How can I partitioning oracle table when the table still working? How can I partitioning oracle table when the table still working?

Explain:
- I need to partitioning table of Oracle but the table didn't partitioned before.
- I have many scheduler I can't close it all.

How can I partitioning table without closing all scheduled tasks?

I try it

BEGIN
dbms_redefinition.start_redef_table(
uname =&gt; 'kiku',
orig_table =&gt; 'pletest3_pn_kiku_api_db',
int_table =&gt; 'pletest4_pn_kiku_api_db');
END;


ERROR::

Error report:
ORA-12008: error in materialized view refresh path
ORA-14400: inserted partition key does not map to any partition

12008. 00000 -  "error in materialized view refresh path"
*Cause:    Table SNAP$_&lt;mview_name&gt; reads rows from the view
           MVIEW$_&lt;mview_name&gt;, which is a view on the master table
           (the master may be at a remote site).  Any
           error in this path will cause this error at refresh time.
           For fast refreshes, the table &lt;master_owner&gt;.MLOG$_&lt;master&gt;
           is also referenced.
*Action:   Examine the other messages on the stack to find the problem.
           See if the objects SNAP$_&lt;mview_name&gt;, MVIEW$_&lt;mview_name&gt;,
           &lt;mowner&gt;.&lt;master&gt;@&lt;dblink&gt;, &lt;mowner&gt;.MLOG$_&lt;master&gt;@&lt;dblink&gt;
           still exist.
Just copy your table with a new name and apply the partioning, 
drop the original table and rename the copied file to the original table.
