¹ Activity and status of ABL temp-tables is available in this virtual system table. The statistics gathered allow you to monitor the operation and performance of deployed client temp-tables. Specify the range of temp-tables to track with the -ttbasetable and -tttablerangesize startup parameters. Specify temp table indexes with -ttbaseindex and -ttindexrangesize startup parameters. For more information monitoring and debugging temp tables with VSTs, see OpenEdge Development: Debugging and Troubleshooting.
