Installing maintenance as an installer and changing the ownership of profile related files
The installer can install maintenance packages for WAS that includes required service for existing profiles that are owned by a non- user. Installing a maintenance package that contains service for a non-root profile makes the installer owner of any new files that the maintenance package creates. The following example shows how to install the maintenance and change the ownership of the new files so that a non-root user can successfully start WAS. This task assumes a basic familiarity with the Update Installer wizard and system commands.This task uses the following terms:
- Root users refers to:

- Installer refers to a root user or a non-root user.
Before you can update a profile, install WAS and create a profile.
Overview
This example assumes that the installer:- Applies service that creates new files in a profiles directory that the wsdemon non-root user owns.
- Changes ownership of new profile files to the wsdemo non-root user.
If the installer does not change ownership, when the non-root user starts WAS, the appserver encounters an error and issues a message that is similar to the following example:
ADMR0104E: The system is unable to read document cells/express1Cell/nodes/express1/node-metadata.properties: java.io.IOException: No such file or directory
Procedure
- Run the Update Installer wizard to install maintenance packages for WAS.
The installer owns the new files that the Update Installer wizard creates under the profile_root directory. The original owner of existing files continues to own those files that the Update Installer wizard only modifies.
- Reassign ownership of the entire profile directory to the wsdemo non-root user.
The profile_root variable in the following examples is the profile directory that the non-root user owns.
Issue the chown command.
chown -R wsdemo profile_root
Follow instructions in the Windows documentation to reassign ownership of the profile_root profile directory to the wsdemo non-root user.
Results
The installer installed maintenance that creates new files in a non-root user profile directory and changes ownership of the new files to the non-root owner.
What to do next
The non-root user can start WAS without receiving the ADMR0104E error message.Installing maintenance packages
