LESSON 25
How to view ADR DDL log file
If you want to view all
DDL statement, you can use the ADR DDL log file. But before using this
feature, you need to enable this feature by changing the
ENABLE_DDL_LOGGING instance parameter to TRUE
Login to your CDB.
# cd ~
# . ./.profile
# sqlplus /nolog
SQL> connect /
as sysdba
Check the value of the
DDL logging.
SQL> show
parameter ddl_logging
|
NAME |
TYPE |
VALUE |
|
enable_ddl_logging |
boolean |
FALSE |
Notice the
enable_ddl_logging value is FALSE
Enable the DDL logging.
SQL> ALTER
SYSTEM SET enable_ddl_logging=TRUE SCOPE=both;
Check the value of the
DDL logging again
SQL> show
parameter ddl_logging
|
NAME |
TYPE |
VALUE |
|
enable_ddl_logging |
boolean |
TRUE |
Notice the
enable_ddl_logging value was change to TRUE
Now, you will capture
any DDL statements that performed from administrators.
The DDL log is in the
diag folder located at $ORACLE_BASE/diag/rdbms/mycdb/mycdb/log/ddl.
You need to use the
adrci tool to view the content of the DDL log file.
Execute the adrci
utility.
# adrci
ADRCI: Release 12.1.0.1.
"
Copyright " "
ADR base = "/app/oracle"
Type the "show log"
command to view the DDL log file using your local editor such as vi.
adrci> show
log
|
2014-02-03 05:19:36.454000 +00:00 |
|
CREATE USER myuser |
|
2014-02-03 07:19:36.454000 +00:00 |
|
DROP USER myuser CASCADE |
|
2014-02-03 08:19:36.454000 +00:00 |
|
DROP TABLE scott.mytable |
|
" |
|
" |
Quit the editor by using
the :q vi commad.
:q
adrci> exit
#
You can also view the
DDL log file content using the "more" command in UNIX.
# more $ORACLE_BASE/diag/rdbms/mycdb/mycdb/log/ddl/log.xml
Good Luck!
