Different Versions of Rete Algorithm
Rete Algorithm has different enhanced form of variations. Charles L. Forgy had worked on three versions which exhibited more performance and fastness in the systems. They are Rete II, Rete III, and Rete NT. Although there are other enhanced versions of Rete by different vendors like RetePlus by IBM and ReteOO by RedHat, they are not considered.
Rule Engine Execution Mode – Choosing and Setting in ODM
IBM Operational Decision Management has three Rule Engine Execution modes. The tricky part comes while choosing the appropriate execution mode for the rules in the rule task. To choose the correct execution mode, we should consider all the rules in the rule task.
Rete Algorithm is an efficient pattern matching algorithm that compares a large collection of patterns to a large collection of objects. It was invented by Charles L. Forgy and documented in his Ph.D. thesis in 1978-79 at Carnegie-Mellon University.
Initializing IBM RAD/RSA – eclipse.ini
IBM has a mega line up in the IDE business. Some of the IDEs provided by IBM are Eclipse, Rational Application Developer, Rational Software Architect Designer, Rational Business Developer, etc, When it comes to enterprise java development or operational decision management or business modelling, people use mostly RAD/RSA.
IBM Operational Decision Management(ODM) Performance Tuning – JVM
JVM tuning is important for IBM ODM (Operational Decision Management) because Decision Server Rules and Decision Server Events are both Java Platform, Enterprise Edition (Java EE) applications that run on WebSphere Application Server. Optimal performance is, therefore, dependent upon the correct tuning of Decision Server, WebSphere Application Server, and the underlying JVM.
IBM WebSphere Application Server Garbage Collection Policies
As long as an object is being referenced, the JVM considers it alive. Once an object is no longer referenced and therefore is not reachable by the application code, the garbage collector removes it and reclaims the unused memory. Java implicitly collects the garbage when objects are no longer referenced or when Java heap is insufficient and unable to satisfy a request for storage, such as object creation, it automatically triggers garbage collection to free memory.
Categorising a website in Websense / Forcepoint
When we own a website, we have to make sure that our website is accessible from all the systems without any sort of proxy blocking. I work in a software organization, which uses Websense/Forcepoint, a security solution for the organization’s network.
Roadmap for Upgrading to Java SE7 Programmer II (1Z0-805)
People who are already certified for Java SE6 or below versions(Sun Certified Java Programmer-SCJP or Oracle Certified Java Programmer-OCJP) can upgrade to OCP Java SE7 Programmer II. This particular exam 1Z0-805 covers only certain topics.
Roadmap for OCP Java SE7 Programmer II (1Z0-804)
As I have discussed in the previous post, I have collected all the topics that we should get prepared for getting certified as Oracle Certified Professional Java SE7 Programmer II. All the topics of OCA are included in the OCP certification plus some more additional topics.
Roadmap for OCA Java SE7 Programmer I (1Z0-803)
When I have started preparing for the Java Certification(Oracle Certified Associate Java SE 7 Programmer 1Z0-803), I couldn’t find the topics that should be prepared for the exam. After the referring to the many friends and books, I got the list of topics that we should get prepared.
Java Certification by Oracle – JAVA SE
Getting certified by Oracle will become an add-on for any professional. I gave a serious thought about getting certified by Oracle in java by preparing for it. I will be sharing all my knowledge with you daily through my posts.
Rule Engine Execution Modes
The execution of the rules inside the rule engine of IBM Operational Decision Management follows three rule engine execution modes – RetePlus, sequential, and Fastpath execution modes. Execution mode affects which rules are executed and in which order. Execution mode specifies the algorithm used by the rule engine inside Decision Server.
