BPEL PM: Introduction
Oracle Fusion Middleware’s most important tool is BPEL PM which is heart of any integration
and SOA fication. If one tune this component, most of the performance related challenges will
go away.
BPEL PM uses database extensively to ensure state full behavior. BPEL PM uses two schemas –
SOAINFRA and MDS.
TO DO: Modify following
The following diagram elaborates on the different types of processes that you may have and
how you can optimize the runtime execution infrastructure for them. The diagram explores the
various considerations to keep in mind while setting infrastructure level properties such as
idempotency, dispatcher threads, nonBlockingInvoke, completionPersistPolicy, and
completionPersistLevel. For example, for an asynchronous and a durable process, caller
threads are allocated for each instance and all messages are persisted as the instance
dehydrates at multiple breakpoints. These kinds of processes would need a different tuning
than synchronous and transient processes that do not persist instances.
TO DO
Exhibit 1: BPEL Processes

1 BPEL PM Process Types
BPEL Processes can be classified on the basis of interface or dehydration.

1.1 By Interface
•
•

Synchronous: Two way invocation
Asynchronous: One way invocation

1.2 By Durability
•

•

Durable Process: Long running
o Has mid process breakpoint activities (Receive, onMessage, onAlarm, Wait)
o Or has non-idempotent invoke
o Or has non-blocking invoke
Transient Process: Short Running
o No mid process breakpoint activities (Receive, onMessage, onAlarm, Wait)
o And has non-idempotent invoke
o And has non-blocking invoke

Non-Blocking invoke means engine perform within FlowN in parallel. It is defaulted to be
blocking but can be set non-blocking.
15

2 Terminology
While reading through the BPEL PM documentation, one will encounter few terms.
•

•

•

•

Component: Examples of components include a BPEL process, a Mediator service, or a
BPMN process. Within JDeveloper, these components are the building blocks for
composite applications.
Composite: A composite consists of zero or more components. For example, a single
composite can include a BPEL component and two Mediator components. Composite
applications are packaged into a single JAR file that is deployed to the SOA
Infrastructure.
Service engine: Service Engines are the actual engines that run the code. There are
three main service engines—BPEL Service Engine, Mediator Service Engine, and BPMN
Service Engine. As their names imply, the BPEL Service Engine executes the BPEL code,
the Mediator Service Engine executes the Mediator code, and the BPMN Service Engine
executes the BPMN code.
SOA Infrastructure: The SOA Infrastructure is the underlying infrastructure, which is
comprised of the service engines and to which the composite applications are deployed.

3 Difference between ASYNC & SYNC BPEL
Code level difference between sync and async processes can be observed in .bpel , .wsdl and
composite.xml files
If one scans through the .bpel and .wsdl file of both sync and async the processes, there will not
be many differences.
Composite.xml
SYNC: In service part interface.wsdl and binding.ws references are there.
ASYNC: In service part interface.wsdl, binding.ws and binding.ws references are there.
.bpel File
SYNC: In Partner Link name, partnerLinkType, and MyRole are there.
ASYNC: In partner Link name, partnerLinkType, MyRole, and Partner Role are there.
.wsdl file
SYNC: In portType, Input & Output both are there , in partnerLinkType only one role is there i.e
Requester or Provider Role.
ASYNC: In portType only Input is there, in PartnerLinkType two roles are there, Provider
and Requester Role.
16

In SYNC process Reply activity is there while ASYNC has Invoke activity.

4 SOA 11g Configuration Files and Log Files Location
In the current section, middleware home and domain home are defined as:
- $ MIDDLEWARE_HOME =
- $ DOMAIN_HOME = $ MIDDLEWARE_HOME/user_projects/domains/

•

Domain configuration under $DOMAIN_HOME/config
- Config.xml
- jdbc/-Jdbc.xml
- jms/-Jms.xml files under

•

Adapter configuration under $MIDDLEWARE_HOME//soa/connectors/ ( Oracle_SOA1 is
the default name)
- AppsAdapter.rar
- DbAdapter.rar
- FtpAdapter.rar
- MQSeriesAdapter.rar
- SocketAdapter.rar
- AqAdapter.rar
- FileAdapter.rar
- JmsAdapter.rar
- OracleBamAdapter.rar

•

Admin Server log files under $DOMAIN_HOME/servers//logs
- Access.log
- -Diagnostic.log
- .log

•

SOA Server log files under $DOMAIN_HOME/servers//logs
- . log
- -Diagnostic.log

5 Default Data Sources
•
•

mds-soa - The MetaData Store connection used by the SOA Suite
SOADataSource - The data source used by the SOA Suite engine
17

•

SOALocalTxDataSource - the transaction aware data source used by the SOA Suite
engine.

These data sources are vital for the Oracle SOA Suite. Each will have a JNDI Name showing the
jndi location, eg: jdbc/SOADataSource; and each will list one or many targets, Weblogic
managed server defines a valid target.

6 Performance Objective
To tune a BPEL engine for a given load, first one has to understand performance objectives. To
determine performance objectives, one needs to understand the BPEL Engine and processes
deployed and the environmental constraints placed on the overall setup. Collect information
about the levels of activity that components of the BPEL Engine perform and expected to meet,
such as:
•
•
•
•
•
•

The anticipated number of composites/processes to be deployed in BPEL Engine;
The number and nature of calls to external resources (JMS, database, file system, AQ,
web services, etc.)in each deployed process/composite;
The size of message to be processed by each deployed process/composite;
The pattern of load on each process/composite individually as well as a system;
Target CPU utilization;
Target memory utilization.

7 What to Tune
The tuning for BPEL PM in 11g environment is multistep and multi-layer approach. Tuning and
LnP testing is series of steps and certainly not in serial fashion.
1. Determine tuning objectives
2. Understand and document underlying:
a. Weblogic App Server (WLS)
b. Database (SOA database)
c. JVM
d. Operating system, network infrastructure and hardware
e. Deployment topologies of JVM, WLS, BPEL Engine, databases, JMS, load
balancers, etc.
f. Monitoring scripts, toolsets, queries, analysis tools, etc.
g. Capacity, capabilities, performance and resilience of boundary system interfaces
3. Collect records w.r.t.
a. Historical load pattern in production
b. Estimated load projections for the life cycle of system under LnP test
c. Previously conducted LnP tests
d. Known issues with underlying infrastructure

8.

e. Known issues with BPEL processes/composites under LnP test
Understand and document BPEL processes:
a. Under test
b. Running on targeted infrastructure
Understand and document BPEL processes under test and infrastructure usage
a. Type of BPEL processes (Sync, Async), number of activities in BPEL processes,
number of listeners used, number of database connections, boundary system
user/session management used, etc
b. Set up of JMS (if used by BPEL processes under test)
c. Set up of database/schema
Set up the target load and performance (not as single point but multiple scenarios and
as bands). Employ Design of Experiment approach to select LnP test scenarios.
For example:
• Scenario 1: Under load XXX on service YYY (keeping constant load of ZZZ on all
other services) completion time for service YYY is AAA seconds (maximum) for
test duration of TTT hours.
• Scenario 2: Under load XXX on service YYY and load PPP on service QQQ (keeping
constant load of ZZZ on all other services) completion time for service YYY is AAA
seconds (maximum) for test duration of TTT hours.
• Scenario 2: Under max load of AAA and min load of BBB (sine wave of frequency
TTT hours) on service YYY (keeping constant load of ZZZ on all other services) the
Tune following:
a. JVM
b. WLS
c. JMS (if used)
d. BPEL processes/composites
e. OSB/load balancer (if used)
f. Database
g. BPEL engine
Data Collection
a. JVM usage ( heap, thread, garbage collection, etc) of BPEL server, JMS server
b. RAM usage pattern
c. CPU usage pattern
d. SOA database reports
e. Custom schemas database reports
f. Number of database connections usage pattern
g. Response time from boundary systems
h. JMS listeners usage pattern
i. Number of messages in JMS queues at each minute of LnP test
j. LoadRunner data (load pattern, performance reports, errors, etc)
19

k. Details of any issue arisen in network or database or any other system during
LnP run
l. Data from boundary systems
9. Data Analysis
a. Statistical analysis of data collected
b. Draw the result and recommend a new test with modifications in parameters
and/or load conditions
c. Correlate results with previous load & performance tests.

8 System Setup
In this book, following set is assumed until specified otherwise:
1.
2.
3.
4.
5.

BPEL PM version is 11.1.1.6.0 (select * from soainfra.label_version_pcbpel)
Enterprise has set up multiple WebLogic (v10.3.6.0) domains.
Each WebLogic domain has either BPEL server or JMS installed.
Weblog server is in clustered environment.
Database is installed on a rack (Oracle Database 11g Enterprise Edition Release
11.2.0.3.0 - 64bit Production).
6. Operating System is Red Hat Linux (rhel-1.39.1.9.7.el6-x86_64)
7. Java version is 1.7.0_05 (HotSpot 64-Bit Server)

It is also assumed that network, disk speed, CPU type and other hardware related factors will
not be hitting ceiling in any load conditions under consideration.

9 Important Points
While tuning a system just remember some important factors:
•
•

•

•

Performance tuning is not a silver bullet. Good system performance depends on: good
design, good implementation, defined performance objectives, and performance tuning.
Performance tuning is ongoing process. Implement mechanisms that provide
performance metrics which one can compare against performance objectives, allowing
scheduling a tuning phase before system fails.
The object is to meet performance objectives, not eliminate all bottlenecks. Resources
within a system are finite. By definition, at least one resource (CPU, memory, or I/O) will
be a bottleneck in the system. Tuning allows minimizing the impact of bottlenecks on
performance objectives.
Design applications with performance in mind.
