Phase 4 – Validate the transported data

Step 1: Check tablespaces for corruption

In this step, the transported tablespaces are read only in the destination database. You can validate whether the tablespaces are valid or not by running the RMAN command as follows.

sqlplus / as sysdba;
set feedback off
set pagesize 0
set heading off
spool tbs_val.sql;
select 'validate tablespace '||tablespace_name||' check logical;' from dba_tablespaces where tablespace_name not in ('SYSTEM','SYSAUX','TEMP','USERS','UNDOTBS1','UNDOTBS2','UNDOTBS3','UNDOTBS3','UNDOTBS4');
spool off;
exit;

--Remove the first and last line in the spool file, tbs_val.sql
rman target /
RMAN> @tbs_val.sql

In addition, you can check the count of the objects, such as the table, index, synonym, view, and package objects.

Step 2. Make all transported tablespaces in the destination database read/write

sqlplus / as sysdba;
set feedback off
set pagesize 0
set heading off
spool tbs_rw.sql
select 'alter tablespace '||tablespace_name||' read write;' from dba_tablespaces where status='READ ONLY';
spool off;
exit;
--Remove the first and last line in the spool file, tbs_rw.sql
sqlplus / as sysdba;
SQL> @tbs_rw.sql
