Hello Team,

I ran "exp" command to take a back of Oracle Db based on user and later imported(using "imp" command) the dump into another db.

Its seen that some the tables are not exported during exp command run. Can I use exp command on Oracle 11.2 version?

or should I always be using expdp command?

Thanks
Sunil Kumar

EXP and IMP (see Part IV) are still available in 11g, but you should not use them (see the note at the beginning of Original Export chapter). Therefore, switch to Data Pump.

With 11g imports from prior Oracle Versions I have had some corruption issues so I have had to
truncate or drop partially imported tables and import the tables one at a time after doing individual
table exports.

SCOTT > @cr8_exports_by_TABLE_NAME_on_Unix.sql

exp userid=myschema_login/myschema_password file=DEPT.dmp tables=\(DEPT\) log=DEPT.log
exp userid=myschema_login/myschema_password file=EMP.dmp tables=\(EMP\) log=EMP.log
exp userid=myschema_login/myschema_password file=BONUS.dmp tables=\(BONUS\) log=BONUS.log
exp userid=myschema_login/myschema_password file=SALGRADE.dmp tables=\(SALGRADE\) log=SALGRADE.log

SCOTT > list
  1  select 'exp userid=myschema_login/myschema_password file='||table_name||
  2* '.dmp tables=\('||table_name||'\) log='||table_name||'.log' from user_tables

SCOTT > @cr8_exports_by_TABLE_NAME_on_Windows.sql

exp userid=myschema_login/myschema_password file=DEPT.dmp tables=(DEPT) log=DEPT.log
exp userid=myschema_login/myschema_password file=EMP.dmp tables=(EMP) log=EMP.log
exp userid=myschema_login/myschema_password file=BONUS.dmp tables=(BONUS) log=BONUS.log
exp userid=myschema_login/myschema_password file=SALGRADE.dmp tables=(SALGRADE) log=SALGRADE.log

SCOTT > list
  1  select 'exp userid=myschema_login/myschema_password file='||table_name||
  2* '.dmp tables=('||table_name||') log='||table_name||'.log' from user_tables

Thank you very much for clarifying. Will not be using imp/exp command to run on Oracle 11 version.
