UTL package

hey is there any way to check the filename from OS in pl/sql block. if we have a oracle directory named ABC reside physically on c:\backup. backup folder contain 4 different name file like PKMX1, PKMX2.dmp is there any UTL package which enable us to check if filename already there then remove old one create new. i have found UTL package which delete file from directory but how can i check either filename already there or not. plz check this
UTL_FILE package
FUNCTION FOPEN (location IN VARCHAR2,
filename IN VARCHAR2,
open_mode IN VARCHAR2)
RETURN UTL_FILE.FILE_TYPE;

You should use FGETATTR procedure and it's exist parameter to know whether the file exists or not

FGETATTR Procedure
This procedure reads and returns the attributes of a disk file.
Syntax
UTL_FILE.FGETATTR(
   location    IN VARCHAR2,
   filename    IN VARCHAR2,
   exists      OUT BOOLEAN,
   file_length OUT NUMBER,
   blocksize   OUT NUMBER);- - - - - - - - - - - - - - - - - - - - -

eg. i want to use utl.smtp package for sending mails from my forms, but it gives me an error saying that dentifier 'UTL_SMTP.CONNECTION' must be declared
can u please help me.
uday

Hi,
You have to compile the package ORACLE_HOME/rdbms/utlsmtp.sql as sys.
Here is an example on how call/use package utl_smtp:
DECLARE
     smtp_out utl_smtp.connection ;
     PROCEDURE send_header(name IN VARCHAR2, header IN VARCHAR2) AS
     BEGIN
          utl_smtp.write_data(smtp_out, name || ': ' || header || utl_tcp.CRLF);
     END ;
     BEGIN
          smtp_out := utl_smtp.open_connection('smtp.swipnet.se');
          utl_smtp.helo(smtp_out, 'sune.se');
          utl_smtp.mail(smtp_out, '[email protected]');
          utl_smtp.rcpt(smtp_out, '[email protected]');
          utl_smtp.open_data(smtp_out);
          send_header('From', '"Sender" <[email protected]>');
          send_header('To', '"Recipient" <[email protected]>');
          send_header('Subject', 'Test');
          utl_smtp.write_data(smtp_out, utl_tcp.CRLF || 'Hello world!');
          utl_smtp.close_data(smtp_out);
          utl_smtp.quit(smtp_out);
     EXCEPTION
          WHEN utl_smtp.transient_error OR utl_smtp.permanent_error THEN
               utl_smtp.quit(smtp_out);
          WHEN others THEN

EFT Payment Program. Writing to a flat file using UTL Package

Hi guys
I wonder if someone can help me. I'm battling with something in pl/sql. I have a procedure that writes to a flat file. Each procedure I call writes a single section of the file, e.g "create_hdr_rec_line_fn" writes the header on top of the file and "create_std_trx_rec_line_fn" writes the body below the header. Then lastly the procedure that writes the trailer at the bottom of the file.
My problem comes here: I have a proc that calculates the hash total.
This is done by " utl_file.put_line(g_file_id, g_seed_number)". I want to write the hash total next to the trailer section of the file and not below it. How can I do this? Here's the example of the flat file produced. The very last line is the hash total, but I my hash total to be on the same line as the (Trailer). I want it to be just next to the trailer. I hope my question is clear. Please see my procedure below the flat file.
Thanking you in advance....

Hi cdkumar
I'm not quite sure if I understand what you mean. Are you saying that I should use the "PUT" to write 'create_std_trailer_fn' and and then use the "PUT_LINE" to write 'g_seed_number'? Could you please show me what you mean by changing the proc I posted on my question with your suggestions.How about, rather than use code it for you, you try changing the code and giving it a go yourself.
Essentially PUT_LINE will write out the data and put a "new line" character on the end so the next output will appear on the following line; PUT will just output the data without terminating the line, so any subsequent output will just append to the end.
It's very simple. Give it a go.

11g Upgrade - Network ACL

I want to upgrade my oracle 10g database to 11g. the utlui112.sql script shows following -
WARNING: --> Database contains schemas with objects dependent on network packages.
.... Refer to the Upgrade Guide for instructions to configure Network ACLs.
.... USER MDMSYS has dependent objects.
According to documentation , it is not clear whether I need to install XML DB before upgrade or after upgrade to 11g.
I run the following query and result is as follows -
SQL >SELECT * FROM DBA_DEPENDENCIES WHERE referenced_name IN ('UTL_TCP','UTL_SMTP','UTL_MAIL','UTL_HTTP','UTL_INADDR')
AND owner NOT IN ('SYS','PUBLIC','ORDPLUGINS');
OWNER NAME TYPE REFERENCED_OWNER REFERENCED_NAME REFERENCED_TYPE
REFERENCED_LINK_NAME DEPE
MDMSYS MDM_JOB PACKAGE BODY PUBLIC UTL_TCP SYNONYM
HARD
MDMSYS MDM_JOB PACKAGE BODY MDMSYS UTL_TCP NON-EXISTENT
Can someone plaease help on how I can configure the network ACLs?

Hi ,
You can grant to a network and not necessary to grant each machines IP details.
Also this has to be granted to users or the principal is the schema who will be executing this utl_smtp.
If there are multiple users, then you need to grant access to each user.
You need to configure below steps to grant access to the user for utl operations.
This is a new security feature to 11g.
Please review below document :
Oracle® Database Security Guide
11g Release 1 (11.1)
Part Number B28531-06
4 Configuring Privilege and Role Authorization
Managing Fine-Grained Access to External Network Services
URL : http://download.oracle.com/docs/cd/B28359_01/network.111/b28531/authorization.htm#CIHDAJDJ
A example of the setting:
=================
If you are creating the ACL for the first time, you can directly go to step (d).
Please replace the values in < > with your environment values.
a. Drop the user privilege:(please run the below for all the users who are granted connect privilege).
BEGIN
DBMS_NETWORK_ACL_ADMIN.delete_privilege (
acl => '<mailserver_acl.xml>',
principal => '<MYUSER>',
is_grant => FALSE,
privilege => 'connect');
COMMIT;
END;
b. Unassign the network details from ACL (The ip address are only example, please replace with the
values you have specified)
BEGIN
DBMS_NETWORK_ACL_ADMIN.unassign_acl (
acl => '<mailserver_acl.xml>',
host => '<192.168.2.3>',
lower_port => <25>,
upper_port => <25>);
COMMIT;
END;
c. Drop the ACL
BEGIN
DBMS_NETWORK_ACL_ADMIN.drop_acl (
acl => '<mailserver_acl.xml>');
COMMIT;
END;
d. Create the acl again fresh:
BEGIN
DBMS_NETWORK_ACL_ADMIN.create_acl (
acl => 'mailserver_acl.xml',
description => 'Mailserver ACL',
principal => '<MYUSER>',
is_grant => TRUE,
privilege => 'connect',
start_date => SYSTIMESTAMP,
end_date => NULL);
COMMIT;
END;
e. Assign the acl to the network:(please have the ip address modified to correct IP of the machine where this utl package is targetted run.)
for example IP/hostname of mail server should be there for UTL_SMTP to execute.
BEGIN
DBMS_NETWORK_ACL_ADMIN.assign_acl (
acl => 'mailserver_acl.xml',
host => '<192.168.2.3>',
lower_port => <25>,
upper_port => <25>);
COMMIT;
END;
f.Test the package.
Thanks,

Making data in tables online and offline - Backup and Recovery

Hi All,
I'm working on a project where the functionality is similar to 'Backup and Recovery' for database tables.
Lets say we have a set of 6 tables T1, T2.... T6. They do have relationship between them. The tables in questions are simple standard tables, which are not table partitioned.
- I want remove the records from live tables based on user entered date ranges and store it in some offline medium.
- I might want make the data online again from the offline medium; Application should be able use that data without any modifications.
- Different offline mediums can be
a) Flat file
b) Different table space
c) Any other secondary medium (like XML, tape..Etc,)
The total number of records will run in millions.
The proposed solution should consider,
1. Performance - Java solutions not feasible. Anything in SQL, PL/SQL or runs in DB itself(tools) are OK.
2. Reliability - Should be highly reliable, Data corruption simply unacceptable.
3. Security - Users should not be able to make out of the file.
Few options include:
1. Use partition
2. Use SQL*Loader
3. Export and import of tables.
My main targets:
1. Reduce space.
2. Increase performance for queries.
Please pass on your suggestions, any help is highly appreciated!
Thanks In Advance!

Few points to note:
1. I agree partition would be right solution, but as I mentioned in my earlier statement, 'The tables in questions are simple standard tables, which are not table partitioned.'. The tables right now are not partitioned and I believe we cannot add/modify partitions, if the table were not created with the partition option. One work around is to build a partitioned table and copying all the properties(indexes,rows,constraints) from the existing non-partitioned table. But I suspect this is highly riskier and we can't afford to it.
2. I need to support Oracle database versions starting from 8.0.6.
3. Flat file is mandatory, others are optional. I can restrict our discussion just for a file.
4. Considering the above points, the only option I could think of is I can move the records from the table to flat file and remove from tables. When required rollback the file data to the table and application would be able to use it. For export/import few options are: SQL*loader, exp/imp utilities, PL/SQL file UTL packages
Thanks In Advance

Webutil and DB transfer

Is there any chance that DB transfer feature will also be available for previous database server versions, like 8i ?
Or they are missing some functionality required for that ?
As far as I know 8i supports BLOBs and loading files into them...

OK, i did some research on my own and here are my findings (correct me if I'm wrong somewhere):
The only missing UTL package is UTL_ENCODE wchich is used for BASE64 encoding/decoding needed for communication with JavaBeans or something like that.
I have found on Metalink forums thread about missing this functionality in oracle 8.1.7, and someone there provided link to free package which implements it.
Assuming it does it's job right, if I replace in WEBUTIL_DB package calls to UTL_ENCODE with the new one, is it all that needs to get it working ?
Of course I know that by using 3rd-party software code this solution may not be supported by Oracle, but it's better than nothing. Oh, I forgot that webutil is not supported anyway right now :)
BTW, I don't understand why Oracle doesn't want to provide this package for earlier releases, it is simple one and not dependant on new features (I think). Instead when people are asking about this functionality the answer is: "Migrating to 9i is the best and only option"...

XML to CLOB & UTF-8 Queries

I need to create xml files from the available data in the DB tables. I am planning to use SQL/XML functions(xmlroot,xmlelement etc) to construct a well-formed
xml and stored in CLOB data objects. I will use SPOOL command to get the clob (OUT parameter) in my client server (UNIX).
Does any temporary CLOB objects will be created and not cleared by Oracle engine in the table space? If yes,how can i use dbms_lob.freetemporary(clobvar);
to clear the CLOB object after the successful creation and spooling of the xml is done.
I need to have utf-8 character set and achieve url escaped chracters as well, please let me know if these can be done without using UTL_HTTP or any other UTL packages.

Uploading a flat file into Oracle

Hello guys
Can somebody please help me. I've got a flat file that i want to read into oracle via UTL Package. I can read the file successfully if I manually replace the dots with underscores. But when I receive the file, before I upload it into Oracle, it comes in with dots on the file name. eg. The file looks like this: 'IS.DIM16.EFTS.GG24.INTAUD.TEST_20090219105728' then I have to manually replace the dots with underscores to make the file look like this: 'IS_DIM16_EFTS_GG24_INTAUD.TEST_20090219105728'.
I don't want to change it manually. Is there a way to replace the dots with underscores before I read the file? Or is the a way to make Oracle read the dots? I've tried uploading the file with the dots but it gives me this error:
ORA-29283: invalid file operation.
Your help would be greatly appreciated.
Thanks

When i try this, i don't get any error. Can you be more specific ? Code , Expample , OS, version ....
DECLARE
v_handle utl_file.file_type;
BEGIN
v_handle:= utl_file.fopen ('/enspac03/output/ao/in','IS.DIM16.EFTS.GG24.INTAUD.TEST_20090219105728','r');
dbms_output.put_line ('Open');
utl_file.fclose(v_handle);
END;

How to raise the event without creating Triggers

Hi Gurus,
here is my requirement.
Whenever user issue the material from inventory ( on hand quantity reduced ), we have to generate a data file which contains item number, sub inventory and quantity info. for this we have created a utl file package. But here my issue is, without creating triggers / Alerts , i have to run the utl package.
Please advice me how to do this / is there any middle ware tools available to run the package / concurrent prohram.
We are using R12.
Regards,
Sreehari.

Oracle provides various business events for material issue/transactions from inventory (For e.g.,oracle.apps.inv.miscIssue, oracle.apps.inv.subinvTransfer, oracle.apps.wip.job.material.transact, etc.).
First check what kind of transactions happen when the On-hand is consumed. Then Go to any Workflow Admin responsibility >> Business Events: Events >> Search for the event you are looking for >>Hit Update >> Enable the event >> Navigate to Subscription and associate your PLSQL pacakge. let me know if it helps.

U need :
1) To have UTL_FILE_DIR param in the init file of the instance with the same directory (don't forget to stop and restart the base)
2) Handled the exceptions listed in the utl_file package (Oracle_home\rdbms\admin\utlfile.sql) in your source.
3) Turn set serveroutput on in SQL*Plus.
Run your procedure and see the error message to debug.
