What happens when acceleration fails

If a failure occurs while a query is running on an accelerator server, Db2 runs the query under certain conditions.

Db2 runs the query in the following cases:

• The setting for the QUERY_ACCELERATION subsystem parameter is 2 (ENABLE_WITH_FAILBACK), and the CURRENT QUERY ACCELERATION special register is not set.
• The setting for CURRENT QUERY ACCELERATION is ENABLE WITH FAILBACK.
