Getting Error while login to WebLogic Console Oracle Application R12 (12.2)
The Server is not able to service this request: [Socket:000445]Connection rejected, filter blocked Socket, weblogic.security.net.FilterException: [Security:090220]rule 2
Issue:
The error I encountered is related to a feature in WebLogic known as a connection
filter. This mechanism provides network-layer access control, enabling the
server to block unwanted communication based on various criteria.
Solution:
We need to update the connection filter value to 'allow' in the config.xml file located in the $EBS_DOMAIN_HOME/config folder
[applprod@cloner12 ~]$ cd $EBS_DOMAIN_HOME/config
[applprod@cloner12 config]$ ls -l config.xml
-rw-r----- 1 applprod dba 55688 Jun 18 22:37 config.xml
[applprod@cloner12 config]$ grep connection-filter config.xml
<connection-filter>oracle.apps.ad.tools.configuration.wls.filter.EBSConnectionFilterImpl</connection-filter>
<connection-filter-rule>cloner12.githesh.com * * allow</connection-filter-rule>
<connection-filter-rule>0.0.0.0/0 * * deny</connection-filter-rule>
Backup the config.xml
[applprod@cloner12 config]$ cp -rf config.xml config.xml_bk
And change the value from deny to allow
[applprod@cloner12 config]$ sed -i 's/<connection-filter-rule>0\.0\.0\.0\/0 \* \* deny<\/connection-filter-rule>/<connection-filter-rule>0.0.0.0\/0 * * allow<\/connection-filter-rule>/' config.xml
[applprod@cloner12 config]$ grep connection-filter config.xml
<connection-filter>oracle.apps.ad.tools.configuration.wls.filter.EBSConnectionFilterImpl</connection-filter>
<connection-filter-rule>cloner12.githesh.com * * allow</connection-filter-rule>
<connection-filter-rule>0.0.0.0/0 * * allow</connection-filter-rule>
Stop and Start the admin server
[applprod@cloner12 config]$ cd $ADMIN_SCRIPTS_HOME
[applprod@cloner12 scripts]$ ./adadminsrvctl.sh stop
[applprod@cloner12 scripts]$ ./adadminsrvctl.sh start
