To access the Log Viewer, click on the log viewer link. This viewer is the viewer of WLDF. See WebLogic - Diagnostics Framework (WLDF)

5 - Execution Context ID (ECID)

When log entries for error messages and warnings are generated across multiple log files, they can be difficult to trace. However, it is possible to view logging information for specific user transactions across multiple log files. Transaction level logging associates a unique transaction ID, which is called the Execution Context ID (ECID)

6 - Diagnostic log files

Diagnostic log files are files used to store message information that is generated by Oracle Business Intelligence servers.

These log files are stored in the following location:

ORACLE_INSTANCE\diagnostics\logs\component_type\coreapplication

where component type is one of the following:

The following diagnostic log files are used in Oracle Business Intelligence: Where <n> = date and timestamp for example 20101209-2135

Component Log Files Description Searchable in Log Viewer

Oracle BI Server utilities - For example, biserverxmlexec and equalizerpds, also generate their own logs when they are run.

NQSUDMLExec.log ORACLE_INSTANCE\diagnostics\logs\OracleBIServerComponent/coreapplication_obis1
obieerpdmigrateutil.log (Migration log) ORACLE_INSTANCE\diagnostics/logs/OracleBIServerComponent/coreapplication_obis1
webcatupgrade.log (Web Catalog Upgrade) ORACLE_INSTANCE\diagnostics/logs/OracleBIPresentationServicesComponent/coreapplication_obips1
ODBC.log ORACLE_INSTANCE\diagnostics/logs/OracleBIODBCComponent/coreapplication_obips1
Upgrade Assistant log FMW_HOME\Oracle_BI1/upgrade/logs

Opmn generate also its own log files in the instance.
