We are designing a three tiered system (client, application/web server, database server) that will allow clients through a web interface to select a text file from the operating system and load that file into a intermediate table (import database table). Many users will do this concurrently and data will load into a single table. The text files come in monthly for about 100 firms. No user is able to insert or update the data of another users data (there is a check out system). Their are about 30 to 40 users that will be using the system doing various functions but it is possible for 10 to 20 users to import data at one time. The files can have anywhere from 2000 to 25000 records at a record length of 398.I am concerned about having a good design strategy as well as decent performance.
Problems with each of the Oracle loaders.
1) External tables - Can not read data text files on the application server(which is where they want the text files to go) secondly you cannot create a instance of a external table. Multiple users will be using the external table to point to different text files and loading at the same time.
2) Sqlloader - is mainly a OS level tool and I am not sure how I could programatically point it to a different text file each time a user wants to load. The client will have to have the ability through code to point sqlloader to the correct file name.
I had a creative approach and was wondering if this would work. I would like to use external tables just like a connection pool. I would propose first a scheduled OS job to move files to the database server. I would create about 20 external tables with 20 different directory objects. Using a stored procedure for the user to call and pass in file name and audit info as needed. I would use a Load lock pool table (my invention) to load the name or a code for the external table in use. The procedure loads this code into my load lock pool table when a external table is in use and deletes the name when the load is completed. The procedure would check through a series of if statements whether a particular external table was in use. If in use (exist in load lock pool table) I would check the next available external table until a external table not in use is encountered. Now potentially 20 users at one time but not likely would be laoding into the same table at one time.My questions
1) Could Oracle handle this strategy? What do I need to consider performance wise with the possibility of so many users loading into a single table at one time?
2) Do any of you maybe have another strategy to do this?

I have written a below procedure to dump the table data to .csv file.But the problem is i have 20 tables which is holding 75 studies data. Means every table will have 75 studies related data.what i supposed to do is i need to export the data from 20 tables for each study. but this procedures requires me to run the procedure 75(studies)*20(tables) times. is there any technique instead of i manually giving the table name and study name , will it take from any text file where we defined 75 studies in that. or easy there any better way .
create or replace procedure dump_table_to_csv1(p_tname in varchar2,
p_dir in varchar2,
p_filename in varchar2)
is
l_output utl_file.file_type;
l_theCursor integer default dbms_sql.open_cursor;
[code]........

I'm trying to create an install script to install Discoverer 10g R2 with its needed patch and opatches applied without any user interaction. I've already created the necesary response files and a batch file to sequence it. The installer should work when the it is placed on a server with the main folder shared and it does so flawlessly.
the user sees a dos window which is kindly stating that he has to wait for the primary installer to finish before hitting enter to start the patch installer.The problem I'm having is that, on slow networks, it takes a while for the primary installer of discoverer 10g to show up a window and of course the user isn't always patient enough to wait for it and hits enter before the primary installer is showing itself causing the patch installer to start before discoverer is completely installed.
Is there a way to avoid this? Or am I wrong in using a batch file to sequence this install? second problem is the needed interaction while applying opatches, can this be automated as well?
here is the contents of my batch file:
net use x: /delete
net use X: \\servername\Oracle_cd\disco10gr2 /persistent:no
@ECHO off
cls
:start

We have two databases one localdb with user rakdb and another one remotely remotedb with user rakdb .We need to be in sync with data in one table called om_item, where the users are inserting data on daily basis and the user sends us the insert script everday to run it on local databse to insert the new records in local database.I managed to create a file which records all the inserts into one text file in one directory.Can we have a scheduler to pick this text file from the specified folder and send mail using utl_mail.
CREATE TABLE ITEM (IT_CODE VARCHAR2(12),IT_NAME VARCHAR2(20));
INSERT INTO ITEM VALUES ('A','AAA');
CREATE OR REPLACE DIRECTORY MY_DIR AS 'C:TEMP';
CREATE OR REPLACE PROCEDURE it_status
[Code]..
Procedure created.
EXEC it_status
HOST TYPE c: empaaaa.txt
INSERT INTO ITEM (IT_CODE, ITEM_NAME) VALUES ('A','AAA');
COMMIT;

I have a proc created which dynamically creates scripts to be executed, e.g. using DBMS_OUTPUT.PUT_LINE it creates the following scripts to be executed:
EXEC D_Q_TST1('PARAM1','PARAM2','PARAM3');
EXEC D_Q_TST2('PARAM1','PARAM2','PARAM3');
EXEC D_Q_TST3('PARAM1','PARAM2','PARAM3');
EXEC D_Q_TST4('PARAM1','PARAM2','PARAM3');
EXEC D_Q_TST5('PARAM1','PARAM2','PARAM3','PARAM4','PARAM5');
Now, what I am really looking for is to explore options where we can spool the results into a file and run another proc to execute all of these proc through it.
let me know if my request is not clear.

I have migrated database from postgresql to oracle...All sequences are migrated with their default values...(Start with 1) I already have 213 entries in a table and I want to begin using this for 214th entry ( replace with "start with 214")
How can I automate the process of updating "Start with" value of sequence with the max no of entry on my table every time I migrate data....
I have created a trigger that will automatically insert the next number from the sequence into the id column.
create trigger test_trigger
before insert on test
for each row
begin
select test_seq.nextval into :new.id from dual;
end;

I have been plagued by people logging into my database and making changes when a clone is in process.. Having said that ,I am looking to lock accounts and unlock them when I am done.
I envision my code looking something like this:
sqlplus -s / <<END
SET PAGESIZE 0
SET FEEDBACK OFF
SET VERIFY OFF;
set heading off;
spool /tmp/lockusers.sql
select 'alter user ' || username || ' account lock;' from dba_users where username not in (....) and not locked?;
spool off;
END;
sqlplus -s / <<END
@/tmp/lockusers.sql
END;
When it comes time to unlock the accounts I want to be able to unlock those accounts I previously locked and not all of them. Is there a query, I can use that can tell me when the accounts were locked or some other way about going about this so I dont unlock accounts that were locked prior to my lock script running?

My client has asked me to provide production data from a xyz table into excel.The constrain for the same is that he needs the data for a particular month within a specific range of dates.
Is this possible using oracle utilities like SQL developer, plsqldeveloper or toad or any other. If yes i want to know if this is possible without using the same?

I found another way to transfer the data from forms to excel apart from doing it through ole2 or client. So thought of sharing it with all...
Here it goes:-
declare
ifile client_text_io.file_type;
temp varchar2(1000);
Cursor c1 is select ename, job from emp;
[Code]....
Attach webutil to form and just paste the code on a button and log on to scott. The excel file will be created in c: drive with name test.

My database is 11.1.0.7 and 11.2.0.3 with TDE tablespace encryption, ASM db storage. The wallet needs to be opened for MRP to work in physical standby database. I already have the solution for the primary instances to automate wallet open (e.g. using startup trigger for 11.1.0.7). However, I cannot find solution to automate wallet open operation in standby instances (to issue ALTER SYSTEM SET ENCRYPTION WALLET OPEN IDENTIFIED BY ""').
Manual operation everytime standby instance is started is not feasible.
