iSeries: an industry phenomenon
Optimised, integrated business computing for mid-enterprises
Enduring and unique software-based, hardware-independent architecture
avoids all costly technology transitions
Easy to manage, secure, highly reliable
Successful in business solutions driven mid market
Far lowest total cost of ownership amongst midrange systems

Product of General Systems Division, formed as result of anti-trust legislation.
Low -end batch system replacement for unit-record equipment. Used RPG
programming language. Disk and terminals soon added. 28-instruction CPU.
Over 25,000 sold.
System/3 follow -on.
System/32 follow -on. Ran SSP OS.
System/34 follow -on. Ran SSP OS.
Pioneering design, revolutionary architecture system, continued in AS/400
and iSeries to date, provides complete insulation for user applications against
technology change. Also, first system line to include in-built relational
database system. Ran CPF OS.
Repackaged and improved S/38, hugely successful in medium business
markets, using S/38 architecture. By mid-late 1990s, became open, ebusiness capable server. 200,000th AS/400 sold by 1992. OS/400 OS. From
1995 based on RISC chip (Pow erPC).
Repackaged and re-branded AS/400, under eServer strategic initiative.
Radically reshaped and extended, repackaged and re-priced iSeries,
repositioned as "On Demand" e-business hub platform consolidating
Window s/Intel, Linux, AIX, Java and Domino (as w ell as traditional OS/400)
w orkloads. Over $500M IBM investment.
Technology convergence w ith pSeries, including AIX in a partition.

methods that may
be used on it.

No need even to recompile,
since the program object
encapsulates its own TIMI

automatically re-translated

Otherwise same as IXS
Linux on IXS/IXA
Linux on PowerPC (i.e. in an iSeries partition) is tried and tested, but
vendor support for PowerPC Linux can be a problem. Linux on IXS/IXA gets
round this.
Seen by some IBMers as a stepping stone to PowerPC Linux, rather than as
a solution in its own right.
PowerPC Linux is more flexible: Intel Linux requires IXS/IXA hardware, and
processor and memory allocation are not dynamic.
VMWare ESX is not yet supported.
Linux on IXS/IXA has been available only since the autumn of 2004, with
no production deployment in the UK as yet.
Logicalis view: great future, but not ready yet.

CL commands
Integrated Filing System
One integrated structure
QSYS.LIB = libraries, objects and members
QDLS = traditional 8.3 folder/document tree
QNTC = Windows Network client – sees contents of your
Windows servers
includes file system level view of IXS/IXA
QFILESVR.400 = Remote IFS – sees contents of other iSeries
systems
QOPT = your iSeries’ CD drive
QIBM/ProdData and QIBM/UserData used by many IBM products
including WebSphere
Qxxx used by other IBM products
Other root folders
use Unix naming conventions, e.g. case-sensitive
Can define shares using NetServer and map them as network
drives from Windows
Jobs
All work progresses through the machine as a series of jobs. Jobs can have
various sources. The most important types of job are:
Interactive Jobs
An interactive job is one which starts when a user signs onto a display
station (i.e. a terminal emulation session). It is ended when the user signs
off; if he signs on again, another interactive job is initiated.
Server Jobs
A server job runs continuously on the iSeries waiting for requests from
clients (typically PCs).
Examples of server jobs are: FTP server; database server (used by ODBC
applications).
Typically, server jobs are listening on TCP/IP ports.
Server jobs vary in the way in which they are started.
Batch Jobs
A batch job carries out processing that requires no input from a client or
display station (for example, the generation of a report by an application).
A batch job is normally placed on a job queue via the SBMJOB command,
which has many parameters, of which the following are the most
important:
CMD - the CL command to be executed
JOB - the job name to be used for the batch job
JOBD - the job description to be used for this job
The job description specifies the job queue on which the job is to be placed,
together with a lot of detailed information about the job - the default
output queue for its spooled output, for example.
Print Writers (Spool Jobs)
These connect physical printers to output queues, and print spooled output
as it arrives.
Job tuning depends on job type. IBM ships sensible
defaults for traditional workloads.

Operator
Programmer
User
*SECADM *SAVSYS *JOBCTL *IOSYSCFG *SPLCTL *AUDIT: required in
addition to relevant resource access
*ALLOBJ gives *ALL access to all objects
Simplify your infrastructure: single level signon
What Every Enterprise Wants
Protect access to enterprise resources at lowest possible cost
What Every User Wants
Highest possible convenience and productivity
Not to have to remember or change passwords
SSO Definition
What we mean by SSO
The ability of an end user to sign in to the enterprise network and run
multi-tier applications without being prompted again for
authentication data, and without requiring the end user to have the
same user ID and/or password on every system.
What we don’t mean by SSO
Same user id everywhere
Same password everywhere
Centralized storing/caching of passwords
LDAP authentication
Kerberos and Enterprise Identity Mapping
Kerberos involves the acceptance of a single authentication by ‘Kerberised’
applications, avoiding the need for passwords
EIM links user ids for different servers, at individual or group level
Traffic cop
EIM can be used without Kerberos; Kerberos can be used without EIM
