Hi List, has anyone ever seen any information about Transparent Session Migration? I even discovered this subject today starting with v$tsm_session and some digging led me to DBA_TSM_SOURCE, DBA_TSM_DESTINATION, DBA_TSM_HISTORY (based on TSM_SRC$ and TSM_DST$), ORA-412xx errors, TSMSYS and cattsm.sql and at the end http://www.freepatentsonline.com/y2006/0036617.html <http://www.freepatentsonline.com/y2006/0036617.html>but all these did not give me a clue what Transparent Session Migration is or where to find any documentation about it. Or is it just a internal part of TAF? Maybe someone here can give me a hint? thank you all, Martin -- http://berxblog.blogspot.com
