If you are looking for how to set BIX logging to DEBUG or ALERT level,

ExtractImpl is the main class that you want to turn on debug for when running BIX.

com.pega.pegarules.data.internal.access.ExtractImpl

Turning on debug for these classes can also be useful.

com.pega.pegarules.data.internal.access.ExtractParameters

com.pega.pegarules.data.internal.access.DatabaseUtilsCommonImpl

Incase logging level settings needed to be changed while running BIX from commandline, Navigate to config folder of BIX (PegaDistributionImage->AdditionalProducts->BIX->config).

Open prlogging.xml/prlog4j.xml.

Following appenders can be found:

<Logger name="com.pega.pegarules.data.internal.access.ExtractImpl" additivity="false" level="info">

          <AppenderRef ref="BIX"/>

 </Logger>

<Logger name="com.pega.pegarules.data.internal.access.ExtractParameters" additivity="false" level="info">

          <AppenderRef ref="BIX"/>

</Logger>

<Logger name="com.pega.pegarules.data.internal.access.DatabaseUtilsCommonImpl" additivity="false" level="info">

          <AppenderRef ref="BIX"/>

</Logger>

Change the "level" to "DEBUG" or "ALERT" as you require in each of the above appenders.

This is to log BIX entries in DEBUG and ALERT modes.

Please let me know incase you are looking for something else.
