This document discusses the use of the Host Configuration Utility which is part of IBM Rational Developer for System z Version 8.0.3. The Host Configuration Utility is an ISPF panel application that guides you through basic and common optional customization steps for Developer for System z. The application also allows you to execute Installation Verification Procedures (IVPs) and collect debug information. For complete details on the configuration of this product, refer to Rational® Developer for System z® Host Configuration Guide (SC23-7658).
For earlier releases, use the configuration information found in the Host Configuration Guide for those releases.
From here on, the following names are used in this manual:
This document is part of a set of documents that describe Developer for System z host configuration. Each of these documents has a specific target audience. You do not have to read all documents to complete the Developer for System z configuration.
The information in this document applies to all Rational Developer for System z Version 8.0.3 packages including IBM® Rational Developer for zEnterprise™.
This document is intended for system programmers who are going to configure Rational Developer for System z Version 8.0.3.
This document describes the different steps needed to do a setup using the Host Configuration Utility. Refer to Rational Developer for System z Host Configuration Guide (SC23-7658) for complete details on the configuration of this product and non-default settings.
To use this guide, you need to be familiar with ISPF. Some z/OS UNIX experience is useful for a better understanding of certain aspects, but it is not required.
The Rational Developer for System z Host Configuration Utility is a utility created to assist customers with Developer for System z host installation customization, installation verification and debug reporting. The Host Configuration Utility is referred to as the "utility" within this document.
The utility is designed to manage multiple configurations of a single Rational Developer for System z service level, hence providing configurations for test and production implementations of the product.
The utility is intended to ease the complexity of installation and customization of required tasks and selected common optional tasks. This is paired with a detailed logged customization workflow that can be interrupted and restarted at will.
Multiple users can use the same set of configuration files (but not simultaneously). This allows one person to create a configuration, and someone else with proper authority can execute specific steps of the configuration.
The utility consists of a series of partitioned data sets that can be divided into two groups, common product data sets and user-specific data sets created by the utility. There are also a few members added to the user's ISPF profile data set.
The product data sets listed in Table 1 contain REXX execs, ISPF panels, message files, and control files. These data sets should be available in read-only mode to all users of the utility.
Data set name | Description |
---|---|
FEK.SFEKEXEC | REXX execs to run the utility |
FEK.SFEKINPT | Control files |
FEK.SFEKMSGS | ISPF message files |
FEK.SFEKPANL | ISPF panels |
FEK.SFEKSKEL | Skeleton members tailored by the utility |
FEK.SFEKTABL | ISPF PF-key tables |
The number of user-specific data sets created by the utility varies, because it depends heavily on the type of actions done by the user, and the number of configurations that are created. Each configuration is identified by a 4-digit number (nnnn in Table 2). The data set names all start with a user-specified high-level qualifier, followed by a product-determined low-level qualifier (which can be one or two qualifiers long).
Data set name | Description |
---|---|
hlq.$R$D$Z | Temporary data set which is deleted during the termination procedure. |
hlq.RDZLOG | Contains a log file for each version of the commands/JCL create by the utility. The member name is RDZnnnn. |
hlq.RDZTABL | Contains the profile table. |
hlq.RDZnnnn.ASM | Contains sample assembler code for configuration nnnn. This data set matches the FEK.#CUST.ASM data set referenced in the Host Configuration Guide (SC23-7658). |
hlq.RDZnnnn.CMD | Contains generated command files for configuration nnnn. |
hlq.RDZnnnn.CNTL | Contains generated command files for configuration nnnn. This data set matches the FEK.#CUST.CNTL data set referenced in the Host Configuration Guide (SC23-7658). |
hlq.RDZnnnn.COBOL | Contains generated command files for configuration nnnn. This data set matches the FEK.#CUST.COBOL data set referenced in the Host Configuration Guide (SC23-7658). |
hlq.RDZnnnn.JCL | Contains generated command files for configuration nnnn. This data set matches the FEK.#CUST.JCL data set referenced in the Host Configuration Guide (SC23-7658). |
hlq.RDZnnnn.PARMLIB | Contains generated parmlib updates for configuration nnnn. This data set also matches the FEK.#CUST.PARMLIB data set referenced in the Host Configuration Guide (SC23-7658). |
hlq.RDZnnnn.PROCLIB | Contains generated proclib updates for configuration nnnn. This data set matches the FEK.#CUST.PROCLIB data set referenced in the Host Configuration Guide (SC23-7658). |
hlq.RDZnnnn.IVP | Contains generated IVP output for configuration nnnn. |
hlq.RDZnnnn.DEBUG | This is a sequential data set that will contain the debug report file when run for version nnnn. |
FEK* members with user-specific preferences are added to the user's ISPF profile data set (DD ISPPROF in TSO) during execution of the utility.
The system requirements match those of the Rational Developer for System z release it is part of, and are documented in Prerequisites Guide (SC23-7659), which is available in the Developer for System z online library at http://www.ibm.com/software/rational/products/developer/systemz/library/index.html.
The user ID running this utility must have (at least) the following attributes:
Figure 1 shows a schematic overview of the panel structure used by the utility. It also marks the flow you follow during the initial configuration of Developer for System z.
The utility is started by executing FEKINIT, which resides in SFEKEXEC, from within an ISPF environment. The following sample invocation command can be used from any ISPF panel command line:
TSO EXEC 'FEK.SFEKEXEC(FEKINIT)'
FEKINIT can accept optional positional parameters:
The user will be asked to confirm or change this value during startup.
Rational Developer for System z Vx.x utility initialization Driver level ddmmyyyy HLQ for install datasets = FEK A high level qualifier for user configuration datasets is required Enter the HLQ or press enter to default to FEK.#CUST HLQ for user datasets = FEK.#CUST |
The options panel specifies the names of input and output data sets and directories. MVS™ based output always goes to one of the user-specific data sets: user_hlq.RDZnnnn.*, where nnnn is a number that represents a single configuration.
Note that the input fields are verified, but invalid values are accepted (after a warning). This allows you to create all configurations on one system (the driving system), even if the naming conventions on the target system are different.
Also note that the values defined here are fixed for the life of this configuration. To change them, you must create a new configuration (which can be based on this one to avoid duplication effort for the variables that do not change).

The customization actions are grouped in three sections:
Each option will bring you to an input panel where you can specify values for the related variables. Note that the panels might not cover all possible configuration options to reduce complexity. See the Host Configuration Guide (SC23-7658) for a detailed overview of each available option.
Once you completed the various customizations, select option "G" Generate to create a set of tasks (called the work items) that will create the configuration files and do related actions (such as security definitions) based upon the specified values.
Generating the work items completes the first step of the customization process for this configuration, so the provided information will be saved for future use. The utility will prompt you for a meaningful name for this configuration.
The configuration has been modified and will be saved on exit Specified below is the default description for this configuration Modify if desired : RDzx.x Configuration Press Enter to continue |
Once the work items are generated and the configuration data is saved, you are brought to the panel that shows the defined configurations. This panel will be your initial startup panel from now on.

You can now edit each item (E or S command) to verify what it exactly does, and then execute it (A command). Some items will be executed by the utility (such as copying members). Other items will prompt you to do a manual action with the provided information (for example, updating PARMLIB members).
Also note that some items require authority that you might not have (such as RACF administrator). In this case, just give the person with sufficient authority the following information and ask that person to execute the related work items:
The utility supports more than just initial product configuration. It allows you to build various configurations, define values and work items for them, edit existing configuration files, run Installation Verification Procedures (IVPs), and collect debug information.
All these actions are described in detail in the provided help panels.
Doing the initial configuration of Developer for System z will give you an idea how the utility is designed. The key concepts you need to remember are:
