108 Geac System21 commerce.connect: Implementation on the iSeries Server
5.1 Hardware
When you tune your configuration and system for performance, always start with the
hardware requirements for the configuration. For applications that use Enterprise JavaBeans
(EJBs), as both call.connect and vendor.connect do, you must be running one of the following
models with the corresponding feature code:
Model 170 feature 2385
Model 720 feature 2062
Model 270 feature 2252
Model 820 feature 2396
For all models, we recommend that you meet the minimum memory requirement of 1 GB.
To check the processor model and feature and the memory of your iSeries, use the following
command:
WRKHDWRSC *PRC
Then the Work with Processor Resources display (Figure 5-1) appears. In this example, the
model is shown against the resource CEC01. The feature is against MP01. You may need to
add multiple memory cards. If necessary, page down to see the complete list. The system
shown is a Model 170, with feature 2385 and 2 GB of memory. This satisfies the processor
requirements and more than satisfies the memory requirements.
Figure 5-1 Work with Processor Resources display
You can also check the model by using the Display System Value (DSPSYSVAL QMODEL)
command and check the processor feature by using the DSPSYSVAL QPRCFEAT command.
To check the memory, use the Work with System Status (WRKSYSSTS) command, but be
sure to add the memory pools.
These requirements are simple, although they give no indication about how older models may
perform. In addition, they do not provide any information about how the level of usage affects
the requirements.
iSeries performance is usually measured by an IBM benchmark called
Commercial
Processing Workload
(CPW). It is interesting to look at the CPW of the systems mentioned
earlier in this section:
Model 170 feature 2385 Processor CPW 460 Interactive CPW 50
Model 720 feature 2062 Processor CPW 420 Interactive CPW 35
