Server data sets reference

Zowe includes a number of files that are stored in the various data sets. See the following tables for the storage requirements and purposes.

Runtime data sets

The following data sets comprise the runtime, read-only data set content that can be used by multiple Zowe instances of the same version. These are either delivered by an SMP/E install, or by running zwe install when using the z/OS convenience build of the Zowe servers.

Custom data sets

The following data sets are designed to be used by a single Zowe instance. These are created during post-install setup, and include temporary content as well as data sets used for extensions of Zowe.

Unix Runtime Directory

The unix directory listed in the Zowe YAML as zowe.runtimeDirectory is the read-only directory which holds most of Zowe's code. Its subdirectories and files are subject to change without notice, except the following files:

Name	Purpose
example-zowe.yaml	Example Zowe YAML for first-time installation
manifest.json	States the Zowe version and the versions of the components within that Zowe release
bin/zwe	The zwe command line utility

Unix Instance Directories

The following directories are designed to be used by a single Zowe instance. These are created and populated when Zowe is running.

Name	YAML Property	Purpose
Log Directory	zowe.logDirectory	Contains log files for some components and extensions.
Workspace Directory	zowe.workspaceDirectory	Contains persistent configuration content for components and extensions.
Extension Directory	zowe.extensionDirectory	May contain extensions installed into Zowe.
