Specifies the percentage of temporary space that an AMP is allowed to use over and above the per-AMP quota (the global maximum space limit divided by the number of AMPs). This is used for databases and users that are created without a SKEW option, or that are created with SKEW limit specified as DEFAULT for temporary space.

This field should be changed only under the direction of Teradata Support Center personnel.

Changes Take Effect

After the DBS Control record has been written.

Usage Notes

  • For operations involving uniform load distribution across all the AMPs in the system, the default skew limit percentage may be set to lower values.
  • If the system involves long running transactions with high space consumption, you can increase the value of the GlobalSpaceSoftLimitPercent DBS Control field to reduce the chances of transaction aborts due to a lack of available space.
