Setting up accelerator groups

Accelerator group support allows you to load multiple accelerators by specifying a single accelerator group name.

About this task

To use accelerator groups in Accelerator Loader, you must identify the accelerator group name to the Db2 system.

Accelerator Loader supports use of an alias for multiple accelerators in one job, one alias per job. For example, you can create an alias_x that refers to both accel_1 and accel_2, then in the job, replace accel_1, accel_2 with alias_x. In a job, you cannot:
  • Specify multiple aliases, for example, alias_x, alias_y
  • Combine an alias with an accelerator, for example, alias_x, accel_3

Procedure

To add an accelerator group name, insert a row into the SYSIBM.LOCATIONS table using the following settings:
Table 1. SYSIBM.LOCATIONS settings for accelerator groups
Column name Description

LINKNAME This column must have the value “DSNACCELERATORALIAS".
DBALIAS The list of accelerators that belong to the group. Separate each accelerator name with a blank space.
