Greetings, Is it possible log_archive_start is set to true? I believe that will start the archiver process even if the database is in noarchivelog mode.

(v$database log_mode is NOARCHIVELOG). If I force a logswitch with "alter system switch logfile;" I'll get this alert log entry (without any ORA- error): Thread 1 cannot allocate new log, sequence <something>" This alone would be quite "funny", but tonight there have been jobs refusing to start with "ORA-0257 archiver error. Connect internal only, until freed.” Why is there an archiver process without archive log mode, and why is it blocking my transactions? Something you should know: The ASM disk group used by the database is 95% full, but there have been no errors with extending tablespaces or something like that. Any advice is greatly appreciated - thanks in advance! Martin Klier -- Usn's IT Blog for Linux, Oracle, Asterisk http://www.usn-it.de -- //www.freelists.org/webpage/oracle-l
