Syntax documentation Medium Locate the document in the library structure

The Loader uses a medium to physically store the data stream outside the database instance.

If you use the Loader to transform data, the data source and data target are database instances and media, depending on the type of transformation. You can specify the type of the medium in import and export commands for the data stream in the syntax element mediumtype_spec.

Syntax

<mediumtype_spec> ::= FILE | PIPE | TAPE [<ebid_spec>]

FILE

The medium for the data stream is the file system.

PIPE

The medium for the data stream is a pipe.

TAPE

(Relevant for exporting data only): The medium for the data stream is a tape that is addressed by a third-party backup tool.

TAPE <ebid_spec>

(Relevant for importing data only): The medium for the data stream is a tape that is addressed by a third-party backup tool.

<ebid_spec>

EBID '<valEBID>'

You have to specify the external backup ID valEBID of the data stream to be loaded.

Explanation

You can use the syntax rule mediumtype_spec to assign a medium to the data stream. The Loader differentiates between the media types specified in mediumtype_spec. If you do not specify a media type, the Loader uses the file system (FILE) as the medium for the data stream.

Using Backup Tools from Other Providers

Media type TAPE is supported for exporting/importing the entire database and/or the entire database catalog. In this case a backup tool from other providers is used for exporting/importing.

You must perform the following steps when you use backup tools from other providers:

...

       1.      Connecting Backup Tools from Other Providers

       2.      Specify the backup tool
To do so, use the Loader command SET BACKUPTOOL.

After you have finished exporting data with a backup tool from another provider the external backup ID valEBID is written to the log file and the transformation table of the Loader (see Log Functions). If necessary, you must use this log information to determine the external backup ID.

When you import data using backup tools from other providers, the external backup ID must be specified after the keyword TAPE.
