Why scan listener has only 1 instance registered ?

hi all ,
i met this problem these days
my environment RAC03 has 2 nodes : RAC03A and RAC03B
using "lsnrctl services" checked the local listener, i found there are too many request established on RAC03A, but RAC03B has quite few request……
then i checked the scan listener

the service has two instance registerd on RAC01, but RAC03 is not.
i tried " alter system register " in two nodes, but it's no use at all :(
how could i add the other instance on RAC03 registered in the scan_listener?
thanks a lot!

i did what you said
1) stop scan_listener and scan
2) kill the listener_scan1 process on RAC03A
3) start scan and scan_listener
then i checked the status of scan_listener
at first , the scan_listener on RAC03B still had 1 instance registered (the local instance),
so i rebooted the OS(RAC03A)
after that , it finally works!
now the scan_listener on RAC03B has 2 instances registered(the local one and the remote one)

Scan listener for single instance

Hi,
in my 6 node 11.2 cluster, i've 1 single instance 11.2
This instance uses GI listener and i can be accessed using host vip.
Using the scan i get ora-12514.
Why?
Thanks.

Hi,
"SCAN listeners can run on any node in the cluster. SCANs provide location independence for
databases so that the client configuration does not have to depend on which nodes run a
particular database.
Oracle Database 11g Release 2 and later instances register with SCAN listeners only as
remote listeners. Upgraded databases register with SCAN listeners as remote listeners, and
also continue to register with all other listeners."
"When a client submits a connection request, the SCAN listener listening on a SCAN IP
address and the SCAN port are contacted on the client’s behalf. Because all services on the
cluster are registered with the SCAN listener, the SCAN listener replies with the address of
the local listener on the least-loaded node where the service is currently being offered.
Finally, the client establishes a connection to the service through the listener on the node
where service is offered. All these actions take place transparently to the client without any
explicit configuration required in the client."
So scan redirect to the vip in which the instance is running.

Password for SCAN Listener.

Hi Team,
Is any one know how to set the password for SCAN listener in 11gr2?
Is it similar way as normal..!

Regards,Do you understand that why SCAN listener is there in the first place? This is not to going to be any use for client communication . The only time it would come into the picture is when there would be a resolution requirement for a local listener. Now, the question for you is, why you even want to set a password for it? Did you see the entry in the listener.ora which says that these listeners are added by an agent which means, there is nothing that you need to do for them?

Why does listener show +ASM1 as BLOCKED

I did a lsnrctl status on the listener and it showed that +ASM1 status as BLOCKED. Why does listener show ASM instance as blocked? How does the agent connect to ASM instance if it is blocked?
Thanks

Hi,
I assume the ASM entry that you are showing refers to what should be in db_1/network/admin/tnsnames.ora?
My tnsnames.ora does not have an ASM entry at all, and I am experiencing the same issue as the original poster. Should I add one and restart ?
Thanks,
Colm.

How prevent REMOTE LISTENER register on SCAN LISTENER

Hi All,
Oracle Database 11.2.0.3
How prevent remote registration on SCAN Listener?
I need to know if there is a way of prevent one instance register on listener using remote_listener parameter without affect incoming connection of client.
These parameter below is not enough to meet my tests:
tcp.validnode_checking = YES
tcp.excluded_nodes = {list of IP addresses}
tcp.invited_nodes = {list of IP addresses}The tcp.excluded_nodes and tcp.invited_nodes parameters deny and enable specific client IP addresses from making connections to the Oracle listener.
Levi Pereira

Yes, I posted about that 4 days ago:
Re: Local Listener Validity in 11gR2
I have not yet had an opportunity test it, have you successfully tested the procedures? Basically it forces all registration event to occur over IPC/TCPS. I have seen the original test case for this, and while yes, it is true that you can connect if this is not in place, it is a very complex man-in-the-middle vulnerability requiring access to your [hopefully firewalled] database server.

When i try to send email from my ipad i get the message The recipient "£)()&&£)" was rejected by the server. This has only just started to happen and I don't know why. Please help. I have tried lots of things now and cannot solve it.

"Your email account" means to tap on the name of your email account. Whatever it is listed as in the settings.
In my mail settings, one of my email accounts is a Comcast account. I tap on the Comcast name and it brings up this window.
Then I tap on the arrow under the Outgoing mail server smtp setting to get to the next window.
In the resulting window, I then tap on the arrow next to the smtp server under the Primary Server setting.
That brings up this window in which I check to make sure that my user name and password have been entered correctly. If those items are missing, enter them in the appropriate fields and then tap done.

SCAN LISTENER runs from only one node at a time from /etc/hosts !

Dear all ,
Recently I have to configure RAC in oracle 11g(r2) in AIX 6.1 . Since in this moment it is not possible to configure DNS, so I dont use SCAN ip into the DNS/GNS, I just add the SCAN ip into the host file like :
cat /etc/hosts
SCAN 172.17.0.22
Got the info from : http://www.freeoraclehelp.com/2011/12/scan-setup-for-oracle-11g-release211gr2.html#ORACLE11GR2RACINS
After configuring all the steps of RAC , Every services are ok except SCAN_LISTENER . This listener is up only one node at a time . First time when I chek it from node1 , it shows :
srvctl status scan_listener
SCAN listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node dcdbsvr1
now when I relocate it from node 2 using
"srvctl relocate scan -i 1-n DCDBSVR2" , then the output shows :
srvctl status scan_listener
SCAN listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node dcdbsvr2
Baring these , we have to try to relocate it from the node2 by the following way, then it shows the error :
srvctl relocate scan -i 2 -n DCDBSVR2
resource ora.scan2.vip does not exists
Now my question , How can I run the SCAN and SCAN_LISTENER both of the NODES ?
Here is my listener file (which is in the GRID home location) configuration :
Listener File OF NODE1 AND NODE 2:
==================================
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON
LISTENER_SCAN1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC) (KEY = LISTENER_SCAN1)
ADR_BASE_LISTENER_SCAN1 = /U01/APP/ORACLE
2)
Another issue , when I give the command : " ifconfig -a " , then it shows the SCAN ip either node1 or node2 . suppose if the SCAN ip is in the node1 , and then if I run the "relocate" command from node2 , the ip goes to the Node 2 . is it a correct situation ? advice plz ... ...
thx in advance .. ...

After configuring all the steps of RAC , Every services are ok except SCAN_LISTENER . This listener is up only one node at a time . First time when I chek it from node1 , it shows :If I am not wrong and after looking at the document you sent, you will be able to use only once scan in case you use /etc/host file and this will be up on only one node where you added this scan entry in /etc/hosts file.
Now my question , How can I run the SCAN and SCAN_LISTENER both of the NODES ?Probably you can't in your case, you might run only one i think and on one node only
srvctl status scan_listener
SCAN listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node dcdbsvr1
now when I relocate it from node 2 using
"srvctl relocate scan -i 1 -n DCDBSVR2" , then the output shows :
srvctl status scan_listener
SCAN listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node dcdbsvr2You moved scan listener from node 1 to node 2, OK
Baring these , we have to try to relocate it from the node2 by the following way, then it shows the error :
srvctl relocate scan -i 2 -n DCDBSVR2
resource ora.scan2.vip does not exists
--------------------------------------------------------------------------------Since you have only one scan, you can't relocate "2". So ise "1" instead here also

Photos from the Internet will not load correctly. I get white boxes with blue question marks inside. This has only been happening for the past 3 weeks so I'm not sure why it is happening.

Yes - email & text work fine but when I use something like Google Images or search a blog with imbedded photos I get the empty white boxes with question marks. If I click the question mark it opens the photo but I can't possibly do that for EVERY image on EVERY page I search!?!?! I've rebooted the iPad & my wireless card several times but neither action helped. Have any clue what I should do now?

The message is correct. You can only register a product once... there is no need to register again after you do it the first time. You can re-install and activate with the serial number, but there is no need to re-register.

Re-registering a listener with an instance

What are the options for registering a listener with an instance? Obviously you can restart the instance, but what options do you have if you want to reregister w/o restarting the instance?

as SYSDBA, execute
ALTER SYSTEM REGISTER;
Minor correction in your terminilogy ... the instance is registered with the listener, not the other way around. By registering the instance's availability to the listener, the listener then knows it should be listening on behalf of the instance (or service).

I have time machine saving onto two usb drives. The backup is 4.6TB. Each drive is 6TB. Why is time machine only updating one drive? (The other has been the same for two weeks.)

I have time machine saving onto two usb drives.
The total size of the files being backed up is 4.6TB.
Each external USB drive is 6TB. So I have 12 TB of space for Time Machine.
Why is time machine only updating one USB drive? (One drive has been the same for two weeks.)
I have selected both drives in the Time Machine settings panel.
My understanding was that it would do a full backup, and then incremental backups of changed files, getting rid of old copies as needed, and alternate between the two drives.
But it looks like drive A has one complete backup, dated two weeks ago, and drive B is the only one getting action.
There is a red icon on drive one that says the drive needs 120GB more space to do a backup -- which is strange since the whole backup set is only 4.6TB in size, and the drive is 6TB in size...

But it does not for the scan listener:

PRCR-1105 : Failed to relocate resource ora.LISTENER_SCAN2.lsnr to node rzsolv236

PRCR-1090 : Failed to relocate resource ora.LISTENER_SCAN2.lsnr. It is not running.
[oracle@rzsolv236 ~]$
Any ideas?

Hi,
thank you, but this does not match to my problem:
- those socket files are owned by oracle:oinstall on both nodes, I deleted them to give it a try but no change
- I can start the LISTENER_SCAN2 on node 1 using lsnrctl when node 2 is down, but I cannot using crsctl and GI does not check it when I start the listener manually
- GI seems to be kind of confused about the state of the LISTENER_SCAN2 while node 2 is down (is already in the INTERMEDIATE state on server 'rzsolv236' vs. OFFLINE state in crsctl stat res -t)
see output below ...
[oracle@rzsolv236 ~]$ crsctl stat res -t
