Diagnosing and Resolving Issues in Oracle Business Intelligence 8-17 Writer implementation The following implementations are defined: ■ FileLogWriter. Writes to a disk file. ■ CoutWriter. Writes to standard output. ■ EventLogWriter. Writes to a Windows event log or UNIX syslog. ■ CrashWriter. A Windows only facility that writes to a crash dump file when Presentation Services attempts to log from a specific source file and line number. Used in a production environment for information of some loggable but irrecoverable error for example, failed NQTEST. Note: Use this implementation with care as it might leave the server in an unstable state. Use this implementation in very rare diagnostic-only scenarios on a test system. On Windows, CrashWriter requires the appropriate version of dbghelp.dll at least 6.0.17.0. The correct dbghelp.dll can be found in supportwindowssystem32. Put this DLL in the WINNTsystem32 or in the mainbin directory. No registration is required. Writer name Unique name for the writer. Writer writerClassId Specifies an integer number in the range 1 through 10. This number is used by filters to allow or prohibit logging. Each distinct writer must have a unique value, which is used later for filter configuration. Different writers might have the same class ID, but if they do, those writers cannot be distinguished by filters. Writer fmtName Optional Specifies the format of logged messages. Valid values are: ■ default - 10g style . Formats messages with identifying headings. ■ ODL-TEXT . Formats messages in Oracle Diagnostic Text format. ■ ODL-XML . Formats messages in Oracle Diagnostic XML format. If you do not set this attribute, then logged messages are displayed in the default format which for file log writers is 10g style and for console is ODL-TEXT. See Section 8.5.3, Examples of the Formats of Logged Messages for examples. Writer FileLogWriter specific attribute dir Specifies the directory where log files are created. Table 8–3 Cont.
