Hi,
Is it possible to build index partition in parallel?

I tried following command

alter index <index_name> rebuild partition <partition name> online parallel 5;

It executed without complaining, but want to know if index partitions can be build in parallel?

Thanks for your help.

Arun

What does EXPLAIN PLAN show?

Now what could we answer you? Yes, no, would you trust us? I advice you no.
Execute your statement and have a look if some Pxxx processes work.

You have to first enable parallel DDL with an ALTER SESSION statement.

Regards
Michel

Thanks. I ran the command and found entries in v$px_session and v$px_process
