DESCRIPTION
The omnidbutil command is used for Data Protector internal database (IDB)
maintenance tasks. These tasks involve:
OPERATIONS ON DETAIL CATALOG BINARY FILES (DCBF)
The Detail Catalog (DC) is composed of three parts: 1) Catalog Database (CDB)
tablespace containing pathnames of backed up files together with client system
names. 2) The Detail Catalog Binary Files (DCBF) part, which stores file version
information (file size, modification time, attributes/protection, exact position on a
medium (block level) and so on). 3) DCBF directories: registered directories that
contain DCBF. A DCBF directory is allocated when creating new DCBF using one of
three possible allocation algorithms, specified in the Data Protector global options
file by the DCDirAllocation option. The Data Protector global options file resides
on the Cell Manager in the directory
Data_Protector_program_data\Config\Server\options (Windows Server
2008), Data_Protector_home\Config\Server\options (other Windows
systems) or/etc/opt/omni/server/options (UNIX systems).
Operations on DCBF include: 1) Registering, removing and updating DCBF directories.
2) Locating DCBF across DCBF directories if they had been moved manually. 3)
Removing invalid references to DCBF. Invalid references can occur after the DB
recovery during which the replay of IDB transaction logs is executed. In this case
CDB is newer than DCBF.
The omnidbutil options used for operations on DC are: -list_dcdirs,
-add_dcdir, -modify_dcdir, -remove_dcdir, -remap_dcdir and
-fixmpos.
