Bulk Import Tool imports documents in bulk into an object store. The documents are usually in the form of TIFF images and are generated by an external process.
The documents are imported as a batch process. The location of the documents to be imported is specified in the transact.dat file. They can be in the same directory as the transact.dat file, in a subdirectory, or in a different location.
The Bulk Import Tool is multi-threaded, so you can
run multiple batches in which each thread processes batches simultaneously.
Threads can be set to three by default or to another value by using
the -CE switch. If you run a single batch of
100,000 items, one thread processes all of the items in that batch.
The other two threads sit idle while the batch is processed.
The location of the transact.dat file is specified in the batchname.eob file. The batchname.eob file is in the working directory. The transact.dat file is used to tell the Bulk Import Tool how to process the batches of documents. The transact.dat file provides information that describes the makeup of each document. The transact.dat file also provides a class code. This code associates the document with a document class, property values to assign to the document, and content description paths, such as the location of the document content. All of the information is used in Bulk Import Tool operations and can contain definitions to different document classes in the same batchname file.
