This is my workaround.
I call this method after the Teradata JDBC driver is loaded.
static void resetLoggingConfiguration()
{
try
{
LogManager.resetConfiguration();
String strConfig = System.getProperty("log4j.configuration");
URL configFile = new java.net.URL(strConfig);
DOMConfigurator.configure(configFile);
Logger rootLogger = LogManager.getRootLogger();
rootLogger.setLevel(Level.ALL);
}
catch (Exception ex)
{
ex.printStackTrace();
}
finally
{
log.info("resetLoggingConfiguration() called");
}
