Hi All, We are running Oralce 8.1.7. on HP-UX . Recently I traced a application (third party) and I see some the following information in the trace file . ===================== PARSING IN CURSOR #6 len=181 dep=0 uid=8564 oct=6 lid=8564 tim=1314794115 hv=1049137217 ad='712a38b0' UPDATE SIEBEL.S_EVT_ACT SET LAST_UPD_BY = :1, MODIFICATION_NUM = :2, APPT_START_DT = :3, LAST_UPD = :4 WHERE ROW_ID = :5 AND MODIFICATION_NUM = :6 END OF STMT PARSE #6:c=0,e=0,p=0,cr=0,cu=0,mis=0,r=0,dep=0,og=3,tim=1314794115 EXEC #6:c=0,e=1,p=0,cr=4,cu=27,mis=0,r=1,dep=0,og=3,tim=1314794116 WAIT #6: nam='SQL*Net message to client' ela= 0 p1=1413697536 p2=1 p3=0 WAIT #6: nam='SQL*Net message from client' ela= 0 p1=1413697536 p2=1 p3=0 EXEC #9:c=0,e=0,p=0,cr=0,cu=4,mis=0,r=1,dep=0,og=3,tim=1314794116 WAIT #9: nam='SQL*Net message to client' ela= 0 p1=1413697536 p2=1 p3=0 WAIT #9: nam='SQL*Net message from client' ela= 1 p1=1413697536 p2=1 p3=0 XCTEND rlbk=0, rd_onfiltered=0 WAIT #0: nam='log file sync' ela= 0 p1=170 p2=0 p3=0 WAIT #0: nam='SQL*Net message to client' ela= 0 p1=1413697536 p2=1 p3=0 *** 2004-06-10 13:55:28.184 WAIT #0: nam='SQL*Net message from client' ela= 36301 p1=1413697536 p2=1 p3=0 ===================== From the trace output I can see that Parse#6,Fetch#6,WAIT#6 are attributed to Curosr #6 . But I am not able to figure out what event is invoking the WAIT#9 and WAIT # 0 . Also I am not able to figure out what event is causing this huge wait (363.01 secs) on SQL*Net message from client . Can somebody please explain me whats going on here. TIA, Madhu --------------------------------- Do you Yahoo!? Take Yahoo! Mail with you! Get it on your mobile phone.
