Retrieving Archived Redo Logs
If you are using Oracle Database 11.2.0.2.v7 or later, you can retain
archived redo logs and use log miner (DBMS_LOGMNR) to retrieve log information.
For example, the following command retains redo logs for 24 hours:
exec
rdsadmin.rdsadmin_util.set_configuration('archivelog retention hours',24);
Because these logs are retained on your DB instance, you need to
ensure that you have enough storage available on your instance to accommodate
the log files. To see how much space you have used in the last "X"
hours, use the following query, replacing "X" with the number of
hours.
select sum(blocks
* block_size) bytes from v$archived_log where next_time>=sysdate-X/24 and
dest_id=1;
Once you have retained the redo logs, you can use log miner as
described in the Oracle documentation.
Previous Methods for Accessing Alert Logs and
Listener Logs
You can view the alert and listener logs using the Amazon RDS console.
You can also use the following methods to access these logs:
To access the alert log, use the following command:
select
message_text from alertlog;
To access the listener log, use the following command:
select
message_text from listenerlog;
Note
Oracle
rotates the alert and listener logs when they exceed 10MB, at which point they
will be unavailable from the Amazon RDS views.
