BPEL & ESB server settings

In case of BPEL the domain level settings are located in the Oracle_Home\bpel\domains\domain_name\config\domain.xml file. For configuring the BPEL server few options are only listed in the BPEL Console. There are many other properties also which you can set by editing the domain.xml.Once you edit the domain.xml , the new settings will take effect only after you restart the Oracle BPEL Server .Given below are some of the important domain level settings

optCacheOn - This property sets the in-memory cache for in-flight instances.

instCachePolicy - This property sets the eviction policy to use when removing in-flight instances from the cache.

instCacheHighWatermark - This property sets the maximum number of in-flight instances that can be placed in the cache before pruning occurs

instCacheLowWatermark - This property sets the number of in-flight instances to which the cache is pruned when pruning occurs.

dspMaxThreads - This property sets the maximum number of active dispatcher threads that process messages during peak load times

deliveryPersistPolicy - This property enables and disables database persistence of messages entering Oracle BPEL Server

auditLevel - This property sets the audit trail logging level. This process is applicable to both durable and transient processes.

auditDetailThreshold - This property sets the maximum size (in kilobytes) of an audit trail details string before it is stored separately from the audit trail.

workerQueueConnectionPoolMinSize - This property sets the worker queue connection pool minimum size. This value must match the number of worker threads

invokerQueueConnectionPoolMinSize - This property sets the invoker queue connection pool minimum size. This value must match the number of invoker threads

bpelcClasspath- This property sets the BPEL process compiler classpath.(very useful in WSIF)

For BPEL related errors domain.log @ Oracle_Home\bpel\domains\default\logs will come in handy

In case of ESB the main configuration file is esb_config.ini @ Oracle_Home\ integration\esb\config\ esb_config.ini

cluster_name - The default name of cluster for all the processes.

primary_oc4j- In case of cluster configuration this property is commented out .By default value is true

xa_timeout – the default value for JTA timeout

jms_receive_timeout – the timeout configured for JMS receive timeout (in seconds)

esbSystemForBPEL – the system name for BPEL processes

InboundRetryCount - This property sets the inbound retry count

InboundRetryInterval - This property sets the inbound retry interval

InboundRetryEnabled - This property sets the inbound retry is enabled

OutboundRetryCount - This property sets the outbound retry count

OutboundRetryInterval - This property sets the outbound retry interval

OutboundRetryEnabled - This property sets whether outbound retry is enabled

For ESB related errors log.xml @ Oracle_Home\ j2ee\home\log\home_default_group_1\oc4j will come in handy
