AWS RDS: Read Oracle Traces from SQL*Plus

Hi all,

One more for AWS services. Let’s say you need to read tracefiles from RDS, hot to do it?

Here is an example on how to list and read those files:

SQL> select * from dba_directories;

OWNER DIRECTORY_NAME DIRECTORY_PATH ORIGIN_CON_ID
---------- ------------------------- ------------------------------------------------------------ -------------
SYS BDUMP /rdsdbdata/log/trace 0
SYS ADUMP /rdsdbdata/log/audit 0
SYS OPATCH_LOG_DIR /rdsdbbin/oracle/QOpatch 0
SYS OPATCH_SCRIPT_DIR /rdsdbbin/oracle/QOpatch 0
SYS DATA_PUMP_DIR /rdsdbdata/datapump 0
SYS OPATCH_INST_DIR /rdsdbbin/oracle/OPatch 0
SYS TMP /rdsdbdata/userdirs/01 0

7 rows selected.


SQL> select * from table (rdsadmin.rds_file_util.read_text_file( p_directory => 'BDUMP', p_filename => 'trace/CPROD1_s003_81573.trc'));


From the trace file:
