Hi Yerong, What version are you on? What are your ARCHIVE_LOG_DEST_n settings? Any clues in alertSID.log or SID_lns.*trc files in your bdump directory? You can create a fresh lns process by changing your ARCHIVE_LOG_DEST_n for the standby with the ALTER SYSTEM command, (e.g. switch from LGWR to ARCH), perform a log switch, revert to the old ARCHIVE_LOG_DEST_n settings and perform another logswitch. Hope this helps, Best regards, Carel-Jan Engel === If you think education is expensive, try ignorance.
