UVMS commands display Java error for non-root users

Issue/Introduction

On Unix, the installation of UVMS must be done with root to add the init.d startup script.

However, if, after the installation, the files are not assigned to a non-root UVMS user, commands show error messages or fail completely for non-root users.

For example, the command unilst AUDIT executed with a non-root user will lead to the following messages and errors:

With file permissions 755:

/<UVMS_folder>/<server_name>_MgtServer/bin/unilst
-rwxr-xr-x. 1 root root  3176 Mar 19 15:44 unilst

This will show a lot of messages, but the result appears at the bottom (see last 3 lines in bold):

$ ./unilst AUDIT

Environment

UVMS on Linux

Cause

Insufficient rights

Resolution

Solution:

1. Install UVMS with a non-root user. 

This works fine but the init.d script will not be installed, so UVMS will not automatically start after a server restart.

 

2. Install UVMS with root, but assign all files to a non-root user after the installation

In /<UVMS_folder>/ containing the directory ../<server_name>_MgtServer/ run the following command:

chown -R uvms_user:uvms_group *

uvms_user and uvms_group can be any user/group that needs to do administrative tasks on UVMS.
