takes effect
After you edit your onconfig file and restart the database server.
When you reset the value dynamically in your onconfig file by running the onspaces -f command.
After you run the SQL administration API task() or admin() function with the set dataskip argument.

Usage

Whenever the database server skips over a dbspace during query processing, a warning is returned.

Enable the DATASKIP configuration parameter with caution because the results are always suspect. Only enable the parameter in the following situations:
  • You can accept the compromised integrity of transactions.
  • You can determine that the integrity of the transaction is not compromised, which can be difficult and time consuming.
