Oracle 11g Express Error ORA-12505, TNS: listener does not currently know of SID given in connect descriptor

I am facing problem with Oracle 11g Express hosted on Linux Centos 6.4. This server is relocated from one place to another, this relocation changes the IP of server.
We have changed the IP in tnsname.ora and listerner.ora files. After these changes when we are trying to connect to database instance from server we are getting error “Connected to idle instance”. If we are trying it to connect from client using SQL developer we are getting error “Status : Failure -Test failed: Listener refused the connection with the following error: ORA-12505, TNS: listener does not currently know of SID given in connect descriptor”.

We have restarted this server and database multiple time (through option Start and Stop database under Oracle menu) multiple time, but still we are getting the same error.

Solution 2

This error is usualy about Connection String and name u add on the end.

SERVER=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort))(CONNECT_DATA=(SERVICE_NAME=MyOracleSID)));

So check SID name 1st then other things.
