MapDB
You need write access to the SysDB to create or alter MapDB, to specify the product
license, or alter global configuration parameters. You need read access to execute
some commands, especially to start the monitor process.
When AutoSYNC needs to access the SysDB, it looks first for SysDB tables in
$SYSTEM.ESCSYSDB. If the tables do not exist, it then searches all disks for a
SysDB in the ESCSYSDB subvolume. If there is more than one SysDB, the command
interpreter terminates with an error.
MapDB
The MapDB subvolume contains configuration parameters for syncusers and their
scheduled synchronizations, in addition to a set of files used by AutoSYNC to process
synchronizations.

REGISTRY: a SQL table where local configuration parameters are stored. Local
parameters are analogous to global parameters stored in the SysDB REGISTRY
table, but they apply only to a specific MapDB/monitor pair.

SYNCUSER: a SQL table where each syncuser configuration information is
stored.

SFggguuu: SQL tables, one per syncuser, that contains the configuration of
syncfilesets owned by the syncuser.

SLggguuu: Enscribe entry-sequenced files, one per syncuser, that contains the
output log of each syncuser’s scheduled synchronizations.

Temporary files in subvolumes with the MapDB name on all volumes:

On the source, ZBKnnnnn: the input file for BACKUP (or its OSS equivalent),
purged at the completion of the synchronization.

On the destination, ZRSnnnnn: the input file to RESTORE, purged at the
completion of the synchronization.

On the destination, AAnnnnn, ABnnnnn, ACnnnnn: files used for recovery,
purged after the synchronization of a file completes successfully.

On the destination, AAINDEX: a file that contains the mapping of the original
filename to the temporary recovery files AAnnnnn, ABnnnnn, ACnnnnn, etc.
Security and ownership of the MapDB tables determines synchronization privileges of
syncusers. For details see
Authorization and Administration on page 4-1.
The SYNCUSER table is created by using the CREATE MAPDB command. The
SFggguuu and SLggguuu are created when syncuser ggguuu is configured by using
the
ADD SYNCUSER command.
