Introduction When leveraging the Oracle Database Adapter (DB Adapter) using the Distributed Polling feature, understanding what is going on under the covers can help with the tuning effort. This blog will attempt to demystify the configuration and behavior of Distributed Polling with SKIP LOCKED. Main Article Oracle SOA Suite 11g offers a set of Java EE Connector Architecture (JCA) technology adapters for various integration scenarios. One of the more common scenarios is...

Note: This article provides an approach to implement compression in OSB 11g. OSB 12c supports compression OOTB. For details please refer to the following documentation: Compressed HTTP Request and Response Payload Support HTTP compression is a mechanism that enables client and server to exchange compressed data over HTTP to improve performance by better use the bandwidth. Oracle Service Bus (OSB) doesn't support gzip compression by default, this might create a potential...

Introduction This document will detail how to calculate maximum disk read and write rates for a single process using the UNIX "dd" and "time" commands. Not covered in this document are performance differences using different RAID (redundantly arrayed independent disks) configurations, limitations of the system bus speeds and limitations of controller buffer speeds. Main Article Perhaps the most common bottleneck for replication is the speed at which data can be read from and...

Introduction This technical document describes how to combine the GoldenGate logdump utility, UNIX shell scripting and MS Excel to generate a detailed summary report to aid in manual load balancing of tables across multiple GoldenGate replication processes. This document is not intended to be a comprehensive overview of all replication performance techniques; it is limited to the usage of logdump to collect table level statistics, how to import those statistics into a...

Introduction The purpose of this document is to outline the file system mount options to use when configuring GoldenGate to run with NFS mounted file system. Main Article Unless IO buffering is OFF, NFS mounts should not be used when running any Oracle GoldenGate processes. The danger occurs when one process registers the end of a trail file or transaction log and moves on to the next in sequence before all the data in the NFS IO buffer gets flushed to disk. The net result...

Introduction Typically, a Service Oriented Architecture (SOA) system has multiple and different services receiving the same type of messages. For example, a purchase order can trigger either creation or modification of an order, which may be handled by different business flows connecting to different back-end systems. Ideally, you provide to the outside world a coarse grain service for order creation, and another coarse grain service for order modification, etc, so that an...

Introduction A critical performance tuning parameter for Oracle Service Bus (OSB) is the setting for RouterRuntimeCache. The following article describes this parameter and the impact of changes to it. Main Article Many customers start out with smaller projects for an initial release. Typically, these applications require 20-30 Proxy services. But as time goes on and later phases of the project rollout, the number of proxy services can increase drastically. The...

Introduction This is an old, Oracle SOA and OC4J 10G topic. In fact this is not even a SOA topic per se. Questions of RMI load balancing arise when you develop custom web applications accessing human tasks running off a remote SOA 10G cluster. Having returned from a customer who faced challenges with OC4J RMI load balancing, I felt there is still some confusion in the field of how OC4J RMI load balancing works. Hence I decide to dust off an old tech note that I wrote a few...

Introduction My earlier blog posting shows how to enable, retrieve and interpret BPEL engine performance statistics to aid performance troubleshooting. The strength of BPEL engine statistics in EM is its break down per request. But there are some limitations with the BPEL performance statistics mentioned in that blog posting: The statistics are stored in memory instead of being persisted. To avoid memory overflow, the data are stored to a buffer with limited size. When the...
