Oracle 10g分区表不支持自动化管理,一般都要手动创建分区,,手动删除。今天给大家带来了一个自动化管理表空间的脚本。

本脚本主要由3个部分组成:sys_ConfigTable.sql、sys_pro_AddAndDropPartition.sql、sys_pro_MergeTable.sql

1、sys_ConfigTable.sql 主要创建了一张配置表:这里填写具体要自动维护的表名、保存天数、每天分区的个数等等;

2、sys_pro_AddAndDropPartition.sql 这个用来自动增加表分区,删除过期分区;

3、sys_pro_MergeTable.sql 等每天的分区大于1时,我们合并旧的分区,并重建失效的索引。

1、sys_ConfigTable.sql

drop table CONFIGTABLE;
create table CONFIGTABLE
(
  name  VARCHAR2(64) not null,
  value  VARCHAR2(64) not null,
  type  VARCHAR2(64) not null,
  isrun  NUMBER(1) not null,
  remark VARCHAR2(64)
)
;

prompt Loading CONFIGTABLE...
insert into CONFIGTABLE (name, value, type, isrun, remark)
values ('BI_M_VISITLOCUS', 'BI_M_VISITLOCUS', 'protocal', 1, '历史记录日志表');
insert into CONFIGTABLE (name, value, type, isrun, remark)
values ('BI_M_VISITLOCUS', '1000', 'save', 1, '日志保存天数');
insert into CONFIGTABLE (name, value, type, isrun, remark)
values ('BI_M_VISITLOCUS', '1', 'num_part_byday', 1, '每天要添加的分区个数');

commit;

insert into CONFIGTABLE (name, value, type, isrun, remark)
