Invalid server name oacore_server1 ( Remove and Add Managed servers )

Issue: 

While starting using adstrtal.sh script we have encountered below error:

Invalid server name oacore_server1

Why:

Found this managed server some how not showing in Weblogic Admin Console.

Solution :

First removed that managed server oacore_server1

perl $AD_TOP/patch/115/bin/adProvisionEBS.pl \
ebs-delete-managedserver \
-contextfile=$CONTEXT_FILE \
-managedsrvname=oacore_server1 \
-servicetype=oacore \
-logfile=/home/applmgr/oacore_server1_remove.log

Output:

Enter the APPS Schema password:
Enter the WebLogic AdminServer password:
ManagedServer oacore_server1 deleted successfully.
$


Second , add the managed server oacore_server1

perl $AD_TOP/patch/115/bin/adProvisionEBS.pl \
ebs-create-managedserver -contextfile=$CONTEXT_FILE \
-managedsrvname=oacore_server1 -servicetype=oacore \
-managedsrvport=<PORT> -logfile=/home/applmgr/forms_server1_add.log

Third sync it with .conf file

perl $FND_TOP/patch/115/bin/txkSetAppsConf.pl -contextfile=$CONTEXT_FILE \
-configoption=addMS -oacore=oacore_server1:<PORT>

After that able to start oacore_server1
