I just trying to import some informations from excel to Oracle using OLE2 over Oracle Forms 6i, but It´s very slow when I have import under then 10k lines. anything to optimize that ? Follow the code used...
application OLE2.Obj_Type;
workbooks OLE2.Obj_Type;
workbook OLE2.Obj_Type;
[Code]....
I am using OLE2 to update an excel spreadsheet from Oracle Forms 6i. If the excel spreadsheet is already open, the code runs through fine, and even asks if you want to replace the file when running the lines: OLE2.INVOKE(worksheet, 'Save');
OLE2.INVOKE(workbook, 'Save');
However, the file never gets updated. There is no error that appears. I would like to have the program check if the file is open before running the program;
Im trying to display a word file from a blob column of table in reports 11g . In reports 6i OLE2 file format was available for that, but in 11g it became obsolete.
View 1 Replies View RelatedI need to read data from text file(located on application or db server or on some other server, however path is known to me.) and then append some data in it.
Data will be read and written on daily basis so i want to clear all data on date change.
I know that this topic in not new, but maybe my case is a bit different than common.My form has multi-record block (4 columns) in which i want to upload CSV file.
The form will have "Browse..." button to piont CSV file (on local users disc, not where Forms server resides) after pointing the CSV file, user will press UPLOAD button which will import CSV data into block. After that data is visible in block. But whole form must not be refreshed.
I'm studying about UTL_FILE package, but it seems it allows manipulating files on server not local user's machines. Do Forms have such "Browse... -> UPLOAD" possibility or I need to learn Java and create Java funcionality inside Forms?
Or it is impossible to load data directly into form? (I have to use SQLoader and load data into temp table then into block on form????)
I have a Excel File which contains some columns and rows, i need to load that excel into a form and import that form data to Database Table, using DDE Method.
In simple i say; Just to read the excel and load into a form, which can be imported into a table later.
How to achieve this? only dde method.
I need some one provide me with doc, pdf, ppt, notepad anything to understand how to use OLE2
I know you will say search in this forum or google it i already search it and google it but all of them are examples or a questions for specific requirement. No one explain how is this code work even oracle it self check this link

For example, we have a table ACCOUNT (snowflake dimension containing other dimension keys) and I have many fact tables based on this dimension. Normally data warehouse load happens like first dimensions needs to be loaded and then facts. Our frequency of loads is 30 mins.
To increase the rate in which the data will be available in the facts (as its a financial application), am considering to have two batches one with dimension and another one with fact (came to this conclusion as there is no dependency like first dimensions to be loaded then only fact) just the update might get missed sometimes. But if I do that, when dimension gets loaded, it will be read in the facts in another session. Will this affect the performance ?
LOADING (insert/update) and selecting data from table at the same time. Will it affect the performance in any way.

I'm trying to utilize the utl file to read a txt file and import the data into a table in Oracle. I've read in various forums and have researched a lot on oracle documentation site and on the internet but can not find the answer to the problem.
The source follows:

dbms_output.put_line (Linha);
End Loop;
UTL_File.Fclose (arquivo_ler);
DBMS_OUTPUT.PUT_LINE ('File processed with sucesso.');
END;

The errors:

we are busy updating one databasee from a windows platform 2003 oracle 10G to a linux and oracle 11r2
We exported/imported the data and it looks ok Explain plans look the same . but our heavy batches are twice slower than on the windows box ,the two top events are disk related, sequential and scattered reads there are 90% of the time of the batch job , i read some white paper and found that using ASM can be bad in some cases the same with the linux for this particular kind of scattered reads , i was just wondering if just changing the SGA to 10GB instead of 4GB to get more cache and speedup the things .

working on loading the data from flat file into table and below given is the validation condition given.I checked the UTL_FILE build in package but not able to figure out, how to identify the column header in flat file.
1. Skip the header, if any. The header is the first record, and starts with '000'
2. Skip the trailer, if any. The Trailer is the last record, and starts with '999'
3. Log an error, but continue if a line exceeds 512 characters
4. Log an error, but continue if a line is blank
I am porting data from database to word document.Initially i am creating the table using the following
hSelection := OLE2.GET_OBJ_PROPERTY(hApplication, 'Selection');
hTables := OLE2.GET_OBJ_PROPERTY(hDocument , 'Tables' );
hRange := OLE2.GET_OBJ_PROPERTY(hSelection, 'Range');
args := OLE2.CREATE_ARGLIST;
OLE2.ADD_ARG_OBJ(args, hRange); --Range
OLE2.ADD_ARG(args, 26); --NumRows
OLE2.ADD_ARG(args, 4); --NumColumns
OLE2.ADD_ARG(args, wdWord9TableBehavior); --DefaultTableBehavior
OLE2.ADD_ARG(args, wdAutoFitContent); --AutoFitBehavior
hTable := OLE2.INVOKE_OBJ(hTables, 'Add', args);
But i want to change the columnwidth. As you see above i have 4 columns, in that first column should be double than other column.
peice of code to change th ewidth of column in word document.
When I click on excel report button on the parameter form, the excel runs behind the form instead of in running in fron of it thereby making it partially invinsible. I am having to minimise the form to have a clear view. This is not the case with Forms 10g. Is there an extra code on the OLE2 to send the form to the background so that the excel output can take over the screen.
View 6 Replies View RelatedI am trying to insert huge data into another huge table which is almost taking around 2-3 hrs. See my below query
INSERT /*+ APPEND *//*+ NOLOGGING */ INTO DB1.Table1 SELECT * FROM DB2.Table2 ;

We have a MV which fetches data from around 27 tables containing 26 joins out of which 25 are outer joins. Some tables in the query are being referred multiple times through different alias names and hence the actual no of physical tables used is 18. This MV takes about 50 mins to refresh through complete refresh mechanism. We decided to make it fast refresh and thus made these configurations:
- Created MV logs based on rowid for each of the base tables.
- Recreated MV using FAST refresh,with primary key option enabled
- Pulled rowid for all these tables in the select column statement.
Even after making all the recommendations suggested by Oracle for fast refresh MV's we are still getting refresh time of around 65 mins(refresh time increased!!!).We already have indexes built on all the join columns of the base tables. What else do we need to do to make this a "fast" refresh MV ?
I'm extracting/retrieving the data from the oracle database using Java application it's bit slow. However, when I retrieve from the SQL server it's faster than oracle.

The product I work on requires a query to tell us what tables are dependent on certain types.
SELECT dba_tab_cols.owner,
dba_tab_cols.table_name,
dba_tab_cols.data_type_owner,
dba_tab_cols.data_type
FROM dba_tab_cols
JOIN dba_types
ON dba_types.owner = dba_tab_cols.data_type_owner
AND dba_types.type_name = dba_tab_cols.data_type
WHERE (dba_types.owner IN ('SCHEMA1', 'SCHEMA2'......))
I find this query to be pretty slow. I think it is because data_type_owner in dba_tab_cols is not indexed. Adding an index is not an option because users expect our product to read-only.
