SFTP in PL/SQL

anyone know how to transfer files via SFTP in PL/SQL? Im currently using the UTL_TCP package in oracle to do regular FTP transmissions, but I was told that package doesnt do SFTP. I'm also open to any java classes out there as well, but all I can find so far are ftp-server side java apps.
The server im transferring from isnt a FTP server... just need to transmit and recieve files securely. Anyone know a solution? Let me know. Thanks!

You'll want to go through the Java stored procedures Developer's Guide which talks about things like using the LoadJava utility and creating PL/SQL wrappers around Java classes.
The term "SFTP" is used (often incorrectly) to refer to any of
- SSH file transfer protocol (which is what you seem to be describing and is the correct use of the term)
- FTP over SSH
- FTPS (or FTP/SSL) which is FTP with SSL encryption
http://en.wikipedia.org/wiki/Sftp
Assuming you're using "SFTP" in the most common & correct form, it sounds like you're on the right track.

but now I want to Transfer the same file using SFTP
How do I do the same.

I write PL SQL for FTP

How do I do using SFTP

SFTP through PL/SQL

I have detailed my requirement below and please assist me here.
I need to copy .CSV File from a Windows Server shared path (\\hostname\output) to another server which is on unix.
I will have to use SFTP and not FTP.

Hi,
I'm sure its probably possible using some clever plsql (or c/java) to do this directly from within the database. However it may be easier to just write a batch script which calls an scp/sftp command and transfers the file. This script can easily be called by DBMS_SCHEDULER. winscp is an sftp client but I'm not sure if there is a command line version of it? if not there are plenty of other command line sftp clients - putty (psftp) for example.

Harry

A HOST command in PL/SQL?

Hello guys! :)
I need to execute some SFTP commands on the database server to another SFTP server. In oracle forms theres a built in called "HOST" which executes native commands on the server. Is there something similar to that in PL/SQL?
Also, im wondering of each call of the "HOST" command opens a new session in CMD. I'll need to log in, submit files, and retrieve files as well. If the HOST command opens a new session everytime, ill lose the login credentials from the first HOST command.
Anyone know of anything like this thats been done before? Let me know. Thanks.
Mo

Duplicate thread
SFTP in PL/SQL
Please do not repost if the prior answers don't suit you.
The answer to your question is obviously there is no HOST command in PL/SQL, as there has never been a HOST command, as Oracle happens to be a RDBMS.
You could use the external procedure facility, you could also call Java.
Tom Kyte has an utility for this on http://asktom.oracle.com, called run_cmd

I have followed the steps to the last letter using: Data Loading and the Oracle Database Cloud Service
What I have done on the dashboard and APEX:
I changed the password of the SFTP user.
I have created a new user on APEX that belongs to the SQL Developer Group and changed the 'Require change on Password on First Use' to NO before creating the user
SQL Developer:
I set the database username to the new user I created in APEX
I set the database URL to the URL I used to reach the APEX page...https://databasetrial1875-******.db.us1.oraclecloudapps.com/apex/
I set the SFTP username to the username listed next to 'Service SFTP User Name' on the dashboard
I set the SFTP hostname to: sftp.us1.cloud.oracle.com
I left the port set to 22
When I login on SQL Developer to database, I use the password for the user I created in APEX
Thanks in advance to all who help!

Hi,
You have to use the admin account to add the admin role to the developer account. Can you please try this and let me know of your feedback.
The settings you added look good, and the you have the latest version of Sql DEVELOPER , ...so this should be an issue.
Maybe you have some firewall setting on your computer, that are blocking the connection?
If , after checking all of the above you still have an issue, please contact oracle support via the chat on the cloud.oracle.com and ask the engineer to open a Service Request under your name.
Thanks,
Flori

SQL Developer 4.0.0.13 and Oracle Cloud DB. Cart Access Issue (Unable to deploy in cloud).

Hello,
I asked for a trial account on 04/02 (this year) of the Oracle Cloud. I've been able to create a Cloud Connection in SQL Developer (I'm able to login with my oracle email with the "Service Instance URL"). I am able to see the 11 example tables (DEPT, EMP, and 9 DEMO_X tables).
My data:
SQL Developer 4.0.0.13
DataCenter: US Commercial 2 (US Commercial - Chicago). I'm settled in México, at this moment I don't remember to have selected some DataCenter, but I got that one.
Domain SFTP Host & Port: sftp.us2.cloud.oracle.com:22
Domain SFTP User Name: USdddddd (changed here for example reasons)
Service SFTP Host & Port: sftp.us2.cloud.oracle.com:22
Service SFTP User Name: USssssss (changed here for example reasons)
My problem. I cannot deploy on the cloud (via the Cart tool on SQL Developer).
In chat support, I was told to check this site (1) Data Loading and the Oracle Database Cloud Service. It seems the steps are the same of this site (2) that I was following before Creating and Deploying JSF/JPA Applications to Oracle Cloud.
My scenario is not according the tutorial. According to (1), the tutorial highlights the use of the user detailed as "Service SFTP User Name" (USssssss). The site says that if I click on that user, I should be able to reset its password on SFTP users. BUT, this user (USssssss, Service SFTP User Name) is NOT shown as it is explained, the user that is shown there is the one under "Domain SFTP information" (USdddddd, that is, the user that I should NOT use, according to that webpage).
My user Service SFTP User is not shown in Security-SFTP Users. When I click the user name (USssssss), the site takes you to the Security tab, and SFTP Users sub tab. I notice that my Service SFTP User Name (USssssss) appears in Security tab, but it appears under "Users" sub tab, NOT on "SFTP Users" sub tab. Also, if I try to reset the Service SFTP User password (in Users sub tab), the site says "Oracle Cloud will send an email with a temporary password to USssssss USssssss." It does not ask me to write the new password (SFTP Users sub tab works fine, asking me a password for USdddddd).
Anyway, in SQL Developer, I made several tests in the Cart, testing either the Service and also the Domain users, port 22 and 2222. None of them worked. The message I get is:
Unable to connect to sftp server with provided details.
I've also tried to access the sftp url with Putty, PSFTP, and Filezilla. From those three apps, the sftp url gives me timeout (either on port 22, or 2222). But if ping that url, I got a response back.
So I'm not sure where is the problem. Is it the url? Is it the port? Is it the Service SFTP User? All of them?
Any comment, is very welcome.
P.S. It will be nice to have a "posted date" for each tutorial and perhaps identify the Cloud version that is being explained (the Oracle cloud is growing fast, perhaps the tutorials will be deprecated soon).

Hi Gustavo,
It appears your Service SFTP user was not created correctly. Please contact support and mention the fact that your Service SFTP user appears on Security/Users tab and not on Security/SFTP Users tab.

Bulk Insert from SQL Server to Oracle

I have to load around 20 million rows from SQL Server table to Oracle table using Network Link,wrote following code using Bulk Collect,which is working but taking more time(taking 5 hrs).
I also tried with changing table to parallel degree 8 didn't help(Also Oracle Table set to NOLOGGONG mode).
Is there any better way to do this ? Appreciate any help in this regard .
Script :
CREATE OR REPLACE PROCEDURE INSERT_SQLSERVER_TO_ORACLE
IS
TYPE v_ARRAY IS TABLE OF TARGET_CUST%ROWTYPE INDEX BY BINARY_INTEGER;
ins_rows v_ARRAY;
BEGIN
DECLARE CURSOR REC1 IS
SELECT COL1, COL2,COL3,COL4 SOURCE_SQLSERVER_CUST;
BEGIN
OPEN REC1;
LOOP
FETCH REC1 BULK COLLECT INTO ins_rows LIMIT 5000;
FORALL i IN ins_rows.FIRST..ins_rows.LAST
INSERT INTO TARGET_CUST VALUES ins_rows(i);
EXIT WHEN REC1%NOTFOUND;
END LOOP;
COMMIT;
CLOSE REC1;
END;
END;
Thanks in Advance.

Bulk processing is meaningless in this context. It does nothing to increase the performance - as context switching is not the issue.
The biggest factor is pulling 20 million rows's data via database link across the network. This will be slow by it's very nature.
I would use bcp (Bulk Copy export) on SQL-Server to write the data to a CSV file.
Zip that file. FTP/scp/sftp it to the Oracle server. Unzip it.
Then do a parallel direct load of the data using SQL*Loader.
This will be a lot faster than pulling uncompressed data across the network, a couple of rows at a time (together with the numerous moving parts on the Oracle side that uses a HS agent as interface between SQL-Server and the Oracle database).

WCF-SAP vs SFTP Adapter

Hi All,
We've an existing interface that picks up IDocs from SAP using WCF-SAP adapter, these IDocs contain updates to data that are in turn subscribed by two other SAP systems via couple of Send Ports using the same WCF-SAP adapter. In production we've been facing
performance issues with this design as when there are mass updates in SAP, they push up to 7 to 10K IDocs through, which BizTalk struggles with and that also creates issues for SAP as the queue is not read in quick time which starts building up and creates
issues on the source system.
Now one of the solution proposed for above problem is to use a file based adapter like FILE, SFTP etc. where SAP will publish IDocs as flat files, I believe that'll solve the problem of backlog building on SAP queue and SAP can continue to write files without
impacting by BizTalk not picking them up but would it help in inside BizTalk performance as well? or we'll have to batch the files in using adapter properties (i think it works on SFTP adapter) say take in 100 files every 30 seconds? Any other solution which
can speed this up?
Thanks
Syed

I was just reading this
Restrict the number files Picked up by BizTalk FTP Adapter msdn
thread and it says
"Not possible, the Maximum Files setting only controls how BizTalk creates the message batch
to write them into SQL. This also applies to the File adapters Number of messages in a batch"
So , you need to implement some kind of controller pattern in your solution to manage this floodgate.
Have a read of
How to implement Concurrent FIFO Processing in BizTalk technet wiki article, this for FIFO but this may give some idea to write a controller.

Script Task to Create a ".CSV" file and save it on SFTP.

I have a sql query that is being pulled from a variable. Using this variable I want to create a .csv and save it on SFTP. I do not want to use any third party tools. I really appreciate if anyone can help me with the code. I do not know coding.

The solution Visakh has provided still requires third-party tool. And the proposed tool is not integrated in SSIS.
For a better alternative I would recommend the commercial COZYROC
SFTP Task. It is completely integrated in SSIS and very similar to the standard FTP Task.

Help in PL/SQL

Hello
I have a doub whether the following is possible with PL/SQL
We have a oracle application which stores the data in the DB. We are having a request to transfer a part of this application's data to another applcation which takes care of the finances.
For that we need
1. To create a table that picks data from the DB
2. Put it in a file and
3. Filename has a sequence number – to make sure no files are missed, and files are not processed twice.
4. To have file header contains a batch number – to make sure a batch is not processed twice, and is in sequence, and that the filename has not been changed
5.create checksum for the file
6.finally to transfer the file.
Could you help me to know how to create file in PL/SQL and to create header records, sequence number generation ?
Thanks.

>I have a doub whether the following is possible with PL/SQL
An offensive comment to PL/SQL.. or you do not know PL/SQL at all.
I would not use UTL_FILE.
I would create the entire file as a CLOB (column in a table). Which means the file contents are subject to database security, audting, concurrency, archiving, and all the other good stuff.
I would not create the file directly on the o/s alone. Where it can be accidentally deleted from the o/s by nobody (something which I have seen happening more than once).
Thus I will construct the file as a CLOB and keep it as the master copy. For the file transfer, whether an actual o/s file copy is created depends on whether the transfer is a push or a pull. If a push, I would not even bother writing the CLOB to a physical o/s file - I will push it inside PL/SQL using FTP or HTTP.
If a pull.. if the pull is HTTP, then again PL/SQL wil be used (via MOD_PLSQL) and no physical o/s file will be created. If the pull is FTP or SFTP, then an o/s file may need to be created. But I would first consider using XMLDB for that and the raw FTP session interface - which means the controls are all Oracle and Oracle listener based, with no reliance on o/s utilities and o/s security, and fully portable to any Oracle platform.
I have my doubts if there are anything (in the realm of standard business IS needs) that cannot be done in Oracle.. and PL/SQL.

Implement SFTP in Oracle 8i

Hi,
I have a Stored procedure that generates a file and send it to another server using FTP; but the policies in the company are changing and the FTP must be changed to SFTP. I know that Oracle 8i is not prepared to use this protocol and the migration of the DB version is not an early solution.
Any suggestions?
Thanks.

Since the Oracle database doesn't have a FTP package, if you are doing FTP from Oracle, that would imply that you are using some third party FTP package (of which there are a handful of different implementations). Unfortunately, I'm not aware of any PL/SQL implementation of SFTP.
There are a handful of Java SFTP implemenations. If you can find one that works with the version of the JVM that shipped with your version of 8i (there are three different major releases that fall under the 8i marketing label), you could install and use that. I wouldn't expect, however, to find anything that worked with the ancient JVM in any version of 8i.
If you are doing FTP by calling out to the operating system FTP utility via a Java stored procedure, you could certainly change that call to use SFTP (assuming you find an appropriate SFTP client for your particular operating system, which should be reasonably straightforward).
In general, though, trying to mix relatively modern security requirements with relatively ancient versions of the database is probably going to cause more and more pain over time. You'd really want to consider upgrading to something more recent.

SQL 2008 Agent - run batch file not working

Hello,
I am having some strange issues with a batch file running out of SQL agent I'm hoping I can get some help with.
The batch file's purpose is to send some log files to a SFTP server.
The job has been working great for the past 3 weeks, however this morning it stopped working. The job doesn't error out, however the entire job completes in 00:00:00 duration and I'm given the following message
Date 4/7/2014 3:38:00 PM

C:
cd "C:\Program Files (x86)\WinSCP"
winscp /console /script=G:\Batch\LogTransfer.txt
call G:\Batch\LogTransfer2.bat
echo ** COMPLETED %date% %time% **
echo *********************************
I have numerous other batch jobs running on this server, no other job has had this issue. I have deleted and recreated both the job step and the entire job. I have recreated the batch files from scratch. I have also deleted the entire
contents of the batch file and just simply put in echo **** and still received the message so I'm near positive it has nothing to do with the actual batch file.
I have reset SQL Agent, as well rechecked that the SQL Agent account has run batch rights granted to it.
I moved the batch files to another folder, and they worked for about 4 runs until the same issue happened!!!
The job does execute 100% perfect if I run it manually via batch or if I kick it off starting the job out of SQL.
I am out of options here, does anyone have any ideas that could help me out?
Thanks,
Ryan

Hello,
Try to edit the step, and on the Advanced page of that step try to configure the job to create a log on the location you specify (Output file). Try to run the step again and examine the log created.
Could you try to change the owner of the job to “sa” or to your Windows account? Maybe the SQL Server Agent account does not have access
to the following folders:
G:\Batch\
C:\Program Files (x86)\WinSCP
Alternatively, you can try to create a proxy account.

Hi,
I download the latest version, but when I try to make the connection I always get an "Invalid resource owner credentials". I have given the user admin, user and develop role and can login with the user via the web interface.
Is this path correct? https://database-trialabxn.db.us1.oraclecloudapps.com/apex/
Is there anything else from a security setup I need to do?
