ORA-12541: TNS:no listener after upgrading from 11.1.0.6 to 11.1.0.7

Question

After upgrading from 11.1.0.6 to 11.1.0.7, I get the error: ORA-12541: TNS:no listener.
I have attached my tnsnames.ora, listener.ora and my sqlnet.log.
I have tried deleting the listener and re-adding it and I get the same error.
I have tried adding a new database and it errored at 97% because it couldn’t connect to the listener, but still seemed to create the database.
Any suggestions would be appreciated

Hi,
What is your ORACLE_SID name of your database. Have you checked in given above output there is two things:
1.
Service "orcl.us.oracle.com" has 1 instance(s).
Instance "orcl", status BLOCKED, has 1 handler(s) for this service...
Service "orcl_XPT.us.oracle.com" has 1 instance(s).
Instance "orcl", status BLOCKED, has 1 handler(s) for this service...
The command completed successfully
The status BLOCKED is coming instead of READY
2. From
+"+
+my listener.ora file:+
+# listener.ora Network Configuration File: C:\Oracle\product\11.1.0\db_1\network\admin\listener.ora+
+# Generated by Oracle configuration tools.+
+LISTENER =+
+(DESCRIPTION_LIST =+
+(DESCRIPTION =+
+(ADDRESS = (PROTOCOL = TCP)(HOST = tebxjt)(PORT = 1521))+
+(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))+
+)+
+)+
Here what i feel complete linstner.ora should be have two parts one LISTENER and another SID_LIST_LISTENER :
LISTENER =
(ADDRESS_LIST=
     (ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))
     (ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))     
SID_LIST_LISTENER=
(SID_LIST=
     (SID_DESC=
               #BEQUEATH CONFIG
(GLOBAL_DBNAME=salesdb.mycompany)
(SID_NAME=sid1)               
(ORACLE_HOME=/private/app/oracle/product/8.0.3)
In your case SID_LIST_LISTENER part is missing.
In this part you have to set SID_NAME and ORACLE_HOME value of new 11g home.
Hope this will help you.
