• ANALYZE the listener to the top, local listeners down

  Versions DB: 11.2.0.2

  You have a 2-node RAC. SCAN listeners are running on both nodes. But local (using VIP) listeners on both nodes are down.
  In this scenario, is it technically possible for a client remote IE. SQL * more, java, etc., connecting from outside the Server DB to connect to DB throug, none of these cases?

  Hello

  As far as I know... MOM

  The listener to SCAN aims to redirect the connection to the Local listener.
  When a SCAN listener receives a connection request, the listener ANALYSIS will check the instance less responsible for providing the requested service. It will then redirect the connection request to the local listener on the node where the least loaded instance runs. Subsequently, the customer will be given the address of the local listener. The local listener will finally create the connection to the database instance.

  The listener ANALYSIS does not connect to the database. Therefore, if the Local listener is down... Your clients will not connect in your database, because there is no listener that creates connections to the database.

  The below error will be triggered.

  ORA-12516: listener could not find available handler with matching protocol stack

• Local listener and listener to Scan

  In a 11.2.0.4 cluster can you set the local_listener and the scan_listener run on the same port 1521.

  In a 11.2.0.4 cluster can you set the local_listener and the scan_listener run on the same port 1521.

  Yes. You may think two headphones can not use the same TCP port in a server. But, remember, Local listener is running on the node RAC VIP and listener to SCAN runs on SCAN IPs that are different from the public IP/VIP to each node.

• Issue of the listener to RAC

  Hi all
  
  I have a 2 RAC node and when I run the lsnrctl services command on node 2, I get a list of services, but when I run the same node 1 I get
  
  The listener supports no services
  
  is this normal or should I receive a list on both nodes?
  
  I'm essentially looking to get to the bottom of why one of my databases on this implementation RAC keeps giving me an IO exception: the network adapter could not establish the connection in EM, but I failed to find an actual error for this number yet.
  
  Thank you

  Hello

  Well, it worked

  [Im happy:]

  I don't understand why. Now I have the Listener.ora files on both nodes which look different with what you put and that without it, why is this?

  The listener expects the requests from Clients to connect to the Instance. It receives connection requests incoming clients and handles the traffic of these requests to the database server.
  For example: If node 1 is down, listener node redirection 2 while waiting request to node 2. This listening port on both nodes must be different.

• Problem with the listener in environment of multiple databases

  Hello world!

  I have a server that is running about 10 databases. And 5 listeners who manage these databases. Some listener manage 1 DB, another can handle more than 1.

  Listener ESSENTIALS that I create the first run (top of the listener.ora file), only 2 DB. But when I show the status of the listening port, it shows the listener to manage all DBs.

  Another listener works normally.

  Could you help me solve the problem?

  Thank you!

  TuanNV

  You must set the LOCAL_LISTENER parameter in each instance to control what other they register with. You have probably enabled by default, so they all register with all that is listening on port 1521.

  Moreover, some people here get mad at the idea of running more of a listener. Be warned.

• Running the Single Instance and RAC on the same server of different homes.

  Hi guys,.

  I already have 4 node RAC12c installed on OLE 6.

  I'm planing on some of my other 12 single instance databases on other migration for RAC nodes.

  Please correct me here if I am wrong...

  My understanding is that, to be able to use DBCA or rconfig for conversion of database instance RAC, the only instance and RAC cluster must run on the same server or machine node.

  Thanks to this understanding... Am planing on the installation of a binary single instance on one of my cluster node node1 say and then use RMAN to duplicate the single instance or just an RMAN restore from the node of the instance that is unique to this node1. Am capable of this plan must then use DBCA or rconfig to convert the CARS database.

  Now, my question is can I run a single instance and RAC on the same server for different homes with different database ports?

  2. for these unique instance that runs on the server RAC 1 node, can I use the RAC database listener that runs from the House of the grid or I have to create another auditor?

  Thank you in advance and also let me know if I can use DBCA or rconfig when the only instance and rac database are on separate nodes.

  K

  Fix. And that's what I would normally do. In general, I would have just an ORACLE_HOME directory that can be used by the punctual and RAC databases at the same time.

  See you soon,.

• Questions of the listener after having changed their name and intellectual property

  Hello!

  I really hope someone can help me.

  I had a fully functional Oracle 11.2.0.4 Server (windows 2012).  I changed the ip and name server and rebooted.  When the server came back to the top, I rebooted the oracle service.  I then started the listening service.  The listening service would not start. I know I forgot to change the tnsnames file. So I changed the tns to use my new hostname, but there seems to be a problem with the listener.

  When I deleted the listener is took forever before he returned and said it has been deleted.

  When I try to recreate the listener, he says that there is already a listener with this name.

  Right now I'm no. Listener service window.

  If I'm trying to create the listener with a new name, it says that the port is in use.  I even started the server, but the port is still used.

  It seems that the auditor still considers that the name of the server is 99walnut, then it should be my new name.

  "lstnrctl State" indicates the old name of the HOST and errors:

  so I'm in search mode and finally, after many moons a lot and light years away, I found the following

  Here's what I did

  # - scan

  192.168.0.127 rac31 - scan.oracle.com rac31-scan

  192.168.0.128 rac31 - scan.oracle.com rac31-scan

  192.168.0.129 rac31 - scan.oracle.com rac31-scan

  I put three ip addresses in the host with the same name rac31-scan file

  then I put the same ip addresses in my windows hosts file

  Here are the entries

  192.168.0.127 rac31 - scan.oracle.comrac31-scan

  192.168.0.128 rac31 - scan.oracle.com rac31-scan

  192.168.0.129 rac31 - scan.oracle.com rac31-scan

  but in the (windows 7 pc) client tnsnames file has just one entry

  It's here

  RAC1 =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP) (HOST = rac31-scan)(PORT = 1521))

  (CONNECT_DATA =

  (SERVER = DEDICATED)

  (SERVICE_NAME = RAC)

  )

  )

  and now when I connect from the client... it connects without any problems.

  I have tried more than 10 attempts without problem

  BINGO!

• RAC, listener to scan and firewall

  Hello

  We have a 11.2.0.3.8 SE RAC on linux 6.5 server two oracle. An instance must be accessiable by clients behind one firewall, either case, not. My solution is a second local listener with a different port. If you know another way, I'll be happy to hear, thank you.

  Best regards

  Thomas

  There are a number of considerations.

  The TNS connect string wants to connect to a service. This service can have multiple points of termination (supported by a number of bodies and registered with the listener by these bodies).

  You can connect to server1 public static IP, port 1521 and ask a connection service dbname1. But as dbname1 was recorded by all RAC servers and that the listener also has port 1527 as tcp listener endpoint and addresses are used as a number of IP static and virtual - your client could very well be redirected by the database instance listener 5 Server5, via a virtual IP address and the port 1527.

  If a connection request by the client on port 1521 to server1, doesn't mean that's where the real Oracle client-server session will end.

  If you are planning that the static tcp, the listener port should only be listening on a single port. I've seen listeners set up for multiple ports (1521 and 1527), with only one port opened through a firewall, with intermittent connectivity - result as any other connection get a redirect to the other port.

  The listener also distributes host names (assuming a good config listener.ora and network) when the redirection of a client connection.  For example you connecting host server1 name and get a redirect to Server5.

  If server1 is only accessible IP the current network (firewall, etc.), we can address the redirect on the client - in solving all host names passed by the listener to the IP address that works. For example local hosts file customer resolve server1 Server5and server1-vip to Server5-vip, this unique IP to work.

  If you want a client to select a specific instance of the CARS to connect to (or force connections to a single specific instance), you can use the service_name parameter. This is by default the value db name and db-domain on multiple RAC instances. This means that all levels of RAC record the same service with listeners. Allowing a connection of client for this service will be handled by any instance RAC (high availability, etc.).

  You can also add a unique service for this instance RAC instance RAC. This service will be so registered by a single instance of the FCAC and the client connections requesting this service (connection via SCAN or other listeners CARS), will always get redirected to this forum.

  In the scenario you described, I would not use a secondary headset. I would like to use a unique service name to limit client connections to one specific instance of the CAR and the hostname/IP server. I would not use several ports tcp as listener endpoints. And then ask this IP and port to be open on the firewall and giving that service name to the clients that connect through the firewall.

• can't automate the listener on startup under redhat 6.3

  Dear oracle specialists I installed oracle 11g r2 on linux RedHat 6.3 after a successful installation and automating db departure

  can't automate starts high earpiece however able to start it manually since I was new as well bi for oracle in order to

  scripts Linux can help me find the error

• Confusion between issues of the listener

  Hi all
  
  SLES 11
  
  Step 1
  
  I installed the first db 10R2 on our server. He created a listener from 10g to port 1521. And the connection is good.
  
  Step 2
  
  Then on the same server... I installed 11 GR 2 XE with APEX epg configured on the listening port 1522. I purposely created its own listener APEX is very sensitive in connectivity of the listener.
  Two listener now the connection separately for each database.
  
  Step 3.
  
  Then on the same server... I installed 11 GR 2 EA and the listener uses port 1521. If this setting overrides the listener 10g... while I'm not disable it. And then began the 11 GR 2 new of the listener.
  
  It's now at this stage that the gr 10, 2 and 11 GR 2 EA have connection problems :(

  ERROR:
  ORA-12514: TNS:listener is not currently of service requested in connect descriptor

  can help you solve this problem please?
  
  Can I use 11gXE for gr 10, 2 and 11 GR 2 EE earpiece?
  
  Which 3 listeners I should alone running?
  
  
  Thank you very much
  
  zxy

  When you try to connect to a different database, you have the good ORACLE_HOME and ORACLE_SID?
