Hi,
I am new to RAC. My environment: 10gAS (two nodes), 11gr2 RAC (2 nodes), on solaris10. I see all end users connecting to one node only. where other node is fine.

Hello all,

He using oracle 8i client on windows7
Database is 10G RAC and load balance is on in both database and client
please provide the solution

Hi,
Also I am not sure whether 8i client is certified with 10g database or not.
Do you have a metalink account. Read this Doc ID 207303.1

Which user connected from which node in RAC

Hi All,
I have installed 2-node Oracle 10g R2 RAC on RHEL4. It is working fine. Now i want to know which user connected from which node, how can i know this details?
Thanks,
Praveen.

You can use the gv$ views which actually submit the query ran against them to all instances of Oracle for the RAC database.
The documentation for the gv$ views is the v$ view entry in the Reference manual.
As far as I know when you run RAC every v$ view is built on a gv$ view.

Very slow email connection on one mailserver only

I will try and keep it short but it is complex (to me!):
I have suddenly, since Friday 2 March, experienced very slow connection to one of my ISP's mailservers. Emails without attachments work ok'ish (a little "hesitantly"), emails with attachments of moderate sizes (eg. +/- 500 KB) download/upload extremely slowly and most of the time fail. I have asked my ISP, who are generally helpful, and they have tested the mailserver and can find nothing wrong. So, here we go:
The problem is both for ethernet and wireless.
The problem is for one account only. I have a different account with the same ISP, but on a different mailserver, which works absolutely fine.
Two different Macs have the same problem. The other PCs with different ISP's accounts work fine.
Router is working fine with good internet connection and email via one of the two accounts works fine.
It is not a problem on my computer (since it is the same issue for two machines). Both run OSX 10.6.8
I have tried both Entourage and Outlook on both machines; same problem everywhere - one account works, the other doesn't (properly).
I have tried with my iPhone, using the same wireless connection and same account details, and it downloads emails with attachments speedily - emails that failed to download on the MBP/Outlook.
I have tried one of the machines (a MacBook Pro) at home with a different wireless connection but to the same mailserver and it works fine there!
This happened last Friday and no settings have been changed locally for months.
My conclusion is (but may be wrong):
The router is fine
The macs are fine
The email clients are fine
General connection to internet and mail is fine
The mailserver is probably fine
But a connection between one mailserver account and the two macs has suddenly gone wrong.
It is almost as if there is a setting on either the mailserver saying "I don't like that connection to that place, I will slow it down." or somewhere in this place saying "I don't like that account on that mailserver, I will slow it down."
The question then is:
Which network setting is so specific that it can be this selective? And why did it suddenly happen?
I don't seem to get anywhere, so I'm trying the communities. Any help much appreciated!

Update: After two weeks of scratching my head trying to find any local settings (computer or router) that were specific enough and after really not doing anything at all, normal service resumed suddenly. I have now had a good short week without any disruption or speed issues. The problem that was is still a mystery, though.

All connections are connecting to 2nd node only in a 2 Node RAC Cluster

Hello,
I have a 10.2.0.3 database on a two node RAC Cluster with only one service configured. This service set to be preferred on both nodes.
However, all the connections are falling on Node2 only. Any idea where to look.

Delete all the user connected to one transaction.

During some periods, we need to lock some transaction to avoid user modify data while we are processing some critical jobs.
If the users are yet in the transaction when we lock the transaction they are not removed from the transaction and we need to kill them manually from SM04 transaction in each application server.
I have been trying to adapt the RSM04000_ALV program to do this but i'm stuck with the use of the pooled session.
I guess that the system when you select the session and click on end session, it mark in anyplace something to indicate to the fuction module TH_DELETE_USER that when the option ONLY_POOLED_USER is enable, only that session need to be killed.
Anybody know how this works? someone have a similar fuctionality in you system?

We get the information from Audit of our production.
Someone accessing the production from client/desktop whose session is not traceable. Is there a way to trace the information who accessed it.
we are on 9.2.0.8 database

10g RAC Connecting with one node down.

We're are currently running version 10.1.0.2.0 on RAC, on Redhat Linux Enterprise 3, with two load balanced nodes - I have limited RAC experience.
Node 1 is currently shutdown, as a user tries to connect they get a 50% chance of success. An attempt is made to connect to node 1 and returns the following: ORA-12154 TNS: could not resolve connect identifier specified. Theyt can retry and eventually connect to node 2.
Is there anyway to stopping attempted connections to node 1 without having to modify all TNSNAMES entries?
Thank you,
David.

This is now resolved.
Thank you.

Connection in one direction only for MacBook

My airport network has worked fine for years with several computers and printers. Recently however a problem has developed. After awakening from sleep or from a restart my MacBook cannot connect to the other computers on the network. If I connect in the reverse direction, from one of the other computers to the macbook, there is no problem, and afterwards I can then connect from the MacBook to any other computer on the network. I haven't chaged any settings on the network properties, passwords, etc. Any idea why this is happening?

I did my reset and it seems to have speeded up the 3G iPhone somewhat but not cured these syncing anomalies.
I am syncing three way
Mobileme
MacBook iCal
iPhone iCal.
I have sent test diary dates from each source
Mobileme and iCal are playing nicely but the iPhone is sulking and won't receive or send diary events.
In my iPhone my Systems Prefs are...
Accounts: mobileme
Fetch new data: Push
my email on my iPhone is working well with email Mobileme and email on the MacBook is also working well with Mobileme.

Blog Loads Slow and Intermittent Internet Connection for One Site Only

Hi
Yesterday we had a site where the blog lost it's feed, but was restore after a chat with support. Today the blog post are not coming up in the admin. I can see the list, but the not the post as the flywheel keeps spinning and spinning.
When I go online, I can get to the blog fine, but when I click on the pagination links below or try to do a reload, the entire page gets lost or server can not be found.
I have re-uploaded all the Layouts and Templates, but with no change.
Anyone else having this issue, or is there something wrong with this site's blog?
All other pages and features are accessible from the browser and admin, just not the blog.
Thanks, Teejay

Hi Teejay,
If still experiencing troubles with your blogs please provide the following details so we can attempt to replicate on our end..
- blog name or url
- steps you are taking (where you are noticing the slowness)
Or if you would rather you could also provide a quick video cast or your experience so we can investigate further.

Slow Connection Speed on one node in a 2 node RAC set up

hi all
Having a bit of trouble with one of the nodes in a 2 node RAC set up
We have traffic being sent directly to the node in question (using a serivce that only runs on Node 1)
Forced connection to this node (sqlplus) from a remote application server takes 3 times longer than it does if we force conneciton to the second RAC node.
If I try and connect locally - the conneciton speed is instant -
There are NO performance issues with the server
There are NO perfromance issues with the instance / database - this is only noticed when making the initial connection
I have been around the network for the node and can see nothing wrong - so was wondering if there was anything you guys might have experienced whereas conneciton time is slow for one node only (949 ms - compared to 247 ms on node 2)

If anyone out there is interested or comes accross this issue
The problem turned out to be mount point options pm the Linux Volumes
I had them configured as part of best practice for RAC / NetApp / Direct NFS - hjowever I also had individual binaries for both nodes so as to have greater availability.
Thereffore I should have had the mount options for SINGLE NODE.
Change was to
- shutdown the instance
- unmoiunt the binaries
- change the following on fstab
<mount> <volume> nfs rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600,actimeo=0 0 0
to
<mount> <volume> nfs rw,bg,hard,rsize=32768,wsize=32768,vers=3,nointr,timeo=600,tcp
- startup the instance and repeat on Node 2

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

EM DB console works only from one node?

In my 2 node RAC the enterprise manager database console works only from one node i.e the url shows login page only from one node.
http://NODE2:5500/em------>WORKS, SHOWS LOGIN PAGE AND CAN MANAGE ALL INSTANCES FROM HERE
http://NODE1:5500/em------>DOES NOT WORK, DOES NOT SHOW THE LOGIN PAGE.
Please clarify.
Kadhim

I have to guess ... (because you tell neither OS nor database version). Assuming it's 10gR2 or higher, that's expected behaviour, dbconsole runs on one node only, the so-called master node. You can change that, see the documentation or this metalink note:

Ports connected to End Users.

Hi,
Do you know any monitoring tool where I can see how many ports is using any Cisco switch and that I can export it to any software like Excel ?.
Thank you, best regards.

Yes, this is exactly the purpose of CiscoWorks Campus Manager's User Tracking component. User Tracking will find end users connected to switch ports by their MAC addresses. It will then correlate ARP table entries from managed routers to populate IP information. Finally, using a small piece of software running on Windows end hosts, UT can show the username of the user connected to the port.
A 90-day eval of CiscoWorks LAN Management Solution can be downloaded from http://www.cisco.com/go/lms/ .

End users connecting to one node only !!
