Unable to export empty tables

Question

I use this command:
exp userid=clix_db file=clix.dmp log=dump.log consistent=y
to export all tables from user "clix_db".
But when I take a look into the log file, I notice that not all tables have been exported. All empty tables are missed.
e.g. the table "LIC_REPORTLOG" does exists! OK, the table is empty.
But it is not exported. When I import the clix.dmp into another empty database, there is no table "LIC_REPORTLOG"
When I export only this table with
exp userid=clix_db file=clix_lic.dmp log=dump_lic.log consistent=y tables=LIC_REPORTLOG
I get an error message:
EXP-00011: CLIX_DB.LIC_REPORTLOG does not exist
If I take a look into the table "all_tables", everything is fine:
Enter user-name: clix_db
Enter password:
Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> select table_name from all_tables where table_name='LIC_REPORTLOG';
TABLE_NAME
LIC_REPORTLOG
SQL> select * from CLIX_DB.LIC_REPORTLOG;
no rows selected
Any ideas?

Hello,
I think that with such a new release you should use DataPump (expdp/impdb) to
export Tables.
For exporting a complete Schema you may use the following syntax:
expdp {color:red}+user+{color}/{color:red}+password+{color} PARFILE=pfexport.txt_With pfexport.txt as bellow:_
SCHEMAS={color:red}+schema_name+{color}
FLASHBACK_TIME="TO_TIMESTAMP(to_char(SYSDATE,'DD-MM-YYYY HH24:MI:SS'),'DD-MM-YYYY HH24:MI:SS')"
CONTENT=ALL
DIRECTORY=EXP_DIR
DUMPFILE={color:red}+dump_file_name+{color}
LOGFILE={color:red}+log_file_name+{color}Then, in this example, you'll get the "dump file" and the "log file" into the EXP_DIR Oracle directory (if it exists).
You can check your Oracle Directories with the following query:
select * from dba_directories;Then, you can use one of these Directories or create a new one with the following statement
CREATE OR REPLACE DIRECTORY {color:red}+directory_name+{color} AS '{color:red}+directory_path+{color}';
GRANT READ,WRITE ON DIRECTORY {color:red}+directory_name+{color} TO {color:red}+user_name+{color};Hope it can help,
Best regards,
Jean-Valentin
