Tuning G1GC For SOA

Garbage-First Garbage Collector (G1GC) is a new GC Algorithm introduced in later version of JDK 1.7. Prior to the introduction of G1GC there have been 2 other GC Algorithms: ParallelGC and Concurrent Mark Sweep (CMS) algorithms. While ParalleGC was the choice for high throughput applications like SOA, CMS was the choice for applications requiring low […]

EDI Processing with B2B in hybrid SOA Cloud Cluster integrating On-Premise Endpoints

Executive Overview SOA Cloud Service (SOACS) can be used to support the B2B commerce requirements of many large corporations. This article discusses a common use case of EDI processing with Oracle B2B within SOA Cloud Service in a hybrid cloud architecture. The documents are received and sent from on-premise endpoints using SFTP channels configured using […]

B2B Event Queue Management for Emergency

Executive Overview Many customers face a crisis in production system when, for some reason, they end up with several B2B messages stacked up in the system, that may not be of a high priority to be processed at that point in time. In other words, it would greatly help many customers if, in such critical […]

Running Built-In Test Simulator with SOA Suite Healthcare 11g in PS4 and PS5

Background SOA Suite for Healthcare Integration pack comes with a pre-installed simulator that can be used as an external endpoint to generate inbound and outbound HL7 traffic on specified MLLP ports. This is a command-line utility that can be very handy when trying to build a complete end-to-end demo within a standalone, closed environment. The […]

B2B Agreement Life-Cycle Management, Part 2 – Best Practices for High Volume Deployment of Agreements

Introduction In Part 1 of the B2B Agreement Life-Cycle Management Series, we looked at the best practices to import high volume of agreement metadata into the repository [1]. In this post, we will take a look at the best practices to deploy the agreement metadata for run-time processing. Background B2B 11g supports the notion of […]

SOA Suite for Healthcare Integration startup errors due to expired passwords.

SOA Suite for Healthcare integration involves starting up the managed servers, which are in turn, dependent on valid connections to databases. In many low-maintenance environment like Virtualbox images distributed for training and worksh…

Oracle SOA for Healthcare – Setting Endpoint Acknowledgement Acceptance

Acknowledgment acceptance in SOA Suite for Healthcare is globally set through the console at the document level. Currently there is no way to override the global setting for an endpoint in the SOA for Healthcare console. The illustration below shows acknowledgment acceptance being set in the document type definition in the SOA for Healthcare console

Oracle B2B – b2b.rowLockingForCorrelation

In cases where the latency between the outbound EDI document and the subsequent inbound acknowledgment is very low, a race condition will likely occur when B2B tries to update the document state in the B2B_BUSINESS_MESSAGE table. The result is the status of the original EDI document remains in either a MSG_WAIT_FA or MSG_WAIT_ACK state indefinitely if no retry value has been set, or it evolves to a state of MSG_ERROR after the retry interval and all the retry attempts have expired.

B2B Agreement Life-Cycle Management, Part 1 – Best Practices for High Volume CPA Import Operations with ebXML


B2B 11g supports ebXML messaging protocol, where multiple CPAs can be imported via command-line utilities. 

This note highlights one aspect of the best practices for import of CPA, when large numbers of CPAs in the excess of several hundreds are required to be maintained within the B2B repository.


The import of CPA usually is a 2-step process, namely creating a soa.zip file using b2bcpaimport utility based on a CPA properties file and then using b2bimport to import the b2b repository.  The commands are provided below:

  1. ant -f ant-b2b-util.xml b2bcpaimport -Dpropfile=”<Path to cpp_cpa.properties>” -Dstandard=true
  2. ant -f ant-b2b-util.xml b2bimport -Dlocalfile=true -Dexportfile=”<Path to soa.zip>” -Doverwrite=true

Usually the first command completes fairly quickly regardless of the number of CPAs in the repository. However, as the number of trading partners within the repository goes up, the time to complete the second command could go up to ~30 secs per operation. So, this could add up to a significant amount, if there is a need to import hundreds of CPA in a production system within a limited downtime, maintenance window. 


In situations, where there is a large number of entries to be imported, it is best to setup a staging environment and go through the import operation of each individual CPA in an empty repository. Since, this will be done in an empty repository, the time taken for completion should be reasonable. 

After all the partner profiles have been imported, a full repository export can be taken to capture the metadata for all the entries in one file. 

If this single file with all the partner entries is imported in a loaded repository, the total time taken for import of all the CPAs should see a dramatic reduction.


Let us take a look at the numbers to see the benefit of this approach. With a pre-loaded repository of ~400 partners, the individual import time for each entry takes ~30 secs. So, if we had to import another 100 partners, the individual entries will take ~50 minutes (100 times ~30 secs). On the other hand, if we prepare the repository export file of the same 100 partners from a staging environment earlier, the import takes about ~5 mins.

The total processing time for the loading of metadata, specially in a production environment, can thus be shortened by almost a factor of 10.


The following diagram summarizes the entire approach and process.

Oracle B2B – Synchronous Request Reply

Beginning with Oracle SOA Suite PS5 (, B2B supports synchronous request reply over http using the b2b/syncreceiver servlet. I’m attaching a demo to this blog which includes a SOA composite archive that needs to be deployed using JDeveloper, a B2B repository with two agreements that need to be deployed using the B2B console, and a test xml file that gets sent to the b2b/syncreceiver servlet using your favorite SOAP test tool

Using Oracle B2B to send binary documents

Often times in
a demonstration or a POC, B2B is asked to transport binary encoded
files. This is actually very easy to do, but there are a number of
restrictions you should be aware of when considering whether to use
B2B for this or not.

Bidirectional Translation Web Services are now available in B2B 11g PS5 Release

Starting from SOA Suite PS5, bi-directional translation via web service is now available within the
base install of B2B 11g. The note here describes the basic usage details.

How to disable B2B

That’s a provocative title!  Let’s start by talking about why you might want to disable B2B! If you are using BPM (or SOA) and you are not using any of the B2B functionality, then you might want to consider disabling … Continue reading
