This section describes how to handle extraction information queue files and import information queue files whose maximum size is at least 2 GB (large files). In this section, the extraction information queue files and import information queue files are referred to generically as queue files.

In the Windows edition

To use large files in the Windows edition, specify 2097152 (2 GB) or a greater value in the queuesize operands in both the extraction environment definition and the import environment definition.

In the UNIX edition

To use large files in the UNIX edition, specify 2097152 (2 GB) or a greater value in the queuesize operands in both the extraction environment definition and the import environment definition, and specify appropriate OS settings as well as the maximum size of the Datareplicator file system area. For details, see 6.11.1 Preparations for handling large files (UNIX edition only).

Note

If the size of an existing queue file has been changed, Datareplicator must be initialized. Therefore, before you change the file size, verify that replication has been completed.
