When to create index on partitioned table ?

Question

Hi,
The original table TEST1 contain one index called INDX_HIREDATE on field HIREDATE
CREATE TABLE TEST1(
COD NUMBER PRIMARY KEY,
HIREDATE DATE);
CREATE INDEX INDX_HIREDATE ON TEST1 (HIREDATE);
I created a example partitioned table as below:
CREATE TABLE TEST2_PART(
COD NUMBER PRIMARY KEY,
HIREDATE DATE)
PARTITION BY RANGE (HIREDATE)(
PARTITION P2003 VALUES LESS THAN (TO_DATE('01/01/2004','DD/MM/YYYY')),
PARTITION P2004 VALUES LESS THAN (TO_DATE('01/01/2005','DD/MM/YYYY')),
PARTITION P3000 VALUES LESS THAN (MAXVALUE));
INSERT /*+ APPEND */ INTO TEST2 SELECT * FROM TEST1;
Questions:
Need i to create the index on TEST2 table the same way done on the TEST1 table?
ex: CREATE INDEX INDX_HIREDATE ON TEST2 (HIREDATE);
or have i need to create the global/local index on each partition?
The Primary Key index is a global for partitions??
What is the best way?
Thanks

Index creation on partitioned tables is similar to the non-partitioned tables. There is no special syntax unless you need to create LOCAL indexes. For creating local indexes, add LOCAL key word at the end of the "create index...." command.
To create local primary key index you may need to use different syntax the one used in your create table command. Refer to SQL Reference manual for actual syntax. (remember manuals are the best place for getting quick answers). All the manuals are available online (at otn.oracle.com).
