RAC course with Oracle

I went to the Oracle RAC Clusterware course 11gR2, Oracle training set up the Oracle RAC with 2 VMs inside 1 machine for students to learn.
I have only 1 server, I want to set up like that, then I can learn it.
Does anybody know how to set up like this ?

The proper way would be to setup DNS (or GNS) but you can get away with putting three IP addresses with the same scan hostname in /etc/hosts on each node for a lab environment if you don't have access to a DNS server or simply don't bother. That should not be a solution for a production system but will be ok for a lab setup

Problem to create database with RAC 10g with Oracle Standard Edition

I install CRS (Cluster Ready Services), and then install Oracle 10g database. Also, I install patches 10.1.0.4. When I create database with ASM storage give me a error to create files database.
Any idea?
Thanks

Training suggestions for RAC course

I would like to take a training course in Oracle Real Application Clusters. I previously took a 10g Admin I course with Oracle University in NYC, and it was okay, but the cost was quite high: $3000 USD for five days. They also offer a RAC course, but this is even more expensive: $3750 for five days!
I'd like to know of any quality alternatives in the United States, especially at a lower cost. I've found a few courses that seem to be good, but they cater to larger groups and on-site training.
Perhaps this isn't the best venue for such a question, but I hope that Oracle will understand someone in my position, looking for quality training at a reasonable cost.
Thanks in advance for your suggestions.

Thanks, all, for your helpful comments.
Trubix seemed promising, but they haven't posted a new course in almost a year.
TUSC also seems promising. They're next scheduled RAC course is in July of this year.
Also found what looks like a good tutorial on RAC via VMware here:
http://www.oracle-base.com/articles/10g/OracleDB10gR2RACInstallationOnCentos4UsingVMware.php
Please let me know of any others that are as good or better.
I read that Oracle permits only their own courses for "hands-on credit" toward certification, but I'm not sure what that means, as I thought you needed only to pass their test to be certified. Is this true?
Thanks again.

What are the important points during a Linux upgrade with Oracle database?

Is there a specific document or metalink note that I may follow similar to this one during a Linux os upgrade -
http://download.oracle.com/docs/cd/B28359_01/server.111/b28300/toc.htm
Lets talk on an example; we may talk on upgrading details of a RHEL3 RAC system with Oracle options used like ASM,OCFS etc. to RHEL4. What steps are important to take by order and what are the best practices to be careful about during this type of an os upgrade for Oracle?
Best regards.

may I need to get support from https://linux.oracle.com/pls/apex/f?p=101 for this kind of a documentation?

Solaris x86 with Oracle RAC 10g Enterprise Edition Release 10.2.0.3.0

Hello,
Maybe you can help me (new on RMAN backup) in doing this.
I have configured a single Oracle 10g database to have backup with RMAN with following steps:
1. $ mkdir $ORACLE_BASE/rman_scripts
2. $ mkdir $ORACLE_BASE/logs
3. $ mkdir $ORACLE_BASE/tracking
4. $ mkdir $ORACLE_BASE/c_backup
5. $ sqlplus sys/<password> as sysdba
6. SQL> alter system set db_recovery_file_dest_size = 50G scope=both;
7. SQL> alter system set db_recovery_file_dest='${ ORACLE_BASE}/flash_recovery_ area' scope=both;
8. SQL> alter system set log_archive_dest_10='location= use_db_recovery_file_dest';
9. SQL> shutdown immediate
10. SQL> startup nomount
11. SQL> alter database archivelog;
12. SQL> alter database open;
13. SQL> alter database enable block change tracking using file '${ORACLE_BASE}/tracking/rman_ change_track.f';
14. $ rman target /
15. RMAN> CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK
TO '/var/opt/oracle/flash_ recovery_area/ORCL/c_backup/% F';
16. RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
17. RMAN> CONFIGURE BACKUP OPTIMIZATION ON;
18. RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
19. RMAN> exit
I need to configure incremental backup with RMAN on a two node Solaris x86 with Oracle RAC 10g Enterprise Edition Release 10.2.0.3.0 installation.
We also use ASM to store database files, and have Oracle software installed on separate file systems (two Oracle roots for Node1 and Node2).
I have following questions:
1) where to put Flash Recovery Area (FRA)?
I saw recommendations to put FRA on the ASM, is this the best way to do it?
2) Can I put FRA on another file system (not on the ASM) which is available only from Node1? This way I can save space on the ASM.
3) Is it possible/recommended to run RMAN from Node1 only?
Below is the script used to run RMAN on the normal Oracle database (without RAC) which I need to change :
=============================================================================================
2.0 Oracle backup script: /opt/app/oracle/rman_scripts/backup.sh
Use this for daily backups, possiblly as a cron job.
Once a week run this: /opt/app/oracle/rman_scripts/backup.sh FULL
All other days of the week: /opt/app/oracle/rman_scripts/backup.sh INCREMENTAL
Note: You may have to change ORACLE_SID, ORACLE_BASE below to match your database.
=============================================================================================
#!/usr/bin/ksh
ORACLE_SID=orcl
ORACLE_BASE=/opt/app/oracle
ORACLE_HOME=${ORACLE_BASE}/product/10.2.0/db_1
PATH=${ORACLE_HOME}/bin:/usr/bin
LOGDIR=${ORACLE_BASE}/logs
LOGFILE=${LOGDIR}/rman.log
if [[ $# < 1 ]]
then
echo "usage: backup.sh FULL|INCREMENTAL"
exit;
fi
BACKUPTYPE=${1}
full='FULL'
incremental='INCREMENTAL'
if [[ $BACKUPTYPE == $full ]]
then
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup database;
SQL 'alter system archive log current';
backup archivelog all;
delete noprompt obsolete;
exit;
eof
echo ''
fi
if [[ $BACKUPTYPE == $incremental ]]
then
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup database;
backup incremental level 1 database;
SQL 'alter system archive log current';
backup archivelog all;
delete noprompt obsolete;
exit;
eof
echo ''
fi

Hi [email protected],
Q1) where to put Flash Recovery Area (FRA)?
A1) With RAC: on the shared storage
I saw recommendations to put FRA on the ASM, is this the best way to do it?
If you want your backups to be available for both nodes you have to use shared storage or tape using an mml library.
So if you want to use the FRA for rman backups and the database is on ASM just make ASM the standard for the FRA as well.
Q2) Can I put FRA on another file system (not on the ASM) which is available only from Node1? This way I can save space on the ASM.
A2) Than you cannot recover in case Node1 is down. Best would be to send your storage admin to a training course so he can manage the clustered raw devices needed for ASM.
Q3) Is it possible/recommended to run RMAN from Node1 only?
A3) No see A2.

Tycho

Oracle 10g RAC design with ASM and OCFS

Hi all,
I have a question about a proposed Oracle 10g Release 2 RAC design for a 2 node cluster.
ASM can store database files but not Oracle binaries nor OCR and voting disk. As such, OCFS version 1 does not support a shared Oracle Home. We plan to use OCFS version 2 with ASM version 2 on Red Hat Linux Enteprrise Server 4 with Oracle 10g Release 2 (10.2.0.1).
For OCFS v2, a shared Oracle home and shared OCR and voting disk are supported. My question is does the following proposed architecture make sense for OCFS v2 with ASM v2 on Red Hat Linux 4?
Oracle 10g Release 2 on Red Hat Enterprise Linux Server 4:
OCFS V2:
- shared Oracle home and binaries
- shared OCR and vdisk files
- CRS software shared OCFS v2 filesystem
- spfile
- controlfiles
- tnsnames.ora
ASM v2 with ASMLib v2:
Proposed ASM disk groups:
- data_dg for application data
- backupdg for flashback and archivelogs
- undo_rac1dg ASM diskgroup for undo tablespace for racnode1
- undo_rac2dg ASM diskgroup for undo tablespace for racnode2
- redo_rac1dg ASM diskgroup to hold redo logs for racnode1
- redo_rac2dg ASM diskgroup to hold redo logs for racnode2
- temp1dg temp tablespace for racnode1
- temp2dg temp tablespace for racnode2
Does this sound like a good initial design?
Ben Prusinski, Senior DBA

OK Tim, thanks for advices.
I think Netbackup can be integrated with RMAN but I don't want to loose time on this (political).
To summarize:
ORACLE_HOME and CRS_HOME on each node (RAID1 and NTFS)
Shared storage:
Disk1 and disk 2: RAID1: - Raw partition 1 for OCR
- Raw partition 2 for VotingDisk
- OCFS for FLASH_RECOVERY_AREA
Disk3, disk4 and disk5: RAID 0 - Raw with ASM redundancy normal 1 diskgroup for database files.
This is a running project here, will start testing the design on VMware and then go for production setup.

ALBPM 5.7 BPM process admin issues with Oracle 11g RAC as directory service

Hi,
Setup ALBPM 5.7 enterprise for weblogic.
BPM Engine deployed on weblogic cluster.
BPM process admin (web console) deployed on tomcat.
BPM process admin uses WEB-INF/directory.properties for directory configuration.
things were fine with oracle SID,
directory.default.url=oracle://<db_host>:1521/schema=diruser,sid=BPMDB { with this, login to process admin was working fine}
But clueless, on how to configure RAC as the directory service in the above directory.properties file. Since this is a old version, no directory.xml in the installation.
Connection string:
(DESCRIPTION =
(LOAD_BALANCE = on)
(FAILOVER = on)
(ADDRESS = (PROTOCOL = TCP)(HOST = DB_HOST1)(PORT=1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = DB_HOST2)(PORT=1521))
(CONNECT_DATA =
(SERVICE_NAME = BPMDB)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
Please help how to use service name (above connection string) in directory.properties, to be able to login to process admin successfully.
Thanks in advance,
Swamy

Using admin center, able to get the string to be used in directory.properties.
FYI, the string looks like below,
directory.default.url=oracle://customURL:0/schema=bpmdirectory,customURL=jdbc:oracle:thin:@(DESCRIPTION = (LOAD_BALANCE = on)(FAILOVER = on)(ADDRESS = (PROTOCOL = TCP)(HOST = DB_HOST1)(PORT=1521))(ADDRESS = (PROTOCOL = TCP)(HOST = DB_HOST2)(PORT=1521)) (CONNECT_DATA = (SERVICE_NAME = BPMDB.DOMAIN.COM) (FAILOVER_MODE = (TYPE = SELECT) (METHOD = BASIC))))

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:

Does /sapmnt need in cluster file system(SAP ECC 6.0 with oracle RAC)

We are going to be installing SAP with Oracle 10.2.0.4 RAC on Linux SuSE 10 and OCFS2. The Oracle RAC documentation states:
You must store the following components in the cluster file system when you use RAC
in the SAP environment:
- Oracle Clusterware (CRS) Home
- Oracle RDBMS Home
- SAP Home (also /sapmnt)
- Voting Disks
- OCR
- Database
What I want to ask is if I really need put SAP Home(also /sapmnt) on cluster file system? I will build a two nodes oracel 10g RAC and I also have another two nodes to install SAP CI and DI. My orginial think is sapmnt is a NFS share, and mount to all four nodes(RAC node and CI/DI), and all oracle stuff was on OCFS2(only two rac nodes are OCFS), anybody can tell me if SAP Home(also /sapmnt) can be NFS mount not OCFS2, thanks.
Best regards,
Peter

Hi Peter,
I don't think you need to keep /sapmnt in ocfs2 . Reason any file system need to be in cluster is,in RAC environment, data stored in the cache of one Oracle instance to be accessed by any other instance by transferring it across the private network and preserves data integrity and cache coherency by transmitting locking and other synchronization information across cluster nodes.
AS this applies to redo files, datafiles and control files only , you should be fine with nfs mount of /sapmnt sharing across and not having ocfs2.

Using Tuxedo with Oracle Real Application Clusters (RAC)

Hi all ,
Our present Producation environment is Tuxedo8.0 with Oracle 9i as database .
We are planning to implement oracle RAC .
Can any one tell us , with the current tuxedo version which is 8.0 ,can we for RAC Or we need to upgrade Tuxedo to 9.1 for RAC Implementation?
If anyone has Implemented Tuxedo and Oracle with RAC successfully
Pls share your experience.
Thanks In Adavance
Nadeer .

Subbu,
As I mentioned earlier in this thread, support for Oracle RAC has been
implemented in Tuxedo 9.1 and in the Tuxedo 8.1 and Tuxedo 9.0 rolling patch
streams. There are no plans to backport this feature to Tuxedo 8.0. If you
plan to use RAC transactionally and if it is possible for multiple services
that could be located on different RAC instances to be accessed in a single
transaction (which will be true for most applications), then you should
upgrade to a version of Tuxedo with support for Oracle RAC. The
documentation at http://e-docs.bea.com/tuxedo/tux91/ads/adorac.htm#248431
gives an overview of RAC support in Tuxedo.

Hello Nadeer, Hello Ed,
Has the implementation of Tuxedo8.0 with Oracle RAC was completed
successfully ?.
If it is done , I have few doubts. Could you please help me ?.
1) I hope your Tuxedo middleware connects to the oracle Database using
Oracle XA resource manager and the TMS server built using buildtms with
oracle as RM .As per the mail from Ed, migration of Tuxedo9.1 should be done
before moving to Oracle RAC.
Also from BEA documentation, Oracle RAC support was given as new feature in
Tuxedo9.1.
Our Application uses Oracle RM to connect to Oracle DB[ Oracle 10g] from
Tuxedo8.0. So do we need to upgrade to Tuxedo9.1. for using Oracle RAC ?.
Thanks for your help

Sun Fire V490 x 2 servers with Oracle RAC facing Split brain problem

Hi all,
I have Sun Fire V490 x 2 servers with Oracle RAC and they faced a Split brain problem. One of the node's database instance has gone down, The DBA claims it is due to network problem, but as such the networks are OK. We use the on board CE1 interface for Cluster interconnect and CE0 as the public interface.
Did anybody face this kind of a problem? Could this be a hardware/OS patch problem?
I had kept a continuous ping for 24 hours after this happened last time and the output shows no packet loss
Many thanks in advance.
Ushas Symon

In order to diagnose this properly, you'll need to provide too much detail and far too many log files for a generic discussion forum to handle.
Use your service contract and open a support case.
Because a cluster environment is involved you'll likely end up talking to the cluster support staff.
They can analyze hardware and software errors as well as review whether you configured the systems in a supportable fashion.
Be prepared to make a direct connection to each system and gather data using such as by using the Explorer tool. The technical support staff will tell you what they will actually need.

what is dead locks with oracle and wht is race condition wrt oracle

> And do you know what a race condition is all about?
It is a term used to indicate several processes attempting to use the same resource that is not capable of servicing all these at the same time. This could be due to the resource not being thread safe or implemented as a serialised resource.
It is often easy to look up definitions on Google. In the Google search field, type "define:race condition".

SAP ECC6.0 installation with Oracle RAC

Hi Expert,
Current we working on SAP ECC6.0 installation with Oracle 10G RAC on AIX 5.3. The RAC are running on two nodes (servers). And we are using GPFS filesystem (not running on HACMP).
Overall we had completed the Oracle RAC installation (CRS+RDBMS) and tested the oracle failover and it work find. Now we want to start with the SAP installation (with HA). In the SAP installation documentation, it did request to create a virtual hostname on the node and execute the sapinst scripts with below command line.
#./sapinst SAPINST_USE_HOSTNAME=ascs00
But if we are running on Oracle RAC + GPFS do we need to specify the virtual hostname? If not, which hostname i should use to install the HA for SAP? Please advice.
Regards.

And then I'd continue with the documentation at:
SAP on Oracle => SAP on Oracle Real Application Clusters (RAC)
There you can find several installation guides for windows/UNIX/Linux

2 nodes RAC with Oracle 10g on Windows 2000 server

Hi at all. I want to manage a cluster having 2 nodes on windows 2000 server each of them with Oracle 10g. I have VMWare 5.0. Someone can suggest me a detailed tutorial how to start and built it? Thank you very much for your answers.
Saverio Sergio Mola

the cookbooks here:
http://www.oracle.com/technology/tech/linux/vmware/cookbook/index.html
will explain how to install.. however the VMware Workstation product doesn't offer in a supportedway the sharing of two nodes of disks.. there are hacks out there, but they are not very stable. We therefor chose to install two instances on one node to showcase RAC, rather than make it complicated and unstable to use and showcase.
there are also ready made VM's from above page, so u can quickly evaluate it for both Red HAt and SuSE.. when vmware can support such sharing in an easy supported way we might re-evaluate.. until then my personal suggestion is to stick to simple case.. 2 instances on one node.. its easier to copy, snapshot.. etc.
Enjoy..
