Listener target is offline on rac database

hi all,
os-linux
oracle 10.0.2
i am using two node rac (rac1,rac2).
i used rconfig for converting a non rac database to rac database.
Everything is working fine but when i fire command crs_stat
i am getting
NAME=ora.rac1.LISTENER_RCONFIG_RAC1.lsnr
TYPE=application
TARGET=OFFLINE
STATE=ONLINE on nrac1
NAME=ora.rac2.LISTENER_RCONFIG_RAC2.lsnr
TYPE=application
TARGET=OFFLINE
STATE=ONLINE on nrac2
please give me the solution.

What is the output of:
crs_stat -v ora.rac1.LISTENER_RCONFIG_RAC1.lsnrTry to stop listeners and and to restart them with crs_start:
crs_start ora.rac1.LISTENER_RCONFIG_RAC1.lsnr

Will Nodeapps register the listener service of RAC database?

Hi Friends,
In 10g RAC will Nodeapps register the listener service of RAC database?
because if i bring down nodeapps the listenener is also going down

Hi,
This is expected behavior. The default listener (listener_nodename) could be starte and stopped with nodeapps.
srvctl listener is mainly for specific listeners that are other than default.
http://docs.oracle.com/cd/B19306_01/rac.102/b14197/whatsnew.htm#sthref6
If you create additional Listeners with non-default names, in other words, with names other than the name listener_nodename where nodename is the name of the node on which the Listener resides, then you must start and stop these Listeners with SRVCTL commands.

Add RAC database as a target for EMC 12c

Hello,
I have installed Enterprise manager 12c on Host 1 Redhat linux 5.5
We have already installed a RAC database 2 nodes on Host 2 and Host 3 ; RAC version 11.2.0.3 on Redhat linux 5.5.
I am planning to add the RAC database to be monitored by Enterprise manager 12c.
I am going to deploy the agent using the following video: http://www.youtube.com/watch?v=dP-8Bw8CVu8
How to add the RAC database to be monitored by the Enterprise manager 12c after the agent deploy on hosts: Host 2 and Host3?
Thank you,

NETCA listener configuration error for RAC database

Hi,
WE have a RAC setup on 2 nodes and now we want to change the default listener port for RAC database.
Database ver: 10.2.0.4
We now that srvctl does not work to add listener manually to CRS.
We are now using netca to create new listener on both the RAC nodes but it gives error throwing :
Problem in configuration : Node(S): hostname
Try again...
When we try to start the listener say listener_I it throws following error:
Problem in configuration :node1
Listener start to failed:Listener may already be running
CRS-0215:Could not start resource
This is urgent
any help is appreciated.
Regards,
Milan

How to register RAC database to new listener manually in 10g?

Hi Rac Experts,
OS : Red Hat Enterprise Linux AS release 3 (Taroon Update 6)
Oracle 10.2.0.2.0 database
I am working on to register my two node RAC database to the new listener which i have created manually, after listener creation when i start the listener it only handles local instance but not the remote instance. Please advice....
Please note that netca is not working on this machine and i am working from remote location, so i don't have gui access from here.
Following is my listener on node1:
LISTENER_OR44D1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = virtual ip)(PORT = 1527)(IP = FIRST)))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = actual ip)(PORT = 1527)(IP = FIRST)))
SID_LIST_LISTENER_OR44D1 =
(SID_LIST =
(SID_DESC = (ORACLE_HOME = /u01/app/oracle/product/oracle10/db)(SID_NAME = or44d1))
-- PTLDBA.

Hi,
I did as per you advice but facing below error, i am i missing anything here. Please advice...

This error means that the hostname or IP address used in the TNS connection string, failed to resolve or connect.
Your client is making two connections. The first connection is to the SCAN listener. It matches a db instance for your connection request based on service requested, available registered service handlers, load balancing, and so on. It then send a redirect to your client informing it of the handler for that service.
Your client then does a second connection to this service (a local RAC listener that will provide you with a connection to the local RAC instance). This is what seems to be failing in your case.
The SCAN listener's redirect uses the hostname of the server that the local listener is running on. Your client needs to resolve that hostname (of a RAC node) to an IP address. This likely fails.
You can add the RAC node hostnames to your client platforms hosts file. The appropriate action however would be to ensure that DNS is used for name resolution instead.

Question about DBCA generate script o create RAC database 2 node cluster

Question about creating two node RAC database 11g after installing and configuration 11g clusterware. I've used DBCA to generate script to create a rac database. I've set
environment variable ORACLE_SID=RAC and the creating script creates instance of RAC1 and RAC2. My understanding is that each node will represent a node, however there should only be one database with a name of 'RAC'. Please advise

You are getting your terminology mixed up.
You only have one database. Take a look, there are one set of datafiles on shared storage.
You have 2 instances which are accessing one database.
Database name is RAC. Instance names are RAC1, RAC2, etc, etc.
Also, if you look at the listener configuration and if your tnsnames is setup properly then connecting to RAC will connect you to either one of the instances wheras connecting to RAC1 will connect you to that instance.

ORA-20600 error while trying to add RAC database

I'm receiving the following error while trying to add the RAC database in grid control. Any idea?.
ORA-20600: The specified target is in the process of being deleted
This database doesn't exists in targets. But, I'm still unable to add.

Check the metalink Note: Unable To Add Rac Database To Grid Control Getting Error Ora-20600 [ID 1218797.1]
You need to wait for a while and check the status.

Multiple RAC databases on same GI using different subnets for Public i/face

Hello. We are configuring a 2 node cluster. That cluster will host several RAC databases. For security reasons our networking team want to create separate subnets for the application traffic to each specific RAC database on the cluster.
E.g. application 1 has 2 application servers that will connect to RAC database PROD1 via one subnet, application 2 has 3 application servers that will connect to RAC database PROD2 via a different subnet, etc.
In addition the networking team want to configure a separate management subnet that DBAs etc. will use to administer all RAC databases and infrastructure in the cluster.
Grid Infrastructure version 11.2.0.2. Database versions will vary from 10.2.0.x to 11.2.0.2. All databases will utilise RAC.
We want to take advantage of SCAN listener functionality to support connectivity to all databases on the cluster. Forum thread 2199620 [https://cn.forums.oracle.com/forums/thread.jspa?threadID=2199620] suggests that 11gR2 supports multiple subnets, which looks to be exactly the feature we need. Please can you confirm how this works and point us to any documentation (standard docs, white papers, MOS, etc.) that might help us configure this.
Document referenced in thread 2199620 was not exactly what we were looking for, and didn't translate too well in Google Translate.
Any guidance much appreciated. Thanks, Rich.

Thanks Levi. Your advice is very much appreciated.
Your statement that we can only have one SCAN listener listening on one public network is actually the clarification I was looking for.
For anyone else reading this thread I believe this gives us 3 options:
1) Configure a SCAN listener and have all applications, and all management/administration, connecting to the corresponding database on the same cluster via that SCAN listener, all on the same subnet.
2) Configure a SCAN listener for use by all applications connecting to the corresponding database on the same cluster, and use TNSNAMES/VIP for management/administration traffic, both on separate subnets (by configuring the LISTENER_NETWORKS parameter)
3) Configure a SCAN listener for use by applications connecting to one of the databases on the cluster via one subnet, use TNSNAMES/VIP for all other applications connecting to other databases, each using their own subnet. Plus, the management/administration could be via another subnet utilising TNSNAMES/VIP.
From our perspective we will work out the best one for us and implement accordingly.
Thanks again for your timely and comprehensive response.

Help needed in deleting nodes from RAC database

Our DB is 10g RAC database and the servers are Window 2003 server. Initially the database was configured to have 4 nodes. For some reason we stopped the instances in the first two nodes and the current database is running on node3 and node4. I queried the v$thread view and it shows 3 records. Thread 2 is closed and disabled. Thread 3 is open and public and thread 4 is open and private. Now we need to disconnect nodes 1 and 2 from RAC db and cluster ware (We use Oracle cluster ware) and plan to use those two servers for other purposes. Although I read through the Oracle doc regarding deleting node from RAC “11 Adding and Deleting Nodes and Instances on Windows-Based Systems” and wrote down the steps we need to take but I am still not comfortable in doing it since it is production env and we don’t have any dev env to practice those steps. So I would like to borrow your experiences and your lessons learned while you were doing those. Please share your thoughts and insights with us.
Thank you so much for your help,
Shirley

what's your full version? I can warn about specific issues in 10.1.0.3 and 10.2.0.1 - for example, in some cases (depending on how the listener was configured), it will be impossible to delete the listener for the deleted node. Known bug.
To avoid many many known bugs, you may want to upgrade to at least 10.2.0.2 before removing a node (from my experience, this is the first stable RAC version).
In any case, deleting a node is a rather delicate process. I really really recommend practicing. Take any pc/laptop, install VMWARE, define two virtual machines, install RAC and remove one node. It will take you an extra day or two, and could save your production.

How to install Oracle 11.2.0.4.0 Rac Database on Grid Infrastructure 12.1.0.2.0 (Windows 2012 R2)

Hi all.
This is the scenario:
I have a 2 node cluster Microsoft Windows 2012 R2 x86_64, the nodes are part of domain.
Installed Oracle 12cR1 (12.1.0.2.0) as follows:
Installation done using domain administrator named "installoracle" that has been EXPLICIT promoted to local administrator in both nodes.
One domain user named "oracle12c" with no administrator privileges neither in the domain or nodes.
Installation, after a lot of customization in the OS of the nodes, has gone ok, perfect indeed, not even a warning during runinstaller execution.
All services and resources are up & running, I have rebooted nodes and all comes back ok in place. In windows services I can see some services started with "oracle12c" user, and all windows groups: DBA, SYSKM, etc, has been created.
Now I have to install Oracle RAC database in 11gR2 version (11.2.0.4.0) to accomplish with application requirements.
So, I execute runInstaller (setup.exe) logged as administrator via domain administrator "installoracle" (the one that was able to do the smooth 12c GI installation) and the gui comes with out problems, but at 4th screen the one in which you have to choose what kind of installation you want to do (Single, RAC or RoN) I select RAC option, the gui returns error: crs is not running in the local node...
Finally, in order to deliver some database 11.2.0.4.0 for my customer, I try to do installation of SW for Single Node, I did using "installoracle". The sw has been installed in one of the nodes. Then I have created a database and I have stored datafiles in ASM (this ASM is part of 12c clusterware) and also register the 11gR2 single instance database in the Grid Infrastructure listener
So, whats next??? Why is this behavior??? I did similar installations in Linux/Solaris with no issue (well as everyone can imagine, always there are some issues, but when solved you got GI in 12c and databases in the release that you want 12c, 11g, 10g...)
Any clue?
Thanks in advance!!
Best Regards!!

To go back to old version (without changing compatible parameter), you can perform downgrade.
Instructions are available at
How to Downgrade from Database 11.2 to Previous Release (Includes 11.2.0.4 - 11.2.0.1) (Doc ID 883335.1)
In this case you will having all the data file including the new one.
But remember database may not be in the same status as before (Before upgrade). it may have invalid objects of higher version after downgrade.
Downgrade is applicable only to successfully upgraded databases. In case upgrade faced some issue, do not try downgrade there.
Your second approach it not correct. Note that each datafile header will have db version. We can not open database in normal mode when header version and binary versions are different.

Data Guard configuration for RAC database disappeared from Grid control

After adding a logical standby database through Grid Control for a RAC database, I noticed sometime later the Data Guard configuration disappeared from Grid Control. Not sure why but it is gone. I did notice that something went wrong with the standby creation but i did not get much feedback from Grid Control. The last thing I did was to view the configuration, see output below.

Perform a live backup of the primary database
Specify backup directory for staging area
Specify standby database name and Oracle home location
Specify file location staging area on standby node
At the end am presented with a review of the selected options and then the standby database is created
Has any body come across a similar issue?
Thanks,

Any resolution on this?
I just created a Logical Standby database and I'm getting the same warning (WARNING: No credentials available for target ...) when I do a 'Verify Configuration' from the Data Guard page.
Everything else seems to be working fine. Logs are being applied, etc.
I can't figure out what credentials its looking for.

Configured TNS in oracle client to RAC database

Hi Experts,
I have a 4 nodes oracle RAC in radhat 5.0
both oracle database and client as 10.2.0.4.
I created a TNS that works in our office but it does not work in our remote brance office.
Based on experts instruction, I set up sqlnet trace at client side. but not any file that be gererated.
In linux RAC database, I saw listener.log file as

SQLNET.SEND_TIMEOUT = 500
SQLNET.RECV_TIMEOUT = 500
I got a error as
ERROR:

which wrong is in my case?
I can connect to all other window database from thsi PC.But I can not connect to RAC database from this PC.
However, I can ping RAC node's IP and VIP from this PC
I also can connect to RAC database with TNS from other window PC.
What do I need to do?
ThanKs for any help.
JIM

Hi Sb92075,
Thanks for your help.
I got same error after comment #SQLNET.AUTHENTICATION_SERVICES= (NTS) in client sqlnet.ora in client.

Time to connect to RAC database

Hi,
I have installed 11gr2 RAC database on windows server 2008 on ASM. I can connect to existing prod db withing a second but it is taking almost 20Seconds for me to connect to the RAC database. Is it because of the SCAN IPs?
Can anyone let me know the reason behind it and the resolution on it?
Thanks...

Yes, some TNS connections can be slower than others. There are a number of factors. The initial connection may result in a redirect to another listener on a different IP address (e.g. load balancing). This will be slower than a direct connection (no redirect).
In such a case for example, where a redirect occurs, the client with receive a redirect to a new hostname. It needs to resolve that to an IP. This can be slow due to DNS issues (either with the DNS itself, or with the resolution scope config of the client).
The connection can request a dedicated sever instead of a shared server. A shared server connection is simply a hand-off of that client to an existing dispatcher process. A dedicated server connection requires the Listener to launch a brand new Oracle server process, for that process to attach itself to the SGA, and then resume the connection/conversation with the client. Thus shared server is by its nature a lot faster to establish a connection with than a dedicated server.
So there are a number of moving parts that can be slow. And you will need to isolate these and test each in turn to determine where the performance knock is.

Listener target is offline on rac database
