There was a need to ensure the Oracle database interaction with the system that can not work with Oracle, but is able to put the files on the FTP -server in the file system. I decided to use the Oracle the XML the DB. With FTP -server focus was not successful, because the system has involved some unsupported command server. He remembered that Windows is able to connect the WebDAV-resource in the form of a drive letter. With this it turned out. So…

In Oracle Standard Edition One, established by default, pre-installed everything you need to run the XML the DB. Tweaking is necessary.

Configuring ACL for TEST_USER user (required in upper case!):

aclxml VARCHAR2 (4000): = 
<Acl description = "All privileges to TEST_USER" 
         xmlns = "" 
         xmlns: xsi = "" 
         xsi: schemaLocation = "  " 
         shared = "true"
                <Grant> true </ grant>
                <Principal> TEST_USER </ principal>
                        <All />
                </ Privilege>
        </ Ace>
</ Acl>

        retb: = DBMS_XDB.CREATERESOURCE ( '/sys/acls/all_test_user_acl.xml', aclxml);

Create a folder:

        retb: = DBMS_XDB.CREATEFOLDER ( '/ home');
        retb: = DBMS_XDB.CREATEFOLDER ( '/ home / test_user');

Assign ACL to create a resource (folder):

exec DBMS_XDB.SETACL ( '/ home / test_user', '/sys/acls/all_test_user_acl.xml');

Create a resource (file) with a certain contents, as follows:

retb: = DBMS_XDB.CREATERESOURCE ( '/home/test_user/intest/2.txt', 'The contents of the new file.');

Delete resource (file):

exec DBMS_XDB.DELETERESOURCE ( '/home/test_user/intest/2.txt');

To see all of the resources in the ” /home/test_user” you can request the following:

SQL> select path (1) from resource_view where under_path (res, '/ home / test_user', 1) = 1;

PATH (1)
-------------------------------------------------- --------------------------------------------------
intest / 1.txt

View the contents of the resource (the file) can be the following query:

SQL> select r.res.extract ( 'Resource / Contents / text / text ()') as text 
  2 from resource_view r
  3 where equals_path (res, '/home/test_user/intest/1.txt') = 1;

-------------------------------------------------- --------

If the user has no authority to the resource, the result will be empty.

Includes support for HTTP on port, such as 8080:

exec dbms_xdb.SETHTTPPORT (8080);

For the FTP :

exec dbms_xdb.SETFTPPORT (2121);

See the FTP – and HTTP IR ports can request:

SQL> select dbms_xdb.GETFTPPORT () ftp, dbms_xdb.GETHTTPPORT http from dual;

        FTP HTTP
---------- ----------
        2121 8080

You can run the following command on the command line of the server:

lsnrctl status

If the pin is an indication of the port 8080, the database means that the port is listening. The output should look something like this:

Listening Endpoints Summary ...
  (DESCRIPTION = (ADDRESS = (PROTOCOL = tcp) (HOST = dbhost) (PORT = 1521)))
  (DESCRIPTION = (ADDRESS = (PROTOCOL = tcp) (HOST = dbhost) (PORT = 2121)) (Presentation = FTP) (Session = RAW))
  (DESCRIPTION = (ADDRESS = (PROTOCOL = tcp) (HOST = dbhost) (PORT = 8080)) (Presentation = HTTP) (Session = RAW))
Services Summary ...

If possible, the HTTP -port better set up on port 80, as WebClient (WebDAV-client under Windows) can not work with non-standard ports. (At least, I could not make it to work.)
If this is not possible, then you need to use some reverse-proxy. We had nginx …
Append location to the configuration file:

location / home {

In our case, the oracle and nginx installed on the same computer.

Now we configure WebDAV support in Windows on a server, on which we need to connect the WebDAV-resource. To do this, add Features. Windows Server 2012 R2 is done as follows:

  • Administrative Tools, Server Manager, Manage, Add Roles and Features, next-next-next to Features
  • Expand User Interfaces and Infrastructure
  • Select and install the Desktop Experience

Then, you must enable Basic Authorization. To do this, edit the registry:

HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ WebClient \ Parameters

BasicAuthLevel” Assign a value of 2.

Many services are running on behalf of the SYSTEM“” and they need to mount the drive in a special way: to create a new Task Scheduler schedule, for example, Mount WebDAV“” with the launch of At startup“” and the implementation of the file, such as C:\map_webdav_drive.bat“”, the contents of which is as follows:

@echo on
net use / delete Z:
net use Z: "http: // dbhost / home / test_user" password / USER: test_user

Connect the disk ” Z:,” resource ” http://dbhost/home/test_user,” c password ” password” out of the user ” test_user.”

Reboot the server. After the reboot, the drive will be connected, but it will only be available to ” SYSTEM“. Accordingly, all services will be able to access it.
