Hi, I'm on 4-node Linux RAC 10.2.0.3 , recently I've notice that only undo segments are showed in V$GCSPFMASTER_INFO I know that because object_id is like 4294950913 and so . Thats strange because I'm expecting other objects to be remastered, there is : |_gc_affinity_time 10 _gc_affinity_limit 50 and I can see : DRM(29) ignoring dissolve of 18504741 * kjdrchkdrm: found an RM request in the request queue Dissolve pkey 18504742 DRM(29) ignoring dissolve of 18504742 * kjdrchkdrm: found an RM request in the request queue Dissolve pkey 18504743 DRM(29) ignoring dissolve of 18504743 * kjdrchkdrm: found an RM request in the request queue Dissolve pkey 18504744 | in lmd0 trace . So how can I check DRM is on or off ?:) Regards. GregG ------------------------------------------------- Zapytaj wrozke! Sprawdz >> http://linkint.pl/f29a2 -- //www.freelists.org/webpage/oracle-l
