DB connection for DDL in groovy


In hybris hac, you cannot run DDL (data definition language) commands. You need unprotected connection to db. You can use below example. DDL commands are dangerous!!!

import java.util.List;
import javax.sql.DataSource;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DriverManagerDataSource;

def config = spring.getBean("configurationService").getConfiguration();

DriverManagerDataSource dataSource = new DriverManagerDataSource();
JdbcTemplate jdbc = new JdbcTemplate(dataSource)

Using separate file for different class logging

Below example logging flexiblesearch class to separate file with time based trigger policy. Also we can add rollover strategy for removing old files.

log4j2.appender.FlexlogAppender.type=RollingFile log4j2.appender.FlexlogAppender.name=FlexlogAppender
log4j2.appender.FlexlogAppender.ImmediateFlush=true log4j2.appender.FlexlogAppender.layout.type=PatternLayout
log4j2.appender.FlexlogAppender.layout.pattern=%m%n log4j2.appender.FlexlogAppender.policies.type = Policies
log4j2.appender.FlexlogAppender.policies.time.type = TimeBasedTriggeringPolicy log4j2.appender.FlexlogAppender.policies.time.interval = 1000000
log4j2.appender.FlexlogAppender.policies.time.modulate = true log4j2.logger.flexible.name = de.hybris.platform.jalo.flexiblesearch
log4j2.logger.flexible.level = DEBUG log4j2.logger.flexible.appenderRef.stdout.ref = FlexlogAppender log4j2.logger.flexible.additivity = false

Installing SAP Netware ABAP 7.51 SP02 on CentOS 7 Minimal

You can find great documentation for installing SAP Netware ABAP 7.51 SP02 at Julie blog post. I didn’t use shared OS because of huge disk/ram usage.

SAP Netware using uuidd library for generating GUID, install it.

yum install uuidd
Install vmware tools and shared folder

Changing item attribute type in hybris

Some times you need attribute type change in hybris. Hybris as own ORM and it is not support updating attribute type. If you change attribute type you will get error like this:

de.hybris.platform.servicelayer.exceptions.ModelSavingException: <########## NewPropError ##########> value type mismatch in unlocalized property ‘myproperty’ of ‘myitem’ : expected ‘class java.lang.Integer’ but got ‘class java.lang.Long’

If you don’t want to adding new field than migrating data and removing old, you can use below procedure.

  • Change column type in DB. You cannot do this on hac because DDL disabled.
  • Update system in hac (Platform -> Update without Create essential data option).

Mount shared folder in VM

You can use below command for mount shared folder to VM guest. You need install vmware tools before use this.

/usr/bin/vmhgfs-fuse .host:/ /mnt/hgfs -o subtype=vmhgfs-fuse,allow_other
