These threads allow the requests to be processed in parallel. The BAM Adapter does not have many properties that can be tuned, but we do look at one improvement here that can improve performance. How to do it To set the Parallel Metrics Level property, perform the following steps: 1. Log in to the Enterprise Manager. Expand the SOA section in the left-hand pane, and right-click on soa-infra. You will now see the SOA properties page. Set the Metrics Level property to Disabled. How it works By default, the Mediator engine will collect metrics from the execution of composite instances, and make them available via the DMS.
If you do not make use of these metrics, then there is little point collecting them, and by removing them, performance can be improved. To set the Parallel Worker Threads property, perform the following steps: 1. Set the property Parallel Worker Threads to a larger value, such as The Parallel Worker Threads property determines the number of threads available for processing parallel routing rules.
If you have many parallel routing rules defi ned in your application, then the default value of 4 may not be suffi cient; so you can increase the number of threads to allow more parallel rule requests to be processed concurrently. The following steps will allow us to set the Parallel Maximum Rows Retrieved property: 1. Set the property Parallel Maximum Rows Retrieved to a larger value, such as The Parallel Maximum Rows Retrieved property determines how many rows are read from the Mediator store database when loading pending parallel rule execution requests.
By loading more rows at a time, the number of trips to the database can be reduced, improving performance; however, this will only have an effect if there are usually multiple requests waiting to be processed. The default is rows, so you will need to have a busy system with lots of parallel Mediator rules, in order to see any improvement from increasing this value. To set the Parallel Locker Thread Sleep time, perform the following steps: 1. While parallel routing rules do allow for truly asynchronous processing in the Mediator, the way that they are processed is not intuitive.
A daemon thread is used to check the Mediator store database for requests to be processed, and checks each parallel rule in turn.
If there are requests to be processed for a rule, then exactly one request will be processed for that rule using a Mediator worker thread. After it has checked all the parallel rules and executed one request for each that has pending requests , the thread will sleep for a period of seconds defi ned by the Parallel Locker Thread Sleep time.
By default this value is 2 seconds, but performance can be improved if you are using parallel routing rules by decreasing this to 1 second the lowest value allowed. Note that the daemon thread does not execute the requests; it is just used to check which rules have pending requests, and assign them to worker threads. This seemingly strange approach is used to prevent a very busy parallel rule from hogging all of the worker threads, thus starving other rules of the threads they need, and potentially causing performance bottlenecks.
You will need write access to the fi les in your SOA Suite domain for this recipe. The confi guration fi les are not created until the server is fi rst started, so you will need to start the server before you are able to edit the fi les.

Because Oracle SOA Suite 11g builds on top of a variety of infrastructure components, up until now there has been no one single complete reference that brings together all the best practices for tuning the whole SOA stack.
Starting with how to identify problems, and building on that with sections on monitoring, testing, and tuning, the recipes in this book will take you through many of the options available for performance tuning your application. There are many considerations to make when trying to get the best performance out of the Oracle SOA Suite platform.
This book focuses on bringing together tips on how to identify the key bottlenecks in the whole SOA Suite infrastructure, and how to alleviate them. The Oracle SOA Suite 11g Performance Tuning Cookbook will ensure that you have the tools and techniques to get the most out of your infrastructure, delivering reliable, fast, and scalable services to your enterprise.
