Multiple extproc entries in listener.ora

Hello gurus and friends,
I have two versions of Oracle
(8.1.5 and 8.1.6) running on the
same server.
Is it possible to set up a single listener
serving both instances to have 2 different
extproc services with differnet locations
for oracle home.
If I don't do this, and just have one
extproc, it invariably points to the wrong
oracle home and errors immediately.
Adeeva.

Yes this is possible. Consult the Net8
Administrator's guide for the full details.
In short you will need to:
1. use the 8.1.6 listener
2. configure the 8.1.6 listener.ora file to include 2 separately named extproc addresses
in this example I use the 0 suffix for 8.1.5 and 1 for 8.1.6
3. In the SID_DESC list make sure you use a
full path to the program for the PROGRAM
attribute. If you don't then the 8.1.6
listener will use the 8.1.6 version of
extproc for the 8.1.5 instance.
4. Each tnsnames file (8.1.5 and 8.1.6) must have the appropriate extproc entry. I've included the one for 8.1.5 below.

IPC entries in the listener.ora

My listener.ora looks like the following,
LISTENER =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(ADDRESS = (PROTOCOL = TCP)(HOST = server1)(PORT = 1521))
Can I remove the IPC entries in the listener.ora?

Can I remove the IPC entries in the listener.ora?I give up.
Can you?
FWIW, you can remove the whole listener.ora file & the listener will still start & run without error.
How do I ask a question on the forums?

Although rest of entries refer to network services(Database name) and host address and protocol etc.
what these above refere to.
Please clarify me in this.

What's wrong with my listener.ora?

Hello.
I must say I've never understood how listener.ora works (it used to work but someone modified it), but by now it'd be enough to know what's wrong with this:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC2))
(ADDRESS_LIST =

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = CSR2)
(ORACLE_HOME = /opt/oracle/product/9.2.0)
(SID_NAME = CSR2)
My problem is that when I try to connect from my PC "sqlplus csr_admin@csr2/csr" I get "ERROR: ORA-12154: TNS: could not resolve service name"
This is my entry in my local tnsnames.ora:
CSR2.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = zippo)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = CSR2)
An this, the entry in the entntry at the server's tnsnames.ora:
CSR2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = zippo)(PORT = 1521))
(CONNECT_DATA =

It's funny but the date I posted this topic isn't OK (more than 3 years ago)

I'm guessing that my listener.ora file has a ")" in the wrong place or something to that effect. Would anyone mind pointing this out for me?

Please help.

I am seeing that the VIP is used. Is this OK or should the public IP be used?? yes,its ok to use both.

Listener.ora question

Sorry if this is a duplicate question, as I'm in a big hurry.
DBCA added my public ip to my listener.ora on all my rac nodes about two years ago. It's been running fine for the most part, but now I'm wondering if it's been causing some hanging issues during both planned and un-planned shutdowns.
The VIP is the correct way to go. I just hadn't noticed that the public ip was also in it. Should I remove it? Should I change it to the VIP ip?
Here's the listener.ora for on node.
LISTENER_TRAC201 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = trac201-vip)(PORT = 1621)(IP = FIRST)) <-- VIP obviously
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 138.72.249.161)(PORT = 1621)(IP = FIRST)) <-- Public ip of host.
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)

138.72.249.161 -> that's public IP, right?
if VIP Failover Take Long Time... after stop listener or...
because "lsnrctl stop" listener has to wait for TCP timeout before it can check next address.
Oracle recommend to use IPC address first
LISTENER_TRAC201 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = trac201-vip)(PORT = 1621)(IP = FIRST)) <-- VIP obviously
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 138.72.249.161)(PORT = 1621)(IP = FIRST)) <-- Public ip of host.
Example:
$ lsnrctl status
LSNRCTL for Linux: Version 10.2.0.4.0 - Production on 26-AUG-2009 01:57:01

Tnsnames.ora / listener.ora files on Oracle Standby Database

Hi I am configuring an Oracle Standby Database to my production system 4.7 and Oracle 9.2.0.4
My production server is: PR01
Database SID: PRD
Standby database server is: PRDR
Database SID: PRD
I have already configured the server to a standby database offline backup. Was generated the control files of the standby database and the database is in standby mode.
Now I will create a script to start the synchronization of offline redolog from the production server to standby server.
I have a question: in the document SAP Oracle Standby Database, tells me I should change the tnsnames.ora production server pointing to an additional entry disaster recovery server. The tnsnames.ora file must have two entries??? corresponding to a production server and another to the disaster recovery server??
In several links of oracle tells me I should configure listener.ora disaster recovery server that is true??
Guys my question is: where should I change my listener.ora and tnsnames.ora files?
Please clear my doubt.
Best regards,
Desiree

Hi Desiree,
The entry in your TNSNAMES.ORA is a nothing but a tns service, when you define archive log destination it will point to a service. This service's host name will be resolved in your tnsnsmaes.ora file.
Below is the eg of an entry in pfile:
*.log_archive_dest_2='SERVICE=<service_name> ARCH OPTIONAL'
Below is the entry in your tnsnames.ora file
<service_name>.WORLD=
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS =
 (COMMUNITY = SAP.WORLD)
 (PROTOCOL = TCP)
 (HOST = <DR_HOST>)
 (PORT = 1527)
 (CONNECT_DATA =
 (SID = <DB_SID>)
 (GLOBAL_NAME = <DB_SID>.WORLD)
So, your tnsnames.ora will have one entry for your host and the other for the DR host, i.e two entries.
Listener entry for the convenience when there is a switch over.
Regards,
Bala

This makes no sense. You don't configure a listener nor a tnsnames.ora "in a database".   I hope this is just a language issue and not reflective of a fundamental misunderstanding of how tns works.

Trouble with listener.ora and tnsnames.ora

I can't get the listener running.
Trying to start the listener results in the following message:

I suspect i have a configuration error in listener.ora or tnsnames.ora, but I'm stumped at this point.
Can anyone help?
Much appreciated.

Assume you've got $ORACLE_HOME
We'd end run listener problems by setting/exporting TNS_ADMIN and putting tnsnames.ora and listener.ora files in a standard place ( ../dbs for our site) rather than Oracle's defaults.
We'd also found that there is a parsing problem of the tnsnames.ora file by 9.2 ( its in AIX and MAC versions at least). Placing the entire description section on a single line consistently resolved problem.
Opening a Tar on that one.
So Now we're accessing Dbs based on mac and AIX from Multiple MAC and AIX remote sites with SQLPLUS and thin clients.

Listener.ora file

Hi,
How do I update the listener.ora file to add my listener names hrms for my database with the same name. Current it is
