service targeted at a specific application will
not bring down whole system or use up the max sockets set for the TCPIP stack
Need to Implement Policy Agent To Get use of Traffic
Classification
New SNMP Agents
Within z/OS
Including
TCP/IP address space to reset profile parameters
(no more OBEYFILE to change TCP/IP)
Gather Information On OSA Giga-ether Express Card
Policy Agent Information
Remote Ping using SNMP Agents
Resolver Config
New API with Centralized configuration File that selects the
proper Data dataset
è relating 4th layer application to a TCP/IP stack properly
Security for the z/OS in the Network
Very Exciting Stuff with potential for large Dollar Savings
Passive FTP client on z/OS
è Allowing FTP client usage thru the firewall from batch job
initiated on z/OS
SSL FTP Server/Client on z/OS tapping into Crypto Engines
Or
Kerberos Based FTP Server/Client
è move Data thru an encrypted pipeline over internet
è no password in the clear while signing onto FTP
TN3270E Transport Layer
Security (newer SSL) support
è encryption for privacy
è digital certificate authentication
è hash total for data integrity
Sign on thru internet with security
Without need for VPN
Proper Client Required

è backup and recovery
è improved Security
More Functionality in Open World
Configuration
Monitoring
Recovery
Applying Maintenance
More Software Products Offerings at Better Price then Competition
Integrated and delivered with
z/OS
è targeting small and medium business
Lower costing Options to encourage move with Incentives to move
More shaping and offloading

LDAP servers (not on z/OS)
+
SNMP Managers (not on z/OS)
Key Dates
OS/390 V2.10 service thru Sept 2004
Order z/OS V1.4 only until V1.5 made available
Q1 of 2004
è recommendation order V1.4 now
è start migration now
è free up time to take advantage and learn about all new network
features and how they may be deployed
Migration Considerations
Time is Running Out
To Place Order for Software
z/OS --> Q1/2004 will
arrive quickly
Support for OS/390 V2R10 will drop in less then 20 Months
“Time is Running OUT”
Consider New Z800 Processor
è dollar savings with ZECL Pricing
è about 30 to 35% on BASE z/OS software
(will help pay the cost of the hardware)
$$$$$$
Consider - z/OS.e Operating System and pricing where appropriate
Dual Processor Z800
– one half of Box runs Open World Applications
-
operating system hardware costs at
5% of standard z/OS
$$$$$$
Strategy
Do it Earlier then latter
Both Zseries Processor + z/OS Operating System
To
Free uptime to take advantage of new functions
that are supported in the new
Operating System
Msys for Setup --> time and $dollars$
Msys for Operations --> availability and $dollars$
New OSA Express Gigaether --> CPU savings + improved Bandwidth
Utilization + $dollars saving
Improved FTP with SSL/TLS
TN3270E
To
save cost of 3rd Party Products for Data Movement
$dollars$
