RAC: "srvctl config scan" output

Hi,
My company is using a RAC on Oracle 11gR2.
I am trying to undersand the beast and there is something I am stucked on.
we have this :
[root@devrac1 admin]$ srvctl config scan
Nom SCAN : <host>.<domain>, rÃ©seau : 1/10.12.2.0/255.255.255.0/eth0
Nom d'adresse IP virtuelle SCAN : scan1, IP : /10.12.2.206/10.12.2.206
Nom d'adresse IP virtuelle SCAN : scan2, IP : /10.12.2.207/10.12.2.207
Nom d'adresse IP virtuelle SCAN : scan3, IP : /10.12.2.208/10.12.2.208
this output looks like the output described in this document in ORACLE SUPPORT ID 975457.1
I read this whitepaper : http://www.oracle.com/technetwork/products/clustering/overview/scan-129069.pdf
And the output is more like this.
[root@<host> admin]$ srvctl config scan
Nom SCAN : <host>, rÃ©seau : 1/10.12.2.0/255.255.255.0/eth0
Nom d'adresse IP virtuelle SCAN : scan1, IP : /<host>.<domain>/10.12.2.206
Nom d'adresse IP virtuelle SCAN : scan2, IP : /<host>.<domain>/10.12.2.207
Nom d'adresse IP virtuelle SCAN : scan3, IP : /<host>.<domain>/10.12.2.208
Why is it different ? What does it means ?
Thanks for your help.

Hi, thanks for the quick answer !
I think my post is a little misleading. (i was too busy obfuscating)
In the first documentation it's the same adress twice
Nom d'adresse IP virtuelle SCAN : scan1, IP : /10.12.2.206/10.12.2.206
In the second documentation
Nom d'adresse IP virtuelle SCAN : scan1, IP : /<dns name for the adress scan>/10.12.2.206
I dont understand the meaning of this difference.

Srvctl config service should be updated using srvctl modify command

Hai all,
I have created a service recently on oracle RAC
srvctl config service -d dbname -s servicename
Disconnect: false
Service role: PRIMARY

What is Management policy? does AQ HA notifications should be true? Do i need to update the info in srvctl command, i have already entered in tnsnames.ora
(DESCRIPTION =
(LOAD_BALANCE = ON)
(FAILOVER = ON)
(ADDRESS = (PROTOCOL = TCP)(HOST =scan name)(PORT = 1527))

(SERVER = DEDICATED)
(SERVICE_NAME =servicename)
(FAILOVER_MODE =

(RETRIES = 0)
(DELAY = 0)
i have already have the basic, select for TAF in tnsnames.ora?But when i enter srvctl config command i don't see the config details,Do i need to modify using srvctl modify service command?
can anyone provide me a good document on services and explaining run time load balancing goal,Management policy,TAF ??

Srvctl config database won't show databases

by using
$ srvctl config database
I saw there is no result I expected. but I do have a couple of RAC databases are running, anywhere I missed to configure?
10.2.0.4 Rac AIX
thanks
Edited by: ROY123 on Nov 30, 2010 12:43 PM

by using below:
select name,network_name,creation_date,goal,dtp,AQ_HA_NOTIFICATION,clb_goal from v$services;
I can find out the service name in this RAC
I think the previous dba shoudl do below, to add database...(register):
The configuration should have been performed during the database creation, but it can be performed subsequently using the following commands.
srvctl add database -d ORCL -o /u01/app/oracle/product/10.1.0/db_1
srvctl add instance -d ORCL -i ORCL1 -n server01
srvctl add instance -d ORCL -i ORCL2 -n server02
srvctl add instance -d ORCL -i ORCL3 -n server03

Difference betwen srvctl relocate scan and scan_listener?

Hi all,
I have a 2 node RAC cluster using 11.2.0.2 Grid Infrastructure.
I am trying to get clear in my mind what the difference is between relocating the SCAN using srvctl relocate scan and SCAN_LISTENER using srvctl relocate scan_listener
Can anyone provide me with an explanation of when you would use each command and the effect it has?
Many thanks.

Hi,
see here for a closer explanation of SCAN:
http://www.oracle.com/technetwork/database/clustering/overview/scan-129069.pdf
Regarding your questions: The difference between a SCAN VIP and a normal RAC VIP, is that the RAC VIP has a node it want's to run on and each node has one (whereas you only have 3 SCANs). If it fails over to another node, the normal VIP exists, but does not accept connections, whereas the SCAN is not fix to a node and can run on any node in the cluster (and will accept connections anytime).
Now that this works, the SCAN VIP will always move with the SCAN listener (otherwise it would not make any sense). Hence there is really no difference in moving the SCAN VIP (because this will trigger a relocate of the listener) or to move the SCAN_Listener (since this will move the VIP it depends on).
Regards
Sebastian

How do I direct my HP 5510 e-all-in-one scan output to an Android tablet

How do I direct my HP 5510 e-all-in-one-printer scan output to an Android tablet? My printer is connected to my wireless network. During the printer setup I was able to identify both my desktop and laptop computers as "scan to" computers and they both appear as destinations on the printer display. I have been able to direct the printer scans to these two computers without problems. But I have not been able to find a way to direct the scan output to my Android tablet (Android Honeycomb 3.2.1). I have downloaded and use HP ePrint Home and Biz app and can print from the tablet. This app does not appear to offer a way to direct the printer scan output to be sent to the tablet. Any suggestions???
This question was solved.

Hi,
Currently, HP does not provide any scanning solution for Android OS.
Scanning from the front panel will allow you to scan to a computer only, and not to any mobile OS.
I would suggest you to search the Android Market for any 3rd party scan application, as the HP ePrint Home & Biz app currently provide scan capabilities for Apple iOS and Nokia Symbian as you may find listed below:

The scan output is a file with lines

The scan output is always a file with vertical lines. Whatever I try the printer, with wireless or USB connection, as well as scanning with HP scan or the App scan from Windows 8.1. The result is the same, ie, fuzzy lines.
Note: as a previous post suggested, I also open the lid and clean the glass.
I´m enclosing the output file:

Hi @TRuivo
I am sorry to see your scan output looks like a muddy rainbow I would be happy to do my best to help you with this!
Do you have the printer connected directly to a wall outlet or is it in a surge protector or power bar? Even if you have been using a surge protector/power bar all this time and you feel it is not the cause, please connect it to a wall outlet just so we can eliminate the power source as the root cause. Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector
In this document you will see, ISSUE: Problems or issues may arise when an HP LaserJet series printer is connected to an uninterruptible power supply (UPS), a power strip, or a surge protector
^ This is not limited to Laserjet printers.
Let's perform a hard reset. To do so, leave the printer on and unplug the power cable for 1 minute. While it is unplugged, hold down the power button on the printer for 10-15 seconds to release any built up power, then after the minute has passed, plug the printer back in.
Also, please download the latest firmware version to ensure your printer is up to date; DJ2540_188.exe
I hope one of these recommendations helps to resolve the issue!

Multiple String to search on the "Scan Output: Abnormal String" item

in the job definition on the run tab on the "option scan output: abnormal string" we use this command pipe to search for the string to force the job to get abnormal status. there are some case that when the job runs and the program being called throws error message other than the string "error". for example it throws "invalid" string to indicate the program has error out. is there a work around to include more than one strings on the commnad pipe? please adivse.
thanks,
warren

Just put a comma between the strings. If your strings contain spaces you need to put quotes around it. see below.
"Not connected","Login failed","File not found","The system cannot find the file specified","Access is denied","Unknown host","Invalid command"

HP6520 scan output problem

My scans are cut in half. Only one side of a letter-size document is showing up in the scan output. I've had this issue before and got chat help to fix it but can't find a way to reach that help again. Anyone else have this problem and know how to fix it or to get through this terrible "Support" system?

Hello MargaretSL,
Welcome to the HP Forums.
I see that you are having some scan quality issues with only half of the image showing up.
Does this happen when you do a regular copy or is it only when scanning to the computer?
One step that you can try is to please make sure that you have the printer power cable connected directly to a wall outlet and not a power bar/strip. Here is a document that uses a LaserJet printer as an example but it is meant for HP products in general. Please click on the following link that explains the Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector.
So I can better assist you, please respond with which Operating System you are running:
Which Windows Operating System am I running?
Mac OS X: How Do I Find Which Mac OS X Version Is on My Computer?
Please write me back when you have time and I will be happy to investigate into the issue further.

Scan output black

Installed OS X 10.9.2. Ever since have problems with Scan output of my Photosmat eStn C510. The scanned pages on the HP software tool look fine. When saving them to a file they come out black with some white lines. The alternative using Mac software does not work great...the HP software is more user friendly. Thxs

Hi,
Sorry you are gettign issues while saving your scans. What you seeing is a known issue with Mavericks and scanning. Until a complete resolution can be developed, using Image Capture will be the best work around.

Listener.ora file on RAC 11gR2 with SCAN

Hello,
I have 11.2.0.1 Rac with 2 nodes configured to work with SCAN.
The following listener.ora file was created during the rac installation.
(I only changed the name of the instance to XYZ in the output bellow).
There is only one listener.ora file for both the rdbms instance and the ASM instance.
Is it a good best practice or should i consider to create a seperate listener.ora
to the rdbms instance and to the ASM instance ?
The listener.ora is look as follow:
LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent
LISTENER_XYZ_=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_XYZ)))) # line added by Agent

Is it a good best practice or should i consider to create a seperate listener.ora to the rdbms instance and to the ASM instance ?No, you should not be creating separate listener for each Grid & DB. Listener is node specific resource. Oracle recommends in RAC environment the listener should be configured from GRID home and it will be able to serve both Grid and DB services.
It also helps in maintenance where as you can upgrade DB without bothering Listener, can have several db instances, and can have several versions of DB supported by a single listener.
I hope this answers your question. if yes please mark the question as answered and do not forget marking answer as a Correct answer.

RAC - srvctl problem

We have two node Windows Advanced server 2000 RAC setup.
srvctl command show status of the database on first node.
whereas it is not showing any output on second node.
Even though all the services are running properly.
Can you let us how to solve this problem.
Thanks in Advance
-Prashant

Hi
as per u error it means it will fail to communicate with other node in cluster,and i think cluster is not properly working.
Try a test:-
shutdown the first node and check whether this node(where gsdctl show error)
are able to perform recovery of fail node ,check alert log file and post it here.
also check log file
$ORACLE_HOME/srvm/log
Thanks and Regards

Any additional configuration require to achieve TAF in 11.2.0.4 RAC along with scan listener

Hi
We have 2 node RAC database of version 11.2.0.4 running on Linux platform.
There are 2 SCAN listener running on DB instead of 3 which usually recommenced by oracle.
When one of instance brought down as scheduled activity, sessions which connected to same instance, received ORA-03113: end-of-file on communication channel.
They were doing some select activity in db.
When user reconnected, it got connected to available instance.
tns entry which users are using (description=(address=(protocol=tcp)(host=p1bds1d4-scan.sldc.sbc.com)(port=1521))(connect_data=(server=dedicated)(service_name=p1bds1d4)))
Do we need to do any additional configuration to achieve TAF in 11.2.0.4 along with SCAN listener.
Do we need to change tns to include clause like "FAILOVER_MODE=(TYPE=SELECT)(METHOD=BASIC)(RETRIES=180)(DELAY=5)" ?
Please help.
Thanks
Ashish

You could enable TAF from the cient side by adding a clause such as that you suggest to your connect strings, but in a GI envirinment you would normally do it by adjusting the way the sevice is registered in the OCR. Run
srvctl modify service -h
and look up the -e and -m switches.

RAC nslookup of SCAN addresses

2 node RAC 11.2.0.2.0 on win 2008r2 64bit
what IPs should you see if you nslookup the nodes in a RAC? I have 2 RACs, dev and prod, Im getting different behaviour doing nslookup on the nodes. My networks say theres no difference in the config ( but Im not sure). The dev RAC is causing me problems which I think if I get can get this sorted will be ok. from my side, I built the 2 RACs the exact same so I cant see anything from the OS side.
Here is behaviour
Development RAC:
nslookup node1: I see (in any order as DNS is round robin)
physical ip node1
vip node1
scan1
scan2
nslookup node2: I see (in any order as DNS is round robin)
physical IP node2
VIP node2
scan3
Production RAC
nslookup node1: I see
physical ip
nslookup node2: I see
physical IP

the problem isnt really with with knowing where the SCAN is located and where any of the 3 addresses are or whether theyre up, its how they resolve in DNS.
With DNS set to roundrobin, its possible that one of the SCAN addresses can be first in the list if I nslookup the client name. If the SCAN 1 is on node 1 and relocated to node 2, then if I RDP to node 1 Im getting directed on to Node 2 as the IP is carrying over. Im thinking the arp issue with win 2008 is a culprit here, I have the oraarp driver running but it doesnt change the fact I see different DNS behaviour whether I nslookup in prod or dev.

Oracle 11gR2 RAC VM and SCAN and DNS and /etc/hosts (two) setup questions

Hi,
I am looking forward to setting up two Oracle 11gR2 RAC instances
on my Oracle VM test machine.
I plan on using the Oracle 11gR2 RAC VM template.
I want the final Oracle 11gR2 RAC instances to have SCAN that uses DNS.
The DNS will be pre-installed in the JeOS.
My first simple question about the setup is the following.
In my DNS name file, for example,
/var/named/chroot/var/named/milkyway.univ.db
do I need to provide the racnode1 and racnode2 information,
for example,
# DNS name file (snippet)
myjeos IN A 192.168.1.150
racnode1 IN A 192.168.1.161
racnode1-vip IN A 192.168.1.163
racnode2 IN A 192.168.1.162
racnode2-vip IN A 192.168.1.164
rac-scan IN A 192.168.1.131
rac-scan IN A 192.168.1.132
rac-scan IN A 192.168.1.133
Or, can I just provide only the rac-scan information
# DNS name file alternate (snippet)
myjeos IN A 192.168.1.150
rac-scan IN A 192.168.1.131
rac-scan IN A 192.168.1.132
rac-scan IN A 192.168.1.133
What I am getting at is the following.
Within the install process, will racnode1, racnode1-vip, racnode2,
and racnode2-vip host names and their IP address be written
to the RAC instances /etc/hosts files? (So I should not bother
to put them in the DNS name file like '# DNS name file alternate (snippet)'?)
Or, should I put the racnode and racnode-vip host names and IP addresses
in the DNS name file like '# DNS name file (snippet)'?
The second question is the following.
Are the cluster name and the scan name allowed to be different?
Currently, I would plan them to be different,
for example, rac-cluster and rac-scan.
Or, are they required to be the same,
for example, rac-cluster and rac-cluster.
Thank you.

AIM wrote:
do I need to provide the racnode1 and racnode2 information,

We write this data out to /etc/hosts just to reduce the amount of round-trip DNS requests the cluster nodes make for themselves.
Are the cluster name and the scan name allowed to be different?They can be different.
