Oracle 11g database Skills testing

Hello,
I want to know, if there exist any system or tool or any real time case study which can I run on oracle database and test my knowledge and skills.
Since I'm at student level and are learning Oracle 11g in deep. Now I want to make a real world database from design to its development and then its deployment in a simulative environment, so to test my knowledge and skill in real scenario. Looking for replies and good suggestions in this matter.
With regards,
Abbasi

What should i do with an Oracle 11g Database, MySQL database and a dump file.

I just joining to a new work field, almost about a database and i know "NOTHING" about this field.
My company has a system that running by Oracle Database, the problem is that Oracle Database will cost a lot of money when my company expands.
So the quest is converting Oracle Database to MySQL database.
Of course i cant try to convert it in the main Database, so i create one Oracle 11g Database on my LocalHost, and it already actived in " Localhost:1158 " etc.
I have another Sever test that already set up MySQL database, and a dump file from the system.
So I want to ask these 2 questions :
1. How to create an new Oracle Database from that dump file ?
2. Is it alright if i use tool to convert Oracle Database into MySql, or i should do it manually ?
Thanks alot.

I predict that converting to MySQL will cost your company more as it expands. As you expand managing contention becomes more important - Oracle does this for you. I do not think MySQL does, so you'll have to write more code to deal with this, costing the company money. A big part of making application scalable and reliable is to use stored procedures, how good are MySQL's compared to PL/SQL's. What other features are there that MySQL has that will benefit your company that Oracle doesn't. What do you need to think about as your company expands that need to be taken care of in the database. I would have thought a migration from MySQL to Oracle would be more common to deal with expansion.
As you know "NOTHING" you need to think about what each database can give you for the next 10 years to cope with you businesses potential requirements, and extimate how much it will cost to implement these requirements, then make the decision

What are the privileges required for explain plan in Oracle 11g database

I am facing the problem in doing a explain plan for a view in Oracle 11g database. When I select from the view like this:
select * from zonewisearpu
It does a select on the view but when I give explain plan like
explain plan for
select * from zonewisearpu
I get the error like insufficient privileges.
Please let me know if things are getting missed out as I guess system level privileges are required to execute this.
I hope, my question is clear.
It’s a humble request to revert urgently if possible as I need to complete a task and do not know the way out.

Thanks for your reply. I have found out that an explain plan is possible on the user's own objects and is not possible on the granted objects from a different schema. For eg, if I do a explain plan on a view querying on tables from a different view, it would not allow the explain plan to proceed. This could mean that explain plan needs different privileges than just a select.
Requesting for a revert to this.
Here is a simple test case that I have perfomed
SQL> create user test1 identified by test1;
User created.
SQL> create user test2 identified by test1;
User created.
SQL> grant connect, resource to test1,test2;
Grant succeeded.
SQL> create table test1.tab1 as select * from v$session;
Table created.
SQL> connect test2/test1
Conencted.
SQL> show user
USER is "TEST2"
SQL>
SQL> explain plan for
2 select sid,serial#,status,username from test1.tab1 where username<> '';
Explained.
SQL>
So, as can be seen I am able to do a explain plan from user test2 for tables belong to user test1.
As far as privileges are concerned, following is the list
SQL> select * from dba_role_privs where grantee in ('TEST1','TEST2') order by 1;

How to monitor oracle 11g database sessions on Windows 2008 server?

Hi Experts
How to monitor the Oracle 11g database sessions on Windows 2008 server (other than SQL Developer tool), which procedure or query is taking more time with Java application.

Recently i found this tool- myorasql on the net to monitor the performence of database, easy to setup and check the performence. i never tested it but seems impresive. It is free and i think it would be use ful to you.
http://myorasql.com/
You can also use Quest - Toad or sqlplus if you are very good at sql commands and all dictionary tables or OEM/EM grid if it is configured .

Establish 32-bit ODBC connection to 64-bit Oracle 11g database

Hi Everyone,
Just to set the scene:
PC with Windows 2003 server x64 OS installed, Oracle 11g 11.1.0.7 64-bit installed and MS Office 2007 installed.
I am looking for advice on the best way to establish an ODBC link so that MS Access 2007 (32-bit) can connect to the Oracle 11g (64-bit) database.
There are known issues, see [http://support.microsoft.com/kb/942976|http://support.microsoft.com/kb/942976] (which I have hit) when attempting to use a 64-bit ODBC DSN within MS Access 2007. This means that I need to setup and install an Oracle 11g 32-bit ODBC driver to be used against the Oracle 11g database (TNS listener also running 64-bit).
Any thoughts on the best approach I should take to do this?
Regards,
Leigh.

The more information section of the MS support article doesn't give me much to go on other than to explain the differences in how user and system DSNs are displayed and managed between the 2 different bit versions of ODBC administrator and how this information is stored in the different registries (64-bit and WOW64).
I have been able to install 32-bit Oracle11g instantclient and its ODBC driver successfully and then in turn create the 32-bit ODBC DSN, however I am unable to connect to the 64-bit database when I attempt to test the DSN. I have updated the Windows PATH environment variable to include both the path of the Oracle11g DB server and instantclient homes as well as creating a TNS_ADMIN environment variable to point to the location of the Oracle11g TNSNAMES.ORA and the 64-bit 11g listener. However despite this I still get the error when testing the DSN:
Unable to connect
SQLState=S1000
[Oracle][ODBC][Ora]ORA-12541: TNS:no listener

Oracle 11g database can we update patch directly from 11.2.0.3.0 to 11.2.0.4.0?

Hi,
I have installed Oracle 11g database.
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
CORE 11.2.0.3.0 Production
TNS for 64-bit Windows: Version 11.2.0.3.0 - Production
NLSRTL Version 11.2.0.3.0 - Production
I want to update the patch.
Oracle 11g database can we update patch directly from 11.2.0.3.0 to 11.2.0.4.0?
Is any impact on the database?
Kindly suggest,
Regards,
Sachin

11.2.0.4 is nothing but a patchset of 11.2.0.3, in-place upgrade is allowed :
http://docs.oracle.com/cd/E11882_01/server.112/e23633/preup.htm#UPGRD12370
"You cannot install the new software into the same location for Oracle home as your current release, unless you are installing an Oracle Database 11g patchset release. For a patchset release, you can use the same Oracle Database 11g Oracle home."
And since it's a patchset, a direct upgrade is ok.
Lastly, yes, every upgrade has an impact (e.g. perf.), it has to be tested.

Want to export with Export: Release 9.2.0.1.0 from Oracle 11g database

hi gurus,
I need to put a user's data from Oracle 11g to Oracle 9i. I heard, I had to do it using exp 9.2, so I installed Oracle 9i client (Export: Release 9.2.0.1.0 ) and tried to export data from Oracle 11g database but I got following character set error while exporting.
"Export done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set"
and exp crashes out.
(env. windows xp)
My questions:
1. may i need to set the character set of oracle 11g database to US7ASCII ?
2. is it reversable process to change character set from WE8MSWIN1252 to US7ASCII ?
3. or there is something else i need to do to get this problem fixed?

Oracle 11g Database Configuration Assistant Hangs At 45% During 1st Install

Platform: Windows Vista 64 Bit Version
Downloaded: Oracle 11g Database 64 Bit
Service Pack 1
Greetings to all my Oracle Seniors. I have been attempting in vain to install the Oracle 11g database software package fully. I was able to complete the initial installation and made it to the second recommended action which was the Database Configuration Assistant operation. After 3 attempts, the progress bar stalled at 45%. I tried to look at the log file cfgtoologs (cloneDBCreation, and CloneRmanRestore), but it said that I didn't have permission. My pre-check cleared OK on everything. So, please direct me as to how to correct this issue.
Thanks
Preston
System Integrator

Well, that is not much of an option right now. I discovered that I have to reinstall the XP Pro OS after attempting the 11g installation 4 times and the install always stalled at 69% during the initial installation. I did have Windows Service Pack 3 installed on the system. I down graded and added 1 G of additional memory and checked the pre-check with no problem. But, the install continued to stall at 69%. So, and, yet, here we are.
Now in regards to the metalink notes, I am new to the forum, so I don't know my way around quite yet. Isn't the metalink the paid suppport option? If so, I don't have that access.

How to mask data in oracle 11g database release 1

how to mask data in oracle 11g database release 1

thx but how i can mask data with above give environment?What does "mask data" mean to you and what is the environment you are referring to?
Telling us that you are using 11.1 helps. But it is far from a complete description of the environment. What edition of the database are you using? What options are installed? What Enterprise Manager packs are licensed? Is any of this changable? Could you license another option for the database or another pack for Enterprise Manager if that was necessary?
What does it mean to you to "mask data"? Do you want to store the data on disk and then mask the data in the presentation layer when certain people query it (i.e. store the patient's social security number in the database but only present ***-**- and the last 4 digits to certain sets of employees)? Do you want to hide entire fields from certain people? Do you want to change the data stored in the database when you are refreshing a lower environment with production data? If so, do you need and/or want this process to be either determinisitic or reversable or both?

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?
We are not licensed for the Oracle Advanced Security Option and I have been tasked to use Oracle Network Data Encryption in order to encryption network traffic between Oracle instances that reside on remote servers. From what I have read and my prior understanding this is not possible without ASO. Can someone confirm or disprove my research, thanks.

Hi, Srini Chavali-Oracle
As for http://www.oracle.com/technetwork/database/options/advanced-security/advanced-security-ds-12c-1898873.pdf?ssSourceSiteId… ASO is mentioned as TDE and Redacting Sensitive Data to Display. Network encryption is excluded.
As for Network Encryption - Oracle FAQ (of course this is not Oracle official) "Since June 2013, Net Encryption is now licensed with Oracle Enterprise Edition and doesn't require Oracle Advanced Security Option." Could you clarify this? Thanks.

Oracle 11g database installation

Hello,
I just want to install the oracle 11g database system in my Archlinux. I've looked the wiki but it's a little bit old.
So has someone tried these days installing it in Arch? How is it going? And the AUR script works?
Another question is how mush size it will be when installed?
Thanks!

I have successfully installed Oracle 11g R2 using the instructions in the Dutch article on the wiki: https://wiki.archlinux.org/index.php/Or … erlands%29 (Google translate is useful).
I had an issue with the db console, but dropping and recreating the repository sorted that out: http://www.bestremotedba.com/how-to-dro … er-in-10g/
