Fast Index Creation

I recently had to create a new index on a fairly large date ranged partitioned table. I tried a few permutations on test, but found the following steps to be the fastest;

01:01:03 SQL> alter session set workarea_size_policy=manual

Session altered.

01:13:44 SQL> alter session set hash_area_size=1073741824

Session altered.

01:13:44 SQL> alter session set sort_area_size=1073741824

Session altered.

01:13:44 SQL> select force_logging from v$database

FOR
---
YES

01:13:44 SQL> alter database no force logging

Database altered.

01:13:46 SQL>create index imei_prod.usage_profile_idx1 on imei_prod.usage_profile(msisdn)
01:13:46 2 nologging
01:13:46 3 compress
01:13:46 4 parallel 16
01:13:46 5 local
01:13:46 6 (
01:13:46 7 partition USAGE_199401 tablespace indx nologging compress,
01:13:46 8 partition USAGE_200106 tablespace indx nologging compress,
01:13:46 9 partition USAGE_200202 tablespace indx nologging compress,
01:13:46 10 partition USAGE_200207 tablespace indx nologging compress,
...
01:13:46 56 partition USAGE_200809 tablespace indx nologging compress,
01:13:46 57 partition USAGE_200810 tablespace indx nologging compress,
01:13:46 58 partition USAGE_200811 tablespace indx nologging compress
