Oracle 10g RAC query fails

Hi,
I am a newbie to RAC implementations, I have a strange problem on the one we are testing,
Failure (forced shutdown) of one of the nodes results in queries on the other node returning with a ORA-12805. This happens only in certain cases, otherwise the query waits for some time and completes. We are using Redhat 3, Oracle 10g (10.2.0.1.0) and TAF with SELECT and PRECONNECT options. Is there some reason and remedy on why this fails on only one of the nodes ?.

Hi
From metalink
ORA-12805
=========
Error Summary
ORA 12805 parallel query server died unexpectedly (Oerr:ORA.12805)
Error Details
~~~~~~~~~~~~~
Error: ORA 12805
Text: parallel query server died unexpectedly
Cause: The PMON process is cleaning up the process because a parallel query
server terminated unexpectedly.
Action: Check for operating system errors and retry the statement.
If this problem persists, contact customer support.
When a ORA-12805 occurs in most cases you will also see another error, ORA-600 or
a ORA-7445.
Best thing for you to do is to check all logs (that may include alert, crs, css etc) and determine the cause of node crash.

Oracle 10g RAC installation on HP-UX 11.31 for SAP ERP 6.04

Dear experts,
We are trying to install SAP ERP 6.0 EHP4 with Oracle 10g RAC on HP-UX 11.31. Please note that, We are using VERITAS cluster filesystem (CFS) for this purpose and not HP-UX ServiceGuard ClusterFileSystem.
*As per SAP procedure, we have installaed plain plain SAP system with single instance Oracle (ref: Configuration of SAP NetWeaver for Oracle Database 10gRAC guide). Now we are first trying to install Oracle Clusterware (CRS) and then we will install Oracle RAC software. Is this procedure right?*
Which file (and its path) we have to use for CRS installation and its patch? Is it runInstaller under /oracle/stage/102_64/clusterware? With this file we can install CRS 10.2.0.1. Similarly for Oracle RAC, which files we are supposed to use, i.e for installation and patch upgrade?
Also can we use clusterware package available from Oracle directly in the SAP environment?
We tried to install CRS with runInstaller while running Configuration Assistant after root.sh script.
The following commands are failing in Configuration Assistant:
/oracle/CRS/102_64/bin/racgons add_config erpprdd1:4948 erpprdd2:4948
/oracle/CRS/102_64/bin/oifcfg setif -global lan1/20.20.20.0:cluster_interconnect lan0/192.168.3.0:public
/oracle/CRS/102_64/bin/cluvfy stage -post crsinst -n erpprdd1,erpprdd2
1st command does not give any output if run manually.
2nd commands o/p: PRIF-12: failed to initialize cluster support services
3rd commands fails in every check
Please suggest the solution and expecting answers to the above mentioned questions.
Thanks & Regards,
Tejas

You can go for combined os migration and db release upgrade also at a stretch with the same downtime.

Those errors remind me on errors I encountered when I was trying to do installation that was not certified,
so try to check if installation you are doing is actually supported.
In the meantime , visit metalink and read document [ID 460969.1] , */usr/bin/ld: Cannot Find -lxml10, Genclntsh: Failed To Link Libclntsh.so.10.1*

Hi all,
I have a question about Oracle RAC and network interface.
We're using Oracle 10gR2 RAC with two nodes on Linux Red Hat.
Let's assume that the public network interface goes down.
I would like to know what happens with existing connections
on node with network interface with problems.
Are connections frozen, actives?
Can the users continue to use theses existing connections using the another node of RAC?If the interface is down? what do you think? All connections to this node will die. How does your application handle fail-over, does it attempt to reconnect or just have a complete application failure?
You should spend some time in a test lab where you can test this stuff for yourself. Read the documentation and there are tons of sites out there that purport to have all of your RAC/TAF/FAN/FAF questions. - I would read and trust the documentation first.

I know that the listener goes down and any other connections is allowed.
Thank you very much!!!!

You know its not certified?
My first thought when I read the subject of this thread, and before reading what you posted, is that you've either done no research on RAC or didn't understand what you've read.
You can create a RAC cluster using any operating system certified by Oracle.
But the operating system is the least important part of creating a cluster. The questions you need to be able to address are:
1. What is your solution to created shared storage?
2. What is your solution to create the cache fusion interconnect and VIPs?
If you don't have an answer to these questions you can not build a RAC cluster.

Problem with Oracle 10g RAC VIP network setting at Solaris 9

Dear All,
I have tried to set up a Oracle 10g RAC Release 2.
With OS solaris 9, and 2 nodes.
The nodes setting as the following:
nodes 1:
Public address: 172.16.0.121
Private address: 192.168.0.121, 192.168.1.121 (dual path for heart beat)
nodes 2:
Public address: 172.16.0.122
Private address: 192.168.0.122, 192.168.1.122
And i have assigned two IP adress 172.16.0.131, 172.16.0.132 as the VIP address for the
RAC.
And the following is the /etc/hosts file:
root@shk01 # cat /etc/hosts
# Internet host table
127.0.0.1 localhost
# public address
172.16.0.121 shk01 loghost
172.16.0.122 shk02
# heart beat
192.168.0.121 shk01-priv1
192.168.1.121 shk01-priv2
192.168.0.122 shk02-priv1
192.168.1.122 shk02-priv2
# VIP address
172.16.1.131 vip-shk01
172.16.1.132 vip-shk02
But when i run the command "$ ./runcluvfy.sh comp nodecon -n shk01,shk02 -verbose"
it shows the error:
ERROR:
Could not find a suitable set of interfaces for VIPs.
Result: Node connectivity check failed.
I did try to add the VIP address on bge0:1, as i using bge0 for the public address.
Both nodes i did using the same interface name for it.
Anyone have idea for me to check out the error?
Also, I have other question about the raw device.
As there is option for setting for ASM or raw device. If choosing raw device, does it mean that it just need to
format the storage disk but without newfs it? And then the Oracle program will able to handle it?
Thanks,
Xentar

You don't seem to state categorically that you are using Solaris Cluster, so I'll assume it since this is mainly a forum about Solaris Cluster (and IMHO, Solaris Cluster with Clusterware is better than Clusterware on its own).
Clusterware has to see the same device names from all cluster nodes. This is why Solaris Cluster (SC) is a positive benefit over Clusterware because SC provides an automatically managed, consistent name space. Clusterware on its own forces you to manage either the symbolic links (or worse mknods) to create a consistent namespace!
So, given the SC consistent namespace you simple add the raw devices into the ASM configuration, i.e. /dev/did/rdsk/dXsY. If you are using Solaris Volume Manager, you would use /dev/md/<setname>/rdsk/dXXX and if you were using CVM/VxVM you would use /dev/vx/rdsk/<dg_name>/<dev_name>.
Of course, if you genuinely are using Clusterware on its own, then you have somewhat of a management issue! ... time to think about installing SC?

How to maintain Data availability in Oracle 10g RAC when LOADING the data?

Hi
we are having Oracle 10g server on Sun Solaris(64 bit) with 8 GB RAM.
We are in need of moving the database to "Oracle 10g RAC". (Real Application Clusters)
Our doubt is when loading the data into RAC server, will it affect the application?
coz' we heared that RAC server should be down when we load the data.
Is this correct?
If yes, then How to maintain High data availability when we load the data in RAC server?? Please help me.
Thanks.

First, is this the same question that a colleague of yours posted in this thread?
Data Load in RAC
Second, are other sessions querying the table that you're loading data into? If so, how are you loading the data?

Installation of oracle 10g rac on open solaris for X86 Machine

Hi
Can you please let me know the advantages of installation of oracle 10g rac on open solaris on x86 machine.And also let me know the detail steps involved in instatllation of oracle 10g rac on open solaris on x86. please suggest the recommdendation for the installation
Thanks
Saiprasath

If by "advantages of installation of oracle 10g rac on open solaris on x86 machine" you mean advantages over RAC on Linux or AIX or HP/UX there aren't any.
If you want to know the advantages of RAC over stand-alone they generally relate to:
1. Eliminating the server as a single point of failure
2. Transparent fail-over
2. Incremental horizontal scalability

Max Connections to Oracle 10g RAC Instance

Hi,
We have IBM Websphere Application Server on one unix server which is connecting to a Oracle 10g RAC Instance which is on a different unix server through JDBC connection. They(Application Team) are doing stress tests, please tell me how many connections can a Oracle Database Allow simultaneously. They tested for 2000 connections simultaneously. It failed...This is urgent, they are on call please reply ASAP
Thanks,

Use Oracle Shared Server (the default is Dedicated Server),
I've shown JBOSS app developers how a little Dell desktop (256MB RAM, 1.7Ghz P4) can accept a 1000 app server connections (using Shared Server). While a big HP-UX server failed to accept 200 connections (using Dedicated Server).
Oracle RAC should easily be able to handle 100+ concurrent client OLTP connections per RAC node using Shared Server - assuming that each of the concurrent sessions are actually doing stuff and not just sitting there idle. (if 99.99% of the connections are idle, then even a little desktop Oracle database can handle well over a 1000)
Bottomline - you must have your primary focus and expertise on Oracle. On the the data tier. Not the app tier. The data tier is what scales the app tier. Not vice versa. Adding an extra app tier server does not enable the data tier platform to suddenly be able to run more SQLs, The app tier does not scale the data tier.
If you want performance and scalability, you must get the data tier right. App tier be damned as that is neither here nor there ito performance and scalability. This means Oracle expertise is required first and foremost.

Oracle 10g RAC

Hi All,
I am a research student currently struggling to install Oracle 10g RAC on Windows OS.What i understand about a Oracle RAC database system is that it involves a configuration of multiple hosts or servers joined together with a clustering software and accessing the shared disk structures.What i also understand is that i need a CRS provided by Oracle for a Windows or Linux based RAC installation.
What i don't understand is for a Two node RAC system do i need a Third machine which has the shared storage device.If yes do i have to install a copy of Oracle 10g Enterprise Edition and CRS on the shared storage device moreover do i need to install a copy of Oracle 10g Enterprise edition on each of the nodes or just the clusterware is enough.

Hi Salil
No, you do not need a third machine. You can even setup RAC as a single node on one machine! What you do need is to have some sort of cluster aware file system. Try looking at OCFS on Windows in your case.
If you are interested in a Linux example please have a look at the examples at http://ocpdba.net/oracle9i_rac/cheaprac.html and http://ocpdba.net/oracle10g_rac for an OCFS implementation I am working on.

Oracle 10g RAC using ASM - Storage Issue

I’ve an issue related to Oracle 10g RAC.
I’ve 2 node cluster each being Dell 2850 Server with RHEL 4.0
I’ve EMC CX300 SAN storage with following partitions
/orasoft     10 Gb          OCFS2 File system
/oracrs          2 Gb          OCFS2 File system
/orabackup      100 Gb          OCFS2 File system
The datafiles are on ASM which is not directly visible in OS.
I’ve common Oracle Home installed in /orasoft/db_1 which is shared by both nodes in cluster.
I’ve faced an issue recently related to EMC storage.
The /orasoft partition displays 1.4 Gb space available using df command.
With both nodes sharing the common Oracle Home (/orasoft/db_1), when ever I try to touch a file I get an error as No Space left on device. I’m unable to start any service with the same reason.
Is this setup correct ??
Can anyone help me with this storage issue ??

Need a clarification here...what do you mean by "Storage System"...do you mean a server/node or the SAN storage system. If you are referring to a server/node's local storage, then it would NOT be possible for use by RAC, since the disk space has to be shared among the nodes.
Here is what you can do:
- Create two partitions/devices (for example Disk_1 and Disk_2) in the SAN storage
- Create a ASM disk group which would mirror Disk_1 to Disk_2.
Again, please note that the partitions have to be visible and be accessible read/write from both the nodes/servers.

Thanks

Hi,
If you create a new diskgroup you may be to add the same diskgroup to parameter file or spfile and which will be needing down time.
sugestion: Instead of creating new diskgroup you should to add disk to existing group.if you add asm disk to existing group your all problem will be solved and Oracle itself will be managing all.And than i am sure no need to add entry in the parameter or spfile like +db_create_file_dest=.....

Using Clob with TopLink 9.0.4.5 and Oracle 10g RAC

I am trying to store an XML file in a Clob type field of a DB table using TopLink 9.0.4.5 and Oracle 10g RAC and need some guidance about how to do it. I got some directions to start it with the Tip "How-To: Map Large Objects (LOBs) to Oracle Databases with OracleAS TopLink" but still need some more helps.
When using the Oracle JDBC OCI driver, the tip gives the code block for a Clob field:
DirectToField scriptMapping = new DirectToField();
scriptMapping.setAttributeName("script");
scriptMapping.setFieldName("IMAGE.SCRIPT");
descriptor.addMapping(scriptMapping);
As I understand, TopLink creates instances of the Descriptor class at run time for each of the descriptor files and stores them in a database session, where is the proper place (in SessionEvent of TopLinkSessionEventHandler?) for me to get a reference to such an instance of my Descriptor class in Java code so that I can add the above mentioned additional Mapping? Are the above String values of "script" and "IMAGE.SCRIPT" predefined in TopLink API? Can I accomplish the same thing just using the TopLink Workbench tool instead? If yes, please advise the detailed steps to do so.
The tip also states to call the following code in case of using Clob:
DatabaseLogin login = session.getLogin();
login.useStringBinding();
Should the above 2 lines of code be called after the following lines of code?
SessionManager sessionManager = SessionManager.getManager();
Server serverSession = (Server)sessionManager.getSession("MY_SESSION_NAME");
Besides the above extra coding for the Session and Descriptor Mapping, is there any special handling in between Data model and DB table mapping? Can I map a Java String type to a DB Clob field using the Direct-to-field mapping?
Appreciate any help.

Never mind ....... I had already figured it out .....
