Specifies the type of logging that is to be used. The default implementation for the Oracle GoldenGate for Big Data is the jdk option. This is the built-in Java logging called java.util.logging (JUL). The other logging options are log4j or logback.

For example, to set the type of logging to log4j:

gg.log=log4j 

The recommended setting is log4j. The log file is created in the dirrpt subdirectory of the installation. The default log file name includes the group name of the associated Extract and the file extension is .log.

<process name>_<log level>_log4j.log

Therefore if the Oracle GoldenGate Replicat process is called javaue, and the gg.log.level is set to debug, the resulting log file name will be:

javaue_debug_log4j.log
