10g listener question

Hi
All,
First question
When I do some minor modification in tnsnames.ora. Do I Need to stop and start listener again.
Second question
And If I want to stop and start listener Do I need to stop all the databases before I can stop and start listener ? (9i and 10g)
Thanks,
Vishal

When I do some minor modification in tnsnames.ora. Do I Need to stop and start listener again.No, tnsnames.ora is totally independant to the listener.
And If I want to stop and start listener Do I need to stop all the databases before I can stop and start listener ? (9i and 10g)No, the listener is used only to connect new client to the server, once the connection is done, listener is not used anymore for that connection.
Note you can reload instead of stop and start the listener.

Starting 10g listener

Hi,
I am upgrading a database to 10g manually and before I issue the startup upgrade command, I believe I have to start the 10g listener. The script I always use for the db-tier listener is under $ORACLE_HOME/appsutil /script directory but my new install of 10g software has not got any appsutil directory. So, my questions is how do I start the 10g listener?
Thanks

Once you are done with the upgrade, you will need to implement and run AutoConfig on the new Database home for the purpose of creating appsutil directory. For more details, check "Copy AutoConfig to the RDBMS ORACLE_HOME" step of Note: 165195.1 - Using AutoConfig to Manage System Configurations with Oracle Applications 11i

9i and 10g Listener in SUN box How do i stop .while applying the patch.

Hi,
Sun box running - I am having
1. oracle_home 9i Version (database's are running)
My team installed 10g Version 10.2.0.1 in Oralce_home1 there were no database are running in 10g, Now We plan to upgrade into 10.2.0.4 in oracle_home1 while applying patch its asking to stop the listener process.
Is it mean to stop 91 listener or 10g listener?
I had checked the running process in my server using grep -ef
it show all process 9i database's and i find this home1/oracle/product/1020/bin tnslsnr LISTERNER -Inherit. How do i stop ? after applying the patch how do i start?
Is it require down time?
Thanks in advance.

Hi
When i check the lsnrctl status it is showing the error , How do i resolve it?
In sun box:

EM12c Oracle Database Plug-In 12.1.0.7 update now shows 10g listener as down when it's not

EM 12.1.0.4 with Oracle Database Plug-in 12.1.0.7
Monitored database and listener: 10.2.0.4
Our EM12c monitors 12.1,11.2 and 10.2 databases and listeners. All monitored targets are up and running.
I updated Oracle Database Plug-in from 12.1.0.6 to 12.1.0.7 and now the only 10g listener that I have shows as down.
The listener on the server is up and running.
The monitoring configuration is right.
I removed this target and re-added it, but it came back as down.
It's a little disconcerting to have a listener show as down since it's a production box, but nothing I do corrects the problem.
Any insights or suggestions are appreciated.
Sherrie

Hi Sherrie,
In most cases we have this issue due to monitoring configuration , I know you mentioned that you have checked on it but still I would recommend to just re-confirm on below steps
1. Go to
    EM Console -> Targets -> Listener -> Listener Home page -> Target Setup -> Monitoring Configuration
2. Get the details
      Listener Name
      Listener.ora Directory
      Machine Name
      Oracle Home
      TCP Port Numbe
3. Go to the server where this listener is running
   Check to see if the listener is up
       ps -ef | grep tns
4. Next run
       $ORACLE_HOME/bin/lsnrctl status
   From this outpuy verify details in (1)
      Listener Name   <======= Alias
      Listener.ora Directory <=== Listener Parameter File ie the directory
      Machine Name <======= HOST=
      Oracle Home<========== This is where tnslsnr is started from
      TCP Port Number <====== PORT=
5. Makes sure that all the details matches in (4) and (2)
If above is fine then I would recommend to go through the troubleshooting steps as per below doc , they are valid for listener status down too and should give a further insight on the root cause of the issue

Listen oracle 8i instances with a 10g listener

Hi,
Does someone try to listen oracle 8i instances (8.1.7.4) with 10g listener (10.2.0.3)
thanks a lot.
David

Hi, humhum
I created my listener on 10g and it doesnt see the 8i instances. So, I added manually an entry in listener.ora for 8i instance.
Have a look :
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = F:\10g\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
(SID_DESC =
(SID_NAME = LEGAL)
(ORACLE_HOME = F:\8i\oracle\ora81)
(PROGRAM = LEGAL)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = frcdgorcld1.eur.galderma.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
But from a client connection, I receive the following error message :
ERROR - ORA-12518: TNS:listener could not hand off client connection
Thanks for your help

Oracle 10g listener standard

Hi all,
I am trying to define Oracle 10g listener standard in my organization.
We have 60 Oracle 9i databases in an AIX node. We are planning to upgrade these database to 10g. During upgrade we want to configure the listeners according to our standard.
Now we are not using dynamic registration for Oracle 9i databases. So there are 60 seperate listeners that always try to establish connections to the database even if the database is not up. This leads to server performance problems when the applications overload the server with connection attempts when there are hundreds of processes waiting to connect.
After upgrade, we want to make all databases register with a listener for performance problems. But one listener per node can be too risky, maybe we can register a database with more than one listener.
Also, there are some reasons for shutting the listener down:
1. Cold backup
2. Apply patches
If we use only one listener per node, for cold backup we would shut down the listener and then no clients would connect to the databases.
After these explanation, I am wondering if we can mix both reducing the number of the listeners for each node and using load balance for all databases.
Do you hane any ideas, suggestions?
Thanks,
Fatma

With Oracle 10g and RMAN there is no longer any reason to be doing cold backups.
I'd run one listener per node. If this is too risky than a single database instance is also too risky and you should be investigating other high-availabilty solutions. RAC isn't always the answer.
Connection manager might also be useful in your environment.
Cheers,
Colin

10g listener cannot start after install 11g

Hi,
I install 11g R2 into one of 10g windows 2003 server, but I did not perform upgrade, I want the 11g coexists with 10g.
But after I install 11g and create a new 11g instance, I found that the listener cannot be started, until I change the environment variable ORACLE_HOME
of windows to 11g home directory.
But when I reboot my server, I found that the old 10g listener cannot be started,
the services cannot be started and if I try to start the listener in command "lsnrctl start", error TNS-12560: TNS:protocol adapter error prompt.
So I changed the ORACLE_HOME environment variable to 10g home directory again and the listener can be started.
And when I want to start 11g listener, I will have to change again the ORACLE_HOME environment variable to 11g home directory.
Is this a normal behaviour to have 11g and 10g co-exists in one server?
Thanks
Vincent

Vincentonly 1 listener is needed on any DB Server & the listener should be for the highest version of Oracle DB Server

10G listener over eager?

We have both 9i and 10g DB's on a Sun host. We want to have the 9i listener accept connect requests for 9i only and the 10g listener for 10g only. Listener.ora files have been configured to support this. The listeners run on different ports and can be started/stopped seperately.
The 9i listener accepts requests for it's databases but not the 10G (as you would expect).
The weird thing is : When we start the 10g listener, and do 'lsnrctl services' is lists it's one and only 10g DB. Good. After waiting a few minutes, running the same command again ALSO lists the 9i databases. A connect sql*net to the 10g port for a 9i database gets connected!!
Is this a 'feature' we can turn off?
Hope the description is clear enough,
thanks in advance,
Vin.

Can someone running 9i & 10G on the same Solaris host, using seperate 9i and 10g listeners please check and let me know if their 10g listener lists (lsnrctl services) the 9i databases even though they are NOT configured in the 10G listener.ora?
TIA,
Vin

Listener question

Hello All,
I have oracle 10g and 9i running on Solaris 9. The 9i was installed after 10g was installed. Now I cannot get 9i listner to work properly and getting following error messages and not sure how to resolve it.
TNS-12542: TNS:address already in use
TNS-12560: TNS:protocol adapter error
TNS-00512: Address already in use
Solaris Error: 125: Address already in use
12618, 00000, "TNS:versions are incompatible"
Any pointers and help will be appreciated.
Thanks

You may not need to run the two listeners. Register the 9i Database with the 10g Listener and restart the listener.
Or
As mentioned already check the file $ORACLE_HOME/network/admin/Listener.ora for both 10g and 9i. Change the default port for one of the two homes and restart the listener ouy the home you changed.
Note: It is better to change the latest Listener that no TNS connections have already been configured to use in order not to go reconfiguring tnsnames.ora files. So the choice of which home's listener port to change should be make carefully.

Discoverer 10G Plus Questions

Hi
We're in the process of upgrading from Discoverer 4 (APPS EUL) to 10G. We're doing away with the Desktop client. Most users will be given access to Discoverer Viewer and other users will be given access to Plus. We have recently upgraded or DEV instance and there are a few "questions" (i.e. gripes) that users have come back to me with:
1) Do all reports have to be stored on the database to allow them to be accessed by Plus or Viewer? Can only the 10G client version open files from a local hardrive or shared network drive?
2) Can only one report be open at any given time with Plus or Viewer? In client it is possible to have 2 reports open at the same time to facilitate easier comparisons.
3) NULL values are still showing the word "NULL" even though in Tools Options we have set it to show blank, existing reports are still using the NULL value.
I'd very much appreciate feedback on any of the 3 points above.
Thanks.
Paul.

Hi paul,
Its a good idea to upgrade from 4i to 10g 4i is no more used by many and their are some issues or bugs with it.The latest version is 11g which has been released 1 week back.If not go with 10g version available.
1) Do all reports have to be stored on the database to allow them to be accessed by Plus or Viewer? Can only the 10G client version open files from a local hardrive or shared network drive?Yes they have to stored in the database so any ened user can access them from plus or viewer.
Can only one report be open at any given time with Plus or Viewer? In client it is possible to have 2 reports open at the same time to facilitate easier comparisons.Yes,if the reports are registered as different reports and if the end user has access to both the reports thn he can open and compare it OR if both reports are in same workbook as different sheets than its easy to view or compare.
NULL values are still showing the word "NULL" even though in Tools Options we have set it to show blank, existing reports are still using the NULL value.It should show blank,might be some problem.In discoverer 10g i think you will not find this issues.
Hope this helps you.
Best Wishes,
kranthi.

10g memory question on windows 2003 64-bit

oracle 10.2.0.4
windows server 2003 sp2 64-bit
We have a 10g database running on a windows 2003 64-bit with 32GB memory. We set the sga max and target to 10GB and cache to 5GB.
When I look at the task manager, I see there is only 1GB of free memory left. We only have the database running on this server. I would expect a lot more free memory on this server. What would account for the difference? thx
32GB - 10GB (db) - 5GB (cache) - 6.5GB (20% OS) = 10G

10g Listener

Hi all.
I have win xp computer on which i instaled 10g RDBMS and then patched it to 10.2.0.3.0 .
Then I tryed to create the database with[b] dbca , creation stopped at 2% with :
ORA-12560 : TNS: Protocol adapter error, so i started netca to create the listener and got the folowing message :

Hey Adnan.
I forgot :-( to mention that when i was installing 10g software, i encountered a problem described here (maybe this was reason for listener configuration failures?)
Re: error in Oracle 10g Installation windows 2000 advance server
but i proceeded with instalation , and of course i patched it later.
I have functionality of that software that i used like Oracle 10g client for connections through sqlplus or toad, but when i tryed to create database i was start to get those errors above , for which i think was responsible my primary DHCP adapter.
Now i deinstalled Oracle software and cofigured that adapter with static IP adress.
After that i have started with instalation of software again and instalation prerequestes were checked without errros.
So when software will be installed i will patched it and then try to create db.
I hope that after new adapter configuration i will not have listener configuration issues no more.
thx for help Adnan,
cheers.

Oracle 10g installation questions

Hi,
I tried to install Oracle 10g (Enterprise Edition) on Windows 2000 server, and encountered the following error when I used the Database Upgrade Assistance to ugrade one of my existing Oracle 8 database TEST.
ORA-01658: Unable to create INITIAL extent for segment in tablespace USERS.
I searched the forum, and seems that there is not enough space for my USERS tablespace. Is it the right solution?
If I clicked Ignore for the above erro, another error appeared:
ORA-00942: table or view does not exist.
I don't have table or view in TEST database, it is just a database instance created by Oracle 8. Do I have to create tables or views in order to upgrade it to Oracle 10g database?
I tried to upgrade an existing Oracle 8 database TEST1 which has data in it, and got the following error:
ORA-01119: error in creating database file D:\oracle\oradata\test1\sysaux01.dbf.
ORA-27044: unable to write the header block of file.
One last question is that after the failing of the DBUCA, I was told that the 10g was successfully installed on my server while no orcl database was created even if I chose
to create a database orcl during my installation.
The following are services running for 10g after the installation.
OracleCSService Started
OracleOraDb10g_home1iSQL*Plus Started
OracleOraDb10g_home1SNMPPeerEncapsulator
OracleOraDb10g_home1SNMPPeerMasterAgent
OracleOraDb10g_home1TNSListenerLISTENER10 Started
Anybody has any idea what went wrong?
Your early reply is greatly appreciated.
Jane

I believe the answers are:
1. the Oracle client needs to be the same bits as the TimesTen server. i.e. if you have 64b TimesTen, then you will need 64b Oracle client. If you have 32b TimesTen then you will need 32b Oracle client.
2. Yes. I believe you can install 64b TimesTen with 64b Oracle client and connect this to a 32b Oracle server. I dont have any idea about performance overhead of this configuration.

Oracle 10g Install Question

Hi All,
I have to install oracle 10g onto a server where there is existing oracle 9i software.
Is it safe to go ahead with the install, while the 9i databases are up?? what are the consequences of doing this?
OS patches and kernel parameters as required for oracle 10g have already been changed.
10g is being installed into a different oracle home and i would choose not to overwrite any of the files as asked by root.sh script.
OS is hp-ux 11i (11.11).
Thanks & Regards
Chandar

Hi,
Thanks for your reply.
Sorry for not being clear in my question earlier.
I am planning to install Oracle 10g on a server with existing 9i software. My question is whether we should shutdown all 9i databases for the duration of the install or we can leave them running as long as we do not overwrite any 9i files including files in /usr/local/bin directory that contains oranev etc...
To be on the safer side it is always recomended to shutdown any oracle instances running before we start the install. Wanted to know the consequences if we have them up and running for the duration of the install.
Thanks & Regards

Oracle 10g Listener XP pro need to be restarted ...

Hello all.
Here is my problem. I have oracle 10g installed on a computer with Windows XP pro Sp1a. Every thing work fine despite 1 point. When the computer is restarted, a small software starts the different Oracle Services (Oracle Database Service and listener) and wait for the 2 services to be in the state "started". After startup, the two services are in the state "started" but, sometimes, I can not get connected to Oracle. In the listener log, I have a message "TNS-12514: TNS:listener does not currently know of service requested in connect descriptor".
To solve the problem, I have to restart either the listener service or the oracle service or both of them.
My problem is that this computer must be an "auto starting system".
What can I do to solve this problem ???? Is there a specific order to start the process ?, Should I put dependency between them ???
Thank for your help.
D. GARRIVIER

If you use, as I think, dynamic service registration (no SID_LIST in Listener.ora for your DB), then it would be better to start the listener before the Database. If not, the registration could take a few seconds (or minutes). Anyway, if this is the problem, you should be able to connect after a few seconds (or minutes).
