Schema Refresh using ASM Diskgroups

How to create Datapump Export Dumps within ASM diskgroups

Schema Status
-------------
select username,account_status,default_tablespace from dba_users where username=upper('&username');

select owner,sum(bytes)/1024/1024 "SIZE in MB" from dba_segments where owner=upper('&owner') group by owner;

select owner,object_type,count(*) from dba_objects where owner=upper('&owner') and object_name not like 'BIN$%' group by object_type,owner order by object_type; 


EXPORT (EXPDP)

$ps -ef| grep pmon
$. oraenv
ORACLE_SID = [dbinst1] ? +ASM1
The Oracle base for ORACLE_HOME=/opt/app/11.2.0/grid is /opt/app/oracle
$asmcmd
ASMCMD> cd DATA01/TESTDB
ASMCMD> mkdir EXPDP

1. Create a directory in ASM.
SQL> create or replace directory DATAPUMP_ASM_DIR as '+DATA01/TESTDB/EXPDP';
Directory created.
SQL> GRANT READ,WRITE ON DIRECTORY DATAPUMP_ASM_DIR TO SYSTEM;

2. Create a logfile directory in filesystem, since logfiles can't be stored in ASM.
SQL> create or replace directory DATAPUMP_LOG_DIR as '/oracle/backup/testdb/expdp';
Directory created.
SQL> GRANT READ,WRITE ON DIRECTORY DATAPUMP_LOG_DIR TO SYSTEM;

3. Create logfile directory in filesystem.
$ cd /oracle/backup/testdb/
$ mkdir expdp
$ chmod -R 755 expdp
$ cd expdp
$pwd
/oracle/backup/testdb/expdp
$ df -h /oracle/backup/testdb/expdp -- or
$df -gt /oracle/backup/testdb/expdp

Where DATAPUMP_ASM_DIR is a ASM based directory
and   DATAPUMP_LOG_DIR is on a filesystem.

Here, Export is written to ASM based dictionary,
      but log is written to another directory which is on filesystem.

We can create export dumps to the ASM diskgroups. But we can’t write expdp log to ASM (as it is a text file).
