About Environment Variables for System Logging

The following system environment variables can be set to assist with logging other aspects of the Siebel application deployment. For information about configuring these environment variables on both Microsoft Windows and UNIX, see Siebel System Administration Guide or review the documentation specific to your operating system for details on changing these variables.

• SIEBEL_LOG_EVENTS. The SIEBEL_LOG_EVENTS environment variable sets the event logging level, which determines the extent of information captured in the log file. For level settings and descriptions of information captured, see Table 14. More information is captured when the environment variable is set to a higher numeric value, and less information is captured when the variable is set to a lower numeric value. The numeric value is inversely proportional to the severity of the information (0 is more severe than 5, for instance). More disk space is consumed and performance is hindered when the value is set to a value of 5 than a value of 0.
• SIEBEL_LOG_ARCHIVES. The SIEBEL_LOG_ARCHIVES environment variable determines the number of log files archived. Set this value to a positive integer; this value indicates the number of files that are saved. For example, if the value is 3, then only the three most recent log files are retained, any additional log files are deleted. When a new log is created, program.log, the previous versions are archived as program_1.log, program_2.log, and so on. The numbers in the filename increase as the file becomes Statistics older. The oldest log file that numbers past the integer setting is deleted. The default value of this variable is ten.
• SIEBEL_LOG_DIR. The SIEBEL_LOG_DIR environment variable determines the log file location. Set this variable to change the location from the default directory. Make sure this directory already exists, access permission to write a file in that location is available, and sufficient space is free to support the log file.
• SIEBEL_CRASH_HANDLER. The SIEBEL_CRASH_HANDLER environment variable enables the creation of files when there is a malfunction or failure. For information about these files, see About Other Siebel Server Log Files. The default setting is 1, which enables the creation of such files. Setting this variable to 0 disables this function. Only set this variable in consultation with Oracle Global Customer Support. For help with setting this variable, create a service request (SR) on My Oracle Support.
• SIEBEL_ASSERT_MODE. The SIEBEL_ASSERT_MODE environment variable enables the creation of assert files. For information about assert files, see About Other Siebel Server Log Files. The default setting is 0, which disables the creation of assert files. Only set this variable in consultation with Oracle Global Customer Support. For help with setting this variable, create a service request (SR) on My Oracle Support.
• SIEBEL_SESSMGR_TRACE. The SIEBEL_SESSMGR_TRACE environment variable enables tracing for session manager, which is part of the Siebel Application Interface. By default, this variable is set to 0, which logs fatal and error events to the Siebel Application Interface log file. For information about Siebel Application Interface log files, see About Siebel Application Interface Logging. To enable detailed logging of session manager, set this variable to 1. For more information about configuring logging for Siebel Application Interface, see Configuring Siebel Application Interface Logging.
• SIEBEL_SISNAPI_TRACE. The SIEBEL_SISNAPI_TRACE environment variable enables tracing for SISNAPI, which is a Siebel-proprietary communication protocol between the Siebel Application Interface and the Siebel Servers. By default, this variable is set to 0, which logs fatal and error events to the Siebel Application Interface log file. For information about Siebel Application Interface log files, see About Siebel Application Interface Logging. To enable detailed logging of SISNAPI, set this variable to 1. For more information about configuring logging for Siebel Application Interface, see Configuring Siebel Application Interface Logging.
• SIEBEL_STDERROUT. The SIEBEL_STDERROUT environment variable enables logging of the standard error files. For more information about standard error files, see Configuring Standard Error Files. By default, this variable is set to 0, which disables standard error file logging. To enable logging of standard error files, set this variable to 1.
