Today i upgrade one TDI 7.1.1 JVM  to the latest fix from IBM.

The setup was easy, just unzip the file and copy to jvm directory.

When i launch an assembly line using delta.  The log file show the following error:

CTGDKE039E Error occurred when creating IBM Tivoli Directory Integrator Property store. Property store: System-Properties Exception: java.sql.SQLNonTransientConnectionException: java.net.ConnectException : Error connecting to server localhost on port 1527 with message Connection refused: connect.

The derby database was not starting, and in derby.log i found:

2016-07-06 20:44:01.917 GMT : Access denied (java.net.SocketPermission localhost:1527 listen,resolve)
java.security.AccessControlException: Access denied (java.net.SocketPermission localhost:1527 listen,resolve)

I try everything on  http://www-01.ibm.com/support/docview.wss?uid=swg21450475

The problem was related to permission. The text bellow is from https://db.apache.org/derby/releases/release-10.10.2.0.html

After upgrading to a JVM with these changes, while attempting to boot, the network server may fail and raise the following error:

access denied (“java.net.SocketPermission” “localhost:1527” “listen,resolve”) java.security.AccessControlException: access denied (“java.net.SocketPermission” “localhost:1527” “listen,resolve”)

To workaround this problem, you must bring up the network server with a security policy which includes the now required missing permission. Instead of booting the network server as:

java org.apache.derby.drda.NetworkServerControl start

boot the network server as follows:

java -Djava.security.manager -Djava.security.policy=${yourPolicyFile} org.apache.derby.drda.NetworkServerControl start

where ${yourPolicyFile} is a file containing a customized version of the policy file described in the Derby Admin Guide section titled Basic Network Server security policy. You must customize that generic policy file to fit your application. In addition, you must add the following permission to the permissions block granted to the ${derby.install.url}derbynet.jar codebase:

permission java.net.SocketPermission “localhost:${port}”, “listen”;

where ${port} should be replaced by the port number where the network server listens for incoming connection requests. By default, that is port 1527.

Solving the problem

I add  permission java.net.SocketPermission “localhost:1024-“, “listen”; to the grant session of the java.policy file and restart TDI

WebSphere Liberty was certified to Java EE 7 Web Profile and Full Platform in June, 2015.
  • Ease of connecting existing on-premises applications with Bluemix® services, which include IBM Watson™ cognitive for optimal business outcomes.
  • Enhanced support for creating, documenting, and discovering APIs, and also integrating with API platforms, such as IBM API Connect™.
  • Significant improvements in software delivery lifecycle times through seamless integration into DevOps workflows. This enables continuous delivery and removes cross-team dependencies for deployment.
  • Accelerated pace of development and deployment by taking advantage of container technology that includes IBM® Container Services and Docker container with support for Docker Data Center. This enables seamless deployment of WebSphere applications to best meet business needs.
  • Increased flexibility to deploy WebSphere Application Server workloads with speed and agility on Pivotal Cloud Foundry, Amazon Web Services, Microsoft™ Azure, and Openshift, in addition to IBM Bluemix.
  • New WebSphere Application Server on Bluemix, single-tenant offering, which provides an option for deploying WebSphere Application Server applications on an isolated, single-tenant hardware.
  • New option to enable VMware customers to quickly provision new or scale existing workloads to the IBM Cloud. This enables clients who start locally and scale globally with cloud capabilities to scale more easily and also comply with data residency and other regulatory mandates.
  • Updated WebSphere Extreme Scale that provides ease-of-use enhancements for caching to help improve response times for the most demanding applications and dramatically speed configurations.
  • Use of Liberty App Accelerator to provide a quick start development of Java microservices. Spring Boot, Watson™ services, and other technologies can be used with Liberty App Accelerator to easily deploy projects to Bluemix.
  • Best practices for creating new Java microservices by using Game On!, an exemplar application, which helps explore microservices concepts.

WebSphere Application Server V9.0 continues to offer the leading, open-standards-based application foundation for traditional workloads and also modern applications that tend to be delivered as services. It enables accelerated delivery of innovative applications with unmatched operational efficiency, reliability, administration, security, and control.

The Liberty profile has support for java 8 for some time. If you want java 8 on WebSphere 8.5.5 full profile you must apply the fix pack 9 first.

Installing the optional Java 7.0 or Java 7.1 or 8 does not imply that profiles can take advantage of this new version of Java.  The managesdk command has to be used to switch Java or the WAS Admin Console. wsadmin can also be used.

Instructions on how to use the managesdk can be read on this IBM TN

See the SDK version for each WAS version on this link

“There are a number of aspects to consider when choosing between the traditional WebSphere Application Server (WAS full profile, or WAS Classic) and WAS Liberty for deployment. If you
have a hard requirement which is only available on one or the other (such as a particular API) then the choice is easy, but as the Liberty function has grown, it has become more common to
need to weigh the pros and cons of each more closely; to consider topology choices, operational capabilities and security options. Over one hundred and fifty IBM products have shipped with
Liberty as their internal application server and an ever-growing number of IBM SaaS offerings, such as BPM Workflow and Watson Analytics, are running on Liberty.”

Setup SSO with Windows Desktop is not so hard. But when things is not well documented you can get a big headake.  A customer ask to implement this SSO. The environment was a WebSphere Portal V.8.0 cluster and the user repository was AD 2012.

I setup the system following several documents from IBM and other blogs.  The SSO just not work.

Searching a log for one  solution i found the following:

DES Encryption and Kerberos Authentication:
Starting with Windows Server 2008 R2, domain controllers (and domain members) will no longer allow DES encryption for Kerberos tickets. DES encryption was cracked last millennium, so it’s time to move on to better encryption mechanisms like AES.

http://blogs.technet.com/b/askpfeplat/archive/2013/06/03/upgrade-active-directory-to-windows-server-2012-phase-1-assessment.aspx

The solution was simple:

Before AD 2008  the keytab generation was:

ktpass –out appserver1.keytab –princ HTTP/[email protected] –mapuser wastest –pass password -ptype KRB5_NT_PRINCIPAL

For AD 2012 the keytab command line must include the encryption type other than DES and one supported by WebSphere V8.0.x.

I use the following:

ktpass –out appserver1.keytab –princ HTTP/[email protected] –mapuser wastest –pass password -ptype KRB5_NT_PRINCIPAL -crypto RC4-HMAC-NT

The RC4-HMAC-NT did the trick.

This document show the step by step i follow.

WebSphere WebSphere Portal

Several versions of WebSphere Portar are vulnerable.

BM WebSphere Portal could allow a remote attacker to obtain sensitive information, caused by the failure to restrict access to resources located within web applications. An attacker could exploit this vulnerability to obtain configuration data and other sensitive information.

Novamente estou fazendo um export e import de um Portal. Desta vez é um pouco diferente pois estamos exportando um portal de produção e importando em um portal de desenvolvimento. Existem algumas possibilidades para executar a tarefa. Uma delas é executar a tarefa empty-portal no ambiente de desenvolvimento e fazer um import full do portal de produção. Esta foi a primeira tentativa, mas um erro de chaves duplicadas no banco de dados do portal impediu que a importação fosse realizada com sucesso, mesmo executando a task cleanup.
A solução foi utilizar o Release Builder e importando somente a diferença entre um portal e outro. Isto somente foi possível porquê a primeira versão do portal foi criada exportando o Desenvolvimento e importando na máquina de Produção via XMLAccess.
Instruções de como utilizar o Release Builder pode ser encontrada no Infocenter.
