B EPICenter Backup
This appendix describes the following:
●
The EPICenter Alarm Log and Event Log backup files
●
The DBVALID command-line database validation utility
●
The DBBACKUP command-line database backup utility
EPICenter Log Backups
Both the EPICenter Event Log and Alarm Log files are kept in tables in the EPICenter database. These
tables can contain approximately 50,000 and 12,000 entries, respectively.
When the EPICenter server starts, it checks once an hour to determine if either of these logs has reached
its maximum size. When one reaches 115% of its maximum, EPICenter moves the oldest 10% of the
entries to a backup file, and clears those entries from the table.
For Windows, the backup files are created in the directory
< install_dir >/user
, where
< install_dir >
is the root directory of the EPICenter install, by default
c:\Program Files\Extreme
Networks\EPICenter 6.0
. For Solaris, the backup files are created in the directory
/opt/
ExtremeNetworks/EPICenter6.0/user.war
, where
/opt/ExtremeNetworks/EPICenter6.0
is the
< install_dir >
.
●
The Alarm Log is backed up to the file
Alarm_Log.txt
●
The Event Log is backed up to the file
Event_Log.txt
Each primary backup file is in turn backed up to a secondary file when it reaches its maximum size of
approximately 30 MB for
Event_Log.txt
and 6 MB for
Alarm_Log.txt
.
●
Alarm_Log.txt
is backed up to the file
Alarm_Log.old
●
Event_Log.txt
is backed up to the file
Event_Log.old
The primary file is then emptied.
When the primary file becomes full for the second time, the secondary backup file will be overwritten
with the new contents of the primary backup file.
If you want to maintain a complete set of log file backups over time, you should save the
*_Log.txt
and
*_Log.old
files periodically.
Database Utilities
Sybase database validation and backup utilities are shipped with the EPICenter software.
The Validation utility validates all indexes and keys on some or all of the tables in the database. The
Validation utility scans the entire table and looks up each record in every index and key defined in the
