The data sets comprising the database have the following attributes:
DSORG=DA or PS RECFM=F SPACE=(CYL,,,CONTIG)
Although the data sets are marked as movable, they can only be moved to a volume of the same device type. Each data set must also occupy one contiguous extent, occupy the same number of cylinders, and be allocated on a cylinder extent boundary.
A unique block size can be assigned for the database index file and data file data sets using the ADDDS statement of the SARDBASE utility. The default block size for the database index file data sets is 8906, and the default block size for the database data file data sets is 3768.
For data sets that are more than 4,369 cylinders, the data sets are allocated as physical sequential data sets (DSORG=PS) due to IBM restrictions.
The data sets are assigned names in the following format:
Syntax
index.SARDBASE.tnnnnnnn
Where
Specifies the high-level name of the database.
The index comprises one or more qualifiers separated by periods. The maximum length of the index is 17 characters.
Specifies the type of data set as either I for index file data set or D for data file data set
Specifies the relative sequence number of the data set within the database.
