A fundamental troubleshooting technique is to enable and use debugging information in product log files. Use this technique before calling Technical Support so that you can provide specific information about your issue. See Using EPM System Logs.
Check log files in these locations:
EPM_ORACLE_HOME/diagnostics/logs–Installation-time logs
EPM_ORACLE_INSTANCE/diagnostics/logs–Configuration-time logs, service startup logs, and runtime logs for service components
MIDDLEWARE_HOME/user_projects/domains/domain name/servers/managed server name/logs–Web application runtime logs
Central Inventory/logs–Oracle Universal Installer (OUI) and OPatch logs
EPM_ORACLE_INSTANCE/diagnostics/logs/upgrades–Upgrade logs
