Problems on RAC

Hi,
I am having two node in my RAC application running on window server 2003 and of oracle version 10.2.01
My first node is Ntptaibdb01 which is currently handling the production load.
Issues is the server reboots itself not sure what may be the problem.
My second node is Ntptaibdb02 which is down.We had to shut it down because it was inpacting the node1's performance.Cluster on this node does not work and we are not able to start CRS,ASM and Instance.
Please give necessary steps to be checked down so that i can stop the server rebooting the nodes and make the second node up to so that it will work properly.
Thanks,
Binney

Hi Binney,
It sounds like your cluster is rather unwell; Node2's applications dont start, node 1 reboots itself, and when node2 is running node1 runs poorly? It sounds very unwell indeed.
Ok, first of all on node2 - CRS is the key app out of CRS/ASM/DB Instance Get that started and you are a long way forwards.
Check the Clusterwarealert log initially on both nodes - should be under $CRS_HOME/log/<servername>. Ths should give you info on why node1 reboots and why node2 doesnt start; or at least its the starting point. Errors in this file will refer you on to look at other logfiles specific to CSS,CRS.
Things to check on node2 (the one that doesnt start)
- Check the CR alertlog as above.
- Run CLUCFY on each node for "cluvfy stage -post crsinst " and report back what it says is wrong (if anything) for both nodes.
- Quick Check - Check that the server can see its shared storage locations for teh voting disks and crs.
- Quick Check - Check that node2 is indeed part of the cluster even if down by running "crs_stat -t -v" on node1 and checking to see that node2 is part of the cluster.

Problems with RAC and XA: Fallback

Hello,
we are seing problems with RAC and XA (Tuxedo 11, DB 11.2), specifically encountering "ORA-24798: cannot resume the distributed transaction branch on another instance".
The first scenario relates to fallback after a RAC node failure. There are two servers, S1 and S2. S1 makes an ATMI call to S2. Both servers are in the same Tuxedo group, using TMS_ORA. RAC is set up for failover (BASIC), no load balancing.
The sequence is:
- S1 and S2 are connected to the same RAC node n1. All is well.
- RAC node n1 fails. S1, S2 and the TMS_ORA all fail over to RAC node n2. After the failover has happened, all is well.
- RAC node n1 recovers. All is still well (as there is no automatic fallback).
- S1 (or S2) is restarted (either intentionally or because of a crash). Since n1 is up again, S1 connects to n1. Now we get ORA-24798. Permanently.
S1 is connected to n1 and S2 is connected to n2. Since both are in the same group, both use the same XA transaction branch. When called, S2 attempts to JOIN the transaction branch that S1 started. But the DB (11.2) does not allow the same branch to span more than one node. Hence the ORA-24798.
This seems to be a severe limitation in the combination of Tuxedo, XA and RAC. It basically means we still have to use DTP services, even with Tuxedo 11 and DB 11.2. Or are we missing something?
We could put S1 and S2 into different groups, but that seems to be inefficient, and not practical for a real application (10s of servers).
I am extrapolating from this that RAC load balancing would also not work, as S1 and S2 could be connected to different RAC nodes.
Roger

Roger,
When using an external transaction manager such as Tuxedo you should still declare Oracle services as DTP services when using Oracle Database 11g. The Tuxedo documentation is not clear about this. The relevant 11gR2 RAC documentation is at http://download.oracle.com/docs/cd/E11882_01/rac.112/e16795/hafeats.htm and states
"An XA transaction can span Oracle RAC instances by default, allowing any application that uses the Oracle XA library to take full advantage of the Oracle RAC environment to enhance the availability and scalability of the application.
"GTXn background processes support global (XA) transactions in an Oracle RAC environment. The GLOBAL_TXN_PROCESSES initialization parameter, which is set to 1 by default, specifies the initial number of GTXn background processes for each Oracle RAC instance. Use the default value for this parameter clusterwide to allow distributed transactions to span multiple Oracle RAC instances. Using the default value allows the units of work performed across these Oracle RAC instances to share resources and act as a single transaction (that is, the units of work are tightly coupled). It also allows 2PC requests to be sent to any node in the cluster.
"Before Release 11.1, the way to achieve tight coupling in Oracle RAC was to use Distributed Transaction Processing (DTP) services, that is, services whose cardinality (one) ensured that all tightly-coupled branches landed on the same instance—regardless of whether load balancing was enabled. Tightly coupled XA transactions no longer require the special type of singleton services to be deployed on Oracle RAC databases if the XA application does not join or resume XA transaction branches. XA transactions are transparently supported on Oracle RAC databases with any type of service configuration.
A"n external transaction manager, such as Oracle Services for Microsoft Transaction Server (OraMTS), coordinates DTP/XA transactions. However, an internal Oracle transaction manager coordinates distributed SQL transactions. Both DTP/XA and distributed SQL transactions must use the DTP service in Oracle RAC."
This issue came up earlier this year in another newsgroup thread at https://forums.oracle.com/forums/thread.jspa?threadID=2165803

Problems w/ race conditions when using attachmovie

Hello,
   I'm having a strange problem w/ race conditions when using attachmovie.
I have a class linked to a movie clip that I'm attaching to the stage.   The class is
fired off when the movie clip is attached but also other classes are getting loaded at the same time
while the movie clips is attached.     Even though the other classes are called after the
movieclip is attached, they are getting loaded faster and therefor the class linked to the attached movie clip
cannot access their functions.
I'm looking for a listener that will fire off an event ONLY when the attached movieclip is fully loaded but I can't
seem to find any examples of associating a listener to a attachmovie method.
Any ideas?
Thanks,
Clem C

flash is single threaded so nothing happens simultaneously. what do you mean by, "other classes are getting loaded at the same timewhile the movie clips is attached"

Performance problem of RAC

Dear,
I encountered performance problem in my production databases, running Oracle RAC (2 nodes) on version 10.2.0.2.0. The scenario is that the database suddenly slows down at a particular time. In reviewing the alert log, I found the following message:
Node 1: Ora-3136 inbound connection timed out (occurs around 20 times)
Node 2: SQL*net time-out error (occurs few times)
In addition, in my statspack report, at that particular time interval, the following messages appear:
Node 1:
For the top 5 timed events, 'log file switch completion' is the first on the list, with the following figures:
Waits Time(s) Avg Wait (ms) Total Call time
4143 4036 974 25.8
Node 2:
For the top 5 timed events, 'gc cr block busy' is the first on the list, with the following figures:
Waits Time(s) Avg Wait (ms) Total Call time
3387 1939 573 27.2
I just guess 'log file switch completion' should not always be on the 'wait list'. Also, Archive log seems not full at the moment. There are also a lot of I/O at that moment. Not understand what the DB is doing.
Do anyone have any ideas on the cause of the problem?
Thanks

You need to define a service to run preferably on node 2 with failover to node 1, and give a your batch jobs a connect string that connects to that service:
srvctl add service -d whatever -s batchserv -r node2 -a node1
and in your tnsnames.ora,
batchserv=
(description=
    (address_list=
         (failover=on)(load_balance=on)
         (address=(node1....)(address=(node2...))
     (connect_data=(service_name=batchserv))

Problems with RAC installation with Windows 2000 Advanced Server

Hello,
I've two servers in cluster mode with W2K Advanced Server, and a RAID-5 array of 4 disks shared by both of them. My problem is that I've installed The Cluster Service of Windows in order to have an active/passive configuration of my servers, because I have a common directory structure that is accessed by the PC's of the LAN.
By another hand, I want to install Oracle Real Application Cluster to manage my Oracle database but after create the extended partition and the logical drives when I execute the file \preinstallation_rac\clustersetup\clustersetup.exe to create the cluster, when I select the option Create a cluster the following error message appears me:
"Any disk Oracle partition has been found. Stop this wizard, create an Oracle partition and try it
again."
I'd like to know if it's possible to have the Service Cluster of Windows 2k and the Oracle clusterware?¿ Altough before begining the installation I've stopped my Cluster Service as documentation suggests. If somebody knows what it's happening to me I'd be really very grateful.
Thanks in advance,
Isabel

Hello Joel,
I've already read all documentation provided by Oracle about Real Application Clusters
and I've not found anything to solve my problem. Certainly I want to use OCFS but when I
try to execute preinstall_rac\clustersetup.exe to install CFS the error appear and I can't
continue with RAC installation.
Besides I've tried command "lsnodes -v" and got :
Could not load CM.dll
Could not initialize cluster
And when I've tried to run "clustercheck" I've got :
** Copy File: Create Directory failed - Error 183
** Directory = \\192.168.1.111\Cy$\Temp\opsm
Created directory \\192.168.1.112\Cy$\Temp\opsm
Could not copy file to other nodes [error = 183]
I've read metalink Note 186130.1 Clustercheck Fails with Windows Error 183 and the only
proof I haven't done is get the clustercheck.exe release1(9.0.1).
Any suggestion will be very appreciated.Thanks,
Isabel

Problem starting RAC database instance on Node 2

Thanks.

I don't know what your cron jobs do. If (for example) they logon to the database through a service published by the scan listeners, they will be happy. If they logon using a deterministic connect string, you have a problem - a problem caused by mis-using the system.

Tnsnames problem on RAC server for Different Host Names

Hi All,
We have RAC database setup and we are facing one issue on tnsnames.
My Hostfile has these entries:
127.0.0.1 loopback localhost
# Public Network
204.7.242.215 oradb1
204.7.242.217 oradb2
# Management network

204.7.242.216 oradb1-vip1
204.7.242.218 oradb2-vip2
# Rac HeartBeat
10.10.10.1 oradb1-priv1
10.10.10.2 oradb2-priv2
Where oradb1_mgt pointing to same host as oradb1 and oradb2_mgt>oradb2
Due to management issue, we need to use oradb1_mgt in place of oradb1 or oradb1-vip1 for standby database. So I've configured my Listener.ora as
LISTENER_ORADB1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = oradb1-vip1)(PORT = 1521)(IP = FIRST))
(ADDRESS = (PROTOCOL = TCP)(HOST = oradb1)(PORT = 1521)(IP = FIRST))
(ADDRESS = (PROTOCOL = TCP)(HOST = oradb1_mgt)(PORT = 1521)(IP = FIRST))
and Tnsnames.ora as
prd =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = oradb1_mgt)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = aixdb)
(INSTANCE_NAME = aixdb1)
But tnsping prd is giving error:
TNS Ping Utility for IBM/AIX RISC System/6000: Version 10.2.0.3.0 - Production on 07-JUN-2007 14:28:18

Used parameter files:
/u01/app/oracle/product/10.2.0/db_1/network/admin/sqlnet.ora
TNS-03505: Failed to resolve name
What may be the solution for this. Its look like that, HOST = oradb1_mgt is creating problem as if I'm putting HOST = oradb1 or OST = oradb1-vip1, then its working.

I have signed applets but not with jmf. Your best bet is to put the applet in a jar and sign the jar. Most java runtimes with a self signed applet will prompt the user and ask the user if they want to grant permission. You probably have to use the java html converter to code your html to force the use of suns plugin. I am not sure if you have to sign the jmf jars or they may already be signed.

Boot Problems (Fans Race)

I have a 20" 2007 2.0ghz C2D iMac that's refusing to boot, upon pressing the power button the fans race and nothing else happens. It will shut down if the power button is held for 5 seconds. If booted with no ram it doesn't beep, so it's not getting very far into the boot process.
So far I have confirmed (by testing in another iMac) that these components work:
hard drive - working iMac booted fine from this - s.m.a.r.t status was verified
ram - known to be working
CD drive - span up and read discs fine
LCD screen - worked fine
power supply - (just the circuit board - no cables) powered up the working iMac
This leads me to believe it's a problem with the logic board, however I tried the logic board from the working iMac (same age but 2.4Ghz) in the broken iMac, and even after a SMU reset it behaved in exactly the same way as before. That said, switching the suspect logic board into the working iMac didn't get much better results - the fans raced and it got stuck on a grey screen.
When booting the broken iMac (with it's own logic board) the first three lights come on the logic board light up, however the fourth doesn't - does this indicate something?
I don't really want to take this to be serviced as it'll cost more than it's worth spending, but does anyone have any ideas on what to try next?

Did it ever boot normally?
Until today, it had never boot abnormally.
Did you install any new software or memory just
before this started happening?
I installed some fonts last night... no new software immediately preceding this, however. Norton anti-virus, Microsoft Office, and a nightly WebKit build last week, but I've used it without problems since then.
Have you launched Disk Utility from your install disk
(located in the file menu) and Repaired Disk and
Repaired Permissions?
Not yet -- I was still in the denial / hopefull thinking phase of repair. Will do that and post back here either way. Thanks.

Disk Group problem in RAC

Hi,
I loosed a disk group in RAC (using ASM). It was empty, so it seemed not to be a problem. But, in fact, it had a vooting disk. I could managed database instances to start normally. Now I think I should use crsctl to delete such votedisk from crs and create a new one. (I already have a voting disk in another disk group).
But is it possible? All the examples I find in documentation are about moving or replacing voting disk information from one group to another....

Shared Server Connection Problem On Rac

Hii All
I configured dispatcher parameter in Rac environment as
"alter system set dispatchers='(address=(protocol=tcp)(host=node1-vip.domain.com))(dispatchers=10) (session=75)' scope=both sid='RAC1';
but when I run lsnrctl services I see vip ip address instead of node1-vip.domain.com so I have connection problems because Client trying to access to server via internet through Nat ip address and listener replies requests vip ip address so client can not connect the server.
I can acces to server on DEDICATED connection.
Have you idea ?

In document lsnrctl ouput shows host=node-vip But I cant see nor node1-vip.domain.com neither node2.domain.com just see node vip address That does not really matter - as the hostname is an alias for an IP address and as long as the hostname resolves to the correct IP address.
The issue (as I mentioned above) is that the external client needs to resolve these names to the NAT addresses. So what happens if you ping node1-vip.domain.com and node1-vip from the client? What happens when you telnet on the client to port 1521 and hosts node1-vip.domain.com or node1-vip ?
If this works and the client's Oracle connection does not, enable SQL*Net tracing on the client and look in the trace file for failed calls.
Also keep in mind that you would (by default) only have port 1521 NAT'ed. So should the client be redirected for a connection using a different port, it is unlikely that this port is NAT'ed - unless you're basically blindly NAT'ing all ports which would be unusual and risky.

Tablespace creation problem in rac

Oldbarrel wrote:
Billy, I'm just trying to understand why you posed the question "Do you run this via ASM as the volume manager for Oracle? Or do you use a cluster file system, direct raw devices or something else? " Can you clarify? Sorry. Did not phrase that question correctly. You can run ASM directly on the "raw/native" devices, or run it on devices managed by a disk volume manager. For example, you can use a disk volume manager to create a striped and mirror set of logical devices. You can then have ASM use these logical devices instead of the underlying "native" devices.
This impacts just who is responsible at the lower level of the I/O layer.
As you correctly pointed out, a CFS is not relevant here as an ASM diskgroup is used. Apologies for that foot-in-the-mouth comment. :-)
Async I/O on Windows (back when I was still doing Win32 s/w) was called overlapped I/O. And there were a couple of ways to deal with the completion part of the I/O. Do you have the kernel alert you (alertable I/O)? Do you actively wait (WaitForMultipleObjects) on async handles? Do you create a pool of threads to dequeue async I/O (GetQueuedCompletionStatus)? Each approach had its pros and cons.. and perhaps the OP is running into where the method used does not scale or work well for the underlying driver that does the actual I/O. (which makes me wonder just what method Oracle uses in this regard)

Information Storage PROBLEM with RAC

IÂ´m triing to install OCS information storage in RAC.
I have 2 servers already configured to install RAC(if i start the installer of a 9i 9.2.0.1.0 it recognizes the nodes). I already instaled the cluster manager and it is running. But the ocs information storage installer does'nt recognize it.
Could someone HELP me it is getting critical.
Thanks
Francisco

What else do you need? The error message seems to be quite clear.
Check the space left on the devices and possibly add more.
Maybe, the increase of SGA before lead to the try of swapping - which failed due to no space left.

I'm by no means a windows expert so I might be totally wrong here, but here goes.
You have to refer to the raw device by its name in the datafile clause. If you use a different name then the o/s can't find the device. Simple as that.
