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 Web site: 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)
- SMP/E and JCL
- System logger - to set up log streams for RRS and the WebSphere Application
Server for z/OS error
log
- Webserver - 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
