When assembling your project team, be aware of the skills
required to implement WebSphere® Application Server
for z/OS®.
In assembling your project team, you should consider the skills
you need to implement WebSphere Application Server
for z/OS. This article discusses the recommended
skill set necessary to support the following configurations:
- Basic configurations
- Production environments
Documentation to support the z/OS skills
described in this article can be found at the following website: z/OS Internet Library
For basic configurations:
Below are the recommended
skills necessary to support a basic configuration:
- z/OS UNIX System Services and the hierarchical
file system (HFS) - to set up a functional HFS and UNIX environment
- eNetwork Communications Server (TCP/IP) or equivalent - to configure
connectivity for WebSphere Application Server for z/OS clients
and servers
- Resource recovery services (RRS) - to implement resource recovery
services and to support two-phase commit transactions
- Security Server (RACF®), or the security product
you use - to authenticate WebSphere Application Server
for z/OS clients and servers, and authorize access
to resources
- Secure Sockets Layer (SSL) - to enable security if desired (recommended)
- IBM Installation Manager, SMP/E, and JCL
- System logger - to set up log streams for RRS and the WebSphere Application Server for z/OS error
log
- Web server - to support HTTP clients if desired
- Workload management (WLM)
- Java and WebSphere Application
Server tooling - to support application development and deployment
Depending on the needs of the applications you deploy, you might
also need skills to configure the resource managers your applications
require, such skills might include CICS®, DB2®, IMS™,
and MQ.
For production environments:
As you move your
system toward a production environment, you need to have the following
system skills available:
- Automatic restart management (ARM)
- System Automation, if you have it installed, or whichever automation
you prefer to use
- Sysplex if you plan to use WebSphere Application
Server for z/OS in a cell that spans systems
- Sysplex Distributor (part of eNetwork Communications Server),
if you plan to create a high availability environment
- RMF™ or other performance measurement systems
