This chapter describes how to troubleshoot Oracle Communications WebRTC Session Controller installations.
The WebRTC Session Controller Signaling Engine (Signaling Engine) installer and the Domain Configuration Wizard write information to log files. You can check those log files for information about errors and actions performed during the installation.
The Signaling Engine installation logs can be found at Central_inventory_location/oraInventory/logs, where Central_inventory_location is the directory path to the oraInventory directory. If you do not know the location of your Oracle Inventory directory, you can find it in the oraInst.loc
file in the directory, /etc/oraInst.loc.
The following install log files are written to the log directory:
install
date-time-stamp
.log
This is the main log file.
install
date-time-stamp
.out
This log file contains the output and error streams during the installation.
installProfile
date-time-stamp
.log
This log file contains the overall statistics like time taken to complete the installation, as well as configuration, memory and CPU details.
oraInstall
date-time-stamp
.log
This log file contains the output stream of the copy session.
oraInstall
date-time-stamp
.err
This log file contains the error stream of the copy session.
Use the -logLevel
parameter from the command line when you start the installer. For example:
java -jar wsc_generic.jar -logLevel info
Valid value for -logLevel
are listed below from most detailed to least detailed:
severe
warning
info
config
You can also specify logging details from detailed to least detailed in the following manner:
fine
finer
finest
If you encounter errors when configuring a Signaling Engine domain, you can start the Fusion Middleware Configuration Wizard with the appropriate logging options.
To enable domain configuration logging, navigate to Oracle_home/oracle_common/common/bin and start config.sh
with the -log
and -log_priority
options:
./config.sh -log=log_filename -log_priority=log_level
Table 16-1 describes the -log
and -log_priority
options.

WebRTC Session Controller Media Engine (Media Engine) implements specialized troubleshooting commands that can be executed at the console command line interface (CLI).
For detailed troubleshooting instructions, see the discussion of Media Engine system monitoring in Oracle Communications WebRTC Session Controller System Administrator's Guide.
You can use the following CLI command to display events logged to the Media Engine's local database:
show event-log
Information in the Media Engine event log can provide details on software errors, connectivity issues, and incorrectly configured objects and properties.
You can use the following CLI command to display any software subsystem faults:
show faults
In conjunction with configuration files, traces and event logs, information for the show faults command can be used to troubleshoot system issues.
