HP B6960-96035 manual IDB architecture, IDB on the Unix Cell Manager

The IDB on the UNIX Cell Manager

IDB location

The IDB on the UNIX Cell Manager is located in the /var/opt/omni/server/db40 directory.

IDB format

The IDB on the HP-UX and Solaris Cell Manager stores all text information in ASCII single- and multi-byte formats.

The ASCII format limits the support of filenames and messages localized to other languages. When backing up files with filenames in a double-byte format, such as UNICODE, the filenames are converted to the ASCII format and may not appear correctly in the Data Protector user interface. However, the files and filenames will be restored correctly.

For more information, see “Internationalization” on page 340.

The IDB in the Manager-of-Managers environment

In the Manager-of-Managers (MoM) environment, you can use the Centralized Media Management Database (CMMDB), which allows you to share devices and media across several cells. For more information on the MoM functionality, see “Enterprise environments” on page 45.

IDB architecture

The IDB consists of the following parts:

•MMDB (Media Management Database)

•CDB (Catalog Database), divided into two parts: filenames and other CDB records

•DCBF (Detail Catalog Binary Files)

•SMBF (Session Messages Binary Files)

•SIBF (Serverless Integrations Binary Files for the NDMP integration)

Each of the IDB parts stores certain specific Data Protector information (records), influences IDB size and growth in different ways, and is located in a separate directory on the Cell Manager. See Figure 56 on page 190.
