you need to read Oracle Concepts guide to see what information is contained in various db files:

HOW DO YOU CONVET AN ORACLE DATABASE FILE TO A TXT FILE?

Is there a way in a program unit of a form to convert an ORACLE database file into TXT format? When the file gets created, I want to use the text file in a distribution list for sending email. My code in the program unit is:
Insert into THE_IMO_EMAIL
Select distinct imo_email from DS_POC
where imo_email is not null;
commit;
Table THE_IMO_EMAIL is a temporary table. The temporary table gets deleted everytime before records get inserted into it. There is only 1 item in the temporary table.
IMO_EMAIL VARCHAR2(55)
After the COMMIT I want to copy the contents out of the
THE_IMO_EMAIL into a TXT File.
How do I do this? What parameters do I need to use? Should I do this in another program unit?

can you be more clear on this
"DATABASE FILE" what is this? an RDBMS file and you need this in ASCII format. I am lost.

ZFS compression(lzjb) on Oracle Database Files

Hi all,
We have just run few tests with Oracle Database files and using the lzjb compression on zfs with Solaris 10 would bring great space savings. Im looking at 2-3x fold compression ratios on Oracle files. Now, I am aware of slight CPU utilisation (2-3%) on our case, which is nothing compared to benefits.
Raises a few questions tough, are the any cave eats to know about? Why should I NOT turn compression on for Oracle files? From the Oracle Whitepaper I gather that compression is suggested turned on for Archives, but no mention for others.
http://www.oracle.com/technetwork/server-storage/solaris/config-solaris-zfs-wp-167894.pdf
Any suggestions and experiences are welcome

All you need to do is install windows and then oracle 10g.
after the complete installation,shutdown the database.
Now overwrite your previous datafiles including control files and you are done.

Import Oracle Database File Error

Hi Experts,
I got an oracle dump file somefile.dmp today. i dont have any details regarding the dump file but the size is nearly 1.5GB.
I just thought to import that file to my existing Database in local server, the local oracle server details are
Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - Production
PL/SQL Release 11.1.0.7.0 - Production

IMP-00000: Import terminated unsuccessfullyCan some one help me in this?

Thanks for your reply.
I am not clear with this point
- Is the file FTP transferred? Then the possibility is that you used ASCII as transfer mode where BINARY is needed
What i need to do then?.. I need to ask a new dump file with BINARY transfer mode ?Yes.

Oracle Database Licensing Information 11g Release 2 (11.2) - E10594-08

Why does the above document not explicitly state that there are no explicit licensing requirements for Oracle Database client as long as the Database Server is licensed (or if this is wrong then a correct statement) ? This clarity is much needed from a licensing perspective !

Hi,
You are correct: There are no explicit licensing requirements for Oracle Database Client as long as the Database Server is licensed.
This issue has been forwarded to the Database Licensing Guide owners.

DataParser from a set of .cvs files to oracle database

Hello all,
This is my first post here, so I am not sure whether this is the right section of the forum, but anyway..
I need to do a parser that reads cvs files from a set of directories, create a dataset and then a database. I did this as I exported the database to Microsoft Access File. Now, my question is whether it is possible to export it to oracle database file.
I am using C# for the source code. The parser will be run almost every day.
Any help would be appreciated. I have a deadline for the project soon :)

Thanks for the reply.
The situation is the following. I am done with the parsing. I just have two separate classes - MdbExporter and XmlExporter that export the dataset that has been created to a .mdb file or xml one. Here is an example of the MdbExporter class:
class MdbExporter : IExporter
/// <summary>
/// Exportiert das DataSet in eine Mdb-Datei.
/// </summary>
/// <param name="ds">Zu exportierendes DataSet.</param>
public void Write(DataSet ds, string[] names)
string conStr = "Provider=Microsoft.Jet.OLEDB.4.0;" +
"Data Source=" + names[0] + ";";
Console.WriteLine("Exporting to database {0} ...", names[0]);
Now I need a way to export the dataset to an oracle database file.
Thanks for any replay in advance.

Import Oracle DataBase dump file Into Sql Server With out connection oracle using c# code.

Hi All,
I would like to ask how can imports my dump oracle database file data and struct into sql server 2005
with out make connection oracle.
best regards.
Hakim.

Hi Hakim.
Based on your title, what I understood there is a issue regarding transfer oracle db dump to sql database using C# code. Am I right? If so, I am afraid there is no build-in method which meet your requrements in .NET framework. You must provides
OraDump Export API to allow developers integrate corresponding capabilities into their applications. These capabilities are about export data from Oracle dump files into popular databases like Microsoft SQL server. Every developer
having OraDump Export API can write just few lines of code on C# or Visual Basic to implement the appropriate export process.
I am search a third-party link, but it's a paid service.

Oracle Database backup via ESX/VMWare

We are hoping to migrate our SAP systems to Virtual machines running 64bit Linux/Oracle.
We currently use Veritas Net Backup on our HPUX boxes for all our SAP backups, but as we want to go the ESX route it would be nice to perform automated backups (and restores) at the physical server level.
What backup options are there for backing up SAP on a virtual machine?
Is there a backint connection between Oracle/SAP and Veritas Consolidated Backup?
thanks,
Stephen

> We can backup the VMDK files after placing the database in backup mode, so a restore would be to recover this file (or files). But I don't see how this can be automated.
Does that mean you want to put the Oracle database files into VMDK files and not on the raw device/LUN?

Convert flat file to XML document and store into Oracle database

First:
I have a flatfile and created external table to read that file in Oracle
Now I want to create an XML document for each row and insert into Oracle database, I think that XMLtype.
Could you please provide me some information/steps.
Second:
Is there performance issues, because everyday I need to check that XML document stored in the database against the in coming file.
Thank You.

Oracle 11g R2 Sun Solaris
Flat file is | (pipe delimited), so I did create an EXTERNAL Table
row1     a|1|2|3|4
row2     b|2|3|4|5
row3     c|6|7|8|9
I want to store each record as XML document. So it will be easy to compare with next day's load and make insert or update.
The reason is:
     First day the file comes with 5 columns
     after some days, the file may carry on some additional columns more than 5
     In this case I do not want to alter table to capture those values, if I use XML than I can capture any number of columns, CORRECT!. Please make me correct If I am wrong.
     This is the only reason to try to use the XMLType (XML Document)
     On Everyday load we will be matching these XML documents and update it if there is any column's value changes
daily average load will be 10 millions and initial setup will be 60-80 millions
     Do I have anyother option to capture the new values without altering the table.
Please advise!.

Using JDBC Adapter posting data from Oracle database to Falt file????

Hi All,
By using JDBC adapter, for now I have to connect to Oracle Database and then get the employee information from the Employee Table and post it to the flat file, can you please help me out the complete procedure...
Thanks in advance
Andy

Hi Andy,
have a look at the help for configuring a JDBC Sender adapter: http://help.sap.com/saphelp_nw04/helpdata/en/7e/5df96381ec72468a00815dd80f8b63/content.htm
It mentions all the settings you'll need to make e.g. the connection URL as posted above.
And it also lists how an XML file looks like that contains the query results according to the SQL Select statement in the adapter.
<resultset>
<row>
<column-name1>column-value</ column-name1>
<column-name2>column-value</ column-name2>
<column-name3>column-value</ column-name3>
</row>
<row>
<column-name1>column-value</ column-name1>
<column-name2>column-value</ column-name2>
<column-name3>column-value</ column-name3>
</row>
</resultset>
So you have to create a datatype, message type and message interface to match this structure (of course you'll need to substitute column-name1 etc. with the column names in your select statement).
Now if you want to create a flat file from that, you have to create an XML representation of that flat file and use the content conversion in the receiver file adapter as defined here: http://help.sap.com/saphelp_nw04/helpdata/en/d2/bab440c97f3716e10000000a155106/content.htm

Has anyone resolved the problems with using TNSFormat?
As is, I want to move to a shared server setup and to do that I want to use TNSFormat and point to a tns entry which is setup for IPC+Shared connection.
But the Oracle Home that has the Oracle HTTP Server (from the companion CD) does not have SQL*net installed and does not seem to understand TNS.
I have TNS_ADMIN setup, I have ORACLE_HOME_LISTENER poiting to the DB Home.
for the OHS home, using "sqlplus login/pw@ipcshared" works, but "tnsping ipcshared" does not, since tnsping does not exist in the OHS home.
I cannot install SQL*Net from the CD1, since it requires a dedicated/new home and does not want to install in the OHS Home.
The only format that works in a dedicated OHS Home setup is ServiceNameFormat.
Any help or input would be very helpful.
Regards
ps. This is a redhat linux setup.

How to list the JAR files loaded into the Oracle Database ?

How to list the JAR files loaded into the Oracle Database ?

From 11.1 onwards, the below two views are available to identify the jar files loaded into the Database.
JAVAJAR$
JAVAJAROBJECTS$
By querying the JAVAJAR$ view you can know information about the JAR files loaded into the Database and using JAVAJAROBJECTS$ view you can find all the java objects associated with the given JAR file.
These views are populated everytime you use LOADJAVA with "-jarsasdbobjects" option to load your custom java classes.
But unfortunately this feature is available only from 11.1 onwards and there is no clear workaround for above in 10.2 or earlier.

Trying to Attach Files to an Oracle Database Engine

My client performed a complete backup of their Oracle folder (Windows). They simply used Windows Explorer by dragging and dropping the folder on to an external drive. Now that I have the files, I need to know how to "attach" them to my local Oracle database engine. I need to do this so that I can add a new Data Connection in Visual Studio. Or, if I login to the database server, I want to see my client's databases.
Can anyone help me?r

I am used to using SQL Server, which allows you to simply attach database files to a database. I did read some documentation on restoring a database file, but it seemed complicated. Complicated only because you are tying to see it as something it isn't. Please don't take that as a criticism. It's just a statement of fact because you are trying to apply SQL Server thinking to Oracle. Same as trying to apply diesel engine thinking to a gasoline engine.
I thought that there might be a more straight forward solution.
SQL Server isn't Oracle ... by any stretch of the imagination. Even the term "database" refers to totally different concepts. What SQL Server calls a 'database', Oracle calls a 'schema' -- and even that is just a rough approximation.
What you describe in SQL Server sounds a lot like what Oracle would call a 'transportable tablespace', but again that would be an approximation, not an exact one-for-one literal translation.
Where do I get this information? Do you recommend a book or website?The entire Oracle doc set is at tahiti.oracle.com
