values
0 = Enable logical logging on temporary table operations

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 onmode -wf command.
When you reset the value in memory by running the onmode -wm command.

Usage

This parameter can improve performance in application programs because it prevents HCL OneDB™ from transferring temporary tables over the network. The setting can be updated dynamically with the onmode -wf utility.

If you enable this setting, be aware that because no data is logged when using temporary tables, rolling back a transaction on a temporary table will no longer undo the work in the temporary table.

For HDR, RSS, and SDS secondary servers in a high-availability cluster, logical logging on temporary tables should always be disabled by setting the TEMPTAB_NOLOG configuration parameter to 1.
