问题 Is there any way to uniquely identify current session in GV$SESSION view in Oracle? I've faced with the problem that the following query may return more than one row in case of Oracle RAC configuration: SELECT SID, SERIAL# FROM GV$SESSION WHERE AUDSID = Sys_Context('USERENV', 'SESSIONID') AND SID = Sys_Context('USERENV', 'SID'); Using V$MYSTAT is not an option either, because V$MYSTAT may not be accessible for the current session (for example when statistic is disabled). 回答1: Try this: SELECT
