The interval in seconds to scan for reusable before-image clusters before napping.

Use Before-image Scan Time (-biscantime) to tune the process that checks for committed transactions and reusable BI clusters.

For tuning recommendations, see Tune OpenEdge database servers in Optimize OpenEdge Performance.

You can change the scan duration with PROMON or through the _DbParams VST. To turn off the scans, set the -biscantime parameter value to 0.

You can use this parameter to support continuous operation of the database.

For more information, see Change database parameters while the database is running in Optimize the OpenEdge Database for Continuous Operation.
