SSL / TLS settings for SAP NetWeawer

Tarafından yazılmıştır

A lot of SAP product such as NetWeaver using sapcrypto / commoncrypto library (sapcryptolib.dll or sapcryptolib.so) for SSL / TLS and encryption.

SSL / TLS client configuration.

ssl/client_ciphersuites = 150:PFS:HIGH::EC_P256:EC_HIGH

SSL / TLS server configuration. 

ssl/ciphersuites = 135:PFS:HIGH::EC_P256:EC_HIGH

You need at least 8.4.40 sapcrpytolib for SNI (Server Name Indication) support. Before SNI protocol client request certificate with domain IP instead of domain name. SNI used for hosting multiple site on same port with encryption.

ssl/client_sni_enabled = TRUE

We need updated kernel for using this parameter, details are in this note.

You can also set this option with OS environment variable.

SAPSSL_CLIENT_SNI_ENABLED = TRUE

Minimum sapcryptolib versions for protocols.

ProtocolVersion
TLS 1.05.5.5 PL 28
TLS 1.28.4.31
SNI8.4.40

My hybris development environment test
		
Tarafından yazılmıştır 
	

	

		
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

DB connection for DDL in groovy
		
Tarafından yazılmıştır 
	

	

		
DANGER!!!


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!!!


[code]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();

dataSource.setDriverClassName(config.getString(“db.driver”));

dataSource.setUrl(config.getString(“db.url”));

dataSource.setUsername(config.getString(“db.username”));

dataSource.setPassword(config.getString(“db.password”));

JdbcTemplate jdbc = new JdbcTemplate(dataSource)

jdbc.execute(“ALTER TABLE MYTABLE ALTER (P_MYFIELD BIGINT)”);[/code]



  
  

			

	


							


	

	
Using separate file for different class logging
		
Tarafından yazılmıştır 
	

	

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


[code]log4j2.appender.FlexlogAppender.type=RollingFile log4j2.appender.FlexlogAppender.name=FlexlogAppender

log4j2.appender.FlexlogAppender.fileName=${HYBRIS_LOG_DIR}/Flexlog.log

log4j2.appender.FlexlogAppender.filePattern=${HYBRIS_LOG_DIR}/Flexlog.log-%d{yyyy-MM-dd}.log

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[/code]
