Products

Issue/Introduction

Found the following error when entering the zwe install command to install version 3.0 of Zowe:

Error ZWEL0157E: Zowe dataset prefix (zowe.setup.dataset.prefix) is not defined in Zowe YAML configuration file.

However, zowe.setup.dataset.prefix is specified in zowe.yaml file.  

Environment

ZOWE v3

Cause

ZOWE.yaml has the following setting, however, filesystem for nodeJs was not mounted for this system.

node:
  # **COMMONLY_CUSTOMIZED**
  # Path to your node.js home directory
  home: /usr/lpp/nodejs

 

 

 

Resolution

Mount the filesystem for nodeJs on this system. Then rerun the zwe init command to create Z/OS dataset. 

Additional Information

Running none supported NodeJs version or YAML file indentation issue could also cause the "dataset prefix not defined" error.
