OPEN_CURSORS

This specifies the maximum number of open cursors (handles to private SQL areas) a session can have at once. You can use this parameter to prevent a session from opening an excessive number of cursors.

Oracle FLEXCUBE relevance

It is important to set the value of OPEN_CURSORS high enough to prevent FLEXCUBE application from running out of open cursors (ORA-01000: maximum open cursors exceeded).
