Hi there, have looked all over and not yet found the answer to my query. I have a database instance running at 10.2.0.4.0. There is a rougue alert-{ORACLE_SID}.log created in $ORACLE_HOME/dbs directory when an instance is started. Show parameter background_dump_dest points to the correct directory - $ORACLE_ADMIN/$ORACLE_SID/bdump wether using spfile or pfile. To confirm what is happening I shutdown the instance and deleted both alert logs from the two locations and restarted the instance. Again two alert logs were created. Can anyone please advise why this is happening. I have found threads suggesting that logs are created in $ORACLE_HOME/dbs as default if parameters are not set correctly, but this is creating an alert log in two locations at startup.
in $ORACLE_ADMIN/$ORACLE_SID/bdump/alert_DBAASS06.log shows -
