Indexes

Rebuild all indexes of a Partitioned Table

“Holy rebuilding work, DBAtman!”
Cool, we have that scripted in my Utility Belt!

If you frequently need to collect all indexes of a partioned table (local and global indexes), this is a quick script that make the task a little bit easier:

begin
-- local indexes
for i in (select p.index_owner owner, p.index_name, p.partition_name
from dba_indexes i, dba_ind_partitions p
where i.owner='&OWNER'
and   i.table_name='&TABLE'
and   i.partitioned='YES'
and   i.visibility='VISIBLE' -- Rebuild only of the visible indexes, to get real effect :)
and   p.index_name=i.index_name
and   p.index_owner=i.owner
order by 1,2) loop
execute immediate 'alter index '||i.owner||'.'||i.index_name||' rebuild  partition '||i.partition_name||' online parallel 12'; -- parallel 12 solve most of the problems
execute immediate 'alter index '||i.owner||'.'||i.index_name||' parallel 1'; -- If you don't use parallel indexes in your database, or the default parallel of the index, or what you want...
end loop;
-- global indexes
for i in (select i.owner owner, i.index_name
from dba_indexes i
where i.owner='&OWNER'
and   i.table_name='&TABLE'
and   i.partitioned='NO'
and   i.visibility='VISIBLE' -- same comment
order by 1,2) loop
execute immediate 'alter index '||i.owner||'.'||i.index_name||' rebuild online parallel 12'; -- same
execute immediate 'alter index '||i.owner||'.'||i.index_name||' parallel 1'; -- same :)
end loop;
end;

Na, na, na, na, na, na, na, na, na, na, na, na… DBAtman!
