Command-line utilities to monitor shared memory and latches

Use command-line utilities to monitor shared memory and latches.

You can use the following command-line utilities to monitor shared memory and latches:

onstat -s: Use onstat -s command to obtain latch information.
onstat -p: Run onstat -p to display statistics on database server activity and waiting latches (in the lchwaits field). For an example of onstat -p output, see information about the onstat utility in the HCL OneDB™ Administrator's Reference.
