Customizing Domain Wide Server Parameters

To customize domain wide server parameters in WebLogic Server, configure setUserOverrides.cmd (Windows) or setUserOverrides.sh (UNIX) libraries by specifying the required Java command line options and environment variables to it.

Every domain includes dynamically generated domain and server startup scripts, such as setDomainEnv. Oracle recommends that you do not modify these startup scripts, as any changes you make to them will be overwritten during subsequent domain upgrade operations.

To enable you to customize server startup parameters that apply to the servers in a domain, there are two scripts that you can provide: setUserOverrides.cmd and setUserOverridesLate.cmd (Windows) or setUserOverrides.sh and setUserOverridesLate.sh (UNIX). The setUserOverrides script will be executed early in the setDomainEnv script, before any domain extension template properties have been set. The setUserOverridesLate script will be executed later after the domain extension template properties have been set. These scripts can be configured to, for example, add custom libraries to the WebLogic Server classpath, specify additional java command line options for running the servers, or specify additional environment variables. Any customizations you add to these files are preserved during domain upgrade operations and are carried over to remote servers when using the pack and unpack commands.

To assure your customizations effectively override all product defaults, add your customizations to the setUserOverridesLate script, otherwise your customizations may be overridden by product extensions when using setUserOverrides.

Log format pattern - set via Weblogic console or WLST

Disable Spring DEBUG in log4j2 logs on Weblogic

HOWTO 

•  https://www.baeldung.com/spring-boot-disable-console-logging
•  https://stackoverflow.com/questions/43872823/spring-boot-cannot-turn-off-logging
  

 

There is dump of all environment variables in Weblogic log due to Spring initialization

2022-05-12 14:13:43,673;DEBUG;com.bea.core.repackaged.springframework.core.env.AbstractEnvironment;<init>();125;Initialized StandardEnvironment with PropertySources

 

To remove it add logger for com.bea.core.repackaged.springframework into log4j.xml file

    <logger name="com.bea.core.repackaged.springframework" additivity="false">
        <level value="error" />
        <appender-ref ref="some-appender"/>
    </logger>
