LESSON 06
How to login to a pluggable database and query from it
Let us connect to mypdb1
pluggable database. First you need to open the pluggable database.
Connect to root.
# sqlplus /nolog
SQL>
connect / as sysdba
Open your pluggable
database (mypdb1).
SQL> ALTER
PLUGGABLE DATABASE mypdb1 OPEN;
Altered
Connect to mypdb1
pluggable database.
SQL>
connect system/mypass@mypdb1
Use show CON_NAME and
CON_ID
SQL> show
con_name
SQL> show
con_id
Notice that you are not
anymore in the root container.
Query the data files
using the DBA_DATA_FILES view. Assume you are connected to the mypdb1
pluggable database.
SQL> SELECT
tablespace_name, file_name FROM dba_data_files;
|
TABLESPACE_NAME |
FILE_NAME |
|
USERS |
/oradata/mycdb/mypdb1/users01.dbf |
|
UNDOTBS1 |
/oradata/mycdb/mypdb1/undotbs1.dbf |
|
SYSAUX |
/oradata/mycdb/mypdb1/sysaux01.dbf |
|
SYSTEM |
/oradata/mycdb/mypdb1/system01.dbf |
|
|
|
Notice that you only see
the mypdb1 pluggable database data files.
Query the temp file of
the mypdb1 container using the DBA_TEMP_FILES view.
SQL> SELECT
tablespace_name, file_name FROM dba_temp_files;
|
TABLESPACE_NAME |
FILE_NAME |
|
TEMP |
/oradata/mycdb/mypdb1/temp01.dbf |
Notice that the
TEMP tablespace is on the mypdb1
pluggable databases.
Notice that there is
only one spfile and password file (CDB).
# cd $ORACLE_HOME/dbs/*mycdb*
|
FILE_NAME |
|
-rw "r ------ 1 oracle dba 7682 Nov 7
00:37 spfilemycdb.ora
-rw "r ------ 1 oracle dba 7682 Nov 8
10:14 orapwmycdb |
Good Luck!
