Standalone Standby Creation for RAC database

Hi,
I am in process of configuring standalone standby for my RAC database. The database version is 11.2.0.3. RAC is using SCAN listeners. I have got MOS for configuring standalone standby for RAC 387339.1. But specific steps I need to perform in case of SCAN listeners.
Any document or link is appreciated.
Regards,

How can I have a collective AWR report for RAC database in 10gR2 and 11gR1?

Plz correct me here
awrrpt.sql takes the snapshot at the instance level and incase we have 5 instances we have to take 5 awr reports for a particular period.correct???
If above is true ,any wayout to collect a single collective AWR report for RAC database which includes information on all the instances in Oracle 10g R2 or 11gR1 ?
Thanks in advance
Gagan

I have never come across a way for this. though I can n't say it is not there.
But I guess it may not be feasible too becuase as we know the current AWR report contains data which is specific for one instance.
Various hit ratios, top events, instance effeciency reports.... what not ..
It would be really nice to see something is a new format where it lists values from each instance in a single report.. I guess such a thing Does not exiist as of now.

NETCA listener configuration error for RAC database

Hi,
WE have a RAC setup on 2 nodes and now we want to change the default listener port for RAC database.
Database ver: 10.2.0.4
We now that srvctl does not work to add listener manually to CRS.
We are now using netca to create new listener on both the RAC nodes but it gives error throwing :
Problem in configuration : Node(S): hostname
Try again...
When we try to start the listener say listener_I it throws following error:
Problem in configuration :node1
Listener start to failed:Listener may already be running
CRS-0215:Could not start resource
This is urgent
any help is appreciated.

In-place upgrade of Enterprise Manager for RAC databases is not supported

upgrading 2 node RAC from 10.2.0.1 to 10.2.0.3 on Windows 2003 64 bit. I got the following:
In-place upgrade of Enterprise Manager for RAC databases is not supported in this release
Now I cannot log in to the database control as sys with sysdba role . I get "invalid username/password" error
I can login as a dba user
I also get a java error after I log in, some thing about class not found, but then I'm in and I can do everything that I try, although I haven't tried scheduling a backup yet
Can I upgrade EM to 10.2.0.3?
If so, how?

On the patchset readme...
11.3 Upgrade of Oracle Enterprise Manager Not Supported
When you start Oracle Database Upgrade Assistant to upgrade 10.2.0.1 database to 10.2.0.3 patch set, the following error occurs:
Inplace upgrade of Enterprise Manager is not supported for RAC databases is not supported in this release
Workaround:
Ignore warning.
If you drop and recreate the EM repository?
1). emca -deconfig dbcontrol db repos drop
2). emca -config dbcontrol db -repos create
Be careful, doing this put the database on QUIESCE mode.

RMAN Backup script for RAC Database..please suggest

Hi All,
I am currently working on backup policy for RAC Database for my client.The client requirement is to backup while database is shutdown(mount state).I have made below script and could any one please suggest what further things should I need to add with below rman script.
echo "Shutdown Database";date
srvctl stop database -d PROD
srvctl status database -d PROD
echo "Database shutdown on";date
echo "Mount Database ";date
srvctl start instance -d PROD -i "PROD1" -o mount
srvctl status database -d PROD
echo "Start Full Database Backup on";date
$ORACLE_HOME/bin/rman target / nocatalog <<EOF
configure controlfile autobackup on;
configure controlfile autobackup format for device type disk to '/BACKUP/PRODBKP/%F';
run{
allocate channel c1 device type disk connect 'sys/******@node1-vip:1521/PROD';
allocate channel c2 device type disk connect 'sys/*****@node2-vip:1521/PROD';
backup format '/BACKUP/PRODBKP/PROD_df_%t_%s_%p.bak'(database);
backup format '/BACKUP/PRODBKP/archive_%t_%s_%p.bak' archivelog all;
copy current controlfile to '/BACKUP/PRODBKP/PROD.ctl';
delete noprompt obsolete;
release channel c1;
release channel c2;
exit
EOF
echo "RMAN Backup Finished on";date
echo "Shutdown Database";date
srvctl stop database -d PROD
echo "Start Database";date
srvctl start database -d PROD
srvctl status database -d PROD
Please share your experiences.
Regards

Hi,
Some tweaks for your script.
echo "Shutdown Database";date
srvctl stop database -d PROD
srvctl status database -d PROD
echo "Database shutdown on";date
echo "Mount Database ";date
srvctl start instance -d PROD -i "PROD1" -o mount1. If you database does not shutdown properly , does your script stops the execution of next step?
2. configure controlfile autobackup on;
configure controlfile autobackup format for device type disk to '/BACKUP/PRODBKP/%F';(Why you need to configure this every time) ?
It's persistent at db level one time setting (until some other script changes the settings by other dba - else remove that - set the configuration at db level once for all)

After adding a logical standby database through Grid Control for a RAC database, I noticed sometime later the Data Guard configuration disappeared from Grid Control. Not sure why but it is gone. I did notice that something went wrong with the standby creation but i did not get much feedback from Grid Control. The last thing I did was to view the configuration, see output below.

Specify standby database name and Oracle home location
Specify file location staging area on standby node
At the end am presented with a review of the selected options and then the standby database is created
Has any body come across a similar issue?
Thanks,

Any resolution on this?
I just created a Logical Standby database and I'm getting the same warning (WARNING: No credentials available for target ...) when I do a 'Verify Configuration' from the Data Guard page.
Everything else seems to be working fine. Logs are being applied, etc.
I can't figure out what credentials its looking for.

ODI Connection for RAC database

Hi,
I am trying to create master repository in ODI. We have RAC database and I want to give scan ip for making connection in URL field.
I started repcreate.sh script to open "Master Repository Creation Wizard" and in URL text field I tried to connect by giving single instance detail and its connecting fine.
But when I tried to give scan ip its throwing error message:
java.sql.SQLException: Listener refused the connection with the following error:

Please assit if you have solution.
Thanks
Saurabh

Had the same thing before (in a Hurry) so I created it against one of the Rac Nodes, then edited my Topology connections (Data servers , Work Repos connections, User login profiles) to use the RAC connection and it was fine.
It might be something to do with the RCU not liking RAC conns.
Hope this helps,

DBA panel not working correctly for RAC databases

I hope this is the correct forum for this stuff... I learned that there is a DBA panel in SQL Developer - which is a great idea. But then, trying it on a RAC database, the output is quite confusing. For example, the init parameters are desplayed twice, or better: once for every instance. But a display column to identify the instance is missing. I assume that the query goes to gv$parameter but doesn't make use of the INST_ID column. Or am I lacking some configuration trick...?

This probably has nothing to do with your problem but something is screwed up in the way CSCC handles Configurator panels.
Converted a panel made for CS6 using Configurator4. Got it loaded into CC. It was not quite right so I made some minor changes. The changes never showed up in CC. Deleted the original folder under Panels, changed the name of the panel and reinstalled. Whoa! The original deleted panel was the only one that showed up under Extensions not the new one. This in spite of the fact that that folder no longer existied.
I have tried all sorts of maneauvers but the fact is that the original panel is the only one that PS recognizes even though it does not exist on the drive. It is locked into PS and nothing I have done will change it.

Db context file creation for rac to single instance cloning

DOC ID: 559518.1 Section 6: RAC to Single Instance Cloning mentions that the context file creation should be done as in the case of Single Instance cloning
what would be the command syntax?

Thanks Hussein. However, section 6 of doc 559518.1 mentions that part 5.1.3 when cloning from rac to single node should be done as in the case of Single Instance cloning.
the syntax for rac to rac cloning (which is in 5.1.3) is
perl adclonectx.pl \
contextfile=[PATH to OLD Source RAC contextfile.xml] \
template=[NEW ORACLE_HOME]/appsutil/template/adxdbctx.tmp \
pairsfile=[NEW ORACLE_HOME]/appsutil/clone/pairsfile.txt \
initialnode
so what is the syntax for rac to single instance? I reckon I will still use adclonectx.pl, but now what would be the complete sysntax for single instance cloning?

Standby creation with rac

My system is solaris 10, Oracle database v. 10g.
I'm creating a physical standby database on a remote host.
As there is 2 different sequence number for the 2 thread in the RAC,
select max(sequence#) from gv$archived_log;
thread1 = 76
thread2 = 433
what is the sequence number I have to user for the recover operation.
Thanks for your help
Fabrice

Better than the sequence numbers are the SCNs, check first_change# and next_change# (also in v$archived_log).

Some queries on RAC database 11g

We have RAC oracle database 11g and we don't want to overburden the OLTP instance. So we thought of bringing the changed data from the OLTP instance to reporting instance via logical standby or streams and log the changes with the help of using total recall feature in the reporting instance.
Our idea is to retain the historical data using the total recall feature in reporting instance and bring the changed data from the OLTP instance to reporting instance via logical standby or streams
RAC database: OLTP instance ---> mine the changed data via logical standby or streams ---reporting instance (track all the changes made to a transaction using total recall feature in this instance)
My doubts are:-
1) Whether the total recall feature will work with work with logical standby database or streams?
2) How to transport the total recall feature enabled tables from one database to another. Whether the data pump will work with flashback enabled tables?
3) How to capture the changes from one instance to another with oracle streams. I could not find much documentation on how the streams work on RAC database. Any pointer /suggestion on this would be much appreciated.
Regards,
Richard

1)     Easy backup and recovery for a specific instance in case of historical dataWhat data will that be? If this is a 3rd RAC instance, then it will not make backup easier as the data is in the database (on shared storage media) and that needs to be backed up - the database's data does not reside locally on the instance.
2)     Point-in-time recovery is possibleAgain, I do not see how this is a specific advantage that now suddenly occurs with the introduction of a 3rd RAC instance.
3)     If any other node fails, then it won’t affect this instance Correct - a 3rd instance increases the redundancy in the cluster. It also scales it and provides additional processing capacity.

Can a non-RAC database use SCAN ?

I have a 4 node 11gR2 cluster which has all different kinds of versions ( 10g ,11gR1 & 11gR2 ) on both RAC & NON RAC .
I know for sure that I can use SCAN for non 11gR2 databases for RAC databases .
For standalone db's It seems like it is working intermitently but is this supported ? the reason why I ask is there is no documentation on how to configure or troubleshoot for non-RAC using SCAN .
Appreciate your help
Ravi

I was trying to find some information about the issue, but i think SCAN is really designed for RAC databases.
You don't really need to use the SCAN for what you just described:
you can update the client tnanames with the vip addresses of all nodes with FAILOVER = ON
Example:
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=TCP)(HOST=node1-vip)(PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=node2-vip)(PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=node3-vip)(PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=node4-vip)(PORT=1521))
(FAILOVER = ON)
(CONNECT_DATA=(SERVER = DEDICATED)(SERVICE_NAME=DB.WORLD))
However, you can try this (i never tried it, but i think it should work):
- See the document http://download.oracle.com/docs/cd/E11882_01/install.112/e10813/undrstnd.htm#BEICFAIC
+... If you do not set LOCAL_LISTENER, then the Database Agent automatically keeps the database associated with the Grid home's node listener updated...+
So don't set the LOCAL_LISTENER in your db.
- Update the client tnsnames with the SCAN if the version of the database is 11.2.0.1
- Try to see if it works fine
- Move your db to another node and try again
