The chunk size for this temporary storage depends on the ultimate storage location. For database tables, the chunk size is governed by the value of the Maximum Attachment Chunk Size field on the PeopleTools Options page. The chunk size in temporary storage can vary, but it never exceeds this maximum attachment chunk size limit. For all other storage locations, the chunk size in the temporary storage table is 16 KB.

The file is streamed from the browser to the servlet on the web server using a standard HTML form construct. Optionally, if virus scan is enabled, the stream in the HTTP servlet request is scanned by the virus scan engine. See Setting Up Virus Scanning. This transfer can be performed securely in an encrypted fashion if the web server uses Secure Sockets Layer SSL to communicate to the browser.

If the HTTP repository resides on a non-PeopleSoft web server, then you need to ensure that the web server can handle file transfer security and requests. System and Server Administration. The URL parameter of the invoked file attachment function includes both the protocol to be used and the address for a storage location. These URLs can be specified as ad hoc strings at run time in certain limited cases.

TXT that is there. Attempting to upload a file called file1. To store file attachments in the database, you must create a target table to store the attachments themselves. This chapter contains additional information on how to create the target table. See Application Development Process Overview.

Then, the application server transfers the file in chunks from the temporary database table to its ultimate storage location. Once the entire file is transferred, the application server deletes the temporary copy from the PeopleTools table in the database.

This section provides an overview of the following: TXT already exists at a particular location on a Windows file system:

So, for example, if a file called FILE1. TXT already exists at a particular location on a Windows file system:. Attempting to download a file called file1.

PeopleCode built-in file attachment functions. These functions operate on and transfer files to and from supported storage locations: PeopleCode provides eight built-in file attachment functions that are organized into three categories:. Use the AddAttachment function to upload one file from an end user specified location local storage or cloud storage to a specified storage location.

CleanAttachments Use the CleanAttachments function to remove orphan files files with no corresponding file reference from specified tables used as storage locations in the current database. CopyAttachments Use the CopyAttachments function to copy all files with file references from one storage location to another. DeleteAttachment Use the DeleteAttachment function to delete a file from the specified storage location.

PeopleTools supports three types of storage locations: Except for the CleanAttachments function, all PeopleCode file attachment functions support all three storage locations. The CleanAttachments function operates only on database tables as storage locations. This section provides an overview of the following:. When uploading to a Windows file system or downloading files from a Windows file system, remember that Windows processes file names in a case-insensitive manner.

Use the MAddAttachment function to upload one or more files from an end user specified location local storage or cloud storage to a specified storage location. Use the DetachAttachment function to download a file from its source storage location and save it locally on the end user machine. The file is sent to the browser with appropriate HTTP headers to cause the browser to display a save as dialog box to the user. Use the ViewAttachment function to download a file from its source storage location and open it locally on the end user machine.

File attachments are supported by using PeopleCode built-in functions that implement the transfer of a file to or from a storage location. Using the PeopleCode functions, files can be transferred back and forth from the end user machine to the storage location by way of the web server and application server or transferred back and forth from the application server file system to the storage location. The following steps depict the process of transferring a file with the AddAttachment function:.

Skip to Main Content. Understanding the File Attachment Functions This section provides an overview of: File attachment storage locations.

Use the PutAttachment function to upload a file from the file system of the application server to the specified storage location. Use the GetAttachment function to download a file from its source storage location to the file system of the application server. Use the CleanAttachments function to remove orphan files files with no corresponding file reference from specified tables used as storage locations in the current database.

MAddAttachment Use the MAddAttachment function to upload one or more files from an end user specified location local storage or cloud storage to a specified storage location. DetachAttachment Use the DetachAttachment function to download a file from its source storage location and save it locally on the end user machine.

If the storage location is a database table, then the chunk size is exactly as specified by the value of the Maximum Attachment Chunk Size field except for the last chunk written, which can be smaller than the maximum. See File Attachment Chunk Size. The file transfer process for MAddAttachment is, in general, similar to the process for AddAttachment.

When the storage location is a database table, the URL parameter of the invoked file attachment function can be specified in one of two ways:. Therefore, if an application will be using multiple FTP user accounts, then care must be take to ensure that files are being stored and accessed in a consistent manner with respect to their absolute location on the FTP server. The default FTP port is If the specified subdirectories do not exist the PeopleCode function tries to create them. The FTP user name to is limited to 30 characters.

The file attachment architecture is designed for use in the frame template or the iframe template only. It is not supported in a pagelet or an HTML template. When content is rendered in a pagelet or HTML template, the user interaction is managed through the PeopleSoft portal servlet. For the file attachment architecture to work, the browser must communicate directly with the PeopleSoft content servlet, which requires the use of the frame or iframe template.

The one-megabyte transfer chunk size between web server and application server cannot be customized. The web server-to-application server transfer is performed by using Oracle Jolt, which is securely encrypted. Because this transfer is done using the standard Oracle Jolt mechanism, no additional settings to the firewall are required you do not need to open additional ports. The file chunks from the web server are transferred by the application server to a temporary table in the database.

Use the DeleteAttachment function to delete a file from the specified storage location. PeopleCode file attachment functions. The following diagram illustrates the operation of the PeopleCode file attachment functions:. Because these functions abstract the storage of the attachments, you can use any defined storage location. The location to be used is determined by the URL passed as the first parameter to the invoked attachment function.

When the user selects a file for uploading, file size is not checked until after the file is transferred to the web server. The transfer is terminated if the file size exceeds this parameter. After the file is received at the web server, the file is streamed from the web server to the application server in one-megabyte chunks.

With a call to MAddAttachment, the files are streamed from the browser to the web server in bulk but from the web server through to the storage location one file at a time. Moreover, virus scanning cannot currently be performed on files uploaded with MAddAttachment. AddAttachment file transfer process. The following diagram depicts this process of transferring a file with the AddAttachment function:.

PeopleCode provides eight built-in file attachment functions that are organized into three categories: AddAttachment Use the AddAttachment function to upload one file from an end user specified location local storage or cloud storage to a specified storage location.

File extension lists cannot be applied to ad hoc URL strings. The length of the full URL is limited to characters. For database tables and the FTP protocol only, the storage location can be specified as an ad hoc string at run time because these file transfer methods do not require additional URL properties. System and Server Administration contains detailed information on creating and maintaining URL objects. The following are examples of some valid storage location URLs:.

Oracle recommends that you always use URL objects since that approach gives you the flexibility of later changing the storage location of your files without having to modify your PeopleCode or the contents of any file reference tables used.

The FTP password to is limited to 16 characters. If the HTTP repository resides on a PeopleSoft web server, then the psfiletransfer servlet has been provided to manage the file transfers to and from the storage location.

Use the CopyAttachments function to copy all files with file references from one storage location to another. The files to be copied can be limited to those referenced in specific file reference tables.

PeopleCode file attachment functions The following diagram illustrates the operation of the PeopleCode file attachment functions: Understanding the File Attachment Architecture File attachments are supported by using PeopleCode built-in functions that implement the transfer of a file to or from a storage location.
