Hi, upgrade manual says Initialization Parameters Deprecated in Release 10.2 The following initialization parameters were deprecated in release 10.2: LOGMNR_MAX_PERSISTENT_SESSIONS MAX_COMMIT_PROPAGATION_DELAY REMOTE_ARCHIVE_ENABLE SERIAL_REUSE SQL_TRACE What should I use instead of sql_trace in 10g release 2, there are still examples using sql_trace on oracle 10gr2 documentation, I'm confuse.
