11.2.0.3 database listener

Hi All,
Is it true that in 11.2.0.3 listener you can not manually edit it anymore? to add database services?
It is mandatory to use Net Manager? Or even Net Maganer wil not be used?
I have done this in 10g and 11gR1. I am not used to using Net Manager in adding database service in the listener.
What I usually do is edit the listener.ora and manually copy/create entries. And my listener works fine.
Kindly help.....
Thanks a lot,
Kinz

Wow I did not know this. So since the start of 8i you do not need to register a database anymore in the listener.ora? Incorrect. Read documentation (which you never do)
What happen if you have lots of database versions in the server? like 8i, 9i, 10g, 11g, 11.2.0.3Read documentation wrt to the downwards compatibiliity of sqlnet.
Will it be able to handle the no-add db service in the listener? How will the listener of 11.2.0.3 knows that there exist 8i,9i,10g, 11R1 db when they have different Oracle Homes?Again, read documentation.
So i will not have to run NETCA? So I will not see anymore listener.ora file located at OracleHome Network Admin forlder?Nonsense. Static registration is still required for most Oracle versions, in order to be able to use OEM/Grid control/dbcontrol.
Is this for windows only or even linux?As you could have known by now, Oracle works the same across all platforms on which it is available.

Unable to auto start database/listener/EM on Oracle Enterprise Linux 5

All Experts
I have install oracle 11g on Oracle Enterprize Linux 5 successfully.
done all post installating steps, but when i restart server oracle listener/database/EM not automatically start.
Please guide what is wron (server dbora error: /bin/sh: :No such file or directory).
1. Log in as the root user
2. Edit the oratab file (SID=Y)
3. Create a file called dbora
4.Run chmod and chgrp on the dbor file
# chgrp dba dbora
# chmod 750 dbora
6.Creat symbolic links to the dbora script
# ln -s /etc/init.d/dbora /etc/rc.d/rc0.d/K01dbora
# ln -s /etc/init.d/dbora /etc/rc.d/rc3.d/S99dbora
# ln -s /etc/init.d/dbora /etc/rc.d/rc5.d/S99dbora
7. add service
# chkconfig --add dbora
# chkconfig –list dbora
0:off 1:off 2:off 3:on 4:off 5:on 6:off
# ls -l /etc/rc*.d/*dbora

'stop')
su - $ORACLE -c "$ORACLE_HOME/bin/dbshut $ORACLE_HOME"
echo "usage: $0 {start|stop}"
exit
esac
exit

does the script work when you log on to your freshly started system, logon as root and execute /etc/init.d/dbora start?
the script does not have to have group membership of the dba group.
also, do not create symlinks yourself.
by adding the service using chkconfig the script is started and stopped as indicated by chkconfig --list, no need to do additional steps like creating symlinks.

Standby database(11g) was still in sync after stopping the primary and standby database listener.

Hello !!!
I have noticed that my standby database(11g) was still in sync after stopping the primary and standby database listener.
If this is the case then how log is transferring from primary to standby ? it is not using listener service ? kindly clarify

Read this Metalink Note:407040.1

What is default database listener port number

Running emca script requested for database listener port number. Where do I get this information from.

If the port number is not specified in listener.ora,
you may get different values with 10gR1 such as 1509,
1525, 1525 or 1531 (on Windows XP SP2).
I guess this depends also on whether the TCP/IP port
1521 is really released or notI have seen what you have described above when port 1521 was in use by another process. If the port is not in use, I have not seen any thing other then 1521 assigned when the listener was created either during installation or afterwards using Net Assistant.

Did you try a tnsping to see if it can provide name resolution? Can you connect to the database using the connect string service name such as sys@pussdb? These would indicate whether the database has been properly defined in your databse names resolution method (e.g. tnsnames).

Hi Hsawwan,
Thanks for your help. I'm totally confused of the useage of the addlnctl.sh below. See, when I type sh addlnctl.sh stop ,the system show the useage of the shell script. it's seems I need to put the listener name after sh addlnctl.sh stop. As I installed the demo in my PC, the database name known as VIS, I don't know I should put the listener name as ORACLE_VIS or VIS only. I have tired the sh addlnctl.sh stop ORACLE_VIS, the script returned the status 1 and log message in my priori update, but when I tried the sh addlnctl.sh stop VIS, the script returned the status 0 and completed fast. Could you tell me which one I should use for the addlnctl.sh ? ORACLE_VIS or VIS only?
oravis@vostro VIS_vostro$ pwd
/u01/oracle/ora/visdb/9.2.0/appsutil/scripts/VIS_vostro

Automating Database, Listener, Entr. Manager Startup & Shutdown in OEL5

Hi All,
bq. I am a quite newbie to Linux, I have installed Oracle 11g on Oracle Enterprise Linux 5 on VMWare by following [this article|http://www.oracle.com/technology/pub/articles/smiley-11gr1-install.html] everything went fine. But my problem is I need to explicitly start and shutdown database, listener & EM. Is there is anyway to automate this, start services on linux startup and stop them during linux shutdown. \\ If any linux script or links/articles available for this requirement, it will be very helpful to me?
Thanks,
Sumanth

I am following the below steps
1) edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'.
orcl:/u01/app/oracle/product/11.1.0:Y
2) create a file called "/etc/init.d/dbora" as the root user, containing the following.
#!/bin/sh
# chkconfig: 345 99 10
# description: Oracle auto start-stop script.
# Set ORA_HOME to be equivalent to the $ORACLE_HOME
# from which you wish to execute dbstart and dbshut;
# Set ORA_OWNER to the user id of the owner of the

ORA_HOME=/u01/app/oracle/product/10.2.0/db_1
#ORA_HOME=/u01/app/oracle/product/11.1.0/db_1
ORA_OWNER=oracle
if [ ! -f $ORA_HOME/bin/dbstart ]
then
    echo "Oracle startup: cannot start"
    exit
fi
case "$1" in
    'start')
        # Start the Oracle databases:
        # The following command assumes that the oracle login
        # will not prompt the user for any values
        su - $ORA_OWNER -c "$ORA_HOME/bin/dbstart $ORA_HOME"
    'stop')
        # Stop the Oracle databases:
        # The following command assumes that the oracle login
        # will not prompt the user for any values
        su - $ORA_OWNER -c "$ORA_HOME/bin/dbshut $ORA_HOME"
esac3) set the privileges to 750.
chmod 750 /etc/init.d/dbora
4) Associate the dbora service with the appropriate run levels and set it to auto-start using the following command.
chkconfig --level 345 dbora on
if am doing anything wrong do let me know
thanks

Suppress database/listener/agent unreachable if host unavailable

Hi,
When a host becomes unavailable due to network issues we receive a deluge of agent/database/listener/host unreachable notifications. Is there a clean way to make sure that when a host is unreachable via ping for example other unreachable target notifications are suppressed?
Thanks for any help in advance

JMS as database listener

Hi, good day to you.
I would like to know how to implement JMS as database listener, so that any CRUD process to the database will send a notification to JMS listener.
Any tutorial or articles?
Thanks.

What you call a "database listener" is, in the database world, called a "trigger".
Check the documentation for your database to see if it supports triggers (not all of them do) and what languages they can be written in.

Weblogic Connection pool active even database listener down

Just wanted to check if sometime noticed this.
Today.. In production our Database listener was down and connection pools in weblogic were still working fine. But, when tried making a explicit call to DB it throws exception "The Network Adapter could not establish the connection"..
Couple of days back our production database was restarted. Sill weblogic connection pool was active without restart.
Any info. is appreciate..
Thanks

Hi Jung,
There is no timeout current that you can set on the connection pool. It will
be in a future release of WebLogic

Any major differences of exadata database, listener, processes than regular RAC environment?

I would like to ask for any input regarding any major differences of exadata database, listener, processes than regular RAC environment.
I know now the exadata not only have SCAN listener, but a lot other listeners. can expert here provide more details?
Thanks

We will use zfs to do backups, is that possible for the initiband listener to communicate with ZFS? where I can find documents for zfs?
The SDP (Infiniband) Listener is for client connections connecting to the database on Exadata over the SDP protocol on the Infiniband network. You should use the Infiniband network to connect the ZFS to Exadata and mount the ZFS shares to the Exadata compute nodes using DNFS; but this doesn't use the SDP listener because there is no database connection originating from the ZFS you are just backing up your databases to it. See the "Oracle ZFS Storage: FAQ: Exadata RMAN Backup with The Oracle ZFS Storage Appliance (Doc ID 1354980.1)" MOS note for good information and references regarding backing up from Exadata to ZFS.
Plus how do I know we have exalogic? I dont think we have one, but is there a way to check to be sure?
Exalogic is another of Oracle's engineered systems. It contains integrated compute, network and storage - similar to Exadata - but is used for running application environments, specifically for fusion middleware (e.g. Weblogic) applications, instead of databases. It uses a ZFS storage appliance for the storage, as opposed to the storage cells on Exadata, and for virtualized environments uses the Exalogic Elastic Cloud software. You would know if you have one.
So basically after oracle engineer installed onecommand and created sample database, as oracle dba, we can dbca to create a database just like regular RAC environment? There is nothing specific on exadata perspective?
Yes... Oracle on Exadata is still the same RDBMS - same Oracle Enterprise edition with the RAC option. The Exadata difference comes with the hardware integration and the storage cell software... the database software is the same.
Another question is do I have to configure exadata specific parameters in order for all those features of smart scan, storage index, comrpession, etc work?
Some Exadata features are mostly "black box" and work without any configuration others may take some configuration or tuning to take advantage of. For example, storage indexes are created dynamically on the storage cells... there is not much you can do to control them. For smart scans you need full table/index scans with direct path reads. So you need to tune for direct path reads. HCC requires setting up your tables/partitions to compress at one of the HCC compression levels and using direct path loads.

MDB and Database - Listener port stops working

Hi,
I have created an MDB which does the following when a message is received from the queue.
1. Store message in database
2. do some processing
At step 1, if there is any issue with the database connection (e.g. database is not available etc), I rollback transaction. My idea is to leave the message on queue for now and retry it again after some time unless the database is back again. "Maximum retries" of the listener port is set to N but since there is no retry interval available, all N retries are done in a flash and my listener port stops working. I cannot use backout mechanism as I have to wait for the database to be back again. What are my options?

a simple JDBC rollback won't do it.

Can I change the database Listener name in 11.5.10.2

Hi Hussen
Is it possible to change the Listener name and port on database node. My Application is of 4 node env. 2 rac database nodes 2 shared application tier nodes.
My requirement is to change the Database node listener name and port.
Thanks

Reddy,
It is possible -- Please see (How to change the hostname and/or port of the Database Tier using AutoConfig [ID 338003.1]) for details.
However, it is always recommended you have the ports on the application/database tier nodes within the same port pool -- See (How To change the Port Pool in the E-Business Suite 11i [ID 414439.1]).
Thanks,
Hussein
