TimesTen_重建业务日志表

---备份业务日志变更表

ttisql -connStr "dsn=ttstd" -e "

creaet table TIMESTEN.XIAOXU_01bak

select * from TIMESTEN.XIAOXU_01 where AVAILTIME>=to_date('20150810','yyyymmdd');

---重建业务日志表

ttisql -connStr "dsn=ttstd" -e "

alter session set ddl_replication_level=2;

alter session set ddl_replication_action='EXCLUDE';

truncate table  TIMESTEN.XIAOXU_01;

drop table  TIMESTEN.XIAOXU_01;

create table TIMESTEN.XIAOXU_01 (

        KEY_ID      TT_BIGINT NOT NULL,

        OID         TT_BIGINT NOT NULL,

        PRODUCT_OID TT_BIGINT NOT NULL,

        ATTR_ID     TT_INTEGER NOT NULL,

        "VALUE"     VARCHAR2(128 BYTE) INLINE NOT NULL,

        AVAILTIME   DATE NOT NULL,

        EXPIRETIME  DATE,

---为了加快数据导入速度，未建索引之前将数据导回

Command> insert into TIMESTEN.XIAOXU_01 select * from TIMESTEN.XIAOXU_01bak;

1 row inserted.

Command> commit;

----创建索引

Command>   create unique index TIMESTEN.PK_XIAO1 on TIMESTEN.XIAOXU_01

       >         (KEY_ID, OID, PRODUCT_OID);

17063: CREATE INDEX can only refer to empty tables when DDLReplicationLevel > 1

The command failed.        

 备注:创建失败，当主备开启ddl结构同步时，创建索引时，表必须为空。

---删除表数据

Command> delete TIMESTEN.XIAOXU_01;

1 row deleted.

Command> commit;

Command>  create unique index TIMESTEN.PK_XIAO1 on TIMESTEN.XIAOXU_01

       >         (KEY_ID, OID, PRODUCT_OID);   ---ok

alter active standby pair include table  TIMESTEN.XIAOXU_01;

alter session set ddl_replication_level=1;

exit;"

---将数据插回去操作

insert into TIMESTEN.XIAOXU_01

select * from TIMESTEN.XIAOXU_01bak;

commit;
