I am getting starting with rac environments. I need to configure a two nodes active/active with rac and I need to know if always using rac both nodes will be active or if I have to do that at some point when installing. I have reading some docs from oracle and others authors about rac and its configuration process but that is not understood for my yet.
View 5 RepliesI have created dataguard between two instances hosted in two different servers. I have done switchover from primary to standby & then again standby to primary with DGMGRL utility.
1- When I done switchover to primary & trying to open standby database in readonly mode it was giving below error-
ORA-01154: database busy. Open, close, mount, and dismount not allowed now
Why this error was coming ?
2- As I was not able to open standby database in read only mode, I have executed below command-
alter database recover managed standby database disconnect from session;
which return an error as-
ORA-01153: an incompatible media recovery is active
After this I have executed-
alter database recover managed standby database cancel;
which executed successfully.
& then after standby database open in read only mode.
Why above error was coming ?
3- After this I had tried to check the checkpoint_change# & controlfile_change# from primary database and result shows both number were different.
Why they are not matching ?
We are using oracle as database in our application. For high availability we have a cluster of multiple nodes and the data is replicated using oracle streams. All the nodes in the cluster are active. We do not have any concept of stand-by.
Now we are planning to use oracle RMAN for backup and recovery. RMAN user's guide doesn't recommend any strategies for such deployments. It mainly focuses on primary/stand-by deployments.

View 2 Replies View RelatedI've got a physical standby database and I'm now licensed for Active DataGuard. I would like to automate the ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION command to be executed right after the STARTUP command so that whenever the database is started by our DBSTART script, it activates READ ONLY W/APPLY immediately after start without manual intervention. This is probably simple, but I figured I'd ask before starting to pore through documentation.....!
View 6 Replies View RelatedDDL statements automatically end with COMMIT the user transactions in which they appear. Foe example:
-------------------------------------------
create table mytable01 (i integer);
insert into mytable01
select 1 from dual;
create table mytable02 (i integer);
-------------------------------------------
After all three statements are executed, data are committed in mytable01.
In the Oracle DB server SQL guide we read:
"DDL commands, such as TRUNCATE, will fail if there is any DML command active on the table. A transaction will block the DDL command until the DML command is terminated with a COMMIT or a ROLLBACK."
But I executed the following without any problem:
-------------------------------------------
create table mytable (i integer);
insert into mytable
select 1 from dual;
commit;
update mytable
set i = 2;
alter table mytable add (j integer);
-------------------------------------------
So where's the truth? Are DDL statements blocked when they refer to an active object accessed from a DML or not?
I'm trying to install 2 nodes oracle RAC 11gR2 on SLES11. I configured DNS for public,virtual, private and scan IPs. when I check with nslookup, everything seems ok. but when I run runcluvfy.sh, it says that:

How can I decrease the response time?
I am cloning my prod db to test with the rman active clone command. I can successfully clone my DB, but after a few hours or so I see messages in the alert log that I have corrupted blocks in several datafiles. Note, i dont see these messages in my PROD DB therefore I think that DB has no corruption. I have few questions:
1) I was reading tha having tables or indexes set with the NOLOGGING option can cause objects to be unrecoverable. Would this affect my active clone?
2) I know you can either change a DB or tablespace to force logging. Is there a query I can use to determine if the DB is in force logging mode.
ALTER TABLESPACE tablespace_name FORCE LOGGING;
ALTER DATABASE FORCE LOGGING;
3) Lastly how to check as why my clone DB would have corrupted blocks.
Here is the clone command I am using.
rman catalog=rman/rman@proddb target=sys/sys@proddb << EOT
connect auxiliary sys/sys@clonedb
duplicate target database to clonedb from active database nofilenamecheck
pfile=/u01/app/oracle/product/11g/dbs/initclonedb.ora ;

I'm trying to set up Active Database Duplication between 2 Oracle 11g servers. Each server is identical, with the following characteristics:
- OS: Windows Server 2008
- Version: Ora11R2 (64 bit)
- DB Name: orcl
- Filesystem: asm (using grid infrastructure)
In addition, each server has been configured with the same sys passwords. The databases themselves were configured during installation (so the setups are about as basic as you can get.)
Now, I've done all sorts of research into how to do this. I've found plenty of good sources, but they seem to all have differences in the details.Here's what I've done so far:
- The TNSNames.ora file on each server has an entry for 'src' and 'dest' (sourca and destination) respectively
- I created an entry named 'SID_LIST_LISTENER' in the listner.ora file on the source machine. However, should the sid_name in this entry refer to the source or destination machine? Or does this listener entry belong on the destination machine instead?
- A lot of the examples require the setup of a new password file and spfile. Are these entries necessary if I'm using the same file structures/user names/etc. on both servers?
I have a RAC on 9i and I want to know the number of active sessions that it's executing the same sql sentence.I'm using this sql but I'm not sure that this query give me te correct result.

I have issue with regards to duplication of an active (prod) database to a test database. This is my sql run by RMAN:
SPOOL MSGLOG to '/proddb/u01/app/dupe.log';
CONNECT target sys/oracle;
CONNECT auxiliary sys/oracle@MWTEST;
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
RUN {
duplicate target database to MWTEST from active database;
}
CONFIGURE DEFAULT DEVICE TYPE TO SBT_TAPE;
It stops however in the middle and wouldn't continue. There is still huge space for the test database (3x the current size of prod database).
I have a active data guard database which is copy of my production database. can i backup the active database using RMAN? The ADG is a read only and dont know, if RMAN can backup an read only database.

View 2 Replies View RelatedI'm trying to set up active database duplication between 2 Oracle 11g servers.
Both servers were set up with identical configurations (same directory structures, file systems, SIDs, and sys passwords.) Both oracle instances were created at the time of software installation.
Here is how things are configured:
- Version: Ora11gR2
- Oracle service name: orcl
- File system: ASM
- OS: Windows Server 2008
I've done some research and found several sources giving instructions on how to set up active database duplication (including a blog engry by rajabaskar on this site), but each site seems to have different details.
So, here's what I have so far:
- Set up entries in each TNSNames file... each has an entry 'src' and 'dst' (for source and destination)
- A new listener has been added on the source machine
- on the destination machine, run the 'oradm' to create a new SID. However, is this really necessary? Since the service names are already the same
- I'm also supposed to create a password file on the destination machine using orapwd. Again, is this necessary, if I'm using the same passwords on both machines?
Am I on the right track? Should I have created an actual database on the destination machine or should I have started with just the software installed?
I'm checking the possibility to use Active Directory to log on the our Oracle databases. But only for dba's and developers, not application users. We use Oracle 10.2.0.4 (and soon 11g) As OS on the databaseserver we use AIX5L 5.3
Is it possible to implement Active Directory on databases running on AIX ? If it is possible, what must be done to get it to work, software ... etc ?

Our product runs a lot of stored procedures in the background to do various things. These stored procedures obviously include a ton of select statements, insert statements, etc. Some of them get pretty complex. Once in a while, we run across the following error: "ORA-03127: no new operations allowed until the active operation ends(3127)." Once this happens, pretty much everything breaks with this error for a while. Eventually (LOOOONG time), this error "resolves itself" and things start working again. Conceptually, I understand that there seems to be some blocking operation on the DB, but because we run a LOT of stored procedures and SQL statements, it's extremely difficult to pin this down.
My workflow stuck in Active status and user is not able to proceed further. But it is not happening every time. Sometimes the process activity gets stuck.
