ERP LN Utilities

Oracle on Windows is integrated with the Event Viewer and Performance Monitor utilities on Windows.

The Event Viewer utility determines how system-alert messages appear on Windows. Oracle has integrated with Event Viewer to display Oracle startup and shutdown messages and the OS audit trail if you configure OS auditing in Oracle in the Event Viewer.

Performance Monitor is the Windows sar utility suite, which provides detailed resource utilization data for all processes that run on the system. Oracle has integrated with Performance Monitor to enable viewing utilization of operating system and Oracle resources, such as file write bytes per second related to Oracle or library-cache hit-ratios. The Oracle Performance Monitor icon in the Oracle group starts the standard Windows Performance Monitor utility but feeds the utility Oracle-specific data.

Note

The Windows Performance Monitor and Event Viewer utilities recognize only one Oracle instance on Windows. The only Oracle instance recognized by Windows is the instance defined by the registry entry:

HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE/ORACLE_SID

Although you can run multiple instances of Oracle on Windows, only the one identified by the ORACLE_SID value in the registry is visible to the Performance Monitor, Event Viewer, and Server Manager
