Can anybody tell me what type of lock dbms_logstdby.instantiate_table creates on the primary database table, or point me to documentation that does? I have a large table (~3.2 million rows) that I need to reinstantiate, but the primary database is part of a production system and I want to impact it as little as possible. Any other thoughts or gotchas I should look for? Environment: Oracle 10.2.0.3 EE Windows 2003 -- Jason Heinrich
