疑问:Oracle-impdp 按照用户导出,导入后发现存在部分索引不存在,缺失索引是关联其它用户创建的?
???
如下测试一下:
11G 单实例测试了一下,数据泵按照用户导出,如果存在用户索引关联其它用户的表,不会被导入; SQL> show user USER is “SYS” SQL> create table system.test1 tablespace users as select * from dba_objects; SQL> grant select on system.test1 to test_usr; SQL> create table system.test2 as select * from dba_objects; SQL> grant select on system.test2 to test_usr; SQL> select tablespace_name from dba_segments where owner=‘SYSTEM’ and segment_name=‘TEST2’; TABLESPACE_NAME SYSTEM SQL> create index test_usr.ind_object_id on system.test1(object_id); SQL> create index test_usr.ind_object_id2 on system.test2(object_id); $ expdp ‘/ as sysdba’ directory=TMP dumpfile=test.dmp owner=TEST_USR CONTENT=METADATA_ONLY Processing object type SCHEMA_EXPORT/USER Processing object type SCHEMA_EXPORT/SYSTEM_GRANT Processing object type SCHEMA_EXPORT/ROLE_GRANT Processing object type SCHEMA_EXPORT/DEFAULT_ROLE Processing object type SCHEMA_EXPORT/PRE_SCHEMA/PROCACT_SCHEMA Processing object type SCHEMA_EXPORT/TABLE/TABLE Processing object type SCHEMA_EXPORT/TABLE/INDEX/INDEX Processing object type SCHEMA_EXPORT/TABLE/INDEX/STATISTICS/INDEX_STATISTICS Master table “SYS”.“SYS_EXPORT_SCHEMA_01” successfully loaded/unloaded $ impdp ‘/ as sysdba’ directory=TMP dumpfile=test.dmp sqlfile=tmp.sql Processing object type SCHEMA_EXPORT/USER Processing object type SCHEMA_EXPORT/SYSTEM_GRANT Processing object type SCHEMA_EXPORT/ROLE_GRANT Processing object type SCHEMA_EXPORT/DEFAULT_ROLE Processing object type SCHEMA_EXPORT/PRE_SCHEMA/PROCACT_SCHEMA Processing object type SCHEMA_EXPORT/TABLE/TABLE Processing object type SCHEMA_EXPORT/TABLE/INDEX/INDEX Processing object type SCHEMA_EXPORT/TABLE/INDEX/STATISTICS/INDEX_STATISTICS $ impdp ‘/ as sysdba’ directory=TMP dumpfile=test.dmp sqlfile=tmp1.sql INCLUDE=index $ cat /tmp/tmp1.sql – new object type path: SCHEMA_EXPORT/TABLE/INDEX/INDEX – CONNECT TEST_USR CREATE INDEX “TEST_USR”.“IND_C” ON “TEST_USR”.“PARTTAB001” (“COL001”) PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE(INITIAL 65536 NEXT 1048576 MINEXTENTS 1 MAXEXTENTS 2147483645 PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT) TABLESPACE “TEST_TBS” PARALLEL 1 ; ALTER INDEX “TEST_USR”.“IND_C” NOPARALLEL; CREATE INDEX “TEST_USR”.“A_ID_1” ON “TEST_USR”.“A” (“ID”) PCTFREE 10 INITRANS 2 MAXTRANS 255 TABLESPACE “TEST_TBS” PARALLEL 1 ; ALTER INDEX “TEST_USR”.“A_ID_1” NOPARALLEL;
