Populate the database from a file

Hi guys,
I have to populate an Oracle database using a java standalone application. The application gets the data from a file and copies them into the database. I don't know how to structure the entire thing and in which layer (view or model) i have to implement this functionality.
thank's a lot,
christian

either you configure FOP to use a SAX Parser that supports Cp1251 or you encode your XML data to UTF-8.
we flawlessly generate Greek PDF documents out of data selected from Oracle 8.1 by using UTF-8.

Hi Venkat,
I think this isn't the best forum to answer your question but I'll try.
You've lost your DATABASE FILES (means DBF files, control files (CTL), redo logs)? Correct?
Or did you loose also the Oracle Home where the software has been installed?
If you've lost your Oracle installation than you might do the following:
1) Install 8.1.7.0 software on your standby server
2) Install patch set 8.1.7 4 into this home
3) Metalink-Note:70233.1 will describe the full process of creating an 8i standby database from your PROD.
If you use RMAN than please have a look into Metalink-Note:203980.1 and Note:118409.1 - it'll describe also the init.ora parameters necessary for a standby
You'll find a description of an ideal init.ora for the standby in ML Note:139809.1 and specific for Data Guard 8i here: ML-Note:132991.1
Kind regards
Mike

Hi,
you can try to use the:
ConsumerTreeListPreview
layout for KM navigation ivew (or customize to your own).
This layout shows a folder tree on the left, a document list on the right. When you click on a document from the list it shows the contents of the file on the bottom of the iview.
Hope this helps,

Use LINQ to extract the data from a file...

Hi,
I have created a Subprocedure CreateEventList
which populates an EventsComboBox
with a current day's events (if any).
I need to store the events in a generic List communityEvents
which is a collection of
communityEvent
objects. This List needs to be created and assigned to the instance variable
communityEvents.
This method should call helper method ExtractData
which will use LINQ to extract the data from my file.
The specified day is the date selected on the calendar control. This method will be called from the CreateEventList.
This method should clear all data from List communityEvents.
A LINQ
query that creates CommunityEvent
objects should select the events scheduled for selected
day from the file. The selected events should be added to List
communityEvents.
See code below.
Thanks,
public class CommunityEvent
private int day;
public int Day
get
return day;
set
day = value;
private string time;
public string Time
get
return time;
set
time = value;
private decimal price;
public decimal Price

return price;
set
price = value;
private string name;
public string Name

if (eventComboBox.SelectedIndex == 1)
descriptionTextBox.Text = "4.30PM. Price 00.00. Take part in cleaning the local Park.";
if (eventComboBox.SelectedIndex == 2)

Any help here would be great.
Look, you have to make the file a XML file type -- Somefilename.xml.
http://www.xmlfiles.com/xml/xml_intro.asp
You can use NotePad XML to make the XML and save the text file.
http://support.microsoft.com/kb/296560
Or you can just use Notepad (standard), if you know the basics of how to create XML, which is just text data that can created and saved in a text file, which, represents data.
http://www.codeproject.com/Tips/522456/Reading-XML-using-LINQ
You can do a (select new CommunityEvent) just like the example is doing a
select new FileToWatch and load the XML data into the CommunityEvent properties.
So you need to learn how to make a manual XML textfile with XML data in it, and you need to learn how to use LINQ to read the XML. Linq is not going to work against some flat text file you created. There are plenty of examples out on Bing and Google
on how to use Linq-2-XML.
http://en.wikipedia.org/wiki/Language_Integrated_Query
<copied>
LINQ extends the language by the addition of query
expressions, which are akin to
SQL statements, and can be used to conveniently extract and process data from
arrays, enumerable
classes, XML documents,
relational databases, and third-party data sources. Other uses, which utilize query expressions as a general framework for readably composing arbitrary computations, include the construction of event handlers[2]
or
monadic parsers.[3]

How can i retrieved data into the infocube from archived files

hi,
i have archived cube data and i have to load data into the cube from archived files.
so now i want to find archived files and how to load data into the cube.
thanks

Hi.....
Reloading archived data should be an exception rather than the general case, since data should be
archived only if it is not needed in the database anymore. When the archived data target is serving also as a
datamart to populate other data targets, Its recommend that you load the data to a copy of the original
(archived) data target, and combine the two resulting data targets with a MultiProvider.
In order to reload the data to a data target, you have to use the export DataSource of the archived data
target. Therefore, you create an update rule based on the respective InfoSource (technical name 8<data
target name>). You then trigger the upload either by using Update ODS data in data target or by
replicating the DataSources of the MYSELF source system and subsequently scheduling an InfoPackage
for the respective InfoSource
If you want to read the data for reporting or
control purposes, you have to write a report, which reads data from the archive files sequentially.
Alternatively, you can also use the Archiving Information System (AS). This tool enables you to define an
InfoStructure, and create reports based on these InfoStructures. The InfoStructures define an index for
the archive file data. At the moment, the archiving process in the BW system does not fill the
InfoStructures during the archiving session automatically. This has to be performed manually when
needed.
Another way of displaying data from the archive file is by using the Extractor checker (TCODE RSA3).
Enter the name of the export DataSource of the respective data target (name of the data target preceded
by 8), and choose the archive files that are to be read. The extractor checker reads the selected archive
files sequentially. Selection conditions can be entered for filtering but have to be entered in in internal
format
It will remain same in the change log table.

How to transfer the tables from one file group to another file group in SQL 2008.?

Hello all,
I have few issues regarding the transfer of the tables from one file group to another file group  in SQL 2008 and also How can we  backup
and restore the particular database based on file group level.
Let’s say I have a tables stored within the different FG. such as
Tables
  File group
Dimension tables
Primary
Fact tables
  FG1
FG2…
zzz_tables
  DEFAULT_FG
dim.table1                                                                                                                          DEFAULT_FG
dim.table2                                                                                                                          DEFAULT_FG
Here all I want to transfer the dim.table1 ,dim.table2  from  DEFAULT_FG to the Primary File
group .So is there simple methods for transfer the dim.table1,2  from one FG to another .I have tried somewhat but I couldn’t get the exact way .So if someone have better idea please share your knowledge that would be really appreciated.
Secondly after moving those dim.table1 ,dim.table2 from DEFAULT_FG to Primary ,All I want to backup and restore the database only containing  the Primary and FG1,FG2… not
a DEFAULT_FG.Is it possible or not.?
Hope to hear from the one who knows better approach for this kind of task .Your simple help will be much appreciated.
Regards,
Anil Maharjan

Well after all my full day research on this topic had paid off, I finally got the solution and am so happy to research on these things. It makes
us feel really happy after all our research and hard work doesn't goes as waste.
Finally I got what I am looking for and want to make sure that I am able to transfer the tables from DEFAULT_FG to another FG without tables
having clustered index on that tables .
With the help of the link below I finally got my solution where Roberto’s coded store procedure simply works for this.
Really thanks to him for his great post and thanks to all for your response and your valuable time.

Wrong century for the dates from flat file

I am in the process of uploading the data from flat file ( aka CSV) into oracle via external table .
All the dates have the year of 20xx. My understanding was 51-99 will be prefixed with 19 ( such as 1951 - 1999) and 00-50
will be prefixed with 20 ( such as 2004 ... )
The column below ( startdate ) is of timestamp .

URGENT,FRM-41337: Cannot populat the list from record group

Hi all:
Can anyone help me in that problem?
I have a database item in the block as a list item with combo box style and I use this code in WHEN-NEW-RECORD-INSTANCE at the form module level to populate that combo box list:
DECLARE
     group_id RECORDGROUP := FIND_GROUP('group');
     list_id ITEM := FIND_ITEM('employees.job_id');
     x number;
BEGIN
IF NOT ID_NULL (group_id) THEN
          DELETE_GROUP (group_id);
     END IF;
          group_id := CREATE_GROUP_FROM_QUERY ('group','select name,TO_CHAR(id) job from cmn_jobs where job_type_id = 4720 ');
     x := POPULATE_GROUP (group_id);
     POPULATE_LIST (list_id, group_id);
     EXCEPTION
WHEN NO_DATA_FOUND THEN
null;
     END;
That code worked very well and without any problem, but when I change the list item from combo box style to poplist style then the forms give that error:
FRM-41337: Cannot populat the list from record group
And an additional null/blanke element appears in the poplist with original element that come from RECORDGROUP.
So can anyone help me to solve that problem please?

First, how I can assign a default or initial value DYNAMICALLY to my poplist.Set the default-value to a parameter like :PARAMETER.MYPARAMETER then you can assign the desired default-value to the parameter.
second, if I have popliste say X for example depend on another poplist say Y ,so when I put the code to populate popliste X on WHEN-LIST-CHANGED on popliste Y and make query then the >forms return FRM-40301 Query caused no records to be retrieved ,but when I have a copy for that code in WHEN-LIST-CHANGED and put it in WHEN-NEW-FORM-INSTANCE at the form >module the form work and returns records, so is it any error or exception in what I did.Can't answer that, you should check :SYSTEM.LAST_QUERY to see why the query does not returnany records.
At the last, which better to put the code for popliste in PRE-FORM trigger at the form module or in WHEN-NEW-FORM-INSTANCE at the form module.I would use the PRE-FORM-trigger

How to startup the database from pfile?

Hi guys.
hope all of you fine.
how to startup the database from pfile?
Thanks.

You can create pfile from spfile
SQL>create pfile='/tmp/pfile.ora' from spfile;
then
SQL>startup pfile='/tmp/pfile.ora';
You can edit pfile.ora file and startup your database with this newly changed database parameter using pfile
And you can define you're using pfile or spfile by issuing:
SQL> show parameter spfile;

# This file is provided by Oracle Corporation to help you customize

# are discussed, and example settings given.
# Some parameter settings are generic to any size installation.
# For parameters that require different values in different size
# installations, three scenarios have been provided: SMALL, MEDIUM
# and LARGE. Any parameter that needs to be tuned according to
# installation size will have three settings, each one commented
# according to installation size.
# Use the following table to approximate the SGA size needed for the
# three scenarious provided in this file:
# -------Installation/Database Size------
# SMALL MEDIUM LARGE
# Block 2K 4500K 6800K 17000K
# Size 4K 5500K 8800K 21000K
# To set up a database that multiple instances will be using, place
# all instance-specific parameters in one file, and then have all
# of these files point to a master file using the IFILE command.
# This way, when you change a public
# parameter, it will automatically change on all instances. This is
# necessary, since all instances must run with the same value for many

Hello All,
I had to reinstall oracle software. But I have all the data\control\log files from previous installation.
So my question is, Can I rebuild my database from those files? If so, how?
All the installation directories are same as before. I don't know if this helps but just wanted to provide as much info as possible.
Thanks,
Satish

All your tablespace, user, grants, etc. information is stored within the system datafile, so if you install the Oracle server, then manually recreate the directory structure from your previous database (for example on NT, you'd create d:\oracle\oradata\your_sid\*.dbf
d:\oracle\admin\your_sid\pfile | bdump | etc...) then put the datafiles in the location where the control files says they should be, and your pfile points to the correct control files then it will be OK.
Your pfile will contain the location(s) of your control files. When you nomount the database, the instance will start and the pfile will find the location/locate the control file (this is why you recreate the control file in nomount mode); then when you mount the database, the control files are actually opened and read so the instance can locate the datafiles, identify the tablespaces, etc (this is why you have to put the control files in the location(s) specified in the pfile and datafiles, etc. back in the location specified in the control file). Then opening the database just basically validates everything and opens for use. As long as you don't specify SIZE or REUSE for the datafiles in the control file, and comment out everything after the CHARACTER SET listed in the control file and you still have the datafiles that contain data, you won't need anything like an import. You may need media recovery of some sort or experiment with incomplete recovery (if files are available) and open with resetlogs; but normally if you have an OracleService and you have a pfile, control files, and datafiles, everything will be there (user info and all is stored in the system datafile).
Hope this helps answer some of your questions. Anyway - you can try it and if it fails, you can always start over as long as you have a backup copy of your datafiles and controlfiles and pfile.

UTL_FILE
With the UTL_FILE package, your PL/SQL programs can read and write operating system text files. UTL_FILE provides a restricted version of operating system stream file I/O.
UTL_FILE I/O capabilities are similar to standard operating system stream file I/O (OPEN, GET, PUT, CLOSE) capabilities, but with some limitations. For example, you call the FOPEN function to return a file handle, which you use in subsequent calls to GET_LINE or PUT to perform stream I/O to a file. When file I/O is done, you call FCLOSE to complete any output and free resources associated with the file.
