2.9.1 Example of system configuration when multiple environments are configured on one machine
This subsection describes an example of classifying the development environment in multiple environments and the HCSC-Manager environment in each cluster.
- Organization of this subsection
(1) Classifying development environment into multiple environments
By assigning the CSCMNG_HOME environment variable to each test environment to be used, you can configure multiple test environments on one machine. The following figure shows an example of configuring multiple operating and execution environments on the machine for development:

However, since you cannot use the HCSC Easy Setup functionality when you assign CSCMNG_HOME environment variable to each environment, you must build the environment one by one from the HCSC server setup.
Also, if you assign the CSCMNG_HOME environment variable, you cannot use even the HCSC production environment Easy Setup functionality (cscsetup command). Note that when setting up an environment using the HCSC production environment Easy Setup functionality, assign the CSCMNG_HOME environment variable after unsetting up, and then again set up an environment without using the production environment setup functionality.
(2) Classifying the HCSC-Manager environment in each cluster
While handling multiple clusters in a large-scale configuration, you can perform localization when error occurs such as though the repository is destroyed due to classification of the repository; the operations are executed without being affecting other clusters.
Hitachi recommends you to execute operations in multiple clusters and to classify operating environment in each cluster when configuring execution and operating environments on different machines.
The following figure shows an example of classifying the operating environment in each cluster:
