Home -> Community -> Mailing Lists -> Oracle-L -> RE: DBA_SEGMENTS invalid? or slow?
The truncate command never releases the initial extent of the table or
its associated indexes if any. In the future I have heard Oracle is
going to support defining tables and indexes without allocating storage.
But at present if the table/index exists it takes at least one extent.

Subject: DBA_SEGMENTS invalid? or slow?
When I query dba_segments I get:
owner segment_name partition_name segment_type tablespace_name header_file header_block bytes blocks extentsinitial_extent next_extent min_extents max_extents pct_increase freelists freelist_groups relative_fno buffer_pool
REPADMIN T_INSTRU_LDGR T_INSTRU_LDGR_200504 TABLE PARTITION TS_LDGR_M2 71 1289 2212495360 270080 211 10485760 10485760 1 2147483645 0 1 1 71 DEFAULT Yet, when I map the tablespace, there are no extents. We have done a truncate of the partition with a drop storage, and it shows storage.
What's up with this?
