Sometimes users are asked to update an IBM Business Process Manager (BPM)/Lombardi configuration file to overwrite default configuration settings. I hope this step-by-step guide will help a new BPM administrator finish his first configuration update quickly before reading many technote and product documentation pages about the related product design.
What configuration files could/should be changed?
Generally speaking, you should not make changes on the default configuration files directly,... [More]
Did you know that some versions of IBM MQ are noit's thw supported with SELinux enabled on Red Hat Enterprise Linux?
Historically the advice for SELinux was always to disable it when using MQ. However, because SELinux is enabled by default in Red Hat Enterprise Linux it was inconvenient for users to disable it. Also, SELinux provides many security benefits so it's better to leave it enabled where possible.
There are some conditions to the SELinux support. The main ones are:
The minimum MQ versions are... [More]
For Web service processing, there are some things that you need to know about between the different versions of Business Process Manager (BPM).
First, if you haven't installed JR41994 on your BPM 7.5.1 environment, then the SOAP response generated with ns1 prefix may be in the wrong format.
JR41994: INCORRECT NAMESPACE WHEN USING COMPLEX DATA TYPE FROM TOOLKIT
This error occurs in the BPM v22.214.171.124 release. This APAR fixes the situation that For Inbound Web Services in BPM 7.5.1, when a complex... [More]
Many of us are familiar with the traditional IBM Installation Manager (IIM) Eclipse-based rich client, IBMIM , that allows one to drive IIM in an environment where a GUI is available.
However, this approach is not always feasible, especially in an environment where one needs to access IIM on a remote server, perhaps one without a GUI console i.e. operating in so-called "headless" mode.
This is often the case with remote UNIX® servers ( AIX, Linux, Solaris etc. ) where one's only point of access is via... [More]
The Java™ JRE will throw an OOM error for more than just a Java heap with no free space. So the single heapdump you have from an outage might not be useful at all and could lead you down the wrong debugging path. It is very important to get a complete set of documentation from an OutOfMemory (OOM) error. A single heapdump is never enough to figure out the general type of OOM you’re dealing with.
(Note that this information is correct for a WebSphere Java process running with an IBM Java JRE, and... [More]
IBM Business Process Manager (BPM) supports powerful, high-performance business process management while providing a simple way to model business processes.

In late 2014, we published Security Bulletin: Vulnerability in SSLv3 affects IBM WebSphere Application Server (CVE-2014-3566) . As detailed in the bulletin, the IBM WebSphere Application Server could allow a remote attacker to obtain sensitive information, caused by a design error when using the SSLv3 protocol. A remote user with the ability to conduct a man-in-the-middle attack could exploit this vulnerability via a POODLE (Padding Oracle On Downgraded Legacy Encryption) attack to... [More]
In most cases, we normally install multiple interim fixes interactively for one time using the GUI wizard mode of Installation Manager. However, for some special cases, users have a need to install interim fixes silently only using imcl command lines. Therefore, this article will introduce two special situations our users encounter when using the command line to install multiple interim fixes.
1. Command Line Used to Install Interim Fixes
imcl install fixID -repositories repositoryLocation... [More]
Many IBM Business Process Manager (BPM) clients have reported that end users did not get expected authorization privileges while operating human service activities in BPD – “You are not authorized to …”
Hopefully this blog can help you resolve this kind of problem by yourself.
You first need to check the BPD design, and ensure the human service activity is actually supposed to be routed to the user.
If the task is assigned to a particular user, it’s easy to determine whether the... [More]
In some circumstances, you believe that a user belongs to the participant group/team/ad-hoc group directly or indirectly, but the membership records in IBM Business Process Manager (BPM) DB tables do not indicate it. Assuming it’s LDAP security provider configured within WebSphere Application Server (WAS) federated repository, which is the most typical client scenario:
Step 1. Check user-group membership on your LDAP server. Ensure the user and security group exist in LDAP server, and the user belongs to the target... [More]

CPSM (CICSPlex System Manager) makes managing your CICS systems much easier. It is also a requirement if you are going to use the CICS Explorer to view and manage multiple CICS regions. But CPSM can be a challenge to setup for the first time.
One of the questions we often get in Level 2 is how to setup a basic CICSPlex that spans multiple LPARs. That task involves setting up a CMAS on each LPAR and connecting them so that they can talk to each other. While there are a number of ways to do that, I will provide sample JCL below... [More]

Since IBM Business Process Manager (BPM) V8.5.5, users can use the command BPMConfig -update to change the context root to a customized value for a deployment environment. The specified context root is used as a prefix to the default BPM context root. As part of this blog, I wanted to provide set of step-by-step instructions for changing the context root from its default value to new value. I will also mention a few points that you should pay attention to when you use the command.
There are different ways you can check if your backup is still running in version 2.0.
You can check the backup progress on dedicated “Backup and Restore” page under System Console -> System. See my earlier post: Did you know you can follow your backup progress on PureApplication System version 2.0?
Another way to check the progress of your backup is by going to System Console > System > Job Queue page and clicking the “Show Details” icon for the backup job.

During installing Products and Fixes with IBM Installation Manager, Installation Manager searches open repositories where Packages and Fixes exist. But how can you verify the applicable packages, updates, and features are in a target repository from the command line?
Installation Manager provides the command line tool, imcl, to manage installation. The imcl command can be found in <IM_ROOT>/eclipse/tools subdirectory.
Where <IM_ROOT> is root directory where IM is installed.
We will introduce how to... [More]
There are times when Ninja like skills are needed for text search and replace. One example is the instance deletion script. For WebSphere Lombardi Edition V7.2 and IBM Business Process Manager (BPM) V7.5, stored procedures are the options. For BPM 8.0.1 and later, you will want to use the BPMProcessInstanceCleanup command . To make a list of numbers quickly available for the deletion script, we can use some fancy search and replace. For this example I am... [More]

Java heap is the area of memory that is used by the Java virtual machine (JVM) for storing Java objects. Optimal Java heap size is application and use dependent. Setting the JVM heap size is directly related to the number of server instances that needs to be started on a specific node and the total RAM available on the machine. The maximum heap should be incremented not to exceed 50% of overall physical memory. The Java heap memory is used by the applications that are deployed and the component running in... [More]
During the course of WebSphere Application Server operation, a JVM may produce important diagnostic information in a variety of files and formats. In this blog entry, we will briefly examine each of these files and their purpose.
A wealth of valuable Java™ virtual machine diagnostic data can be gathered by doing the following tasks:
1) JVM process standard error stream
In WebSphere, JVM writes some errors messages on the standard error... [More]
Oftentimes opening a Service Request (SR) or Problem Record (PMR) is a last resort so wouldn't it be nice if you could learn from the experience of others and lower the number of SRs you have to open? Well, at the IBM Programming Labs we periodically analyze problem records and any trends associated with them. Knowing beforehand what's out there can pay dividends in time and effort.
In December and January we saw a trend where a number clients experienced the symptoms documented in APAR IT03168 . On... [More]
The WebSphere Application Server does not contain code that provides for a secure database connection method other than basic userid/password authentication, which is implemented through an authentication alias. However, this does not mean you cannot configure another authentication method. Most of the WebSphere Application Server datasource configuration, with the exception of pool configuration parameters, are properties that are simply passed to a JDBC driver package.
For example, if I create a new datasource... [More]
