I have read the following article:[URL] 11070I want to know wherer if there exists a possibility of write a clob or an xml into a file on disk, if we do not have the CREATE ANY DIRECTORY privilege. Many functions, like UTL_FILE.FOPEN, or dbms_xslprocessor.clob2file, or dbms_xmldom.writetofile, need an Oracle directory to be created (with CREATE OR REPLACE DIRECTORY...). But if we don't have this privilege, is there a possibility to export a clob into a file as xml (the clob contains 100% xml, but this is the column data type, CLOB) if we don't have that privilege?The clob data contains 48200 characters.

In PL\SQL program, I am writing information from one table to file. In my current architecture, I am writing the information to approximately 1000 files.
If I put the database write operation in another package and in another method and call this method from my PL\SQL program asychronously, can that increase performance?

We have a database that is accessed by ArcSDE, a product to modify maps. It uses BLOBs to store those maps.
We ran a load on the server and the response time was slow. By running the following query:
select event, total_waits, time_waited, avg_ms, round(ratio_to_report(time_waited) over () * 100) percent
from (select substr(event, 1, 30) event, total_waits, time_waited, round(time_waited_micro / total_waits / 1000, 2) avg_ms
from v$system_event
where wait_class in ('System I/O') union
select 'CPU' event, NULL, value, NULL
from v$sysstat
where statistic# = 12
order by 3 desc)
where rownum <= 10;
I get
EVENT TOTAL_WAITS TIME_WAITED AVG_MS PERCENT

I'm working on trying to write a shell script to parse a parameter file, but at the same time I want to be able to overwrite the parameter file settings with other command line settings. For instance if my par file had export/import settings for the username, password, schema, etc;
I wanted to run the same export/import with those settings for a different schema. I want to be able to put the schema=<different_than_par_file> after the parfile=<parfile.par and have the parfile be read and applied for everything except the different schema.
Right now I'm storing the cmd line and parsing it again looking for other parameters besides the parfile.

I want to load data to a table and from a simple file text, using a Vb.net application which will connect to a oracle 10g , or a SqlServer or a MySql database, depending the params.
When i connect to a SqlServer Database i use the sql command "BULK INSERT CODPOSTAL2 FROM file.txt with( DATAFILETYPE = 'char',FIELDTERMINATOR = ';', ROWTERMINATOR = '
')"m" and it works fine.
With a DB Mysql i use "LOAD DATA INFILE file.txt INTO TABLE CODPOSTAL2 FIELDS TERMINATED BY ';''" and also works.
My problem is with Oracle. I tried the same example as MySql, but it gaves the error "wrong" ou "unknown command". I also tried in Sql*Plus but it seems to not recognised the command "LOAD".
Another thing, i can't use the Oracle Loader, it must be like this.

How to make the multiple lines of character in single line. Below is the example where i am getting the value when we export the data from the database table.
----------------------
Welcome Aboard customer contact based on Account activation.
The current selection criteria for Welcome Aboard is based at the service level. Therefore, each time a customer connects a service, Welcome Aboard material is mailed to the customer. This is causing the following problems;
Customer complaints. If a service or a number of services are connected on a particular day, it will result in (ie except for some minor exclusions) a single Welcome Aboard pack being sent to each individual customer. As you can expect for corporate accounts, they receive a high volume of this material. Other problems occur when, service/s are deactivated and reactivated, each time a Welcome aboard pack will be distributed.
High costs to Telstra. Each MNET service connected may produce a Welcome aboard pack. This volume of material currently costs Telstra over $500,000 per quarter for Welcome Aboard alone.
