Security allows you to decide who should have access to individual files, and whether other users can update them. Searching Files of different types, such as e-mail and word processing files, are stored in separate file systems, so you must perform multiple searches to locate all references to a topic.
Content-based searching is slow and difficult. Multiple file types can be stored together in Oracle i FS. You perform a single search to locate all references to a topic. Content-based searching is not only fast, but sophisticated. As a user of Oracle i FS, it may be useful to you to know how the features of this product can help you do your work faster and with greater convenience.
You don't have to learn a new interface in order to work with files stored in Oracle i FS. Working on a project that includes multiple types of files Unified access to multiple types of data. Using a single interface, you can store and work with many different types of data: - Word-processing files - Spreadsheets - Web pages - Audio and video files - E-mail messages - XML You don't have to deal with separate file hierarchies stored in multiple applications.
All your files, of whatever type, are visible when you open Oracle i FS. Keeping multiple versions of the same file Versioning Versioning lets you automatically save earlier versions of each file, and lets you track the development history of the files.
If you are unhappy with recent changes to a file, you can access an earlier version of the file, rather than trying to recreate the file from memory. While you're working on the file, you check it out; others can read your files, but no one can overwrite your work.
Searching across multiple file types, such as web pages, e-mail, and word-processing files Combined searches Because multiple file types are stored in Oracle i FS, a single search returns a list that includes all file types that match your search criteria.
Backing up data Database-level back up Because Oracle i FS is located in an Oracle database, you can use the data backup and recovery features of the database to protect all of your work files. Web Interface All of the functionality of the Windows interface is duplicated in the Web interface. Figure The Web interface and its three frames The Web interface is divided into three frames.
The Web Folders Hierarchy Using web folders, you arrange content into a hierarchy of folders, just like you do in Windows Explorer. Versioning and check-in and check-out of files are not permitted for e-mail files. Figure E-mail messages copied to Oracle i FS appear in the mail folder FTP Many people use FTP File Transfer Protocol to move their files, especially when uploading revised web pages for publishing on a web server, or bulk uploading files of any type.
IPFS powers the Distributed Web A peer-to-peer hypermedia protocol designed to preserve and grow humanity's knowledge by making the web upgradeable, resilient, and more open. Get started How it works. Get go-ipfs. Get js-ipfs.

Explore the ecosystem Companies and organizations worldwide are building amazing apps, services, and developer tools on IPFS. I'll use P1 and P2 again for the interested and the owner peer.
P1 has a IfsFile instance see library objects below and calls the Download method. This command means the the library wants the server to pull a file from a remote peer. The P2P server gets the remote peer's end point from the command, as well as the file name P1 wants to pull and the folder in which to download the file and then sends a "peer pull" command to the remote peer P2.
P1 now knows exactly how many bytes to accept and starts to receive the bits P2 sends and write them in the destination folder. That's pretty much what a download is. P2P issues to itself the task reader is in another thread a "library push" command. As the peer command listener thread receives the command, it gets the file size and CRC CRC again is not implemented and forms a "peer push" command.
P2 connects to P1 the task contains P1's end point and issues the "peer push" command and starts to stream the file. P1 gets the command, receives the file and stores it in the destination folder, indicated by P2. P2 knows the destination folder, because P1 has sent it in the "push task". That's all. There's a long way to go until you actually start using the library, but we'll get to that stuff Compiling and configuring IFS soon.
The library consists of only 4 classes, that hide everything about peer-to-peer and web services stuff: IfsSystem , IfsPeer , IfsFolder and the IfsFile. In order to use IFS after it is already set up , you should register in the repository as a peer. There's nothing easier than that, like you'll see in a moment, but I'll warn you something first: unless you have registered or logged in as a peer with IFS, you won't be able to use the IFS's most important object - the IfsSystem object.
It is implemented as singleton to avoid having multiple instances of IFS peers on the same peer computer. Of course, you may not register more than one time in IFS unless you're prepared for exceptions , so once you have registered, the next time you should sign in:. Once you've registered or logged in, you can start using the IfsSystem object's properties, the most important and usable of which is the RootFolder property, which returns an IfsFolder object, representing the virtual root folder.
Actually you can perform these actions with all folder objects you get a pointer to, and you can very easily get an arbitrary folder like this:. Below, I am giving some examples of the fore-mentioned operations, and once you've seen them, you can move to some useful static methods of the IfsFolder class.
There may or may not exist other methods either static or instance ones for publishing a folder, but I think these were enough to show you how easy it is done. Now, its time to see what you can do with the published folders:. In the previous version of the article, I forgot to write a lot of things about the files. I forgot to tell you that a file IfsFile has some useful properties:. Again, in the previous article, I mentioned that the IfsFolder has several instance and static methods to publish a folder and a file.
Do you know why the folder should publish a file, and not a file publish itself? Because I was stupid. I was not able to use the IfsFolder class in the IfsFile one, because I would create a cyclic header include. Well, I suck, but let me tell you why. Batched commands. CIFS AndX messages can be chained together and executed in sequence on the server, avoiding multiple message round-trips. The DFS namespace is supported. DFS provides a single consistent object naming scheme a unified namespace that can span a collection of different servers and shares.
CIFS specifies the manner in which clients and servers receive and process referrals. Remote Procedure Call Transport. Message verification. CIFS supports message signing, as described in [KB] , which is used to ensure that messages have not been modified in transit. Unicode file name support. CIFS supports 8. Skip to main content.
