Administration Guide : Database synchronization : Scheduled syncs

Scheduled syncs
Xinet can be told to periodically synchronize all database-enabled volumes to the file system. This is done in the Database, Admin, Quick Sync page.
By default, a periodic sync is set to run once a week on Sundays at midnight. You can change that to be any time you like, running it as often as once a day. The times are recorded in the following file:
Unix: /var/adm/webnative/dblogd.conf
Windows: C:\Program Files\Xinet\WebNative\Admin\dblogd.conf
Periodic syncs are managed by the dblogd(8) process. At the time of the sync, the running dblogd(8) process spawns a child. The child dblogd(8) manages the synchronization actions. For every event that requires an update to the database, the child dblogd(8) spawns its own child. The “grandchild” process dies when the event has been given to mysqld. The “child” process dies when the sync is complete. While a periodic sync is happening, you will see a parent dblogd(8), a child dblogd(8), and possibly a grandchild dblogd(8) with a very short life span.
A periodic sync affects all enabled volumes; you can’t specify volumes you don’t want synced.
Periodic syncs are similar to running a syncvoltodb path_to_volume; for example,. a sync with no flags. For more details on the -delnorm flag, see "Syncs: to -delnorm or not to -delnorm” on page 638. In effect, this means that the sync done periodically is less thorough (but much quicker) than a sync done with the -delnorm option.
Every periodic sync will cause the venture.log file to be moved to venture.log.old. A new venture.log is not created immediately, but rather when the need to log something arises. In other words, you may not see a venture.log file after a periodic sync.
The main purpose of running a periodic sync is to catch minor discrepancies between the file system and the database that were not caught by dblogd(8) or listdir. Note that periodic syncs will not catch every type of discrepancy. In those cases, a sync using one of the -delnorm options is more appropriate.
