IBM Enterprise Workload Manager Release 1

Chapter 2. Installing and configuring EWLM 53

2.5.3 Domain manager on i5/OS

Installing the EWLM code when your domain manager runs on i5/OS cannot be done directly.

For this you need to use the iSeries™ Access family of products to administer and access

your iSeries server. In our ITSO environment we use IBM eServer iSeries Access for

Windows. This means, the installation of the Virtualization Engine base support and EWLM

code works as on Windows. However, you need to insert the CD labelled “VE Console &

Runtime for OS/400® (1 of 3)” into your Windows PC; this automatically launches the

installation wizard on the Windows PC. For the first screen you need to provide the i5/OS

server name and login information. The installation of WebSphere Application Server takes a

lot longer than on the other operating systems we discussed in this chapter. You may find that

it takes up to two hours.

Once the EWLM code and WebSphere Application Server are installed on the i5/OS we need

to log on to the system. We run the STRWLM CL command with the following options:

# STRWLM CFGID(ewlmadm) MODE(*DMNMGR) DMNMGRNAME("9.56.204.66") DOMAIN(itsoewlm)

DMNMGRPORT(9092)

All configuration scripts require the EWLM configuration ID as a parameter. This allows all

information associated with a specific instance of an EWLM component to be easily found.

The ID is created by running the STRWLM CL command, which creates a directory under

/qibm/userdata/wlm/servers/<configID>. It contains all EWLM-related information. In addition,

it is used to name the WAS instance and causes the WebSphere data to be placed in a

directory called /qibm/userdata/webas51/base/<configID>.

The WebSphere Application Server instance is created using the createCC command. For

this to run we issue the qsh command to be able to run shell commands. We run the

command sequence as shown:

# cd /qibm/proddata/wlm/bin

# createCC ewlmadm -adminUser qsecofr -adminPW 111111 -wasPorts 20000 -jp 9092

For the configID parameter we take ewlmadm. It uniquely identifies the domain manager server

job and must be the value you passed on the STRWLM CL command. The adminUser is used as

WebSphere administrator and must conform with the requirements WebSphere sets.

However, for i5/OS there are no special requirements for WebSphere Application Server. To

install and configure EWLM the system administrator needs to have *ALLOBJ, *SECADM,

*JOBCTL, and *IOSYSCFG special authority. In our test setup we used the administration

user qsecofr.

The next step is to map users to the specific EWLM roles. These users must be created first

on the operating system. We can then issue the changeCC command with the arguments

shown in Example 2-13. Run the startWAS command and open a browser to the EWLM

Control Center as described for our ITSO environment. You should be able to log on as one of

the users specified here.
