Hi all: I'm using Oracle9204 and we have been running into a following problem lately. My users execute the following command alter table owner.table exchange partition part1 with table owner.xchg_table including indexes; There is no errors, everything looks good, but when we check the counts in the table xchg_table and table partition (part1), they do not change! So it looks like the exchange did not really work. It happens intermittantly on three tables so far at different time. I can't reproduce this error. Whenever I try an exhcnage, everything looks OK (the counts do change after the exchange). I am completely frustrated by it (and my users too). Does anyone have any idea what should be the problem? I have contacted Oracle support, but did not receive anything yet. Any thought would be greately appreciated thank you Gene Gurevich -- //www.freelists.org/webpage/oracle-l
