Monitor the shared-memory profile and latches

Monitor the database server profile to analyze performance and the use of shared-memory resources.

You can obtain statistics on latch use and information about specific latches. These statistics provide a measure of the system activity.

The ON-Monitor Profile screen maintains cumulative statistics on shared-memory use.

To reset these statistics to zero, use the onstat -z option. For a description of all the fields that onstat displays, see information about the onstat utility in the HCL OneDB™ Administrator's Reference.
