Oracle RAC Issue

I have installed Oracle RAC on VM Ware . I am facing problem during database connection after shutting down any node . It takes 7-8 minutes for making new connection after any node down.
Please find below crs_stat -t output

One thing i noted that instance service is not running in crs_stat -t output .
After shutting down any node it give the error TNS-12514: TNS:listener does not currently know of service requested in connect descriptor . and it takes 7-8 for making any new connection.
Kindly suggest how i can resolve this issue.

Depending on how your service was created you may need to register it with CRS:
srvctl add service -d db_name -s service_nameCan you post your listener info? output from issuing lsnrctl status and also your tnsnames or connect string you are using to connect?
(be sure to change any sensitive data to something generic but make sure you change it in all places to keep it consistent)
Also if you use the direct IP address or hostname in your connect string instead of the SCAN does the slowness go away?

Linux Oracle RAC Issues with CRS

Using the Linux Oracle RAC install guide - I've finally installed my install on Linux for the Oracle RAC. Just one problem - now after 10 mins or so - one of my nodes loses communication which barks out a PRKH-1010 error after trying to run a status check on my nodes using the srvctl status nodeapps -n <servername> command.
any clues or ways to diagnose?

Hi!
The gsd relies on some files residing in /tmp/.oracle
Are they still there?
GSD is known to stop if they are absent.

Best oracle RAC book

can any one suggest me a best oracle book beyond documentation...
sure,
we can understand all the concepts through the documentation. have gone through clusterware administration and rac administration twice.
can any one tell me best book for troubleshooting basic oracle rac issues. and tuning the oracle rac. wait events etc.

Julian Dyke RAC books are considered to be among the best RAC available books:
Pro Oracle Database 10g Rac on Linux: Installation, Administration And Performance by Julian Dyke, S Shaw
Pro Oracle Database 11g Rac on Linux by Steve Shaw,Julian Dyke,Martin Bach
However these books are not specialized in RAC troubleshooting. For RAC 10g a very good RAC wait event documentation can be found in Oracle wait interface: a practical guide to performance diagnostics & tuning by Richmond Shee,Kirtikumar Deshpande,K. Gopalakrishnan.

RCA for Oracle RAC Performance Issue

Hi DBAs,
I have setup a 2 node Oracle RAC 10.2.0.3 on Linux 4.5 (64 bit) with 16 GB memory and 4 dual core CPUs each. The database is serving a web application but unfortunately the system is at its knees. The performance is terrible. The storage is a EMC SAN but ASM is not implemented with a fear to further degrade the performance or not to complicate the system further.
I am seeking the expert advises from some GURUs from this forums to formulate the action plan to do the root cause analysis to the system and database. Please advise me what tools I can use to gather the information about the Root Cause. AWR Report is not very helpful. The system stats with top, vmstat, iostat only show the high resource usage but difficult to find the reason. OEM has configured and very frequently report all kind of high wait events.
How I can use effectively find Network bottle necks (netstat command which need to be really helpful to understand).
How I can see the system I/O (iostats) which can provide me some useful information. I don't understand what sould be the baseline or optimal values to compare the I/O activities.
I am seeking help and advised to diagnose the issue. I also want to represent this issue as a case study.
Thanks

First of all, RAC is mainly suited for OLTP applications.
Secondly, if your application is unscalable (it doesn't use bind variables and no SQL statements have been tuned and/or it has been ported from Sukkelserver 200<whatever>) running it against RAC will make things worse.
Thirdly: RAC uses a chatty Interconnect. If you didn't configure the Interconnect properly,and/or are using slow Network cards (1 Gb is mandatory), and/or you are not using a 9k MTU on your 1 Gb NIC, this again will make things worse.
You can't install RAC 'out of the box'. It won't perform! PERIOD.
Fourthly: you might suffer from your 'application' connecting and disconnecting for every individual SQL statement and/or commit every individual INSERT or UPDATE.
You need to address this.
Using ADDM and/or AWR is compulsory for analysing the problem, and/or having read Cary Millsaps book on Optimizing Oracle performance is compulsory.
You won't come anywhere without AWR and OS statistics will not provide any clue.
Because, paraphrasing William Jefferson Clinton, former president of the US of A:
It's the application, stupid.
99 out of 100 cases. Trust me. All developers I know currently are 100 percent clueless.
That said, if you can't be bothered to post the top 5 AWR events, and you aren't up to using AWR reports, maybe you should hire a consultant who can.

SQLLoader issues of Oracle RAC with ASM

One of our client wants to use Oracle RAC with ASM for our application, i just want to know if there would be any two-phased commit transactions and SQL*Loader issues in ASM.
Database is Oracle 10g

ASM works only at storage layer and has nothing to do with:
- distributed transactions
- client executable that connects to database instance: SQL*Loader, SQL*Plus, etc.
RAC has also nothing to do with distributed transactions: a RAC database is a single database with multiple instances but still a single database; there is no need to use distributed transactions because you have a RAC database.

CC&B 2.1 on Oracle RAC 10.2.0 - any issues,tips,gotcha's

I am installing CC&B 2.1 on Oracle RAC 10.2.0.3. Is there anyone in the forum has experience of this and wants to share / compare notes. The architecture is 2 SUN M4000 servers (32gb RAM) for RAC with dataguard standby physical and logial. Application tier also unix with 4 T5440's each 32GB RAM where I will run minumum 3 instances per machine. The set up is in Test at the moment and I have only noticed one issue so far that is the threapoolworker keeps crashing. I have also had both nodes reboot at the same time as this issue and will raise an SR anyhow.
Any comments , tips , discussion welcome
cheers
Sam

Refer to Note: 887848.1, although it's for CC&B 2.2 and for some other DLL it should work in your case.
ID: 887848.1
The web server of CC&B 2.2 relies on the 32-bit Java platform to function.
The solution is to uninstall the JDK, and re-install the 32 bit versionOn other note, on x86_64 architecture the supported platform for Windows is Win2K8 Server SP2 (64-bit), I'd be reluctant to install CC&B on Vista.

Oracle RAC 9.2.0.7 and Weblogic BEA 8.1 sp5 known issues

Hi to all,
do you know if there are known bugs or issues about these versions of Oracle RAC and weblogic? I want to use these two versions but I want to know before if there are known issues, bugs or problems.
Thanks for everything.
F.

From an application server perspective the fact that a database is a RAC cluster is irrelevant. The app server is connecting to a service or an instance.
What is an issue potentially is RAC with 9.2 as you are missing the very substantive improvements brought forth in 10.2.

Oracle Rac 11GR2 installation issues;

Oracle RAC on Solarais Configuration Issue

Hi,
We are trying to install Oracle RAC 10g R2 on Solaris 10.
Following are the products
1=> Soalris 10 OS
2=> Sun Cluster 3.1
3=> Veritas Volume Manager
4=> Veritas Cluster File System
Can i deploy Oracle RAC using the above listed Software.
Here we have not purchase any of the Cluster Volume Manager.
Is the CVM required to install Oracle RAC.
Is there any alternative wherein we can install Oracle RAC without using CVM like for example using the RAW device where the VM will manage storage from a single node rather than buying the CVM that will allow to manage the storage from multiple nodes.
Also i would like to highlight is suggestion for using ASM is rule out hence ASM would not be used.
Can anyone suggest me some solution to the above problem.

Well, my impression is that you don't really know what your requirements are and you are trying to fit the technologies somehow. Worse yet, there is no clear understanding how those technologies fit together and as long as you explain what your vendor is saying you (which vendor?) they don't have clear idea either.
I would also suggest to review your decision to use Sun Network Data Replicator for DR site. Consider Oracle Physical Standby database instead - it's more flexible solution and doesn't limit your choice of storage stack.
1) Do Oracle RAC 10gR2 requires any Veritas Cluster Volume Manager
Words "any" and "Veritas" contradict in your question. But the answer is no. RAC require shared storage which can generally be one of those:
- raw devices with or without some kind of cluster volume manager
- cluster file system
- NAS storage (NFS mounted)
- ASM with raw devices for CRS files (OCR and voting disks)
2) Does Oracle RAC 10g R2 require any Vertias Cluster File System or it can sit on normal Vertias File System
Again, Oracle database files MUST reside on shared storage and non-clustered file system is not an option.
3) Is there any solution where we can use the Sun Cluster with Veritas Componets to configure RAC.
If I recall correctly, Sun Cluster includes in it's license some of component of Veritas storage stack. So you might be all set. You should turn to documentation on that stage and see exactly what you have licensed and if your stack allows shared storage. You might want to have a look at http://www.sun.com/software/whitepapers/solaris10/solaris_cluster.pdf
and Oracle Certification Matrix on Metalink.

In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?

In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?

The query is re-issued as a flashback query and the client process can continue to fetch from the cursor. This is described in the Net Services Administrators Guide, the section on Transparent Application Failover.

I had this problem and resolved it by transporting the file to the installation server with the correct ftp datatype (binary).
On page 54 of the install guide (..Server\Oracle_Business_Intelligence\doc\doc\bi.1013\b31765.pdf) that comes with the installation files, there is an instruction to make sure that any ftp activity is done in binary.
This may not have occured with the license.xml file if you use a tool which offers the "feature" of automatic datatype recognition.
Hope this helps.

Oracle RAC 11g on Windows 2008 64 bit - blue screen error on both nodes

Hi Everyone,
I installed Oracle RAC 11g on Windows 2008 64 bit, The installation was successfull and crs_state -t shows all services in two nodes are online.
When executed a select query with 100 sessions( For performance evaluation using Transaction generator ) ,the machine got crashed and blue screen is appeared on two nodes. I restrated the machines and and starts the same evaluation ,bt the same bug is repeating.
Can anyone suggest a solution to solve this issue? Is our hardware is not sufficient ? Shall we need to perform any
specific settings in Oracle RAC setup for performance evaluations?
Is our settings for load balancing is not enough? ( We added "Load Balancing= On" on tnsnames.ora on client for load
balancing)
The following machine configuration is used for Oracle RAC setup
Intel Core 2 Duo 2.66 GHz,
Ram :4GB.
OS : windows 2008 Server 64 Bit
Oracle RAC 11g , Clusterware 11g R2 , ASM with 5 raw disk ( 1- votting disk ,1- ocr files and 3 disk files)

Recommendations - Oracle RAC 10g on Solaris 10 Containers Logical/Local..

Dear Oracle Experts et all
I have a couple of questions for Oracle 10g RAC implementation on Solaris and seek your advice. we are attempting to implement oracle 10g RAC on Solaris OS and SPARC Platform.
1 We are wondering if Oracle 10g RAC could be implemented on Solaris Local/Logical Containers? I was assuming that Oracle will always link it self with OS binaries and Libraries while S/W installation and hence will need an OS image/Root Disk over which it could go. However, in containers, I assume we have a single solaris installation and configuration which will thus be shared to the containers which will be further configured in it. In such situations how does Oracle instalation proceed? Do I need to look at a scenario where, the global Container/Zone will have Oracle install and this image be shared across to zones/containers accordingly? If it is so, what all filesystems from OS will need to be shared across to these zones/containers?
Additionally, even if this approach is supported, is it a recommended approach? I am unsure about the stability and functionality of Oracle in such cases and am not able to completly conceptualize. However, I assume there could be certain items which needs to be approprietly taken care off. It will help if you could share observations from your experiences.
2 The idea of RAC we are looking at is to have multiple Oracle Installations on top of native clustering solution say veritas clusters/Sun Clusters. Do we still need to have Oracle Cluster solution Clusterware (ORACRS) on top of this to achieve Oracle Clustering? Will I be able to install Oracle as a standalone installation on top of native clustering solution say veritas clusters/Sun Clusters?
Our requirement is to have the above mentioned multiple Oracle installations spread across two (2) seperate H/W platforms,say Node A and Node B, and configure our Cluster Solution to behave as active-passive across Node A and Node B. In other words, I will configure Clustering Solution like VRTS/SunCluster in Active-Passive, then have 3 Oracle installations on Node A, another 3 on Node B. I will configure one database each for each of these Oracle S/W installation (with an idea not to have Clusterware between clustering solution VRTS/SunCluster and Oracle installation, if it works). Now I will run 3 databases thus on each of these nodes. If any downtime happens on any one of the nodes, say Node A, I will fail all oracle databases and S/W accordingly to the alternate available node, Node B in this case, using native clustering solution and I will want the database to behave as it was behaving earlier, on Node A. I am not sure though if I will be able to bring the database up on Node B when resources in OS perspective are failed over.
we want to use Oracle 10g RAC Release 2 EE on Solaris 10 OS latest/one before the latest release.
Please share your thoughts.

1 We are wondering if Oracle 10g RAC could be implemented on Solaris Local/Logical Containers? My understanding is that RAC in a Zone (Container) is not supported by Oracle, and will not work anyway. Regardless of installation, RAC needs to do cluster level stuff about the cluster configuration, changing network addresses dynamically, and sending guaranteed messages over the cluster interconnect. None of this stuff can be done in a Local Zone in Solaris, because Local Zones have fewer permissions that the Global Zone. This is part of the design of Solaris Zones, and nothing to do with how Oracle RAC itself works on them.
This is all down to the security model of Zones, and Local Zones lack the ability to do certain things, to stop them reconfiguring themselves and impacting other Zones. Hence RAC cannot do dynamic cluster reconfiguration in a Local Zone, such as changing virtual network addresses when a node fails.
My understanding is that RAC just cannot work in a Local Zone. This was certainly true 5 years ago (mid 2005), and was a result of the inherent design and implementation of Zones in Solaris. Things may have changed, so check the Solaris documentation, and check if Oracle RAC is supported in Local Zones. However, as I said, this limitation was inherent in the design of Zones, so I do not see how Sun could possibly have changed it so that RAC would work in a Local Zone.
To me, your only option is the Global Zone. Which pretty much destroys the argument for having Zones on a Solaris system, unless you can host other non-Oracle application on the other Zones.
2 The idea of RAC we are looking at is to have multiple Oracle Installations on top of native clustering solution say veritas clusters/Sun Clusters. Do we still need to have Oracle Cluster solution Clusterware (ORACRS) on top of this to achieve Oracle Clustering? Will I be able to install Oracle as a standalone installation on top of native clustering solution say veritas clusters/Sun Clusters?I am not sure the term 'native' is correct. All 'Cluster' software is low level, and has components that run within the operating system. Whether this is Sun Cluster, Veritas Cluster Server, or Oracle Clusterware. They are all as 'native' to Solaris as each other. They all perform the same function for Oracle RAC around Cluster management - which nodes are members of the cluster, heartbeats between nodes, reliable fast message delivery, etc.
You only need one piece of Cluster software. So pick one and use it. If you use the Sun or Veritas cluster products, then you do not need the Oracle Clusterware software. But I would use it, because it is free (included with RAC), is from Oracle themselves and so guaranteed to work, is fully supported, and is one less third party product to deal with. Having an all Oracle software stack makes things simpler and more reliable, as far as I am concerned. You can be sure that Oracle will have fully tested RAC on their own Clusterware, and be able to replicate any issues in their own support environments.
Officially the Sun and Veritas products will work and are supported. But when you get a problem with your Cluster environment, who are you going to call? You really want to avoid "finger pointing" when you have a problem, with each vendor blaming the cause of the problem on another vendor. Using an all Oracle stack is simpler, and ensures Oracle will "own" all your support problems.
Also future upgrades between versions will be simpler, as Oracle will release all their software together, and have tested it together. When using third party Cluster software, you have to wait for all vendors to release new versions of their own software, and then wait again while it is tested against all the different third party software that runs on it. I have heard of customers stuck on old versions of certain cluster products, who cannot upgrade because there are no compatible combinations in the support matrices between the cluster product and Oracle database versions.
I will configure Clustering Solution like VRTS/SunCluster in Active-Passive, then have 3 Oracle installations on Node A, another 3 on Node B. As I said before, these 3 Oracle installations will actually all be on the same Global Zone, because RAC will not go into Local Zones.

Reporting Services connections are getting dropped by Oracle RAC

My current customer is using Oracle RAC (11g) for their data store. They currently are using SQL Server Reporting Services to connect to it. We are experiencing an issue where the connection appears to be redirected at the server which causes the connection to be lost with the client.
I am curious if this is "by design" or if we need to review some configuration settings to better handle this.
We have 3 VIPs fronting the RAC and they are all specified in the TNSNAMES.ORA file.
Any feedback or input on this issue would be greatly appreciated.

Hi,
I suggest you look at:
http://www.oracle.com/technetwork/database/clustering/overview/awm11gr2-130711.pdf
and the similar paper from 11.1:
http://www.oracle.com/technetwork/database/clustering/overview/awmrac11g-133673.pdf
This explains the basic concept, of how clients should connect to the database, and probably clarifies your issue.
In generall Oracle will not redirect during runtime, only during connection time.
This however should not be of an issue, if you connect to a service. (You shouldn't connect to a SID since 8.1.7 anymore).

Sebastian

Oracle RAC Nodes getting reboot in case of preferred controller failed

When we are disconnecting both Fiber cable from preferred Controller A or plugging out Controller A card from Disk Array(IBM DS 4300), After 90 seconds both the servers are rebooting.
In this time complete RAC network is going out of service for approx 5 minutes.After reboot both servers are coming with both instances without any manual intervention
Its a critical issue for us because we are loosing High Availability, Let us know how we can resolve this critical issue.
Detail of Network:
1. Software- Oracle 10g Release2
2. OS- Redhat Linux 3 (Kernel Version-2.4.21-27.ELsmp)
3. Shared Storage- IBM DS 4300.
4. Multipathing Driver - RDAC (rdac-LINUX-09.00 A5.13)
4. Nodes- IBM 346
5. Databse on ASM
6. ASM,OCR & Voting Disk Preferred controller is A.
7. Hangcheck timer value is 210 seconds.
8. Both Server available with 2 HBA port . I HBA port is connected with Controller A and Seconfd HBA port is connected with Controller B of SAN Disk Array.
As per my understanding,
Voting disk resides in Disk Array and Controller A is preferred owner of Voting Disk LUN.. When i am disconnecting both fiber cable from preferred controller A , then Both Nodes Clusterware software trying to contact with Voting Disk, When they are unable to contact with Voting disk in specfic time period, they are going for reboot.
I tested Controller failure testing with Oracle RAC software as well without Oracle. Without Oracle its working fine and reason behind, in that time Disk Array is waiting for approx 300 seconds for changing preferred controlller from A to B.
But With Oracle, Clusterware Software reboot both nodes before Controller can shift from A to B.
So if i conclude,the tech who has good understanding of Oracle Clusterware on Linux OS & IBM RDAC multipath driver can help me.
when we install Oracle RAC on Linux, it is required to configure hangcheck timer.
Oracle recomends 180 second.
It means if one of node is hanging, then second node will wait for 180 seconds, if within 180 seconds ,it is not able to resolve this situation then it will reboot hung node.
I think Hangcheck timer configuration reuired only with Linux OS.
Configuration File
cat >> /etc/rc.d/rc.local << EOF
modprobe hangcheck-timer hangcheck_tick=15 hangcheck_margin=60

Sorry
Hangcheck timer is
Configuration File
cat >> /etc/rc.d/rc.local << EOF
modprobe hangcheck-timer hangcheck_tick=30 hangcheck_margin=180
