GemFire functions offers a powerful and flexible way to send distributed work to multiple servers, where this work can be data-dependent as smart units of work that act in parallel on a given region or parallel on all available members of the system. This work can even be filtered to only work on a set … Continue reading GemFire functions with Java 8, Nashorn and Groovy

Just finished to install SOA Suite 11.1.1.3 with OSB 11g. Later I’ll post about other details regarding the new versions (I have tons of links to share) but for now, needed to right after installation modify the setSOADomainEnv.sh script to use less memory for AdminServer, which is not a problem in a local development machine. … Continue reading SOA Suite 11.1.1.3 AdminServer memory adjust
For those who needs to look at some huge log files (usually generated by Java servers such as weblogic, tomcat or jboss…) or needs to check thread dumps (stuck thread sucks) here goes a great tool: TDA (Thread Dump Analyzer).
In a JEE architecture we have a daily work with multi-thread environments. All applications (or most of them) needs to run in cluster and share the load between many machines, domains, work managers or threads. In such scenarios, it’s important to identify which class made a thread stuck ? What’s going on in the JVM in the moment the application stops working and freeze. In such situations, you can take a look at the thread dump. But what is a thread dump ? In few words: a textual dump of all active threads and monitors of Java apps running in a Virtual Machine.
Of course there are much more to say about thread dumps, but today I’m just posting about a tool that can helps working thread dumps and some server side logs… TDA! (not a sound)
Here are the new features listed from TDA home:
