Re: Multiple Listeners
Here are my current findings Auto Registration : === 1. Auto Registration takes place with default listener when local_listener=(ADDRESS=(PROTOCOL=TCP)HOST=lightening)(PORT=1526)) When the above line was NOT present in init.ora of the database (db7) for whcih the second listener is configured, the database Auto registered with the old listener (v816, PORT=1521) too. So, that I could connect to the database through both listeners. 2. Auto Registration does NOT take place with default listener when local_listener=(ADDRESS=(PROTOCOL=TCP)HOST=lightening)(PORT=1526)) When the above line was present in init.ora of the database (db7) for whcih the second listener is configured, the database Auto registered with the new listener. So, now I could connect to the database through the new listener only! Multiple Listeners : 1. Is it possible to have single listener? You can use the 'higher' version of the listener for all databases running on = higher version, unless you need multiple listeners for other reasons Net8 Admin Guide should have enough information. So, using signel v817 listener for v817 as well as v816 databases was possible. 2. What's involved in configuring multiple listeners? There are metalink docs explaining it in details, But in short : They have to be of different names. Explicit name needs to be used for non default (name other than LISTENER) listeners while using lsnrctl command. They need to be listening on different ports. The KEY value for IPC needs to be different in each listener.ora. 3. Why I decided to run single listener in the end? When I was running two listeners, each was listening on different ports. Initially, I had only one listener at PORT=1521. So all my client side configuration in tnsnames.ora were pointing to PORT=1521. Now with this second listener listening at PORT=1526, I would have needed to change all of my client side configuration. (We are not using Names Server currently.)

Re: Multiple Listeners
There has been much discussion regarding single or multiple listeners and there seems to be a split between those who advocate one method over the other. I am currently working at a site with a large number of systems/databases. They are well organised and one of the standards that is in place is to have a listener per database with the same name as the database. The lowest port will be 1526 to avoid any issues with auto registration on port 1521. The whole concept works very well in my experience; the small overhead on the server is outweighed by the ability to stop a listener individually without affecting any other service. John

Re: Multiple Listeners
On most servers I have only one database on the node. Where I do have multiple databases, I have seperate ORACLE_HOMEs. Where I have seperate ORACLE_HOMEs, I have seperate Listeners. There's really not much of an effort in managing multiple listeners -- after all you have to issue a seperate sqlplus command for each database [and also from a seperate ORACLE_HOME each time !] , you can also issue a seperate lsnrctl start listenername command. I could be running 8.1.7.2, 8.1.7.3 and 9.2.0.1 on the same box. When applying a patchset to upgrade to 8.1.7.3 or 8.1.7.4 for one database, I do not want to have to stop access to the other databases. Therefore, each database has it's own listener. Also, try _not_ to use 1521 as the listener port so that no database auto-registers with a listener.

RE: Multiple Listeners
Rachna, Do yourself a favor - use the most recent listener for all databases. Have only one listener running on a machine and use that for all databases on that machine. In your case, use the 817 listener. In the long run, it will be much easier and less confusing. Hope this helps.

RE: Multiple Listeners
I respectfully disagree. I am currently working on a Sun 4500 cluster with Veritas. The cluster services each maintain their own nic/ip, that's 1 per instance. Obviously, each instance also has its own listener. This has been very easy to implement and not at all confusing. It also avoids things like where you can't use a 8.0.5+ listener for 8.0.4- instances. Each SID has its own listener at its own version level. I would suggest coming up with a good standard for determining ports and such however. For instance, I use 15 concatenated with the last 2 digits of the assigned IP. Before walking into the cluster world, I would have agreed with Tom. Of course now I have seperate HOMEs for each instance too.

Re: Multiple Listeners
It is better to have a single Listener per server, unless you have multiple
servers that use high availability fail over between the servers. The
single listener should be the most recent one on the server. It is
backwards compatible with Oracle8i versions and Oracle7 databases. There
is no need to run multiple listeners on the same server, especially when
the versions are just one release off from each other (e.g. 8.1.6 and
8.1.7). A single listener and a single Intelligent Agent should be all
that is needed. It may be clever to see if multiple listeners can run, but
even Oracle will tell you that running multiple listeners is worse than
foolish.:) In addition to changing the Oracle Home, the LD_LIBRARY_PATH or
LIBPATH would have to be changed as well to match the libraries to the
correct version of the listener.
Trust me, you only need one version of the Listener up. I have three
versions of Oracle on a server: Oracle7, Oracle8i v8.1.7 and Oracle9i
v9.2.0. I use the Oracle9i listener and agent on the servers. It allows
seamless connections to all the databases.

Thanks for the inputs.
This is how I did it.
1. There are two listener.ora files
/opt/app/oracle/product/816/listener.ora : FILE816
/opt/app/oracle/product/817/listener.ora : FILE817
FILE817 is a copy of FILE816
2. Entries for db7 are removed from FILE816
FILE816 listner name is left unchanged as LISTENER
FILE816 entry for IPC was left unchanged :
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
FILE816 entry for PORT was left unchanged :
(ADDRESS = (PROTOCOL = TCP)(HOST = lightening)(PORT = 1521))
3. Entries for db6 are removed from FILE817 and ORACLE_HOME path changes
are
made
FILE817 listner name was changed to LISTENER_817
FILE817 entry for IPC was changed as :
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_817))
ORACLE_HOME path changes were made to FILE817
FILE817 entry for PORT was changed as :
(ADDRESS = (PROTOCOL = TCP)(HOST = lightening)(PORT = 1526))
4. To use 816 listener
ORACLE_HOME=$/opt/app/oracle/product/816
cd $ORACLE_HOME/network/admin
$ORACLE_HOME/bin/lsnrctl stop listener
$ORACLE_HOME/bin/lsnrctl start listener
$ORACLE_HOME/bin/lsnrctl status listener
9. To use 817 listener
ORACLE_HOME=$/opt/app/oracle/product/817
cd $ORACLE_HOME/network/admin
$ORACLE_HOME/bin/lsnrctl stop listener_817
$ORACLE_HOME/bin/lsnrctl start listener_817
$ORACLE_HOME/bin/lsnrctl status listener_817
And I think I am having
a. two separate Listeners
b. for two different databases
c. in different version (having different ORACLE_HOME)
d. listening at different ports
Am I correct or there is some mistake / improvement?
Thanks for the inputs.

However, due to experience with past bugs (and who knows when similar problems may appear in the future) and as you concede, running high availability fail over services, I would disagree with the assertion that multiple listeners are worse than foolish. A single listener is a single point of failure across multiple instances, eliminating that is not foolish, and there are other reasons one might want to run multiple listeners. What about extproc (if you need it for some reason). Oracle itself _requires_ 3 listeners for the apps the last time I checked (1 for the db, 2 for external program calls). To analyze network traffic, it is sometimes useful to be able to isolate particular port traffic. Multiple listeners allow for this kind of work too. So, while only 1 may be all that is necessary, there is no real reason, IMHO, that multiple listeners are inherently a bad practice.

RE: Multiple Listeners
-Original Message- but even Oracle will tell you that running multiple listeners is worse than foolish.:) Trust me, you only need one version of the Listener up. From O'Reilly's Oracle Net8 Configuration and Troubleshooting book, pages 70 - 71, under the sub-topic Why Use Multiple Listeners?: Even though one listener may be all you need, there are some management advantages to using more than one: redundancy and separation of environments. Two listeners can be used to provide redundancy in case one fails. Such a configuration not only protects you from the failure of one listener, it also enables you to more easily make changes that require a listener to be restarted. ... Separation of environments is another reason to use multiple listeners. If you have two databases running on a server, you may not want any part of those two database environments intertwined. That way, if you need to restart the listener for one database, you don't affect users of the other. ... End of quote. I might add, if you have multiple versions of Oracle running on a box and need to patch a version in such a way that requires a complete relinking of that version, you can stop only the processes associated with that version. The decision to run multiple listeners was not my decision to make here. But having worked in this environment for a while, I can say that it has never been a problem. -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Stephen Lee INET: [EMAIL PROTECTED] Fat City Network Services-- 858-538-5051 http://www.fatcity.com San Diego, California-- Mailing list and web hosting services - To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).

RE: Multiple Listeners
Okay, I will concede the point. Sometimes having multiple listeners can be a good thing. Although running older versions of the listener may not be. But you pay your money and you take your chances. Thank you for those who cited published sources. Please remember: what an Oracle analyst will tell you on the phone and what is printed in the documentation do not always match. If you have ever had a torturous TAR then you know what I mean.

RE: Multiple Listeners
Congratulations !!
Now one more point---
If one uses default listener name (listener) and default port (1521),
databases (8i,+) will auto register with this listener first.
Either do not use default names and ports, or make sure that you set your
init.ora parameters (service_names?) correctly to register them with the
listener you wanted those databases to use.
I think there is Note on Metalink discussing this issue. I forget the note
number at the moment

Thanks for the inputs.
This is how I did it.
1. There are two listener.ora files
/opt/app/oracle/product/816/listener.ora : FILE816
/opt/app/oracle/product/817/listener.ora : FILE817
FILE817 is a copy of FILE816
2. Entries for db7 are removed from FILE816
FILE816 listner name is left unchanged as LISTENER
FILE816 entry for IPC was left unchanged :
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
FILE816 entry for PORT was left unchanged :
(ADDRESS = (PROTOCOL = TCP)(HOST = lightening)(PORT = 1521))
3. Entries for db6 are removed from FILE817 and ORACLE_HOME path changes are
made
FILE817 listner name was changed to LISTENER_817
FILE817 entry for IPC was changed as :
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_817))
ORACLE_HOME path changes were made to FILE817
FILE817 entry for PORT was changed as :
(ADDRESS = (PROTOCOL = TCP)(HOST = lightening)(PORT = 1526))
4. To use 816 listener
ORACLE_HOME=$/opt/app/oracle/product/816
cd $ORACLE_HOME/network/admin
$ORACLE_HOME/bin/lsnrctl stop listener
$ORACLE_HOME/bin/lsnrctl start listener
$ORACLE_HOME/bin/lsnrctl status listener
9. To use 817 listener
ORACLE_HOME=$/opt/app/oracle/product/817
cd $ORACLE_HOME/network/admin
$ORACLE_HOME/bin/lsnrctl stop listener_817
$ORACLE_HOME/bin/lsnrctl start listener_817
$ORACLE_HOME/bin/lsnrctl status listener_817
And I think I am having
a. two separate Listeners
b. for two different databases
c. in different version (having different ORACLE_HOME)
d. listening at different ports
Am I correct or there is some mistake / improvement?
Thanks for the inputs.

It works fine. Here is an example of some commands to put into a general
Oracle startup script.
export ORACLE_BASE=/oracle/app/oracle
export LOGFILE=${ORACLE_BASE}/log/ora-startup.log
exec $LOGFILE 21
touch $LOGFILE
chmod a+r $LOGFILE
print \nStarting ora-startup

# Automatically export all variables
set -a
# Start the databases
$ORACLE_BASE/admin/dbascripts/init.d/dbstart
# Start the listeners
export ORACLE_HOME=$ORACLE_BASE/product/9.2.0
$ORACLE_HOME/bin/lsnrctl start LIST_V920
export ORACLE_HOME=$ORACLE_BASE/product/9.0.1
$ORACLE_HOME/bin/lsnrctl start LIST_V901
#Start the listeners
export ORACLE_HOME=$ORACLE_BASE/product/8.1.7

$ORACLE_HOME/bin/lsnrctl start LIST_V817
$ORACLE_HOME/bin/lsnrctl start LIST_V817_2

We did have a problem trying to get one listener in 8.1.6 to listed for 8.0.x and 7.3.x databases and WWS discovered that a bug they thought was fixed in 8i was not fixed for Compaq. We're now looking at OID. Any horror/success stories out there? Stephen [EMAIL PROTECTED] 07/16/01 04:47PM Alex, This gets down to the amount of trust your damagement has in you. If theyare more tempted to listen to outside assertions that you have already heard,then it's time to move on because your being treated like a trained monkey. Mymanagement does ask questions on this type of subject when they've heardsomething new outside. It's normally just tossed in my direction as a "Hey Iheard that these folks are doing this. What do you think?". In which case Inormally find out what their doing why and what Oracle says about it as well. If it does not make sense, it ends up in the round file there is no morediscussion. It also helps to have management types who have some knowledge ofthe technology. The result is less of the problem you state. From a listener perspective, there is only one absolutely good reason thatI've found to run more than one listener per node that is that after you pass10 DB's in one listener it appears to run out of memory won't listen for theothers.

RE: Multiple Listeners
Mladen, I can think of numerous reasons to have multiple listeners. For example, imagine a server with several databases where you sometimes wanted to restrict outside access on just one database. Meanwhile still allowing local users on that server to access that particular database. In this case restricted mode wouldn't work, and downing the listener would restrict remote access to all the databases. With multiple listeners you could shutdown the listener for just that database. Outside users would then be unable to connect, but local users would still be able to work. The other databases would continue as usual... Another example, Veritas Cluster, is the reason I use multiple listeners. You need to be able to failover the listener for just one database, not all of them!

Re:RE: Multiple Listeners
ED, OK, looks like you've got 2 or more servers, each supporting a single DB or are you running parallel server? I'll assume the later since that would make more sense. Therefore, set up each listener to listen for requests on it's hostname and port 1521 which is just about the standard. I'd give each listener a specific name like 'listener_node_name' so that you can have everything in one file and use only what is needed. Kinda of like Alan suggested, but with different hostnames. I think he was thinking on multiple listeners on one host, not multiple listeners on multiple hosts. Dick Goulet Reply Separator Author: Edward W.

RE: Multiple Listeners
However, to answer the question, you need to name the listeners something other then listener and you need to have them listening on different ports. When you use the lsnrctl command you have to reference the listener you are dealing with. There are reasons to have multiple listeners. For example, when running HP ServiceGuard I have setup the databases to be able to fail separately so they each have their own listener that fails with the database. I needed it with Trusted Oracle as well, but I believe that is case dependant. On listened for stuff coming from the secret side and the other from the other side. -Original Message- Sent: Monday, July 16, 2001 3:56 PM To: Multiple recipients of list ORACLE-L Edward, One must ask, what benefit do you perceive you will obtain from having multiple listeners? The listener is only there to hear the end applications request for database service and pass them along to the appropriate dedicated server or dispatcher as required. Then it goes off to do other things. We have one HP with 9 different instances, one listener. Works fine all day. Dick Goulet Reply Separator Author: Edward W.

RE: Multiple Listeners
If you are using external procedures, the listener for them should be different as well. The external procedures run under the authority of the user which started the listener that has the sid list entry for them. If you place the entry in the main listener and that listener is initialized by oracle, the external procedures run with the authority of the oracle OS user. Having a different listener which can be started by a less privileged account allows the external procedures to run with less authority.

Re:RE: Multiple Listeners
Alex, This gets down to the amount of trust your damagement has in you. If they are more tempted to listen to outside assertions that you have already heard, then it's time to move on because your being treated like a trained monkey. My management does ask questions on this type of subject when they've heard something new outside. It's normally just tossed in my direction as a Hey I heard that these folks are doing this. What do you think?. In which case I normally find out what their doing why and what Oracle says about it as well. If it does not make sense, it ends up in the round file there is no more discussion. It also helps to have management types who have some knowledge of the technology. The result is less of the problem you state. From a listener perspective, there is only one absolutely good reason that I've found to run more than one listener per node that is that after you pass 10 DB's in one listener it appears to run out of memory won't listen for the others. I did find a bug on Metalink on the subject, but it was suppose to have been fixed in 8.0.6 though I've not verified that.
