Issue Encountered

While accessing the WebLogic Admin console <http://<Apps_tier_public_IP>:7001/console> I encountered with the following error:

Error: “The Server is not able to service this request: [Socket:000445]Connection rejected, filter blocked Socket, weblogic.security.net.FilterException: [Security:090220]rule 2”

Also Check Our Blog Post on OCI Migration.

Root Cause

The error I encountered is due to WebLogic offers a concept called “connection filter“.  Connection filters provide network layer access control and allow the server(s) to block unwanted communication based on different criteria. To know more about the Weblogic Connection filter click here.

You can check the WebLogic connector filter configuration under the config.xml file. To know more about config.xml check here

Note: config.xml is a file that contains all the WebLogic configurations

In the above config.xml file, you can see that it is blocking the connection for 0.0.0.0/0 where 0.0.0.0/0 is nothing but public internet.

Note: Using Weblogic Connection filter you can also whitelist particular IP

Fix

1)Open  the config.xml file

(/u01/install/APPS/fs1/FMW_Home/user_projects/domains/EBS_domain/config)

2)Backup your config.xml file before making any changes

eg: $ cp -R config.xml config.xml_bkp

3)Search for connection -filter-rule

4)Change the string “deny” to “allow”

5)Save the config.xml file & bounce the Application services’

Now you will be able to access the WebLogic console!!!
