Stand-alone configuration for z/OS
A stand-alone configuration, also known as a base configuration, requires little planning and is the simplest configuration you can use to deploy and run IBM BPM for z/OS .
The stand-alone configuration consists of a single node running an application server and one daemon server in a single z/OS system or logical partition (LPAR):
- The application server runs the administrative console, which you can use to deploy and run additional applications. The application server is managed independently from other servers.
- The daemon server is a unique server that runs constantly and has one controller region, which distributes server workload.
- A database management system, typically DB2 for z/OS, is required for storing the database objects.
The following figure shows a WebSphere Application Server for z/OS stand-alone configuration that has been extended with IBM BPM for z/OS functions.
Advantages of a stand-alone configuration
Use a stand-alone configuration if you want to isolate the test and production systems in your company. If the systems are not isolated, applications that are being tested in the test system might cause errors that can affect other applications on which your company depends.
You might choose to use a stand-alone configuration in the following scenarios:
- Your company is very large and you want to give each of your test groups a separate server in which to run applications.
- Your company runs production and test environments on one zSeries system.
For example, you might give the test group access to one server and give the production group access to all of the other servers.
- Your company is deciding whether to use IBM BPM for z/OS and you want to provide a small amount of resource for feasibility testing.
The other type of configuration that you can use for IBM BPM for z/OS is an ND configuration, which consists of multiple servers. A ND configuration is intended for a more sophisticated environment, and improves scalability and security throughout the system.
