Hello,
All the former posts are right, alter database begin backup; doesn't exists in 9.2 althought
you already have in this release the alter database end backup;.
So as to put all the tablespaces in backup mode in one command I suggest you to create a
stored procedure as follows:
CREATE OR REPLACE PROCEDURE begin_backup IS
TYPE RefCurTyp IS REF CURSOR;
cv RefCurTyp;
sql_cv VARCHAR2(400);
tbs VARCHAR2(128);
sql_stmt VARCHAR2(200);
BEGIN
-- Mise en BEGIN BACKUP des TABLESPACES
sql_cv := 'SELECT distinct (A.name) FROM sys.v_$tablespace A, sys.v_$datafile B, sys.v_$backup C where A.TS# = B.TS# and B.FILE# = C.FILE# and C.STATUS = ''NOT ACTIVE''';
OPEN cv FOR sql_cv;
LOOP
FETCH cv INTO tbs;
EXIT WHEN cv%NOTFOUND;
sql_stmt := 'ALTER TABLESPACE '||tbs||' BEGIN BACKUP';
EXECUTE IMMEDIATE sql_stmt;
END LOOP;
CLOSE cv;
END;
Then, I just have to call the Procedure like that:
execute <schema>.begin_backup; and all the tablespaces are in backup mode.
This procedure must be created on a User/Schema with the following privileges:
alter tablespace
select on sys.v_$tablespace
select on sys.v_$datafile
select on sys.v_$backupHope it can help.
Best regards,
Jean-Valentin
