Fragementation of table data in the DB file
Hi,
I am working on an OLTP system where this OLTP is residing on an oracle 10G database[database name ORCL] now further it has got a user OLTP which contains about 50 tables and all these tables are residing physically on a single database file[dbf file] and tablespace OLTP is pointing to this dbf file which is OLTP.dbf, Now there are a certain applications that are front end applications and inserting/updating/deleting in these 50 tables, I am taking a case of inserts so that makes me believe that the individual table data stored in the OLTP dbf file is not getting stored by individual table, now I am facing a lot of performance issues and instead I am trying to fragment data by table, so my questions are:
1) is there a way to fragment data in the physical dbf file such that during the weekend I could go on and fragement the data when the applications are not encountering heavy loads, this is ultimately going to help me with performance issues.
2) is there any way to physically see data in the dbf file since using this information I can solve a lot of my performance issues.
Many thanks
Rahul
Thanks BCV for the link it is very informative.
However I am not concerned about weather some blocks are under utilized or not(the link is actually suggesting a manual way of bringing the data together and I can further pack it up in a plsql procedure with a cursor reading information about my concerned tables by setting up a table with concerned table names), my concern is to bring the reserved blocks for a table together(since inserts will happen on a daily basis on a table and that makes me believe that the blocks reserved will be scattered throughout the DBF file and since they are scattered every time oracle needs to refer a particular table and its full table scan would take more IO on disk if the blocks are scattered throughout the database file as compared to contiguous blocks for a particular table(meaning defragmenting the table data))
PS: I am trying to clear out a few doubts, may be I am not able to understand everything in the link, it would be great if some1 with experience with this kind of activity could throw more light on this topic.
Many thanks
Rahul

Is it possible to view/get the table data from a dump file
I have dmp files generated using expdp on oracle 11g..
expdp_schemas_18MAY2013_1.dmp
expdp_schemas_18MAY2013_2.dmp
expdp_schemas_18MAY2013_3.dmp
Can I use a parameter file given below to get the table data in to the sql file or impdp the only option to load the table data in to database.
vi test1.par
USERID="/ as sysdba"
DIRECTORY=DATA
dumpfile=expdp_schemas_18MAY2013%S.dmp
SCHEMAS=USER1,USER2
LOGFILE=user_dump_data.log
SQLFILE=user_dump_data.sql
and impdp parfile=test1.par.Hi,
To explain more about my situation.
Target database has the dump files, where as the source database (cloud) doesn't have access to the target database.
However, I can request the target DB DBA team to run the par files and provide me the output like a SQL file which I can take and run it in my source database.
I got the metadata the same way, but is there any way I could get the data from the dump files on the target DB without actually accessing it? My question might sound weird, but please let me know.
<
1. export from the source into a dumpfile. You can do this on the source database and then copy the file over to your local database or you can do this from a local database if you have a database link defined on the local database that points to the source database. In the second case, your dumpfile will be created on your local database.

How can i access the dump using the database link? -
How can we export table data to a CSV file??
Hi,
I have the following requirement. Initially business agreed upon, exporting the table data to Excel file. But now, they would like to export the table data to a CSV file, which is not being supported by af:exportCollectionActionListener component.
Because, when i opened the exported CSV file, i can see the exported data sorrounded with HTML tags. Hence the issue.
Does someone has any solution for this ... Like, how can we export the table data to csv format. And it should work similar to exporting the data to excel sheet.
For youre reference here is the code which i have used to export the table data..
><f:facet name="menus">
><af:menu text="Menu" id="m1">
><af:commandMenuItem text="Print" id="cmi1">
><af:exportCollectionActionListener exportedId="t1"
>title="CommunicationDistributionList"
>filename="CommunicationDistributionList"
>type="excelHTML"/> ---- I tried with removing value for this attribute. With no value, it did not worked at all.
></af:commandMenuItem>
></af:menu>
></f:facet>
Thanks & Regards,
Kiran KonjetiHi Alex,
I have already visited that POST and it works only in 10g. Not in 11g.
I got the solution for this. The solution is :
Use the following code in jsff
==================
<af:commandButton text="Export Data" id="ctb1">><af:fileDownloadActionListener contentType="text/csv; charset=utf-8"
>filename="test.csv"
>method="#{pageFlowScope.pageFlowScopeDemoAppMB.test}"/>
></af:commandButton>
OR
<af:commandButton text="Export Data" id="ctb1">><af:fileDownloadActionListener contentType="application/vnd.ms-excel; charset=utf-8"
>filename="test.csv"
>method="#{pageFlowScope.pageFlowScopeDemoAppMB.test}"/>
></af:commandButton>
And place this code in ManagedBean
======================
> public void test(FacesContext facesContext, OutputStream outputStream) throws IOException {
> DCBindingContainer dcBindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
>DCIteratorBinding itrBinding = (DCIteratorBinding)dcBindings.get("fetchDataIterator");
>tableRows = itrBinding.getAllRowsInRange();
preparaing column headers
>PrintWriter out = new PrintWriter(outputStream);
>out.print(" ID");
>out.print(",");
>out.print("Name");
>out.print(",");
>out.print("Designation");
>out.print(",");
>out.print("Salary");
>out.println();
preparing column data
> for(Row row : tableRows){
>DCDataRow dataRow = (DCDataRow)row;
> DataLoaderDTO dto = (DataLoaderDTO)dataRow.getDataProvider();
>out.print(dto.getId());
>out.print(",");
>out.print(dto.getName());
>out.print(",");
>out.print(dto.getDesgntn());
>out.print(",");
>out.print(dto.getSalary());
>out.println();
>}
>out.flush();
>out.close();
> }
And do the following settings(*OPTIONAL*) for your browser - Only in case, if the file is being blocked by IE

Exporting Table data to delimited txt file

Exporting table data to a CSV file
hello everyone,
i need help on exporting table data to a CSV file.
I have a div element containing the table which displays some data.
there is a "Export" button just above the table, which if clicked, will export the current data in the table to a .csv file.
can this be done in jsp? or i need to use servlet?
also how can i submit the table data only? (as my webpage contiain other data also)
can anyone provide with some sort of sample code?
thanks in advance!!oops!!
i just forgot..
when the user will click on the export button, i want to greet him with a "Save As"
popup, so that he can specify the filename and location to save the file.
thanks!! -
How to fetch the relational data from the xml file registered in xdb
Hi,
I have to register the xml file into the xdb repository and i have to fetch the data of the xml file as relational structure through the select statement .
i used the below query to register the xml file in xdb.
DECLARE
v_return BOOLEAN;
BEGIN
v_return := DBMS_XDB.CREATERESOURCE(
abspath => '/public/demo/xml/db_objects.xml',
data => BFILENAME('XML_DIR', 'db_objects.xml')
COMMIT;
END;
Now i have to fetch the values in the xml file as relational data .
whether it is possible ?
can any one help me.
Regards,
suresh.When you transform your XMLdata to a xmltype you can do something like this for example:
select
extractvalue(value(p),'/XMLRecord/Session_Id') session_id,
extractvalue(value(p),'/XMLRecord/StatementId') StatementId,
extractvalue(value(p),'/XMLRecord/EntryId') EntryId
from
table(xmlsequence(extract(xmltype('
<XMLdemo>
<FormatModifiers><FormatModifier>UTFEncoding</FormatModifier></FormatModifiers>
<XMLRecord>
<Session_Id>117715</Session_Id>
<StatementId>6</StatementId>
<EntryId>1</EntryId>
</XMLRecord>
</XMLdemo>
'),'/XMLdemo/*'))) p
where extractvalue(value(p),'/XMLRecord/Session_Id') is not null;
For this sample I've put a readable XML in plain text and convert it to xmltype so you can run it on your own database. -
I have a VI and an attched .txt data file. Now I want to read the data from the .txt file and display it as an array in the front panel. But the result is not right. Any help?
Attachments:
try2.txt 2 KB
read_array.vi 21 KBThe problem is in the delimiters in your text file. By default, Read From Spreadsheet File.vi expects a tab delimited file. You can specify a delimiter (like a space), but Read From Spreadsheet File.vi has a problem with repeated delimiters: if you specify a single space as a delimiter and Read From Spreadsheet File.vi finds two spaces back-to-back, it stops reading that line. Your file (as I got it from your earlier post) is delimited by 4 spaces.
Here are some of your choices to fix your problem.
1. Change the source file to a tab delimited file. Your VI will then run as is.
2. Change the source file to be delimited by a single space (rather than 4), then wire a string constant containing one space to the delimiter input of Read From Spreadsheet File.vi.
3. Wire a string constant containing 4 spaces to the delimiter input of Read From Spreadsheet File.vi. Then your text file will run as is.
Depending on where your text file comes from (see more comments below), I'd vote for choice 1: a tab delimited text file. It's the most common text output of spreadsheet programs.
Comments for choices 1 and 2: Where does the text file come from? Is it automatically generated or manually generated? Will it be generated multiple times or just once? If it's manually generated or generated just once, you can use any text editor to change 4 spaces to a tab or to a single space. Note: if you want to change it to a tab delimited file, you can't enter a tab directly into a box in the search & replace dialog of many programs like notepad, but you can do a cut and paste. Before you start your search and replace (just in the text window of the editor), press tab. A tab character will be entered. Press Shift-LeftArrow (not Backspace) to highlight the tab character. Press Ctrl-X to cut the tab character. Start your search and replace (Ctrl-H in notepad in Windows 2000). Click into the Find What box. Enter four spaces. Click into the Replace With box. Press Ctrl-V to paste the tab character. And another thing: older versions of notepad don't have search and replace. Use any editor or word processor that does. -
Create a Purchase order using the BAPI using the data in the XML file.
Hello Gurus,
here is the scenario can anyone help me how to proceed explaining the procedure?
Create a Purchase order using the BAPI using the data in the XML file.
comprehensive explanations are appreciated.
thanks in advance.hi,
first use fm "bapi_po_create".
then use fm "BAPI_ACC_GL_POSTING_POST"
The demo environment was made with real business scenario in mind, but following subjects need to be addressed in a live implementation:
No exceptions and error handling is implemented, except the order rejection (e.g. partly delivery);
In Navision both XML Ports and the XML DOM has been used to integrate with SAP XI, because XML ports has some drawbacks regarding to Namespaces in XML Documents (mandatory in SAP XI);
A minimum of SAP and Navision customization is required to implement this solution. (e.g. user exit in SAP, Navision XML DOM). -
Export table data in a flat file without using FL
Hi,
I am looking for options where I can export table data into a flat file without using FL(File Layout) i.e., by using App Engine only.
Please share your experience if you did anything as this
ThanksA simple way to export any record (table/view) to an csv fiel, is to create a rowset and loop through all record fields, like below example code
Local Rowset &RS;
Local Record &Rec;
Local File &MYFILE;
Local string &FileName, &strRecName, &Line, &Seperator, &Value;
Local number &numRow, &numField;
&FileName = "c:\temp\test.csv";
&strRecName = "PSOPRDEFN";
&Seperator = ";";
&RS = CreateRowset(@("Record." | &strRecName));
&RS.Fill();
&MYFILE = GetFile(&FileName, "W", %FilePath_Absolute);
If &MYFILE.IsOpen Then
For &numRow = 1 To &RS.ActiveRowCount
&Rec = &RS(&numRow).GetRecord(@("RECORD." | &strRecName));
For &numField = 1 To &Rec.FieldCount
&Value = String(&Rec.GetField(&numField).Value);
If &numField = 1 Then
&Line = &Value;
Else
&Line = &Line | &Seperator | &Value;
End-If;
End-For;
&MYFILE.WriteLine(&Line);
End-For;
End-If;
&MYFILE.Close(); You can of course create an application class for generic calling this piece of code.
Hope it helps.
Note:
Do not come complaining to me on performance issues ;) -

How can I show the last amend date of the .rpt file on my report?
I want to show the last amendment date of the .rpt file on my report.
Modification date and time refer to the actual report rather than the .rpt file.
Does anyone have any suggestions? I am using version 11.2.
Thanks,
Anne-Marieannemarier,
Have you tried the "Modification Date" or "Modification Time" fields located under the Special Fields section of the Field Explorer?
I've never used them, but they seem like good candidates.
