Configuration migration is the process of upgrading a WebSphere Application Server installation to a newer major release. Migration leverages the existing configuration and applications and migrates them to the newest version environment. This blog provides important tips when you are running Migration Utilities ( Configuration Migration Tool (CMT) or command line (WASPreupgrade/WASPostupgrade)) to migrate WebSphere Application Server from one version to another.
Make sure that the ulimit for open files is not set to the... [More]
You attempt to change the CEI distribution mode of a newly installed or previous version of a monitor model and specify new credentials. As a result, authentication with the remote cell or server fails and results in a failure of the CEI distribution mode change. This situation occurs if the following conditions are met:
Multiple versions of a monitor model are installed.
The CEI target is remote.
The CEI distribution mode of at least one version is not Inactive.
The credentials (user name and/or password) for... [More]
Modeled faults defined in a WSDL file is the way of handling exceptions in web services at run time. The faults help user understand the problem and issue quick resolution. Before IBM Business Process Manager (BPM) V8.5.5, in order to handle the runtime exception threw out by a web service outbound (Web Service Integration), the only choice is to use "Catch All Errors" option in the "Error Intermediate Event" component. The error message cannot be recognized when developing the business process, and... [More]
Shared resource Directory
The shared resources directory is the directory where installation artifacts are located, which can be used by one or more package groups. The Shared Resources Directory acts as a cache of data to local and web repositories. It contains files that can be shared by multiple packages and product installations.
The location of this directory can only be selected the first time you install a package with the IBM Installation Manager (IM). For example,... [More]
Rolling back or uninstalling a fix pack involves moving from a newer release of a fix pack to a previous release of a fix pack.
We always specify the version we want to rollback to (not the currently installed). I will provide details on this rollback command and a sample usage scenario for you.
./imcl rollback offering_ID_offering_version -installationDirectory installation_directory -acceptLicense -sP
The offering_ID is the... [More]
Continuing on my voyage of discovery with IBM UrbanCode Deploy (UCD), I was having all sorts of fun and games adding a new agent to a "clean" installation of Red Hat Enterprise Linux 6.6.
I chose to add the agent via Resources > Agents > Add New Agent , manually entering details such as hostname, SSH port, user ID and password:
Validating the Agent Installation Properties:
Note that I'd... [More]
Starting with IBM WebSphere Application Server (WAS) v220.127.116.11, you can install Java 7.0 as an optional feature. WAS v18.104.22.168 comes with Java 6 as the default Java SDK. Java 7.0 can be added at any point in time to the installation, thereby adding the Java 7.0 SDK selection to the possible choices of Java SDKs that can be used. For completeness:
Java 7.0 was shipped as an optional feature that can be installed with WAS v22.214.171.124
Java 7.1 is shipped with WAS v126.96.36.199 (in a full... [More]
So I have spent quite literally hours over the past two days working ^H^H^H^H^H^H^H playing with this.
I've got UrbanCode Deploy (UCD) 6.1.0 installed on my VM (running Red Hat Enterprise Linux 6.4) and all is working nicely. However, I was trying, and frequently failing, to get UCD to inspect a WebSphere Application Server (WAS) 188.8.131.52 environment using the Configure using WebSphere Topology Discovery workflow: -
I'd already installed the ... [More]

With IBM Business Process Manager, when big shared business objects are used by long living processes and are saved frequently, then the database tables (BPM_SHARED_OBJECT_INSTANCE and BPM_SHARED_OBJECT_VALUE) for persisting these changes may grow quite large.
Take a look at the conditions that are introduced in the Database can get huge when frequent changes are done for big shared objects document first. In addition to the referenced document, here are... [More]
Upon investigation of a WebSphere Application Server performance issue, you may find that the poor performance correlates with long classloader unload times. To check if this is indeed a problem, enable verbose GC and note the times of poor performance. Then correlate the times of poor performance to the time stamps in the verbose GC data:
Example of long class unload time as seen in the verbose GC output (default log is the native_stderr.log in WebSphere):
This time around, I have a requirement to deploy IBM HTTP Server (IHS) and the WebSphere Plugin to route traffic to WebSphere Application Server (WAS). So far, so good. However, the difference is that, this time, I'm NOT leveraging the power of WAS Network Deployment ( WAS ND ). There are no clusters here. Equally, the two instances of WAS are completely self-contained. For my proof of concept, I've got a single set of WAS binaries ( I am using WAS 184.108.40.206 ) with a pair of standard profiles, AppSrv01 and AppSrv02.... [More]
High Availability (HA) Manager is a framework that allows singleton services to make themselves highly available. Transaction Log Recovery is one of the HA Manager users.
Every WebSphere Application Server process is a member of a HA Manager DCS CoreGroup. During server (cluster member) startup, transaction manager and other server components will also get started. Transaction Manager should have exclusive ownership of its transaction recovery log file before it can initialize successfully. HA... [More]

Starting with IBM Business Process Manager V8.5.0, the BPMConfig command is widely used to create, update, upgrade, migrate [8.5.5] or delete an IBM Business Process Manager deployment environment. This article provides some tips and points that require extra attention when you use this command. There are two parts to this article: the first part focuses on the different parameters to pass to the BPMConfig command and the second part covers some tips for configuration properties file used by this command.
