SQL> select name from v$database;

NAME
---------
RISHI

SQL> select file_name from dba_data_files;

FILE_NAME
--------------------------------------------------------------------------------
E:\ORACLE\PRODUCT\10.2.0\ORADATA\RISHI\USERS01.DBF
E:\ORACLE\PRODUCT\10.2.0\ORADATA\RISHI\SYSAUX01.DBF
E:\ORACLE\PRODUCT\10.2.0\ORADATA\RISHI\UNDOTBS01.DBF
E:\ORACLE\PRODUCT\10.2.0\ORADATA\RISHI\SYSTEM01.DBF

Here I will be changing USERS01.DBF file location.

SQL> select open_mode,log_mode from v$database;

OPEN_MODE  LOG_MODE
---------- ------------
READ WRITE NOARCHIVELOG

SQL> select name from v$database;

NAME
---------
RISHI

SQL> shut immediate;

Database closed.
Database dismounted.
ORACLE instance shut down.

NOTE: Once database shuts down, copy the data file USERS01.DBF from old location to new location & open the database in MOUNT stage & Issue the ALTER RENAME like as below.

SQL> startup mount

ORACLE instance started.

SQL> alter database rename file  'E:\ORACLE\PRODUCT\10.2.0\ORADATA\RISHI\USERS01.DBF' to 'E:\ORACLE\PRODUCT\10.2.0\ORADATA\USE
RS01.DBF';

SQL> select file_name from dba_data_files;

FILE_NAME
--------------------------------------------------------------------------------
E:\ORACLE\PRODUCT\10.2.0\ORADATA\USERS01.DBF  - Here we can location change.
E:\ORACLE\PRODUCT\10.2.0\ORADATA\RISHI\SYSAUX01.DBF
E:\ORACLE\PRODUCT\10.2.0\ORADATA\RISHI\UNDOTBS01.DBF
E:\ORACLE\PRODUCT\10.2.0\ORADATA\RISHI\SYSTEM01.DBF

Registering The Database to RMAN catalog database:

Registering The Database to RMAN catalog database: Need to start RMAN as follows: RMAN target=sys/password@database_to_backup rcvcat=sys/password@recovery_catalog_database Another variation on the command, if the recovery catalog and the database were on the same server, might be as shown: oraenv ORACLE_SID = [KKUY] ? KKUY RMAN rcvcat=sys/password@recovery_catalog_database RMAN> connect target Recovery Manager: Release 8.0.5.1.0 - Production RMAN-06005: connected to target database: KKUY RMAN-06008: connected to recovery catalog database Use the below command to register the database.

ORA-39014: One or more workers have prematurely exited.ORA-00018: maximum number of sessions exceeded

ERROR: I was Performing a full database import and during the import I faced the below error. ORA-39014: One or more workers have prematurely exited. ORA-39029: worker 6 with process name "DW07" prematurely terminated ORA-31672: Worker process DW07 died unexpectedly. Job "SYSTEM"."SYS_IMPORT_FULL_04" stopped due to fatal error at 00:59:40 ORA-39014: One or more workers have prematurely exited. SOLUTION:  Run the import with fewer parallel processes, like PARALLEL=2 instead of 8. I was able to run the import successfully. NOTE 1: This errors occurs when there are less session allocation in the database. check the session,process parameters and increase them accordingly. To avoid such errors again. NOTE 2 : Note: Increasing processes parameter increases the amount of shared memory that needs to be reserved & the OS must be configured to support the larger amount of shared memory. So here we first need to increase the Memory & SG
