Oracle 10g SEO replication to Oracle 10g EE RAC

Hi!!!
I have 200 nodes with Oracle 10g Standard Edition One and a DataCenter with 3 nodes Oracle 10g Enterprise Edition Real Application Clusters. My questions is, how to replicate data from each node to datacenter with the objective to centralize all data.
The database structure is the same in all nodes, and there is no conflict.
My real problem is Oracle Standard Edition One, it's not support advanced replication like Streams and Materialized Views, and i cant use other version of oracle because it´s huge money.
Please any advice?
Thanks in advance.

I'm more of an Oracle developer than a DBA, and I'm not sure this is feasible, but it sounds like you are in dire need of an idea, so here it is. Take the transaction logs from your 200 nodes, copy them to your central site (at whatever time interval you require), and peform a "restore" to the central server using those logs, even though they did not come from the central server.

also before you do what is suggested on the url posted by Mufalani,
it seems that you should do the following:
Check existence of udev raw mapping rule file /etc/udev/rules.d/60-raw.rules
On RH/EL5, udev raw mapping rule file /etc/udev/rules.d/60-raw.rules should exist by default as part of the util-linux package, for example:
# ls /etc/udev/rules.d/60-raw.rules
/etc/udev/rules.d/60-raw.rulesCreate a custom udev raw mapping rule file, /etc/udev/rules.d/61-oracleraw.rules say, for example:
# touch /etc/udev/rules.d/61-oracleraw.rules3b. Add udev raw binding rules to /etc/udev/rules.d/61-oracleraw.rules file
Add the udev raw binding rules to the /etc/udev/rules.d/61-oracleraw.rules file, for example:
# cat /etc/udev/rules.d/61-oracleraw.rules
# Raw bind to Oracle Clusterware devices

Note, the script does not factor device name persistency.

Oracle Clustre, Oracle Cluster with RAC and Oracle 10g

Is there a difference between Oracle Cluster and Oracle Cluster with RAC? Please explain. Do existing database codes run unmodified in Cluster or Cluster with RAC environment? What needs to be modified to make existing SQL codes RAC-aware. How to achieve 'all automatic' in case of failure and resubmission of Queries from failed instance to a running instance?
In 10g environment, do we need to consider licensing of RAC as a separate product? What are additional features one derives in 10g that is not in Cluster +RAC?
Your comments and pointers to comparison study and pictorial clarification will be very helpful.

Oracle cluster like failsafe before or Veritas Cluster or other vendor's cluster is meant for HA (high availability) purpose. Which 2 nodes or more can see a shared disk with 1 active node. Whenever this active node failed through heartbeat other machine will know and will take the database over from there.
Oracle RAC is more for HA and load balance. In Oracle RAC 2 or more nodes are accessing the database at the same time so it spread load across all these nodes.
I believe Oracle 10g RAC still need seperate license for it. But you need to call Oracle or check the production document to verify it.
Oracle 10g besides improvement in RAC. It's main improvement is on the build in management of the database itself. It can monitored and selftune itself to much furthur level then before and give DBA much more information to determine the cause of the problem as well. Plus improvement on lots of utility as well like RMAN , data pump etc... I don't want to get into too much detail on this you can check on their 10g new features for more detail view.
Hope this help. :)

How to upgade Oracle from 9.2 on SUN to Oracle 10g R2 RAC on Oracle EL4

Hi all,
I have production database Oracle 9i EE Release 9.2.0.5.0 - 64bit on SunOS 5.9 cca 100GB. I would like to upgrade Oracle 10g Relase2 RAC with 2 nodes on Oracle Enterprise Linux. Database availability is 24x7 and system breakdown must be minimal. Upgrade could be done in several independent steps. What is the best form of upgrade realisation?
Thx for some idea
Libor Veverka
[email protected]

My 2 cents:
1. de-RAC 9i on solaris
2. upgrade to 10g on solaris (why? take advantage of datapump, much faster than exp/imp)
3. expdp from 10g solaris
4. create single instance 10g on linux
5. impdp on linux
Please note there are a number of issues with 9ir2.10gr2 upgrade (check metalink for details).

Plz suggest How configure oracle R12 with RAC using both system .If you want to configure RAC, then you must have the same OS installed on all RAC nodes -- See (RAC: Frequently Asked Questions [ID 220970.1], Does Oracle Clusterware or Oracle Real Application Clusters support heterogeneous platforms?) for details.

Enabling oracle TAF on RAc environment

Hi everybody.
We are using Oracle 10g with RAC and ASM, i'm in testign phase now and i test if the one node is down automatically database connexion will use the other node. Note that we have only 02 nodes. For doing that i ahve seen to a documentation by creating CRM service to enable TAF (Transparent Application Failover). I've created TAF service from Netca and i have the crm service in my tnsnames node1. But when i run the following command:
SQL> show parameter service
i should have
NAME TYPE VALUE
service_names string devdb, CRM
but in my case i have only
NAME TYPE VALUE
service_names string devdb
If any one can tell me why CRM service doesn't appear or how to configure TAF exactly.
I'm running oracle database 10g release 2 on HPUX v11.23 using RAC and ASM and HP ServiceGuard.
Thanks for your help
regards

RAC One Node in 11g still requires the RAC licence option ! (unless you are running Standard Edition !)
All major hardware vendors (IBM, HP, Sun etc) have had clustering solutions.
SunCluster can be configured to allow "failover" of an Oracle Database Instance from one node to another.
The database instance has to be on Shared Storage.
SunCluster, itself, is a separately licensed product available from .......... Oracle now !

10g R2 RAC on Solaris 10 with EMC Storage

We are in the process of setting up 3/4 node RAC with the following components:
Oracle 10g R2 RAC
Oracle Clusterware / Sun Cluster / Veritas Cluster
Sun Solaris 10
EMC storage
ASM/Cluster FS
I would appreciate if some one can through some light on:
* ) Veritas cluster / Sun Cluster is must component or Can I use Oracle clusterware ? what are the advantages and disadvantages of using Oracl clusterware compare with varitas cluster or sun cluster
* ) Is cluster filesystem a compulsory component or Can I use ASM instead of Cluster File system.
* ) If I don't use cluster filesystem where to put CRS repository and voting disk ?
* ) What is best option for Oracle_Home, is it shared oracle home or sepereate oracle_home on each node ?
* ) Are there any known risks invovled in using ASM. How is the I/O performance with ASM on EMC with Solaris ? Are there any best practices
* ) Is GigE okay for interconnect or do I need to go for Infiniband ?
* ) Is there any notes on Best practices for the above components
*) Do I need to consider fail over option for NIC's (interconnect and public), if yes, how to do that ?
*) Are there any other risks do I need to consider ?
Thanks

Hi,
I see lot of good input. I have done few RAC installs on sun/solaris/emc ...
Here are few things to consider.
* ) Veritas cluster / Sun Cluster is must component or Can I use Oracle clusterware ? what are the advantages and disadvantages of using Oracl clusterware compare with varitas cluster or sun cluster
Just stay with Oracle Clusterware. If there are any issues then you only have to deal with one vendor and there will be no finger pointing. In any case Oracle Clusterware is needed even if you install Veritas/Sun.
* ) Is cluster filesystem a compulsory component or Can I use ASM instead of Cluster File system.
For the database you can use ASM. The only time I have considered a cluster filesystem is if external tables were in use.
When you use ASM you need to partition the disk with 1 meg offset or start at cyclinder 1.
* ) If I don't use cluster filesystem where to put CRS repository and voting disk ?
OCR and Voting Disk go on raw devices.
* ) What is best option for Oracle_Home, is it shared oracle home or sepereate oracle_home on each node ?
Install ORACLE_HOME, ASM_HOME and CRS_HOME locally on each server.
* ) Are there any known risks invovled in using ASM. How is the I/O performance with ASM on EMC with Solaris ? Are there any best practices
http://www.oracle.com/technology/products/database/asm/pdf/asm-on-emc-5_3.pdf
We have always installed 2 HBAs and used powerpath.
* ) Is GigE okay for interconnect or do I need to go for Infiniband ?
For a majority of cases gigE is sufficient.
* ) Is there any notes on Best practices for the above components
Have redundancy at each level.
*) Do I need to consider fail over option for NIC's (interconnect and public), if yes, how to do that ?
You can use IPMP. Use large send/receive buffers. Enable Jumbo Frames.
We had to apply some patches.

ASM Installation on Oracle 11g Clusterware (RAC) environment

Hi All,
I am trying to setup Oracle 11g Standared Edition RAC+ASM on RedHat Linux 5.0 VM ware box. As part of this RAC setup successfully completed. For this i have used raw devices and mounted using NFS.
In many of forumns i have read that ASM installtion on a cluster envioronmnet is different than non cluster environment.
I dont know how to start ASM installtion on RAC environment. Please share any documents if you have?
Thanks,
Rakesh

will the steps need to be done on two nodes of cluster or it is sufficient on first node.
"raw device" for OCR, VOTE, SPFILE_FOR ASM and ASM DISKGROUPs
before do "raw devices" you have to fdisk(make partitions) on share storages
node1:
# fdisk /dev/sdf
# ls /dev/sdf*
node2:
# ls /dev/sdf*
don't find...,so just fdisk -> l and -> w
fdisk how? http://linux.about.com/od/commands/l/blcmdl8_fdisk.htm
Example: /etc/sysconfig/rawdevices do it every nodes
#Oracle OCR File +~280M+
/dev/raw/raw1 /dev/sdf1
#Oracle Voting File +~280M+
/dev/raw/raw2 /dev/sdf2
#Oracle ASM spfile ~50M+
/dev/raw/raw3 /dev/sdf3
#Oracle ASM DISK Group1
/dev/raw/raw4 /dev/sdg1
#Oracle ASM DISK Group2
/dev/raw/raw5 /dev/sdh1
And oracle user.. can read /dev/raw/raw* You should find on every nodes
http://oraclepitstop.wordpress.com/2008/02/15/raw-devices-on-rhel-5-or-oel-5/
ls -la /dev/raw/raw*
crw-rw---- 1 root oinstall 162, 1 Jan 13 12:53 /dev/raw/raw1
crw-rw---- 1 oracle oinstall 162, 2 Jan 13 12:53 /dev/raw/raw2
crw-rw---- 1 oracle oinstall 162, 3 Jan 13 12:53 /dev/raw/raw3
crw-rw---- 1 oracle oinstall 163, 1 Jan 13 12:53 /dev/raw/raw4
crw-rw---- 1 oracle oinstall 164, 1 Jan 13 12:53 /dev/raw/raw5
do it on node1 but you have to pass phrase on every nodes Before
http://www.puddingonline.com/~dave/publications/SSH-with-Keys-HOWTO/document/html/SSH-with-Keys-HOWTO-5.html
example:
node01:
$ ssh node01 hostname
node01
$ ssh node02 hostname
node02
- Install + Setup Clusterware:
OCR = /dev/raw/raw1
VOTE = /dev/raw/raw2
- Install Oracle Database for ASM Home
spfile for ASM = /dev/raw/raw3
- after ASM started... create disk groups from /dev/raw/raw4 and /dev/raw/raw5
- Install Oracle Database for RDBMS Home
- Create Database to use ASM diskgroups

Did you followed the same procedure to set up Oracle 11g RAC+ASM on RHEL 5.0.I'd done(test 11gRAC) it on RHEL 4 + 11g + ASM(on raw device)

Which network is Oracle using for RAC traffic ? where you will get info ? ?

Hi,
I am using two node RAC on Oracle 10g R2 (10.2.0.3.0) version on SUN Solaris 10 . I want to know "Which network is Oracle using for RAC traffic ? where you will get info "
--Kumar

Hi Kumar,
In 10g, you can query x$ksxpia. If the cluster_interconnect information is stored in OCR (default), you will get
SQL> select INST_ID,PUB_KSXPIA,PICKED_KSXPIA, NAME_KSXPIA,IP_KSXPIA from x$ksxpia;
If you specified the cluster_interconnects parameter in your init.ora:
Columns to look in : INST_ID P PICK NAME_KSXPIA IP_KSXPIA
And also you can use 'oradebug ipc' to see which interconnects the database is using:
SQL> oradebug setmypid
SQL> oradebug ipc
Hope it helps...
Thanks

I am using websphere 5.1.1.0 server as my application server .Can some one please enlighten me on how can I configure my data source for 10g on RAC ( not stand alone ) . Rather I would like how different is it from configuring data source for a standalone database .

Hi,
Maybe this example cut will work for you. It passes and gets
string:
Statement stmt = conn.createStatement ();
CallableStatement cs = conn.prepareCall ("begin ? :=
MyFunction(?); end;");
cs.registerOutParameter(1,Types.CHAR);
cs.executeUpdate();
System.out.println (cs.getString(1).trim());
