RMAN
Home >RMAN > Monitorare stato dei processi rman
In un database Oracle 10.2 è stato lanciato uno script rman per avanzare l'SCN relativo all'ultimo archivelog catalogato: rman> run{ allocate channel c1 type disk; allocate channel c2 type disk; allocate channel c3 type disk; allocate channel c4 type disk; SET UNTIL SCN 14745913498; recover database; } Per verificare l'andamento e la durata del processo si può utilizzare V$SESSION_LONGOPS SELECT SID, SERIAL#, CONTEXT, SOFAR, TOTALWORK, ROUND(SOFAR/TOTALWORK*100,2) "%_COMPLETATA",OPNAME FROM V$SESSION_LONGOPS WHERE TOTALWORK != 0 AND SOFAR <> TOTALWORK; SID SERIAL# CONTEXT SOFAR TOTALWORK %_COMPLETE OPNAME ---------- ---------- ---------- ---------- ---------- ---------- ---------------------------------------------------------------- 867 1 1 1812456 3987015 45.46 RMAN: archived log restore Se si esclude l'ultima clausola: AND SOFAR <> TOTALWORK vengono visualizzati anche i processi completati al 100%. V$SESSION_LONGOPS è utile avere stima soprattutto indicativa e comprendere i processi in corso, anche per determinare i tempi con accuratezza occorrono test e conoscenza del sistema e delle risorse.
