[ERROR] InitialSync cannot use multiple subtask threads to process Oracle source tables for which virtual columns with Tcl scripts are defined.
InitialSync cannot use multiple subtask threads to process data from Oracle source tables for which you defined and mapped virtual columns with Tcl scripts in the configuration. InitialSync will end abnormally.
To prevent this error, use the default value of 0 in the initial.oracle.parallel_sample_percentage runtime parameter. InitialSync then uses a single thread to process all table rows.
