UNLOAD Control Statement

The UNLOAD control statement allows for unloading the SYSOUT data for SYSOUT groups archived to secondary disk storage.

Syntax:

UNLOAD SECOND|NOSECOND

where:

SECOND: Does not unload the SYSOUT data for SYSOUT archived to secondary disk storage.
NO SECOND: Does not unload the SYSOUT data for SYSOUT archived to secondary disk storage.

The SECOND/NOSECOND parameter has a default value of NOSECOND. Specifying SECOND can substantially increase the time required to perform the UNLOAD function.

Whether or not you specify SECOND when unloading, the LOAD function never reloads the SYSOUT data for SYSOUT groups archived to secondary disk storage. The LOAD function merely transfers ownership of the secondary disk storage that is already archived.

You must specify SECOND when unloading the databases if you are going to use the MERGE function, because the MERGE function always reloads the SYSOUT data, either to primary or secondary disk.
