ERROR at line 1:
ORA-00933: SQL command not properly ended


Error happened because missed MEMBER keyword.

Database altered.

SQL> alter database add logfile thread 2 group 6 ('+DATA/TANSID_p2/redo06a.log','+DATA/TANSID_p2/redo06b.log') size 10m;

Database altered.

Create a Standby Redo Log

alter database add standby logfile thread 1 group 13 '+DATA' size 200m;
alter database add standby logfile thread 1 group 14 '+DATA' size 200M;
alter database add standby logfile thread 2 group 15 '+DATA' size 200M;
alter database add standby logfile thread 2 group 16 '+DATA' size 200M ;
alter database add standby logfile thread 1 group 17 '+DATA' size 200M ;
alter database add standby logfile thread 2 group 18 '+DATA' size 200M ;

Can I flush the Undo tablespace by any chance... ? You don't need to flush any thing from the undo tablespace. It will reuse the undo data automatically. You can create a new undo tablespace and make it active for your database. Later on drop your old undo tablespace. UNDO_RETENTION time undo tablespace is filled and any query fails, then if another query is going to do a DML and tries to use UNDO segments then, I think that will also fail because of unavailability of UNDO SEGMENTS.. > create undo tablespace undotbl_new datafile size 1m; Tablespace created. > alter system set undo_tablespace = undotbl_new scope=both; System altered. > drop tablespace undotbs; Tablespace dropped.

How to write to a CSV file using Oracle SQL*Plus

By
  SPOOL command  The  SPOOL  command is  unavailable  in the browser-based SQL*Plus version,  iSQL*Plus . To generate files while using iSQL*Plus, change the necessary preference settings to directly output to a file. This is accomplished using the  SPOOL  statement. While  SPOOL  is  active , SQL*PLus will store the output of any query to the specified file. Therefore, the next command to enter is  spool : spool filepath Skipping ahead slightly,  after  your query is inserted, you also need to halt  spool  so the file output is closed by using the  spool off  command: spool off Insert the query  The last step after the settings are modified and  spool  is running is to insert your query. For our simple example, we’re outputting all books from our  books  table. SELECT   title,   author FROM   authors; Don’t forget the semi...
