The following table describes the files that are associated with file duplexing.
Table 3-28 Files associated with duplexing
| File | Purpose |
|---|---|
| Extraction system definition file or import system definition file | Defines the name of the duplexing definition file. |
| Extraction environment definition file or import environment definition file | Defines the name of the logical files that are to be duplexed. |
| Duplexing definition file | Defines the names of the physical files for each file that is to be duplexed. |
| Duplexing control file | Controls file duplexing. Datareplicator creates this file during initialization processing. |
These files specify the name of the duplexing definition file.
To duplex files for the source system, define the file_dupenv operand in the extraction system definition file; to duplex files for the target system, define the file_dupenv operand in the import system definition file. For details about the file_dupenv operand, see 5.2 Extraction system definition and 5.8 Import system definition. If you omit this operand, you cannot use file duplexing.
These files specify the names of the logical files to be duplexed.
To duplex files for the source system, define the names of the logical files in the extraction environment definition file; to duplex files for the target system, define the names of the logical files in the import environment definition file.
This file defines the correspondence between the names of logical and physical files. For details about the definitions, see 5.7 Duplexing definition (source) or 5.12 Duplexing definition (target).
This file controls file duplexing. Datareplicator creates the duplexing control file in the following directories during initialization processing:
| System | Directory | File name |
|---|---|---|
| Source | Source Datareplicator directory at all HiRDB server machines | hde_fileenv.prp |
| Target | Target Datareplicator directory | hds_fileenv.prp |
After initialization of Datareplicator, make a backup copy of the duplexing control file. If an error occurs on this file, you will have to use its backup file to restore the file.
