onstat -g stm command: Print SQL statement memory usage

Use the onstat -g stm command to display the memory that each prepared SQL statement uses.

By default, only the DBSA can view onstat -g stm syssqltrace information. However, when the UNSECURE_ONSTAT configuration parameter is set to 1, all users can view this information.


Syntax:

>>-onstat-- -g--stm--------------------------------------------><

To display the memory for only one session, specify the session ID in the onstat -g stm command.

Example output

 AND t1_key = ? AND t1_short = ?
