ADD SYNCFILESET
if the global SYNCRECOVER parameter is set to OFF or if NO
RECOVERY was specified when the file set was created or altered.
OWNER user-id | user-name
the owner of the destination file set.
If OWNER is omitted, the owner of the source file is retained.
PRI[ORITY] priority
the process priority at which the ASYSYNC process is to run when processing
this syncfileset.
If the priority exceeds the value of MAXPRIORITY set with the
command, it is overridden by the
syncuser's MAXPRIORITY.
If this option is omitted, the priority of ASYSYNC is set to the priority of the
syncuser.
PURGE
specifies that any file that is in the destination file set but is not in the source
file set will be purged. By default AutoSYNC does not purge any file in the
destination file set.
To exclude files from being purged on the destination, use the
EXCLUDEPURGE option.
Guardian file sets:
If PURGE is specified, the subvolume portion of the source and destination
file sets must be fully qualified (no wild-card characters or "*").
Purging of files occurs on a subvolume by subvolume basis. A destination
file is not purged if it does not exist in a corresponding source subvolume,
unless the SUBVOLPURGE option is also specified.
Extra SQL objects in the destination like tables, views and indexes are
purged. Catalog files are not supported and they are not synchronized or
purged by Autosync.
Note for OSS file sets. AutoSYNC only synchronizes updates that are actually sent
to the disk process. Any updates that are buffered in the application process (such as
performed by the file system or C runtime) are not synchronized until they are
transmitted to the disk process.
Note for OSS file sets. If OWNER is specified and OWNERGROUP is omitted, the
OWNERGROUP of the file set is set to the group of the source file, not the group
specified by OWNER.
Note. Be aware that running ASYSYNC at high priority may impact system
performance as the process is CPU bound.
