Oracle 11gR1 RHEL5 64bit
Hi.
I am having trouble reclaiming space from a tablespace after having deleted all (thousands) of the records from a table (which resides in that tablespace). I have tried the following options to no avail:
- Alter table <table_name> shrink
- purge tablespace
- purge recyclebin
This table has several LOB columns and is using securefiles. I don't know if that has something to do with it or not. The tablespace is locally Managed and Segment space management is set to AUTO. Below is the create table command:
CREATE TABLE IIQ.DICOM_OBJECT
(
DICOM_OBJECT_RID NUMBER CONSTRAINT NN_DICOM_OBJECT_DICOM_OBJ_RID NOT NULL,
SUBMISSION_RID NUMBER,
SUBMISSION_ITEM_RID NUMBER,
DICOM ORDSYS.ORDDICOM,
IMAGETHUMB ORDSYS.ORDIMAGE,
ANONDICOM ORDSYS.ORDDICOM,
ACTIVE_FLAG VARCHAR2(1 CHAR) DEFAULT 'Y' CONSTRAINT NN_DICOM_OBJECT_ACTIVE_FLAG NOT NULL,
CREATED_TIMESTAMP TIMESTAMP(6) WITH LOCAL TIME ZONE DEFAULT SYSTIMESTAMP CONSTRAINT NN_DICOM_OBJECT_TIMESTAMP NOT NULL,
SOURCE_DESCRIPTION VARCHAR2(100 CHAR) CONSTRAINT NN_DICOM_OBJECT_SOURCE NOT NULL,
OP_CONFORMANCE_FLAG VARCHAR2(1 CHAR)
)
