WebSphere on z/OS is basically a set of MVS address spaces (Started Tasks)●Two Configuration Options:

●Base (stand-alone) AppServer●Network Deployment (ND) Controller Regions are started manually,

with an MVS start command, or using theIntegrated Solutions Console (ISC)

ControllerRegion

Control RegionAdjunct (CRA)

JVM

MEs MEs

WLMJCL

WLM starts servantsbased on workload seen

Parameters provide control overthis:

Minimum number of regions

Maximum number of regions

Each Server has several Started tasks:–Controller Region (CR) - protocol entry point: HTTP, HTTPS, IIOP or JMS

–Servant Regions (SR) - this is where the application components run (One or more)

–Control Region Adjunct (CRA) - if SI Buses with Messaging Engines are defined.

Servers can be replicated for workload balancing and high availability

WLM starts CRAif MEs defined

You'll Need to Do Some Planning

There's no avoiding it ... these things require a lot of names, values, portsand such.

Deployment Manager Definitions

WebSphere Application Server home directory:

/wasv8config/b8cell/b8nodea/AppServer

Cell name (short)......: B8CELL

Cell name (long).......: b8cell

Node name (short)......: B8NODEA

Node name (long).......: b8nodea

Server name (short)....: B8SR01A

Server name (long).....: b8sr01a

Cluster transition name: B8SR01

All components have two names

Defined using the ISPF dialogs

Long Namedescriptive name

used as directory names

used in Admin Console

Short Nameused as jobname for controllers

used in symbolic links

limited to 7 characters

Naming Scheme: cc|type|n|s

cc = Cell ID

type= sr01 (server #01)

demn (daemon)

dmgr (Deployment mgr)

agnt (Node Agent)

n = System ID (SYSA)

s = Servant or Adjunct

HFS Config root: OMVS.B8CELL.B8NODEA.CONFIG.HFSmounted at /wasv8config/b8cell/b8nodea

Start Command to Start WebSphere Application Server:

s b8acra,jobname=b8sr01a,

env=b8cell.b8nodea.b8sr01a

Reviewing HFS Directories, Roots & Homes

All directory names are user-defined...here are examples of our servers:

10/01/12 WAS V8 for z/OS Introduction, Copyright IBM Corp, 2012 5

The Profile Management Configuration Tool (zPMT)

Is a workstation graphical tool that captures key names, values and input fromyou and consistently imbeds those values in customized batch jobs.

Spreadsheet …

Hmmm, I’ll supply thefollowing values …

CustomizedBatch JCL jobs

These get uploaded to z/OSwhere they’re submitted, one

after another, to create theconfiguration runtime.

Uploading and running thejobs is the easy part.

The real challenge is coming up with all the names and values and portsthe PMT is going to ask for.

Without a plan for those names you’ll very quickly get confused.


Techdoc PRS4686: WAS V8 Planning Spreadsheet

An Excel spreadsheet that makes planning values and using the PMT mucheasier … it helps enforce a disciplined “top down” design:

Provide key variables inthe “Variables” sheet

Copy the generated variablesfrom the appropriate

worksheet and paste intoNotepad to create a file

Then point to the file in the“Response File” field of thewindow where you gave the

definition a name

Then just tab through the PMTwindows and generate the jobs

Creating the target Servers

For WAS V8, you must use the Profile Management Tool (zPMT)

– part of WebSphere Customization Toolbox (WCT)● Select Version 8,● Create Management, Managed (Custom) node

Monitoring WAS Address Spaces (Started Tasks):Use the DA (display active) command to get a good view of your server address spaces.●Use SDSF commands to 'set display on/off' and 'set action on/off'●Use the 'PREfix' or Filters to limit the rows (Jobnames) displayed.●Use the 'ARRange' command or pull-down to put interesting columns on the first panel.●Sort on JobName (instead of JobID or CPU%) to keep the rows from jumping around.

Key Points:

• Each team has their ownz/OS image

• You all use “wg31” as yourIP host, but it resolves to thespecific guest machine bythe workstation “hosts” file.

• We can re-clone your guestmachine … be careful but ifyou break something we canfix it

• Lots of virtualization goingon … good environment, butwe may see slowdowns.Please understand we’re in atest environment here
