Can you show the parameters you have used?
Did you provide these 3?

1) hostname
2) port
3) SID

Can you ping the hostname from the command line?

by: epifanio67Posted on 2009-08-06 at 15:39:53ID: 25038779

hey mrjoltcola...

thx so much

1. localhost.localdomain
2. 1521
3. DEMO11

all system wide variables are set correctly

Ok. Your listener may not be up. Did you configure a listener when you setup your local database? If so, is it started?

Is this Windows or UNIX?

From DOS or UNIX prompt list the services:

lsnrctl services

by: epifanio67Posted on 2009-08-06 at 16:47:41ID: 25039053

thx mrjoltcola...

the local database DEMO11 was configured during initial install.
I am on the same machine where Oracle resides.
OS: centOS 5.3

see command results:

the weird part of all this is that the DB has been working ok for days... now, all of sudden I am having problems... this morning when I logged in, problems started... no changes made to it at all....

Looks like a syntax error in listener.ora

Line 2 is missing a #

by: mrjoltcolaPosted on 2009-08-06 at 19:13:59ID: 25039589

Or there was a cut and paste error.

Try this..

Invoke NETCA and drop the listener.
Create new one, but first check for firewalls.
Firewalls should be OFF.

Also in Listener.ora register the database:

Backup LISTENER.ORA file!!!!!!!

In ...\network\admin open listener.ora

see

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\Ora10g)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = test)
(ORACLE_HOME = D:\Ora10g)
)
)

Add the entry
(SID_DESC =
(SID_NAME = test)
(ORACLE_HOME = D:\Ora10g)
)
with regard to the particular Oracle Home and SID Name.

In Oracle 11g you have to create from scratch in the listener.ora file the section

SID_LIST_LISTENER =
&..

mentioned above.

Restart the listener:
c:>lsnrctl stop
c:>lsnctl start

by: epifanio67Posted on 2009-08-07 at 08:51:43ID: 25044047

thx mrjoltcola... I can't believe that line was not commented. I looked at that file like a thousand times.... I also cleaned the port line (moved it to same line)...

thx shwerter... not sure if I understand "Invoke NETCA and drop the listener"
1. Firewall is off
2. added SID_LIST_LISTENER to listener.ora (see below)
3. then, I tried to stop lsnrctl and got message below

everything was working just fine and all of the sudden it freaked out.. this is simulation environment I do shut things down every day...... does this happen if you don't shut down properly?

:-( tears

thx

Hello mrjoltcola and shwertner,

I got sqldeveloper to connect... may be it was the listener.ora when added SID_LIST_LISTENER... to be honest I am not sure...
I think my problem is the process to start/shutdown Oracle.

here is what I did to make it work:
TO START:
$ORACLE_HOME/bin

1. . oraenv <enter SID>
2. sqlplus "/ as sysdba"
SQL> startup
SQL> exit
3. lsnrctl start
lsnrctl exit
4. emctl start dbconsole
5. launch sqldeveloper

TO SHUTDOWN:
1. exit sqldeveloper
2. at terminal
. oraenv <enter SID>
3. sqlplus "/ as sysdba"
SQL>shutdown immediately
SQL>exit
4. lsnrctl stop
lsnrctl exit
5. emctl stop dbconsole

is this the process you guys follow to start/shutdown the Oracle "uncomplicated" beast?

thx

>>is this the process you guys follow to start/shutdown the Oracle "uncomplicated" beast?

Actually, no I automate the startup/shutdown using the dbstart utility. Its a bit of a different question, but I can point you through to it. You might not like it. If you ask a related question ro call my attention to it I'll work through it with you. Takes 5 minutes or so for an experienced Oracle / UNIX admin, but the first time its a bit mysterious for some.

On UNIX it depends on the /etc/oratab and a script in your init scripts (/etc/init.d) that calls $ORACLE_HOME/dbstart

As far as your original, problem, I think perhaps it was a simple cut and paste error when you edited the file. Who knows?

by: schwertnerPosted on 2009-08-07 at 12:04:46ID: 25045946

In Oracle 10g I got same errors due the missing instance entry in Listener.ora
Can not explain why, how .... but after working with Listener everything is OK.
