Snapshot standby database in oracle 11g r2 RAC

Folks,
i am just wondering if the process is same for standalone and RAC snapshot standby database.
We have a DR test
1 / I just converted the standalone DR on 11g to snapshot standby database for users to do some testing and reverted back to physical standby after test was done. i folllowed metalink note ID 443720.1
2/ now there is anotherDR test where we have 2 node prod and 2 node DR on oracle 11g rel2 RAC, so not sure we can follow the same process that i used for 11g standalone database. If somebody have done this on RAC, would you please provide the steps ?
Thanks in advance

I haven't done a Snapshot Standby (RAC or non-RAC). But I see no reason why it shouldn't work with a RAC Standby either.
The command is a Database level command, not an Instance level command.

Hello;
Generally for the connection to work you need to add something like this to the listener.ora file :
(SID_DESC =
    (global_dbname = STANDBY.hostname)
    (ORACLE_HOME = /u01/app/oracle/product/11.2.0.2)
    (sid_name = STANDBY)
)You should stop and start the listener on the Standby after adding this. Also your tnsnames.ora must be correct on both the primary and the Standby.
Also you need an INIT for the Standby side :
STANDBY.__db_cache_size=343932928

Keys to success
1. New Standby start NOMOUNT on new password file. ( On Oracle 11 you must copy and rename the file from Primary server )
2. Hard coded listener on new Standby server.
3. Correct tnsnames.ora files.
4. Correct duplicate command.

Procedure for creating logical standyby database for oracle 11g?

Hi all,
can anybody provide me docs /procedure for creating logical standby databse for oracle 11g standard edition.
Aravind

Aravind,
1. The Oracle Standard Edition does not have standby mechanism, you should do it manually or go for Enterprise Edition.
2. It's rather a question for General Database Discussions instead of Peoplesoft.
Any further question regarding that point, please post out there.

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
http://www.oracle-base.com/articles/11g/OracleDB11gR1RACInstallationOnRHEL5UsingVMwareESXAndNFS.php
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)
on production, I use ASMlib... + ASM + 10g

I need to create two databases in oracle 11g on linux.

pls anyone let me know

If you have different databases on same node you could choose to not set ORACLE_SID in shell init file but use instead interactive oraenv Oracle script to set the right ORACLE_SID.

Can i create a standby database in oracle 10g standared edition ?

what are the steps required for creating a standby database using oracle 10g standard edition. or Any other feature for mirroring database in oracle 10g standared edition

Dear mithun,
Please read the following online documentation;
http://download-west.oracle.com/docs/cd/B19306_01/server.102/b14239/standby.htm
+"+
+2.3.2 Oracle Software Requirements+
+The following list describes Oracle software requirements for using Data Guard:+
+* Oracle Data Guard is available only as a feature of Oracle Database Enterprise Edition. It is not available with Oracle Database Standard Edition. This means the same release of Oracle Database Enterprise Edition must be installed on the primary database and all standby databases in a Data Guard configuration.+
+Note:+
+It is possible to simulate a standby database environment with databases running Oracle Database Standard Edition. You can do this by manually transferring archived redo log files using an operating system copy utility or using custom scripts that periodically send archived redo log files from one database to the other. The consequence is that this configuration does not provide the ease-of-use, manageability, performance, and disaster-recovery capabilities available with Data Guard.+

Hope That Helps.

Create an Object in Logical standby database in Oracle 10G

Hi,
I have logical standby database in oracle 10g R2 for reporting purpose.Now i want to create procedure in logical standby which is use to create new temp table in logical standby and contained data generated from select operation on existing table.
Can i create a new user in logical standby database,add new tablespace in logical standby which can insert,update and delete data in standby database base table?
kindly provide me the steps to implement all this.What will be effect if i set guard_Status in v$database is NONE in logical standby?
Thanks,
Shital Patel

Hi Shital,
Guard_status protects the data from being changed.
ALL- By default it is not possible for a non-privileged user to modify data on a data guard SQL apply database. This is because the database guard is automatically set to ALL.
With this level of security, only SYS user can modify the data.
STANDBY- When you set this level of security, users are able to modify data that is not maintained by the Logical apply engine.
NONE permits any users to access the standby database as long as they have correct privileges. This is the normal security for all data in the database.
You can change the guard status value from ALL to NONE in order to allow non-privileged users to modify data and Yes you can create user and extra tablespace in logical standby database..this is what the one of advantage of using Logical standby database.
SQL> ALTER DATABASE GUARD NONE;
Thanks

Oracle 11g R2 RAC on vmware

Hi All,
I have read many blogs and article about installing Oracle 11g R2 RAC on vmware. For self learning process what should be minimum configuration of hardware.
Minimum physical memory will be 8 GB what is minumum processor required ( 2 Cores / 4 Threads) or ( 4 Cores / 8 Threads)?
Native operating system will be Windows 7 64 bit.
Thx.

You wouldn't be doing much with the processors so it won' t matter hugely having a dual or quad core. As long as there is sufficient RAM(like 8gig) , you should be fine. Try to get SSD if you want more faster performance from the machine in terms of IO.

Primavera 6.2 SQL Database to Oracle 11g migration

Hi,
I used the migration tool to migrate a Primavera 6.2 SQL database to Oracle 11G DB. The migration tool runned successfully and I am able to login to the database using P6.2 client with no problem; however when attemptiong to update the license on the now Oracle database using the privuser account I get the following error "License could not be loaded because of error: List index out of bounds (247). Please make sure that you are using a privileged database login" the error comes up before I can browse to the location of licesne.txt file. Same procedure on a "native" Oracle P6.2 database works perfectly with no problem. Has any one run into this problem before? any help will be appreciated.

Best Reagrds,I have not seen that specifically but it appears that not all of the grants were correctly applied.
I would suggest running the schema validation tool which can be found on the knowledgebase as Solution ID: prim75459 as this will tell you what is missing/invalid.
Once you know that, you can pull the neccesary grants from the create scripts located in the cd1\install\database\scripts folder.

To create standby database using oracle 10g standared edition

my producation database is oracle 10G standard edition .Can i implement a oracle dataguard or standby database using standard edition licenses.if standby database is possiable in standard edition .what are the steps for creating a standby database using oracle 10g standard edition.

General answer is http://download.oracle.com/docs/cd/B19306_01/license.102/b14199/editions.htm#BABJICBB.
For Data Guard you cannot :
- use instance parameters to automatically send archived redo logs
- use instance parameters to resolve archived redo logs gaps
- create a logical standby
- use SQL statements to do switchover / failover
- use Data Guard Broker.
