      lv_pos     TYPE i,
      lv_len     TYPE i.
lv_content = 'dummy string'.
lv_pos = 1.
WHILE lv_pos LE strlen( lv_content ).
  lv_len = 80.
  IF lv_pos + lv_len GT strlen( lv_content ).
    lv_len = strlen( lv_content ) - lv_pos.
  WRITE lv_content+lv_pos(lv_len).
  lv_pos = lv_pos + 80.

If SOAMANAGER not exists

Some old system hasn’t got SOAMANAGER for configuring/creating logical port or service. We can use below t-codes for same operation.


Linux check list

Install tools for operation.

yum install nano wget epel-release


If you update some packages, your config files override with new ones. You can find old files with rpm extension in same directory.

Latest Packages

Some linux distributions update their package with delay. IUS is good option for using latest package. You can get IUS package list here and install them with below command.

Install ius rpm package first:

yum install https://centos7.iuscommunity.org/ius-release.rpm

Use u suffix for Installing package from ius repo. For example use below for installing git 2.x:

yum install git2u


Download rpm package, check this list for other versions.
wget https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-3.noarch.rpm
Install package.
rpm -i pgdg-centos96-9.6-3.noarch.rpm
yum install postgresql96-server postgresql96-contrib
/usr/pgsql-9.6/bin/postgresql96-setup initdb

Create db and user.

su postgres
createuser --interactive
createdb -O myuser mydb

Run psql for setting password to new user.

ALTER USER mydbuser WITH PASSWORD 'mynewpass';


If you need proxy you can use nginx. You need give permission to nginx for accessing http resources.

setsebool httpd_can_network_connect true -P

Check nginx.log with

tail -10f /var/log/nginx/error.log

php & php-fpm

Use IUS for latest release, php72u.

Permissions overwritten after update, check /var/lib/php/fpm permissions.

My hybris development environment test

I am using my company mac pro 2015 for a lot of thing. So I need different environment look like C#, hybris, ABAP, etc. These environment needs service look like db. These service using my ram always. So I am using VM for environment which are not used often. I created VM for new hybris versions for testing (docker cannot pause / resume systems yet). I try some scenarios for my best hybris development environment.

VM: OS version Centos 7, Java 8 u162, MySQL 5.7.21 and hybris version 6.6.

Enviroment Compile time (ant clean all)
Hybris files in host shared with guest vm 21 minutes 9 seconds
Hybris files in guest vm 3 minutes 8 seconds
2 minutes 29 seconds
Hybris files in guest vm and shared with host (without nfs optimization)  5 minutes 44 seconds


Creating history for item

If you want create history for item look like backoffice, you can use below example.

public void updateConsignmentStatus(String userUid, ConsignmentModel consignment, ConsignmentStatus status) {
  Map<string, object=""> originals = new HashMap();
  originals.put(ConsignmentModel.STATUS, consignment.getStatus());


  Map<string, object> news = new HashMap();
  news.put(ConsignmentModel.STATUS, consignment.getStatus());

  final SavedValues savedValues = JaloConnection.getInstance().logItemModification(consignment.getPk(), news, originals, false);

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 groovy example. Attention: 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
