Logical Backup Using dbms_datapump

Sample scripts to make a logical backup using dbms_datapump


-- BACKUP BY SCHEMA
declare
h1 NUMBER;
begin
h1 := dbms_datapump.open (operation => 'EXPORT', job_mode => 'SCHEMA', job_name => 'TESTE2', version => 'COMPATIBLE');

dbms_datapump.add_file(handle => h1, filename => 'BKP_SCHEMAS.LOG', directory => 'BKP_DATA_PUMP', filetype => 3);
dbms_datapump.set_parameter(handle => h1, name => 'KEEP_MASTER', value => 0);

dbms_datapump.detach(handle => h1);
end;

Index SKIP SCAN???

Index Skip Scan nada mais é que o "split" logico de um indice composto, ou seja, se sua clausula WHERE não tiver todos os campos do indice composto, ele é dividido em menores sub-indices Exemplo: -------- SQL> create table teste(a number,b number); Table created. SQL> begin 2 for i in 1..1000 3 loop 4 insert into teste values(i, 56); 5 end loop; 6 end; 7 / PL/SQL procedure successfully completed. SQL> create index idx_teste on teste(a,b); Index created. SQL> analyze table teste compute statistics; Table analyzed. SQL> explain plan for select /*+ index_ss(teste idx_teste) */ * from teste where b=56; Explained. SQL> start ?\rdbms\admin\utlxpls.sql -------------------------------------------------------------------------------- | Operation | Name | Rows | Bytes| Cost | Pstart| Pstop | -------------------------------------------------------------------------------- | SELECT STATEMENT | | 1...
