Oracle 12c disable EM Database Express

It seems less obvious now that db console (database express) is stored within the database how to disable it. We already have EM 12c Cloud, is there any benefit to have database express also run standalone? If not, is there a recommended way to disable it altogether?

You can disable all access to DB Express by stopping the listener service. For example,
exec dbms_xdb_config.sethttpport(0)

What features says Oracle 12c, a cloud database?

Hi all,
I'm new cloud computing world and would like to what features bring 12c as a cloud ready database? Is it multitenant and/or are there any more things considering?
thanks
Pradeepa

There are many more features that were put in the 12c release specifically to make it a first class citizen for cloud deployments. Please take a look at the following links:
- Oracle White Paper:
http://www.oracle.com/technetwork/database/plug-into-cloud-wp-12c-1896100.pdf
- independent 4-page review:

Hope this is helpful.

Oracle 12c in- memory database option

I did not go to oow 2013, but watched Larry Ellison's video on Orcle 12c in memory option. Seems amazing tecnology, hard to beleive everything can be done behind the scene once one sets some parameters in init.ora. I alreday have 12.1 intsalled on OEL 6.4 on my VMWare, wbat to play with it but do not see any download links on technet.oracle.com.

It's just announced so wait for some time and I believe, it's not going to take "just few parameters" only.

Oracle 12c em express

I am used to working with database control in Oracle 10g and Oracle 11g.
Now I have an Oracle 12c and created em express as part of db creation.
I foind that EM express does not have all the functionality of DB Control; i.e.. I cannot see awr reports, etc.
Do I need to install Oracle 12c clound control to see all the functionality which was available in DB Control.

You can review OEM 12c new features below,
http://docs.oracle.com/cd/E24628_01/doc.121/e25353/whats_new.htm
Regarding the example AWR report you can see below links,

What are MD_ tables in Oracle 12c database? What is their purpose?

I just set up an Oracle 12c database with the purpose of migrating an existing Oracle 11.2.0.2 database. Our application developers are a bit confused when it comes to the schemas suddenly having MD_ tables they did not create. Any help is appreciated.

Did you do this using sql developer and the migration workbench to create a repository?
See if anything in this article rings a bell:
http://oraexplorer.com/2008/06/oracle-sql-developer-migration-workbench/#sthash.gNFtpafS.dpbs
Next, you will need to create a repository. An database account, which has CREATE SESSION, RESOURCE, and CREATE VIEW must be created first. Then logon into SQL Developer as that account. From the tool, create a repository from Migration menu > Repository Management > Create Repository. This process creates a bunch of MD* and MIGR* tables and packages.
I ask because you said you 'set up an Oracle 12c database' but then implied your developers are accessing it.
Most people experimenting with 12c create a multitenant database which has a CDB and one PDB that contains the sample schemas.
You typically would NOT allow developers access to the CDB; that is for admin purposes only. So, hopefully, if you developers access anything it is ONLY the sample PDB or a PDB that you have created from the seed.
Make sure you, and your developers RTFM about the new multitenant architecture or you will all get horribly confused when you try to do simple things like create users or issue grants. All of that works VERY differently in 12c.
See chapters 17 and 18 of the Database Concepts doc
http://docs.oracle.com/cd/E16655_01/server.121/e17633/cdbovrvw.htm
Pay particular attention to the discussion of 'common' and 'local' users. And a hidden 'gotcha' is that the PDBs will NOT be started/opened by default when you do a 'startup' of the database. If you create common users those users will NOT be created in PDBs that are not open; so there is the potential to have to do perform a lot of manual maintenance if you need to add those users to PDBs that weren't open at the time you added the users.

Can somebody that knows this, or has installed Oracle Express on Ubuntu, to please explain it to me what does it mean and why am I getting those errors. Please explain thoroughly as if I am an amateur person, IN DETAIL, STEP-BY-STEP. I want to run it and make it work! I heard that it encourages people to answer for points. I am open for your suggestions and experiences, as long as it's not 'use common sense', 'you're dumb', or an answer that is vaguely explained. Thank you for those that take the time to read it.

Using Oracle Database Express Edition in development environment

Hi All,
I have doubt regarding the usage Oracle Database Express Edition in Development environment. I am not sure weather I can ask a non technical question here or not. Pleas forgive me if I have done any thing wrong.
I am working in an IT company where we take up projects outsourced by our clients. As part of our current project we are making some modification to a web application used by an institution. Our client is using Oracle Data Base standard edition. Due to budgetary constraints of our Company we can not set up a Oracle standard edition data base in our development environment.
So would it be illegal if we use Oracle Database Express Edition in our development environment? We can guarantee that only our internal development team which comprise a maximum of 10 people will have access to this development database and this development data base will never be opened to our Client for their business purpose(Who have their own Oracle standard edition in their environment). As part of the project we delver only table DDL script and stored procedure to our client and they put it in their environment.The sole purpose of a internal Express database will be development only.
Could some one please tell me if it would be violation of license agreement if we install Oracle Database Express Edition in our development environment.

Hi Paul,
Actually I have already gone through the Oracle Technology Network Developer License Terms for Oracle Database 11g Express Edition . But was not quiet clear about the content. It says in the license terms that "We grant you a nonexclusive, nontransferable limited license to use the programs for: (a) purposes of developing, prototyping and running your applications for your own internal data processing operations". Does the term "your application" includes an application we are developing for another company. Since the Express database is installed in the development environment only and is not opened to any one else not even for Our client it definitely falls under the term "internal data processing operations" right?

Does the oracle golden gate version 11.1.1.1.2 support oracle 12C database ?

Hi experts,
Currently in our environment we are having Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit DB which is replicated via oracle golden gate version 11.1.1.1.2. As per the application team requirement we need to migrate this database to 12C.
Can any one help me on the below queries
Does the oracle golden gate version 11.1.1.1.2 support oracle 12c database ?
Are there any syntax changes in oracle goldengate versions which needs to be taken care in extract or replicat parameter files ?
Thanks,
Mushraff Shaik

Hi,
>>Does the oracle golden gate version 11.1.1.1.2 support oracle 12c database ?
Why do you think it will not support 12c database ?
From a Golden Gate perspective you need to create schema and use that. As you are moving to 12c database, ideally you should think of upgrading Golden Gate 11.1 to 12c so you can use new feature such as Multi Threaded replicate etc..
HTH,
Pradeep

Downloading Oracle Database Express Edition

Hi everyone. I just downloaded the freeware Oracle Database Express Edition without any apparent problems. However, when I attempt to go to the Express Edition Homepage, which is location http://127.0.0.1:8080/apex,

I cannot understand why this is the case since I successfully added Web site 127.0.0.1 in my Control Panel (as specified in the instructions.) Also, the instructions stated that HTTP port 8080 was the default port, unless my system said that this was not available (which it did not.) I also tried rebooting, which did not make a difference.

Upgrade oracle database express edition

good morning

best regards

I've a question i'm working with oracle database express edition but now the memory is full and i want to upgrade it to oracle enterprise edition Hi,
Not to dissuade you from that, but that's quite a leap from XE to EE, are you sure that SE One or SE would not be a 'better option' for you?
Also, by 'memory is full', I assume you mean you've reached the 4Gb data limit?

Oracle Database Express Edition 2 Day Plus Java Developer Guide??

I posted in the JDeveloper forum, as well as sending email via your feedback link found on the tutorial but I am a little disappointed by this:
The Oracle® Database Express Edition 2 Day Plus Java Developer Guide has some errors in it.
in Windows, I simply chose, start
-> programs -> Oracle Database Express Edition -> Go To Database Home Page -> click documentation from the link -> and run the Oracle® Database Express Edition 2 Day Plus Java Developer Guide tutorial.
the problem is there are mistake(s) in the tutorial, for example: section 4-19 is this:
"The complete code for the method should now be as follows:
public boolean authenticateUser(String userid, String password,
HttpSession session) throws SQLException { "
it needs to be this:
public boolean authenticateUser(String jdbcURL, String userid, String password,
HttpSession session) throws SQLException {
Also:
there is no mention that :
the port and SID must also be passed in the
ds.setURL(jdbcUrl) found in the authenticateUser() method, or an exception is thrown. This differs from value of the jdbcUrl string found in the getDBConnection() , which makes it hard to figure out
The tutorial is great even if it doesn't work out of the box, but I am disappointed that errata or completed code for this project is not available, especially when you explicitely point to it via the steps mentioned above.
Thanks,
Patrick

The tutorial seems to be using the old JDeveloper 10.1.2.
If you are aiming to learn JDeveloper then just use the tutorials linked from the JDeveloper home page.

Oracle Database Express Edition SQL Developer

Hi all,
I did download the Oracle Database Express Edition from Oracle's website and am trying to create a new connection with the following info
Connection Name: myconnection
Username: ora21
Password: ora21
Hostname: localhost
Port: 1521
SID: orcl
Note: I even tried to use xe as the SID since it's a express edition but it keeps telling me test failed: ORA-01017: invalid/password; logon denied.
Could it be because it's an Express edition? Please advice as am a new DBA and am practising on my own

@Jim: thanks for the reply! I just created the user ora21 but when I try to creat the connection again it gives error ORA 01045 : user ORA21 lacks create session privilege; logon denied.

Help!There is a forum dedicated to Express Edition, in which we have discussed a lot of the variants in failure that causes this problem. At the top of the page you are reading, there should be links like "Forum Home » Database » Database - General". The middle one will get you to a list of all Oracle forums and after the first 5, the rest are alphabetical - XE is pretty far down that page.
(You might also note that there is an Installation forum next to this one. That might be better suited to the task than the 'catch-all' general forum.)
The most common issues are related to not preparing the operating system properly. For example, if you use a laptop you probably use DHCP to get a different address from the various sites you connect to. However, Oracle works as a server and depends on having a well known address. In fact, it tends to bind the IP address at install into it's configuration files. Therefore it is critical to use the loopback adapter in such situations.
Other issues are dependent on the actual OS into which you install. For example, Ubuntu (Linux) has very differnet install philosophy as Red Hat / Fedora, and requires a different install technique. Then again, on Windows, it is nearly impossible to install anything Oracle on a Windows 'Home' OS, and XE generally has not even been tested against Windows 7.
Other common reasons include anti-virus; firewall; not having appropriate operating system level permissions; in Windows - using a Domain-based userid instead of a local administrator; and just general finger issues.
Express is considerably different in the install behaviour and runtime behaviour. For example. it uses RPM and MSI instead of Oracle Universal Installer. It does not include Java in the database, which limits a lot of functionality. And it uses the built-in PL/SQL Web Gateway instead of any external HTTP server. As a result, it can be quite a shock to mmany of the regular inhabitants in this forum.
I strongly encourage reading the documentation for XE. In particular, reading the install doc. Start at http://tahiti.oracle.com and look for the Oracle Database 10g Release 2 Express Edition documentation. (Just below the Oracle Database 10g Release 2 documentation.)
