Customizing the DecisioNet System D-27
Unattended EPL Backup
This feature can be implemented to automatically backup the EPL file
and the EPL Table to its pre-EPL file format at a specified interval. To
accomplish this, an AT job must be set up on a Windows NT system
and a CRON job must be set up on a UNIX system. Refer to your
Windows NT or UNIX system documentation for information about
setting up AT and CRON jobs. This backup can be performed
manually on a DecisioNet Windows NT system from either the EPL
Applications Programs group or from a DOS prompt. On a DecisioNet
UNIX system EPL Backup can be run manually from the UNIX
prompt.
There are two files associated with the Unattended EPL Backup feature
that can be customized. One file contains the list of files to be backed
up. A default list of files is included during installation. Refer to
Appendix C to see the default list. The second file is a post script that
executes to move the files from the EPL backup directory to the site-
specific backup location. Backup files are first placed in the
\epl\data\backup\<date> directory on a DecisioNet Windows NT
system and in the /appl/epl/data/backup/<date> directory on a
DecisioNet UNIX system. To prevent loss of data records, these files
should be copied to a removable device or second hard disk which can
be performed by the second configurable file posteplbackup. Whether
you are performing the backup automatically from an AT or CRON
job, or manually as described above, the posteplbackup files should be
modified to identify the removable device.
Starting EPL Backup at a DOS or UNIX Prompt
The utility to start EPL Backup is eplbackup. The only option is the
number of days to save backups in the EPL backup directory. If
existing backups exist, files older than the specified number are
deleted from the backup directory. For example, if eplbackup 3 is
used and the date is February 7, 1998; then all backup files before
February 4, 1998 are deleted.
