Data transfer methods

Before you begin to transfer files, you must choose the appropriate file transfer type.

You can use the default type, ASCII, or specify a different type. ASCII is the Internet standard for character encoding. EBCDIC is the standard for iSeries™. Select the appropriate type according to the following description:

• Use ASCII for transfers of files that only contain text ("text-only" files).
• Use EBCDIC to transfer EBCDIC data between systems that both support EBCDIC. This will avoid the need to convert data between EBCDIC and ASCII on both systems.
• Use BINARY for transfers of non-text files, such as binary numeric data, graphics files, and iSeries save files.

After you have chosen a file transfer format, you are ready to Transfer a file with FTP.

• Transfer files that contain packed decimal data between iSeries servers
  Using File Transfer Protocol (FTP), you cannot convert special numeric formats like packed decimal or zoned decimal.
• Transfer *SAVF files
  Because *SAVF files must be sent as images, you must issue FTP BINARY subcommand before transferring these types of files.
• Transfer QDLS documents
  When a QDLS document is transferred, the QDLS directory entry attribute that indicates the type of document is defaulted to the document type PCFILE on the receiving iSeries server for all document types except revisable-form text (RFT) documents.
• Transfer root, QOpenSys, QLANSrv, QDLS, and QOPT files
  You must use stream mode (MODE S) and file structure (STRUCT F) when transferring files in the root, QOpenSys, QLANSrv, QDLS, and QOPT file systems.
• Transfer files using QfileSvr.400
  The QFileSvr.400 file system provides access to other file systems on remote iSeries servers.
• Transfer QSYS.LIB files
  This topic discusses the FTP operations for the QSYS.LIB file system.
• File pre-creation considerations
  It is strongly recommended that you pre-create any files that are to be transferred into the iSeries QSYS.LIB file system. This is the best method of ensuring that your data is transferred reliably and effectively with optimal performance and integrity.
• Coded Character Set Identifier conversions
  iSeries uses Coded Character Set Identifier (CCSID) information to interpret the input data and provide the output data in the proper format for display.
