Hot Backups - Oracle 9i, 10g and 11g
Are all hot backups run outside of RMAN as an OS file copy? If so, isn't this a very risky exercise.
I understand that RMAN will check for corruption where as hot backups won't. RMAN can also track backups in a recovery catalog.
If using a hot backup, it seems like corrupt data could be backed up with the good data.
What exactly are the advantages of using a hot backup. It is understood that the databases can be up during a hot backup, but can't they also be up with an incremental RMAN backup?
I think you need to read the documentation again. Check on tahiti.oracle.com
A cold backup is when the database is shutdown (can be done by file copy or rman)
A hot backup is when the database is running (can be done by file copy or rman)
RMAN has the advantages of backing up at block level, and going directly to tape, and compression, and incremental backup, and block checking, and backup from ASM, and catalog ......
File copy has the advantage of being logically simple (e.g you can see exactly what is happening when you copy a file).

Difference in select for update of - in Oracle Database 10g and 11g
Hi, I found out that Oracle Database 10g and 11g treat the following PL/SQL block differently (I am using scott schema for convenience):
DECLARE
v_ename bonus.ename%TYPE;
BEGIN
SELECT b.ename
INTO v_ename
FROM bonus b
JOIN emp e ON b.ename = e.ename
JOIN dept d ON d.deptno = e.deptno
WHERE b.ename = 'Scott'
FOR UPDATE OF b.ename;
END;
/While in 10g (10.2) this code ends successfully (well NO_DATA_FOUND exception is raised but that is expected), in 11g (11.2) it raises exception "column ambiguously defined". And that is definitely not expected. It seems like it does not take into account table alias because I found out that when I change the column in FOR UPDATE OF e.empno (also does not work) to e.mgr (which is unique) it starts working. So is this some error in 11g? Any thoughts?

It seems that my question was answered here - http://stackoverflow.com/questions/2736426/difference-in-select-for-update-of-in-oracle-database-10g-and-11gThe behaviour seems like it really is a bug and can be avoided using non-ANSI syntax. (It makes me wonder why Oracle maintains two query languages while dumb me thinks that this is just a preprocessor matter and query engine could be the same).

Running Oracle database 10g and 11g on same 5 RAC nodes
Hello Gurus,
Could any body throw light if I can install and sucessfully run Oracle database 10g and 11g on the same Oracle RAC installation setup.My setup is below
Number of nodes-5
OS- windows 2003 or RHEL5
storage- DELL EMC SAN
Clusterware- oracle version11g
File system-Automatic storage management(ASM)
After I successfully setup clusterware,ASM on the nodes,I would want to install 11g database on all 5 nodes .
Then Install 10g database on only 3 of the nodes using the same clusterware.
What are your views on the same.
Also FYI... as per metalink node 220970.1(RAC: Frequently Asked Questions) one can do such a setup.
what iam looking for is practical experience if anyone has implemented this in production system,if yes any issues faced and how tough it is to support.
Thanks,
ImtiyazYou could run an 11g database and 10g database on the same cluster as long as you use Clusterware 11g.
The administration aspect will drastically change according to the platform you run on. As of now, it appears you don't know whether it will be Linux or Windows.
It would be practical to support the same database release. -
Difference between oracle bpm 10g and 11g
Newbie: I am trying to understand 10g. The basic questions I have is
1)What is the difference between 10g and 11g?
2)What is the infrastructure & skillset needed for me to do implementation in 10g?
3)How is migration from 10g to 11g is accomplished?
Any resource links that would help me to get started with 10g would be appreciated.

Doubt with Windows and Oracle Forms 10G and 11g
Hi
I have some doubts in installing Oracle Client on Windows.
a)Can we install Oracle Forms 10g and Reports 10g client on Windows 7?
b)Can we install Oracle Forms 11g and Reports 11g client on Windows XP?
c)If we have an Oracle Forms 11g and Reports 11g, can it connect to a 10g Server?
d)If we have an Oracle Forms 10g and Reports 10g Client, can it connect to an 11g Server?
Please, Can any one help me in this????a)yes it can be installed on win7, may have some issues on 64bit systems but they're solvable
b)11g had some problems with windows 2000, but didn't see mention of any problems on XP
c)if you mean a database server then yes - i managed to connect 11g to an 8i database, so v10 should not be a problem. If you mean a forms/reports server..well newer forms/reports builder might not want to run old forms/reports and vice versa, but I don't see the point of operating on the same files from different versions. You can still load old form/report source files with a newer builder and recompile them to run on the new server.
d) the "client" is effectively your web browser with a java plugin, unless I misunderstood your question. What version was a form/report compiled with should not be an issue. -
Differences between Oracle Discoverer 10g and 11g (EBS & Desktop)
We are in the process of upgrading from Oracle Discoverer 10g testing to Oracle Discoverer 11g.
We have had several requests (from functional users) for documentation that might reflect the changes in this release level. Does anyone have relevant documentation that might help explain what has changed so that they can be better prepared.We are in the process of going from 10 desktop to 11 plus. I do not like it as other end-users I have talked to don't either. In desktop, I could have multiple reports open at one time, move tabs from one report to another so I wouldn't have to rebuild the report again. Also, there are times I have 3 or more sessions of desktop running with multiple reports running in them. In plus, I am limited to one session and one report. That slows down productivity big time. In desktop, exporting crosstabs to excel is more user friendly than plus. For desktop, it will fill in the cells below with the data above it if it changes. In plus, it looks like a pivot table. I have read other posts on how to work around that, but not always functional. Using Dense_Rank() works sometimes depending on how the report is written. IT is researching another way but haven't heard back from the consultants. Or, I will have to modify all my excel files with formulas to do that for me. Also in desktop, I can select all and copy paste the results into excel and all data comes in. The row and column headers, page items and even the title section will paste into excel. Plus only gives you the data, no row or column headers. So I have to export it every time I need the data. I have formatted excel files that all I need to do is copy paste and data flows beautifully. As for organizing and saving reports, desktop is much better. I can save reports out on our network under different folders so I can find them faster by topic. Granted, if that directory is an open one, anyone can change/delete it. In plus, the only advantage of saving it on the database is I can sort and search for reports or users. If you make any changes in plus and then walk away from your desk, plus will shut down after a certain time period. If you didn't save it, you have to start over. Don't know if this is something IT can fix???
As we see it, plus is a step back in technology. I hope someone can change that opinion. Don't know if we are not getting the best support from whoever is working with us (Oracle or 3rd party) or we are missing something???? If so, please share.
Thanks. -

Hi all,
I would like to know what the differences between Oracle and other NoSQL database are.
When and why should we use Oracle?I suggest that you start here:
http://www.oracle.com/technetwork/database/nosqldb/overview/index.html
Is Oracle NoSQL database link with Big Data Appliance?Yes, Oracle NoSQL Database will be a component of the Big Data Appliance.
Can we use map-reduce on a single personal computer? How should we install Oracle NoSQL database to use map reduce on a single personal computer?Yes, I believe you can run M/R on a single computer. Consult the various pieces of documentation available on the web. You may run Oracle NoSQL Database on the same computer that you are running M/R on, but it is likely that they will compete for CPU and IO resources and therefore performance may suffer.
Do we also have eventual consistency with Oracle NoSQL database? Yes.
Can we lose data if master node fails?If you run Oracle NoSQL Database with the default (recommended) durability settings, then if the master fails, a new one will be elected and data is not lost.
Are transactions ACID with Oracle NoSQL database? How can we prove it?Yes, each operation is executed in an ACID transaction. The API has the concept of "multi" operations which allow the caller to perform multiple operations on sets of records with the same major key, but different minor keys. Those operations are also performed within a transaction.

Important differences between oracle 10g and 11g
Hi friends, can anyone tell me (pointwise) what are the major (and minor) differences between Oracle 10g and 11g.
Please point me to some documents if possible.
Thanks in advanceThe name of the link says it all: "top_features."
In short it is Oracle's list of what they have for marketing and sales reasons designated "top features."
It is not intended to be, and is not, a complete list of features. Often the features Oracle does not
talk about are the most important.
Let me give you some examples. I have never seen Oracle announce DBMS_XPLAN as a new feature
yet you should not run an explain plan without it. Neither have I ever seen Oracle announce the new
NO_DATA_NEEDED predefined exception. I have listed literally hundreds of new features you will not
find in Oracle's new features docs.
I did a presentation at OpenWorld this year as part of the unconference titled "New Features in
Database 11gR2 that Oracle will not announce." It was easy to prepare a one hour presentation with
little fear of being proved incorrect. As I turned out only one of the features I presented was mentioned
by Oracle.
You can find the presentation slides here:

Installing oracle 10g and 11g client on the same Linux RHEL 5.4 host
Is it possible to install Oracle 10g and 11g client on the same Linux RHEL 5.4 host and have the application switch between 10g and 11g? and how would the 10g and 11g be installed?
Thanks for your reply.
Typeically if 10g is installed in /home/roacle/product/10.2.0, are you saying that for 11g, it would be /home/oracle/product/11.0.0 ?
How about switching the application? Does changing the ORACLE_HOME and PATH environment variable setting enough ? Let's say from
