Hi @DENISKA80 ,

Has SSL been enabled? I believe that your SSL certificate expired, and you have to renew it.

DENISKA80

I cant remember we have ever enabled it.

How can we check it?

unfortunately i have no access to metalink now(

Hi @DENISKA80 ,

Are you able to access the WebLogic Administration Console as weblogic (or any other administrator)?

If so, in the Domain Structure panel expand Environment > Servers > AdminServer, and check whether the SSL checkbox is ticked. Then do the same for bi_server1 to understand if SSL has been enabled or not.

Then, if you expand Environment > Machines, you can monitor the NodeManager status. When everything is working as expected it should display Reachable as status.

"Are you able to access the WebLogic Administration Console as weblogic (or any other administrator)?"

Yes I can start weblogic manually

"If so, in the Domain Structure panel expand Environment > Servers > AdminServer, and check whether the SSL checkbox is ticked. Then do the same for bi_server1 to understand if SSL has been enabled or not."

Not enabled

"Then, if you expand Environment > Machines, you can monitor the NodeManager status. When everything is working as expected it should display Reachable as status."

Status Inactive

Listen port 9506

Type SSL

I can even start bi_server1 with "startManagedWebLogic bi_server1" command and see that it has Running state in EM but all of the services in biinctance are down. When I trying to start it(obis1 f.e.) i get the same error from the 1st post

Hi @DENISKA80 ,

NodeManager status Inactive: this is the issue that you must fix!

I recommend to stop/kill all your OBIEE processes. Then start the NodeManager manually using the startNodeManager script (do not close the command prompt otherwise NodeManager will stop). Do you get any error message?

If it started properly, then start the Weblogic server manually using the startWeblogic command. If it completes successfully, then login to the Administration Console, confirm that the NodeManager is reachable, and start the managed server (bi_server1) from the console.

DENISKA80

Restarted the whole machine.

Opened cmd with admin rights and started nodemanager

c:\Oracle\Middleware\Oracle_Home\user_projects\domains\bi_domain\bin\startNodeManager.cmd

(Secure scoket listener started on port 9506)

Opened cmd with admin rights and started weblogic (during starting entered credentials)

c:\Oracle\Middleware\Oracle_Home\user_projects\domains\bi_domain\bin\startWebLogic.cmd

In weblogic console status of the NodeManager - Inactive

RajeshPolavarapu-Oracle

@DENISKA80 Can you please upload the screenshot of the weblogic console where you see the status of the nodemanager.

Also I advice you to raise an SR with support for this issue. So, we can thoroughly study the logs, debug the issue and fix your connectivity issue between admin server and nodemanager.

Thanks.
