I have installed 18C. it was running fine. After a couple of weeks - when i re-started the client - Oracle SQL Devloper produced the following error:
"RA-12528: TNS:listener: all appropriate instances are blocking new connections".
What is the solution to this error? Re-install oracle? Re-install Oracle SQL developer on the client? Any alternative? Please help.
I have used google, but in vain.
Check the status of the listener by
[oracle#hostname ~]$ lsnrctl

Welcome to LSNRCTL, type "help" for information.
LSNRCTL> status
One method that should resolve this problem is to restart (bounce) the LISTENER:
LSNRCTL> stop
LSNRCTL> start
Then restart your instance:
sqlplus with sysdba privileges
SQL> startup

I'm trying to import the full database to a pluggable database in Linux OS. I am getting the below error while connecting to the schema.

I tried pinging to TNS and listener services seem to be up.
Does anyone face this issue or can anyone help me to understand what could be the solution for this?
None of my browser are working whenever I query in browser I get the message "ORACLE DATABASE 10g EXPRESS EDITION LICENSE AGREEMENT". What to do?
I too faced same issue and fixed the issue by following these steps. Please have a try.
From Start | Run open a command window. Assuming your environmental variables are set correctly start with the following:
C:\>sqlplus /nolog

Enter password: <enter password if will not be visible>
Connected.
SQL> Exec DBMS_XDB.SETHTTPPORT(3010); [Assuming you want to have HTTP going to this port]

SQL>quit
Now restart the PC and check.
I installed Oracle 11g Express Edition Release 11.2.0.2.0 - 64bit to a CENTOS 7 machine and opened up SSH so I can configure the machine from my windows laptop via putty. 11g installed successfully, but I can't seem to access 11g XE GUI from the web browser (http://127.0.0.1:8080/apex). I'm following this guide and haven't ran into any problems until this.
[root#localhost /]# sqlplus /nolog

Now when I navigate to http://127.0.0.1:8080/apex in Chrome, I'm hit with:
This site can’t be reached
127.0.0.1 refused to connect. Try: Checking the connection Checking the proxy and the firewall ERR_CONNECTION_REFUSED
I tried disabling my firewall on both my Linux machine and my windows machine, but it didn't have any effect. Any ideas on why I can't access it?
Refer to the below thread.
Oracle 10g express home page is not coming up
In another case, adding 127.0.0.1 into the hosts file for windows resolved my issue.

ERROR:ORA-12541: TNS:no listener
So please tell me where this is wrong
Below are the possibilities for this:
1) Listener might be down
2) When database is not up, 'TNS: no listener' error appears
3) If the TNS entries are not correct.
Ex: The TNS entry of crbt_new database might have the port number mentioned as 1531, but in real the Database would be listening on port 1521
