Deploying IBM Workplace Services Express on the IBM eServer iSeries Server

254 Deploying IBM Workplace Services Express on the IBM Eserver iSeries Server

9.1 iSeries architecture

The iSeries architecture implements many different functions in subsystems. Subsystems can

be thought of as isolated areas in the operating system memory that allow functions to run,

segmented from other workloads.

There are a number of components that comprise a Workplace Services Express server. This

includes the IBM HTTP Server that services HTTP traffic to and from the Workplace Services

Express server. The jobs that comprise the IBM HTTP Server associated with a Workplace

Services Express server are shown in Table 9-1. These server jobs run under the subsystem

QHTTPSVR. The IBM HTTP Server jobs have a run priority of 25. We discuss the effect of

run priorities in 9.3.3, “Run priority tuning” on page 261.

Table 9-1 IBM HTTP Server jobs

By default, the name of the HTTP job is the same name as the Workplace Services Express

server instance name.

Table 9-2 lists the three server jobs that are associated with each Workplace Services

Express server. These jobs run in the QEJBAS5 subsystem by default. You can optionally

change these jobs to run in a separate subsystem. To use specially created CL commands to

change the Workplace Services Express jobs so they run in a separate subsystem, see 9.3.4,

“Changing the subsystem Workplace Services Express jobs run in” on page 263.

The Workplace Services Express server jobs have a run priority of 20. This is important to

note if you have any 5250-based interactive workloads running on the same iSeries server or

in the same logical partition (LPAR).

The two Lightweight Directory Access Protocol (LDAP) server choices that run on the iSeries

are the IBM Directory Server and Lotus Domino. The IBM Directory Server runs under the

QSYSWRK subsystem and is comprised of the QDIRSRV job shown in Table 9-3. The run

priority of the IBM Directory Server is 50.

SERVER1 20 Used during the initial configuration process of a Workplace

Services Express server. It also provides administration services

for the Workplace Services Express server through the

WebSphere Application Server Administrative Console. During

normal server operation, this server might be ended.

WEBSPHERE_ 20 Responsible for responding to all Workplace Services Express

user requests.
