Control of the temporary result writer with DB2^® Multisystem

By default, queries do not use the temporary result writer. Temporary result writer usage, however, can be enabled by using the Change Query Attributes (CHGQRYA) command.

The asynchronous job usage (ASYNCJ) parameter on the CHGQRYA command is used to control the usage of the temporary result writer. The ASYNCJ parameter has the following applicable options:

• *DIST or *ANY allows the temporary result writer jobs to be used for queries involving distributed files.
• *LOCAL or *NONE prevents the temporary result writer from being used for queries of distributed files.
