Media database: Data component

The default block size (blk_size) of the data components of the Media database is 10,560. It can be changed to any multiple of 660.

The required number of blocks (num_blks) for the data components of the Media Database depends on the number of records (num_rcds) that are in the data components of the Media Database.

The required number of blocks is calculated according to the following formula:

num_blks = (num_rcds / x1) + 1

where

• x1 is blk_size / 660
• x2 is the number of volumes at the site
• x3 is the average number of files on each volume
• num_rcds = [(x2 * x3) + x2] * 1.1

The value of num_rcds includes a multiplication by 1.1 on the assumption that 10% of the records in the data component of the Media Database are other records.
