DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

We did a fresh installation of UIM 20.4 on Windows 2019 server. The installation finished successfully but the wasp probe on Primary UIM server is in error state and does not come up.

I see the same error in the wasp log file as shown in the below tec doc: wasp doesn't start after UIM clean install. Fatal error! (broadcom.com)

I checked and the antivirus on the server is already disabled.

Error seen in wasp.log

Environment

Release :

UIM : 20.4.0

OS : windows 2019

Component : UIM OPERATOR CONSOLE - WASP & CORE

Cause

In some environments war files are not extracting properly

Resolution

- Go to <webapps> section and check whether each webapp section contains a property called doc_base

If not there add doc_base = <webapp name>
for eg:
<uimapi>
reloadable = true
cross_context = true
load_on_startup = true
unpack_war = true
doc_base = uimapi
path = /uimapi
</uimapi>
