Hi,

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

@wlsdmsupport Hi, I was able to run and configure WLSDM smoothly.
Thank you very much for the excellent and swift work!

@blanchettevdm said in import / export WSLDM configuration:

@fevzi-korkutata-wlsdmteam

Thanks Frevzi! True! a full reset will be a lot easier, although that brings another questions.

When you import configuration from another domain, is it a full overwrite ?

Thanks for your prompt answer…

You’re welcome. Yes, deleting the WLSDM runtime folder (make sure AdminServer is not running) is the easiest and safest method to import WLSDM configurations.

For your second question; yes it is a full overwrite. But remember; when you reset the config, there is nothing to overwrite 🙂

But at least; import is working as; "If same settings exists; update with the new one, if new config available add as new and keep already existing settings.

Finally, We use import feature all the time to facilitate WLSDM wizard completion and setting up a standart WebLogic domain monitoring configurations.

Hi,

Default interval is 120 seconds and you can change this value in “system.monitoring.genericmbean.harvest.frequency” property as below.

PS: If you change this value, it will effect all “Custom MBeans”.

@wlcommunityusers

Hi,

Finally, I found the solution.
I changed java.security in WL-OPC disabling jdk.tls.disabledAlgorithms like this:

b0d4cae9-48f2-4ce0-9bf1-0afdaf93dcde-image.png

And then I removed all the arguments in JAVA_OPTIONS to default OPC installation.

I restarted OPC and I could add the domains without any problem.

Regards.

@djviolli said in LDAP Configuration Access:

Problem solved by the support team, due to using the OUD for access, a base version was made!
I congratulate the WLSDM team for their attention and timely solution.

Thank you @djviolli very supportive and valuable feedback from you to the community. 👏

Hi @sergei

Thank you for reaching out to us. Yes, WLSDM is totally free and almost fully featured for the developers. And it is called developer edition.

Could you please check your domain again and let me know is “Change Center” section is available or not? Please take below screen capture as reference.

fdf2d6f6-503b-4b58-a971-8948614095c6-image.png

If it is available on your domain; it is still production mode and you can not use free developer edition. Please check your domain and let us know the result?

Also, you still want a license you can contribute to us and win a free enterprise license; please follow this page for the submission: https://wlsdm.com/get-free-enterprise-license

Hi,

We fixed this issue in v3.9.2. If you upgrade the WLSDM domain v3.7.2 to v3.9.2 you will not face this issue any more.

@can-sahin-wlsdmteam

Hi,

Could you try to add below parameter in AdminServer JAVA_OPTIONS please?

This parameter is purging WLSDM DB every AdminServer startup. Try this then let us know the result.

-Dwlsdm.system.dbShrinkOnStartup=true

Hi,

Try to hard restart OPC by using opc command. After restarting OPC the problem should have resolved? Could you please confirm the result?

We’ve created an issue to solve the problem permanently.

@wlcommunityusers said in WLSDM Config- New managed server:

Hi,

We have added a new managed server to the domain. We want to configure alerts(Datasource, Backend Monitoring etc) like we configured for previous managed server. Please suggest.

Current config:
AdminServer
ManegedServer1
ManegedServer2

Regards.

Hi,

You can include new server to current configurations in “Response Time” monitoring but you need to add new back-end systems configuration for new server.

Please check below screen captures.

Response times configuration for newServer:

Go to “Configurations > Monitoring & Diagnostics” in WLSDM menu Follow below navigation and click “edit” button Select ManegedServer2 then save

reponse1.jpg

Hi,

We have resolved the DB purge issue in version 3.9.2. Which version is this WLSDM domain?

You have two options;

First is to upgrade WLSDM v3.9.2. (Keep in mind while you are opening the AdminServer; the purge operation would start automatically and it can took a lot time because of your db size)
https://wlsdm.com/docs/README#IX.Upgrade&Reinstall&Uninstall

Second is fresh re-installation which is explained as below steps. (Remember to take current configurations; if you have license issue we have already sent the trial license to skip config wizard)

Export WLSDM Configuration; follow the steps below

wlsdm_configuration.jpg

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

Hi,

WLSDM cron takes several minutes to return cycle. Reduce some minutes, Example 1430 rather then 1440.

Hi,

Did you upgrade the domain? Your latest screenshot says your WLSDM v3.7.2 but WL-OPC says WLSDM v3.9.2.

You can follow the below provided solution.

Check two way access between WL-OPC and WLSDM
WLSDMHostname$ telnet OPCHostname 8080
WL-OPCHostname$ telnet WLSDMHostname 7001 Open problematic domain’s wlsdm_agent.jar with winrar and check WLSDM-version in “META-INF> MANIFEST.MF” file. If there is old version just replace wlsdm_agent.jar with the new version in $DOMAIN_HOME\wlsdm_agent\ Unregister problematic WLSDM domain from WL-OPC Complete WLSDM installation wizard without WL-OPC registration Register WLSDM domain to WL-OPC in WL-OPC “Administration> WL Domain” page. If the problem is not resolved please send us $WL-OPC_HOME\bin\WLOPC\logs with the zip file

Kind regards.

Hi,

On the other hand, I’m trying to configure a script to be executed once I have a stuck thread alarm.
Is it possible to do that?

Yes, you can set alarm to scripts. Please check below tutorials.

Hi,

You can change the JFR repository directory using the following JVM option:
WLSDM must delete those temp files which is older than two days (48 hours).

-XX:FlightRecorderOptions=repository=WLSDM/temp/JFR ( see: https://wlsdm.com/docs/#VI.Installation )

If you choose not to define (or remove) this JVM option, by default the files will be stored under the operating system temporary directory.

For more information see: https://docs.oracle.com/javase/8/docs/technotes/tools/unix/java.html
repository.png

Also, jfr files are static profiling files, not library files. You can delete them safely even runtime.

For the second question: You can achieve that using the “Downtime” feature:

1 – Go to WLSDM console / “Monitoring & Diagnostics” page.

schedule.png

2 – Open the page operations and click the “New Scheduled Job / Downtime”
newschedule.png

3 – Configure the downtime and click save.

At this point, you have two action option:
1 – Stop all notifications but keep monitoring
2 – Stop all monitoring

Oh, that’s lovely, thank you very much!
Have installed 3.9.1 in out sandbox environment after receiving the newsletter last week, will give this a shot right away!

Hi Can,

This error is the wrong path for java in setenv.properties file configuration.
Because in Linux alternative link using for java path.
If you are using this command in terminal. “echo $JAVA_HOME” then it gives a true java path.
ex: echo $JAVA_HOME --> /usr/lib/java/jdk1.8.0_201
In setenv.properties file JAVA_HOME line change with your full java path.

Then you can start WL-OPC.

Regards.

Hi Karim,

You have Out of Memory error while opening this managed server. Please check below error in your managed server log.

You had better tune and optimize your WebLogic environment or increase server memory.

Kind Regards.

Hi,

You can follow WLSDM installation instructions in https://wlsdm.com/docs/#IV.Installation page.

There are notes as below for installation:

I. Known Issue: After the complete WLSDM installation if the “Smart Dashboards > JVM System Resources” page is not working well and does not show the metric values properly then add “-Djavax.management.builder.initial=weblogic.management.jmx.mbeanserver.WLSMBeanServerBuilder” JVM argument to the relevant Managed Server(s) and restart the server(s).
II. Do not install agents for whole servers. same cluster or same machine not needed WLSDM agent (as below screenshot).
III. Care “with Nodemanager” and “without Nodemanager” parameter step in wlsdm installation document then use one of them which are you using.

Hi,

It looks like SMTP Server that you are using requires authentication.
535 Authentication required com.sun.mail.smtp.SMTPSendFailedException: 535 Authentication required

Please make sure the SMTP username and password are set on the WLSDM.

smtp1.png

After that, you can check the setting by using the “Test Email Settings” button under the page operations dropdown menu.

Hi,

OPC default port is 8080, When you need to register domain to OPC first of all; check firewall rules for below ports with telnet.

OPC and agent both are communicating each other you need mutual firewall request.

From: ${WLSDM_AGENT’S_IP}
To: ${OPC_SERVER’S_IP:8080}

From: ${OPC_SERVER’S_IP}
To: ${WLSDM_AGENT’S_IP:WEBLOGIC_ADMIN_PORT}
