Oracle 9i database to oracle 10g rac

Hi all,
Here is my situation:
I have a client who wants Oracle 10GR2 RAC with OCFS2 on RHEL5 using FCP and Netapp storage.Till here I am ok, now he has nine different existing oracle 9i database single instance running on various RHEL3 servers, each of these database are small databases of 20-50GB max. Now the client wants the following:
1. Move all these individual databases to the new RAC servers, which means I will have nine different database and instances.
2. What is the fastest way to do it, I can get full database shutdown during weekends.
Can I copy these databases to the new rac servers and make a new controlfile, will 10G read the 9i DB from the new locations?
How do I make these db's into a rac instance?
please help, very urgent.

You need to ask this on the database forum, where thereare other threads that deal with 'complex' upgrades

New database creation in 10g RAC

Hi,
I'm trying to create a new database using DBCA in 2 node RAC cluster. When I select custom database and the password for sys and system users. In the next screen I select ASM and it is asking for password. When i give the password which i entered before for sys and system, it is not taking. Even i tried different password but getting an error password for user SYS is not valid. Any idea what the issue is?
Thanks

You must have created an ASM instance prior to creating the database. DBCA won't create an ASM instance alongside with a database.
As the ASM instance apparently doesn't exist, you can't connect to it,
Create an ASM instance first.

Database cloning in 10g

Hi Masters!!!
I have to clone a database, please do you have any reference, that I can read?
Thank you.
Paola
@}--->--->----

There are two ways to clone a database, first the traditional copying of datafiles, logfiles, redologfiles, and the configuration environment. i.e. db and instance name, initialization parameter file, password file, reconfigure file paths with the traditional ALTER DATABASE RENAME FILE command.
The second way uses rman as the simplest way to clone (my personal favorite), Ref. http://www.oracle-base.com/articles/9i/DuplicateDatabaseUsingRMAN9i.php
First we must create a password file for the duplicate instance:
    orapwd file=/u01/app/oracle/product/9.2.0.1.0/dbs/orapwDUP password=password entries=10Next add the appropriate entries into the tnsnames.ora and listener.ora files in the $ORACLE_HOME/network/admin directory. Remember to load the new configuration into the listener:
    # Added to the listener.ora SID_LIST
    (SID_DESC =
      (ORACLE_HOME = /u01/app/oracle/product/9.2.0.1.0)
      (SID_NAME = DUP)
    # Added to the tnsnames.ora
    DUP =
      (DESCRIPTION =
        (ADDRESS_LIST =
          (ADDRESS = (PROTOCOL = TCP)(HOST = server1.tshcomputing.com)(PORT = 1521))
        (CONNECT_DATA =
          (ORACLE_SID = DUP)
    # Reload listener
    lsnrctl reloadNext create an init.ora file for the duplicate database. Since we are duplicating the database onto the same server as the original we must convert the file names so there is no conflict:
    # Minimum Requirement.
    DB_NAME=DUP
    CONTROL_FILES=(/u02/oradata/DUP/control01.ctl,
                   /u02/oradata/DUP/control02.ctl,
                   /u02/oradata/DUP/control03.ctl)
    # Convert file names to allow for different directory structure.
    DB_FILE_NAME_CONVERT=(/u02/oradata/TSH1/,/u02/oradata/DUP/)
    LOG_FILE_NAME_CONVERT=(/u01/oradata/TSH1/,/u01/oradata/DUP/)
    # make sure block_size and compatible parameters
    # match if you are not using the default.
    DB_BLOCK_SIZE=8192
    COMPATIBLE=9.2.0.0.0Next we connect to the duplicate instance:
    ORACLE_SID=DUP; export ORACLE_SID
    sqlplus /nolog
    conn / as sysdbaNext we create an SPFILE based on the init.ora:
    CREATE SPFILE FROM PFILE='/u01/app/oracle/admin/DUP/pfile/init.ora';Next we start the database in NOMOUNT mode:
    STARTUP FORCE NOMOUNT;With the duplicate database started we can now connect to it from RMAN. For the duplication to work we must connect to the original database (TARGET), the recovery catalog (CATALOG) and our duplicate database (AUXILIARY):
    ORACLE_SID=DUP; export ORACLE_SID
    rman TARGET sys/password@tsh1 CATALOG rman/rman@tshadm AUXILIARY /We can then dupicate the database using one of the following commands:
    # Duplicate database to TARGET's current state.
    DUPLICATE TARGET DATABASE TO DUP;
    # Duplicate database to TARGET's state 4 days ago.
    DUPLICATE TARGET DATABASE TO DUP UNTIL TIME 'SYSDATE-4';;)

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?

Using ASSM in 10g RAC with SAP

Hi,
It is recommended to use ASSM (Automatic Segment Space Management) with using 10g RAC with SAP. Our deployment is currently a single instance database that is not using ASSM. We plan to convert this single instance database to a 10g RAC database. I wanted to know what the supported method is to convert to ASSM, during this process.
Will it require an export and import of the database?
Thanks

Hi Badar,
of course you can move tables (w/o longs) via ALTER TABLE MOVE... but why do you may want to do that?
ALTER TABLE MOVE is an OFFLINE action - nobody can access the table during the move.
DBMS_REDEFINITION (used by the BRTOOLS) is ONLINE. Normal work can proceed while the data is copied.
With ALTER TABLE MOVE you've to touch every single table (ca 50.000-80.000 in a SAP installation) by hand. PLUS you've to rebuild each index on each table by hand.
The BRTOOLS do all that for you. In parallel if you want to.
Moreover the BRTOOLS provide extensive logging in case any error should occur. ALTER TABLE MOVE does not.
So better forget about ALTER TABLE MOVE... use the BRTOOLS - they are not that bad
best regards,
Lars

11i eBiz RAC 9i database cloning to a envronment with existing 10g CRS

production is 9.2.0.8 RAC Need to clone production to lower instance using Rapid Clone. Has done such clone before.
The new issue is there is an another 10g RAC database with 10g Clusterware has been installed in this server and the cloned 9i RAC need to co-exist with this 10g RAC database.
I am thinking to use 10g clusterware to manager 9i RAC database.
From cloning point of view, how to clone a 9i RAC database to an environment with 10g clusterare.
Should I use 9i oracle home 9.2.0/appsutil/clone/bin/adcfgclone.pl or should I use 10g oracle home adcfgclone.pl?

Hi,
production is 9.2.0.8 RAC Need to clone production to lower instance using Rapid Clone. Has done such clone before.I did not try this type of clone before. However, I believe you cannot use 10g ORACLE_HOME as cloning 11i instance with Rapid Clone on 10g database requires additional manual steps which cannot be applied to the 9i ORACLE_HOME. From Rapid Clone point of view, I believe you need to issue adcfgclone.pl from the 9i ORACLE_HOME

Oracle database not starting up in oracle 10g RAC

Hi!
Recently I came across one problem with one node oracle 10g RAC.When the Oracle database is started,while opening it is giving ORA-03113:End of file on communication channel error.When I saw the the alert trace file and other trace files I found Disk group is exhausted error and it is not able to create .dbf files.Actually it is not a production server and I gave archive log destination in SAN.Even the spfile(content of init_database.ora) is in SAN..
I tried Asmcmd utility to delete the archive log files.As the oracle is not available I am not able to asmcmd prompt.
How to change the destination of archive log and to remove the old archive log files(as it is a testing environment we can remove) from SAN?Please let me know.
Thanks & Regards

On VMware there's a known issue with Oracle databases on a Windows client not starting up properly all the time and a manual startup using oradim -start -sid <whatever> is required to get it fully running. Hmmm, doing it several time, and never seen such issue. Which "known issue" and by who are you talking about ?
I created a brand new Oracle VM Windows 2003 32-bit server, installed the Oracle drivers for paravirtualization, and whammo, the problem is still hereI'm sure, you miss something somewhere in the config. Right now, you're on supported configuration, you could either raise a SR to the support, or get help from your peer on Oracle Database General forum.
Ah, but it's not a Windows issue. On a non-VM Windows box the database starts just fine all the time. Again, this is a known issue acknowledged by Oracle on the VMware side, I'm just surprised it exists on the Oracle VM side.Again, give more details about this "known issue". Never heard about that, eventhough I've been around for years.
I was afraid you were going to ask that. I'll have to search for it again, but I think you can do the same as well....Well, I doubt you could find a Metalink note about Oracle on VMWare. So far, Oracle has always refused to support database on OS virtualized on VMWare (or any VM software other than Oracle VM). Based on that, you could be sure, your "known issue" is not an issue on Oracle VM.
If you want more help, again, give more details about your issue.

NIC ROUTER requirement for 10g RAC database

I need to know what hardware to order in setting up an 10g RAC database without a single-point-of-failure. My question centers on the networks. If each server has one NIC for the public interface and one NIC for the private interconnect, aren't the routers these NICs are attached to a single point of failure? If each server has two NICs bonded together for the public interface and two NICs bonded together for the private interconnect, does each NIC attach to a different router?

is RDMA and infiband ar same??Infiniband is a switched fabric layer for high speed communication. RDMA is a protocol for "+remote direct memory access+".
Infiniband supports the Internet Protocol suite over Infiniband, or IPoIB. It also supports RDMA over Infiniband.
so do we need only infiband SDR / QDR switch to set infiband OR what else??You need an Infiniband switch - Cisco and Voltaire are two companies that supply this type of hardware. The latter is used by Oracle in its Exadata database machines. Unsure about Cisco's commitment to Infiniband switches as they have discontinued their Infiniband switches with integrated fibre channel gateways. A sore point with us after we bought into this technology about 2 years ago, in part on their very own recommendations - and now own very expensive, somewhat buggy and totally unsupported hardware. Seems like the new Cisco California servers are GigE and not Infiniband, which perhaps explain this (flawed) decision of theirs...
For each cluster node, you need an Infiniband PCI card (typically has 2 ports). If you are going to use bonding, you will need a pair of Infiniband cables per server. Also remember to get spares - both PCI cards and cables.
If you want redundancy at the switch, you need to get yourself 2 Infiniband switches.
But if you're planning to invest this into a RAC cluster, then surely you should also invest money in RAC licensing and support - and with that gain access to very useful documentation like the RAC Starter Kit and so on.

Oracle Database 10g - RAC install

1)
I am trying to install Oracle 10g RAC (for Solaris Operating System (SPARC)) using 'Enterprise/Standard Edition for Solaris Operating System (SPARC, 64-bit) - ship_rel10_sol64_db.cpio.gz' downloaded installation. There is no separate installation for RAC, so I assume this is the right install to use for RAC, right?
Since I don't have cabeling for Interconnect done yet, I tried to install Database/RAC prior CRS installation, but no option has been offered for RAC. Do I need to have clustering software installed first in order to be able to installl Oracle Database RAC?
2)
Why is Oracle Database 10g release 10.1.0.3 patch set (for Solaris Operating System (SPARC)) so large - 648 MB?
Do I need to install 10.1.0.2 first?

Hello,
there's no extra RAC software package, but the option is only offered, if one of the supported cluster layers for the respective OS has been installed before.
10.1.0.3 looks like a complete redesign, but anyway it is a patch, you have to install 10.1.0.2 first.

How to start Oracle 10g RAC database and clusterware?

I have steps to stop the 10g RAC Database and clusterware but not sure about starting it.
I have heard executing
$crsctl stop crs --as root
on each node
will start the database,asm,nodeapps .Is that true?
or we have to do that step by step like we do in stopping the clusterware and database below
1.Stop the agent:
cd to $AGENT_HOME/corpng04.amhc.amhealthways.net/bin, then run: ./emctl stop agent
2.Stop the full database
$ oracle_home/bin/srvctl stop database -d db_name
3.Stop the ASM Instances on node1,node2
$ oracle_home/bin/srvctl stop asm -n node -- I guess you can't give multiple nodes in one command with comma,you need to give this multiple times with diff node name
4.Stop the NodeApps :vip,listener,oms and gsd
$ oracle_home/bin/srvctl stop nodeapps -n node -- I guess you can't give multiple nodes in one command with comma,you need to give this multiple times with diff node name
5.Stop the CRS cluster processes :those bloody 3 evmd,ocssd,crsd
$su - root
$CRS_home/bin/crsctl stop crs

Paul R @ NL wrote:
before is shutting down crs i tend to stop the instances and services via srvctl then stop crs via crsctl
just the way i do it. not saying it's the right way but it is the one i am comfortable with.Good -) If we stop CRS, but forgot shutdown oracle instances ... we'll see shutdown abort in alert log file(that mean instances are shutdowned abort).
We should shutdown instance before stop CRS anyway.

Cloning Oracle APPS Rac Database to Non Rac Databse

Hi all,
I have question.
Presently we are following RMAN duplicate database cloning from RAC asm to (non RAC)non asm database of size 1TB.
If suppose if our databse is 3TB or More. then is there method that we can minimize the cloning time. If so please let me know.
Thanks

Oracle database 10g RAC and ASm installation

Hi all,
I want to ask to everybody something about Oracle 10g RAC and ASm configuration. We plan to migrate to Oracle 10g from 9i, and we will begin configuring oracle but we have to decide which configuration are the best.
Our materials are bellow:
Hardware: RP 3440 (HP)
OS : HPUX 11i Ver 1
Storage: EVA 4000 (eva disk group)
The problem is:
Our supplier recommand us to use HP serviguard + HP serviceguard extension for RAC+ RAc and Raw device as configuration.
But we want to use Oracekl Clusterware + RAC + ASM
My question is if anybody know what is the best configuration, we want to use ASm.
Can we use HP serviguard and ASM.
Some documentations or link explain oracle RAC and ASM configuration will be appreciate.
Thanks for your help.
Regards.
