How to change class log level in Hybris without restarting server?

Scenario

Sometimes to debug the production issue, we want to enable log level for certain classes which were not configured in local.properties and we hope we could do it without restarting the Hybris server.

Solution

If your hybris version > v6 you can easily do this by navigating hac/platform/log4j . Here you can add your full class package and the log level you want. 





In the older hybris version, you can do the same using the groovy script.

  • Go to HAC > Console > Scripting language
  • Past the below groovy script
  • change your full class in setLogger method setLogger("de.hybris.platform.jalo.flexiblesearch.FlexibleSearch", "DEBUG");
  • execute the script
import org.apache.logging.log4j.*;
import org.apache.logging.log4j.core.config.*;
import de.hybris.platform.util.logging.log4j2.HybrisLoggerContext;

//Example 
setLogger("de.hybris.platform.jalo.flexiblesearch.FlexibleSearch", "DEBUG");

public String setLogger(String logClass, String logLevel ) {
        final HybrisLoggerContext loggerCtx = (HybrisLoggerContext) LogManager.getContext(false);
        final Configuration loggerCfg = loggerCtx.getConfiguration();
        LoggerConfig loggerConfig = loggerCfg.getLoggers().get(logClass);
        if (loggerConfig == null) {
            // create
            String additivity = "true";
            String includeLocation = "true";
            Property[] properties = null;
            AppenderRef[] refs = [];
            filter = null;
            LoggerConfig createdLoggerConfig = LoggerConfig.createLogger(
                    additivity,
                    Level.getLevel(logLevel),
                    logClass,
                    includeLocation,
                    refs,
                    properties,
                    loggerCfg,
                    filter
            );

            loggerCfg.addLogger(logClass, createdLoggerConfig);
        } else {            

    loggerCfg.getLoggers().get(logClass).setLevel(Level.getLevel(logLevel));
        }
        loggerCtx.updateLoggers();
    }
You can see your class will be added to logging list (HAC > Platform > Loggin). Now enjoy debugging!! hope this helps you.

How to remove or update all data records in Hybris?

Open HAC (/hac) Go to console > ImpEx Import Run the below Impex (Change MyItemType with the ItemType for which you want to remove the data) $targetType=MyItemType REMOVE $targetType[batchmode=true];itemtype(code)[unique=true] ;$targetType Scenario 2: Sometimes, you want to remove selected data based on some condition or probably want to run complex SQL query. Then we wish if we could do it by writing SQL query, as many of developers are aware of syntax and its resources are easily available. Solution: Yes, you can do it in Hybris HAC also. Only thing is you should know the appropriate table and attribute/fields names in DB. If you don't, you can always run the select flexible search query and can see generated SQL query. Open HAC (/hac) Go to console > FlexibleSearch Se
