Specifying free space for a KSDS (FREESPACE parameter)

To include free space in a CI in a KSDS, use the FREESPACE parameter in the DEFINE CLUSTER command.

Free space for a KSDS cannot be specified using the FRSPC= keyword in the DBD.

You specify free space in the FREESPACE parameter as a percentage. The format of the parameter is FREESPACE(x,y) where:

x: is the percentage of space in a CI left free when the database is loaded or when a CI split occurs after initial load
y: is the percentage of space in a control area (CA) left free when the database is loaded or when a CA split occurs after initial load.

Free space is preserved when a CI or CA is split by coding INSERT=SEQ in the OPTIONS control statement.

If you do not specify the FREESPACE parameter, the default is that no free space is reserved in the KSDS data set when the database is loaded.
