Trace logging in AIA is enabled via configurations in the AIAConfigurationProperties.xml file located in <AIA_HOME>/aia_instances/$INSTANCE_NAME/AIAMetaData/config directory.
Logging can be set at the system or service level. The logging property set at the service level overrides the property set at the system level. To enable trace logging for the entire system follow below steps:
1. Access the AIAConfigurationProperties.xml file.
2. Set the TRACE.LOG.ENABLED property at the system level to true.
3. Update the file back to MDS
4. Reload updates to AIAConfigurationProperties.xml from configuration page of AIA Console.
In the BPEL code, trace logging is added by inserting Java Embedding activities. These activities basically call the AIA trace logging functions : isTraceLoggingEnabled and logTraceMessage. If you are using AIA Service constructor for ABCS development, this piece of code is auto-generated for you.
The Oracle AIA trace and error log files can be accessed from EM Console or directly from file system:
$MW_HOME/user_projects/<domain_name>/servers/soa_server1/logs/aia-error.log
$MW_HOME/user_projects/<domain_name>/servers/soa_server1/logs/aia-trace.log
The logging level like logLevel Severe, Warning, Info, Fine, Finest etc. can also be configured from EM Console.
