SOLVED WLSDM and OPC licence issue

[wlcommunityusers]

Hi,

I’m trying to configure many domains with WLSDM.
Many of then are asking for a valid licence instead to asking me for OPC URL.
Could you please send me a step by step tutorial to integrate WL-OPC and WLSDM?

It seems WL-OPC’s sent the licence to WLSDM but it doesn´t take it.

In the other hand, I found many errors in WL-OPC logs

Hi,

I tried doing a fresh install of WLSDM console and the first error I see is:

####<Oct 21, 2021 3:55:48 PM ART><INFO><WLSDM><BEA-000000><WLSDM job scheduler initialized successfully.>

####<Oct 21, 2021 3:55:51 PM ART><INFO><WLSDM><BEA-000000><WLSDMOPCServer.RegisterController:: Registration ignored. System property not enabled.>

####<Oct 21, 2021 3:56:19 PM ART><WARNING><WLSDM><BEA-000000><Has No Valid License. Caused by null/wrong license info.>

####<Oct 21, 2021 3:56:48 PM ART><WARNING><WLSDM><BEA-000000><Has No Valid License. Caused by expire.>

I have network communication to OPC using wget and telnet.

Hi,

Please follow the steps below and let us know the result.

1- You can use the ulimit command to view the soft limit and hard limit separately.

$ ulimit -n

Modify the following file to change the system limit

sudo vim/etc/security/limit.conf

For example, we set the limit for opening files for user’s running account username, add in the above file

username soft nofile 63536
username hard nofile 63536

2- Open the $JAVA_HOME/jre/lib/security/java.security file in a text editor.

Change the line:
securerandom.source=file:/dev/random
to:
securerandom.source=file:/dev/./urandom

3- WL-OPC shutdown & start

Regards.

Please install WLSDM again by following the steps below.

1. Shutdown AdminServer
2. Delete WLSDM Runtime Folder (If background information is not important; in this case the past will delete)
3. AdminServer start
4. Complete WLSDM configuration wizard by importing export configurations.

Re-installation procedure also available in here : https://wlsdm.com/docs/README#IX.Upgrade&Reinstall&Uninstall
