Environment

OS: Windows only
Release : 6.x
Component : DOLLAR UNIVERSE
Subcomponent: du_upgrade_toolkit

Cause

Windows System issue, somehow the operation REN fails as the permissions must not be properly set.

Resolution

Workaround 1:

The du_upgrade_toolkit will no longer be delivered ( latest version being 6.10.21).
So we propose to modify the script causing the issue.

To do so:


Modify the script du_upgrade_toolkit/bin/unideployjre.bat and add the line
"timeout 3 /nobreak"

before the line
"ren jre6 jre"

Workaround 2:

Use the uniexp / uniimp that are delivered with the UVMS kits for Windows / Linux ( no need to have the UVMS installed to use them).

Solution:

Check with Operating System Support / Admins why the rename folder operation "ren jre6 jre" would fail after having unzipped the file before as the error is returned by the system
