RAC running with 3hrs gap among nodes

Hello Gurus,
We are in a very strange situtaion. We are running our system on 3 node RAC.The OS is RHEL 4 update 5 64 bit.The database is 10.2.0.4 with oracle clusterware.
The problem is that the the 3rd node has it's time set as 3 hrs ahead of first two nodes. The first two nodes are have difference of 3 minutes .The RAC was installed with first two nodes, 3rd node was added later.Our application is OLTP and does high DML operation.
Till date we haven't faced any problem . We discovered it just now.Now we are worried that what impact can it have on data consistency.
Could you please suggest what will be the impact and what procedure we should work on to correct it.
Thanks and regards,
jitender

I would recommend on node3.:
1. shutdown all the db instances
2. stop clusterware
3. fixup ntp and start it
4. make sure hangchek_reboot=1 and hangcheck_margin=10 in /etc/modprobe.conf for hangcheck-timer kernal module
5. modeprobe -v hangcheck-timer
6. start clusterware
7. start db instances

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.

Oracle RAC with more then two nodes?

Hello,
knows anybody a reference client project that use Oracle RAC with more then two nodes on a Linux environment?
Many thnaks!
Norman Bock

Hello Norman,
XioTech is a SAN company that has a project called "THE TENS". They configured and ran a 10 node RH Linux Oralce 9i RAC. I understand they want to see if 32 are possible. I am sure if you ask them, they would be happy to give you the details.

EBS 12.1.3 RAC to RAC Cloning with Shared Appl_Top

BismillahirRehmanirRahim
Dear All,
I need to Clone our Production EBS Environment from RAC to RAC with Shared APPL_TOP and Multi Tier Appl Tiers.
We have EBS 12.1.3 Environment with 2 Appl Tier Nodes with Shared Appl_Top & EBS DB is on 11gR2 RAC 11..2.0.4.
I am following Doc IDs 406982.1 & 559518.1.
But its not clear which directories need to be copy and restore for Shared Appl top on each Node.
Also what Steps will need to be executed on Each Nodes and
What Steps need to be executed only on one Node.
Appreciate your feedback.
P.S.
Kindly share if anyone have Step by Step Doc for RAC to RAC EBS Cloning.

Hi Hussein,
thanks for the reply.
+The path is different (first path is db while the second one is apps), so copy the file from the source instance to $COMMON_TOP/clone/context/apps directory on the target instance and try then -- Troubleshooting RapidClone issues with Oracle Applications R12 [ID 603104.1]+
What I meant to say that CTXORIG.xml already exists in the correct directory in the target system:
$COMMON_TOP/clone/context/apps
Anyways, I recopied the file from source to the target system $COMMON_TOP/clone/context/apps, but still the same problem. I'll continue reading "Troubleshooting RapidClone issues with Oracle Applications R12 [ID 603104.1]".
I noticed below when running "perl adcfgclone.pl appsTier" with perl debug mode:
Cwd::_backtick_pwd(<10.1.3 ORACLE_HOME>/perl/lib/5.8.3/aix-thread-multi/Cwd.pm:204):
204: local @ENV{qw(PATH IFS CDPATH ENV BASH_ENV)};

Cwd::_backtick_pwd(<10.1.3 ORACLE_HOME>/perl/lib/5.8.3/aix-thread-multi/Cwd.pm:205):
205: my $cwd = `$pwd_cmd`;
DB<1> s
pwd: No such file or directory

Not able to connect to RAC Database with VIP entries

Hi All,
My RAC database run with Physical Host entries in listener and tnsnames files.
But VIP services are running in both nodes.
Now i want to use VIP enties to connect to the RAC database from client side.
I have modified the both the listener and tnsnames files with VIP entries and bounced the instance.But It didn't work.
Please suggest what could be done in this issues.

Hi,
It is 10.2.0.3 and remote_listener is set to LISTENER_Hostname and Remote listener is configured.

I am upgrading to Calendar Server 4.0 on NT with more than 9 nodes (or I already have) and my server won't start

I am upgrading to Calendar Server 4.0 on NT with more than 9 nodes
(or I already have) and my server won't start.
<P>
The steps are the same whether you have already upgraded or are about to.
<P>
Calendar Server 4.0 on the Windows NT platform can only support up to nine
nodes on one server, while 3.51 supported up to 14. If you have a Calendar
Server 3.51 with more than 9 nodes that you want to upgrade to Calendar Server
4.0, Netscape recommends that you migrate the extra nodes to another Calendar
Server 3.51 on another Windows NT system. To accomplish this:
<OL>
<LI>Install Calendar Server on another Windows NT machine and configure it to
use the same directory server as your current Calendar Server.
<LI>Stop and backup your current Calendar Server.
<LI>Individually zip up the node directories you want to move to the new
server. (drive:\unsers\unison\db\Nx
where "x" is the number of the node you want to use.)
<LI>Stop the new Calendar Server.
<LI>Unzip the files into the new Calendar Server in the same place as they
were on the old server.
<LI>Edit the unison.ini
file on the new server to add the nodes you have just migrated.
<LI>Edit the unison.ini
file on the old server to remove the nodes you have moved to the new server.
<LI>Edit the nodes.ini
file on the old server to remove the nodes you just moved and then add them
with the new hostname. Keep in mind that you will only be able to modify the
node network from the old host.
<LI>Run unidbfix -export
on both servers for all nodes.
<LI>Edit the remotenodes.ini
file on both servers to reflect your node topology.
<LI>Run unidbfix -import
to import the changes into the node databases.
<LI>Run unidbfix -c,
then -f,
then -c
again on both servers for all the nodes.
<LI>If you don't get any errors, run uninode -test all
to test if your nodes connections are set properly. If they are not, <B>do not</B>
start either of the servers; instead, fix the errors and try again.
<LI>Start both servers.
<LI>Log in and check to see if you can see people on remote nodes.
<LI>Notify the users on the moved nodes of their new calendar host.
<LI>If you did this in preparation of an upgrade, you can now run the upgrade to
4.0 since both servers contain fewer than 9 nodes.
</OL>

Oracle 11gR2 RAC installation with DNS

Dear Guru's,
I want to configure RAC on two node cluster with DNS(For SCAN) in my testing server.
O.S: RHEL5.4(64 bit)
Oracle Version: 11gR2(11.2.0.2)
Note: Am creating nodes in VMware ESXi server.
Just I want to know whether DNS should be configure in any one of those NODES or in separate machine.
Bala :)

Hi Bala,
I want to configure my Database with & without DNS. (Will try both installation in different servers)I think, you have already received a link on very good article about Oracle RAC installation without DNS and DHCP (I mean Jeffrey Hunter's article).
There is one more about Oracle RAC installation with DNS and DHCP (http://gjilevski.com/2011/10/05/build-two-node-oracle-rac-11gr2-11-2-0-3-with-gns-dns-dhcp-and-haip/).
And want to know how it forwards the client connection if a node fails.. Can anyone update the URL for this..There are a lot of information about it:
- http://www.oracle.com/technetwork/database/features/oci/taf-10-133239.pdf

Race conditions with UI thread

Hi community,
the update to LabVIEW 2014 has caused sveral of my vis to act up - vis that I had coded with race conditions with the UI thread that I was not aware of.
Maybe they didn't exist previously, maybe I was just ignorant.
Here is a where I first noticed something was wrong. It has a workaround inside:
http://forums.ni.com/t5/LabVIEW/How-to-make-sure-plots-in-xy-graph-are-present/td-p/3033109
Thanks again Norbert for your help with that.
Now problems are showing up in other places too and it might be the tip of an iceberg. I'm a little afraid right now. It's not just xy graphs. The latest example:
I have a sub-vi whose frontpanel I open with an invoke node inside that sub-vi. Afterwards, in the caller I register for events of frontpanel objects of the sub-vi. This fails now - apparently the fp of the sub-vi isn't open yet although the sub-vi has finished executing (yes, I use dataflow to ensure register for event is done only after the sub-vi has finished). This has a striking resemblance to my issue in the previous thread. It seems that vis can now be "finished" executing while stuff that was supposed to happen inside the sub-vi is still executing in the UI thread.
I had not expected this.
Is this intended behaviour?
Is this new to LabVIEW 2014?
Can someone please shed some light on this behavior change (if indeed it is one)?
Can someone please advise me on a general solution/workaround for the host of problems this is causing me?
Best regards
Florian

Norbert,
I'm currently unable to reproduce the issue in my code regardless of cpu core affinity (you gotta hate random errors).
I have attached an example that shows a simplified version of the code that has previously produced the error.
This example might be flawed since it hasn't produced the error yet.
The issue would show when the button "open window" is pressed, if it did at all.
Also there is stuff in there that I just implemented in an attempt to keep the UI thread busy.
For the core of the issue please disregard the bottom while loop in caller.vi
I'll keep trying.
Best regards
Florian

Cluster design with subscriber 10.X on VM to exisiting MCS 7835I running with v8.6

Hi
At present CUCM is running with single node MCS 7835I (v8.6) in cluster. Now planning to implement cluster by building subscriber with version 10.X on VM to existing MCS 7835I which remains as publisher.
Does cluster support dissimilar hardware and software mismatch setup ?
Also having plans to upgrade MCS H7835I to 9.1 later, is it possible ?
Thanks in advance

Thanks aton Jaime Valencia & Aman Soi
Now I understood. Publisher and subscriber in a cluster should have same version.
Here is the hardware details
MCS7835I3-K9-CMD2
HW Platform      : 7835I3
Processors      : 1
Type                : Intel(R) Xeon(R) CPU       (E5504 @ 2.00GHz)
CPU Speed         : 2000

Oracle RAC One with SAP?

Hello,
are there any plans to release RAC One with SAP?
Will it be included in the general Oracle RAC 11.2 release for SAP?
Who can tell me the (list) price for Oracle RAC One for SAP systems?
The note 527843 doesn't help with any of these questions.
Regards,
Mark

Hello,
I am especially interested in the licence policy of RAC One.
Will it be part of standard or extended licence ???
Generally RAC One is an Oracle Option that just limits the RAC with 2 nodes.
If SAP makes certification for "RAC" generally and not for "RAC One" this would be
no technical reason.
If somebody authorized can answer my question this would be great.
Best Regards
Andreas

Subroutine execution priority with Call By Reference nodes

Hi -
I have a VI which contains a Call By Reference node. I would like this VI to run with subroutine execution priority (the VI is small, is called frequently, and must run quickly). The VI being called by reference is itself set to run with subroutine execution priority. However, I get an error which reads: subroutine priority VI cannot contain an asynchronous node. What is asynchronous about a call-by-reference to another subroutine VI? Is there any way to get around this? Thanks.
Jason
Jason Rolfe

This is what the help files mention:
Subroutine priority VI cannot contain an asynchronous node
This VI has subroutine priority selected in the Execution page of the VI Properties dialog box. It cannot use an asynchronous node on its block diagram. Asynchronous nodes, such as dialog boxes, are supposed to allow other VIs on the same thread to continue to execute while they wait to complete their own execution. However, subroutine priority VIs block the execution of other VIs on the same thread until the subroutine priority VIs finish execution.
You can correct this error in the following ways:
Change the execution priority of this VI. To change the priority, right-click the VI icon in the upper-right corner of the front panel or block diagram window, and select VI Properties from the shortcut menu to display the VI Properties dialog box. Select Execution from the top pull-down menu of the VI Properties dialog box, and change the priority in the Priority pull-down menu.
Remove the asynchronous node.
I am affraid that the call by reference node is asynchronous.

Tmloadcf cannot run on a non-master node

Hi Rafik,
You don't mention what type of machine you are using, but if it is Microsoft Windows
the OS has an annoying habit of displaying all but the first letter of the name
in lower case letters, even if it was entered in upper case letters. Tuxedo is
case sensitive in this respect - the easiest way to check is to right-click on
"My Computer", select Properties, then select Computer Name. The Full computer
name will show the correct case of the name as it was entered, and this is what
you must use with Tuxedo.
Regards, Malcolm.

Step by Step RAC 11GR2 with Grid Infrastructure on Solaris installation

Y'ello All,
Please I need documentation for RAC 11GR2 with Grid Infrastructure on Solaris installation urgently.
Thany you very much for your support
BR,

What type of shared storage will you be using?
Properly configure DNS
Properly configure /etc/hosts files
Properly configure SCAN
Properly configure SHARED storage (Preferably ASM - "raw" devices) - make sure you partition the disk devices to "skip" the first 1MB of the device)
BEFORE installation, confirm grid-owner and oracle-rdbms-owner can read AND write to these shared devices from ALL nodes. Permissions must be set to <grid-owner:<grid+oracle shared group> (grid:oinstall where oracle is also in the oinstall group)
Properly configure ssh password-less connections for both GRID-owner AND oracle-rdbms-owner.
IP addresses required
3 SCAN addresses that point to myhost-scan.mydomain.tld in a round-robin fashion
PER NODE:
1 public IP address
1 virtual IP address
1 interconnect IP address should be iin /etc/hosts ONLY - Non-routable and not reachable via the public interface. DO NOT use CROSSOVER cable.
Interconnect should be on a DEDICATED INTERCONNECT switch.
As for the SHARED storage, the LUNS/Devices can be "carved" out on your SAN by your SAN admin. MAKE SURE that ALL devices in a given diskgroup are EQUAL size. (ie - DATA000=250GB/each, DATA001 500GB/each etc)
The installation guide gives a lot of directions on PRE-REQUISITES. Follow them. And remember, since you are new to this, you may install this several times before you get it the way you need it to be. Even installing MANY RAC clusters on multiple platforms, I still install it 2-3 times. Generally because the SA has forgotten some pre-req step.
