To check the Business Space target services configuration in the administration console,
complete the following steps.
1. Open the IBM Business Process Manager Integrated Solutions Console.
2. Click the Servers tab in the navigation bar.
3. Click WebSphere.
4. Click Application Servers server type and choose the application server on which you
want to run Business Space.
5. In the Business Integration section on the Configuration tab, click the Business Space
Configuration entry.
6. On the Business Space Configuration page, in the Additional Properties section, click
the REST service endpoint registration entry.
7. On the REST service endpoint registration page, check the Service Endpoint Target
values for the Process services and Task services REST endpoint types. The default initial
setting is Federated REST services.
To improve performance by using the BPC REST End Point instead of the Federated REST
Endpoint, complete the following steps:
1. Change the Business Space target services configuration in the administration console.
2. Change the Process services to the Business Process Choreographer REST services
endpoint of the application server that is running your processes and human tasks.
3. Change the Tasks services to the Business Process Choreographer REST services
endpoint of the application server that is running your processes and human tasks.
4. Click OK to save the configuration changes.
5. Log out of Business Space and then log in again.
4.7.8 Power management tuning
Power management is common in modern processor technology. Both Intel and POWER core
processors have this capability. This capability delivers obvious benefits, but it can also
decrease system performance when a system is under high load, so consider whether to
enable power management. For example, with IBM POWER6® hardware, ensure that Power
Saver Mode is not enabled unless that is what you want. One way to modify or check this
setting on AIX is through the Power Management window on the Hardware Management
Console (HMC).
4.7.9 Setting AIX threading parameters
The IBM JVM threading and synchronization components are based on threads
implementation that are compliant with AIX POSIX. The following environment variable
settings improve Java performance in many situations. The variables control the mapping of
Java threads to AIX native threads, turn off mapping information, and allow for spinning on
mutually exclusive (mutex) locks:
► export AIXTHREAD_COND_DEBUG=OFF
► export AIXTHREAD_MUTEX_DEBUG=OFF
► export AIXTHREAD_RWLOCK_DEBUG=OFF
► export AIXTHREAD_SCOPE=S
► export SPINLOOPTIME=2000
