Creating instances for DataStage

A parallel engine (PX) DataStage instance is the runtime environment that DataStage jobs run on. When DataStage is installed, one default PX instance is automatically created. The size of the default instance is the size that was specified when DataStage was installed, and can be small, medium, or large.

The default instance is provisioned under the administrator account, so only users with administration permissions can view or edit the default instance. The default instance is named ds-px-default. Every DataStage user has access to the default instance. Jobs that have no environment that is associated with them automatically run on the default instance.

More instances can be created by users whose role has the correct permissions to do so. Administrators can create new roles with permissions as needed. Each PX instance has its own conductor and compute pods to ensure the DataStage workloads are separate. Different users and user groups can be assigned to each PX instance. Every instance can access ds-storage, which is used for storing project metadata and resource files. This mounted PV should not be used to persist user data that needs to be accessible only from a particular px-runtime instance.
