hi there,
yes, you can specify storage parameters for a local index creation. for example, on a range partitioned table (EMP), you can create a local index (EMPX1) with the following sql:
CREATE INDEX empx1 ON emp (empno)
LOCAL
PCTFREE 5
STORAGE(INITIAL 8M NEXT 1M PCTINCREASE 0)
TABLESPACE empx_ts NOLOGGING PARALLEL;
please note, however, that any storage parameters specified are for EACH partition and not for whole table. e.g.:
table EMP is range partitioned by column YEARMO. the current existing partitions are:
- emp_199901
- emp_199902
- emp_199903
so the aforementioned CREATE INDEX script will create a local index with an INITIAL 8M size for EACH of the EMP partitions. so in this example, there will be 3 local 8MB indexes created, for a total size of 24MB
but if table EMP is composite partitioned. e.g:
table EMP is range partitioned by YEARMO and then hash partitioned by SSN:
(range)...emp_199901*
.....(hash)....emp_199901_a
..................emp_199901_b
..................emp_199901_c
(range) emp_199902
.....(hash)....emp_199902_a
..................emp_199902_b
..................emp_199902_c
(range) emp_199903
.....(hash)....emp_199903_a
..................emp_199903_b
..................emp_199903_c
* Please ignore all those annoying dots. i did that just to preserve the formatting.
now the aforementioned CREATE INDEX script will create 9 8MB local indexes!! one for each subpartition for a total of 72MB!
so just be careful when specifying storage parameters for a local index on a partitioned table.
have fun
