oracle table、index 的 parallel 并行度设置

table

select di.degree,di.*
from dba_tables di
where 1=1
and di.table_name='TMP_T0'
;

alter table system.tmp_t0 parallel 2;

alter table system.tmp_t0 parallel 1;
alter table system.tmp_t0 noparallel;

index

create index idx_tmp_t0 on tmp_t1(c2)  online parallel 8;

select di.degree,di.*
from dba_indexes di
where 1=1
and di.table_name='TMP_T0'
;

alter index system.idx_tmp_t0_c1 parallel 2;


alter index system.idx_tmp_t0_c1 parallel 1;
alter index system.idx_tmp_t0_c1 noparallel ;
