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 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 Have you ever wondered how to control/configure the metricdump log files that accumulate in your WebLogic Server domains configured with Fusion Middleware? This blog will help to answer that question. Main Article When running WebLogic Server instances configured with Fusion Middleware (e.g., SOA Suite), there are Dynamic Monitoring Service (DMS) metrics that are gathered every 3 hours by default. These metrics are located in the...

This blog has been retired Introduction This blog will show you how to debug Oracle EDN (Event Delivery Network) and also describes the tools that can be used to debug EDN. Main Article 1. Using EDN-DB-LOG EDN comes with a useful EDN DB logging servlet to view logging information generated by the EDN component. This logging servlet is only available for EDN-DB which is based on AQ, it will not work for EDN with JMS. The servlet uses a table called “EDN_LOG_MESSAGES” in the...

This blog has been retired Introduction The mediator supports three modes, for instance, tracking by changing the audit level in EM->SOA->SOA-INFRA->SOA Administration->Mediator Properties: Off - No instance tracking for successfully completed instance, however, instances and faulted instances are created even in this mode. An audit trail will not be created with this flag. Production - Instance tracking is enabled for all. All audit details are logged, except the details...

Summary This blog describes how to enable transitive probe-based failure detection. Main Article On Exalogic, no matter which supported Operating Systems that a compute node is running, it relies on the IB gateways (NM2-GW) to provide both internal (IPoIB) and external (EoIB) network connectivity. Each compute node is physically connected to two IB gateways by copper cables, the IB gateway in turn is connected to customer's 10GbE infrastructure, typically a level 2 switch. By...

Introduction From time to time, you may experience some kind of issue in your BPM environment. Issues could be caused by a wide variety of reasons – changes to the environment, the pattern of load on the environment, product defects, bad process design, insufficient resources allocated to the environment, network instability – just to name a few! Main article When something goes wrong, it is important to know how to collect the diagnostic information that will be needed to...

Introduction This post provides a programmatic way to disable an OSB endpoint and trigger that code automatically using an OSB alert rule. Main Article From the design practice point of view, it is always recommended to make your endpoint highly available. With the help of either load balancer or OSB's failover capability across multiple endpoints, you should be able to make your OSB safer and less vulnerable from endpoint errors. In addition, you'd better implement OSB best...
