Oracle High Availability Training

I am seeking training on High-Availability Oracle solutions - Not just Parallel server, but Standby, and HA configuration in Sun Clustered environments. The training should focus on the RDBMS (8i/9i).
Any recommendations for Oracle or Third-Party training classes would be appreciated.
I understand that Oracle alone will provide high reliability but to get to .9995 reliability (not 5 9s) we'll need some sort of high-availability solution.
Thank You for your time.

Hi
Check with Oracle University for High Availability classes. I
had an opportunity to look at their new features papers and they
were very good

Oracle high availability service is showing as down in em 12c

Hi,
I thought I could use some help from here before going to oracle.
Can you please share your ideas what might went wrong
EM 12c is showing oracle high availability service as down though it is up and running.

CRS-4638: Oracle High Availability Services is online

Hello,
We are not performing any system maintenence today so I'm not sure why you were presented with a message stating that. Can you share you support request # (SR#) so I can look into your case and follow with you offline?
Whenever we perform maintenence where you'll be unable to use a feature of the service notification should be provided on our status page.

CRS-4639: Could not contact Oracle High Availability Services

Hi Everyone,
I have installed 11gR2 GRID and RAC on RHEL 6.
With the installation when I ran the root.sh script I had to run the following command for the HAS to be able to start successfully:
/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1 (According to MOS: 1069182.1)I have duplicated a database onto this environment and after a reboot of the servers the HAS does not start.
None of the logs get updated to give/show any information except 1,$GRID_HOME/log/node1/client/css.log, which gives:
2011-02-03 13:17:41.480: [ CSSCLNT][1441978112]clssscConnect: gipc request failed with 29 (0x13)
2011-02-03 13:17:41.481: [ CSSCLNT][1441978112]clsssInitNative: connect failed, rc 29I checked and tried everything according to MOS: How to Troubleshoot Grid Infrastructure Startup Issues [ID 1050908.1], but to no avail.
If I run the command
/bin/dd if=/var/tmp/.oracle/npohasd of=/dev/null bs=1024 count=1 (According to MOS: 1069182.1)and then manually start HAS everything starts perfect.
Is there any way to bypass this or get a permanent solution?
Thanks in advance.

HI!
In RHEL 6 inittab is no longer supported, it uses upstart insted.
See more info in page:http://searchenterpriselinux.techtarget.com/tip/RHEL-6-ditches-System-V-init-for-Upstart-What-Linux-admins-need-to-know
To solve the issue do the following:
Create the file:/etc/init/init-oracle.conf
*#start oracle*
start on runlevel [0123456]
stop on runlevel [016]
respawn
exec /etc/init.d/init.ohasd run >/dev/null 2>&1 </dev/null
After the file is created, reboot and Oracle should start normaly

After start of Grid High Availability Service (HAS) can't umount filesystem

I have weird problem when I start and stop HAS. File system get's into state, where it does not umount. So filesystem where grid software is running can't be umounted on boot. 9Is there something I do wrong, or don't do right.
I have fresh install of latest 64-bit UEK2 kernel (2.6.39-400.109.1.el6uek.x86) and Oracle 11.2.0.3 Grid Infrastructure for standalone server. I Installed patch p12983005 (112036_Linux-x86-64) to get ACFS support for kernel. When I start HAS and ASM, file system does not umount anymore. Here's steps. Example is from local disk, but I have same problem with LUN from SAN. I thought it might have something to do with SAN and multipath, but SAN is not to blame cos same happens with local disk. Don't know why local disk seem be mapped by multipath in fstab.
1. Mount fs
[root@SERVER ~]# mount -t ext4 /dev/mapper/vg_SERVER-lv_app /u01
2. Start HAS
[grid@SERVER ~]$ crsctl start has
CRS-4123: Oracle High Availability Services has been started.
3. Stop HAS
[grid@SERVER ~]$ crsctl stop has
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'SERVER'
CRS-2673: Attempting to stop 'ora.cssd' on 'SERVER'
CRS-2673: Attempting to stop 'ora.LISTENER.lsnr' on 'SERVER'
CRS-2677: Stop of 'ora.cssd' on 'SERVER' succeeded
CRS-2677: Stop of 'ora.LISTENER.lsnr' on 'SERVER' succeeded
CRS-2673: Attempting to stop 'ora.evmd' on 'SERVER'
CRS-2677: Stop of 'ora.evmd' on 'SERVER' succeeded
CRS-2793: Shutdown of Oracle High Availability Services-managed resources on 'SERVER' has completed
CRS-4133: Oracle High Availability Services has been stopped.
4. Try umount
[root@SERVER ~]# umount /u01
umount: /u01: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
[root@SERVER ~]# fuser /u01
[root@SERVER ~]# lsof |grep /u01
Neither of fuser or lsof returns nothing.
This and the fact that ACFS cannon't be mounted on boot, get's me wondering should I use ASM and Oracle Restart at all at this point. Initial reason is that in future this is likely going to be part of RAC.

I followed the instructions and copied the edid file I obtained while monitor was connected directly to the specified directory.
Now I get:
Jan 17 13:14:09 daniel-think kernel: platform VGA-1: Direct firmware load for edid/medion-edid.bin failed with error -2
Jan 17 13:14:09 daniel-think kernel: [drm:edid_load] *ERROR* Requesting EDID firmware "edid/medion-edid.bin" failed (err=-2)

High availability for AS forms & Reports

Hi,
i like to know the best solution for high availability of Oracle Application Server(10g) Forms & Reports Services ...as load balancing is not done for forms & reports with the oracle high availability solution( i guess i am rite).any suggestions
thanks
mish

Well, install Oracle AS Forms and Reports on two different nodes and configure your Forms and Reports services on both of them. Use a virtual host configuration to load balance (by hardware load balancer) to both hosts which are the resources. Use the webcache (standalone or the one that came with the install) to map the virtual host to the resources on the two hosts. Use REPORTS_SERVERMAP to map the name of the 'cluster' reports server to the local reports server, ie REPORTS_SERVERMAP=app:app1 on node 1 and REPORTS_SERVERMAP=app:app2 on node 2. Use REPORTS_SERVERMAP=app:app1;appl:appl1 to add more applications/reportservers. Set REPORTS_SERVERMAP in O_H/forms/servers/default.env and the application env files and under O_H/reports/conf/rwservlet.properties.

Oracle University has seats available for Oracle Policy Modeling training

This is highly recommended training for everyone working with Oracle Policy Modeling. Two part virtual classroom "essentials" series with currently scheduled dates including:
Essentials Part 1: Feb 7, May 23, May 29
Essentials Part 2: Feb 15, May 30, June 5

Hi Arpit
Thanks for your interest and sorry to hear about your payment problems. Unfortunately Oracle has different payment policies for different countries, and online payment is not available everywhere.
Oracle University has scheduled the two courses to run again in the same timeslot from 7-11 June 2011. If there is sufficient demand, then I can request that they schedule the courses to run again sooner than that.
How many people is Evosys looking to send, and where are they based?

Oracle Berkeley DB Java Edition High Availability (White Paper)

Hi all,
I've just read Oracle Berkeley DB Java Edition High Availability White Paper
http://www.oracle.com/technetwork/database/berkeleydb/berkeleydb-je-ha-whitepaper-132079.pdf
In section "Time Consistency Policy" (Page 18) it is written:
"Setting a lag period that is too small, given the load and available hardware resources, could result in
frequent timeout exceptions and reduce a replica's availability for read operations. It could also increase
the latency associated with read requests, as the replica makes the read transaction wait so that it can
catch up in the replication stream."
Can you tell me why those read operations will not be taken by the master ?
Why will we have frequent timeout ?
Why should read transaction wait instead of being redirect to the master ?
Why should it reduce replica's availability for read operations ?
Thanks

Please post this question on the Berkeley DB Java Edition (BDB JE) forum Berkeley DB Java Edition. This is the Berkeley DB Core (BDB) forum.
Thanks,
Andrei

Oracle EBS R12.1.3 High Availability with RAC 11g on VMWARE

Dear All,
Our customer requirement is of high availability and good utilization of hardware for EBS R12.13 implementation.As per our strategy we want to use Oracle VM(I think it doesn't require any licensing) , RAC 11gR2 and appstier load balancing.We have only two servers to achieve all these.One one node there will be two VMs one for dbtier and another one for appstier and same will be on second server.So this way we will be having four virtual machines on two physical nodes.For all these we will use OEL Linux as Operating system
Please share your experiences , if above deployment model is correct or need further enhancements.
Regards.

Oracle Linux High Availability (HA)

We would like to employ High Availability (HA) on Oracle Linux in order to provide solid service. How can we achieve this? What software do we need to install and where to start? We want HA not only for middle tier but all kind of software running on the server.

If you cannot make a decision based on technical aspects, perhaps it will help to make a decision considering other aspects:
- what product or service are you trying to provide?
- what is your technical background?
- what is your budget?
- what are you planning for the future?
I have not seen any useful general review or comparison of cluster products and there are several major players on the market. The situation is obviously complex and the right product depends on the product or service you are planning to provide. If you are ever thinking about using an Oracle database product, it would be foolish not to go for Oracle Clusterware.
I think you should also very much consider virtualization and HA. Again, if you are planning to provide Oracle services, Oracle VM Server for x86 might be your best option, which is also a free product and designed for a production environment.
In my humble opinion, Oracle products are generally complex and not necessarily the most admin or user-friendly solutions, but you will find a lot of support and as far as I'm aware, no other product will provide you a better cost of ownership than Oracle Linux and Oracle VM Server, which is zero.

Oracle Version - High Availability Installation

Hi,
We are shortly to install SAP on Windows2008/Oracle.
The DEV and TEST systems are to be installed as stand alone Centralised installations.
The LIVE system is to be installed as a High Availability system, clustered over two hosts.
I have questions surrounding the Oracle Editions:
Looking at the differences between the two Oracle editions in respect to our requirements, Enterprise supports fail-over, whereas Standard does not.
So,
Does an SAP high availability installation require Oracle Enterprise Edition to be installed or can it be Oracle Standard Edition?
Does SAP's High Availability installation functionality handle the complete failover, regardless of Oracle Version?
Thanks in advance for your assistance.
Chris

> Does an SAP high availability installation require Oracle Enterprise Edition to be installed or can it be Oracle Standard Edition?
SAP systems (also for test and QA) always require Oracle Enterprise edition. You may get it technically to work with the standard edition but it's not supported:
Note 105047 - Support for Oracle functions in the SAP environment
<...>
56. Standard Edition
* SAP products always require the Oracle Enterprise edition, using Oracle Standard edition is not permitted.

Oracle reports 10g High Availability

Clustering is deprecated with 10g application servers and High availability is recommended by Oracle for fail over of Report services (standalone).
I would like to get any incite , oracle references as to how the recommended solution could be implemented both for cold and hot fail over of report services within the same subnet.
the architecture of our environment is that two hosts (one of them being standby) run report services using namingservice discovery mechanism and requests are manually redirected to the standby service in case one of them fails.
how could this be transformed into hot fail over ?
Regards

Read the section on High Availabilty in the Publishing Reports to the Web manual, and the section on Reports in the High Availability Guide.

Oracle Identity Federation - High Availability

Hello,
We are trying to figure out the high availability options supported by the Oracle Identity Federation. While reading the documentation we find it a bit confusing. We read the OIF Administrator Guide here: http://download.oracle.com/docs/cd/E10773_01/doc/oim.1014/b25355/advtopics.htm#CHDBCDFG
In Section "9.4 High Availability" it said that "Oracle Identity Federation supports the Cold Failover Cluster (CFC) or active-passive high availability configuration,". In the Application Server 10g guide also said the same and explicitly said that the active-active configuration is not supported for the OIF.
Then in Section "9.5 Setting Up a Load Balancer with Oracle Identity Federation" it explains how to set up a load balancer for the OIF. When it explains this it says that we can have several instances of OIF in different machines, configured with a load balancer. All these instances share the same transient database where the sessions are stored.
Which is the difference between this load-balancer-based configuration and an active-active high availability configuration? If one node of the load-balancer configuration goes down, the sessions administered by him are lost? That is the difference?
Thanks!
Leonardo

Hi
I am not very sure about High Availability configuration but for Load balancer as mentioned in the document, You have to have both the instances sharing transient database where sessions will be stored.
If both the OIF instances are not sharing transient database and you have LB sharing load, It will not work as sessions will be store in memory. So sessions from one OIF instance will not be known and available to the other instance of OIF.
Thanks

High availability when using Oracle Service Bus as Middleware?

Hi there,
We are designing a new solution here which will be composed of SAP WM, Middleware and a Java application.
We have been using OSB when sending data from Java to SAP, and we can get many "channels" working. So we get higher throughput and also HA.
Now, in that new project we will need to send data from SAP to a Java application, but some people told me we can't have more than one channel when sending data from SAP to OSB. I mean, we won't be able to have High Availability unless we use SAP PI. The only option we would have is to set the gateway to broadcast the message to all available channels, which would duplicate the messages got by the Java application.
Is that true? Is there any alternative for using OSB with SAP and still get HA and High throughput (SAP -> OSB).
What do you guys think?
Regards

anyone?
Please
