About this task

If you encounter lock issue of the taskexecutionhistory table in the database, follow these steps to resolve it.

Procedure

  1. Open the configuration.properties file to edit it.
  2. Set lockTimeout for connection pool by URL, for example:
     jdbc:sqlserver://localhost:1433/tac801;lockTimeout=1800
