Administrative Utilities
The onstat utilityThe onstat utility reads shared-memory structures and provides statistics about the database server at the time that the command runs.
onstat -g monitoring optionsThe options that you can use with onstat -g command are used for support and debugging only. You can include only one of these options in the onstat -g command.
onstat -g dll command: Print dynamic link library file listUse the onstat -g dll command to display a list of and the status of dynamic link library (DLL) files that were loaded.

onstat -g dll command: Print dynamic link library file list

Use the onstat -g dll command to display a list of and the status of dynamic link library (DLL) files that were loaded.

Figure 1: Syntax:

Example output

The output displays the names of the library files only one time each process group. The flags indicate if the library was loaded when the server was started.
